To Blood Platelets

شبیه‌سازی اثر تشعشات فضایی بر پلاکت‌های خون

The risk of leukemia and other radiation oriented diseases for astronauts increases with exposure to cosmic radiation. During the space missions, the blood and immune system change and the bones are affected by osteoporosis. In this research, a model, based on the human blood system, is presented for the study of the microgravity and the space radiation effects on the blood cells. This model is...

The source of HLA molecules on platelets: Does platelets adsorb soluble HLA molecules from their environment?

Background: The origin and function of human leukocyte antigen (HLA) class I molecules on platelets are still highly arguable. Given the differences in the results of the previous studies in this regard, the lack of research in recent years, and the clinical importance of HLA class I molecules, the absorption capacity of platelets for soluble HLA class I molecules was studied in this investigat...

Induction of apoptosis in human tumor cell lines by platelets

Introduction: It has been reported that platelets can eradicate tumor cells in vitro, although the mechanism of this effect has not been determined. The effect of platelets on the induction of apoptosis in tumor cells is largely unknown. Materials and methods: To investigate this effect, two human hematologic cell lines, K562 and Daudi, were independently faced with unstimulated and thromb...

Synergic effects of Summer Savory extract and aspirin on human platelets function

Introduction: Cardiovascular disease is one of the most common diseases in the world. In this account, atherosclerosis is one of the main cause’s heart attacks. Coagulation activity of platelets plays an important role in atherosclerotic plaque formation, thrombosis formation and cardiovascular diseases. Aspirin is the most commonly drugs which used as anti-platelet function to prevent and trea...

پیشرفت هایی جدید در زمینه شناخت پلاکتها

Platelets as cellular elements are the constituants of blood tissue and their main function is to participate in hemostatic processes. The glycocalyx which intimately surrounds the platelets contains a number of glycoproteins which are responsible for blood group specificity (ABO), tissue compatibility (human leukocyte antigen = HLA) , and platelet antigenicity. Platelets contain granules which...
