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.

Background. Addiction is a multifaceted brain disorder characterized by compulsive substance use despite harmful consequences. The physiological effects of drugs, such as amphetamines and captagon, on organ functions remain a significant concern, with varying impacts based on substance type and duration of use. Aim of study. This study aimed to investigate the impact of amphetamine and captagon abuse on liver and kidney functions. By comparing physiological parameters between individuals with substance abuse history and a control group, the study sought to elucidate the health implications of long-term drug use. Methods. The study involved 50 participants: 30 with a history of substance abuse and 20 healthy controls. It assessed liver and kidney functions using biochemical and ELISA tests to measure AST, ALT, ALP, Total Serum Bilirubin, Serum Albumin, Serum Creatinine, and Blood Urea. Results. The study revealed a significant difference between drug users and controls, with drug users exhibiting higher levels of urea and serum creatinine. Liver function tests showed increased GOT, GPT and ALP levels in drug users. Furthermore, total serum bilirubin was significantly higher in drug users, indicating liver impairment. Age-related analysis showed more severe renal and liver dysfunction in older drug users, with notable increases in urea and serum creatinine levels with age (p=0.001 and p=0.009, respectively). Conclusion. Both amphetamines and captagon pose a significant health risk to renal and liver functions. This underscores the need for awareness and interventions targeted at mitigating the health implications of substance abuse, highlighting the importance of continuous monitoring and treatment strategies for affected individuals.

The Quorum sensing (QS) system is a widely existing communication mechanism, which regulates bacterial community behaviors and the expression of specific genes. The most common pathogenic bacteria in clinical infections are gram-negative bacteria, and QS plays an important regulatory role in the production of virulence factors and development of antibiotic resistance. This article reviews the QS systems of gram-negative bacteria and provides an overview of how they regulate their physiological functions., Competing Interests: The authors declare that they have no competing interests., (© 2024 Chu and Yang.)

Environment imposes physiological constraints which are life-stage specific as growth-maintenance and/or growth-reproduction energetic requirements are size and volume-dependent. The scallop Argopecten purpuratus, one of the most important bivalve species subjected to fishery and aquaculture along the Humboldt Current System, inhabits spaces affected by continuous changes in temperature, pH, oxygen, and food availability driven by remote and local oceanographic processes. Specifically, in Chile, this species is mainly cultured in central-north Chile where is permanently affected by upwelling events of dissimilar intensity and duration which generate local conditions of acidification, deoxygenation, and cooling with different magnitudes. However, to date, it remains unknown how this economic valuable resource is physiologically affected throughout its life cycle by the continuous environmental changes driven by upwelling events of different intensities and duration along the year. Here, for the first time, A. purpuratus life-stage physiological sensitivity was assessed at a seasonal scale through a year-field experiment where growth, calcification, and survivorship were evaluated. Our study shows how seasonal differences in the upwelling phenology (here measured as changes in temperature, dissolved oxygen, pH, and primary productivity, but also as the number, duration, and intensity of cooling and de-oxygenation events) notably impacted the A. purpuratus physiological performance from juvenile to adult life-stages. This was especially noticeable during the spring season which showed the most intense cooling and deoxygenation events driven by stronger favorable-upwelling winds and the lowest growth and gross calcification rates (the highest decalcification rates) where adult stages showed the lowest performance. On the other hand, A. purpuratus survivorship was not significantly affected by upwelling intensity which would be providing evidence of the high physiological flexibility and well-locally adapted is this species to fluctuating and occasional stressful environmental conditions. Our results are significantly relevant in the climate change context as some upwelling systems are at risk to change shortly (i.e., an upwelling intensification in frequency and intensity) as a consequence of changes in the atmospheric pressures that modulate favourable-upwelling winds. These changes may certainly increase the climate related-risks of the entire socio-ecological systems related to the fishery and aquaculture of A. purpuratus along the Humboldt Current System.

An obvious characteristic of computer games is stress, competition, and physiological alterations in the body. It is regarded as an important subject including those factors in e-sports, getting progressively popular in the digital era. The psychological and physiological impacts of e-sports, conducted in a competitive ambiance, on the body and mind over the course of competitions are not yet known. The aim of the paper is determining the impacts of players performing in e-sports games on some biochemical and hormonal factors shaped in the body during the game. In the group of research, there are twenty electronic sports volunteer players playing in e-sports games. Samples are gathered from the players in the study thirty minutes before and after electronic sports games. Given the results, it is concluded that e-sports players' ACTH, cortisol, and testosterone levels rose substantially.

Itaconic acid (IA) is an economically important platform chemical, which finds wide applications in chemical industry and agriculture. This study attempted to ascertain the influence of IA on crop seedlings. Four crops including maize, cucumber, sorghum and wheat were grown in hydroponics containing Hoagland's nutrient solution and one of serially diluted IA. The biomass, the activities of antioxidant enzymes and the content of chlorophyll and malondialdehyde (MDA) in seedlings were investigated. Results showed that low concentration of IA (≤200 mg L-1) benefited crop growth and alleviated oxidative stress, as it not only improved biomass, leaf area, chlorophyll content, the activities of catalase (CAT) and peroxidase (POD), but also reduced the formation of MDA and the activities of ascorbate peroxidase (APX) and superoxide dismutase (SOD). IA exerted different physiological and antioxidant influences on crops. The physiological impacts of IA on crops in descending order are cucumber > wheat > maize > sorghum. Overall, IA stimulated crop growth through affecting biochemical components such as antioxidant enzymes and chlorophyll. This study provides the basis for future use of IA as a fertilizer.

Abstract The toxicity and kinetic uptake potential of zinc oxide (ZnO) and titanium dioxide (TiO 2) nanomaterials into the red bean (Vigna angularis) plant were investigated. The results obtained revealed that ZnO, due to its high dissolution and strong binding capacity, readily accumulated in the root tissues and significantly inhibited the physiological activity of the plant. However, TiO 2 had a positive effect on plant physiology, resulting in promoted growth. The results of biochemical experiments implied that ZnO, through the generation of oxidative stress, significantly reduced the chlorophyll content, carotenoids and activity of stress-controlling enzymes. On the contrary, no negative biochemical impact was observed in plants treated with TiO 2. For the kinetic uptake and transport study, we designed two exposure systems in which ZnO and TiO 2 were exposed to red bean seedlings individually or in a mixture approach. The results showed that in single metal oxide treatments, the uptake and transport increased with increasing exposure period from one week to three weeks. However, in the metal oxide co-exposure treatment, due to complexation and competition among the particles, the uptake and transport were remarkably decreased. This suggested that the kinetic transport pattern of the metal oxide mixtures varied compared to those of its individual constituents. Graphical abstract Image 1 [ABSTRACT FROM AUTHOR]

Kangaroo mother care (KMC) involves placing the newborn infant into prolonged and continuous skin-to-skin contact with the mother as soon as possible after birth, exclusive breastfeeding, early discharge from the health facility, and supportive follow-up at home. Claimed benefits of KMC as an aid to the clinical mitigation of some detrimental features of prematurity need to be evidence based. This article, the first of two, provides an overview of the impact of prematurity on those features of neonates to which KMC may be directed. Specifically, the mitigation of some cardiorespiratory, neurophysiological, sensory, gastrointestinal, musculoskeletal, renal, metabolic, and immunological impacts are outlined. Relevant neurobehavioral, psychosocial, sociocultural, and economic perspectives are briefly reviewed in the companion article. These two articles provide scientific support for a wider upscaling of KMC education and its cautious use in physiologically stable preterm infants. [ABSTRACT FROM AUTHOR]
