When his serum creatinine rises to...
An aneurysm is a permanent ballooning in the wall of an artery. The pressure of blood passing through can force part of a weakened artery to bulge outward, forming a thin-skinned blister.

Description
Rizatriptan Benzoate is a selective 5-hydroxytryptamine (5-HT1) receptor agonist.
Mechanism of Action
Rizatriptan binds with high affinity to human cloned 5-HT1B and 5-HT1D receptors. Activation of these receptors results in cranial vessel constriction, inhibition of neuropeptide release and reduced transmission in trigeminal pain pathways.
Pharmacokinetics
Rizatriptan is completely...

It's surrounded by the lower edge of the stomach and the wall of the duodenum (the first portion of the small intestine leading out of the stomach). The pancreas has two major functions: to secrete fluid containing digestive enzymes into the duodenum and to secrete the hormones insulin and glucagon, which are needed to metabolise sugar,...

The first signs are likely to be barely noticeable - a feeling of weakness or stiffness in one limb, perhaps, or a fine trembling of one hand when it is at rest (activity causes the tremor to disappear). Eventually, the shaking will...

Roast beef, unpasteurized milk, apple cider, and...
It is often tempting to abandon old ways for glamorous new ones. Such is certainly the case for antibiotic development. However, a recent study by Andries and colleagues1 shows that established methods, enhanced by modern techniques, can be used to generate exciting results.
Traditionally, we have identified antibiotics by looking for compounds that block microbial growth. Since many pathogens...
Lice are tiny parasites that live on human beings and feed on blood. They seldom cause serious medical problems, but they are both annoying and contagious.
Every four hours or so, a louse bites into a tiny blood vessel for a meal. You don't feel the initial bites, because lice inject an anesthetic. However, the bites later begin to itch, and your scratching can lead to infection.
