Biological factors, cell behavior drive tumor growth contributing to therapy failure and relapse
The Medical News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Cancer scientists led by Dr. John Dick at the Princess Margaret Cancer Center have found a way to follow single tumor cells and observe their growth over time. By using special immune-deficient mice to propagate human colorectal cancer, they found that genetic mutations, regarded by many as the chief suspect driving cancer growth, are only one piece of the puzzle. The team discovered that biological factors and cell behavior — not only genes — drive tumor growth, contributing to therapy failure and relapse. More

CDC links norovirus to most gastroenteritis outbreaks
Medscape Medical News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Norovirus caused most acute gastroenteritis outbreaks resulting from person-to-person contact during 2009 to 2010, the majority of which occurred in long-term care facilities, according to an article published online in the Morbidity and Mortality Weekly Report. Mary E. Wikswo, MPH, and Aron J. Hall, DVM, from the Division of Viral Diseases, National Center for Immunization and Respiratory Diseases, Centers for Disease Control and Prevention, Atlanta, Georgia, conducted the first analysis of AGE outbreaks reported to the National Outbreak Reporting System, which was launched in 2009.

Adoptive cell transfer: New technique could make cell-based immune therapies for cancer safer, more effective
Memorial Sloan-Kettering Cancer Center via Medical Xpress    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A team led by Dr. Michel Sadelain, director of the Center for Cell Engineering at Memorial Sloan-Kettering Cancer Center, has shown for the first time the effectiveness of a new technique that could allow the development of more-specific, cell-based immune therapies for cancer. Their findings were reported online in Nature Biotechnology. More

Decline in physician-owned independent practices means independent clinical laboratories need to shift strategy
Dark Daily    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Change in who owns office-based physician groups is a trend that can create new winners and losers among the nation's independent medical laboratories. Physicians today are more willing to practice medicine as employees than as partners or owners of their medical group. This signals a significant shift in the market for clinical laboratory testing and anatomic pathology services. More

Controversial bird flu work to resume soon
NPR    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Flu researchers may be close to ending an unusual moratorium on some controversial scientific work that has lasted almost a year. That's because officials at the National Institutes of Health say they will be moving swiftly to finalize a new process for deciding whether or not to fund proposed experiments that could potentially create more dangerous forms of the bird flu virus H5N1.

Antibiotics based on a new principle may defeat MRSA
Karolinska Institute via Medical Xpress    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Scientists at Karolinska Institute in Sweden have presented a new principle for fighting bacterial infections — in other words, a new type of antibiotic, in the FASEB Journal. The new antibiotic mechanism is based on selectively blocking the thioredoxin system in the cells, which is crucial to the growth of certain bacteria. Scientists hope to be able to treat such conditions as stomach ulcers, TB and MRSA. More

CDC: Chlamydia, gonorrhea cases increasing
USA Today    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Reports of infections from sexually transmitted diseases are increasing among certain groups, according to government data. In 2011, 1.4 million chlamydia infections were reported to the Centers for Disease Control. The rate of cases per 100,000 people increased 8 percent, to 457.6 in 2011 from 423.6 in 2010. The CDC reported 321,849 gonorrhea infections. The rate increased 4 percent to 104.2 cases per 100,000 in 2011 from 100.2 in 2010. More

Spread of cancer cells may be slowed by targeting of protein
R&D Magazine    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The spread of cancer cells may be slowed by targeting the protein km23-1, according to researchers at Penn State University College of Medicine. A motor protein that transports cargo within the cell, km23-1 is also involved in the movement or migration of cells. Migration is necessary for cancer to spread, so understanding this cell movement is important for development of better cancer treatments. More

Research leads to detection of smallest virus particle, implications for early treatment of disease
The City University of New York via PhysOrg    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Work by researchers at The City University of New York has made it possible, for the first time, to detect the smallest virus particle. Since even one viral particle can represent a deadly threat, the research likely will make an important contribution to ongoing research on early detection of such diseases as AIDS and cancer. More

Nanotechnology enables creation of biomarkers for cancer detection
FierceHealthIT    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Massachusetts Institute of Technology researchers developed new technology, which enables the creation of biomarkers to diagnose cancer earlier, according to a recent study. Researchers used nanoparticles — originally intended as imaging agents for tumors — to instead interact with enzymes known as proteases, MIT news reports. That interaction, in turn, creates biomarkers, detected in a patient's urine. More

Medical examiner wants to probe Sandy Hook shooter's genetics
The Huffington Post    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Connecticut's chief medical examiner said he hopes Adam Lanza's biology will help explain why the Sandy Hook shooter went on a deadly rampage. The Hartford Courant reports that Dr. H. Wayne Carver has asked a geneticist at the University of Connecticut to join in his investigation of the killings. More
