Background: Gastrostomy tube (GT) feeding is used to promote nutrition and growth in children with chronic kidney disease (CKD). We explored the relationship between gastrostomy feeding and growth parameters in children with CKD, looking specifically at the nutritional composition of feeds. Methods: Children with CKD stages 3–5 or on dialysis in a tertiary children's kidney unit were studied. Data on anthropometry, biochemistry, and nutritional composition of feeds were collected from the time of GT insertion for 3 years or until transplantation. Results: Forty children (18 female) were included. Nineteen children were on peritoneal dialysis, 8 on hemodialysis, and 13 had CKD stages 3–5. The median (interquartile range [IQR]) age at GT insertion was 1.26 (0.61–3.58) years, with 31 (77.5%) under 5 years of age. The median duration of gastrostomy feeding was 5.32 (3.05–6.31) years. None received growth hormone treatment. Children showed a significant increase in weight standard deviation score (SDS) (p = 0.0005), weight-for-height SDS (p = 0.0007) and body mass index (BMI) SDS (p < 0.0001). None of the children developed obesity. Although not statistically significant, the median height-SDS increased into the normal range (from -2.29 to -1.85). Weight-SDS positively correlated with the percentage of energy requirements from feeds (p = 0.02), and the BMI-SDS correlated with the percentage of total energy intake as fat (p < 0.001). Conclusion: GT feeding improves weight-SDS and BMI-SDS without leading to obesity. GT feeding improved height-SDS but this did not reach statistical significance, suggesting that factors in addition to nutritional optimization need to be considered for statural growth.

In this work, the effects of deposition potential and the surface preparation, such as the cathodic activation and the sandblasting on the nucleation and growth of zinc-nickel alloy from acidic aqueous solution containing 0.47 and 0.56 M of zinc ions and nicke ions l respectively in presence of additives were studied. The zinc-nickel were deposited on as-machined and sandblasted substrates not activated or activated at 0, 50 and 150 A dm−2. The Scharifker–Hills and Palomar-Pardavé models were used to analyse the potentiostatic current-transient curves, and revealed that the nucleation of zinc–nickel remains instantaneous with a typical three-dimensional growth process, no matter the surface preparation. However, the characteristics and the features of zinc–nickel alloys coatings are vastly modified, in particular the morphology and the crystal structure, although the crystallized phase (the cubic γ-phase) remains identical. However, the preferential growth varies according to the sandblast process and thus the roughness of the substrate, which implies different crystallite size and adhesion of the coating on the substrate.

Let A be an associative superalgebra endowed with a pseudoautomorphism p. In this paper we generalize the Wedderburn-Malcev Theorem in this setting and we prove that the sequence of p-codimensions of A is polynomially bounded if and only if the variety generated by A does not contain the group algebra of Z 2 and the algebra of 2 × 2 upper-triangular matrices with suitable pseudoautomorphisms.

Nucleation and growth during the crystallization process are crucial steps that determine the crystal structure, size, morphology, and purity. A thorough understanding of these mechanisms is essential for producing crystalline products with consistent properties. This study investigates the solubility of tacrolimus (FK506) in an ethanol–water system (1:1, v/v) and examines its crystallization kinetics using batch crystallization experiments. Initially, the solubility of FK506 was measured, and classical nucleation theory was employed to analyze the induction period to determine interfacial free energy ( γ ) and other nucleation parameters, including the critical nucleus radius ( r * ), critical free energy ( ∆ G * ), and the molecular count of the critical nucleus ( i * ). Crystallization kinetics under seeded conditions were also measured, and the parameters of the kinetic model were analyzed to understand the effects of process states such as temperature on the crystallization process. The results suggested that increasing temperature and supersaturation promotes nucleation. The surface entropy factor ( f ) indicates that the tacrolimus crystal growth mechanism is a two-dimensional nucleation growth. The growth process follows the particle size-independent growth law proposed by McCabe. The estimated kinetic parameters reveal the effects of supersaturation, temperature, and suspension density on the nucleation and growth rates. [ABSTRACT FROM AUTHOR]

Shell maintenance and repair are fundamental to reproductive success and survival in shelled molluscs, yet potential links to other key processes and biological characteristics are poorly understood. Here, we examined individual associations between shell repair, risk-taking (boldness), and somatic growth; two important fitness related traits, often predicted to covary among individuals as part of pace-of-life syndromes. The pace-of-life syndrome hypothesis predicts covariation between high levels of production and behaviors associated with increased food intake (e.g. risky behavior, high foraging effort), underpinned by high metabolism, in a trade-off between early reproduction and long-term survival. Shell repair requires considerable energy investment and can interrupt periods of normal growth, thus we predicted that individual repair rates would covary negatively with boldness and growth. To test this, we examined potential (co)variation between these traits in the marine gastropod, Buccinum undatum, under controlled laboratory conditions. After accounting for sex, size, shell aperture width, and time effects, repair rates were not found to be repeatable over time, thus covariance with labile traits was not possible. Subsequent analysis revealed that bolder individuals repaired more slowly during the second stage of shell repair (but not other stages), indicating that selection might act on individual mean trait expression, and the possibility of correlated selection for these two important traits. Growth was not correlated with either boldness or repair rates. Nonetheless, our results provide novel insight to the potential relationship between shell repair and risk-taking behavior, and to the recovery capabilities of this commercially-important species following periods of disturbance. Significance: Many marine molluscs rely on shells for protection, and the rapid repair of shell damage resulting from a range of environmental factors is fundamental to overall fitness. Very few studies have examined factors affecting shell repair processes, and none have thus far examined links between shell repair and other fitness related traits (e.g. behavior and growth) at the individual level. For commercially-important species, understanding the impact of shell damage can provide insight into how populations respond and recover from interactions with fishing gear and from being discarded as bycatch. We provide the first evidence for covariation between risk-taking behavior and shell repair, where bolder individuals repair more slowly during the middle of the repair process. We also describe shell repair as a multi-stage process and suggest that individual repair rate should be considered as part of the pace-of-life syndrome in shelled molluscs. [ABSTRACT FROM AUTHOR]

This study investigates the correlation between the Gini index and gross domestic product (GDP) in two of the world's largest capitalist economies: the United States and the United Kingdom. Utilizing econometric methods, including stationarity tests and linear regression, this research work aims to elucidate the relationship between economic inequality and economic growth. The results for the United States reveal a significant positive correlation between GDP and the Gini index, suggesting that economic growth is associated with rising income inequality. In contrast, the United Kingdom shows a much weaker relationship, indicating that other factors, such as redistributive policies and social welfare programs, may mitigate the impact of economic growth on income inequality. These findings highlight the importance of national policies and institutional frameworks in shaping economic outcomes and can be used in policy making. This study contributes to the existing literature by providing a comparative analysis of the correlation between GDP and the Gini index in two major capitalist economies, offering fresh empirical insights.

The business behavior towards innovation and its impact on the creation of new jobs of 113 firms in the Valencian Community (Spain) were analyzed between 2014 and 2020. The sample included manufacturing, services and trading enterprises; technological and non-technological companies; micro-, small, medium, and large enterprises; and locations across the entire geographical extent of the Valencian Community. The firms were divided into quartiles based on their level of employment growth, linearly correlating this variable with 14 innovation indicators for each of the resulting four groups, reflecting the innovative capacity of these firms. It was found that the factor linked to innovation capacity that most favors or drives business employment creation is co-operation with other companies, as it had a direct and significant relationship with the two highest growth groups (quartiles 4 and 3), with no negative relationship with either of the two lower growth groups (quartiles 2 and 1). This suggests that the public administration should increase efforts to create spaces for the exchange of ideas between companies and organizations to reduce unemployment levels. Overall, this study provides new insights into the subject, and its findings lead to the conclusion that firms with higher innovative capacity create more jobs. [ABSTRACT FROM AUTHOR]

Rabbits can efficiently utilize plant fibers that are indigestible to humans, and hence may contribute to the alleviation of feed–food competition. Therefore, it is economically and ecologically important to genetically improve the growth performance and feed efficiency of meat rabbits. In this study, we combined pedigree, genomic, and gut microbiota data to estimate genetic and microbial parameters for nine growth and feed efficiency traits of 739 New Zealand White rabbits, including body weight (BW) at 35 (BW35), 70 (BW70), and 84 (BW84) days of age, and average daily gain (ADG), feed conversion ratio (FCR), and residual feed intake (RFI) within two age intervals of 35–70 days (ADG70, FCR70, and RFI70) and 35–84 days (ADG84, FCR84, and RFI84). Based on single-step genomic best linear unbiased prediction, three BW traits and two ADG traits had the high estimates (±standard error, SE) of heritability, ranging from 0.44 ± 0.13 of BW35 to 0.66 ± 0.08 of BW70. Moderate heritabilities were observed for RFI70 (0.22 ± 0.07) and RFI84 (0.29 ± 0.07), whereas the estimates did not significantly deviate from zero for the two FCR traits. There was moderate positive genetic correlation (±SE) between BW70 and ADG70 (0.579 ± 0.086), but BW70 did not correlate with RFI70. Based on microbial best linear unbiased prediction, the estimates of microbiability did not significantly deviate from zero for any trait. Based on the combined use of genomic and gut microbiota data, the parameters obtained in this study could help us to implement efficient breeding schemes in meat rabbits. [ABSTRACT FROM AUTHOR]

The escalating impact of human activities has led to the accumulation of microplastics (MPs) and heavy metals in marine environments, posing serious threats to marine ecosystems. As essential components of oceanic ecosystems, large seaweeds such as Caulerpa lentillifera play a crucial role in maintaining ecological balance. This study investigated the effects of MPs and cadmium (Cd) on the growth, physiology, biochemistry, and Cd accumulation in C. lentillifera while elucidating the underlying molecular regulatory mechanisms. The results demonstrated that exposure to MPs alone significantly promoted the growth. In contrast, exposure to Cd either alone or in combination with MPs significantly suppressed growth by reducing stem and stolon length, bud count, weight gain, and specific growth rates. Combined exposure to MPs and Cd exhibited the most pronounced inhibitory effect on growth. MPs had negligible impact while Cd exposure either alone or combined with MPs impaired antioxidant defenses and exacerbated oxidative damage; with combined exposure being the most detrimental. Analysis of Cd content revealed that MPs significantly increased Cd accumulation in algae intensifying its toxic effects. Gene expression analysis revealed that Cd exposure down-regulated key genes involved in photosynthesis, impairing both photosynthetic efficiency and energy conversion. The combined exposure of MPs and Cd further exacerbated these effects. In contrast, MPs alone activated the ribosome pathway, supporting ribosomal stability and protein synthesis. Additionally, both Cd exposure alone or in combination with MPs significantly reduced chlorophyll B and soluble sugar content, negatively impacting photosynthesis and nutrient accumulation. In summary, low concentrations of MPs promoted C. lentillifera growth, but the presence of Cd hindered it by disrupting photosynthesis and antioxidant mechanisms. Furthermore, the coexistence of MPs intensified the toxic effects of Cd. These findings enhance our understanding of how both MPs and Cd impact large seaweed ecosystems and provide crucial insights for assessing their ecological risks. [ABSTRACT FROM AUTHOR]

The aim of this 2022 study was to evaluate the effect of tree growth-limiting treatments on the tree yield and quality of 'Mutsu' apples. The experiment was established on 7-year-old trees on M.9 rootstock in a commercial orchard in Wilga near Warsaw. Growth-limiting treatments included unilateral root pruning, spraying the trees with Regalis Plus 10 WG at various times, and spraying with Flordimex 480 SL. Eight combinations were used, with four replicates of 20 trees per repetition. The measurements included fruit set, length of this year's shoots, yield per tree, average fruit weight, and the size structure of the yield. The distinctive physiological status of the apples was assessed directly after harvest, directly after 8 months of storage under CA conditions (1.5% CO2, 1.5% O2, 1 °C, >92% RH) and after an additional 7 days of shelf-life. Spraying trees with Regalis Plus 10 WG from the balloon stage onwards, irrespective of the treatment with root pruning, was most effective in both inhibiting long-stem growth and increasing tree yield (by almost two times) by increasing the number of apples per tree. The growth response of long-stemmed apple trees to both unilateral root pruning and Ethephon spray was significantly lower than it was to Regalis Plus 10 WG spray and had relatively little effect on their yield. Regalis Plus 10 WG resulted in a clear reduction in average fruit weight (by about 100 g), which, in the case of the large-fruited cultivar 'Mutsu', should be seen as an advantage. Its application from the balloon stage onwards promoted higher apple firmness at harvest and after simulated handling preceded by long-term storage. [ABSTRACT FROM AUTHOR]

Simple Summary: The study evaluated the effects of Rumex nepalensis leaf powder (RNL) as a natural feed additive in broiler chickens. RNL @ 10 g/kg diet improved the body weight gain and feed conversion ratio of broilers. Total serum cholesterol was decreased when RNL was added @ 5 and 10 g/kg diet. Immunity of birds was better as depicted by increase in the serum levels of immunoglobulin G and immunoglobulin M levels in RNL supplemented groups. RNL @ 10 g/kg diet was found effective in enhancing the antioxidant enzyme status of birds in terms of increased serum superoxide dismutase and decreased malondialdehyde levels. Gut health of broilers improved by RNL as recorded by favorable results in cecal microbiology and intestinal histomorphology. Thus, RNL is a promising natural feed additive for improving the growth, immuno-antioxidant status and gut health of broiler chicken. The study investigated the impact of utilizing Rumex nepalensis leaf powder (RNL) as a phytogenic feed additive on performance, blood markers, intestinal microbiology and histomorphology in broiler chicken. One hundred eighty day-old Cobb broiler chicks were randomly divided into four treatment groups having three replicates with fifteen birds each. Four iso-caloric and iso-nitrogenous diets primarily based on maize–soybean were formulated, viz., CN (Control)—fed basal diet only; RNL2.5 (basal diet + 2.5 g/kg RNL); RNL5 (basal diet + 5 g/kg RNL); and RNL10 (basal diet + 10 g/kg RNL). The results revealed a significant (p < 0.05) increase in body weight gain and feed conversion ratio in dietary treatments compared to CN with best values in RNL10 followed by RNL5. The blood markers like glucose, total protein, creatinine, alanine transaminase (ALT) and aspartate transaminase (AST) showed no significance (p > 0.05) among all the treatments, however total cholesterol significantly (p < 0.05) decreased in RNL5 and RNL10 as against CN. Regarding immune parameters, immunoglobulin G (IgG) and immunoglobulin M (IgM) levels significantly (p < 0.05) enhanced in RNL5 and RNL10. Antioxidant enzyme status showed that superoxide dismutase (SOD) increased and malondialdehyde (MDA) decreased significantly (p < 0.05) in RNL10 compared to CN. Gut health in terms of cecal microbiology and histomorphology of duodenum and jejunum were altered by inclusion of RNL in the broiler diet. A significant decrease (p < 0.05) in coliform count was recorded by incorporation of dietary treatments with highest reduction in RNL10. Lactobacillus count and total viable count did not vary significantly (p > 0.05) among dietary treatments and CN. Duodenal and jejunal villus height and villus height/crypt depth ratio were significantly (p < 0.05) increased in RNL5 and RNL10 compared to RNL2.5 and CN. Thus, it could be concluded that inclusion of Rumex nepalensis leaf powder in the diet resulted in improved performance and better immuno-antioxidant status of broilers. Further, an improvement in the gut health was observed in terms of positive effects on cecal microbiota and intestinal histomorphology of broiler chickens. [ABSTRACT FROM AUTHOR]

Simple Summary: The prickly pear (Opuntia ficus indica L.) is a hardy plant well-adapted to hot and arid environments, rich not only in fiber but also soluble carbohydrates, lipids, minerals, and other antioxidant compounds. It has recently attracted attention for its potential uses in human and animal nutrition, however its effects on rabbits are still poorly understood. Its incorporation into the rabbit diet as a source of fiber would reduce the use of alfalfa with several benefits for the sustainability of rabbit farming from the point of view of the circular economy, global warming, and meat production costs. This study investigated the use of prickly pear seed cake in the rabbit's diet with different inclusion percentages (10% and 20%). Various parameters were evaluated, including growth performance, nutrient digestibility, blood biochemical parameters, morphology of intestinal villi, and carcass characteristics. While productive parameters were similar, diets containing prickly pear seed cake led to improved digestive utilization of nutrients, as well as reduced blood lipid concentrations and fat content in the rabbit carcasses. The encouraging findings of our study suggest that the inclusion of prickly pear in rabbit feed is feasible, although further research is necessary to validate the current outcomes and to evaluate the economic convenience of its use. Prickly pear (Opuntia ficus indica L.) could be used in rabbit nutrition in compliance with circular economy principles, global warming issues, and reduction of production costs. This study aims to evaluate the effects of dietary incorporation of prickly pear seed cake (PPSC) on growth, physiological, and histometric parameters in rabbits. A total of 105 rabbits were divided into three experimental groups (n = 35) and fed different diets: a commercial feed (C group), the same feed with alfalfa replaced by PPSC at 10% (10PP group), and at 20% (20PP group). They were group-housed in cages with 5 animals per cage from weaning until slaughtering. While body weights and weight gains were similar in all groups, the coefficients of nutrient digestibility of dry matter, fibers, and ashes, as well as the characteristics of intestinal villi, were improved in the 10PP group compared to the others (p < 0.05). The 20PP group showed a reduction in perirenal and interscapular fat (p < 0.05), as well as lower plasma concentrations of triglycerides and cholesterol compared to the C group (p < 0.001). In conclusion, PPSC can be incorporated into the diets of growing rabbits up to 20% as a partial substitute for alfalfa without the impairment of growth performance. Additionally, the inclusion of PPSC enhanced nutrient digestibility and increased the intestinal absorption surface area. [ABSTRACT FROM AUTHOR]

Simple Summary: Microalgae such as Spirulina platensis and essential oils derived from Citrus limon have potential growth-promoting, antimicrobial, antioxidant, and immunostimulant effects for several fish species. This manuscript spotlights Spirulina platensis and Citrus limon essential oil and their roles in improving the performance and health of Nile tilapia. Our results indicate that Spirulina platensis and/or lemon essential oil can be used as natural feed additives during aquafeed formulation to improve fish welfare through nutritional management. The dietary presence of feed additives is crucial for boosting fish growth and immunity. Accordingly, this feeding trial aimed to investigate the effects of the separate and concurrent dietary supplementation of Spirulina platensis (SP) and bitter lemon (Citrus limon) peel essential oil (LEO) on the growth, immunity, antioxidant capacity, and intestinal health of Nile tilapia (Oreochromis niloticus). Four groups of male Nile tilapia were employed. The first group (control) was given the basal diet, while the second and third groups received the basal diet supplemented with LEO extract (1%) and SP (1 g/kg diet), respectively. The fourth group received the basal diet supplemented with a mix of LEO (1%) and SP at 1 g/kg. After two months of feeding, using LEO or/and SP improved the overall growth and immunological parameters, with their combination yielding the best outcomes. The supplementation of LEO or/and SP improved the Nile tilapia's growth metrics and transcriptomic levels of growth-regulating genes such as (oligo-peptide transporter 1 (Pep1), growth hormone receptors 1 (GHR1), and insulin-like growth factor (IGF1). The improved growth performance was linked to significant increases in the expression levels of mucin and fat metabolism-related genes. Moreover, fish supplemented with LEO, SP, or their combination showed enhanced non-specific immunological measures, including phagocytic and lysozyme activities and the mRNA copies of its regulating genes. Additionally, remarkable increases in the antioxidant enzyme activities and the mRNA levels of their related genes were detected. The complement (C3) gene's transcriptomic level was also significantly increased. Furthermore, the dietary supplementation of LEO, SP, or their combination improved the histological structures of the spleen, hepatopancreas, and intestine. The enhanced effects of LEO, SP, or their combination on fish immunity and growth are suggested to be due to their contents of bioactive compounds with anti-inflammatory, antioxidant, and antimicrobial properties. Thus, using the LOE and SP blends as feed additives is recommended for better growth and immunity of Nile tilapia. [ABSTRACT FROM AUTHOR]

Companion cropping offers a potential solution to the challenges of sustainable agriculture, such as optimizing resource use and reducing reliance on chemical inputs. The problem of achieving higher yields while maintaining environmental health remains critical. This practice enhances natural resource conservation, improves fertilization, and optimizes nutrient cycling through the balanced use of chemical and organic sources. Studies, such as those involving tree tomato and Hass avocado, have demonstrated a significant yield increase compared to monocultures, underscoring the viability of this practice. In addition to their environmental benefits, companion crops provide economic advantages by allowing producers to harvest multiple products simultaneously, thereby strengthening food security and the rural economy. This study evaluated three levels of fertilization and interactions between fruit trees at different altitudes, observing differential behavior in the variables evaluated. The combination of cape gooseberry and blackberry showed significantly positive results, with more leaves and fewer pests, demonstrating the benefits of companion plants. A trend towards the combined use of chemical and organic fertilizers was observed, a potential strategy to reduce costs and improve crop growth. The results indicated that the UF system (P. peruviana and P. vulgaris) had the highest plant height, while TF (tree tomato and bean) showed the best stem perimeter development. The incidence of pests was also significant, with Trialeurodes vaporarioum being most prevalent in the P. peruviana companion. These findings support companion cropping as a viable and promising strategy for more efficient and sustainable agriculture, offering both environmental and economic benefits. [ABSTRACT FROM AUTHOR]

In the post-economic reform period, the overall economic growth of West Bengal has been increasing. However, agricultural growth has become sluggish since the 1990s. The relatively low contribution of the secondary sector reveals an absence of a strong manufacturing base in the state. The high contribution of the tertiary sector indicates diversification and expansion of services. The time dimension for district-level analysis has been constricted by data availability. The inequality among the district is increasing, with a divergence of growth. Three development indices and a composite index reveal a significant disparity in development outcomes across districts between 2001 and 2013. The developmental gap between districts in the southern and northern parts of West Bengal has become prominent. JEL Codes: R11, 047, D63 [ABSTRACT FROM AUTHOR]

The resource curse hypothesis supposes that rents generated by resource booms create opportunities for rent-seeking activities, which weaken innovation and economic development due to the potentially adverse effects in competitive markets. The quality of institutions is an important channel to transform society from a rent-seeking economy to an entrepreneurial economy. We address in this paper these channels by examining necessity, opportunity, productive and innovative measures of entrepreneurship. Using annual data from 2002 to 2017, we estimate the relationship between entrepreneurship and natural resource rents for 60 countries. Allowing for measures of institutions (corruption, government policies, and cultural and social norms) and real GDP growth, we find that natural resource rents have negative effects on productive and innovative entrepreneurship, especially in high-income countries. In threshold dynamic panels, entrepreneurial activities grow with higher levels of corruption (weaker institutions), with an interpretation provided based on the higher corruption in developing economies.

Context: Microplastics (MPs), whether originating from primary or secondary means, have emerged as a significant global issue nowadays. Aims: The current research was designed to assess the toxicological consequences of polystyrene MPs (PS-MPs) on the growth, digestibility, body composition, haematology and histopathology of Cirrhinus mrigala fingerlings. Methods: In this study, six test diets with different MP concentrations were used, including a control group (0% MPs) and groups with 0.5, 1, 1.5, 2 and 2.5% MPs in sunflower meal-based diets. For a 90-day duration, 270 fingerlings (6.54 ± 0.02 g fish−1) were placed in triplicate groups in tanks, with each tank consisting of 15 fingerlings, feeding at a rate equivalent to 5% of their live wet bodyweight. Key results: The findings revealed a negative correlation between MP concentration and fingerlings performance, encompassing growth, digestibility, body composition, histopathology and hematology. Conclusions: The results indicate that 2.5% MPs inclusion in C. mrigala adversely affects growth, digestibility, body composition, histopathology and hematology. Implications: This research highlights the harmful effects of PS-MPs on C. mrigala fingerlings, emphasising urgent global action to address and mitigate aquatic ecosystem threats. Microplastics (MPs) have emerged as a significant global issue. The current study was conducted to evaluate toxicological consequences of polystyrene MPs (PS-MPs) that alter growth, carcass, nutrient digestibility, haematology and histopathology of Cirrhinus mrigala fish. After 90 days of trial, findings showed a negative corelation between MPs concentration and all parameters. (Image credit: Syed Makhdoom Hussain.) [ABSTRACT FROM AUTHOR]

Recently, seed priming has gained significant attention as a technique to enhance stress tolerance in various crop plants. The current research investigated the alleviative effect of s eed p riming w ith s ilicon (Si, 2 m M Na2SiO3) on the early growth and antioxidant activity of fenugreek (Trigonella foenum-graecum L.), an aromatic and medicinal plant when exposed to zinc oxide nanoparticles (ZnO NPs) toxicity levels (0, 100, and 200 mg L-1). The findings revealed that ZnO NPs toxicity had a notable detrimental effect on growth-related factors. However, Si priming proved effective in attenuating oxidative stress, promoting growth, and increasing the levels of soluble metabolites (soluble carbohydrates, soluble proteins, and free amino acids) in the presence of ZnO NPs toxicity. Moreover, Si priming significantly enhanced both enzymatic and non-enzymatic plant antioxidants compared to non-primed plants under ZnO NPs stress. Therefore, the results of this study support the use of seed priming in Si which was mostly effective in improving the growth and physiological traits of fenugreek plants by alleviating the detrimental effects of ZnO NPs toxicity.

Considering the dataset of information related to Chinese coal-fired thermal power plants during the 2005–2017 period, we initially investigated the orthogonalized response of the carbon emission to energy consumption and power generation by using Bayesian vector autoregressions and feedback solutions for impulse control technology. The results showed that the effects of energy consumption and power generation on carbon emissions were significant. The Chinese government has launched a program aimed at curbing carbon emission peaks and neutralizing or decreasing carbon emissions. The causal relationship concludes that China still needs further investment in emission abatement, improvement related to the level of openness to the outside world, and the strengthening of the construction of green zones for industrial transfer to mitigate carbon emissions.

Nitrogen (N) is a macronutrient essential for plant growth and development; insufficient N availability has an extensive impact on the overall plant metabolism and productivity. Polyamines, short aliphatic amino-containing compounds naturally produced by living cells, have been widely reported to be beneficial for plant performance under several unfavorable conditions. In this work, the role of polyamine spermine (Spm) as a priming agent for wheat growing under N deficit was investigated. Wheat seeds were primed with 0.1 mM Spm for 3 h, germinated for 48 h, and then grown in N-sufficient or N-deficient media for 8 d. Spm treatment anticipated seed germination and, though priming with Spm did not result in any stimulatory effect on plants developed under an N-sufficient medium, under N limitation many of the studied traits improved compared with control plants. Under N deficit, wheat seedlings originated from Spm-primed seeds showed increased root length, developed the third leaf earlier, and maintained higher total N and protein contents and higher nitrate reductase (NR) and glutamine synthetase (GS) activities in their leaves, compared to control plants. Likewise, total amino acids increased in the roots of primed seedlings, and carbohydrates enhanced both in roots and leaves. Our findings indicate that seed priming with Spm promotes wheat germination and early seedling growth under N limitation, mainly by promoting root elongation and N allocation to the aerial part.

The inclusion of rural smallholder farmers in the export of horticultural products has two major implications: increased household income through a promising global market, which is a catalyst for productivity, cumulatively growing Gross Domestic Product (GDP) and foreign exchange. So far, there are an estimated 2500 smallholder farmers who participate in the export of horticulture in Kenya. As a result, the current study sought to establish the nexus between quality control practices by the small holder farmers and the growth of the horticultural export market in Kenya. The study collected quantitative data using a structured questionnaire from a sample of 334 smallscale horticultural farmers who were randomly selected. Validity and reliability tests were performed before the main study. Then, descriptive and simple linear regression was used to analyze the data. Quality control practices can be measured through the Pre-production measures, Production and post-production control measures. Findings indicated that there was a statistically significant relationship between quality control practices and the growth of horticultural export markets. It was however observed that, there are weak quality control practices among the farmers which lead to non-conformities of products. This implies that the exports from Kenya become less attractive and make the smallholder farmers less competitive. [ABSTRACT FROM AUTHOR]

This study delves into the intricate dynamics of technology, labor markets, and economic growth within the context of Industry 4.0. By integrating automation capital into a dynamic general equilibrium model, we examine its implications for economic performance and social equity. The empirical analysis highlights the substitutability of unskilled labor by automation, revealing a nuanced relationship between automation adoption, the skill premium, and economic growth. Contrary to conventional wisdom, our findings suggest that a reduced ratio of unskilled to skilled labor, driven by automation, can lead to both an increase in the skill premium and sustained economic growth, even in the face of demographic challenges such as declining populations. However, this trend also exacerbates income inequality, underscoring the imperative for policy interventions aimed at promoting skill enhancement and ensuring equitable distribution of technological advancements.

Iron-rich intermetallics in Al-Si alloys pose a major challenge in aluminum recycling. Virgin Al-Si alloys typically contain a minimal iron concentration which enhances properties like tensile strength and conductivity. Although aluminum is a recycling friendly metal, Fe impurity increases due to scrap contaminations, coatings and rust, which eventually leads to the evolution and growth of detrimental Fe-rich intermetallics. These Fe-rich particles exhibit platelet or needle-like morphologies, and their aspect ratios grow with higher Si and Fe concentrations. Among the identified β phases, β-Al5FeSi is predominantly known for its fragility and negative impact on the mechanical properties of the alloy. Two potential solutions to this problem are, removing Fe from Al-Si alloys or suppressing the formation of β-Al5FeSi. While the method of alloying additions is much more viable for industry scale. Current study is a critical review of morphological modification of Fe-rich intermetallics through alloying additions to Al-Si alloys. The independent mechanism(s) of suppression of β-Al5FeSi phase by Mn, Mo, V and Cr additions is discussed along with the challenges and future scope of this work are discussed in detail.

The aim of this study was to determine the effect of oyster mushroom stem waste supplementation on the grown performance of quails. For this a total of 240 days old quails were purchased from a reputed hatchery. Equal number of chicks was assigned to four groups and each group was further replicated three times. Each replicate consisted of 20 chicks. Group PO-0 was considered as control and was fed with commercial ration with no supplementation. Group PO-1 was fed with commercial ration supplemented with 10 g mushroom waste/kg of feed. While group PO-2 and group PO-3 was fed with commercial ration supplemented with 20g and 30g of mushroom waste/kg of feed respectively. The study revealed that there was no notable impact on feed intake. However, there was a significant increase (P<0.05) in weight gain observed in the PO-3 group, accompanied by a considerably lower feed conversion ratio (FCR) in the same group. No instances of mortality were recorded in either the control or experimental groups. Nevertheless, there was a noteworthy improvement in dressing percentage observed in the PO-3 group. Additionally, the antibody titers against NDV, IBV, and IBDV were significantly higher (P<0.05) in the PO-3 group. Similarly, the histological features of the cecum, including villus height, width, and their respective ratio, were significantly higher in PO3 compared to the control group. In conclusion, this study demonstrates that supplementing the diet with various levels of oyster mushroom stem waste led to improved growth performance, enhanced immunity, and improved gut morphology in quails, all without affecting liver and kidney functions. The most favorable outcomes were achieved when oyster mushroom stem waste was incorporated at a 3% level in the feed. [ABSTRACT FROM AUTHOR]

This study aimed to evaluate the effects of three feed forms (pellet, crumble and mash) with or without CIBENZA enzyme supplementing (0.005%) on growth performance, blood parameters, and carcass traits of broiler. A total number of 576 unsexed one-day-old Cobb broiler chicks were grown over a 35-d period. Chicks were similar concerning body weight and sex. The experimental design was factorial 3x2; three forms of feed (pellet, crumble, and mash) with or without supplementing CIBENZA enzyme (0.005%) in diets. All diets were nearly iso-nitrogenous and iso-caloric based on digestible energy and contained similar levels of microelements. The results showed that chicks fed pellets diet recorded the highest final body weight, while those fed mash diet had the lowest value (P<0.001). Enzyme supplementing in diets led to a significant increase in final body weight by 1.04%, as compared with un-supplemented diets. Chicks fed pellets diet had the highest carcass weight percentage; while those fed mash diet had the lowest value (P<0.05). Serum total protein was significantly decreased with chicks fed mash diet, as compared with those fed pellets and crumble diets. Conclusively, it could be concluded that pellets feed form in broiler nutrition improved growth performance, feed efficiency, and blood metabolite profile when compared to crumble and mash feed form. Supplementation of protease enzyme in diets enhanced growth performance of broiler chickens. [ABSTRACT FROM AUTHOR]

Fruit peels have potential as prebiotic sources thanks to their dietary fiber contents. This study aimed to determine the effects of freeze-dried banana (BPP) and watermelon (WPP) peel powders on bile salt resistance, growth kinetics, and survival of Lactobacillus acidophilus and Lactiplantibacillus plantarum. In the presence of 0.5–1% bile salt, L. plantarum counts were 0.52–1.13 log CFU/mL higher in MRS broth added with 5% peel powder than without peel powder. Lactobacillus acidophilus population was 2.47–2.79 log CFU/mL higher in MRS broth added with 5% peel powder than without peel powder in the presence of 0.5% bile salt. Both peel powders did not affect the growth kinetics of L. acidophilus in milk. Conversely, the growth of L. plantarum was promoted in milk supplemented with peel powders and yielded a shorter generation time (P < 0.05). The maximum population density of L. plantarum in milk supplemented with BPP (8.68 log CFU/mL) was higher than in milk without peel powder (7.72 log CFU/mL; P < 0.05). Survival of L. acidophilus improved during storage at 4 °C in milk added with peel powders. The results suggest that BPP and WPP can be functional ingredients in probiotic foods and may be used to improve the growth and survival of probiotic cultures. [ABSTRACT FROM AUTHOR]

We aimed to investigate the effects of Bacillus cereus YB1 on the growth, intestinal digestive enzyme activity, liver antioxidant enzyme activity, and intestinal tissue structure of juvenile black rockfish (Sebastes schlegelii). A 50‐day feeding experiment was conducted. Feeding was conducted in four diet groups: control group with no YB1 supplement in diet and three treatment groups E‐L, E‐M, and E‐H containing 105, 106, and 107 CFU/g YB1, respectively. The results revealed that the weight gain and specific growth rate of juvenile fish significantly increased, while the feed coefficient was reduced in all three diet treatment groups. This indicated that the growth of black rockfish was significantly and positively affected by YB1 feeding. Enzyme activity in the intestinal tract was not significantly affected by YB1. However, the activity of protease, amylase, and lipase increased because of YB1 treatment, except for the proteases in the E‐M diet group. Meanwhile, no significant differences were recorded in the activities of the antioxidant enzymes in liver, but the level of catalase, superoxide dismutase, and malondialdehyde activities in treatments shows a better performance compared with the control in overall perspective. Furthermore, the structural features of the intestine (i.e., number of intestinal villi, length of gut villi, and thickness of muscularis) was significantly elevated with the inclusion of B. cereus YB1 in the diet. These results reveal that dietary supplementation of B. cereus YB1 is beneficial to the boosting of enzymatic activities and structure of intestinal tissue as well as the antioxidative ability of liver tissue. Such findings suggest that fish growth would be improved under YB1 feeding conditions. [ABSTRACT FROM AUTHOR]

The Delta Select channel catfish strain (DS) was developed by selection for increased growth and carcass yield. Progeny from DS and the Delta Control (DC) strain (a randomly bred strain from the same base population as DS) were compared in three trials. Trial 1: unvaccinated ~1‐year‐old fingerlings from each strain reared communally in 0.4‐ha ponds. Trial 2: vaccinated ~ 1‐year‐old fingerlings from each strain grown in separate replicated 0.4‐ha ponds and fish in about half the ponds were given an ESC vaccine‐booster at 13 months post‐hatch. Trial 3: same procedures as Trial 2, except fish were raised in replicate 0.04‐ha ponds with no vaccine‐booster. In Trial 1 DS were larger at stocking, larger at harvest, and had higher carcass yield than DC; in Trial 2 DS were larger at harvest, had better survival and higher production/ha than DC. Vaccine‐booster had no effect on fish growth or survival. DS and DC were not different for any traits in Trial 3. Although outcome varied among trials, the overall results indicated a vaccine booster did not affect growth or survival, DS strain fingerlings grew faster than DC fingerling, and DS had higher carcass yield than DC strain fish when reared communally.

The fused in sarcoma (FUS) protein is a DNA/RNA binding protein from the teneleven translocation protein family that is associated with neurodegeneration, and it has been shown to promote cell proliferation through the growth hormone/insulin-like growth factor 1 (Gh/Igf-1) signaling pathway. The zig-zag eel (Mastacembelus armatus) is a newly discovered species exhibiting sexual dimorphism in growth, and the potential role of fus in the growth and development of this species remains largely unknown. Herein, we analyzed the homology, conserved domains, evolutionary characteristics, and conserved syntenies of fus in several teleost species. The expression of fus was predominant in the brain and exhibited sexual dimorphism in the brain, muscle, and liver of zig-zag eels. We found thatmicroRNA (miR)-146-5p, miR-489-3p, and 24 other miRNAs were targeted to the fus 3' untranslated region, which might affectmuscle and bone development in adults. The igf1, insulin-like growth factor 1 receptor a (igf1ra), insulin-like growth factor 2 receptor (igf2r), growth hormonereleasing hormone-like receptor (ghrhrl), growth hormone secretagogue receptor type 1 (ghsr), and glucocorticoid receptor (gr) genes contained a higher abundance of GU-rich fus motifs compared to the other four genes analyzed in zig-zag eels. We also measured the expression of fus mRNA during fish culture at various stocking densities to further elucidate the relationship between fus expression and the Gh/Igf-1 axis. After 100 days of fish cultivation, the expression of fus and ghrhrl decreased and the expression of ghrh and gr increased as the culture density increased (p < 0.05). The expression of fus exhibited a remarkable positive correlation with a specific growth rate. These results indicate that fus mediates growth differences by regulating the expression of several growth-related genes including Gh/Igf-1 axis genes in zig-zag eels. [ABSTRACT FROM AUTHOR]

In order to optimize the parameters for reversing masculinization and establish the techniques for sex induction of pseudo-males and creation of all-female fry in largemouth bass (Micropterus salmodies, LMB), 15-day-old LMB (1.00 ± 0.10 cm in length, 0.10 ± 0.01 g in weight) were fed a diet supplemented with either 17a-methyltestosterone (MT) or letrozole (LE) and their combination. The experimental groups were M20 (20 mg/kg MT), L20 (20 mg/kg LE) and M10L10 (10 mg/kg MT and 10 mg/kg LE). The control group, named C, was not feed MT or LE. After 60 days, exogenous hormone in the diets was stopped and the effects of MT and LE on growth, male ratio, and gonadal development in LMB were evaluated. At 12-month-old, blood and gonadal tissue samples were collected to measure sex steroid hormones levels, analyze expression levels of dmrt1 and cyp19a1a genes, as well as examine the gonads morphology. The results showed no significant differences in growth between the experimental groups and the control group after a 60-day feeding period with the formulated diet (p > 0.05). The sex reversal ratio of M20, L20, M10L10 were 95.00%, 80.00%, 76.47%, respectively. The gonadal tissue sections showed that the gonadal structure of masculinized fish morphologic resembled that of control male fish. At 12-month-old, the sex reversal ratio in M20, L20, M10L10 and C groups were 100%, 86.67%, 73.33% and 50.00%, respectively. The testicular of pseudo-male fish in the M20 group exhibited well-developed morphology similarities to that of the control group males. However, the testes of pseudomale fish in the L20 and M10L10 groups were smaller size Estradiol (E2) levels in the experimental groups was significantly lower than those in the control group females (p < 0.05), while testosterone (T) levels were significantly higher than that of the control group (p < 0.05). Compared to the female fish in the control group, pseudo-male fish from all experimental groups showed significantly upregulated expression of dmrt1 (p < 0.05), and significantly downregulated expression of cyp19a1a (p < 0.05). Pseudo-males selected from group M20 exhibited a significantly higher proportion of female offspring (92.00%) compared to the control group (46.50%). In summary, 20 mg/kg MT was the optimal inducing concentration. [ABSTRACT FROM AUTHOR]

BACKGROUND AND OBJECTIVES: To meet the needs of the global population (9.7 billion people) until 2050, a 45 percent increase in corn production is required. Efforts to enhance corn production may be informed, among others, by precise nitrogen management. The objective of this study is to investigate nitrogen dynamics and accurate nitrogen nutrient management in corn farming through the utilization of a leaf chlorophyll meter and nitrogen response assessments in order to forecast corn yield in tropical upland acid soils. METHODS: The current study was conducted in an Ultisol and verified in an Oxisol. The trial was arranged in a randomized completely block design with eight treatments: 0, 45, 90, 135, 180, 225, 270, and 315 kilograms of nitrogen per hectare, repeated three times. The chlorophyll content of corn leaves was measured at 45 and 60 days after planting, using a chlorophyll meter. An analysis was conducted on the vegetative growth and yield, along with the nitrogen content in the soil, leaf, and grains. FINDINGS: The study found that the application of nitrogen fertilizer at the rate of 180 kilograms per hectare can alter nitrate concentrations in soil and significantly increase nitrogen uptake, growth, and corn yield. The nitrogen fertilizer application reached its peak at 274.5 kilograms per hectare, resulting in chlorophyll meter readings of 52.8 and a corn yield of 8.58 tons per hectare. The corn yield at the rate of maximum nitrogen fertilizer (8.58 tons per hectare) was not significantly different from that at the rate of 180 kilogrammes nitrogen per hectare (8.54 tons per hectare). A robust relationship was observed between corn yields and chlorophyll meter values, exhibiting a correlation coefficient 0.92. CONCLUSION: The study revealed that applying nitrogen fertilizer at the medium rate of 180 kilograms per hectare can increase in nitrogen uptake, growth, and corn yield on tropical upland acid soils. The corn yield did not show a notable variance between the nitrogen fertilization rate of 180 kilograms per hectare and the highest rate of 274.5 kilograms per hectare. In terms of sustainable agriculture management, the medium rate of 180 kilograms of nitrogen is recommended for maximizing crop yield on the upland acid soils and minimizing potential environmental impacts associated with the excessive use of fertilizers. A significant relationship exists between leaf chlorophyll meter measurements and corn yield, indicating that the chlorophyll meter can be utilized as a dependable instrument in the research area for establishing the most effective fertilizer levels.

BACKGROUND AND OBJECTIVES: The presence of heavy metals, specifically cadmium, in the environment poses significant threats to both ecological systems and human health. However, microalgae have shown potential in addressing this issue through their ability to absorb cadmium and produce valuable biomass, making them a promising solution for bioremediation. Among the various microalgae species, Chlorella vulgaris stands out as a suitable candidate due to its potential for biodiesel production and its capacity to effectively absorb cadmium. Therefore, the main objective of this study is to assess the toxicity of cadmium on Chlorella vulgaris cells using network meta-analysis as a methodology. METHODS: A comprehensive search was conducted on Scopus, Scilit, Google Scholar, and Web of Science to identify relevant studies published from 1 January 1990 to 16 January 2024. Only studies that reported the cell number of Chlorella vulgaris as a result of cadmium exposure were considered for inclusion. The collected data were then subjected to Bayesian frequentist network meta-analysis, utilizing standardized mean difference and a 95 percent confidence interval as measures of effect size. Additionally, a linear regression analysis was performed to examine the dose-dependent impact of cadmium toxicity. FINDINGS: Dose-dependent toxic effects of cadmium on Chlorella vulgaris were evident (R-square of more than 0.90), particularly at a concentration of 1 part per million, deemed as the maximum tolerable threshold. Prolonged exposure revealed a concentration-dependent reduction in cell viability, suggesting potential lifespan shortening. A comparison of growth stimulants, gibberellic acid and brassinolide (standard means differences of 1.7 and 3.8, respectively), in mitigating cadmium toxicity indicated the latter superior effectiveness in sustaining microalgal survivability. The presence of high nitrogen and low phosphorous levels was found to be significantly associated with a reduction in Chlorella vulgaris cells due to cadmium exposure. CONCLUSION: This research has provided conclusive proof of the harmful effects of cadmium on Chlorella vulgaris through the implementation of Bayesian frequentist network meta-analysis, offering valuable insights for environmental management practices. The findings reveal concentration-dependent effects of cadmium toxicity. The survivability of Chlorella vulgaris is determined by the compositions of macronutrients nitrogen and phosphorous. Comparative analyses highlight the superior protective effect of brassinolide over gibberellic acid in mitigating cadmium toxicity. Overall, the findings highlight the potential of Chlorella vulgaris in both bioremediation of heavy metals and biomass production. [ABSTRACT FROM AUTHOR]

Public R&D stimulates domestic private and foreign private and public R&D, together enhancing technical change and thereby GDP. In this paper, we evaluate vector-error-correction model (VECM) estimations and simulations of a companion paper in regard to internal rates of return (and related aspects) to additional public R&D of OECD countries and compare them to the macroeconomic literature. We show (i) internal rates of return to public R&D shocks, and (ii) the related payback periods, gain/GDP ratios, and sums of discounted (at 4%) gains. Fourteen of 17 countries show high internal rates of return, short payback periods, and high gains/GDP ratios from positive public R&D shocks if projects are stopped when gains get negative. Three countries show crowding-out effects and require (initial) reductions of public R&D before showing positive results. [ABSTRACT FROM AUTHOR]

This study was aimed to investigate the effects of replacing dietary fish meal (FM) with defatted yellow mealworm (Tenebrio molitor) meal (DYM) on growth performance, intestinal health, serum immune, and antioxidant indexes of juvenile Chinese mitten crab (Eriocheir sinensis). Four hundred juvenile Chinese mitten crabs (4.94 ± 0.08 g) were randomly distributed into five groups in quadruplicate (20 crabs per tank), and each group was fed with diets that replaced FM with DYM at 0% (CON, containing 200 g/kg FM), 25% (DYM25), 50% (DYM50), 75% (DYM75), and 100% (DYM100) for 8 weeks, respectively. The results showed that the growth, serum immune and antioxidant indexes, digestive enzyme activities, intestinal histology, and microbiota composition of DYM25, DYM50, and DYM75 groups all reached the similar level as the CON group. While when 100% fishmeal was replaced, significantly decreased the final body weight (FBW), weight gain (WG), serum alkaline phosphatase (AKP), acid phosphatase (ACP), lysozyme (LZM), glutathione peroxidase (GSH‐Px), total antioxidant capacity (T‐AOC), and total superoxide dismutase (T‐SOD) activities, hepatopancreas protease activity, mid‐intestine folds height and number (P < 0.05), significantly increased the feed conversion ratio (FCR), serum malondialdehyde (MDA) content, and the abundance of intestinal harmful bacteria Shewanella (P < 0.05). Overall, these results suggest that 75% dietary FM (150 g/kg) can be effectively replaced by DYM without negative impact on the growth performance, intestinal health, serum immune, and antioxidant indexes of juvenile E. sinensis.

The efficacy of herbal supplements in mitigating heavy metals (HMs) toxicity was investigated using a widely grown fish, the Nile tilapia (Oreochromis niloticus). The experiment was conducted over two phases: during the stress phase, the experimental fishes were exposed to sub-lethal concentrations of HMs, including lead, cadmium, zinc, and copper for 15 days; following which during the feeding phase, herbal supplements were given for 70 days to ameliorate their effects. Seven groups were established: the control negative group (CON−ve), control positive group (CON+ve, without any treatment), and five groups with supplementation of 1% turmeric (TUR), cinnamon (CIN), ginger (GIN), garlic (GAR), and their mixture (MIX), respectively. A total of 315 fishes were distributed evenly in experimental tanks (15 fishes per tank, in triplicates). The results revealed that exposure to HMs led to significant (p < 0.05) alterations in all the tested parameters, i.e., liver damage and growth reduction. The herbal supplements, especially the MIX groups, ameliorated the harmful effects of HMs and restored fish growth, digestibility, carcass composition, and liver health. In conclusion, the study demonstrated that the herbal supplements were effective in reducing the HMs-linked toxicity in Nile tilapia. Future studies pertaining to the mechanisms facilitated by the various herbal bioactive substances-linked tolerance to HMs in fishes are warranted. [ABSTRACT FROM AUTHOR]

ABSTRACT Plant‐based diets (PBD) have been reported throughout history, but are increasingly common in current times, likely in part due to considerable emphasis on climate change and human health and wellness. Many dietary organisations around the world endorse well‐planned, nutritionally adequate PBD, which exclude some or all forms of animal‐based foods. However, special attention must be given to patients who follow PBD and also have food allergy (FA), as avoidance may increase the risk of developing nutritional deficiencies, including poor growth in children, weight loss in adults and vitamin and mineral deficiencies. Given the increasing prevalence of both PBD and food allergen avoidance diets, healthcare providers are likely to counsel patients with FA who also follow a PBD. In this review, an overview of PBD in patients with FA is provided, including recent trends, macro‐ and micronutrient needs, and growth for children and weight gain considerations for adults. With regard to a PBD, special attention should be given to ensure adequate fat and protein intake and improving the bioavailability of several minerals such as iron, zinc, iodine, calcium and magnesium, and vitamins such as A, B2, B12 and D. Although the collective data on growth amongst children following a PBD are varied in outcome and may be influenced in part by the type of PBD, growth must be regularly monitored and in adults weight gain assessed as part of any clinical assessment in those people with FA.

Many articles examine the effect of institutions and education on economic growth in growth models or empirical settings. However, the opposite effect of economic development on institutions and education is less researched. Systematic evidence is scarce when looking at the interplay of education and institutions. Most of the literature focuses on post‐war evidence starting in the 1960s only. However, institutions and education, both, only change slowly over time and, thus, should be analysed over a longer period. In this article, we try to close a gap by examining the relationship between all three variables over 138 years. By estimating a vector error correction model for a sample of 20 Organisation for Economic Co‐operation and Development (OECD) countries, we are additionally able to differentiate between short‐ and long‐run results. We find positive effects of institutions and education on growth and vice versa. In contrast, institutions and education do not significantly affect each other. Our results are robust to several robustness tests and extensions. [ABSTRACT FROM AUTHOR]

Drought has major consequences on the growth, development, and yield of the maize crop by affecting several physiological, morphological, and biochemical processes. The effects and management techniques of maize were covered in this review. The morphological and physiological difficulties experienced by the maize crop were determined by the degree of stress and the sensitivity of the stages of the crop. It inhibits cell division, limits photosynthesis, increases plant development, diminishes leaf water potential, closes stomata, and reduces chlorophyll synthesis. Furthermore, drought stress has effects on yield and yield parameters like kernel number and grain yield per plant, biomass production, and number of kernels per ear, kernel weight, and harvest index as compared to well-watered plants. Additionally, it has an impact on respiration, translocation, nutrient metabolism, and carbohydrate metabolism. There were different management practices applied to the drought stress on the maize crop, such as breeding programs, nutrient management, plant growth-promoting bacteria, and others, that have provided an effective strategy for dealing with drought stress. In general, this analysis offers important details on the impact of drought stress on maize growth and yield as well as how to manage it. The development of plant species with a reduced water requirement, genetic engineering to create more tolerant maize varieties, and sustainable use of certain nontoxic growth regulators and antioxidant metabolism in plants under drought conditions all need more attention for future research. Finally, very few molecular marker breeding studies and gene transfers were conducted, indicating the need for more research. [ABSTRACT FROM AUTHOR]

One of the main abiotic stresses that affect plant development and lower agricultural productivity globally is salt in the soil. Organic amendments, such as compost and biochar can mitigate the opposing effects of soil salinity (SS) stress. The purpose of this experiment was to look at how tomato growth and yield on salty soil were affected by mineral fertilization and manure-biochar compost (MBC). Furthermore, the study looked at how biochar (organic amendments) work to help tomato plants that are stressed by salt and also a mechanism by which biochar addresses the salt stress on tomato plants. Tomato yield and vegetative growth were negatively impacted by untreated saline soil, indicating that tomatoes are salt-sensitive. MBC with mineral fertilization increased vegetative growth, biomass yield, fruit yield, chlorophyll, and nutrient contents, Na/K ratio of salt-stressed tomato plants signifies the ameliorating effects on tomato plant growth and yield, under salt stress. Furthermore, the application of MBC with mineral fertilizer decreased H2O2, but increased leaf relative water content (RWC), leaf proline, total soluble sugar, and ascorbic acid content and improved leaf membrane damage, in comparison with untreated plants, in response to salt stress. Among the composting substances, T7 [poultry manure-biochar composting (PBC) (1:2) @ 3 t/ha + soil-based test fertilizer (SBTF)] dose exhibited better-improving effects on salt stress and had maintained an order of T7 > T9 > T8 > T6 in total biomass and fruit yield of tomato. These results suggested that MBC might mitigate the antagonistic effects of salt stress on plant growth and yield of tomatoes by improving osmotic adjustment, antioxidant capacity, nutrient accumulation, protecting photosynthetic pigments, and reducing ROS production and leaf damage in tomato plant leaves.

The aim of this study was to reveal the effects of yeast culture replacing fish meal (FM) or chicken meal (CM) on the growth performance, serum biochemical indexes, intestinal digestive enzyme activities, hepatic antioxidant, and hepatic and intestinal histology of bullfrog (Lithobates catesbeianus). The basal diet contained 100 g/kg FM and 100 g/kg CM, and then yeast culture was used to decrease FM or CM level to 75 and 50 g/kg with yeast culture inclusion of 32 and 64 g/kg, respectively, resulting in five groups of isonitrogenous diets (control, FM75, FM50, CM75, and CM50). A total of 450 bullfrogs (45.5 ± 0.4 g initial weight) were fed the five diets for 50 days. (1) The FM50 group presented significantly lower weight gain, condition factor, hind leg index, and higher feed conversion ratio than the control group, while the other three groups of FM75, CM75, and CM50 showed no significant difference in growth performance when compared to the control group. (2) The serum triglyceride content of FM50 group was significantly lower, while the alkaline phosphatase activity was significantly higher than those of the control group. The serum total cholesterol levels were significantly lower in the CM50 group compared to the control group. (3) In intestinal digestive enzyme activities, the trypsin and α‐amylase activities in the CM75 and CM50 groups, the trypsin activity in the FM75 group, and lipase activity in the CM50 group were all significantly higher than those in the other groups. (4) The replacement of 50% FM with yeast culture (FM50 and CM50 groups) promoted the total antioxidant capacity in the liver, but compared to the control group, the intestinal villi height and muscularis propria thickness in the FM50 group were significantly lower. There was no difference (P > 0.05) in liver histology among all the groups. In conclusion, in a basal diet containing 100 g/kg FM and 100 g/kg CM, 32.0 and 64.0 g/kg yeast cultures could successfully replace 25% of dietary FM and 50% of dietary CM without negative effects on the growth performance, serum biochemical indexes, and hepatic and intestinal health of bullfrogs.

Background: Zebrafish are widely used in various research fields and to fulfil the diverse research needs, numerous zebrafish lines are available, each with a unique domestication background, potentially resulting in intraspecies differences in specific biological functions. Few studies have compared multiple zebrafish lines under identical conditions to investigate both inter- and intra-line variability related to different functions. However, such variability could pose a challenge for the reproducibility of results in studies utilising zebrafish, particularly when the line used is not clearly specified. This study assessed growth, stress status (cortisol, serotonin) and reproductive capabilities (maturity, fecundity, fertilisation rate, sperm quality) of four commonly used wild-type zebrafish lines (AB, SJD, TU, WIK) using standardized protocols. Results: The stress markers levels were found to be similar across the lines, indicating that the endocrine stress status is robust to diverse domestication histories. Variations were observed in the growth and reproductive parameters. The lines exhibited differences in the timing of puberty (86 dpf for AB and SJD lines vs. 107 dpf for the WIK line) despite achieving similar sizes, suggesting that there are line-specific variations in the induction of maturation. Additionally, the AB line demonstrated higher sperm quality than did the other lines and higher fecundity and fertilization rates than did the SJD line. The AB line also exhibiting a smaller adult size but a heavier brain relative to its body weight. Conclusion: These findings emphasize the importance of line selection for zebrafish research, indicating that researchers should consider line-specific traits to ensure the biological relevance and reproducibility of the results.

Simple Summary: Zinc oxide nanoparticles (ZnO NPs) are versatile chemicals that are widely used in various industries. In this study, the toxic effects of ZnO NPs were thoroughly investigated on Asian seabass, a polyhaline fish species that is now commercially farmed in low-salinity areas of Thailand. Asian seabass fingerlings were used as an animal model and exposed to aqueous solutions of 1–50 ppm ZnO NPs for 8 weeks. During this period, growth parameters, immune parameters and immune-related gene suppression were monitored. Water quality, histopathological alterations and Zn concentrations were also measured. Compared with the control, all ZnO NP concentrations severely inhibited growth and reduced serum levels of innate immune factors. Additionally, the highest concentration of ZnO NPs significantly decreased the expression levels of both innate and adaptive immune-related genes early in the exposure and strongly increased the mortality rate (100%) by week 6. The obtained results provide crucial toxicological data for determining the impact of ZnO NPs on Asian seabass aquaculture, particularly in industrial areas with a high contamination risk, and for assessing the biosecurity of fish consumers. In the present study, Asian seabass (Lates calcarifer, Bloch) fingerings were used as an animal model to investigate the toxicological effects of zinc oxide nanoparticles (ZnO NPs) under 5 ppt estuarine conditions. The fish were exposed to 0, 1, 5 or 50 ppm ZnO NPs for 8 weeks. It was found that ZnO NP concentrations of 5–50 ppm negatively affected several growth rate parameters, such as the weight and total length of the fish. Additionally, 5 and 50 ppm ZnO NPs led to 32.55% and 100% mortality, respectively, after 8 weeks after exposure (WAE). Furthermore, compared with the control, exposure to 1–50 ppm ZnO NPs strongly affected hematological indices, such as total blood cells, red blood cells, leukocytes and hematocrit, and suppressed lysozyme activity, superoxide anion production and bactericidal activity. High Zn concentrations accumulated in the head kidney, gills and liver, whereas low levels were detected in the gut, skin and muscle. Expression analysis of immune-related genes via quantitative real-time RT-PCR revealed that 5 and 50 ppm ZnO NPs significantly upregulated the cc and cd4 genes at 1 WAE. In contrast, 50 ppm ZnNPs downregulated the expression levels of the cd8, cc, hsp70, hsp90, tcrα, lyz and igmh genes at 1 WAE (p < 0.05). Finally, at 8 WAE, histopathological analysis revealed that 5 and 50 ppm ZnO NPs severely induced alterations in the head kidney, gills and liver. [ABSTRACT FROM AUTHOR]

Reproduction can reduce energy allocation to other life‐history traits such as survival and growth. Resource constraints give rise to (co)variation in life‐history traits and to heterogeneity in energy acquisition and allocation. At each reproductive opportunity, females face a choice between allocation to current reproduction or to maintenance. Many studies compare reproductive trade‐offs between two consecutive years, but few account for the cumulative effects of reproduction over multiple years, a crucial factor in understanding life‐history evolution in long‐lived iteroparous species. We compared short‐ (interannual) and long‐term (cumulative) reproductive trade‐offs with a 14‐year capture–mark–recapture study of eastern grey kangaroos, where females can have substantial skeletal growth for several years after maturation. We used a multivariate approach to compare how interannual and multi‐annual cumulative reproduction affected growth (n = 378 measurements), mass change (n = 376 measurements) and subsequent reproduction (n = 388 measurements), and to quantify (co)variation between these traits among individuals (n = 107) and years (n = 14). Interannually, young females that reproduced experienced decreased skeletal growth compared to young females that did not reproduce. Reproductive females of all ages experienced reduced mass gain and weaning probability in the following year. The cumulative effects of multiple reproductions included decreased skeletal growth, mass gain and weaning probability in the following year. These effects increased with age and reproductive rate. We found positive trait correlations between mass change, leg growth and subsequent reproduction among individuals and years, though weaker at the cumulative than interannual level. Females experience dynamic interannual and cumulative trade‐offs. Our analyses of cumulative costs of reproduction revealed long‐term trade‐offs as well as cumulative costs that were not apparent when estimating interannual costs. Trait correlations suggested heterogeneity in growth and reproduction among females. Years of increased growth were followed by years of increased reproduction, and years of poor growth were followed by years of poor reproduction. Our exploration of both interannual and cumulative costs of reproduction underscores the need to account for long‐term reproductive histories to better understand reproductive trade‐offs in long‐lived iteroparous species.

Drought poses a significant ecological threat that limits the production of crops worldwide. The objective of this study to examine the impact of soil applied biochar (BC) and peatmoss (PM) on the morpho-biochemical and quality traits of tobacco plants under drought conditions. In the present experiment work, a pot trial was conducted with two levels of drought severity (~ well-watered 75 ± 5% field capacity) and severe drought stress (~ 35 ± 5% field capacity), two levels of peatmoss (PM) @ 5% [PM+ (with peatmoss) and PM- (without peatmoss)] and three levels of rice straw biochar (BC0 = no biochar; BC1 = 150 mg kg− 1; and BC2 = 300 mg kg− 1 of soil) in tobacco plants. The results indicate that drought conditions significantly impacted the performance of tobacco plants. However, the combined approach of BC and PM significantly improved the growth, biomass, and total chlorophyll content (27.94%) and carotenoids (32.00%) of tobacco. This study further revealed that the drought conditions decreased the production of lipid peroxidation and proline accumulation. But the synergistic approach of BC and PM application increased soluble sugars (17.63 and 12.20%), soluble protein (31.16 and 15.88%), decreased the proline accumulation (13.92 and 9.03%), and MDA content (16.40 and 8.62%) under control and drought stressed conditions, respectively. Furthermore, the combined approach of BC and PM also improved the leaf potassium content (19.02%) by limiting the chloride ions (33.33%) under drought stressed conditions. Altogether, the balanced application of PM and BC has significant potential as an effective approach and sustainable method to increase the tolerance of tobacco plants subjected to drought conditions. This research uniquely highlights the combined potential of PM and BC as an eco-friendly strategy to enhance plant resilience under drought conditions, offering new insights into sustainable agricultural practices.

In this study, freshwater microalga (Tetradesmus obliquus GEEL-11) was cultured in municipal wastewater supplemented with various NaCl concentrations (0–150 mM). The microalgal growth kinetics, morphological changes, nutrient removals, salinity change, fatty acids (FAs) composition, and biodiesel quality were investigated. Maximum microalgal growth was observed upon 75 mM salt addition, while the increase in salt hindered the growth of T. obliquus GEEL-11. T. obliquus GEEL-11 exhibited high nutrient removal N (87–99%) and P (94–100%) from municipal wastewater under various salt stress. The cell size of T. obliquus GEEL-11 increased and intracellular vesicular structures proliferated. The salinity dramatically decreased, indicating that T. obliquus GEEL-11 might be able to remediate saline wastewater. The palmitic acid (C16:0) and stearic acid (C18:0) accounted for 28.90–34.02% and 43.61–62.09% of T. obliquus GEEL-11, respectively. T. obliquus GEEL-11 exhibited significant quantities of fatty acids, representing its potential for biodiesel production. This study demonstrated that T. obliquus GEEL-11 could effectively remove N and P from wastewater embedded with high salt concentrations for biomass production. [ABSTRACT FROM AUTHOR]

Arabidopsis thaliana sepals are excellent models for analyzing growth of entire organs due to their relatively small size, which can be captured at a cellular resolution under a confocal microscope. To investigate how differential growth of connected cell layers generate unique organ morphologies, it is necessary to live-image deep into the tissue. However, imaging deep cell layers of the sepal (or plant tissues in general) is practically challenging. Image processing is also difficult due to the low signal-to-noise ratio of the deeper tissue layers, an issue mainly associated with live imaging datasets. Addressing some of these challenges, we provide an optimized methodology for live imaging sepals, and subsequent image processing. For live imaging early-stage sepals, we found that the use of a bright fluorescent membrane marker, coupled with increased laser intensity and an enhanced Z- resolution produces high-quality images suitable for downstream image processing. Our optimized parameters allowed us to image the bottommost cell layer of the sepal (inner epidermal layer) without compromising viability. We used a 'voxel removal' technique to visualize the inner epidermal layer in MorphoGraphX image processing software. We also describe the MorphoGraphX parameters for creating a 2.5D mesh surface for the inner epidermis. Our parameters allow for the segmentation and parent tracking of individual cells through multiple time points, despite the weak signal of the inner epidermal cells. While we have used sepals to illustrate our approach, the methodology will be useful for researchers intending to live-image and track growth of deeper cell layers in 2.5D for any plant tissue.

Caulerpa lentillifera is a green alga that contains essential nutrients. This study investigated the effects of autoclave- and microwave-assisted C. lentillifera extracts (A-CLE and M-CLE) on the growth, reproduction, immunity, and oxidative stress in Daphnia magna. Both extracts were supplemented to D. magna at 1 to 5 g/L. The results showed that D. magna treated with 2 to 5 g/L of A-CLE produced juveniles faster than the control. Juveniles at 1 to 4 g/L A-CLE treatments increased. Moreover, juveniles in 1 g/L M-CLE treatment significantly increased, but the hatching time was not affected. A-CLE also stimulated the immunity of D. magna by increasing hemocytes in the 3 g/L treatment. Furthermore, both extracts did not affect the growth rate, phenoloxidase activity, malondialdehyde level, and catalase activity in D. magna. Therefore, our results indicated that both extracts could enhance the reproduction and immunity of D. magna. Our study is useful for the health improvement of D. magna. [ABSTRACT FROM AUTHOR]

AbstractIn hydroponics, preferring a higher nitrate to ammonia ratio can lead to nitrate accumulation in plant tissues. Reducing nitrate application and substituting nitrate-based fertilizers with ammonium or urea can help solve this issue. Additionally, adding molybdenum (Mo) can decrease nitrate accumulation by stimulating nitrate reductase activity. This study was carried out in a factorial design within a completely randomized experimental setup to investigate the effects of varying nitrate, ammonium, and urea ratios, as well as Mo concentration in the nutrient solution, on vegetative growth and biochemical parameters in hydroponically grown Jenovise basil. The treatments included different ratios of nitrate: ammonium: urea (75:25:0, 50:25:25, 25:25:50, 0:25:75, 50:0:50, 25:0:75, 0:0:100, or 100:0:0) and three Mo levels (0.001, 0.01, 0.1 mg. L−1) in a modified Hoagland solution. The results indicated that growth-associated characteristics improved when nitrate was partially substituted with ammonium and urea in the nutrient solution. The highest total phenolics (2.61 mg. g−1 DW) and flavonoids (2500.36 mg. g−1 DW) were observed at a nitrate: ammonium: urea ratio of 75:25:0 with 0.1 mg. L−1 Mo. Plants treated with a nutrient solution containing a nitrate: ammonium: urea ratio of 0:25:75 and 0.01 mg L−1 Mo showed a significant increase in chlorophyll b concentration, reaching 0.22 mg.g−1 FW, which was higher than all other treatments. In conclusion, our findings demonstrated that optimizing the combined nitrate, ammonium, and urea ratios along with Mo in the nutrient solution regulated nitrate accumulation and growth in hydroponically grown basil.

Riverine fishes face many challenges including habitat degradation and climate change, which alter the productivity of the riverscapes in which fish live, reproduce, and feed. Understanding the watershed portfolio of foraging and growth opportunities that sustain productive and resilient fish populations is important for prioritizing conservation and restoration. However, the spatiotemporal distribution and availability of fish food are poorly understood relative to other factors such as abiotic habitat quantity and quality (e.g., water temperature). In this paper, we build on the concept of “foodscapes,” and describe three components of food for fish, including abundance, accessibility, and quality. We then discuss methodological advances to help address three key questions: (1) Why is food availability hard to estimate? (2) What are the consequences of uncertainty in food availability estimates? and (3) What approaches are available or emerging for quantifying food available to fish? To address the first question, we characterize data acquisition and analytical challenges; for the second, we demonstrate the importance of evaluating and communicating potential consequences of uncertainty; and for the third, we posit opportunities for future work. Collectively, we highlight the need for greater appreciation of the role food plays in stream fish conservation, especially given its critical influence on responses to warming temperatures.This article is categorized under: Water and Life > Nature of Freshwater Ecosystems Water and Life > Conservation, Management, and Awareness Water and Life > Methods [ABSTRACT FROM AUTHOR]
