introduction: peripheral vascular disease (pvd) is a major cause of morbidity and is associated with coronary artery disease (cad). we aimed to perform lower limb perfusion scan (llps) in patients referred for myocardial perfusion imaging (mpi) and estimate prevalence of pvd in subgroups with normal and abnormal mpi results. we also compared quantitative indices of llps in patients with and wit...

original article   introduction: exposure to heat is one of the workplace risk factors, which may lead to thermal strain, such as rising heart rate and body temperature. to have the best association between a heat stress indices and physiological parameters have always been a major concern for those studying the subject. this study aims to compare the association of two heat stress indices with...

Wheat improvement for drought tolerance requires reliable assessment of drought tolerance variability among segregating populations. One hundred and fifty-one F3 and F4 families of durum wheat derived from a cross between Oste-Gata (as drought tolerance) and Massara-1 (as susceptible) genotypes were evaluated both under moisture stress (E1) and non-stress (E2) field environments using a randomi...

abstract: evaluation of drought tolerance for 20 barley genotypes were conducted under normal irrigation and terminal stress condition by withholding irrigation at the time of 50% flowering. drought effect on grain yield and plant total mass traits was studied and eight of stress indices including stress tolerance index (sti), stress tolerance (tol), stress susceptibility index (ssi), mean prod...

in order to study of sodium nitroprusside(snp) application effect on growth indices and water use efficiency of kidney beans cultivars(akhtar and derakhshan) under water deficit stress, an experiment was conducted in split factorial based in randomized complete block design with three replications in bu-ali sina university research field at 2012. water stress treatments included vegetative stre...

inheritance of several yield-based drought resistance indices was studied by a halfdiallel method using seven winter wheat varieties. the parental lines were such chosen as to represent a broad range of drought stress resistance. the experiment was conducted in a split-plot design at the research farm, faculty of agriculture, zanjan university, iran, in 1998. irrigated vs. rainfed regimes w...
