Silent Risk Of Osteoporosis In Men With Prostate Cancer
Men being treated for prostate cancer using hormone therapy maybe under-recognized for their risk of developing osteoporosis, according to a new study. Researchers writing in the January 15, 2005 issue of CANCER, a peer-reviewed journal of the American Cancer Society, say few patients get tested for osteoporosis during treatment. Cancer-Killing Virus Shows Promise as Metastatic Cancer Treatment
The Seneca Valley Virus is a potent cancer killer and can differentiate between normal and cancerous cells. The virus may be a potential treatment for some metastatic cancers, such as small-cell lung cancer. Surprising New Role For Proteins In Sister Chromatid Cohesion
Scientists reveal a surprising new role for tDNAs and RNA polymerase III-associated proteins in sister chromatid cohesion. Sister chromatid cohesion (the binding together of the two identical copies of each chromosome that are formed during replication) helps to ensure that chromosomes are accurately segregated during the anaphase of the cell cycle. Sister chromatid cohesion is mediated by a multi-subunit protein complex called cohesin. Inside the cell nucleus, cohesin localizes to centromeres (the point of attachment of sister chromatids) as well as heterochromatin (condensed and genetically inactive regions of DNA). Obese Kidney Transplant Patients Twice As Likely To Die In The First Y
Six percent of obese kidney transplant patients die in the first year and 14 percent suffer transplant failures. The figures for non obese patients are three percent and eight percent. Experts from seven university hospitals in the Netherlands studied 2067 patients. Their finding appear in the November issue of Transplant International. The Academy Of Natural Sciences Probes What's Eating Historic USS Moni
The ironclad Civil War battleship USS Monitor rests in 240 feet of water off the North Carolina coast, but its ultimate fate may hinge on work done in a lab on the Benjamin Franklin Parkway. For nearly 140 years, the historic battleship lay at the bottom of the ocean, slowly deteriorating. Recovery efforts have brought to the surface hundreds of artifacts that conservators have set to preserving -- or so they thought. But a hidden enemy is mucking up the works. [Ironic] LONDON: A jailed cocaine dealer is working as Santa Claus on
John Tams, who dons beard, boots and red suit to work in a cafe's Christmas grotto, said he wanted to give something back to the community... Folate Mystery Finally Solved
Researchers have stumbled on the identity of an enzyme that had been a mystery for more than 30 years. They discovered the missing part of the pathway in how bacteria make the B vitamin folate. Tailoring Physical Therapy Can Restore More Functions After Neurologic
New research suggests a tailored approach to physical therapy after a neurological injury such as a stroke, traumatic brain injury or spinal cord injury could help restore a wider variety of functions. Scientists' 3-D view of genes-at-work is paradigm shift in genetics
New research has revealed for the first time that genes work together by huddling in clusters inside the nucleus -- the information center of a cell. These findings represent a paradigm shift in our understanding of how the genome is spatially organized in relation to gene expression. It marks the first step towards a 'virtual nucleus', a dynamic tool simulating interactions in the nucleus, which could revolutionize computer-based drug design. Life Cycle Of A Protein Observed With Single-Molecule Resolution
Using a sensitive, single-molecule measurement technique, researchers at the University of Illinois at Urbana-Champaign have observed the life cycle of RecA, a protein that plays a major role in repairing damaged DNA.
