Stem Cell :: 3-D scaffold for growing stem cells
Stem cells grew, multiplied and differentiated into brain cells on a new three-dimensional scaffold of tiny protein fragments designed to be more like a living body than any other cell culture system.

Colorectal Cancer :: Early colon cancer diagnosis with colonoscopies made possible by Medicare
Early colon cancer or colorectal cancer diagnosis was made possible by changes in Medicare reimbursement policy few years back. The study was published by Yale School of Medicine researchers in the December issue of Journal of the American Medical Association (JAMA). The study was funded by a Beeson Career Development Award to Gross, and by the Claude D. Pepper Older Americans Independence Center at Yale.
Osteoporosis :: Women on osteoporosis drug can discontinue use with no risk
A long-term study of the most widely used osteoporosis drug has found that many women can discontinue the drug after five years without increasing their fracture risk for as long as five more years.
Gene :: Cancer genes to better and earlier detection of lung, breast, prostate and colon cancer
A research team at UT Southwestern Medical Center has for the first time identified several genes whose expression is lost in four of the most common solid human cancers — lung, breast, prostate and colon cancer.
Stem Cell :: Stem cells as cancer therapy
It is widely hoped that neural stem cells will eventually be useful for replacing nerves damaged by degenerative diseases like Alzheimer disease and multiple sclerosis. But there may also be another use for such stem cells — delivering anti-cancer drugs to cancer cells.
Malaria :: Erythrocyte G protein a novel target for malarial chemotherapy
Kasturi Haldar and colleagues from Northwestern University Medical School, Chicago, investigated a protein in red blood cells (erythrocyte guanine nucleotide regulatory protein Gs) as a novel antimalarial target.
Immunity :: Molecular on/off switch controls immune defenses against viruses
Much like flipping a light switch, the hepatitis C virus turns on human immune defenses upon entering the body but also turns off those defenses by manipulating interaction of key cellular proteins, UT Southwestern Medical Center researchers have found.
Stroke :: Methamphetamine use increases risks of artery tears and stroke
Methamphetamine use may be associated with increased risks of major neck artery tears and stroke, according to an article published in the December 26, 2006, issue of Neurology, the scientific journal of the American Academy of Neurology.
Health Care :: Bill on parity in health care, health insurance coverage for mental illnesses
Governor George E. Pataki signed legislation to enact Timothy’s Law, which will require insurance companies to provide health insurance coverage for individuals with mental illnesses. The new law is named after Timothy O’Clair, a 12-year old boy from Schenectady County who had an emotional disorder, but was unable to obtain mental health services under his parent’s health insurance coverage. Timothy completed suicide in March 2001.
Lung Cancer :: Quitting cigarettes helps lung cancer
Once people have been diagnosed with lung cancer they might think it pointless to stop smoking, but in fact it’s not too late to benefit from quitting, a new study shows.
