The study on the ecophysiological impacts of stress in female Persian sturgeon broodfishes revealed that the average cortisol level varried in all broodfish caught at the Sefidrud River (163.38±21.2ng mL-1), Sefidrud River estuary (260.27±19.7ng mL-1) and Gorganrud River estuary (179.38±20.8ng mL-1). The variations in serum glucose levels were 140.65±12.05mg dL-1, 144.44±5.9mg dL-1 and 126.24±1...

The current research aims to examine the relationships between perceived stress, coping capability and general health of university students. The Perceived Stress Scale (PSS; Cohen et al., 1988), Coping Strategy Indicator (CSI; Amirkhan, 1990)and the General Health Questionnaire (GHQ; Goldberg, 1981) were administered to 1785 respondents from tertiary education institutions, aged 18 to 26 years...

The present study was conducted to assess the physiological and biochemical responses of winter vegetable radish (Raphanus sativus L.) to salinity stress. Salt stress markedly reduced biomass production of both radish varieties. Shoot fresh and dry weights were significantly reduced under salt stress, higher reduction was found at 120 mM NaCl as compared. Salt stress significantly reduced chlor...

There is an extensive and growing body of evidence that DNA replication stress is a major driver in the development and progression of many cancers, and that these cancers rely heavily on replication stress response pathways for their continued proliferation. This raises the possibility that the pathways that ordinarily protect cells from the accumulation of cancer-causing mutations may actuall...

Effects of different mother-infant separation procedures on experienced stress by adults and young were studied using changes in circulating eosinophil levels as a stress indicator. It was found that (1) the amount of stress experienced by the mothers increases with the age of the pups at separation, when separation occurs as 6-week-, 8-week-, and 10-week-old pups, (2) eosinophil levels of mink...

The aim of this study was to analyse the stress distribution in maxillary canines restored with different post systems and definitive crowns. The models of restored teeth with glass fiber, quartz fiber, titanium posts and crowns were developed with the Finite Element Method (FEM) in order to analyse their stress distribution when subjected to external compressive loads. Von Mises stress distrib...

a new medium, termed ecol was developed for the detection and enumeration of e. coli. the selective properties of ecol medium for the detection of e.coli from mixed culture in wastewater was tested and compared with conventional coliform media at 37°c and 44°c. results clearly showed that ecol medium was enable to direct confirmation of e.coli to be carried out by the indole reaction. the resul...

background: one of the main and basic pillars of health system promotion is the equitable distribution of health facilities in order to ensure fair access of people in the community to the health services. the goal of this study was to classify the health structural indicators in golestan province using scalogram analysis model. method: a descriptive study was conducted in 2010. data related to...

An electrogastrogram (EGG) recorded on the skin is believed to reflect the electrical activity of the gastrointestinal tract. In this study, linear correlations were calculated for the EGG spectral frequencies and the power ratios, changes in heart and respiratory rate before and during mirror drawing test (MDT) stress and after having meals, with the changes in the sympathetic tone indicator (...

Inducible NO synthase (iNOS) has been implicated in the pathogenesis of hypertension and target organ damage. We hypothesized that induction of iNOS contributes to left ventricular (LV) hypertrophy and dysfunction in mice with 2-kidney, 1-clip hypertension. Deletion of iNOS diminishes oxidative stress, thereby attenuating LV hypertrophy and enhancing cardiac performance. 2-Kidney, 1-clip hypert...
