Brain study may lead to new forms of treatment for Alzheimer's disease

A study from EPFL's (Ecole Polytechnique F-d-rale de Lausanne) Laboratory of Neuroenergetics and Cellular Dynamics in Lausanne Switzerland, published today in the Journal of Neuroscience, may lead to new forms of treatment following a better understanding of how Amyloid-Beta found in cerebral plaques, typically present in the brain of Alzheimer's patients, may lead to neurodegeneration.

Severe inflammatory diseases: Blocking "death messenger" might be a promising treatment

The signaling molecule CD95L, known as "death messenger," causes an inflammatory process in injured tissue after spinal cord injuries and prevents its healing. This discovery was published by scientists of the German Cancer Research Center. In mice, the researchers found out that if they switch off CD95L, the injured spinal cord heals and the animals regain better ability to move. Therefore, substances which block the death messenger might offer a new approach in the treatment of severe inflammatory diseases.

Boosting immune response to vaccinations: Role of aluminium adjuvants

An imminent publication in Trends in Immunology by a leading researcher in the bioinorganic chemistry of aluminium, Dr Christopher Exley, Reader in Bioinorganic Chemistry at The Birchall Centre, Keele University in Staffordshire, has now gone some way to giving the fullest possible explanation of how aluminium adjuvants work in boosting the immune response to vaccination.

Study: Bacteria, fungi and other microbes live in our gut are essential contributors to good health

The thousands of bacteria, fungi and other microbes that live in our gut are essential contributors to our good health. They break down toxins, manufacture some vitamins and essential amino acids, and form a barrier against invaders. A study published today in Nature shows that, at 3.3 million, microbial genes in our gut outnumber previous estimates for the whole of the human body.

Cryoablation kills breast tumors in mice

Freezing a cancer kills it in its place, and also appears to generate an immune response that helps stop the cancer's spread, leading to improved survival rates over surgery, according to a new study in mice from researchers at the University of Michigan Comprehensive Cancer Center.

Cornell researchers find new protein that may help control mosquitoes from spreading diseases

Cornell researchers have found a protein that may lead to a new way to control mosquitoes that spread dengue fever, yellow fever and other diseases when they feed on humans: Prevent them from urinating as they feed on blood.

Gene therapy for LCA clears another hurdle: Study

Gene therapy for a severe inherited blindness, which produced dramatic improvements last year in 12 children and young adults who received the treatment in a clinical trial, has cleared another hurdle. The same research team that conducted the human trial now reports that a study in animals has shown that a second injection of genes into the opposite, previously untreated eye is safe and effective, with no signs of interference from unwanted immune reactions following the earlier injection.

Corning commercializes new Synthemax synthetic surface for supporting growth and differentiation of stem cells

Corning Incorporated today introduced the Corning® Synthemax™ surface, a novel synthetic surface that supports the growth and differentiation of stem cells. The surface is being commercialized as a result of Corning’s ongoing collaboration with Geron Corporation. This development enables researchers to take the next step toward scalable and cost-effective manufacturing of stem cells for potential therapies in the treatment of degenerative diseases.

Increasing antibiotic resistance among soil microbes

A team of scientists in the United Kingdom and the Netherlands are reporting disturbing evidence that soil microbes have become progressively more resistant to antibiotics over the last 60 years. Surprisingly, this trend continues despite apparent more stringent rules on use of antibiotics in medicine and agriculture, and improved sewage treatment technology that broadly improves water quality in surrounding environments. Their report appears in ACS' bi-weekly journal Environmental Science and Technology.

Scientists identify two proteins that serve as biomarkers for tracking the spread of colon cancer

Scientists in China are reporting discovery of two proteins present in the blood of people with colon cancer that may serve as the potential biomarkers for accurately predicting whether the disease will spread. Their study is in ACS' Journal of Proteome Research, a monthly publication.

Lemelson-MIT Collegiate Student Prizes awarded to inventive students nationwide

A scientific "Renaissance man" whose work spans the fields of mathematics, linguistics, biotechnology and polymer physics, Erez Lieberman-Aiden, graduate student at the Harvard-MIT Division of Health Sciences and Technology, has been named the winner of the prestigious $30,000 Lemelson-MIT Student Prize. Lieberman-Aiden, one of four 2010 $30,000 Lemelson-MIT Collegiate Student Prize winners announced today, was selected for the breadth and depth of his innovations.

Researchers explore molecular origin of skin and hair to develop novel beauty products

Scientists at L'Or-al, in hot pursuit of the hidden elements of beauty, seem well on their way to disputing the old adage, "beauty is only skin deep." In fact, their work indicates that what makes hair curly or straight and skin smooth or rough, is much deeper.

Gene 'addiction' of leukaemia cells

An international team of scientists studying acute forms of Leukaemia have identified a new drug target to inhibit the genes which are vital for the growth of diseased cells. The research, reported in EMBO Molecular Medicine, reveals how leukaemia cells become 'addicted' to genes, which if targeted could prevent diseased cells from developing.

Blood glucose-lowering hormone FGF21 also activates brown adipose tissue metabolism

The blood glucose-lowering hormone FGF21 is also an activator of brown adipose tissue metabolism, according to the study featured on the cover of Cell Metabolism and directed by the lecturer Francesc Villarroya of the UB's Department of Biochemistry and Molecular Biology (Faculty of Biology), the Institute of Biomedicine, and the Biomedical Research Networking Centre in Physiopathology of Obesity and Nutrition.

Mood, behavioral problems after stressful interpersonal events: LPFC function may be a risk-factor

Think back to your last fight with someone you love. How did you feel afterwards? How did you behave? Conflict with a loved one often leaves a person feeling terrible and then behaving badly. So much so that these scenarios have become soap opera clich-s. After an argument, one partner may brood, slam the door, and then drive to a local bar to drown their sorrows in alcohol. These dramas rarely have happy endings. Given these stereotypes, how do people control their emotional reactions and prevent emotional storms and their attendant use of intoxicating substances?

Vaccine researchers at HZI find c-di-IMP molecule, more effective than known adjuvants

The adjuvants present in vaccines have a bad reputation. For most people, they are only unnecessary compounds within a medicinal product. This is a misunderstanding since adjuvants have a critical impact on the success of a vaccination. In the best case scenario, one single vaccination shot would be now sufficient for conferring life-long protection.
