pH comes from the term “power of Hydrogen”, or the hydrogen ion concentration present in a given solution. It helps to measure the acidity or alkalinity of a substance.

A single dose of doxorubicin-functionalized bow-tie dendrimer cures mice bearing C-26 colon carcinomas

In a dramatic demonstration of the power of nanotechnology, a team of investigators has designed a nanoscale, polymeric drug delivery vehicle that when loaded with a widely used anticancer agent cures colon cancer in mice with a single dose.

New wireless reflux disease technology more comfortable, not more effective

A wireless device that measures the acidity of stomach contents backwashed into the esophagus allows patients to avoid some of the nose pain and throat discomfort associated with the conventional wired monitor used to manage hard-to-treat gastroesophageal reflux disease.

Don't smoke and eat fish to keep your sight later in life

New research from Australia and the U.S. into Age-related Macular Degeneration, has found that cigarette smoking increases the risk but eating fish protects against it, and hormone replacement therapy makes no difference whatsoever.

Celiac success: New enzyme efficiently degrades gluten

A new enzyme originally developed for commercial food processing turns out to also quickly and nearly-completely break down whole gluten molecules as well as the T cell stimulatory peptides that cause celiac disease, a digestive disease with no current effective treatment other than avoiding wheat, barley or rye products.
