animal studies

In animal studies, scientists discover different inflammatory pathways at work. Relatively new drugs now help some patients, but not others, with the most common form of multiple sclerosis.

That may be because patients with the same symptoms experience different types of inflammation, suggests a new study in animals.

If the differences are found in people, future treatments may be tailored to specific subtypes of the disease.

After a stroke, even unaffected areas of the brain are at risk -- depolarization waves arise at the edges of the dead tissue and spread through the adjacent areas of the brain.

If these waves are repeated, more cells die. This has previously been observed only in animal studies.

A family of compounds derived from black pepper extract have shown potential in animal studies to be effective in treating vitiligo, a skin pigmentation disorder.

Vitiligo, which afflicts an estimated 100 million people worldwide, is characterized by the loss of pigment in affected areas of skin.

A unique study proposes a new paradigm in cancer treatment: instead of selectively attacking cancer cells, protect all the healthy cells.

Animal studies and in vitro human cell studies show that a short fast protects healthy cells against chemotherapy, while tumor cells remain sensitive to the drugs.
