The physiological mechanisms underlying the 'cost of reproduction' remain under debate, though oxidative stress has emerged as a potential candidate. The 'oxidative cost of reproduction' has received considerable attention with regards to food and antioxidant availability; however, the limitation of water availability has thus far been neglected. In this study, we experimentally examined the co...

Evidence in rats suggests that central oxytocin (OT) signaling pathways contribute to suppression of food intake during dehydration (i.e., dehydration anorexia). The present study examined water deprivation-induced dehydration anorexia in wild-type and OT -/- mice. Mice were deprived of food alone (fasted, euhydrated) or were deprived of both food and water (fasted, dehydrated) for 18 h overnig...

based on both animal and human studies, inequality in food intake and social instability has adverse effects on the health of individuals and the community. however, it is not known whether social instability, food deprivation and food inequality affect neuronal death and premature aging in young animals. to address this question, the effects of these adverse situations, histopathological chang...

Besides other physiological functions, adenosine-5'-triphosphate (ATP) is also a neurotransmitter that acts on purinergic receptors. In spite of the presence of purinergic receptors in forebrain areas involved with fluid-electrolyte balance, the effect of ATP on water intake has not been investigated. Therefore, we studied the effects of intracerebroventricular (icv) injections of ATP (100, 200...

climate change around the world is now a reality that has adverse effects on the environment and human health. there is little information about the effect of climate change on food systems, especially seafood from the farm to the table. the aim of this study was to review the fundamental effects of climate change on seafood safety and human health. climate change is expected to increase chemic...

Introduction: Several reports show a relationship between health equity, and health status and longevity of individuals. In this study, effects of food deprivation, inequality and social instability were investigated on the formation of lipofuscin pigment in Balb/C mice by histopathological and biochemical methods. Methods: Thirty-six male mice were divided into 6 groups, then different kind...

Twelve rats were food-deprived to 90% or 70% of their free-feeding weights. Food pellets were then delivered every 60 s (Fixed Time 60-s schedule), and the development of adjunctive drinking was measured by the water consumed and the number of licks. For "master" rats, each lick was followed by 10-s delays in food delivery. Yoked control rats received food at the same time as their master rats ...

as cost of living rises and people’s wages / salaries do not cover their basic food and dietary needs, interest in parttime farming has risen. part-time farming activities are being practiced by different people as a food security strategy from vulnerable households. but these part-time farms have had limited success in providing food/nutrition security, increasing incomes and improving well-be...

introduction: based on human studies, inequality and social injustice have adverse effects on the individual and community health. in this study, the effects of food intake inequality and social status changes on pain perception and immunological factors were investigated in balb/c mice. methods: the present study was conducted by implementing different social stresses including food deprivatio...
