Lasers might lead to cure for brain diseases such as Alzheimer's and Parkinson's

Posted: 03 Nov 2013 11:03 AM PST

Researchers have made a discovery that may lead to the curing of diseases such as Alzheimer's, Parkinson's and Creutzfeldt-Jakob disease (the so called mad cow disease) through photo therapy.

Scientists unlock secrets of diabetes drug

Posted: 03 Nov 2013 11:02 AM PST

The key to the drug metformin is that it doesn't work to lower blood glucose by directly working on the glucose. It works on reducing harmful fat molecules in the liver, which then allows insulin to work better and lower blood sugar levels.

Is DNA From Mom or Dad? New technique will accelerate personalized medicine

Posted: 03 Nov 2013 11:02 AM PST

A new technique successfully takes on a longstanding challenge in DNA sequencing – determining whether a particular genetic sequence comes from an individual's mother or father. The method promises to accelerate studies of how genes contribute to disease, improve the process of matching donors with organs and help scientists better understand human migration patterns.

Molecular link between gut microbes, intestinal health

Posted: 03 Nov 2013 11:01 AM PST

Humans maintain a symbiotic relationship with the trillions of beneficial microbes that colonize their bodies. Inflammatory bowel disease is one of the best-studied diseases associated with alterations in the composition of beneficial bacterial populations. Researchers have identified that the enzyme HDAC3 – important in epigenetics - is a key mediator in maintaining proper intestinal integrity and function in the presence of friendly bacteria.

How nanotechnology can advance regenerative medicine

Posted: 03 Nov 2013 10:57 AM PST

Nanotechnology may provide new strategies for regenerative medicine, including better tools to improve or restore damaged tissues.

Neuroimaging study sheds light on mechanisms of cognitive fatigue in MS

Posted: 01 Nov 2013 02:24 PM PDT

A new study sheds light on the mechanisms underlying cognitive fatigue in multiple sclerosis. This is the first study to use neuroimaging to investigate aspects of cognitive fatigue. Identifying a network of fatigue-related brain regions could help define the pathophysiology of this multifaceted symptom.

Anti-aging strategies can improve more than looks

Absence of vision from birth leads to a permanent state of pain hypersensitivity, reports a new study.

Constellation in the chaos of cancer chromosomes

Posted: 01 Nov 2013 09:53 AM PDT

New evidence suggests that aneuploidy patterns of chromosome deletion or amplification that are recurrent among tumors actually represent a driving force during tumor evolution and are very frequent in cancer.

Heart valve leakage: A new treatment for patients at high risk of cardiac surgery

Posted: 01 Nov 2013 06:19 AM PDT

Recent examination of current percutaneous techniques sheds light on the complexities of the treatment of paravalvular prosthetic regurgitation, or heart valve leakage. This research represents new advances for patients who have few or no surgical options.

Poor children grow up more susceptible to catching colds, study finds

Posted: 01 Nov 2013 06:19 AM PDT

Researchers have found an association between lower socioeconomic status during childhood and adolescence and the length of telomeres, protective cap-like protein complexes at the end of chromosomes, that ultimately affects the susceptibility to colds in middle-aged adults. Published in Brain, Behavior and Immunity, the study showed that children and teens with parents of lower socioeconomic status have shorter telomeres as adults.

Home visits lessen emergency care for infants

Posted: 01 Nov 2013 06:19 AM PDT

Home visits from a nurse are a proven but expensive way to help newborns get a good start in life. New research suggests that less costly home visiting programs can reach more families and still produce significant health care improvements. Infants in the study had 50 percent fewer emergency care episodes than other babies in the first year of life.

Scientists raise alarm over today's measures against Legionellosis

Posted: 01 Nov 2013 06:17 AM PDT

According to the textbooks, both high doses of chlorine and hot water are lethal to legionella bacteria. But now Norwegian scientists are sounding the alarm that the bacteria can survive these treatments, by hiding in amoebae.

Nationwide disparities of deaths reported to coroners, British study suggests

Posted: 01 Nov 2013 06:17 AM PDT

A leading detective turned university researcher has discovered huge nationwide disparities in the numbers of deaths reported to coroners in the United Kingdom. It could mean that in some areas, inquests into unnatural deaths are not being conducted when they might have been deemed necessary elsewhere. Also, it has emerged that deaths of women are less likely to be reported and go to inquest - and when they do, they are less likely to result in a verdict of unnatural death.

Posted: 31 Oct 2013 05:34 PM PDT

A twenty percent tax on sugar sweetened drinks would reduce the number of UK adults who are obese by 180,000 (1.3 percent) and who are overweight by 285,000 (0.9 percent), suggests a British study.

Mid-level health workers as effective as physicians

Posted: 31 Oct 2013 05:34 PM PDT

Countries facing severe shortages and poor distribution of health workers could benefit from training and deploying more mid-level health workers, such as midwives, nurses, medical assistants and surgical clinicians.In countries where such health workers have been deployed, the clinical outcomes for certain services were just as good and -- in some cases -- even better than when physicians performed them, the study shows.
