One of the rare but most challenging issues in the management of the locally-advanced breast cancer (LABC) is life-threatening bleeding from the fungating and/or ulcerating focus (foci) of these tumors. Breast surgeons may need the assistance of interventional radiologists to solve this urgent condition if surgery cannot provide sufficient benefit. Herein, we report a case of recurrent locally-advanced breast cancer that presented with sudden severe bleeding, which was stopped by an interventional ...

The chronic consumption of androgenic anabolic steroids has shown to cause atrial arrhythmias. Several studies have suggested that the interval from the peak to the end of the electrocardiographic T wave (Tp-e) may correspond to the transmural dispersion of repolarization and that increased Tp-e interval and Tp-e/QT ratio are associated with malignant ventricular arrhythmias. The aim of this study was to evaluate repolarization dispersion measured from the 12-lead surface electrocardiogram (including ...

Abstract: The pathophysiologic mechanisms leading to acute ischemic renal failure are not completely understood. Melatonin, a compound with well‐known antioxidant properties, reduces IR‐induced renal injury. The purpose of the present study was to investigate the changes in levels of tumor necrosis factor (TNF)‐ α , IL‐ β , and IL‐6 in postischemic reperfused renal tissue, and to determine whether the protective effect of melatonin is related the modulation of the production of these inflammatory molecules. ...

AbstractExtremely low frequency (ELF) electromagnetic field (EMF) is thought to prolong the life of free radicals and can act as a promoter or co-promoter of cancer. 8-hydroxy-2′-deoxyguanosine (8OHdG) is one of the predominant forms of radical-induced lesions to DNA and is a potential tool to asses the cancer risk. We examined the effects of extremely low frequency electro magnetic field (ELF-EMF) (50 Hz, 0.97 mT) on 8OHdG levels in DNA and thiobarbituric acid reactive substances (TBARS) in plasma. To ...
