asthma is one of the fastest growing syndromes in many countries and is adding a huge cost to the health care system. increasing reports have linked airway infectious diseases to asthma. influenza is one of the most serious airway infectious diseases and in recent years there have been some serious influenza virus pandemics which caused increased fatality in numerous different populations. dive...
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...
conclusions the study results showed that stimulation of the american cockroach’s immunity system lead to production of antibacterial proteins and peptides which had inhibitory effect on the bacteria, depending on the bacterial strains and their sensitivity. likely this feature of insects can be used as therapeutic strategies to produce natural antimicrobial compounds against the pathogenic bac...
Abstract Introduction: Chronic heterogeneous stress may be better for evaluation of the effect of chronic stress situations on the nociceptive behaviour. The present study investigated the effects of chronic heterogeneous sequential stress on thermal-induced nociception and formalin induced pain behavior in rats. Methods: In the present study, adult rats (220-300 g) were used. Animals were ...
Two omega-3 fatty acids including docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are essential for the physiologic function of neuronal cell membrane. Normal function of neuronal cell membrane requires appropriate composition of fatty in its structure. Present study was designed to compare the effect of short-term and long-term pretreatment with omega-3 fatty acids on scopolamine...
Background: The pathophysiology of the varicocele has received considerable study, both in humans and in animal models. The sperm DNA damage and related oxidative stress have been identified as significant cause of male infertility. Present study was designed to evaluate the testicular nitric oxide (NO) generation, lipid and carbonyl groups (CGs) peroxidation and to analyze related sperm DNA da...
Introduction: Previous studies have indicated that stress levels of glucocorticoid hormones induce impairment of long term memory retrieval, but the underlying mechanisms (genomic or non-genomic) are not clear. To clarify this issue, we investigated the involvement of brain corticosteroid receptors and protein synthesis in the glucocorticoid-induced impairment of memory retrieval. Methods: 140 ...
The effect of different thiourea (TU) concentrations (10 and 20 mM) on antioxidants, protease activity and protein content with and without H2O2 (50 mM) induced stress was investigated in wheat leaves. A gradual decrease in protein content with a peak at 72 hours was observed in stressed as well as control leaves. This gradual decrease in leaf protein content at different time intervals was com...

Objective(s): Cholecystokinin (CCK) has been proposed as a mediator in stress. However, it is still not fully documented what are its effects. We aimed to evaluate the effects of systemic administration of CCK exactly before induction of stress on spatial memory and synaptic plasticity at CA1 in rats. Materials and Methods: Male Wistar rats were divided into 4 groups: the control, the control-C...
