Pigs’ hearts transplanted into baboon hosts remain viable more than a year

Pigs’ hearts transplanted into baboon hosts remain viable more than a year

Investigators from the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health (NIH) have successfully transplanted hearts from genetically engineered piglets into baboons’ abdomens and had the hearts survive for more than one year, twice as long as previously reported. This was achieved by using genetically engineered porcine donors and a more focused immunosuppression regimen in the baboon recipients, according to a study published in The Journal of Thoracic and Cardiovascular Surgery , an official publication of the American Association for Thoracic Surgery. Cardiac transplantation is the treatment of choice for end stage heart failure. Continue reading

Do gut bacteria rule our minds?  In an ecosystem within us, microbes evolved to sway food choices

Do gut bacteria rule our minds? In an ecosystem within us, microbes evolved to sway food choices

It sounds like science fiction, but it seems that bacteria within us — which outnumber our own cells about 100-fold — may very well be affecting both our cravings and moods to get us to eat what they want, and often are driving us toward obesity. In an article published this week in the journal BioEssays , researchers from UC San Francisco, Arizona State University and University of New Mexico concluded from a review of the recent scientific literature that microbes influence human eating behavior and dietary choices to favor consumption of the particular nutrients they grow best on, rather than simply passively living off whatever nutrients we choose to send their way Continue reading

Study details shortage of replication in education research

Study details shortage of replication in education research

Although replicating important findings is essential for helping education research improve its usefulness to policymakers and practitioners, less than one percent of the articles published in the top education research journals are replication studies, according to new research published today in Educational Researcher ( ER ), a peer-reviewed journal of the American Educational Research Association. “Facts Are More Important Than Novelty: Replication in the Education Sciences,” by Matthew C.

Hospitals could face penalties for missing electronic health record deadline

Hospitals could face penalties for missing electronic health record deadline

Many of the nation’s hospitals struggled to meet a federally mandated electronic health records deadline, and as a result could collectively face millions of dollars in reduced Medicare payments this year, a University of Michigan study shows. More than half of U.S. hospitals were on the hook to meet a new set of “meaningful use” of electronic health records criteria — known as the stage 2 criteria — by the end of the fiscal year that ended in July Continue reading

Pictures in five seconds: Digital x-ray imaging

Wanting to replace the medical equipment for taking X-rays, the Mexican Society of Radiology (CMR) created a system of digital x-ray imaging, which replaces the traditional plaque by a solid detector, which delivers results in five seconds. Continue reading

Brain tumors fly under body’s radar like stealth jets, new research suggests

Brain tumors fly under the radar of the body’s defense forces by coating their cells with extra amounts of a specific protein, new research shows. Like a stealth fighter jet, the coating means the cells evade detection by the early-warning immune system that should detect and kill them. Continue reading
