Gene Therapy Protects Against Pandemic Flu Strains

May 30, 2013 11:21 am | News | Comments

Researchers have developed a new gene therapy to thwart a potential influenza pandemic. Investigators demonstrated that a single dose of an adeno-associated virus (AAV) expressing a broadly neutralizing flu antibody into the nasal passages of mice and ferrets gives them complete protection and substantial reductions in flu replication when exposed to lethal strains of H5N1 and H1N1 flu virus.

Nanoparticles Shape-shift in Response to Tumor Signal

May 29, 2013 11:28 am | News | Comments

Scientists have designed tiny spherical particles to float easily through the bloodstream after injection, then assemble into a durable scaffold within diseased tissue. An enzyme produced by a specific type of tumor can trigger the transformation of the spheres into netlike structures that accumulate at the site of a cancer.

UK Measles Surge Years After Vaccine Scare

May 20, 2013 6:00 am | by MARIA CHENG - AP Medical Writer - Associated Press | News | Comments

More than a decade ago, British parents refused to give measles shots to at least a million children because of a vaccine scare that raised the specter of autism. Now, health officials are scrambling to catch up and stop a growing epidemic of the contagious disease. This year, the U.K. has had more than 1,200 cases of measles, after a record number of nearly 2,000 cases last year.

WHO says single yellow fever shot is enough

May 17, 2013 3:55 am | by The Associated Press | News | Comments

The World Health Organization says a yellow fever booster vaccination given 10 years after the initial shot isn't necessary. The U.N.'s global health agency said Friday that its expert group on immunization believes a single dose of vaccination is sufficient to confer lifelong immunity against the disease.

Nanogel Secretes Insulin on Demand

May 16, 2013 11:49 am | News | Comments

Injectable nanoparticles developed at MIT may someday eliminate the need for patients with Type 1 diabetes to constantly monitor their blood-sugar levels and inject themselves with insulin. The nanoparticles were designed to sense glucose levels in the body and respond by secreting the appropriate amount of insulin, thereby replacing the function of pancreatic islet cells, which are destroyed in patients with Type 1 diabetes.

New Drug Slows Alzheimer's

May 15, 2013 10:17 am | News | Comments

A drug developed by scientists at the Salk Institute for Biological Studies, known as J147, reverses memory deficits and slows Alzheimer's disease in aged mice following short-term treatment. The findings may pave the way to a new treatment for Alzheimer's disease in humans.

India to Offer $1 Rotavirus Vaccine

May 14, 2013 7:43 am | by The Associated Press | News | Comments

The Indian government announced the development of a new low-cost vaccine proven effective against a diarrhea-causing virus that is one of the leading causes of childhood deaths across the developing world. The Indian manufacturer of the new rotavirus vaccine pledged to sell it for $1 a dose, a significant discount from the cost of the current vaccines on the market.
