Minimally Invasive Cancer Treatments Highlighted

..., November 28) Although surgery provides the best chance for a cure, liver tumors are often inoperable because they may be too large, or have grown into major blood vessels or other vital structures. Sometimes, many small tumors are spread throughout the liver, making surgery too risky or impractical. Surg...

Scientists would like to develop drugs that use photolyase's mechanism to repair UV damage in human skin, but they've had trouble with the first steps ?replicating the photolyase reaction in the labo...

Old drug shows new promise for Huntington's Disease

...echanism of the drug, he explained, the better the chance that researchers might eventually be able to create a medication that is both safe and effective.
