several methods are available to produce haploid plants. one of the most efficient methods is especially microspore culture. stress as a triggering factor is essential for embryogenesis induction in microspores. in the first experiment, the effect of different thermal stresses including cold treatments and heat stress and the control were evaluated. in the second experiment, the effect of 2,4-d...

Objective(s):A growing interest has recently been attracted towards the identification of plant-based medications including those with protective effects against cognitive impairment. Sesamol has shown promising antioxidant and neuroprotective effects, therefore, we aimed to evaluate its therapeutic potential in epilepsy which is commonly associated with oxidative stress and cognitive impairmen...

background: recently, it has been revealed that tyrosine kinase inhibitors (tkis) act through inducing both oxidative and endoplasmic reticulum (er) stress in chronic myeloid leukemia cells. however, er stress signaling triggers both apoptotic and survival processes within cells. nevertheless, mechanisms by which tkis avoid the pro-survival effects are not clear. the aim of this study was to ev...

Objective(s): Long-term exposure to stress leads to memory deficits and certain mood disorders such as depression and anxiety. We aimed to study the effect of gallic acid (GA) on chronic restraint stress (CRS) induced anxiety and memory deficits in male BALB/c mice.Materials and Methods: Ninety male BALB/c mice were assigned to nine groups including caged control (CC): food-water deprived (FWD)...

Silicon is known to ameliorate the deleterious effects of drought on plant growth. We evaluated growth of wheat (Triticum aestivum L. CV. Chamran) under Water-Deficit Stress Induced by Polyethylene Glycol as affected by Si application. In this article, the effects of Si (as potassium silicate) on some parameters related to growth, chlorophyll concentration relative water content (RWC), electrol...

Introduction: Stress is associated with neurological and cognitive disorders. It has been suggested that doxepin, in addition to its influence on the content of neurotransmitters, has probable neuroprotective effects as well. Therefore, the aim of this study was to investigate the effects of doxepin on synaptic plasticity and brain-derived neurotrophic factor (BDNF) gene expression in the rat h...

the present paper is devoted to a new critical state based plasticity model able to predict drained and undrained behaviour of granular material. it incorporates a bounding surface plasticity model describing in multilaminate framework to capitalize on advantages of this mathematical framework. most of the models developed using stress/strain invariants are not capable of identifying the parame...

background and objective: a huge amount of investigational evidence support a role for oxidative stress as an intermediary of nerve cell dysfunction in parkinson’s disease (pd). polyphenols such as carvacrol have been indicated to prevent neuronal deterioration caused by increased oxidative load, thus, this study evaluated whether carvacrol administration would attenuate behavioral abnormalitie...

oxidative stress is one of the important causes of the type 1 diabetes induced changes in the sperm quality. bioflavonoids, rutin 10 mg/kg and naringin 10 mg/kg were evaluated for their protective effects on sperm parameters, oxidative stress, and histopathology of type 1 diabetic rats. results demonstrated the reduction in sperm count, sperm motility and vitality in diabetic rats. mass drug ad...

introduction : tardive dyskinesia is one of the major side effects of long-term neuroleptic treatment. increased reactive oxygen species and oxidative stress has been proposed as possible etiopathologic mechanisms. ginkgo biloba extract (egb) is a natural antioxidant. we investigated the effects of ginkgo biloba extract on neuroleptic-induced orofacial dyskinesia in rats, a potential animal mod...
