Prenatal stress can cause long-term effects on cognitive functions in offspring. Hippocampal synaptic plasticity, believed to be the mechanism underlying certain types of learning and memory, and known to be sensitive to behavioral stress, can be changed by prenatal stress. Whether enriched environment treatment (EE) in early postnatal periods can cause a recovery from these deficits is unknown...

The lack of specificity pesticides used for control various organisms, even if efforts have been made to design formulations more species-specific, produce harmful effects on non-target organisms. Oxidative stress and lipid peroxidation are amongst the main known induced by pesticide exposure, besides eventual lethal toxicity, endangering organisms’ biomembranes integrity or compromising their ...

The periodontal ligament (PDL) contains oxytalan fibers as well as collagen fibers, which helps it to withstand the mechanical stress to which it is constantly exposed. The oxytalan fibers are produced by PDL fibroblasts. However, the arrangement of PDL fibroblasts and the orientation of oxytalan fibers relative to the fibroblast cell axis have not been investigated under the condition of mecha...

background: non-ulcer dyspepsia (nud) is one of the common gastrointestinal disorders considered as a psychosomatic disorder. the effectiveness of psychological intervention in improving symptoms of this disease remains unclear. the objective of this study was to assess the effects of add-on stress management training on symptoms of nud. materials andmethods: in a randomized clinical trial, 28 ...

following the recent work of the authors in development and numerical verification of a new kinematic approach of the limit analysis for surface footings on non-associative materials, a practical procedure is proposed to utilize the theory. it is known that both the peak friction angle and dilation angle depend on the sand density as well as the stress level, which was not the concern of the fo...

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...
