To investigate the lignification process and its physiological significance under drought-stressed conditions, the changes in enzymes responsible for lignification and the related physiological parameters were determined in white clover (Trifolium repens L.) leaves during 28 d of water deficit treatment. Water deficit gradually decreased leaf water potential (Psiw) to -2.33 MPa at day 28. For t...

Stress and episodic memory impairment have previously been associated. Acute stress disorder (ASD) is a maladaptive stress response, which develops in some individuals following traumatic life events. Recently, the authors demonstrated a specific deficit in associative memory for emotionally neutral stimuli in ASD and posttraumatic stress disorder (PTSD). This study further tested the relations...

AIMS High relapse rate and extreme difficulty to maintain abstinence are core characteristics of alcohol dependence (AD). Previous studies have demonstrated a persistent decision-making (DM) deficit in AD. We aimed to reveal specific personality features and stress-coping mechanisms presumed to compensate for ineffective DM skills. METHODS Eighty-eight unmedicated patients with AD were enroll...

in order to study of water deficit effects on yield and some vegetative aspects of cotton, 30 cotton genotypes evaluated in 2014 summer at garmsar agricultural research station in greenhouse and field conditions. the experimental design was split plot based on a completely randomized blocks with three replications. six superior genotypes including k8801, k8802, avengard, varamin, khordad and qu...

Cellular water-deficit stress triggers many changes in gene expression which can be used to define the response of a plant to an environmental condition. Microarray technology permits the study of expression patterns of thousands of genes simultaneously, permitting a comprehensive understanding of the types and quantities of RNAs that are present in a cell in response to water-deficit stress. T...

Thermal imaging has been used in the past for remote detection of regions of canopy showing symptoms of stress, including water deficit stress. Stress indices derived from thermal images have been used as an indicator of canopy water status, but these depend on the choice of reference surfaces and environmental conditions and can be confounded by variations in complex canopy structure. Therefor...

It has been reported that social isolation stress could be a key factor that leads to cognitive deficit for both humans and rodent models. However, detailed mechanisms are not yet clear. ADAR1 (Adenosine deaminase acting on RNA) is an enzyme involved in RNA editing that has a close relation to cognitive function. We have hypothesized that social isolation stress may impact the expression of ADA...
