because of on-call responsibilities, many medical residents are subjected to chronic partial sleep deprivation, a form of sleep restriction whereby individuals have chronic patterns of insufficient sleep. it is unclear whether deterioration in cognitive processing skills due to chronic partial sleep deprivation among medical residents would influence educational exposure or patient safety.twent...

  Background & Objective: Social inequality and deprivation is strongly related to basic health status in different societies. Individuals with lower socioeconomic status (SES) experience higher rate of mortality and lower level of life expectancy. Although health status is affected by poverty, but the precise pathways that link socioeconomic status and health remain unclear. The aim of the pre...

Background and Aims: It is well-recognized that endogenous opioidergic system plays an important role in pain sensitivity, pain perception, and response to some stressing situations. The present study examined the probable role of endogenous opioidergic system in effects of food deprivation on formalin-induced nociceptive behaviors in male and female rats. Methods: To make short-term food d...

The compensatory growth, proximate composition and amino acid contents changes of young yellow catfish (Pelteobagrus fulvidraco R.) (1.63-1.69 g) had been investigated using a 45-day cyclic feed deprivation and re-feeding experiment. The control group (S0) was fed daily with live tubificid worms (Limnodrilus hoffmeisteri), while the S1/4, S1/2, and S1/1 groups cyclically experienced one-day of ...

Abstract Background: Nowadays, working long hours and shift work are inevitable, even though these working schedules are associated with several physical and mental effects. Gastrointestinal complaints are common among their physical effects. Recent studies have shown organoprotective effect of melatonin in gastrointestinal tract. In this study we investigated gastric mucosal damage due to par...

This study examines whether German and Portuguese fiveto six-, and eightto nine-year-old children distinguish between the feelings attributed to a victimizer or to themselves if they were the victimizers in two hypothetical moral violations (stealing and breaking a promise), and how they morally evaluate the emotions they attribute to victimizers and the person of the victimizer. The results sh...

Homeothermic animals regulate body temperature (T(b)) by using both autonomic and behavioral mechanisms. In the latter process, animals seek out cooler or warmer places when they are exposed to excessively hot or cold environments. Thermoregulation is affected by the state of energy reserves in the body. In the present study, we examine the effects of 4-day food deprivation on circadian changes...

Neural information processing entails a high energetic cost, but its maintenance is crucial for animal survival. However, the brain's energy conservation strategies are incompletely understood. Employing functional brain-wide imaging and quantitative behavioral assays, we describe a neuronal strategy in Caenorhabditis elegans that balances energy availability and expenditure. Upon acute food de...

The course of repletion and the effects of food deprivation on meal size were explored in three experiments on larvae of Chrysopa carnea (Neuroptera). Feeding to repletion was found to occur within the first 30 min of exposure to food. Meal size increased as an ogival function of deprivation, up to the limit of gut capacity. Behavioral components involved in the initiation of feeding were littl...

Homeostatic mechanisms stabilize neural circuit function by keeping firing rates within a set-point range, but whether this process is gated by brain state is unknown. Here, we monitored firing rate homeostasis in individual visual cortical neurons in freely behaving rats as they cycled between sleep and wake states. When neuronal firing rates were perturbed by visual deprivation, they graduall...
