osmotic stress is one of the major factors that significantly reduce yields in dry areas. plants respond to this abiotic stress at physiological and molecular levels. many genes are induced under stress conditions by transcription factors. dehydration responsive element binding (dreb) protein is a subfamily of ap2/erf transcription factors which control expression of many osmotic stress-inducib...

-Theoretical constraints on the stress-dilation relation for a deforming Coulomb material require v -< 0 if C = 0 and v -< sin-l(Tm/e,n) always, where v is the dilation angle, 0 is the friction angle, C is cohesion, z,, is the maximum shear stress, and a,~ is the mean effective stress. Recent laboratory measurements of friction and dilatancy of simulated fault gouge show that small amplitude sh...

in order to evaluate the best drought resistance indices in sugar beetgenotypes, an experiment was conducted in 2002 using a split- plot design within randomized complete block design with three replications at the research farm, shiraz-zarghan. the main plots consisted of three irrigated regimes: non stress, 75% (mid stress) and 50% (intense stress) non stress and the ten genotypes as the sub ...

When a physiological (exercise) stress echo is scheduled, interest focuses on wall motion segmental contraction abnormalities to diagnose ischemic response to stress, and on left ventricular ejection fraction to assess contractile reserve. Echocardiographic evaluation of volumes (plus standard assessment of heart rate and blood pressure) is ideally suited for the quantitative and accurate calcu...

IMPORTANCE Animal data suggest that chronic stress is associated with a reduction in norepinephrine transporter (NET) availability in the locus coeruleus. However, it is unclear whether such models are relevant to posttraumatic stress disorder (PTSD), which has been linked to noradrenergic dysfunction in humans. OBJECTIVES To use positron emission tomography and the radioligand [11C]methylreb...

in order to study stress tolerance indices and identifying tolerance genotypes to drought stress condition 16 genotypes of durum wheat were assessed in a randomized complete block design with four replications under two irrigated and rainfed conditions in the research station located in west of iran ilam in 2006- 2007. results showed that variation in among durum wheat genotypes under irrigated...

objectives: small dense low‑density lipoprotein (sdldl) which has a small ldl particle size with greater susceptibility to oxidation is regarded as a risk marker for cardiovascular disease. the diacron reactive oxygen metabolites (d‑roms) test has recently been introduced as an oxidative stress‑related marker in the clinic. the aim of the present study was to investigate the correlation between...

UNLABELLED Although the burden of hepatocellular carcinoma (HCC) is an escalating public health problem, it has not been rigorously estimated within a Canadian context. We conducted a population-based study using Ontario Cancer Registry linked administrative data. The mean net costs of care due to HCC were estimated using a phase of care approach and generalized estimating equations. Using an i...

     Improved drought-tolerant maize hybrids would significantly reduce water consumption and increase yield in arid environments. Our knowledge about genetic parameters is very essential before starting a successful breeding program. The present research was carried out throughout three successive years between 2013-15 to reveal the pattern of inheritance in yield, yield-components and related...
