Cells in Blood Vessel Found To Cling More Tightly in Regions of Rapid Flow

Clogging of pipes leading to the heart is the planet’s number one killer. Surgeons can act as medical plumbers to repair some blockages, but we don’t fully understand how this living organ deteriorates or repairs itself over time.

Researchers at the University of Washington have studied vessel walls and found the cells pull more tightly together, reducing vascular leakage, in areas of fast-flowing blood. The finding could influence how doctors design drugs to treat high cholesterol, or how cardiac surgeons plan their procedures. (more…)

2008 recommendations from federal task force had no impact

New research confirms that the controversial decision by Warren Buffett – the 81-year-old CEO of Berkshire Hathaway – to undergo a blood test screening for prostate cancer despite his age is hardly unusual. Despite recommendations in 2008 from the United States Preventive Services Task Force against testing for prostate cancer in men aged 75 years or older, almost half of men in that age group continue to get screening tests.

In 2005, before the recommendations were released, 43 percent of men age 75 and above elected to take the prostate-specific antigen (PSA) test. In August 2008, the Task Force stated it “recommends against the service,” arguing “there is moderate or high certainty the service has no net benefit or that the harms outweigh the benefits.” (more…)

Researchers at the University of Montreal’s Sainte-Justine Hospital have identified how neural cells are able to build up resistance to opioid pain drugs within hours. “A better understanding of these mechanisms will enable us to design drugs that avoid body resistance to these drugs and produce longer therapeutic responses, including longer-acting opioid analgesics”, lead author Dr. Graciela Pineyro said.

Study shows religious participation and spirituality processed in different cerebral regions

COLUMBIA, Mo. – Scientists have speculated that the human brain features a “God spot,” one distinct area of the brain responsible for spirituality. Now, University of Missouri researchers have completed research that indicates spirituality is a complex phenomenon, and multiple areas of the brain are responsible for the many aspects of spiritual experiences.

COLUMBIA, Mo. – Since 1992, the government’s Back-to-Sleep Campaign has encouraged parents to place infants on their backs to sleep. Still, more than 4,500 infants die unexpectedly during sleep each year in the United States. Now, a University of Missouri injury prevention researcher says that safe, separate sleep environments for infants are critical to preventing sudden unexpected infant deaths (SUIDs).

“Many of these SUIDs are due to unsafe sleep environments, and these deaths are totally preventable,” said Patricia Schnitzer, an associate professor in the MU Sinclair School of Nursing. “The safest place for infants to sleep is on their backs in their own cribs without soft bedding.” (more…)
