Chemotherapy Pill Has Fewer Side Effects Than IV

...the body, capecitabine is designed to target tumor cells directly. Patients taking the oral drug were significantly more likely to respond to treatment than those on standard chemotherapy, and side effects, including diarrhoea, hair loss, nausea and gastrointestinal tract ulcers, were less common in patie...

Leptin linked to Blood Clots

...can Medical Association. Leptin is released by fat cells and signals the body to stop eating. But this system can break down in overweight people, Eitzman explained. Leptin levels can get too high among obese individuals and when that happens, the person can become resistant to leptin's signals, making the...

Transforming stem cells to lung cells

The functioning of stem cells has an outstanding nature. Initially, the mouse stem cells have been transformed into fully-functioning lung cells, promising repair of damaged lung tissue. Th...

In clinical studies, the drug eased symptoms and cut the duration of colds by about a day. One concern is that pleconaril tablets must be taken within 24 h...

Gene therapy - Aim to improve blood flow

... Francisco, found a way to produce mice whose skin cells had high levels of activity of a gene called HIF-1. Researchers have managed to produce a genetically-altered mouse which has grown large numbers of new blood capillaries in its skin. This gene is known to send commands to several other genes, incl...
