The current trends in high performance integrated circuits are towards faster and more powerful circuits in the giga-hertz range and even further. As the more complex Integrated Circuits (IC) such as microprocessors have been entering the giga-hertz operating frequency range, various speed related roadblocks have become increasingly difficult to overcome.(More)
External sources, either within or outside the hospital environment, may interfere with the appropriate function of pacemakers which are being implanted all around the world in current medical practice. The patient and the physician who is responsible for follow-up of the pacing systems may be confronted with some specific problems regarding the various(More)
Removal of free oxygen radicals, generated during reperfusion of an ischemic organ by scavengers protects the tissue from reperfusion injury. The calcium channel blocker verapamil is an effective cytoprotective agent, preventing against reperfusion injury. The effects of verapamil were investigated previously using hepatic, renal or cardiac(More)
OBJECTIVES Amifostine is a drug which can eliminate free oxygen radicals that appear in the body after radiation or chemotherapeutic agent exposure. It is used to decrease the renal toxicity of cisplatin. The aim of this study was to determine the role of amifostine in warm ischemia kidney model for prevention of ischemia/reperfusion injury and also to find(More)
A previously healthy 31-year-old man with a history of smoking presented with severe prolonged chest pain for more than one hour duration. ECG taken on admission revealed slightly widened QRS complexes, and ST segment elevations in leads aVR, aVL, V 1 and V 2 in contrast to up-sloping ST-segment depressions in leads D II , D III , aVF and V 3–6 at the J(More)
BACKGROUND Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are inflammatory markers used as prognostic factors in various diseases. The aims of this study were to compare the PLR and the NLR of heart failure (HF) patients with those of age-sex matched controls, to evaluate the predictive value of those markers in detecting HF,(More)
