A team of researchers from the United States and Germany has discovered the molecular map that is linked with the development of cataracts. The researchers have discovered that cataracts may be born of an imbalance between three proteins that aid in the focusing of the eye. Two of the proteins are active, while the third works as a "chaperone," regulating the chemical balance between the three.
A sugar-free candy has been developed by researchers that allows helpful oral bacteria to flourish, potentially preventing cavities, according to the German manufacturer Organobalance. The animal study, published in Probiotics and Antimicrobial Proteins, noted that harmful bacteria on the teeth releases acid which damages tooth enamel.
Those suffering from dementia may benefit greatly from increasing their amount of exercise, according to a new study from researchers at the University of Alberta in Edmonton, Canada. The researchers reviewed data from 19 previous studies with over 900 patients and found that those dementia patients who had the most exercise reported the highest benefits to overall lifestyle.
Energy drinks high in caffeine and taurine can significantly increase the heart rate, according to research presented at the annual meeting of the Radiological Society of North America. "Usually energy drinks contain taurine and caffeine as their main pharmacological ingredients," Dr. Dörner of the University of Bonn said at the meeting.
Pig kidneys may be a key to the future of treatment for humans needing kidney transplants, according to researchers from the University of Florida. Researchera are examining how pig kidneys can serve as a frame which could grow into human kidneys when combined with human stem cells. In the process, the pig kidney is first stripped of all its own cells, leaving a translucent frame work.
Low levels of Vitamin D in one's diet may result in brain damage, according to research at the University of Kentucky. The animal study, published in Free Radical Biology and Medicine, showed that rats fed a vitamin D-deficient diet developed free radical brain damage. The rats with the low vitamin D diet also showed poor performance on tests of learning and memory.
Leg compression stockings may be as effective in eliminating legs ulcers as traditional multi-layer bandages, according to a new study from researchers at the University of Manchester's School of Nursing, Midwifery and Social Work in the UK. Researcher enlisted more than 450 leg ulcer patients, treating half the group with traditional bandages and half with compression stockings.
Sovaldi, a new hepatitis C drug developed by Gilead Sciences Inc., has been approved by the FDA. In clinical trials, Sovaldi cured close to 90 percent of patients in 12 weeks, compared to a 75 percent mark with older drugs. According to BMO Capital Markets, Sovaldi is expected to see sales of $1.9 billion next year.
The presence of the protein ERG in prostate tissue greatly increases the chance of prostate cancer, according to research conducted at Cornell University. The study, published in the Journal of Clinical Oncology, reported that 53% of men whose prostate biopsies showed expression of ERG protein developed invasive prostate cancer.
A new test for certain strains of the flu makes use of both sugar and gold to detect the virus within a 30 minute period, according to researchers from the University of East Anglia in the U.K. The new test is based on a similar process already at use for detecting cholera. With the cholera test, molecules of the virus are drawn out using a carbohydrate recognition process.
It may be far more expensive to maintain a healthy diet than an unhealthy diet, according to researchers from the Harvard School for Public Health. For the study the researchers reviewed data collected from 10 wealthy nations between 2000 and 2011. They found that on average, those who maintain a healthy diet rich in fruits, vegetables and whole grains are spending about $550 more a year.
The CDC has released an official statement noting that while the measles virus has been eradicated since 2011, it could still pose a threat to the public. According to a new study, the CDC warns that while the disease is largely controlled within the U.S., the public is still at risk from those who travel outside the country.
Fruit flies with better sex lives live longer than their frustrated counterparts, according to research conducted at the University of Michigan. The study, published in the journal Science, looked at male flies that perceived sexual interest from females only to be denied. The sexually frustrated flies lived shorter lives.
Cervical cancer screenings, also known as Pap tests, may be overused in some groups of women - especially those who've had hysterectomies and those over the age of 65 with no history of cervical cancer. Dr. Deanna Kepka from the Huntsman Cancer Institute says that testing these groups has meant about 14 million tests for women who didn't need them.
Mutation of a single gene, Elfn1, has been shown to cause symptoms characteristic of attention-deficit hyperactivity disorder, according to research at Trinity College Dublin. The animal study, published in the journal PLOS ONE, examined the role of the gene by removing it from a group of mice and comparing their behavior with a group of mice with a normal functioning Elfn1 gene.
