The impact of radiation-induced bystander effect (RIBE) is still not well understood in radiotherapy. RIBEs are biological effects expressed by nonirradiated cells near or far from the irradiated cells. Most radiological studies on cancer have been based biochemical characterization. However, biophysical investigation with label-free techniques to analyze and compare direct irradiation RIBE has...

نقش سلولهای خونی به عنوان اجزای اصلی دفاع فیزیولوژیک حشرات مهم گزارش شده است. اولین فاکتورهای سیستم گردش خون هستند که در مقابله با انواع تنشها و عوامل بیگانه مشارکت می کنند. تحقیق حاضر، چهار نوع هموسیت همولنف لارو سن چهارم خرطوم بلند دمبرگ چغندرقند شناسایی شد شامل پروهموسیتها، گرانولوسیتها، پلاسموتوسیتها انوسیتوئیدها هستند. بزرگترین از نظر اندازه بودند مجموع فراوانی گرانولوسیتها لاروهای سنین سو...

objective: cancer is a major health problem worldwide and current therapies for cancer are often limited by short-term efficacy due to drug resistance. there has been much interest in the use of naturally occurring compounds with chemo-preventive and chemotherapeutic properties in the treatment of cancers. rose is one of the most important groups of ornamental plants which their fruits and flow...

Glucosaminyl(acyl)phosphatidylinositol [GlcN(acyl)PI], the third intermediate in the mammalian glycosylphosphatidylinositol (GPI) anchor pathway, is undetectable in most cells. This intermediate was previously shown to accumulate, however, in murine lymphoma mutant E and in yeast mutant dpm1, both of which lack dolicholphosphomannose synthase activity. Here we report that a mammalian HeLa S3 su...

toxoplasmosis is a protozoal infection caused by toxoplasma gondii. toxoplasmosis produce severe damage in patients who are immunosuppresed. in those who are immunosupressed, latent infection can be reactivated resulting in acute disseminating disease. betamethasone is a synthetic glycocorticoid, used as an anti-inflamatory and immunosuppressant in a wide variety of disorders.the aim of this st...

Background: Cervical cancer is the second most common female cancer worldwide. Inhibitors of apoptosis proteins (IAPs) block apoptosis; therefore, therapeutic strategies targeting IAPs have attracted the interest of researchers in recent years. Apollon, a member of IAPs, inhibits apoptosis and cell death. RNA interference is a pathway in which small interfering RNA (siRNA) or shRNA (short hairp...
