Do we really know why cardiac surgery is still affected by substantial inflammatory reaction?

Modern cardiac surgery was born in early fifty’s with the use of the heart lung machine. This machine allowed to bypass the heart and the lung, draining the blood from the right atrium, oxygenating and pumping it

How alkaliphiles produce energy to sustain their life under extremely low concentration of proton

Alkaliphiles are defined as microorganisms with optimum growth pH of above 9 (10-9 mol dm−3 H+ concentration).  This means that these microorganisms can grow in environment with one-hundredth times lower proton (H+) concentration than that of neutral

Recent trends in treating kidney stones

Kidney stones are incredibly common in the United States and the prevalence is increasing at a remarkable rate.  In the United States, the chance of a man having a kidney stone at some point in his life

MOF for oxoanion pollutant sequestration

The cosmetic and functional results of creating a vagina by use of penile and scrotal skin in male-to-female transsexuals are, in general, satisfactory. One of the goals of creating a vagina is to create tactile and erogenous

Atom tunneling in chemistry

While macroscopic objects from everyday life follow the classical laws of physics, microscopic objects obey the laws of quantum mechanics. These quantum objects, such as light (photons), electrons, and atoms, show characteristics of particles as well as

Statins and diabetes: do the benefits outweigh the risks?

Cardiovascular disease (heart attack and stroke) is the leading cause of death in the United States. Prescription cholesterol-lowering medications have been shown to lower the risks for heart attacks and stroke. In fact, roughly 28% of Americans
