background and aims: 25-hydroxy vitamin d3 is recognized to be an essential element for healthy body; however, its deficiency has been identified as a risk factor for thyroid disease, diabetes mellitus and other autoimmune diseases and infectious diseases. thyroid disease is common in the general population that its prevalence increases proportional to age. subjects with poorly controlled diabe...

Legume-Rhizobium nitrogen fixation is dramatically affected under drought and other environmental constraints. However, it has yet to be established as to whether such regulation of nitrogen fixation is only exerted at the whole-plant level (e.g. by a systemic nitrogen feedback mechanism) or can also occur at a local nodule level. To address this question, nodulated pea (Pisum sativum) plants w...

It is over two decades that groundwater flow models are routinely implemented for better management of groundwater resources.Modeling groundwater flow with the help of the ground water modeling system (GMS) in the Damghan plain aquifer in northern Iran,which experiences declining levels and numerous environmental hazards, has demonstrated that, (a) in the worst case scenario theaquifer will fac...

The number of breakthrough pathogenic activity in water distribution network system is constantly increasing day by day especially at level of consumption. Bacterial growth or survival rate often relates to acidity and alkalinity of water. Sudden changes in pH value and temperature indicates a possibility of present bacterial contaminant in aqueous environment. The observation of pH- and temper...

Many complicated mechanisms are involved in brain ischemia and the role of inflammatory factors in the progression of post-ischemic injury is inevitable. In present study, anti-inflammatory effect of berberine has been investigated in reperfusion injury after acute ischemic stroke. Male Wistar rats weighing 250-270 gr were randomly divided into four cohorts: healthy rats (control, n=20), sham-o...

Purpose: The aim of this study was to investigate the role of cognitive emotion regulation in predicting high-risk behaviors mediated by the well-being of 14-17 year old girls in Saravan. Methodology: This research was descriptive and correlational by structural equation modeling method based on partial least squares approach. The statistical population included all 14 to 17 year old male stud...
