Relationship between obesity prevalence and growth of supermarket economy

An international team of researchers' study of the spatial patterns of the spread of obesity suggests America's bulging waistlines may have more to do with collective behavior than genetics or individual choices. The team, led by City College of New York physicist Hern-n Makse, found correlations between the epidemic's geography and food marketing and distribution patterns.

Study strengthens link between HHV-6B and mesial temporal lobe epilepsy

A ten-year NIH-funded study has determined that a third of infants with prolonged seizures and fever suffer from either a new or reactivated roseola virus infection. Roseola viruses are the cause of the common childhood rash, but can also cause limbic encephalitis, a condition that frequently progresses to epilepsy. Investigators discovered one of the roseola viruses, human herpesvirus-6B (HHV-6B) in the blood of 32% of 169 infants with prolonged seizures, a condition known as status epilepticus.

Breast milk protects against oral transmission of HIV

More than 15 percent of new HIV infections occur in children. Without treatment, only 65 percent of HIV-infected children will live until their first birthday, and fewer than half will make it to the age of two. Although breastfeeding is attributed to a significant number of these infections, most breastfed infants are not infected with HIV, despite prolonged and repeated exposure.

Theraclone Sciences commences TCN-202 Phase 1 trial in CMV infection

Theraclone Sciences, Inc., a therapeutic antibody discovery and development company, announced today first dosing of subjects in a Phase 1 clinical trial of TCN-202, a broadly protective, fully human monoclonal antibody in development for the treatment of human cytomegalovirus (CMV) infection.

Single protein determines persistence of viral infection

Scientists from The Scripps Research Institute have shown a single protein can make the difference between an infection clearing out of the body or persisting for life. The results also show where the defects occur in the immune system without the protein and offer the possibility that targeting this signaling pathway could be beneficial for treatment of persistent viral infections in humans.

Researchers identify primary player of the biochemical bugle call

Researchers have identified the primary player of the biochemical bugle call that musters the body's defenders against viral infection.

Reovirus can trick the body's defenses to reach and kill cancer cells

Scientists have shown how a promising viral therapy that delivers a double blow to cancer can sneak up on tumors undetected by hitching a ride on blood cells.

New chemical-screening method can discover compounds against HIV

Scientists at The Scripps Research Institute have used a powerful new chemical-screening method to find compounds that inhibit the activity of human immunodeficiency virus (HIV), the virus that causes AIDS.

Roseola virus accounts for one third of febrile status epilepticus cases

New research shows that human herpesviruses (HHV)-6B and HHV-7, commonly know as roseola virus), account for one third of febrile status epilepticus (FSE) cases. Results of the FEBSTAT prospective study now available in Epilepsia, a journal published by Wiley-Blackwell on behalf of the International League Against Epilepsy (ILAE), suggest that HHV-6B may be involved in the development of epilepsy and further research is urgently needed.

Child Survival Call to Action event signals a 'hopeful moment' in global health

"Helping mothers give birth to HIV-free children is an essential piece of the puzzle of ending preventable child deaths," U.S. Global AIDS Coordinator Ambassador Eric Goosby writes in this post in the AIDS.gov blog, adding, "Yet 390,000 infants around the globe were born with the virus in 2010."

HLA B-27 protein appears to confer ability to suppress HIV viral replication

The rare ability of some individuals to control HIV infection with their immune system alone appears to depend - at least partially - on specific qualities of the immune system's killer T cells and not on how many of those cells are produced.

VaxInnate commences VAX161 Phase I trial in pandemic avian influenza

VaxInnate Corporation today announced that enrollment has commenced in a Phase I clinical trial to evaluate VAX161, its novel H5 vaccine candidate in development for the prevention of pandemic avian influenza or bird flu. VaxInnate is a biotechnology firm pioneering breakthrough technology for developing novel vaccines.

New data on individuals with natural ability to fight off AIDS

"Scientists on Sunday said they had found a key piece in the puzzle as to why a tiny minority of individuals infected with HIV have a natural ability to fight off the deadly AIDS virus," Agence France-Presse reports.

Cellular source of cervical cancer found

A team of scientists from A*STAR's Institute of Medical Biology (IMB) and Genome Institute of Singapore (GIS) together with clinicians from Boston's Brigham and Women's Hospital (BWH) have identified a unique set of cells in the cervix that are the cause of human papillomaviruses (HPV) related cervical cancers. Significantly, the team also showed that these cells do not regenerate when excised.

Hepatitis C more prevalent among homeless adults in downtown Los Angeles

Recent government studies show that hepatitis C, which can destroy the liver and necessitate a liver transplant, now kills more American adults than AIDS, and new UCLA research shows just how prevalent the disease is among homeless adults in downtown Los Angeles.

VOA reports on global polio vaccination challenges

"International health experts say the global campaign to eradicate polio has reached a critical stage, with Afghanistan, Pakistan and Nigeria the only countries where the crippling and potentially deadly virus is still prevalent," VOA News reports.

Subtype of CD4-positive immune cells in the gut may influence HIV infection outcome

The findings of a new study in monkeys may help clarify why some people infected with HIV are better able to control the virus. They also may pinpoint a target for treatment during early HIV infection aimed at increasing the supply of certain immune cells in the gut, which the study shows could be an important factor in limiting HIV growth in cells throughout the body.

Biomedical engineers develop SMART detector for flu diagnosis

In April 2009, the world took notice as reports surfaced of a virus in Mexico that had mutated from pigs and was being passed from human to human. The H1N1 "swine flu," as the virus was named, circulated worldwide, killing more than 18,000 people, according to the World Health Organization. The Centers for Disease Control and Prevention in the United States said it was the first global pandemic in more than four decades.
