Leadership void, not lack of money, slows efforts to address cervical cancer Posted: 03 Nov 2013 11:06 AM PST A study by health researchers found that the opportunity for significant progress in addressing cervical cancer across the United States is being squandered -- not because of a lack of money, but because of a void of leadership and organization at the state levels.

Nanotube-based sensors can be implanted under the skin for a year Posted: 03 Nov 2013 11:06 AM PST Research shows that carbon nanotubes that detect nitric oxide can be implanted under the skin for more than a year.

Scientists expose molecular secrets of bile duct cancers from different countries Posted: 03 Nov 2013 11:06 AM PST New molecular insights point to potentially different treatment regimens for the same cancer type depending on underlying genetic alterations. The discovery came after bile duct cancers were compared from different parts of the world.

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.

Life, but not as we know it: Rudimentary form of life sidesteps normal replication process Posted: 03 Nov 2013 11:02 AM PST A rudimentary form of life that is found in some of the harshest environments on Earth is able to sidestep normal replication processes and reproduce by the back door, researchers have found.

Important mechanism behind nanoparticle reactivity discovered Posted: 03 Nov 2013 11:02 AM PST An international team of researchers has used pioneering electron microscopy techniques to discover an important mechanism behind the reaction of metallic nanoparticles with the environment.

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 Posted: 01 Nov 2013 02:23 PM PDT Experts have advice on how to slow aging, and how this can help with appearance and self-esteem.

Congenital blindness results in lower thermal pain thresholds Posted: 01 Nov 2013 09:54 AM PDT 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.

Botox to treat 'suicide' headaches Posted: 01 Nov 2013 06:17 AM PDT A pilot study is under way, testing a new treatment using botox on sufferers of severe and debilitating headaches, often referred to as suicide headache, because many sufferers become suicidal.

Breakthrough in identifying effect of epilepsy treatment Posted: 31 Oct 2013 05:34 PM PDT Fifty years after valproate was first discovered, research published reports how the drug works to block seizure progression.

Twenty percent sugary drink tax would cut number of UK obese adults by 180,000 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.

Knowing who physician is boosts patient satisfaction Posted: 31 Oct 2013 02:56 PM PDT Knowing who your doctor is -- and a couple of facts about that person -- may go a long way toward improving patient satisfaction.
