ackground: Knowing the human platelet antigens (HPA) and genes frequency in different populations is important not only for population studies but also for clinical transfusion practice. HPA genes frequency in Iran is not evaluated, so we investigated the HPA-2, HPA-3, and HPA-5 frequency and their polymorphism. Materials and Methods: DNA from 120 Iranians (99 Iranian blood donors and 21 patie...

North East of Iran sometime is influenced by heavy precipitation (HP) that causes plentiful damages. This paper aim to classifying and identifying the atmospheric circulation patterns related to heavy precipitation. This work increases my understanding from dynamic mechanisms that is generated by heavy precipitation. In this research, a heavy precipitation day has been considered if at least in...

Objective(s): Prenatal stresses increase incidence of neurodevelopmental disorders and influence cognitive abilities. Glucocorticoids are released in stress condition as endpoint activation of hypothalamus-pituitary-adrenal (HPA) axis. Evidence indicates a cross-talk between gut microbiota and brain function. This study assesses the effect of probiotic supplementation ...

Based on 40 years of daily precipitation, 272 extreme precipitation days in the Northern Xinjiang region are defined. Using data these days, four spatial patterns were obtained through principal component analysis. Then, daily-averaged reanalysis used to analyze variations synoptic systems and two before after. The rainfall centers shifted with influential at 500 hPa. Water vapor western Tiansh...

A tropical transition (TT) is the process whereby a baroclinic, high-to-moderate vertical wind shear, extratropical or subtropical cyclone transformed into warm-core, low cyclone. Thirty TT events were identified over central and eastern North Atlantic basin during period 1979–2019. The here studied from synoptic storm-centered composite climatology an environmental classification perspective. ...

The occurrence of major avalanche episodes in the Eastern Pyrenees (NE Spain) is estimated by means of the Poisson and the negative binomial distributions, assuming that they are rare events. The differences observed in their spatial distribution along the seven regions in which Eastern Pyrenees have been divided, suggests us to look for spatial variations in the relationship between extreme av...
