Blood test may help signal tumor's remission, return in throat cancer patients

...hs, the researchers tested the patients’ blood for five proteins that, in previous studies, had been found to occur at heightened levels in head and neck cancer patients. These include two cytokines known as Interleukin (IL)-6 and IL-8, and three growth factors known as growth-related oncogene (GRO)-1, va...

Studies to find better ways to preserve human eggs, ovarian tissue under way

...ed a solution where we can warm up tissue in under five minutes and still get no ice formation,” says Dr. Song, adding that ice formation aside, it is difficult to thaw rock-solid tissue at room temperature in a matter of seconds, meaning the current approach could have extremely limited use. A study h...

In mice, drug protects against diabetes and atherosclerosis

A second group of animals ate the western diet for eight weeks, at which time they developed severe atherosclerosis. Then they were started on the drug to determine whether the drug could halt or revers...

By contrast, in Plasmodium, which causes malaria, about 20% of genes differ between related species. "Clearly there must have been considerable evolutionary p...

Clot-dissolving agent may be beneficial in treatment of severe frostbite

The preservation of limbs, which maximizes patient functional outcome, is perhaps the greatest benefit conferred by use of tPA in frostbite injury.” The researchers suspect tPA helps reduce the injury caused when frozen skin is war...
