Physician researchers with only an M.D. degree are less likely to receive NIH research grants than researchers with a Ph.D. degree or those with both M.D. and Ph.D. degrees, according to a study in the June 13 issue of JAMA.
At the heart of most, if not all cancers, lie a handful of wayward stem cells that feed the ever growing tumor mass, but their scarcity make it difficult for scientists to study them. Now, times of plenty may lie ahead as a breast cancer cell line — established long ago — turned out to behave a lot like cancer stem cells.
A Swiss-based research team has published a new mechanistic description of how tumor cells migrate to the lymphatic system in the early stages of tumor metastasis. This new understanding holds significant potential for developing anti-metastasis therapies.
Stem cell biology takes another exciting leap forward as scientists report that normal tissue cells can be reprogrammed to exhibit many of the properties that are characteristic of embryonic stem cells, including the ability to give rise to multiple cell types and contribute to the germline.
Blocking a single protein with an experimental drug prevented and treated both type 2 diabetes and atherosclerosis in laboratory mice that had been fed unhealthy diets and were genetically predisposed to these common killers, according to an article published online at Nature on June 6, 2007.
The notion that East Asians, Japanese in particular, are self-effacing and have low self-esteem compared to Americans may well describe the surface view of East Asian personality, but misses the picture revealed by recently developed measures of self-esteem, according to a new study by a team of researchers from the United States, China and Japan.
Andrew Speaker learned Monday evening that his third consecutive sputum smear test had come back negative. This confirmed results from several smear tests previously performed at other institutions.
A close cousin of the bacterium that debilitated thousands of World War I soldiers has been isolated at UCSF from a patient who had been on an international vacation. The woman, who has since recovered, suffered from symptoms similar to malaria or typhoid fever, two infections that can occur in returning travelers.
The U.S. Food and Drug Administration (FDA) today issued final recommendations to increase the supply of safe and effective influenza vaccines for both seasonal and pandemic use.
In a retrospective study of 700 patients with culture-positive tuberculosis (TB), relapse rates were found to be significantly higher in HIV-infected patients compared to HIV-uninfected patients following a rifamycin-based regimen.
