objective: in order to study the effect of drought stress, salicylic acid (sa) and jasmonic acid (ja) foliar application on hill reaction and photosynthetic pigments. methods:experiment was done as factorial on the basis of completely randomized design in 4 replications. irrigation in 3 levels (fc, fc and fc), salicylic acid in 2 levels (0 and 0.5 mm) and jasmonic acid in 2 levels (0 and 50...
Background & Objectives: Many studies were conducted to determine the effects of heat stress on human performance. However, they could not reach a decisive conclusion, mainly due to a large variation in experimental conditions and tests. This study investigated cognitive performance of university students exposed to different levels of heat stress under laboratory condition. Methods: I...
Background and purpose: Multiple sclerosis (MS) is a chronic disease of the central nervous system which is accompanied by cognitive dysfunction. The aim of this study is to compare the sustained attention and reaction time in patients with MS and healthy normal individuals considering their level of depression, anxiety, and stress. Material and methods: This causal-comparative study recruited...
we describe here a suitable approach for the synthesis of n-unsubstituted monocyclic b-lactams under mild reaction conditions by the annelation of imines with substituted acetylchlorides. in this method the reaily available phtalimidoacetyl chloride were allowed to react with - dibenzylideneiminotoluene (hydrobenzamide) in the presence of an equimolar amount of triethylamine in refluxing toluen...
Cancer treatment is still of the greatest challenges that health care providers and patients are facing. One of the unsolved problems in cancer treatment is cells’ reaction to metabolic stress caused by harsh nutritional conditions around tumor. In order to be able to treat this disease properly, it is important to understand the true nature of the disease. In fact, the cells inside the central...

BACKGROUND Acute stress reaction is a diagnosis given immediately following the experience of an exceptional mental or physical stressor. To the best of our knowledge, no study has examined the association between acute stress reaction diagnosis and suicide. The current study examined this association in a population-based sample. In addition, we examined comorbid psychiatric diagnoses as modif...
Introduction: Heat stress is one of the Hazardous physical agents in the workplace, which can cause impairment of cognitive performance. The current study aimed to evaluate the effect of different levels of heat stress on attention and reaction time in a laboratory condition. Material and Method: This experimental study was done among 33 students included 17 males and 16 females. Mean age of...
