Stanford researchers find culprit in aging muscles that heal poorly

...s. It was while the researchers were testing the opposite situation - how the repair capabilities of young muscle stem cells were affected by being placed in an aged environment - that the Wnt pathway came to light. The work was done with live mice whose circulatory systems were joined, and in lab dishes wi...

New research discovers independent brain networks control human walking

...ich varying speeds were applied to legs walking in opposite directions, was found to interfere with subsequent normal forward and backward walking. The combined results demonstrate there are distinct brain modules responsible for right/forward, right/backward, left/forward and left/backward walking. Most sign...

Electric fields have potential as a cancer treatment

...le moment, in which there is a large separation of opposite electric charges. Therefore, parts of the mitotic spindle are greatly influenced, and apparently disrupted, by an electric field. The second effect of the 200 kHz fields is that they sometimes disintegrated the daughter cells just before they split...

Further analysis led the researchers to determine that the new imaging techniques provided an increase in contrast between 150 to 200 percent to discriminate between breast cancer and benign ti...

Chemotherapy may enhance the effectiveness of brain tumor vaccines

...as M. D. Anderson Cancer Center has found that the opposite is true: chemotherapy may actually enhance the effectiveness of the vaccines.
