Reducing Knee Pain And Reliance On PainkillersOlder people with knee pain who receive their main care from physiotherapists and pharmacists are more likely to experience improvements in pain levels and knee function, and are less likely to need NSAIDs (non-steroidal anti-inflammatory drugs, eg asprin and ibuprofen), as per a BMJ study.

In Early Embryos, Cilia Get The MessageHaving your heart in the right place commonly means having it located on the left side of your body. But just how a perfectly symmetrical embryo settles on what's right and what's left has fascinated developmental biologists for a long time.

Newspaper Articles Skew Coverage Of ComasNewspaper articles skew coverage of comas by focusing heavily on patients who are more likely to awaken and recover, thus possibly leading the public to think that coma patients have better odds than they truly do.

Cancer Stem Cells Linked To Radiation ResistanceCertain types of brain cancer cells, called cancer stem cells, help brain tumors to buffer themselves against radiation therapy by activating a "repair switch" that enables them to continue to grow unchecked, scientists at Duke University Medical Center have found.
The scientists also identified a method that appears to block the cells' ability to activate the repair switch following radiation therapy. This finding may lead to the........Go to the Cancer-blog (Added on 10/18/2006 10:38:35 PM)
