Does moderate wine consumption improve lung function?

2012-03-12
(Press-News.org) A research team from the Netherlands assessed the impact of wine and resveratrol (a natural polyphenol found in high quantities in red wine) on lung function. It also looked at genetic factors and mechanisms by which resveratrol might be absorbed by the body and its possible effect on longevity of life. The authors report that pure resveratrol intake was associated with higher lung volumes and that white wine intake (but not red wine intake) and was associated with lower risk of airway obstruction. They report that the genetic factors studied did not relate to the associations found.

While several previous studies (as does this one) have reported that wine intake improves lung function, Forum reviewers were concerned about several aspects of the paper, and especially with the conclusions of the authors that resveratrol was the key factor in improved lung function. A reviewer stated: "Resveratrol may well be just the bystander of something else present in wine." The beneficial effects on lung function are probably related to many compounds present in wine, and not just resveratrol'.

Based on a number of scientific studies, moderate wine intake appears to have a favorable effect on lung function. The doses of resveratrol seen in these epidemiologic studies are at levels that could be expected from moderate wine consumption, unlike the huge doses of resveratrol, which we doubt are capable of being metabolized, being evaluated as a potential life-extending drug in pharmaceutical studies.

Saving power, saving money

2012-03-12
In today's computer processors, much of the power put into running the processor is being wasted. A research team at Case Western Reserve University came up with a novel idea called fine-grained power gating, which saves power and money in a couple of ways: less energy would be used, and less heat produced. "Using less power produces less heat. Less heat means less cooling is needed," said Swarup Bhunia, professor of electrical engineering and computer science and an author of the research. "That can avoid the need for a big fan to cool off the processor, which saves ...

Mom's voice may improve the health of premature babies

2012-03-12
Boston, MA – When babies are born prematurely, they are thrust into a hospital environment that while highly successful at saving their lives, is not exactly the same as the mother's womb where ideal development occurs. The Neonatal Intensive Care Unit (NICU) is equipped with highly skilled care givers and incubators that regulate temperature and humidity, but Amir Lahav, ScD, PhD, director of the Neonatal Research Lab at Brigham and Women's Hospital (BWH) thought that something was missing - simulation of the maternal sounds that a baby would hear in the womb. Now, new ...

Magnetic moon

2012-03-12
In the nearly five decades since the first lunar surveys were conducted as part of NASA's Apollo program, scientists have advanced a number of increasingly complex theories to explain the vast swaths of highly magnetic material that had been found in the some parts of the Moon's crust. But now a team of researchers from Harvard, MIT and the Institut de Physique du Globe de Paris, have proposed a surprisingly simple explanation for the unusual findings – the magnetic anomalies are remnants of a massive asteroid collision. As described in a paper published March 9 in Science, ...

Metamaterials may advance with new femtosecond laser technique

Metamaterials may advance with new femtosecond laser technique
2012-03-12
Cambridge, Mass. - March 8, 2012 - Researchers in applied physics have cleared an important hurdle in the development of advanced materials, called metamaterials, that bend light in unusual ways. Working at a scale applicable to infrared light, the Harvard team has used extremely short and powerful laser pulses to create three-dimensional patterns of tiny silver dots within a material. Those suspended metal dots are essential for building futuristic devices like invisibility cloaks. The new fabrication process, described in the journal Applied Physics Letters, advances ...

Cultural 'tightness' holds back female leadership -- but not always, says study

2012-03-12
Toronto – Countries that more strictly uphold their cultural norms are less likely to promote women as leaders – unless those norms support equal opportunity for both sexes, shows a new paper from the University of Toronto's Rotman School of Management. "Cultural tightness can prevent the emergence of women leaders because tighter cultures may make a society's people more resistant to changing the traditionally-held practice that placed men in leadership roles," says Prof. Soo Min Toh, who is cross-appointed to the Rotman School and the University of Toronto Mississauga, ...

Maternal obesity may influence brain development of premature infants

2012-03-12
Winston-Salem, N.C. – March 8, 2012 -- Maternal obesity may contribute to cognitive impairment in extremely premature babies, according to a new study by researchers at Wake Forest Baptist Medical Center. "Although in the past decade medical advances have improved the survival rate of babies born at less than seven months, they are still at very high risk for mental developmental delays compared with full-term infants," said Jennifer Helderman, M.D., assistant professor of pediatrics at Wake Forest Baptist and lead author of the study. "This study shows that obesity doesn't ...

Children's National team gains understanding of white matter in infants receiving heart surgery

2012-03-12
Washington, DC – A collaborative team of researchers at Children's National Medical Center are making progress in understanding how to protect infants needing cardiac surgery from white matter injury, which impacts the nervous system. The synergistic team from the Children's National Heart Institute and Center for Neuroscience Research at Children's National Medical Center was led by Nobuyuki Ishibashi, MD, Joseph Scafidi, DO, Richard Jonas, MD, and Vittorio Gallo, PhD. The study, published online in the January edition of Circulation, identifies the stages of white matter ...

Reports on impact of poverty and social class on myocardial infarction outcomes

2012-03-12
Philadelphia, PA, March 6, 2012 – The Canadian Journal of Cardiology has published a paper on the effect of socioeconomic factors on myocardial infarction outcomes. This study describes an analysis of the effect of socioeconomic class on outcomes after a first myocardial infarction ("heart attack"). The study analyzed detailed databases in Quebec and found that socioeconomic deprivation did not negatively affect access to the most advanced high-level health care – clearly a success for the Canadian public healthcare system. Nevertheless, mortality rates were slightly ...

Origami-inspired paper sensor could test for malaria and HIV for less than 10 cents, report chemists

Origami-inspired paper sensor could test for malaria and HIV for less than 10 cents, report chemists
2012-03-12
AUSTIN, Texas — Inspired by the paper-folding art of origami, chemists at The University of Texas at Austin have developed a 3-D paper sensor that may be able to test for diseases such as malaria and HIV for less than 10 cents a pop. Such low-cost, "point-of-care" sensors could be incredibly useful in the developing world, where the resources often don't exist to pay for lab-based tests, and where, even if the money is available, the infrastructure often doesn't exist to transport biological samples to the lab. "This is about medicine for everybody," says Richard Crooks, ...
