Personal reflection triggers increased brain activity during depressive episode

Research by the Universities of Liverpool and Manchester has found that people experiencing depressive episodes display increased brain activity when they think about themselves.

Using functional magnetic resonance imaging (fMRI) brain imaging technologies, scientists found that people experiencing a depressive episode process information about themselves in the brain differently to people who are not depressed.

Researchers scanned the brains of people in major depressive episodes and those that weren’t whilst they chose positive, negative and neutral adjectives to describe either themselves or the British Queen – a figure significantly removed from their daily lives but one that all participants were familiar with.

An experimental cancer drug that has shown promise in the treatment of melanoma has also shown early potential as an effective treatment for patients with non-small cell lung cancer, the leading cause of cancer death among men and women worldwide.

Dr. Edward Garon, director of thoracic oncology at UCLA’s Jonsson Comprehensive Cancer Center, presented the preliminary results of a Phase 1B study of the new drug, called MK-3475, on Oct. 29 at the World Conference on Lung Cancer in Sydney, Australia. (more…)

Research provides new insights into bone biology

Bone marrow, the spongy tissue inside long bones, produces new blood cells and helps the lymphatic system work properly. But it may also turn out to be a progressively hostile microenvironment that induces vascular dysfunction and ossification, or hardening, of blood vessels.

Rhonda Prisby, who is using a rat model to study bone vascular physiology and morphology, was recently surprised when she used light microscopy to look at bone marrow vessels. (more…)

Brain may play key role in blood sugar metabolism and diabetes development

A growing body of evidence suggests that the brain plays a key role in glucose regulation and the development of type 2 diabetes, researchers write in the Nov. 7 ssue of the journal Nature. If the hypothesis is correct, it may open the door to entirely new ways to prevent and treat this disease, which is projected to affect one in three adults in the United States by 2050.

In the paper, lead author Dr. Michael W. Schwartz, UW professor of medicine and director of the Diabetes and Obesity Center of Excellence, and his colleagues from the universities of Cincinnati, Michigan, and Munich, note that the brain was originally thought to play an important role in maintaining normal glucose metabolism With the discovery of insulin in the 1920s, the focus of research and diabetes care shifted to almost exclusively to insulin. Today, almost all treatments for diabetes seek to either increase insulin levels or increase the body’s sensitivity to insulin. (more…)

UCLA researchers build a multisensory virtual world

To survive, animals must explore their world to find the necessities of life. It’s a complex task, requiring them to form them a mental map of their environment to navigate the safest and fastest routes to food and water. They also learn to anticipate when and where certain important events, such as finding a meal, will occur.
