piriformospora indica, a cultivable root colonizing endophytic fungus of sebacinales, promotes plant growth and confers resistance against biotic and abiotic stress. the fungus has also the ability to colonize the roots of many varieties of plant species. the goal of present study was to clarify the colonization ability of p.indica in artichoke roots and the respond of plant to water stress. re...

introduction: different mechanisms are involved in stress induced analgesia (sia) and hyperalgesia (sih). repeated stress induces development of tolerance to sia. the role of hpa axis and gs signaling pathway in these effects are investigated in the current study. methods: forced swim stress (5 min/day) in water (20±1 ºc) was employed to adult male wistar rats (200-250 g). the nociceptive thres...

documented war experiences have provided early descriptions of different group of psychiatric features. a combat soldier with palpitation and chest pains was felt to have a functional cardiac disturbance, called soldier's heart. anxiety and other symptoms indicating increased arousal were called shell shock and were thought to be related to lesions in the central nervous system (cns). desc...

two glasshouse and field experiments were conducted to assess the effects of root system, water uptake, water use efficiency and early vigor on yield and drought tolerance of bread wheat in two successive farming seasons (2009-11). the experiments were conducted as randomized complete block design and two-year results analyzed as combined design. considerable genetic variation was observed amon...

the aim of this study was to investigate the effect of acute swimming stress on plasma corticosterone and leptin levels in female and male rats. thirty- seven adult male (n=20) and female (n=20) sprague dawley rats (200-250 g weight) were used. the leptin and corticosterone levels were measured following swimming stress (10 minutes) or no stress. plasma leptin and corticosterone were measured b...

high weissenberg boundary layer flow of viscoelastic fluids on a stretching surface has been studied. the flow is considered to be steady and two dimensional. flows of viscoelastic liquids at high weissenberg number exhibit stress boundary layers near walls. these boundary layers are caused by the memory of the fluid. upon proper scaling and by means of an exact similarity transformation, the n...

drought is a major limiting factor for agricultural production in most parts of the world and landraces areimportant genetic resources for crop improvement in dry areas. during the 2007-2008 cropping season, 23 chickpea (cicer arietinum l.) genotypes consisting of 21 kabuli chickpea landraces provided by the national plant gene bank of iran and two known commercial varieties (hashem and arman) ...

background: development of the central nervous system (cns) is dependent on interactions between genetic and epigenetic factors, some of which could affect the susceptibility of the developing brain to damaging insults. gestational stress has been shown as a potential factor associated with higher risk of developing certain neurological and psychiatric disorders. this study tested the hypothesi...
