Scientists discover repair mechanism of photolyase in sun damaged DNA

Researchers have long known that humans lack a key enzyme one possessed by most of the animal kingdom and even plants that reverses severe sun damage.For the first time, researchers have witnessed how this enzyme works at the atomic level to repair sun-damaged DNA.The discovery holds promise for future sunburn remedies and skin cancer prevention.

New model of inflammatory bowel disease explores interactions of cells in immune system

Scientists at the Virginia Bioinformatics Institute at Virginia Tech have constructed a mathematical and computational model of inflammatory bowel disease that allows researchers to simulate the cellular and molecular changes underlying chronic inflammation in humans. The model allows scientists to explore different interactions of cells in the immune system, check how these cells are linked to inflammation in the colon, and identify intervention points to perhaps stop the disease in its tracks.

Study identifies infection mechanism of disease-causing microbes

A study published in the July 23 issue of Cell identifies the mechanism used by several types of common, virulent microbes to infect plants and cause devastating blights. Microbes using this infection mechanism include fungi that are currently causing wheat rust epidemics in Africa and Asia, and a class of parasitic algae, called oomycetes, that resulted in the Irish potato blight of the 19th Century. These microbes remain an agricultural scourge today.

hBD-3 biomarker helps early stage detection of oral cancer

Detecting oral cancer in its earliest stages can save the lives of the nearly 40,500 people diagnosed annually. But early detection has been difficult. Case Western Reserve University School of Dental Medicine researchers discovered a biomarker, called human beta defensin-3 (hBD-3), which may serve as an early warning. The defensin is present in all oral cancers and associated with the early stages of oral cancer.

New carbon nanomaterial fights disease causing bacteria

A new form of paper with the built-in ability to fight disease-causing bacteria could have applications that range from anti-bacterial bandages to food packaging that keeps food fresher longer to shoes that ward off foot odor. A report about the new material, which consists of the thinnest possible sheets of carbon, appears in ACS Nano, a monthly journal.

Smoking cessation effectively alter subgingival microbiome in patients on periodontal therapy: Study

Patients with chronic gum disease who quit smoking in addition to undergoing nonsurgical therapy not only demonstrated a lower abundance of harmful oral pathogens, but also an increase in health-associated bacteria. The researchers from The Ohio State University, Columbus Ohio, and Newcastle University, United Kingdom report their findings in the July 2010 issue of the Journal of Clinical Microbiology.

NovaBay reports positive results from NVC-422 Phase 2a proof-of-concept clinical trial for impetigo

NovaBay Pharmaceuticals, Inc. today announced that its lead product candidate was safe and efficacious against the highly contagious skin infection impetigo in a Phase 2a proof-of-concept clinical trial. This dose-ranging study showed that the drug cleared impetigo infections, including those in the trial caused by a drug-resistant strain of bacteria called methicillin-resistant Staphylococcus aureus or MRSA. Impetigo afflicts approximately 1 million people, primarily infants and children, in the United States annually.

Researchers identify a substance that protects farm children from allergies, allergic asthma

Researchers from Bochum have isolated the substance in cowshed dust that possibly protects farm children from developing allergies and allergic asthma, namely the plant sugar molecule arabinogalactan. If high concentrations thereof are inhaled during the first year of life it inhibits the immune system from excessive defense reactions.

Benefits of drug L-methionine for neurogenic bladder disorders unclear

It is unclear whether patients with neurogenic bladder disorders benefit from the drug L-methionine. The only study currently available provides neither proof of benefit nor proof of harm. This is the result of a report published by the German Institute for Quality and Efficiency in Health Care (IQWiG) on 12 July 2010.

Pneumococcal conjugate vaccine appears to reduce pneumonia, serious complications in infants: Research

A pneumococcal conjugate vaccine introduced in the U.S. 10 years ago appears to reduce pneumonia and serious associated complications, such as blood infections, in the vaccine's target range, children less than a year old, according to new research.

Study on how cellular defence systems keep themselves in check from damaging cells themselves

When cells are attacked by bacteria they use all means at their disposal to defend themselves. But cellular defence systems can damage the cells themselves and so need to be kept tightly in check. Recent results help us to understand how this is done and give pointers to new ways of combating disease. Matthias Farlik in the group of Thomas Decker at the Centre for Molecular Biology of the University of Vienna (Max F. Perutz Laboratories) and Mathias Müller of the University of Veterinary Medicine, Vienna have published these findings in the current issue of the journal "Immunity".
