Background: Thrombocytopenia occurs in 1-5 % of newborns (platelet count < 150 × 109/L). Low platelet 50 109/L leads to the hemorrhagic syndrome, with one its causes being neonatal alloimmune thrombocytopenia resulting from incompatibility between mother and fetus human antigens (HPA) inherited father absent mother, which formation maternal antibodies. Anti-HPA-1a, anti-HPA-5b, anti-HPA-3a, ...
Introduction: increasing dusty storms has been one of the most important consequences of climate change in recent years that directly or indirectly affected human society. Countries located in the arid and semiarid regions of the world, including Iran, have been affected more than other parts of the globe by this natural disaster and its harmful consequences, especially the atmospheric dust, wh...
Abstract Background and Objectives Immune platelet refractoriness is a complication of blood transfusion in patients with multiple platelet transfusions. Antibodies against surface antigens, including human platelet antigens (HPAs) and human leukocyte antigens (HLAs), can be produced which can cause the degradation of transfused platelets by macrophages. In this study, the frequency of platele...
in this thesis, we consider a mathematical model of cancer with completely unknown parameters. we study the stability of critical points which are biologically admissible. then we consider a control on the system and introduce situations at which solutions are attracted to critical points and so the cancer disease has auto healing. the lyapunov stability method is used for estimating the un...
Abstract The influence of Rossby waves emitted in the northeastern Pacific Ocean on Northern Hemisphere’s atmosphere during summer is analysed using ERA5 reanalysis and a new large ensemble performed with EC-Earth3 model. Wave Sources (RWS) trigger wave-like patterns arising from upper troposphere north-eastern region, causing response around Hemisphere alternating regions positive negative cor...
The effective patterns and mechanisms of synoptic systems during the wet and dry spells in Midwest of Iran(MWI) analyzed and discussed on seasonal scales from 1974 to 2003. Synoptic Analysis is based on synoptic chartson Sea Level Pressure (SLP), 850 and 500 Hpa levels. The results of synoptic analysis show that dry spells in MWIare mostly corresponded to Azores High (AZH) intensifying and its ...
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...
