In this context, it is necessary to select and develop salt-tolerant genotypes that can grow in salty soils have high yields, formulate strategies which may enhance the plant survival under salinity stress. Melatonin (N-acetyl-5-methoxytryptamine) an important biological hormone provides resistance abiotic stress conditions be secreted by plants. concentration plants varies depending on genotyp...

Plant responses to salt and water stress have much in common. Salinity reduces the ability of plants to take up water, and this quickly causes reductions in growth rate, along with a suite of metabolic changes identical to those caused by water stress. The initial reduction in shoot growth is probably due to hormonal signals generated by the roots. There may be salt-specific effects that later ...

ratios of insulin to glucagon (I/G) from 14E to 17E ranged from 1.8 to 2.2 which were significantly greater than normal I/G ratio in the postabsorptive state in avian species (1.2-1.7). The results indicate that insulin is an important promoter of chick embryo growth by anabolic drive to promote protein deposition especially during the embryonic rapid growth period. There also was a significant...

anxiety is one of the prevalent mental health disorders. stressors by changes in physiology can increase risk of physical diseases. high levels of cortisol have many negative effects on health. this study aimed to determine anxiety symptoms prevalence and its relationships with plasma cortisol level. this study was a descriptive- analytical cross-sectional that was conducted on 100 nursing stud...

Oxidative stress-the production and accumulation of reduced oxygen intermediates such as superoxide radicals, singlet oxygen, hydrogen peroxide, and hydroxyl radicals-can damage lipids, proteins, and DNA. Many disease processes of clinical interest and the aging process involve oxidative stress in their underlying etiology. The production of reactive oxygen species is also prevalent in the worl...

Exposure to chronic stress is a reliable predictor of depressive disorders, and social stress is a common ethologically relevant stressor in both animals and humans. However, many animal models of depression were developed in males and are not applicable or effective in studies of postpartum females. Recent studies have reported significant effects of chronic social stress during lactation, an ...

Many Australian marsupials are threatened species. In order to manage in situ and ex situ populations effectively, it is important to understand how marsupials respond to threats. Stress physiology (the study of the response of animals to challenging stimuli), a key approach in conservation physiology, can be used to characterize the physiological response of wildlife to threats. We reviewed th...
