background: pre-eclampsia, a vascular disorder of pregnancy, is a leading cause of maternal morbidity as well as perinatal morbidity and mortality. the cause of pre-eclampsia remains largely unknown. accumulating evidences from clinical and epidemiological studies suggest that diffuse endothelial dysfunction, resulting from oxidative stress, plays an important role in the pathogenesis of pre-ec...

abstract background and objective : psychological aspects of chronic diseases has attracted many professionals. because the incidence of sudden and uncontrollable symptoms of many diseases, causing stress and create a variety of negative emotions and mood in patients'. the purpose of this study was to investigate the effectiveness of group reality therapy in reduceing stress, anxiety and depres...

OBJECTIVE The aim of this study was to investigate the effect of pre-treatment with curcumin on metabolic changes induced by two different pathophysiological mechanisms in rats (fructose diet and streptozotocin (STZ)-induced diabetes mellitus). MATERIALS AND METHODS Five groups with 10 rats per group were investigated: control group (healthy rats), fructose diet groups without any pre-treatme...

Residual stresses in fibre reinforced composites can give rise to a number of undesired effects such as loss of dimensional stability and premature fracture. Hence, there is significant merit in developing processing techniques to mitigate the development of residual stresses. However, tracking and quantifying the development of these fabrication-induced stresses in real-time using conventional...

BACKGROUND Filamentous Zygnematophyceae are typical components of algal mats in the polar hydro-terrestrial environment. Under field conditions, they form senescent vegetative cells, designated as pre-akinetes, which are tolerant to desiccation and osmotic stress. KEY FINDINGS Pre-akinete formation and desiccation tolerance was investigated experimentally under monitored laboratory conditions...

In practical engineering, coal burst is usually caused by the combination of high geo-stress and dynamic loading. To study response in conditions, numerical models a coupled static–dynamic split Hopkinson pressure bar (SHPB) test system were established, based on which impact tests for specimens at different speeds static pre-stress levels conducted. The mechanical properties, energy characteri...

background: the present study describes the susceptibility of prepubertal testis of mice to prooxidant induced oxidative impairments both under in vitro and in vivo exposure conditions. materials and methods: following in vitro exposure to iron (5,10 and 25 m), oxidative response measured in terms of lipid peroxidation and hydroperoxide levels in testis of pre pubertal mice (4 wk) was more robu...

Aim: To give easy remedy “Laughing” Skill to reduce the stress. Objectives: Old age is inevitable. But, it is possible to keep the mind agile and active to a great extent. The relation between age and stress is a close one. Aging may simply wear out the systems in the brain that respond to stress, so that they become inefficient. Methodology: A Quasi experimental study (non equivalent control g...

Developmental stress can significantly influence physiology and survival in many species. Mammalian studies suggest that pre- and post-natal stress can have different effects (i.e. hyper- or hypo-responsiveness) on the hypothalamic-pituitary-adrenal (HPA) axis, the main mediator of the stress response. In mammals, the physiological intimacy between mother and offspring constrains the possibilit...

this study was conducted to determine the effects of stomatal size and frequency on stomatal conductance, photosynthesis rate and yield, and to locate the genes controlling these traits. therefore, substitution lines series of ‘timstein’ (tim) into genetic background of ‘chinese spring’ (cs) were tested in a completely randomized block design with three replications under two normal and water s...
