HIV drug resistance spreading in China, researcher says

As HIV spreads beyond high-risk groups into China's general population, drug-resistant strains of the virus also are appearing in parts of the country, Chen Zhiwei of the AIDS Institute in Hong Kong said recently, Reuters reports.

Ultrafast photodynamics of DNA

DNA, the molecule that acts as the carrier of genetic information in all forms of life, is highly resistant against alteration by ultraviolet light, but understanding the mechanism for its photostability presents some puzzling problems. A key aspect is the interaction between the four chemical bases that make up the DNA molecule.

Abdominal venous thrombosis risk factors

Abdominal venous thrombosis may present as BCS or SVT. Hereditary and acquired risk factors have been implicated in the etiopathogenesis of abdominal venous thrombosis.

Ultra-sensitive nanoprobes help tackle MRSA

This week Nature Nanotechnology journal (October 12th) reveals how scientists from the London Centre for Nanotechnology (LCN) at University College London are using a novel nanomechanical approach to investigate the workings of vancomycin, one of the few antibiotics that can be used to combat increasingly resistant infections such as methicillin-resistant Staphylococcus aureus (MRSA).

Battling cancer at the single cell level

New research suggests that the identification and examination of key cell signaling events required for initiation and progression of cancer might be best accomplished at the single cell level. The research, published by Cell Press in the October issue of the journal Cancer Cell, provides new insight that may lead to better diagnosis and treatment of some complex cancers.

100 years of HIV in humans

HIV has existed among human populations for about 100 years, decades earlier than previously believed, according to a study published Wednesday in the journal Nature, the Los Angeles Times reports (Engel, Los Angeles Times, 10/2).

Researchers discover genes linked to increased gout risk

A team of researchers from the United States and the Netherlands has identified mutations in three genes that are associated with high levels of uric acid in the blood, which is a risk factor for gout.

Statin-induced muscle disorders are focus of $2.5 million in grants from NIH

Approximately 200,000 of the 38 million people in the U.S. who take statins to treat high cholesterol may develop life-threatening muscle disease.

Short RNAs show a long history

MicroRNAs, the tiny molecules that fine-tune gene expression, were first discovered in 1993. But it turns out they've been around for a billion years.

Discovery of genetic link between obesity and colon cancer risk

A new study reveals the first-ever genetic link between obesity and colon cancer risk, a finding that could lead to greater accuracy in testing for the disease, said a researcher at the University of Alabama at Birmingham (UAB).

New test for rapid detection of influenza

The Association of Public Health Laboratories (APHL) collaborated with the Centers for Disease Control and Prevention (CDC) in the development of a new test for influenza, which received 510(k) clearance today by the Food and Drug Administration (FDA).

A DNA-based vaccine shows promise against avian flu

Though it has fallen from the headlines, a global pandemic caused by bird flu still has the United States' Centers for Disease Control and Prevention on high alert. Yet, to date, the only vaccines that have proven even semi-effective are produced in chicken eggs, take five to six months to prepare and act against a single variant of the H5N1 virus, which mutates incredibly quickly.

Multiple sclerosis patients have higher spinal fluid levels of suspicious immune molecule

A protein that helps keep immune cells quiet is more abundant in the spinal fluid of patients with multiple sclerosis (MS), further boosting suspicion that the protein, TREM-2, may be an important contributor to the disease.

Breast, ovarian cancer prediction models more accurate for white women than Asian-American women

Two widely used prediction models for identifying a woman's risk for breast and ovarian cancer appear to be less reliable for Asian-American women compared with white women, according to a study in the October issue of the Journal of Clinical Oncology, Reuters Health reports.

New pig model of cystic fibrosis provides better understanding of human disease

For the first time, researchers have developed a genetically altered animal model for cystic fibrosis (CF) that closely matches the characteristics of the disease in humans. By studying the complex and multi-organ disease process in the pig model, researchers can now better understand how the complications of CF develop, an advancement that may lead to new avenues for research in prevention and treatment.
