U of T researchers reveal Epstein-Barr virus protein contributes to cancer
Researchers at the University of Toronto have discovered that the EBNA1 protein of Epstein-Barr virus (EBV) disrupts structures in the nucleus of nasopharyngeal carcinoma (NPC) cells, thereby interfering with cellular processes that normally prevent cancer development.   view more (2008-10-07)

Study: Bird diversity lessens human exposure to West Nile Virus
A study by biologists at Washington University in St. Louis shows that the more diverse a bird population is in an area, the less chance humans have of exposure to West Nile Virus (WNV).    view more (2008-10-07)

Study confirms colonoscopy associated with reduced colorectal cancer incidence
Patients who undergo a complete negative colonoscopy have a reduced incidence of colorectal cancer, confirms a study published in Clinical Gastroenterology and Hepatology.   view more (2008-10-03)

Urbanization in Africa at dawn of 20th century marked outbreak of HIV
New research indicates that the most pervasive global strain of HIV began spreading among humans between 1884 and 1924, suggesting that growing urbanization in colonial Africa set the stage for the HIV/AIDS pandemic.   view more (2008-10-02)

New findings indicate HIV/AIDS pandemic began around 1900, earlier than previously thought
New research indicates that the most pervasive global strain of HIV began spreading among humans between 1884 and 1924, not during the 1930s, as previously reported.   view more (2008-10-02)

MU scientists 'see' how HIV matures into an infection
After improving the sensitivity of nuclear magnetic resonance (NMR), researchers at the University of Missouri actually watched the HIV-1 protease mature from an inactive form into an active infection. This process has never been directly visualized before. The findings appear today in the journal... view more (2008-10-02)

HIV drug maraviroc effective for drug-resistant patients
As many as one quarter of HIV patients have drug resistance, limiting their treatment options and raising their risk for AIDS and death.   view more (2008-10-02)

Childhood wheezing with rhinovirus can increase asthma odds 10-fold
Infants who experience viral respiratory illnesses with wheezing are known to be at increased risk for developing asthma later during childhood.   view more (2008-10-01)

Hay fever may be best treated with self-adjusted dosing
Hay fever, the often seasonal allergy that affects between 10 and 20 percent of the American population, is best controlled through a course of patient-adjusted dosing.   view more (2008-10-01)

Hepatitis B exposure may increase risk for pancreatic cancer
In a first-of-its-kind finding, researchers at The University of Texas M. D. Anderson Cancer Center have discovered that exposure to the hepatitis B virus (HBV) may increase the risk of pancreatic cancer.   view more (2008-09-30)

Study finds association between hepatitis B and pancreatic cancer
A new study has shown that evidence of past hepatitis B infection was twice as common in people with pancreatic cancer than in healthy controls. This study is the first to report an association between past exposure to the hepatitis B virus and pancreatic cancer, but researchers cautioned that more... view more (2008-09-30)

Scientists unmask key HIV protein, open door for more powerful AIDS drugs
University of Michigan scientists have provided the most detailed picture yet of a key HIV accessory protein that foils the body's normal immune response.   view more (2008-09-29)

New way to control protein activity could lead to cancer therapies
Investigators at the Stanford University School of Medicine have found a way to quickly and reversibly fine-tune the activity of individual proteins in cells and living mammals, providing a powerful new laboratory tool for identifying - more precisely than ever before - the functions of different... view more (2008-09-29)

Deadly rugby virus spreads in sumo wrestlers
Rugby players may get more than just the ball out of a scrum - herpes virus can cause a skin disease called "scrumpox" and it spreads through physical contact.   view more (2008-09-29)

'Hub' of fear memory formation identified in brain cells
A protein required for the earliest steps in embryonic development also plays a key role in solidifying fear memories in the brains of adult animals, scientists have revealed. An apparent "hub" for changes in the connections between brain cells, beta-catenin could be a potential target... view more (2008-09-29)

Researchers find animal with ability to survive climate change
Queen's researchers have found that the main source of food for many fish - including cod - in the North Atlantic appears to adapt in order to survive climate change.   view more (2008-09-24)

Pitt research indicates new virus is culprit, not bystander, in deadly skin cancer
University of Pittsburgh scientists are uncovering more evidence that a virus they recently discovered is the cause of Merkel cell carcinoma, an aggressive and deadly form of skin cancer.   view more (2008-09-23)

Extinct may not be forever for some species of Galapagos tortoises
Yale scientists report that genetic traces of extinct species of Galapagos tortoises exist in descendants now living in the wild, a finding that could spur breeding programs to restore the species, The report appears in Proceedings of the National Academy of Sciences.   view more (2008-09-23)

Study examines cost-effectiveness of HIV monitoring strategy in countries with limited resources
In a computer-based model evaluating the benefits and costs of three types of HIV disease monitoring strategies, early initiation of antiretroviral therapy and monitoring using the CD4 count, a measure of immune system function, instead of based on symptoms appear to provide health benefits in low-... view more (2008-09-22)

Geriatric patients receive significant benefit from cochlear implantation
Despite previous inconclusive research, geriatric patients do experience significant quality of life improvement (QOL) after receiving cochlear implants for hearing loss, says new research presented at the 2008 American Academy of Otolaryngology - Head and Neck Surgery Foundation (AAO-HNSF) Annual... view more (2008-09-22)

New mechanism for cardiac arrhythmia discovered
It has long been thought that virus infections can cause cardiac arrhythmia. But why has not been understood. Ulrike Lisewski, Dr. Yu Shi, Michael Radke and Professor Michael Gotthardt of the Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch, Germany, have now discovered the... view more (2008-09-18)

Why some primates, but not humans, can live with immunodeficiency viruses and not progress to AIDS
Key differences in immune system signaling and the production of specific immune regulatory molecules may explain why some primates are able to live with an immunodeficiency virus infection without progressing to AIDS-like illness, unlike other primate species, including rhesus macaques and humans,... view more (2008-09-17)

Herpes drug inhibits HIV in patients infected with both viruses
Researchers at the U.S. National Institutes of Health (NIH), McGill University and other institutions have discovered how a simple antiviral drug developed decades ago suppresses HIV in patients who are also infected with herpes.   view more (2008-09-16)
