Green synthesis, characterization, antioxidant, interaction with DNA/BSA, and investigation of cytotoxicity against MCF-7 cancer cells of zinc oxide nanoparticles using Hammada scoparia (Pomel) Iljin extract.

There is a need for advanced developments to battle aggressive breast cancer variations and to address treatment resistance. In cancer therapy, ZnO nanoparticles (NPs) possess the ability to selectively and effectively induce apoptosis in cancer cells. There is an urgent necessity to create novel anti-cancer therapies, and recent studies indicate that ZnO nanoparticles have significant promise.

[Accentuation of myocardial ischemia during coronary recanalization in the acute phase of myocardial infarction].

Coronary recanalisation during the acute phase of myocardial infarction, especially by in situ infusion of thrombolytic agents, is accompanied in most cases by rapid regression of chest pain and a reduction in the degree of ST elevation. However, a multicentre retrospective study of 104 attempts at recanalisation, including 78 successful procedures, showed in 10 cases (12.8 p.

[Myocardial infarction due to acute right coronary thrombosis. Treatment with in situ fibrinolysis, absence of angiographic residual stenosis].

The case of a 44 year old patient with inaugural postero-diaphragmatic myocardial infarction is reported. Coronary angiography performed at the 3 rd hour showed total occlusion of the right coronary artery at the level of its second segment. A streptokinase perfusion through a Judkins' catheter positioned in the ostium of the right coronary artery using Rentrop's technique, resulted in recanalisation of the vessel at the 45 th minute.
