Minimally invasive alternative to corneal transplantation may improve outcomes in people with a degenerative eye disease Posted: 18 Oct 2016 10:26 AM PDT An innovative procedure may improve outcomes in people with a degenerative eye disease, suggest five-year results from a new study. Transplantation of one layer of the cornea may help people with keratoconus avoid or delay full corneal transplantation and other potentially risky procedures, according to the researchers. They say the technique may enable those with advanced keratoconus to tolerate extended contact lenses wear, which is traditionally a challenge for people with the condition.

Migraine sufferers have more nitrate-reducing microbes in their mouths Posted: 18 Oct 2016 10:26 AM PDT The mouths of migraine sufferers harbor significantly more microbes with the ability to modify nitrates than people who do not get migraine headaches, new research has found.

Exposure to chemicals dangerous to hormone function burdens Americans with hundreds of billions in disease costs Posted: 18 Oct 2016 07:36 AM PDT Annual healthcare costs and lost earnings in the United States from low-level but daily exposure to hazardous chemicals commonly found in plastic bottles, metal food cans, detergents, flame retardants, toys, cosmetics, and pesticides, exceeds $340 billion, according to a detailed economic analysis.

Study finds mixed results for use of mesh for hernia repair Posted: 18 Oct 2016 06:49 AM PDT Among patients undergoing incisional hernia repair, the use of mesh to reinforce the repair was associated with a lower risk of hernia recurrence over 5 years compared with when mesh was not used, although with long-term follow-up, the benefits attributable to mesh were offset in part by mesh-related complications, according to a study.

Some is good, more is better: Regular exercise can cut your diabetes risk Posted: 18 Oct 2016 06:49 AM PDT Walking briskly or cycling for the recommended 150 minutes a week can reduce a person's risk of developing type 2 diabetes by up to 26%, according to new research.

Gene links risk of psychiatric disease to reduced synapse numbers Posted: 18 Oct 2016 06:47 AM PDT Mutations in a gene linked with brain development may dispose people to multiple forms of psychiatric disease by changing the way brain cells communicate, new research has revealed.

Scientists developing MRI-guided neural stem cell delivery method Posted: 18 Oct 2016 06:47 AM PDT Scientists are aiming to develop a more effective method for delivering neural stem cells to the brain in an effort to move forward stem cell therapies to treat neurological disorders.

New receptors discovered for stomach germ Helicobacter pylori Posted: 18 Oct 2016 06:42 AM PDT Helicobacter pylori is a spiral bacterium that can colonize the human stomach, sometimes with fatal consequences. A research group has discovered a completely new approach to preventing or treating infections with this bacterium as well as secondary complications.

Depression's physical source discovered Posted: 18 Oct 2016 06:41 AM PDT Understanding of the physical root of depression has been advanced, thanks to new research. Researchers have identified the lateral orbitofrontal cortex as the area of the brain affected by depression. This discovery could open up possible new treatments, say the researchers.

Why prostate cancer cells develop resistance to treatment Posted: 18 Oct 2016 06:41 AM PDT A standard hormone supplement, used to boost energy levels in prostate cancer patients following radiotherapy, could potentially increase the chances of the cancer returning, a new study has shown.

New evidence that hormone levels measured in hair can affect IVF success by almost one-third Posted: 18 Oct 2016 06:41 AM PDT Levels of a hormone when measured in hair can significantly predict the likelihood of pregnancy in women undergoing in vitro fertilization (IVF) treatment, scientists have revealed.

Why is skin thick on the soles of the feet? Posted: 18 Oct 2016 06:41 AM PDT A team of researchers has established a method for capturing live, three-dimensional, high-resolution images deep within the skin of living mice, casting light on the precise manner in which cells divide to maintain the thick outer layer of skin.

Study reveals high levels of vitamin D inadequacy in UK adolescents Posted: 18 Oct 2016 06:38 AM PDT A new study finds high prevalence of vitamin D inadequacy in 14 to 18 year olds at a time of the year when vitamin D levels should be at their peak (post-summer). The research identifies the level of vitamin D intake needed by adolescents to avoid vitamin D deficiency and ensure adequacy. Vitamin D plays an essential role in bone growth during adolescent years, helping to achieve peak bone mass by late adolescence – believed to contribute to reducing age-related bone loss in later life. Results of study, led by the University of Surrey, published in the American Journal of Clinical Nutrition

Virtual experience gets the elderly to exercise Posted: 18 Oct 2016 06:38 AM PDT Virtual Reality can get the elderly in nursing homes to be happier about exercising. A new research project shows that the technology motivates older people in nursing homes to get moving.

Peptides vs. superbugs Posted: 18 Oct 2016 06:38 AM PDT Several peptides have an antibacterial effect - but they are broken down in the human body too quickly to exert this effect. Researchers have now succeeded in encasing peptides in a protective coat, which could prolong their life in the human body. This is an important breakthrough because peptides are considered to be a possible solution in the fight against antibiotic-resistant bacteria.
