A new study found that sexual function in adult living donors was lower at the evaluation phase and at three months following liver transplantation. Results published in Liver Transplantation, a journal of the American Association for the Study of Liver Diseases and the International Liver Transplantation Society, suggest that donor education prior to surgery may improve recovery and ease concerns about sexual function following the transplant. Living liver donors provide a healthy portion of their liver to an individual with end-stage liver disease. These donors make ...

COLUMBUS, Ohio - Researchers have identified two seemingly unrelated but strong predictors of obesity: having low self-esteem related to one's weight and keeping food visibly available around the house, outside the kitchen. The Ohio State University study focused primarily on determining whether the home environment - architectural features and food storage and availability - was associated with obesity, but also measured a number of psychological factors. While architectural features had no relationship to obesity status, several food-related findings did. People in ...

In reconstructive and esthetic medicine, a technique called cell-assisted lipotransfer, i.e., the grafting of the patient's own adipose tissue to another site in the body after mixing with autologous stem cells, is being increasingly used and aggressively promoted. This technique has not been shown to yield better outcomes than conventional lipotransfer without cell enrichment, as discussed by Soraya Grabin and coauthors in a current article in Deutsches Ärzteblatt International (Dtsch Arztebl Int 2015; 112: 255-61). The vitally important matter of safety--in particular, ...

San Francisco, CA, April 28, 2015 - Many eye disorders in young children are asymptomatic and may remain undetected without testing. Since effective treatments are available for many of those conditions, early identification and intervention are critical to prevent potentially permanent vision problems. A new report published in the Journal of the American Association for Pediatric Ophthalmology and Strabismus (AAPOS) describes the effectiveness of a new computer-based vision-screening test, the Jaeb Visual Acuity Screener (JVAS), which is suitable for use in schools and ...

Amsterdam, April 28, 2015 - The demise of Neanderthals may have nothing to do with innovative hunting weapons carried by humans from west Asia, according to a new study published in the Journal of Human Evolution. The researchers, from Nagoya University and The University of Tokyo, Japan, say their findings mean that we may need to rethink the reasons humans survived Neanderthals - and that we may not have behaved as differently as we thought. The researchers looked at innovative stone weapons used by humans about 42,000-34,000 years ago. Traditionally, anthropologists ...

EVERGLADES NATIONAL PARK, Fla.-- The largest and longest Burmese Python tracking study of its kind -- here or in its native range -- is providing researchers and resource managers new information that may help target control efforts of this invasive snake, according to a new study led by the U.S. Geological Survey. Among the findings, scientists have identified the size of a Burmese python's home range and discovered they share some "common areas" that multiple snakes use. "These high-use areas may be optimal locations for control efforts and further studies on the ...

People starting to plan for retirement or other big goals should pull out a calculator and multiply the years ahead by 365. Measuring time in days instead of months, or months instead of years, can make future events seem closer and thus more urgent, according to new research published in Psychological Science, a journal of the Association for Psychological Science. When units of time were manipulated to bring important events closer to the forefront psychologically, people reported that they should start to plan and save significantly earlier, even when future events ...

When a mirror reflects light, it experiences a slight push. This radiation pressure can be increased considerably with the help of a small superconducting island. This was revealed by the joint research done in the Aalto University and the Universities of Jyväskylä and Oulu. The finding paves a way for the studies of mechanical oscillations at the level of a single photon, the quantum of light. The results of the research were published in Nature Communications in April. In our everyday lives, the effects of the radiation pressure of light can be neglected. ...

Physicists have shown how heat can be exploited for controlling magnetic properties of matter. The finding helps in the development of more efficient mass memories. The result was published yesterday in Physical Review Letters. The international research group behind the breakthrough included Finnish researchers from the University of Jyväskylä and Aalto University. The ability to control the huge amount of information within the Internet is largely based on the ability to use the magnetic properties of electrons for reading memory devices. The phenomenon is ...
