First-of-its-kind study shows supervised injection facilities can help people quit drugs

A study led by researchers at the BC Centre for Excellence in HIV/AIDS (BC-CfE) at St. Paul's Hospital and the University of British Columbia has found that supervised injection facilities such as Vancouver's Insite connect clients with addiction treatment, which in turn resulted in greater likelihood of stopping injection drug use for at least six months.

The study, recently published in the peer-reviewed journal Drug and Alcohol Dependence, is the first ever to examine the link between a supervised injection facility and injection cessation.

Manatee subspecies genetically confirmed, but diversity challenge looms

Gainesville, FL. -- The first genetic study to compare nuclear DNA of endangered Antillean manatees in Belize with Florida manatees confirmed their designation as separate subspecies. Belize's manatees, however, were found to have extremely low genetic diversity, raising questions about their long-term genetic viability.

The Central American country of Belize hosts the largest known breeding population of Antillean manatees and is touted by biologists for its potential to repopulate other parts of Central America where manatees are severely reduced, rare or absent.

A new target in polycystic kidney disease

In work suggesting a new approach to treating polycystic kidney disease (PKD), a leading cause of kidney failure, researchers at Children's Hospital Boston were able to block the formation of fluid-filled cysts, the hallmark of the disease, in a mouse model. Their findings, using a compound that inhibits a receptor known as c-Met, will be published in the September 13th online edition of the Journal of Clinical Investigation.

NYU Langone scientists find key pathway implicated in progression of childhood cancer

New York (September 13, 2010) - A protein crucial for the immune response appears to be a key player in the progression of a devastating form of childhood leukemia called T-cell acute lymphoblastic leukemia (T-ALL). Suppressing the activity of the protein kills the leukemic cells, the study shows, opening a potential avenue to new drugs that could prevent progression of the disease.

Lung cancer culprit could offer target for therapy, UT Southwestern researchers report

DALLAS – Sept. 13, 2010 – A tiny molecule that spurs the progression of non-small-cell lung cancer could become a player in fighting the disease, say researchers at UT Southwestern Medical Center, who published a study on how the molecule behaves in mice in the Sept. 14 issue of Cancer Cell.

Female marine snails trick amorous males

Female marine snails trick amorous males

Sexual conflict is not only a human phenomenon. Scientists at the University of Gothenburg have shown that females of the rough periwinkle conceal their gender identity in order to avoid excessive copulation.

Life cycle of proteins captured on film

Our bodies recycle proteins, the fundamental building blocks that enable cell growth and development. Proteins are made up of a chain of amino acids, and scientists have known since the 1980s that first one in the chain determines the lifetime of a protein. McGill researchers have finally discovered how the cell identifies this first amino acid – and caught it on camera.

Sorghum bran has more antioxidants than blueberries and pomegranates - study

Athens, Ga. - A new University of Georgia study has found that select varieties of sorghum bran have greater antioxidant and anti-inflammatory properties than well-known foods such as blueberries and pomegranates.

Researchers measured polyphenolic compounds, which naturally occur in plants to help fight against pests and disease, and found that the black and sumac varieties of sorghum have significant levels of antioxidants. Many fruits also contain these compounds, they said, though sorghum bran may prove to be the richest and cheapest source.

Scientists 'clone' human virus

A team of Welsh scientists have successfully cloned a human virus offering new hope for the treatment of potentially life-threatening diseases.

Human cytomegalovirus (HCMV) is a major infectious cause of congenital malformations worldwide. The virus is also known to cause life-threatening disease in transplant patients and people with HIV/AIDS.

The development of new treatments has been hampered as scientists have been unable to stably replicate HCMV outside the human body.

Louisiana Tech forestry professor helps to shape future of global industry research

RUSTON, La – Dr. Bogdan Strimbu, assistant professor of biometrics and quantitative silviculture at Louisiana Tech University's School of Forestry, recently organized and conducted a technical session at the International Union of Forest Research Organization's (IUFRO) XXIII World Congress in Seoul, South Korea.

USGI medical tissue anchors show durability beyond 1 year

SAN CLEMENTE, Calif. (September 13, 2010) – USGI Medical, Inc., the Incisionless Surgery company, today announced that updated multi-center results confirm durability of the company's Expandable Tissue Anchors™ up to a year or more in a variety of incisionless gastrointestinal (GI) procedures, including use of a ROSE procedure (Repair of Surgery, Endolumenal) to repair dilated tissue after gastric bypass.

Nature's gift for gardening may hold key to biodiversity

Gardeners are used to cross-breeding flowers to produce pretty petals or sweet scents – now scientists have shown the importance of nature's talent for producing new types of flowers.

DNA analysis of wild evergreen rhododendrons in the Himalayas has suggested that hundreds of species of the plant could be derived from hybrids – cross-breeds between different species.

New insights provide promise for development of tools to protect damaged tissues

St. Jude Children's Research Hospital investigators have identified a novel structure in cells that serves as a control switch in the body's system for eliminating damaged cells and also offers new therapeutic potential.

The findings provide fresh insight into the machinery at work as cells ramp up production of p53 protein following DNA damage. The p53 protein plays a critical role in how cells respond to the stress that damages DNA. The gene that carries instructions for making p53 protein is the most commonly mutated gene in human cancers.

Breakthrough in drug trial offers hope for heart attack patients

New findings from a major drug trial have brought experts a step closer to developing a drug which could prevent thousands of British deaths from heart attacks.

Dr Robert Storey, Reader at the University of Sheffield and Consultant Cardiologist at Sheffield Teaching Hospitals, was the UK lead for international trials of a new drug, ticagrelor, which have been taking place over the last six years.
