Study extends scientific understanding of how pheromones activate the vomeronasal organ

The vomeronasal organ (VNO) is one of evolution's most direct enforcers. From its niche within the nose in most land-based vertebrates, it detects pheromones and triggers corresponding basic-instinct behaviors, from compulsive mating to male-on-male death matches. A new study from the Stowers Institute for Medical Research, published online in Nature Neuroscience on July 29, 2012, extends the scientific understanding of how pheromones activate the VNO, and has implications for sensory transduction experiments in other fields.

Combined approach reduces SSIs by 33% in patients after colorectal procedures

A surgical patient safety program that combines three components-accurate outcome measurement, support of hospital leadership, and engaged frontline providers-reduces surgical site infections (SSIs) by 33 percent in patients who undergo colorectal procedures, according to a new study published in the August issue of the Journal of the American College of Surgeons.

Lack of physical activity and life expectancy: an interview with Dr I-Min Lee

With the approach of the Olympic Games, a group of researchers throughout the world thought that it would be a good time to draw the attention of the world to the health dangers of being physically inactive.

Researchers describe new human tissue dendritic cell with cross-presenting function

Researchers in Newcastle and Singapore have identified a new type of white blood cell which activates a killing immune response to an external source - providing a new potential target for vaccines for conditions such as cancer or Hepatitis B.

Patients with plantar fasciitis experience less pain and improved QOL after standard radiation therapy

Patients with plantar fasciitis (painful bone heel spur) experience significantly less pain and improved quality of life following a standard dose of external beam radiation therapy, a common cancer treatment similar to receiving an X-ray, according to a randomized, cooperative group study that was published online July 25, 2012, in the International Journal of Radiation, Oncology, Biology, Physics (Red Journal), the official scientific journal of the American Society for Radiation Oncology (ASTRO).

Study examines how heterosexual men with HIV seek health care and support services

Heterosexual men make up a small but growing number of people infected with HIV in Canada. Yet a new study has found that many of them feel existing HIV-related programs and services don't meet their needs and are geared primarily or exclusively toward gay men and heterosexual women who are living with the virus.

New assay method finds evidence of clonal evolution in chronic lymphocytic leukemia

Using a new assay method to study tumor cells, researchers at the University of California, San Diego School of Medicine and UC San Diego Moores Cancer Center have found evidence of clonal evolution in chronic lymphocytic leukemia (CLL).

New compound effective at blocking damage to the retina in diabetic retinopathy

Researchers at the University of Michigan Kellogg Eye Center have identified a compound that could interrupt the chain of events that cause damage to the retina in diabetic retinopathy. The finding is significant because it could lead to a novel therapy that targets two mechanisms at the root of the disease: inflammation and the weakening of the blood barrier that protects the retina.

Fruit flies help pinpoint genetic changes that spell cancer

By studying fruit flies, scientists at A*STAR's Institute of Molecular and Cell Biology (IMCB) have successfully devised a fast and cost-saving way to uncover genetic changes that have a higher potential to cause cancer. With this new approach, researchers will now be able to rapidly distinguish the range of genetic changes that are causally linked to cancer (i.e. "driver" mutations) versus those with limited impact on cancer progression.

Health systems must prepare for aging population living with HIV

"Many health systems are not ready to cope with the relatively new phenomenon" of people living with HIV (PLHIV) growing older, PlusNews reports. "Data on aging with HIV is largely restricted to the developed world and very little is known about older Africans living with virus, despite the high caseload in this region," the news service writes, adding, "A July 2012 supplement of the medical journal, AIDS, notes that an estimated three million people in sub-Saharan Africa aged 50 and older are HIV-positive -- 14 percent of all infected adults.

Early ART treatment delays AIDS-related health events in HIV-infected individuals

Further analyses of the landmark NIH-funded treatment-as-prevention study (HPTN 052) have found that providing antiretroviral treatment to HIV-infected individuals earlier, when their immune systems are healthier, delays AIDS-related health events, such as chronic herpes simplex virus and tuberculosis, as well as death. Additionally, researchers found that earlier HIV treatment is also cost-effective because it increases survival, prevents costly opportunistic infections and averts transmission of the virus to uninfected individuals.

Neurotez receives U.S. patent for Leptin to treat Alzheimer's

Neurotez, Inc. today announced the grant of U.S. Patent number 8,227,408 by the United States Patent and Trademark Office covering the company's lead product candidate, Leptin. The patent protects use of the hormone Leptin for treating a progressive cognitive disease, disorder or condition, such as Alzheimer's disease (AD), resulting from accumulation of an amyloid peptide or for improving resilience of cognitive function by modulating the accumulation of the amyloid peptide in brain.

Group yoga can boost motor function and balance in stroke survivors

Group yoga can improve motor function and balance in stroke survivors, even if they don't begin yoga until six months or more after the stroke, according to "Post-Stroke Balance Improves With Yoga: A Pilot Study," published online July 26 in the journal Stroke.

Insight into neural basis of human consciousness

Which areas of the brain help us to perceive our world in a self-reflective manner is difficult to measure. During wakefulness, we are always conscious of ourselves. In sleep, however, we are not. But there are people, known as lucid dreamers, who can become aware of dreaming during sleep. Studies employing magnetic resonance tomography (MRT) have now been able to demonstrate that a specific cortical network consisting of the right dorsolateral prefrontal cortex, the frontopolar regions and the precuneus is activated when this lucid consciousness is attained.
