Scientists find lack of experimental evidence detailing biologic roles of leptin in metabolism

Discovered more than two decades ago, the hormone leptin has been widely hailed as the key regulator of leanness. Yet, the pivotal experiments that probe the function of this protein and unravel the precise mechanism of its action as a guardian against obesity are largely missing.

Insulin in the brain may help regulate eating behavior and facilitate weight loss, study shows

Eating behavior and the subjective feeling of hunger are regulated by a variety of hormones. Here a key role is played by the hormone insulin because it is not only active in the body, but also in the brain.

Consuming more fish could reduce symptoms of arthritis, study finds

A new study conducted by Brigham and Women's Hospital and Harvard Medical School shows that increased intake of fish reduces the symptoms of rheumatoid arthritis. The study has found reduced levels of arthritis in people who consumed fish twice or more than twice a week, compared with people who never consumed fish or consumed it less than once in a month.

Researchers identify new way to effectively kill cancer stem cells using existing drugs

A team of researchers at McMaster University has identified a unique feature of cancer stem cells that can be exploited to kill the deadly cells thought to be the reason that cancer comes back after therapy.

New biomarker assay improves detection, assessment of neuroblastoma

Investigators at The Saban Research Institute of Children's Hospital Los Angeles have developed and tested a new biomarker assay for quantifying disease and detecting the presence of neuroblastoma even when standard evaluations yield negative results for the disease.

Study provides evidence that cortical targets could enhance motor function after spinal cord injury

Monica A. Perez, P.T., Ph.D., Associate Professor, Department of Neurological Surgery and The Miami Project, and colleagues, recently published A novel cortical target to enhance hand motor output in humans with spinal cord injury in the June issue of Brain that provides the first evidence that cortical targets could represent a novel therapeutic site for improving motor function in humans paralyzed by spinal cord injury (SCI).

Japanese scientists show how male pheromone enhances female sexual behavior in mice

A study by a group of Japanese scientists showed how a male pheromone in mice enhances sexual behaviors in females--and how it may enhance a different behavior, aggression, in males -- by identifying distinct neural circuits and neurons that generate a particular behavioral response to specific chemical signals.

Study shows how high fat diets can alter gut bacteria to combat harmful inflammation

Researchers at Case Western Reserve University School of Medicine have shown a high fat diet may lead to specific changes in gut bacteria that could fight harmful inflammation--a major discovery for patients suffering from Crohn's disease.

Moderate physical activity linked to healthy glucose metabolism in the brain

People at risk for Alzheimer's disease who do more moderate-intensity physical activity, but not light-intensity physical activity, are more likely to have healthy patterns of glucose metabolism in their brain, according to a new UW-Madison study.

Could the mTOR pathway be used to protect against cancer?

The mTOR pathway is probably the main pathway in humans and other animals that drives growth. That is, the accumulation of mass and adding mass to make an organism bigger by both making more cells, and making cells grow and become bigger.

Lone star tick likely to be triggering red meat allergies

Experts believe that the lone star tick is responsible for the meat allergies people are developing in South-eastern states including North Carolina, Tennessee and Virginia. The ticks are spreading up the Eastern seaboard to new locations, where they are triggering allergies after just a single mouthful of meat is eaten.

Researchers discover unknown enzyme in pathogens responsible for African sleeping sickness

The life-threatening African trypanosomiasis, also called sleeping sickness, is caused by protozoa of the species Trypanosoma brucei. A team at the Biocentre of the Julius-Maximilians-Universität Würzburg in Bavaria, Germany, studies the pathogens and has now reported exciting news: The trypanosomes have a so far unknown enzyme which does not exist in humans and other vertebrates. This makes it a promising target for therapy.

Specific cerebral circuitry bridges chemical changes and behavioral expressions in PTSD

Specific cerebral circuitry bridges chemical changes deep in the brain and the more outward behavioral expressions associated with post-traumatic stress disorder (PTSD), which could lead to more objective biomarkers for the disorder, according to a comprehensive review of rapidly changing data published June 22 in The New England Journal of Medicine.
