Contact lenses purchased over Internet may place individuals at risk for harmful eyecare practices
Purchasing contact lenses online may save consumers time, but the process could cause more problems in the long run, according to a new study reported in the January issue of Optometry: Journal of the American Optometric Association. The research, conducted by Joshua Fogel, Ph.D., and Chaya Zidile of Brooklyn College, found that individuals who did not purchase their contact lenses from an eye doctor, but from an online site or store, are potentially placing themselves at greater risk. The findings indicated that online and store purchasers (consumers who get their contacts at a wholesale club or optical chain outlet) are less likely to adhere to healthy eye care practices, as recommended by their eye doctor.
Researchers uncover key trigger for potent cancer-fighting marine product
An unexpected discovery in marine biomedical laboratories at Scripps Institution of Oceanography at UC San Diego has led to new, key information about the fundamental biological processes inside a marine organism that creates a natural product currently being tested to treat cancer in humans. The finding could lead to new applications of the natural product in treating human diseases. more
Researchers use neuroimaging to study ESP
Psychologists at Harvard University have developed a new method to study extrasensory perception that, they argue, can resolve the century-old debate over its existence. According to the authors, their study not only illustrates a new method for studying such phenomena, but also provides the strongest evidence yet obtained against the existence of extrasensory perception, or ESP. more
Treatment with NAC is associated with better outcomes for children with liver failure
A new retrospective study on the effects of N-acetylcysteine (NAC) on children with acute liver failure not caused by acetaminophen poisoning has found that the treatment was associated with a shorter hospital stay, higher incidence of liver recovery, and better survival after transplantation. The study is in the January issue of Liver Transplantation, a journal by John Wiley & Sons. more

The dopamine transporter gene influences alcohol withdrawal seizures
The physiological component of alcoholism is defined by tolerance and/or withdrawal: the more severe the dependency on alcohol, the more severe the clinical complications, such as greater intensity and/or complications of alcohol withdrawal. A new study of polymorphisms – two or more mutually exclusive forms or alleles – within the dopamine transporter (DAT1) gene has shown that four of them are associated with withdrawal seizures.
Catheter chaos: Hospitals lag in preventing common infection
One in four Americans in the hospital right now has a urinary catheter. One percent of them will get a urinary tract infection from that catheter. All of those will require antibiotics. A few may suffer life-threatening complications. more
