Thrombosis is the major mechanism underlying acute complications of atherosclerosis. Although thrombogenicity of atherosclerotic plaques has been ascribed to activation of the extrinsic pathway of blood coagulation, in the present study we investigated contribution of the intrinsic factor VIII (fVIII)-dependent pathway. We found that in vitro exposure of human macrophages and smooth muscle cell...

background: the anti-cancer effects of honey bee venom (bv) and chrysin might open a new window for treatment of chemo-resistant cancers. this study was designed to evaluate cytotoxic and pro-apoptotic effects of bv and chrysin on a2780cp cistplatin- resistant human ovarian cancer cells. methods: as per the study objectives, a2780cp cells were categorized to 4 groups: 3 experiment groups (treat...

INTRODUCTION The blood coagulation cascade consists of two pathways, the tissue factor (TF)-dependent extrinsic pathway and the contact factor-dependent intrinsic pathway. We have previously shown that a direct thrombin inhibitor, melagatran, paradoxically increased TF-induced thrombin generation (TG) in thrombomodulin (TM)-containing human plasma in vitro. However, the effect of melagatran on ...

Apoptosis or programmed cell death is a gene regulated phenomenon which is important in both physiological and pathological conditions. It is characterized by distinct morphological features including chromatin condensation, cell and nuclear shrinkage, membrane blebbing and oligonucleosomal DNA fragmentation. Although, two major apoptotic pathways including 1) the death receptor (extrinsic) and...
