These cells, known as circulating tumor cells, or CTCs, can provide critical information for examining and diagnosing cancer metastasis, determining patient prognosis, and monitoring the effectiveness...
Life Sciences |With thousands of stinging cells that can emit deadly venom from tentacles that can reach ten feet in length, the 50 or so species of box jellyfish have long been of interest to scientists and to the ...
Life Sciences |The largest national stem cell study for heart disease showed the first evidence that transplanting a potent form of adult stem cells into the heart muscle of subjects with severe angina results in le...
Life Sciences |The TiO2 nanoparticles induced single- and double-strand DNA breaks and also caused chromosomal damage as well as inflammation, all of which increase the risk for cancer. The UCLA study is the first t...
Life Sciences |In a study available online and appearing in a future issue of Proceedings of the National Academy of Sciences, a UT Southwestern Medical Center researcher and his collaborators in California show tha...
Studies and Analyses |Dr. Michael Stilmann, Dr. Michael Hinz and Professor Claus Scheidereit have shown that the protein PARP-1, which detects DNA damage within seconds, activates the transcription factor NF-kappaB, a well...
Life Sciences |While they are powerful killers of some breast cancer cells, new drugs called histone deacetylase inhibitors, or HDAC inhibitors, also increase self-digestion, or autophagy, in surviving, mega-stresse...
Health and Medicine |Hardening of the arteries has been detected in Egyptian mummies, some as old as 3,500 years, suggesting that the factors causing heart attack and stroke are not only modern ones; they afflicted ancie...
Health and Medicine |Whether rallying the crowd at a sporting event or participating in competition, cheerleading can be both fun and physically demanding. Although integral to cheerleading routines, performing stunts can...

Health and Medicine |Heart experts at Johns Hopkins are calling premature the early halt of a study by researchers at Walter Reed Army Medical Center and Washington Hospital Center on the benefits of combining extended-re...
Health and Medicine |How do strokes occur? What tends to happen is that a clot blocks the blood vessels supplying the brain. The brain then becomes starved of blood and oxygen, as a consequence of which nerve cells start ...
Life Sciences |The work provides the first evidence that a lipid can initiate the suicidal, or apoptotic, response in cells. The findings involve a lipid called GM1-ganglioside. Lipids are fat-like molecules. GM1 bu...
