Abstract 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

Abstract Background This research investigated the impact of selenium-nanoparticles (Se-NPs) supplemented in sunflower meal (SM)-based diets on digestibility, mineral absorption, and growth performance of Catla catla. Se-NPs were added to seven test meals in varying amounts (0, 0.5, 1, 1.5, 2, 2.5 and 3 mgkg− 1). A total of 315 fish were evenly allocated three replicate tanks, with 15 fish per tank, and given diets equivalent to (5%) of their wet biomass daily for a period of 90 days. Results The test diet (T-D) supplemented with 1.5 mgkg− 1 Se-NPs yielded remarkable results, including a significant increase in mean weight gain (14 g), an impressive average weight gain percentage (208%), a 100% survival rate, with no mortality observed and the highest specific growth rate (1.25). Moreover, 1.5 mgkg− 1 Se-NPs (T-D-IV) demonstrated superior nutritional digestibility (CP, 76%; CF, 79% and GE, 74%). Additionally, the diet 1.5 mgkg− 1 Se-NPs showed enhanced mineral absorption (K, P, Ca, Na, Zn, Cu and Fe) than other diets. Conclusion It was practically proven that the growth indices, nutrient absorption, and mineral status of C. catla were significantly improved by Se-NPs supplemented SM-based diets, with the optimum level of supplementation being 1.5 mgkg− 1.

As an alternative to synthetic chemicals, natural herbs can greatly improve fish's health and growth potential. This investigation aimed to explore the possibilities of oregano (Oregano vulgare L.) extract as a phytogenic feed additive in improving the growth, blood profile, carcass composition, whole-body mineralization, serum biochemistry and antioxidant activity of Catla catla (average initial weight = 9.26±0.03 g/fish). Triplicate groups of fish were fed diets having various percentages of oregano extract (0 %, 0.5 %, 1 %, 1.5 %, 2 %, 2.5 % and 3 % per kg diet) twice daily for 90 days. The findings found that parameters of growth such as weight gain, weight gain%, feed conversion ratio, survival rate, protein efficiency ratio, and specific growth rate increased substantially (p

Herbal supplements can effectively boost fish growth and are a cost-effective alternative to antibiotics. The main objective of this research was to explore the efficacy of leaf extract of Solanum nigrum (SNE) on the growth parameters, digestibility, carcass, blood indices, and antioxidant status of Oreochromis niloticus fingerlings (5.75±0.03 g/fish). Canola meal was used as basal diet. Six experimental treatments having different levels of SNE (0 %, 0.5 %, 1 %, 1.5 %, 2 % and 2.5 %) were formulated. 15 fingerlings were placed in each of 6 triplicate tanks. The feeding trial continued for 70 days and then the results showed improvement in growth indices, body composition (fat, protein, ash and moisture) and nutrient absorption (crude fat, gross energy and crude protein) of O. niloticus. Moreover, SNE treatment showed better results of blood indices. Best outcomes for all these parameters were observed at 1.5 % SNE supplementation (test diet-IV). Additionally, SNE treatment enhanced the antioxidant activity of O. niloticus. The serum antioxidant enzymes status (catalase, superoxide dismutase and peroxidase) were enhanced by SNE treatment. Antioxidant activity increased with increasing SNE supplementation. In conclusion, SNE improved the growth and overall health of O. niloticus and the optimum inclusion level suggested for SNE is 1.5 %. However, further research is necessary to ensure its safe and effective use in different fish species.

Abstract Oreochromis niloticus fingerlings (5.15 ± 0.02 g; n = 315) were fed with different types of biochar (BC)-supplemented sunflower meal-based (SFM) diet to investigate the effects of various BC inclusions on their nutritional digestibility, body composition, hematology and mineral status for 60 days. Seven different diets were formulated based on the SFM based diet: one was a control (TD-I, CON) and the other six diets were supplemented with 2% BC derived from different sources. These BCs were derived from the following: cotton stick (CSBC, TD-II), wheat straw (WSBC, TD-III), corn cob (CCBC, TD-IV), house waste (HWBC, TD-V), grass waste (GWBC, TD-VI), and green waste (GwBC, TD-VII) biochar. There were three replicates for each test diet. Each tank had fifteen tilapia fingerlings, and they were fed with 5% of their live wet weight and twice daily. The outcomes showed that the supplementation of CCBC significantly elevated the growth, nutrient absorption, and body composition of the O. niloticus fingerlings (p

The fall armyworm, Spodoptera frugiperda (J.E. Smith), is a devastating pest that attacks a wide range of crops, including sugarcane, rice, and maize. The purpose of this study is to evaluate the toxicity potential of native plant extracts (Azadirachta indica, Eucalyptus globulus, Parthenium hysterophorus, Cannabis sativa, Citrullus colocynthis, Nicotiana tabacum) against S. frugiperda. Four different concentrations (50, 100, 200, and 400 ppm) of the ethanolic plant extracts was evaluated against S. frugiperda third-instar larvae to determine their median lethal concentration (LC50). After 72 h of exposure, the LC50 values of A. indica, E. globulus, P. hysterophorus, C. sativa, C. colocynthis, N. tabacum, and positive control (Spinetoram) were 186.104, 518.438, 320.027, 334.259, 252.651, 720.980 and 189.369 ppm respectively. The maximum percent mortality was caused by the highest concentration (400 ppm) of A. indica (64 ± 0.18), E. globulus (48 ± 0.22), P. hysterophorus (56 ± 0.18), C. sativa (56 ± 0.18), C. colocynthis (60 ± 0.00), and N. tabacum (40 ± 0.28), after 72 h of treatment while Spinetoram induced 100 ± 0.00 percent mortality of S. frugiperda and only 4 ± 0.18 percent mortality was recorded in a control group. Results showed that all plant extracts were found to be effective against S. frugiperda. The compounds from the two most effective ethanolic plant extracts were identified by using Gas chromatography-mass spectrometry analysis (GC-MS). The key compounds identified in neem leaf extract and kortuma fruit extract are predominantly biologically active molecules. Many of them were volatile compounds that belonged to different chemical categories, such as fatty acids, hydrocarbons, esters, terpenoids, phenolic compounds, and amines. Terpenes exhibited a wide range of different biological activities, such as serving as insecticides and antifeedant. The presence of various functional groups in the plant extract was determined by conducting a Fourier Transform Infrared Spectroscopy (FTIR). Farmers should employ these kinds of environmental friendly insecticides to lessen the impact of fall armyworm because these products are cheaper to use and better for the economy and the environment.

The widespread presence of microplastics (MPs) in aquatic ecosystems raises concerns about their potential harm to aquatic life, particularly fish, which are a vital source of protein for human consumption. It emphasizes the importance of examining their occurrence and impacts. The focus of this study was to find out deleterious effects of polylactic acid MPs (PLA-MPs) on the Catla catla fingerlings by observing their growth, body composition, digestibility, histopathology, blood health, and mineral analysis. Utilizing sunflower meal (SFM) as the basal diet, six test diets were formulated, incorporating distinct MP concentrations: control (no MPs), 0.5 %, 1 %, 1.5 %, 2 %, and 2.5 %. These test diets were tested in three replicates of 15 fingerlings per tank and fed at 5 % equivalent of their live wet body weight for 90 days. After exposure to 2.5 % MPs, C. catla, fingerlings showed a significant decline in growth rate and feed utilization. Increased FCR and decreased WG (g) were observed in 2.5 % PLA-MPs. As MP levels increased, nutrient digestibility and minerals content decreased. PLA-MPs increased body fat and moisture, but decreased protein and ash content. MP exposure leads to significant changes in hematological parameters, including decreased RBCs, Hb, PLT, PCV, and MCHC, and increased WBCs, MCH, and MCV. Furthermore, histopathological examination of the gut showed increased intestinal abnormalities at the 2.5 % PLA-MPs concentration. This study underscored the adverse effects of PLA-MP pollution on the overall health performance of C. catla fingerlings.

Animal health is generally improved by biochar (BC), a promising dietary supplement made from various organic materials including wheat straw, corn cob, home trash, agricultural waste and wood waste. In the current investigation, effects of different BCs inclusion on the growth, digestibility, body composition, hematological indices and mineralization of Ctenopharyngodon idella (6.11±0.02 g; n = 315 fish) fed diets based on sunflower meal (SFM) were investigated over a 60-day period. Seven diets were prepared: first was the control diet i.e., CON and six other diets were supplemented with 2 % different types of BCs, i.e., cotton stick BC (CSBC), wheat straw BC (WSBC), corn cob BC (CCBC), house waste BC (HWBC), grass waste BC (GWBC), and green waste BC (GwBC). A triplicate tank design was employed for each experimental diet, with fifteen fingerlings per tank. Throughout the experimental duration, they were fed 5 % of their live wet weight. The results revealed that CCBC supplementation significantly (p

IntroductionProbiotics, one of functional feed additives (FFAs), have emerged as a potential supplement to strengthen fish health and mitigate oxidative stress. The main focus of our research was to explore the benefits of probiotics (protexin) on growth, digestibility, antioxidant enzyme activity, and blood indices of Cirrhinus mrigala fingerlings.MethodsA total of 105 fish (7.42 ± 0.02 g/fish) were used in a 90-day feeding trial. Fish were fed two times a day, and diets were tested in triplicate tanks (15 fingerlings per tank). Moringa oleifera seed meal was chosen as a basal feed ingredient. Seven test diets were formulated: One was control (without supplement), and six diets had different concentrations of probiotics, such as 0.5, 1, 1.5, 2, 2.5, and 3 g kg−1.ResultsThe results of growth and nutrient absorption were maximum at a probiotic concentration of 2 g kg−1. The optimal serum antioxidant enzyme activity and blood parameters were likewise obtained at a probiotic dose of 2 g kg−1.ConclusionsSupplementing C. mrigala with 2 g kg−1 probiotics substantially improved their growth, nutrient digestibility, antioxidant enzyme activity, and hematological indices (p < 0.05).

Monoterpenoids are interesting hydrocarbons typically found in essential oils and have a significant role in medicinal and biological purposes. The goal of this study was to investigate the effects of two monoterpenoids, carvacrol (CAR) and menthol (MEN), supplemented with Moringa oleifera leaf meal (MOLM) based diets on growth parameters, digestibility and body composition of Nile tilapia (Oreochromis niloticus). Alongside the basal diet (control-T1), nine experimental diets supplemented with categorized levels of CAR and MEN at 200, 300 and 400 mg/kg individually and their mixtures (MIX) (1:1) (CAR-T2, 200; T3, 300; T4, 400 mg/kg, MEN-T5, 200; T6, 300; T7, 400 mg/kg and MIX- (1:1) T8, 200; T9, 300; T10, 400 mg/kg) were fed to the fingerlings (6.55 ± 0.03 g) for the period of 60 days. Monoterpenoids supplementation led to significantly (p

Tamarindus indica, a beneficial herb, has many health benefits but there is limited research on its use in fish nutrition industry. The current study investigated the effects of incorporating extracts of T. indica into the canola meal-based diets of Cyprinus carpio (common carp); following which, the growth, digestibility, carcass and hematological markers were assessed. A total of six diets were formulated with varying concentrations of T. indica extracts (TIE) viz, 0 %, 0.5 %, 1 %, 1.5 %, 2 % and 2.5 %. The fish (N = 270, 15 fish/tank with triplicates) in each tank were fed experimental diets for 70 days. The study demonstrated that TIE supplementation significantly improved the growth of common carp when compared to 0 % TIE level (control). The best results were observed at 1 % TIE level for the specific growth rate (1.68 ± 0.03 %), weight gain (15.00 ± 0.57 g), and feed conversion ratio (1.36 ± 0.05). Conversely, the 2.5 % TIE level gave the least improvement in terms of growth performance. Specifically for nutrient digestibility, the maximum values of crude protein (CP, 67.60 ± 0.83 %), crude fat (CF, 67.49 ± 0.45 %) and gross energy (GE, 70.90 ± 0.56 %) were recorded at 1 % TIE level. In addition, the best results of body composition (protein: 63.92 ± 0.06 %, ash: 18.60 ± 0.03 %, fat: 7.12 ± 0.02 % and moisture: 10.36 ± 0.04 %) and hematological indices, were measured in carps fed with 1 % supplementation level. In conclusion, the overall health of C. carpio fingerlings was improved with TIE supplementation in the diet containing 1 % TIE.

Recently, aquaculture species have been facing various negative consequences of ingesting microplastics (MPs). In order to find out the adverse impacts of MPs, this study aimed to assess growth, body composition, nutrient digestibility, hematological indices and gut histopathology of Catla catla fingerlings by the dietary exposure of polystyrene MPs (PS-MPs). C. catla (initial weight, 7.03±0.02 g; n, 270) were given PS-MPs at different inclusion concentrations i.e., 0 %, 0.5 %, 1 %, 1.5 %, 2 % and 2.5 % for 90 days. Fish were fed twice a day, about 5 % of their live weight. The water quality parameters such as temperature (25–27 °C), pH (7.3–8.3), dissolved oxygen (5.4–7.2 mg/L) were maintained at the regular basis throughout the experiment. PS-MPs significantly (p

IntroductionIn the current study, Cirrhinus mrigala was used as an animal model to investigate the impacts of Moringa oleifera leaf meal (MOLM) on their overall performance reared in six earthen ponds.MethodsIn this study, fishmeal (FM) was substituted with MOLM at various levels in the diet: 0% (control), 10, 15, 20, 25, and 30%, for a six-month feeding trial. A total of 270 fish with 15 fingerlings (15.31 ± 0.12 g/fish) stocked in each of the six earthen ponds in triplicates.ResultsWhen compared to other experimental and control groups, analyses revealed that fish given a diet having 10% MOLM had the highest growth performance (final weight: 422.32 g, weight gain: 406.97 g). Fingerlings fed a diet which substituted with 10% of FM with MOLM showed the greatest results for body composition (crude protein: 19.31%; crude fat: 3.01%). The results of hematology, i.e., WBCs: 7.65 × 103 mm−3, PLT: 58.38, hemoglobin level: 8.52 g 100 mL−1, PCV: 25.12%, MCHC: 30.45%, MCH: 48.81 pg., MCV: 159.50 fl, also showed that 10% MOLM was the optimum level for FM substitution. Furthermore, the outcomes of body mineralization (P, Ca, Na, Mn, Fe, Mg, Zn, K, and Cu, 1.06, 0.92%, 5.53 mg/g, 9.90 ug/g, 54.62 ug/g, 3.09%, 3.81 ug/g, 8.31%, and 3.76 ug/g respectively) also indicated that 10% level was the best.ConclusionConclusively, the current study found that substituting 10% of FM with MOLM in the diet of C. mrigala fingerlings improved growth performance, carcass, hematology, and mineral status.

Abstract Microplastics (MPs) are emerging pollutants that may affect the aquatic life, including fish, raised in aquaculture. The purpose of this study was to determine the effects of biodegradable-MPs mixed in canola meal based diet on the growth performance, body composition, nutrient digestibility and gut content of grass carp fingerlings. For this purpose, six canola meal based diets were prepared including one control diet (without addition of MPs) and five other diets containing 1%, 3%, 5%, 7% and 9% MPs. 270 fingerlings were fed twice for 60 days at a rate of 5% of their wet weight. Effect of each treatment on the weight gain, feed conversion ratio (FCR), nutrient digestibility, gut performance and body composition was calculated by standard procedures. Highest value for growth, nutrient digestibility and no damage to gut was observed in fish fed control diet. Results showed that there was significant decrease (P

High protein content, excellent amino acid profile, absence of anti-nutritional factors (ANFs), high digestibility and good palatability of fishmeal (FM), make it a major source of protein in aquaculture. Naturally derived FM is at risk due to an increase in its demand, unsustainable practices, and price. Thus, there is an urgent need to find affordable and suitable protein sources to replace FM. Plant protein sources are suitable due to their widespread availability and low cost. However, they contained certain ANFs, deficiency of some amino acids, low nutrient bioavailability and poor digestibility due to presence of starch and fiber. These unfavourable characteristics make them less suitable for feed as compared to FM. Thus, these potential challenges and limitations associated with various plant proteins have to be overcome by using different methods, i.e. enzymatic pretreatments, solvent extraction, heat treatments and fermentation, that are discussed briefly in this review. This review assessed the impacts of plant products on growth performance, body composition, flesh quality, changes in metabolic activities and immune response of fishes. To minimize the negative effects and to enhance nutritional value of plant products, beneficial functional additives such as citric acid, phytase and probiotics could be incorporated into the plant-based FM. Interestingly, these additives improve growth of fishes by increasing digestibility and nutrient utilization of plant based feeds. Overall, this review demonstrated that the substitution of fishmeal by plant protein sources is a plausible, technically-viable and practical option for sustainable aquaculture feed production.

The exploitation of natural products and their analogues in the field of pharmacology has been regarded as of great importance. It can be attributed to the fact that these scaffolds exhibit diverse chemical properties, distinct biological activities and zenith specificity in their biochemical processes, enabling them to act as favorable structures for lead compounds. The synthesis of natural products has been a crafty and hard-to-achieve task. Steglich esterification reaction has played a significant role in that area. It is a mild and efficient technique for constructing ester linkages. This technique involves the establishment of ester moiety via a carbodiimide-based condensation of a carboxylic acid with an alcohol, thiol or an amine catalyzed by dimethyl aminopyridine (DMAP). Specifically, labile reagents with multiple reactive sites are esterified efficiently with the classical and modified Steglich esterification conditions, which accounts for their synthetic utility. This review encloses the performance of the Steglich esterification reaction in forging the ester linkage for executing the total synthesis of natural products and their derivatives since 2018.

This research aimed to see how effectively chromium nanoparticles (Cr-NPs) improve minerals absorption and carcass composition in Catla catla fingerlings given sunflower meal based diets. In a 90-day experimental design, seven test diets were supplemented with graded levels of nano-Cr (0, 0.5, 1, 1.5, 2, 2.5, and 3 mg kg−1) and 15 fingerlings (initial weight; 6.83 ± 0.077 g) were kept in triplicate (25–28 °C). Feed was provided to fingerlings at the rate of 5% of their wet weight and fed twice a day. As an inert marker, chromic oxide was used. The highest effectiveness in minerals absorption (Ca, Na, K, Cu, Fe, Mn, P, Cr, Mg, Zn and Al) was observed at 2 mg kg−1 Cr-NPs supplementation. These levels were statistically more significant (p

Sharpless asymmetric dihydroxylation is an important reaction in the enantioselective synthesis of chiral vicinal diols that involves the treatment of alkene with osmium tetroxide along with optically active quinine ligand. Sharpless introduced this methodology after considering the importance of enantioselectivity in the total synthesis of medicinally important compounds. Vicinal diols, produced as a result of this reaction, act as intermediates in the synthesis of different naturally occurring compounds. Hence, Sharpless asymmetric dihydroxylation plays an important role in synthetic organic chemistry due to its undeniable contribution to the synthesis of biologically active organic compounds. This review emphasizes the significance of Sharpless asymmetric dihydroxylation in the total synthesis of various natural products, published since 2020.

Heavy metals are released into the environment through both human and natural sources, may have a direct hepatic toxicity and are involved in chronic liver diseases. Modification in the regulation of heavy metals metabolism enhanced hepatitis c virus (HCV) replication which ultimately reduced outcomes of anti-viral therapy in chronic HCV patients. Chelation therapy with new drugs seems to eradicate HCV and may prevent liver complications. The present study was planned to explore the effects of MiADMSA (lipophilic chelating agent) for achieving maximum heavy metals elimination in hepatitis c virus patients with minimum side effects. For this purpose concentration of heavy metal was determined in HCV patients and established correlation of heavy metals between healthy persons and HCV patients. Atomic absorption spectrophotometer (AAS) was used to explore them. Concentrations of heavy metal in different samples (blood serum, nails and hair) of patients and healthy individuals. Result revealed that heavy metals (Lead, Cobalt, Cadmium, Manganese, Iron and Cooper) concentration were significantly higher in blood of HCV patients as compared to normal persons, but some metals like Ni and Zn were present in normal concentration and in low concentration respectively. After chelation with monoisoamyl DMSA (MiADMSA) a significant amount of heavy metals was excreted in the urine in a dose dependent manner. It was generally observed from the results that TDS is a better treatment option than BD for chelation of heavy metals in hepatitis c virus patients. This chelation therapy will be helpful to reverse the HCV related health problems.

Hiyama cross-coupling is a versatile reaction in synthetic organic chemistry for the construction of carbon–carbon bonds. It involves the coupling of organosilicons with organic halides using transition metal catalysts in good yields and high enantioselectivities. In recent years, hectic progress has been made by researchers toward the synthesis of diversified natural products and pharmaceutical drugs using the Hiyama coupling reaction. This review emphasizes the recent synthetic developments and applications of Hiyama cross-coupling.

Abstract Plant based protein sources are one of the best, cost effective and easily available protein sources being used in fish feed. But due to a lower number of micro-biota in fish gut plant meal based diets cannot be digested and absorbed well in fish body. Probiotics were supplemented at 0, 1, 2, 3, 4 and 5 gkg-1 levels in fish feed for formulating one control and five test diets. In this study, three replicates of each treatment were used and number of fingerlings was 15 in each replicate. The C. carpio (common carp) fingerlings were fed at 5% of live wet weight on their prescribed diet twice daily. The results revealed that supplementation of probiotics in corn gluten meal based diets significantly (p

The present study was designed to estimate the zinc (Zn) requirement of Labeo rohita juveniles fed practical diet. Treatments used for the study were consisted of six experimental diets supplemented with graded levels of Zn (0, 21, 42, 63, 84 and 104 mg/kg diet) from Zn gluconate. For each experimental diet, two replicates were allocated, and 18 fish were stocked in each replicate. The feeding trial was lasted for 90 days. Results showed that final weight, absolute weight gain, weight gain% and specific growth rate increased with increasing dietary Zn levels up to 42 mg/kg and started to decrease with further increase in dietary Zn level. Quadratic regression analysis of weight gain% data indicated that L. rohita juveniles required 62.58 mg/kg Zn for normal growth. Maximum Zn absorption was observed in fish fed diet supplemented with 42 mg/kg Zn compared with other dietary treatments. Alkaline Phosphatase (ALP) activity in kidney and spleen of L. rohita juveniles increased with the increase in dietary Zn levels up to 42 and 63 mg/kg, respectively. Conclusively, supplementation of graded levels of dietary Zn-gluconate improved the growth performance and increased the Zn bioavailability and ALP activity up to a certain limit in L. rohita juveniles.

This review highlights the underexplored potential and promises of marine bioactive peptides (MBPs) with unique structural, physicochemical, and biological activities to fight against the current and future human pathologies. A particular focus is given to the marine environment as a significant source to obtain or extract high-value MBPs from touched/untouched sources. For instance, marine microorganisms, including microalgae, bacteria, fungi, and marine polysaccharides, are considered prolific sources of amino acids at large, and peptides/polypeptides in particular, with fundamental structural sequence and functional entities of a carboxyl group, amine, hydrogen, and a variety of R groups. Thus, MBPs with tunable features, both structural and functional entities, along with bioactive traits of clinical and therapeutic value, are of ultimate interest to reinforce biomedical settings in the 21st century. On the other front, as the largest biome globally, the marine biome is the so-called “epitome of untouched or underexploited natural resources” and a considerable source with significant potentialities. Therefore, considering their biological and biomedical importance, researchers around the globe are redirecting and/or regaining their interests in valorizing the marine biome-based MBPs. This review focuses on the widespread bioactivities of MBPs, FDA-approved MBPs in the market, sustainable development goals (SDGs), and legislation to valorize marine biome to underlying the impact role of bioactive elements with the related pathways. Finally, a detailed overview of current challenges, conclusions, and future perspectives is also given to satisfy the stimulating demands of the pharmaceutical sector of the modern world.

Abstract Background Stevia (Stevia rebaudiana Bertoni) natural, safe, non-toxic, non-caloric sugar substitute is rich source of pharmacologically important glycoside stevioside that is linked to the pathology and complications of hyperlipidemia. Methods The present research was carried out to explore the anti-hyperlipidemic effect of aqueous extract of Stevia rebaudiana Bertoni leaves in albino rats. For this purpose, hyperlipidemia was induced by administration of Cholesterol (90% E, Appli Chem, Darmstadt, Germany) mixed at dose of 400 mg/kg body weight of rats in their daily routine feed. The hyperlipidemic rats were administered with aqueous stevia extract at different dose levels (200, 300, 400 and 500 ppm/kg b.w.) for 8 weeks; the control rats were fed basal diet during this period. Ethical approval for the current research was obtained from Institutional Review Board Faculty of Science & Technology Government College University, Faisalabad, Pakistan. Results Stevia aqueous extract decreased the body weight gain by lowering the feed intake of hyperlipidemic rats. Furthermore, administration of stevia extract at different levels significantly (P

Abstract Background In recent times, focus on plant research has improved all over the world and essential parts of plants provide bioactive compounds in human diet. The bael (Aegle marmelos) has enormous traditional uses in the treatment of chronic diarrhea, dysentery, peptic ulcers and as a laxative. The main focus of this study was characterization of bael leaf extract for its bioactive constituents, antihypercholestrolemic and antilipidemic perspectives. Methods After proximate composition of bael powder, the aqueous extract of bael leaf was used for phytochemical profiling (alkaloids, total phenolic content and total flavonoid content). Afterwards, normal rats group G0 was administrated basal diet while G1 and G2 normal rat groups were fed diets containing bael leaf extract 125 mg and 250 mg, respectively for consecutive 60 days. In a similar way, hyperlipidemic rats group Gh0 was administrated basal diet while Gh1 and Gh2 hyperlipidemic rat groups were fed diets containing bael leaf extract 125 mg and 250 mg, respectively for consecutive 60 days. The blood drawn on day 0, day 30 and day 60 was analyzed for serum parameters, such as total cholesterol, high-density lipoprotein cholesterol, low–density lipoprotein cholesterol, triglycerides concentration and free and ester cholesterol. Results Bael leaf powder is a rich source of crude fiber (14.50 ± 0.10 g/100 g). Aqueous extract of bael leaf contains alkaloids (15.58 ± 0.05 mg/g), flavonoids (64.00 ± 0.05 mg/g), phenolics (30.34 ± 0.01 GAEmg/g). From the In vivo studies, the lowest weight gain was observed in group G2 and in Gh2 as compared to control of both groups. The decrease in serum TC for G1–15.06%, G2–17.27% while in Gh1–22.46% and Gh2–34.82% after day 60, respectively. The maximum decrease was observed in group G2 (− 14.33%) and in Gh2 (− 24.79%) for triglycerides after 60 days. For HDL-cholesterol, significant increase (11.20%) in G2 and (49.83%) in Gh2 was observed of after 60 days. A trend in decrease of serum LDL–cholesterol in G2 (− 9.63%) and in Gh2 (− 44.65%) was also observed at day 60, and − 19.05% and − 30.06% decrease was noted in G2 and Gh2, respectively and decreasing trend was observed in free and total cholesterol − 22.30% and − 81.49% for groups G2 and Gh2 after day 60. Conclusions The results of the present study demonstrated that the extract contents of bael leaf provide protective role against hypercholesterolemic and hyperlipidemic conditions.

The present study was conducted to investigate the effects of Cuscuta reflexa extract (CRE) on the activities of germination enzymes, seed germination vigor, biomass production, physio-biochemical attributes, and seed yield of water-stressed wheat plants. Different levels of CRE (0, 10, 20, 30, 40, and 50%), including water soaking, were used as seed priming. Water stress negatively affected the seed germination, germination enzyme activities, growth, yield, and different physio-biochemical attributes of wheat plants. Low doses of CRE (10, 20, and 30%) ameliorated the adverse effects of water stress on seed germination attributes, and activities of germination enzymes, but negative impacts were recorded at higher doses (40 and 50%) of CRE. Water-stressed wheat plants grown from seeds pre-treated with low doses of CRE also showed better growth and yield as compared with non-treated ones, and that was associated with an improvement in water relations, photosynthetic pigments, nutrient acquisition, reduced lipid peroxidation, and better antioxidative defense mechanisms. The maximum increase in seed yield was 14.77 and 12.32%, found in plants grown from seeds treated with 20% and 10% CRE, respectively. In conclusion, it is suggested that using low doses of CRE as seed priming can contribute to better wheat yield under water stress, especially in semi-arid and arid areas.

The physico-chemical characterization of the surface water. Samples was carried out collected from nine sampling points of drain passing by the territory of Hafizabad city, Punjab, Pakistan. The water of drain is used by farmers for irrigation purposes in nearby agricultural fields. Twenty water quality parameters were evaluated in three turns and the results obtained were compared with the National Environmental Quality Standards (NEQS) municipal and industrial effluents prescribed limits. The highly significant difference (p0.05) was noted for temperature, pH, electrical conductivity, hardness, calcium, sodium, chemical oxygen demand and chloride among water samples from different sampling points. Furthermore, the experimental results of different water quality parameters studied at nine sampling points of the drain were used and interpolated in ArcGIS 9.3 environment system using kriging techniques to obtain calculated values for the remaining locations of the Drain.
