Recently testing of Quantum-dot Cellular Automata (QCA) Circuits has attracted a lot of attention. In this paper, QCA is investigated for testable implementations of reversible logic. To amplify testability in Reversible QCA circuits, a test method regarding to Built In Self Test technique is developed for detecting all simulated defects. A new Reversible QCA MUX 2×1 desig...

The detection of viable myocardium or ischemically injured myocardium with a reversible impairment of contractile function remains clinically important but challenging. Detection of reversible dysfunction and distinction from irreversible tissue injury by positron emission tomography is based on identification of preserved or even enhanced glucose metabolism with F-18 2-fluoro 2-deoxyglucose. R...

BACKGROUND We hypothesized that among patients presenting with dyspnea on exertion (DOE), those who were found to have hyperdynamic left ventricle (i.e. LVEF ≥ 70%) on stress radionuclide myocardial perfusion imaging (RNMPI), are more likely to have features of diastolic dysfunction on transthoracic echocardiography. METHODS Medical records of 1892 consecutive patients who presented between F...

We report a case of reversible dilated cardiomyopathy, in a middle-aged male. The patient presented with severe left ventricular dysfunction and atrial fibrillation. Inspite of vigorous medical therapy there was only mild clinical improvement. Subsequently laboratory test results diagnosed it as hyperthyroidism and then specific thyrostatic treatment was added. There was a prompt clinical and h...

This prospective study evaluates the surgical outcome of 75 consecutive patients with impaired left ventricular function, including an analysis of predictors of the short-term outcome following coronary artery bypass grafting (CABG). Seventy-five patients (mean age 64 +/- 13 years) with coronary artery disease and impaired left ventricular function (left ventricular ejection fraction [EF] < or ...

BACKGROUND Cardiovascular disease is common cause of death in developed as well as developing countries. The most common cause of Ischemic Heart disease is narrowing of coronary arteries, a process called as atherosclerosis. The objective of the present study is to determine the pattern of ischemic changes detected by technetium tetrofosmin (Tc99m). METHODS Sixty five patients presenting as k...

A 61-year-old woman was admitted with general malaise, chest pain and breathlessness. During her inpatient stay she sustained a ventricular fibrillation (VF) arrest which was successfully terminated with direct current cardioversion. Cardiac investigations revealed poor left ventricular systolic function but unequivocally normal coronary arteries. During the course of her admission a macular ra...

Calcium plays a key role in heart muscle contraction and relaxation. Hypocalcemic heart failure is a rare and potentially reversible disturbance, which reflects this intrinsic relationship. The authors present the case of a 35-year-old woman who developed acute heart failure during the early postoperative period following total thyroidectomy. The echocardiogram showed severe global left ventric...

Background Neurological complications of diabetes and hyperglycemia are relatively common but the specific manifestations can vary widely. Diabetic striatal disease or "diabetic striatopathy" is an uncommon condition usually thought to result from hyperglycemic injury to the basal ganglia, producing a hyperkinetic movement disorder, usually choreiform in nature. Symptoms are generally reversibl...

This paper consists of two main results. The first one shows that if S is a left reversible semigroup of selfmaps on a complete metric space (M,d) such that there is a gauge function φ for which d(f(x),f (y)) ≤ φ(δ(Of (x,y))) for f ∈ S and x,y in M , where δ(Of (x,y)) denotes the diameter of the orbit of x,y under f , then S has a unique common fixed point ξ in M and, moreover, for any f in S a...
