New research sheds light on pluripotency

New research at the Hebrew University of Jerusalem sheds light on pluripotency-the ability of embryonic stem cells to renew themselves indefinitely and to differentiate into all types of mature cells.

Pioneering technique that uses thermal imaging can help fight obesity

Scientists at The University of Nottingham believe they've found a way of fighting obesity — with a pioneering technique which uses thermal imaging. This heat-seeking technology is being used to trace our reserves of brown fat — the body's 'good fat' — which plays a key role in how quickly our body can burn calories as energy.

Diabetes linked to onset of Alzheimer's disease

Researchers from the University of Medicine and Dentistry of New Jersey (UMDNJ), collaborating with scientists from Northwestern University in Illinois, have provided direct experimental evidence that diabetes is linked to the onset of Alzheimer's disease.

Researchers verify role of alpha-synuclein aggregates in vivo

Using a two-photon microscope capable of peering deep within living tissue, researchers at the University of California, San Diego School of Medicine have found new evidence that alpha-synuclein protein build-up inside neurons causes them to not only become "leaky," but also to misfire due to calcium fluxes.

Inhibiting STAT3 might unleash an effective anti-lymphoma immune response

Researchers at Moffitt Cancer Center and colleagues have demonstrated that the inhibition of signal transducer and activator of transcription 3 (STAT3) in mouse models of mantle cell lymphoma (MCL), an aggressive and incurable subtype of B-cell non-Hodgkin lymphoma that becomes resistant to treatment, can harness the immune system to eradicate residual malignant cells responsible for disease relapse.

Metabolic syndrome may reduce cerebral blood flow

Metabolic syndrome, a term used to describe a combination of risk factors that often lead to heart disease and type 2 diabetes, seems to be linked to lower blood flow to the brain, according to research by the University of Wisconsin School of Medicine and Public Health.

High ceramide levels may increase a person's risk of AD

Higher levels of a certain fat in the blood called ceramides may increase a person's risk of developing Alzheimer's disease, according to a study published in the July 18, 2012, online issue of Neurology, the medical journal of the American Academy of Neurology.

Abscisic acid has anti-inflammatory effects in the lungs and gut

Building on previous work with the botanical abscisic acida, researchers in the Nutritional Immunology and Molecular Medicine Laboratory (NIMML) have discovered that abscisic acid has anti-inflammatory effects in the lungs as well as in the gut.

Researchers identify new behavior for the human macrophage

Researchers at the Institute of Human Virology of the University of Maryland School of Medicine have identified a new behavior for the human macrophage that provides new explanations for several features of HIV biology, including how the virus persists within the body indefinitely, how quiescently infected CD4+ T-cells arise, and how the infection leads to depletion of CD4+ T-cells.

ADHD drugs do not appear to have long-term effects on the brain

Drugs used to treat Attention Deficit Hyperactivity Disorder (ADHD) do not appear to have long-term effects on the brain, according to new animal research from Wake Forest Baptist Medical Center.

Study focuses on interaction between two key proteins involved in apoptosis

A promising method for promoting programmed cell death (apoptosis) developed by researchers at the Hebrew University of Jerusalem and the Weizmann Institute of Science paves the way for a possible novel therapy to target cancer cells.

CSIRO to produce antibodies for development of new vaccines against rotavirus

CSIRO has been contracted by PATH (Program for Appropriate Technology in Health) to produce antibodies on a large scale that will aid the development of new, safe, affordable and effective vaccines against rotavirus, a major cause of severe and fatal diarrhoea in young children worldwide.

Research explains why exercise is beneficial for heart function in type 2 diabetes

A detailed study of heart muscle function in mice has uncovered evidence to explain why exercise is beneficial for heart function in type 2 diabetes. The research team, led by scientists at the Johns Hopkins University School of Medicine, found that greater amounts of fatty acids used by the heart during stressful conditions like exercise can counteract the detrimental effects of excess glucose and improve the diabetic heart's pumping ability in several ways.

Nanofiber scaffolds regenerate protein components in cartilage repair

Johns Hopkins tissue engineers have used tiny, artificial fiber scaffolds thousands of times smaller than a human hair to help coax stem cells into developing into cartilage, the shock-absorbing lining of elbows and knees that often wears thin from injury or age. Reporting online June 4 in the Proceedings of the National Academy of Sciences, investigators produce an important component of cartilage in both laboratory and animal models.
