Diabetes as a stress response he origin of adult-onset diabetes may be a counterproductive stress reaction in the endoplasmic reticulum (ER), according to Umut Özcan, Gökhan Hotamisligil (Harvard School of Public Health, Boston, MA), and colleagues. Type II or adult-onset diabetes has remained a mystery because the body seemingly acts against its own interests. As caloric intake and obesity ris...

The ability of a cell, tissue, or organism to better resist stress damage by prior exposure to a lesser amount of stress is known as adaptive response. It is observed in all organisms in response to a number of different cytotoxic agents. One of these agents, oxidative stress, is known to induce an adaptive response in bacteria that is accompanied by the induction of many proteins. De novo prot...

vicia sativa l., an annual winter growing leguminous plant, is a valuable source of protein and minerals for cattle. drought is one of the key stress factors that influence plant growth and development. in order to investigate common vetch physiological and molecular responses under normal irrigation (n) and two levels of drought stress [s1= 30% and s2= 10% field capacity (fc)], a greenhouse exp...

The main purpose of this paper has been to discuss the effects of psychological stress and other environmental factors on incidence of diseases. We were specifically concerned with stress that increased susceptibility of uninfected hosts when exposed to infection. If such stresses also reduced resources, fecundity and/or survivorship, there was a reduction in the host carrying capacity. In addi...

Members of the 14-3-3 protein family are involved in many important cellular events, including stress response, survival and apoptosis. Genes of the 14-3-3 family are conserved from plants to humans, and some members are responsive to UV radiation. Despite the high rate of pollution generated by nano-pollutants, up to now is totally obscure their toxic effect on development. Embryos treated wit...

Stress effects on memory are well-known. Most studies, however, focused on the impact of stress on hippocampus-dependent 'declarative' memory processes. Less is known about whether stress influences also striatum-based memory processes, such as stimulus-response (S-R) memory. First evidence from rodent experiments shows that glucocorticoid stress hormones may enhance the consolidation of S-R me...

Psychiatric disorders are known to result from a strong interaction between genetic predisposition and environmental factors, mainly exposure to stressful events. Environmental events can modulate genes expression, possibly via epigenetic mechanisms, and affect onset/ expression of a disease [1]. Epigenetic mechanisms include, among others, post-transcriptional regulation by non-coding RNAs suc...

This paper presents a study on the frequency response of a capacitive micro-beam resonator under various applied stresses. The governing equation whose solution holds the answer to all our questions about the mechanical behavior is the nonlinear electrostatic equation. Due to the nonlinearity and complexity of the derived equation analytical solution are not generally available; therefore, the ...
