A patient with acute severe mitral regurgitation resulting from papillary muscle dysfunction which developed on the third day of acute myocardial infarction underwent early successful mitral valve prosthetic replacement with concomitant aortocoronary saphenous vein bypass. The concept of acute severe mitral regurgitation due to an infarcted papillary muscle which has not actually ruptured and a...

Jamming phenomena are observed everywhere in our daily live. These stagnations in flow occur not only on highways, but also in stadiums, in public transportation like buses and trains, in the world of the Internet, and even in our bodies.

At the same time, I am almost overwhelmed with humility and gratitude to those who helped me achieve our goals during the last 27 years. This is without a doubt the high point of my career ...

A review of the congenital anomaly of coarctation of the aorta has been presented. The salient features in diagnosis are the differential pressures and pulses between the upper and lower extremities. Also, the features of left ventricular hypertrophy and pulsating intercostal vessels are significant. The essential complications are those of sustained hypertension. In most cases surgical correct...

Oil price forecasting has received a great deal of attention from practitioners and researchers alike, but it remains difficult topic because its dependency on variety factors, including the economic cycle, international relations, geopolitics.

An autocatalytic reaction in which the reaction product serves as a catalyst to produce more of itself and to suppress production of its enantiomer serves as a mechanistic model for the evolution of homochirality. The Soai reaction provided experimental confirmation of this concept, nearly 50 years after it was first proposed. This Perspective offers a rationalization of the Soai autocatalytic ...

Blue Green Algae (BGA) have the capacity to self generate photosynthates from CO and 2 water. It is gratifying to note that Aulosira is the most important alga of the rice fields of India. Algalization has been found to benefit all the growth parameters. The propagation of BGA enriches the N status of soil and also provides organic matter and biological quotient 2 substances for plant growth. T...
