this study aimed at determining the chronic and acute effect of submaximal pedaling activity along with blood flow restriction on serum bdnf, tnf-α and bdnf/tnf-α ratio in active men. 24 physical education students at kharazmi university volunteered for the study. they were divided into three groups: pedaling with lower extremity vascular occlusion (n=8), pedaling without occlusion (n=8), and c...

recently multiple studies have shown that elevated homocysteine levels may be associated with ophthalmic vascular disease. to investigate the role of high plasma levels of homocysteine in the patients with retinal vein occlusion, 21 patients with retinal vein occlusion (rvo) and 20 age and sex matched controls without rvo were included in this retrospective case–control study. information regar...

La patología vascular oclusiva es causante de diversas y variadas manifestaciones clínicas, algunas ellas con catastróficas consecuencias para el paciente. Dado que las causas tal oclusión son muy variadas, hemos abordado en un artículo previo reciente esta misma revista trombóticas. En presente recopilamos adicionales intravascular. Vascular occlusion has multiple, diverse clinical manifestati...

There is evidence that aspirin is partially effective in the prophylaxis of various vasoocclusive disorders. This article reviews pharmacologic opportunities for improvement over and above the therapeutic effect of aspirin. It is concluded that several rational possibilities merit consideration, in particular, the use of combinations of drugs that affect the thrombotic process at different poin...

Coronary angiography has proved beyond doubt that complete coronary occlusion is the rule in the very early hours of infarction. The 60% to 80% rate of coronary recanalization after thrombolytic therapy has proved that thrombosis is a major component of the occlusion at the time when the procedure is performed a few hours after the onset of symptoms. However, the trigger for coronary thrombosis...

Selective inhibitors of thromboxane synthase have two theoretical advantages over inhibitors of the cyclooxygenase enzyme as potential antithrombotic compounds. First, they do not prevent formation of prostacyclin, a platelet-inhibitory, vasodilator compound, coincident with inhibiting thromboxane biosynthesis. Second, the prostaglandin endoperoxide substrate that accumulates in the platelet in...

Background. Hazards of liver surgery have been attenuated by the evolution in methods of hepatic vascular control and the anesthetic management. In this paper, the anesthetic considerations during hepatic vascular occlusion techniques were reviewed. Methods. A Medline literature search using the terms "anesthetic," "anesthesia," "liver," "hepatectomy," "inflow," "outflow occlusion," "Pringle," ...

Puroose: Proliferative diabetic retinopathy is assumed to develop because vasogenic factors are released from retinal areas that are ischaemic and hypoxic secondary to occlusion of the retinal vascular bed. It has been propclsed that vascular occlusion in diabetic retinopethy may be due to the deposition of periodic acid Schiff positive glycoprotein compounds in the retinal vascular walls. but ...
