Many ovarian cancer cells express stress-related molecule MICA/B on their surface that is recognized by Vγ2Vδ2 T cells through their NKG2D receptor, which is transmitted to downstream stress-signaling pathway. However, it is yet to be established how Vγ2Vδ2 T cell-mediated recognition of MICA/B signal is transmitted to downstream stress-related molecules. Identifying targeted molecules would be...

[1] We estimate the rate of aftershocks triggered by a heterogeneous stress change, using the rate-and-state model of Dieterich. We show that an exponential stress distribution Pt(t) exp( t/t0) gives an Omori law decay of aftershocks with time 1/t, with an exponent p = 1 Asn/t0, where A is a parameter of the rate-and-state friction law and sn is the normal stress. Omori exponent p thus decrease...

background: occupational stress occurs when job needs do not comply with the abilities, support, and needs of the employee. in addition to negatively affecting the physical and mental health of individuals, occupational stress can reduce their efficiency and productivity in organizations. this paper investigated the rate of job stress and its relation to absenteeism in workers. methods: in this...

Cells from patients with the autosomal recessive disorder ataxia-telangiectasia (A-T) display accelerated telomere shortening upon culture in vitro. It has been suggested that A-T cells are in a chronic state of oxidative stress, which could contribute to their enhanced telomere shortening. In order to examine this hypothesis, we monitored the changes in telomere length in A-T homozygous, heter...

PURPOSE Organizations have raised concerns regarding stress in the medical work environment and effects on health care worker performance. This study's objective was to assess workplace stress among interns, residents, and attending physicians using Ecological Momentary Assessment technology, the gold-standard method for real-time measurement of psychological characteristics. METHOD The autho...

terminal heat stress is the most widespread heat stress in the world. in order to evaluate the effect of heat stress on yield, yield component, and mopho-phenological traits of barley, 10 barley genotypes including the 2-row genotypes: mahour, khoram, nimrooz, abidar and 6-row genotypes: yousef, rihan 03, izeh, zahak, nosrat, jonoub were tested under normal (optimum sowing date) and heat stress...

BACKGROUND Cardiac resynchronisation therapy improves peak oxygen uptake (peak VO(2)) 3-9 months after device implantation. In chronic heart failure, total isovolumic time (t-IVT) is a major determinant of peak VO(2) and of cardiac output at peak dobutamine stress. In selected patients, resynchronisation can instantaneously shorten t-IVT. We sought to determine the acute effect of resynchronisa...
