Low-carb diet burns more excess liver fat than low-cal diet

People on low-carbohydrate diets are more dependent on the oxidation of fat in the liver for energy than those on a low-calorie diet, researchers at UT Southwestern Medical Center have found in a small clinical study.

First '3D movie' of tumour protein gives new drug hope

First '3D movie' of tumour protein gives new drug hope CANCER RESEARCH UK scientists have created the first complete model of a molecule which captains a key cell signalling network to prevent cancer - and exposed the secret of how a highly selective drug can intervene to control its activity, according to a study published in PLoS Biology.

Discovery could lead to novel arrhythmia treatments

Abnormal heart rhythms - arrhythmias - are killers. They strike without warning, causing sudden cardiac death, which accounts for about 10 percent of all deaths in the United States.

New findings on schizophrenia

Schizophrenia may blur the boundary between internal and external realities by overactivating a brain system that is involved in self-reflection, and thus causing an exaggerated focus on self, a new MIT and Harvard brain imaging study has found.

New technique images whole cells in liquid with a scanning transmission electron microscope

Scientists have always wanted to take a closer look at biological systems and materials.

New understanding on how aging causes broken bones to heal slowly

Researchers have unraveled crucial details of how aging causes broken bones to heal slowly, or not at all, according to study results published today in the Journal of Bone and Mineral Research.

Lack of grey matter linked to schizophrenia and bipolar disorder

A research study led by scientists from the Gregorio Marañón University Hospital in Madrid and the Network of Centres for Biomedical Research in Mental Health Networks (CIBERSAM) shows that adolescents experiencing a first outbreak of psychosis have lower levels of grey matter in their brains than healthy teenagers. Strangely, this change was seen in patients suffering from various psychoses, including bipolar illness and schizophrenia.

Artificial antibody delivers nanoparticles to tumors

Antibodies that target epidermal growth factor receptor (EGFR) have proven themselves as potent anticancer drugs. Now, a team of investigators led by Shuming Nie, Ph.D., and Lily Yang, Ph.D., both at the Emory University School of Medicine and members of the Emory-Georgia Tech Nanotechnology Center for Personalized and Predictive Oncology, is aiming to capitalize on this targeting ability, using a modified anti-EGFR antibody to delivery nanoparticles into tumor cells.

Toxin-nanoparticle combo inhibits brain cancer invasion while imaging tumors

Working with a nanoparticle designed to target and image glioblastoma, a form of brain cancer, investigators at the University of Washington in Seattle have found that these same nanoparticles inhibit tumor cell invasion, one of the key events that leads to the metastatic spread of cancer. The investigators have also determined how the nanoparticles exert this potentially beneficial effect.

Biodegradable nanoprobe images new blood vessel growth

Angiogenesis, the growth of new blood vessels, plays a critical role in several chronic human diseases, including metastatic cancer. In fact, several new anticancer therapies are designed to starve tumors by shutting down angiogenesis, but the lack of a good assay for quantifying angiogenesis in the body has hampered the development of effective antiangiogenesis therapies.
