Bacteria are key contributors to the cause of IBS, study confirms

An overgrowth of bacteria in the gut has been definitively linked to Irritable Bowel Syndrome in the results of a new Cedars-Sinai study which used cultures from the small intestine. This is the first study to use this "gold standard" method of connecting bacteria to the cause of the disease that affects an estimated 30 million people in the United States.

Immune system involved in removing Alzheimer's-causing substance in the brain

Recent work in mice suggested that the immune system is involved in removing beta-amyloid, the main Alzheimer's-causing substance in the brain. Researchers have now shown for the first time that this may apply in humans.

Brain can rewire even at an advanced age

"This study overturns decades-old beliefs that most of the brain is hard-wired before a critical period that ends when one is a young adult," said MPFI neuroscientist Marcel Oberlaender, PhD, first author on the paper.

BBSRC allocates £250M for strategic investment programmes

Minister for Universities and Science, David Willetts, will today announce substantial funding that will ensure the UK's bioscience research base remains globally competitive and at the forefront of meeting the grand challenges faced by society in the coming decades. The announcement will be made by the Minister during a visit to the Babraham Research Campus, near Cambridge, and highlighted again during a major speech at the University of East Anglia in Norwich.

Gene therapy can effectively treat ADA-deficient severe combined immunodeficiency

Severe combined immunodeficiency is defect in the immune system that results in a loss of the adaptive immune cells known as B cells and T cells. Mutations in several different genes can lead to the development of severe combined immunodeficiency, including mutation of the adenosine deaminase (ADA) gene. Traditional treatment options, such as enzyme replacement therapy, are of limited efficacy, but bone marrow transplant from a compatible donor leads to a better response.

University of Kentucky researcher receives $1.8M NIH grant to study CF

David Feola, a University of Kentucky College of Pharmacy faculty member in the Department of Pharmacy Practice and Science, received a five-year, $1.8 million grant from the National Institutes of Health (NIH) to continue his research investigating immune responses in the lungs that will potentially lead to the discovery of medical treatments for patients with cystic fibrosis and other chronic pulmonary inflammatory conditions.

Thioridazine drug successfully kills human cancer stem cells

A team of scientists at McMaster University has discovered a drug, thioridazine, successfully kills cancer stem cells in the human while avoiding the toxic side-effects of conventional cancer treatments.

New diagnostic approach for Lyme disease

George Mason University researchers can find out if a tick bite means Lyme disease well before the bite victim begins to show symptoms.

Researchers uncover series of biological events that implicate stem cells' surroundings

Stem cells are essential building blocks for all organisms, from plants to humans. They can divide and renew themselves throughout life, differentiating into the specialized tissues needed during development, as well as cells necessary to repair adult tissue.

Study reveals why people develop life-threatening drug allergies

A research team led by the University of Melbourne and Monash University, Australia, has discovered why people can develop life-threatening allergies after receiving treatment for conditions such as epilepsy and AIDS.

RUB researchers gain new insights into mechanisms of cardiovascular disease

Malformed desmin proteins aggregate with intact proteins of the same kind, thereby triggering skeletal and cardiac muscle diseases, the desminopathies. This was discovered by researchers from the RUB Heart and Diabetes Center NRW in Bad Oeynhausen led by PD Dr. Hendrik Milting in an interdisciplinary research project with colleagues from the universities in Karlsruhe, Würzburg and Bielefeld. They report in the Journal of Biological Chemistry.

UCSF scientists aim to use embryonic stem cells for treatment of neuropathic pain

Chronic pain, by definition, is difficult to manage, but a new study by UCSF scientists shows how a cell therapy might one day be used not only to quell some common types of persistent and difficult-to-treat pain, but also to cure the conditions that give rise to them.

New compound can enhance apoptosis in cancer cells

The BCL-2 protein family plays a large role in determining whether cancer cells survive in response to therapy or undergo a form of cell death known as apoptosis.

Changes in sensory experience can cause massive rewiring of the brain

Despite a long-held scientific belief that much of the wiring of the brain is fixed by the time of adolescence, a new study shows that changes in sensory experience can cause massive rewiring of the brain, even as one ages. In addition, the study found that this rewiring involves fibers that supply the primary input to the cerebral cortex, the part of the brain that is responsible for sensory perception, motor control and cognition.

PERK protein necessary to maintain behavioral flexibility

Researchers have identified a protein necessary to maintain behavioral flexibility, which allows us to modify our behaviors to adjust to circumstances that are similar, but not identical, to previous experiences. Their findings, which appear in the journal Cell Reports, may offer new insights into addressing autism and schizophrenia—afflictions marked by impaired behavioral flexibility.

Oestrogen promotes presence of 'mucoid' form of P. aeruginosa in women with CF

Researchers from the Respiratory Research Division of the Department of Medicine, Royal College of Surgeons in Ireland (RCSI) have published a study which represents a major breakthrough in understanding why females with cystic fibrosis do worse than males.
