Canadian experts on irritable bowel syndrome

While more than six per cent of Canadians suffer from this troublesome disease - characterized by on-going abdominal pain, discomfort, bloating, and severe bouts of either diarrhoea or constipation - most Canadians, including many physicians, know little about it.

South Australian hospital battles to contain superbug VRE

The cancer ward at the Royal Adelaide Hospital (RAH) in South Australia is currently battling to cope with an antibiotic-resistant bacteria called Vanocomycin-resistant Enterococci (VRE), a form of bacteria which lives in the gut.

Evidence grows that maternal immune response to fetal brain during pregnancy a key factor in some autism

New studies in pregnant mice using antibodies against fetal brains made by the mothers of autistic children show that immune cells can cross the placenta and trigger neurobehavioral changes similar to autism in the mouse pups.

Tijuana injection drug users on collision course for HIV and tuberculosis

A study by researchers from the University of California, San Diego School of Medicine, in collaboration with Mexican researchers and health officials, shows that as many as 67 percent of injection drug users in Tijuana test positive for tuberculosis (TB) infection.

Separating the good from the bad

Scientists at MIT and Brown University studying how marine bacteria move recently discovered that a sharp variation in water current segregates right-handed bacteria from their left-handed brethren, impelling the microbes in opposite directions.

Rib-X granted patent for novel oxazolidinone in China

Rib-X Pharmaceuticals, Inc. ("Rib-X" or the "Company"), a development-stage company focused on the discovery and development of novel antibiotics for the treatment of antibiotic-resistant infections, today announced the issuance of a key antibiotic patent in China.

Some orthodontic appliances more prone to bacteria

Researchers at the Oregon Health & Science University School of Dentistry have found the majority of patients with self-ligating orthodontic brackets retain fewer bacteria in plaque than patients with elastomeric orthodontic brackets.

Gene targeting discovery opens door for vaccines and drugs

In a genetic leap that could help fast track vaccine and drug development to prevent or tame serious global diseases, DMS researchers have discovered how to destroy a key DNA pathway in a wily and widespread human parasite.

Colon cancer shuts down receptor that could shut it down

Though a high-fiber diet has long been considered good for you and beneficial in staving off colon cancer, Medical College of Georgia researchers have discovered a reason why: roughage activates a receptor with cancer-killing potential.

Study finds multidrug-resistant gram-negative bacteria high in long-term care

The prevalence of a certain form of drug-resistant bacteria, called multidrug-resistant gram-negative (MDRGN) organisms, far surpassed that of two other common antimicrobial-resistant infections in long-term care facilities, according to a study conducted by researchers at Hebrew SeniorLife's Institute for Aging Research.

Researchers model 3D structures of proteins that control human clock

In an Early Edition issue of The Proceedings of the National Academy of Sciences (PNAS) on April 9, 2009, the researchers report that they have been able to determine the molecular structure of a plant photolyase protein that is surprisingly similar to two cryptochrome proteins that control the "master clock" in humans and other mammals.

Deficiency in vitamin D may exacerbate autoimmune disease

Deficiency in vitamin D has been widely regarded as contributing to autoimmune disease, but a review appearing in Autoimmunity Reviews explains that low levels of vitamin D in patients with autoimmune disease may be a result rather than a cause of disease and that supplementing with vitamin D may actually exacerbate autoimmune disease.

Research could lead to new non-antibiotic drugs to counter hospital infections

Lack of an adequate amount of the mineral phosphate can turn a common bacterium into a killer, according to research to be published in the April 14, 2009, issue of the Proceedings of the National Academies of Science.

Immune cells in skin fight off infection better than the rest

Scientists at the University of Melbourne have discovered the local action of immune cells in the skin, which could improve treatment of viral skin infections.

Cigarette smoke changes the immune response to bacteria - culprit behind COPD exacerbations

Smoking cigarettes is not only the principle cause of chronic obstructive pulmonary disease (COPD), but it may change the body's immune responses to bacteria that commonly cause exacerbations of the disease, according to new research in a mouse model.
