Bridgepoint Health, a canadian hospital in Toronto’s east end says it will remain closed to visitors and new patients until later this week following an outbreak of the highly contagious Norwalk virus.
Bioengineers and public health researchers at Harvard University have developed a novel spraying method for delivering the most common tuberculosis (TB) vaccine, providing a new low-cost and scaleable technique that offers needle-free delivery and greater stability at room temperature than existing methods.
The primary targets of HIV-1 infection in the human vagina have been definitively identified in a new study published in the February 2007 issue of the journal Immunity, published by Cell Press. The findings are likely to guide development of new strategies that will prevent HIV-1 transmission.
A featured paper in the Feb. 14 issue of Nature Cancer Gene Therapy demonstrates that cancer cells in the liver are excellent targets for gene therapy using adenoviral vectors, based upon a fundamental new understanding of the differences between cancerous and normal liver cells. The findings signal a new way to treat cancers that have spread to the liver, such as metastatic cancers of the colon and breast.
In a finding that could have profound implications for AIDS vaccine design, researchers led by a team at the NIAID have generated an atomic-level picture of a key portion of an HIV surface protein as it looks when bound to an infection-fighting antibody. Unlike much of the constantly mutating virus, this protein component is stable and — more importantly, say the researchers — appears vulnerable to attack from this specific antibody, known as b12, that can broadly neutralize HIV.
Bioengineers and public health researchers have developed a novel spray drying method for preserving and delivering the most common tuberculosis (TB) vaccine. The low-cost and scaleable technique offers several potential advantages over conventional freezing procedures, such as greater stability at room temperature and use in needle-free delivery.
Australian scientists are raising concerns over the unpredictable nature of a contraceptive vaccine that aims to control populations of wild animals, such as rabbits and foxes.
Researchers at the University of Pennsylvania School of Medicine are the first to show that a mouse protein, whose human equivalent is related to defense against HIV-1, inhibits the infection and spread of a mouse tumor virus.
Four million people die every year from respiratory diseases such as viral influenza. For elderly people in particular, an infection can be dangerous.
Rift Valley Fever (RVF), a deadly viral disease that broke out in Kenya in late 2006, has spread to neighbouring Tanzania, where two deaths have been reported in the northern region of Arusha, a government official said Tuesday.
