Research on treatments for advanced ovarian cancer Posted: 26 Feb 2016 02:32 PM PST New research supports the use of weekly chemotherapy without bevacizumab in treating advanced ovarian cancer.

Breast reconstruction using abdominal tissue: Differences in outcome with four different techniques Posted: 26 Feb 2016 02:31 PM PST In women undergoing breast reconstruction using their own (autologous) tissue, newer 'muscle-sparing' abdominal flaps can reduce complications while improving some aspects of quality of life, reports a new study.

Potential treatment for Huntington's disease, found effective, safe in mice, monkeys Posted: 26 Feb 2016 02:31 PM PST A drug that would be the first to target the cause of Huntington's disease is effective and safe when tested in mice and monkeys, according to data released today. A study to test the drug in humans has begun.

New promise for patients with primary progressive multiple sclerosis Posted: 26 Feb 2016 12:04 PM PST Abstract describes efficacy of ocrelizumab in patients with PPMS with and without T1 gadolinium-enhancing lesions at baseline in a Phase III, placebo-controlled trial.

Insecticide-treated nets may still prevent malaria despite mosquito resistance Posted: 26 Feb 2016 11:39 AM PST Insecticide-treated nets may still help prevent malaria despite mosquitoes developing resistance, which may provide a clue to why it has been hard to demonstrate the impact of this resistance on malaria as a public health problem, according to new research.

Metabolism protein found to also regulate feeding behavior in the brain Posted: 26 Feb 2016 10:38 AM PST Feeling hungry or full leads us to change how much we eat, but the molecular wiring of this process is not well understood. Scientists have identified a new player in this circuit called amylin, which contributes to reducing food consumption in mice.

Being overweight linked to poorer memory Posted: 26 Feb 2016 10:38 AM PST Overweight young adults may have poorer episodic memory -- the ability to recall past events -- than their peers, suggests new research, adding to increasing evidence of a link between memory and overeating. Researchers found an association between high body mass index and poorer performance on a test of episodic memory.

Drug discovery paradigm targets Tau protein aggregation linked to the Alzheimer's disease Posted: 26 Feb 2016 08:52 AM PST New research demonstrates novel drug discovery paradigm to target the aggregation of the Tau protein linked to the onset of Alzheimer's and other related neurodegenerative diseases.

Homeless people suffer geriatric conditions decades early, study shows Posted: 26 Feb 2016 05:57 AM PST Homeless people in their fifties have more geriatric conditions than those living in homes who are decades older, according to researchers who are following 350 people who are homeless and aged 50 and over, in Oakland.

Researchers develop 3-D printed diagnostic device that can rapidly detect anemia Posted: 26 Feb 2016 05:15 AM PST Researchers are using 3-D printers to develop a low cost, point-of-care device that can quickly detect anemia. Anemia is a condition in which the blood does not have enough healthy red blood cells to transport oxygen to the body's organs. It affects 2 billion people worldwide, including more than half of preschool children and pregnant women in developing countries and at least 30 percent of children and women in industrialized nations.

Transgender children supported in their identities show positive mental health Posted: 26 Feb 2016 05:15 AM PST A new study, believed to be the first to look at the mental health of transgender children who have "socially transitioned," finds that they had rates of depression and anxiety no higher than two control groups of children. The findings challenge long-held assumptions that mental health problems in transgender children are inevitable, or even that being transgender is itself a type of mental disorder.

New research adds additional layer of complexity to human protein landscape Posted: 26 Feb 2016 05:13 AM PST New research adds an extra dimension to the known set of human proteins. Genes can shift their expression towards alternative protein versions (proteoforms) that rival their full length counterparts in stability. For that reason, the diversity of human proteins seems to be fundamentally underestimated, and the single gene-single protein theory has once again debunked.

Wristband and an app for a better back Posted: 26 Feb 2016 05:11 AM PST You may think you are doing the right back exercises to help your back pain, but a new app coupled with a wristband will help you—and your doctors—to figure out if this is true.

Scientists make significant anti-aging breakthrough Posted: 26 Feb 2016 05:09 AM PST A breakthrough in understanding human skin cells offers a pathway for new anti-aging treatments.

Engineering music to sound better with cochlear implants Posted: 25 Feb 2016 03:16 PM PST Scientists are trying to reengineer and simplify music to be more enjoyable for listeners with cochlear implants.

Annual plastic surgery statistics reflect the changing face of plastic surgery Posted: 25 Feb 2016 03:16 PM PST The annual plastic surgery procedural statistics show that in 2015 there were 15.9 million surgical and minimally invasive cosmetic procedures performed in the United States -- up 2 percent from 2014.

Machine learning at arraignments can cut repeat domestic violence Posted: 25 Feb 2016 12:36 PM PST Researchers have found that using machine learning at arraignments can cut repeat domestic violence.

Proofreading molecules tug on RNA to ensure protein production accuracy Posted: 25 Feb 2016 12:36 PM PST Scientists have discovered how two enzymes play a critical role in ensuring quality control during splicing. In a new study, they found these molecules most likely apply physical tension to RNA to keep wrong sites from being cut. This action not only prevents splicing errors, it also enables the selection of alternative splicing sites.

Tests show no specific gastrointestinal abnormalities in children with autism Posted: 25 Feb 2016 12:36 PM PST Children with autism have no unique pattern of abnormal results on endoscopy or other tests for gastrointestinal (GI) disorders, compared to non-autistic children with GI symptoms.

Zika virus linked to stillbirth, other symptoms in Brazil Posted: 25 Feb 2016 12:34 PM PST In January, a pregnant Brazilian woman infected with the Zika virus had a stillborn baby who had signs of severe tissue swelling as well as central nervous system defects that caused near-complete loss of brain tissue. It is the first report to indicate a possible association of congenital Zika virus and damage to tissues outside the central nervous system, say researchers.

Only a small portion of synapses may be active during neurotransmission, study finds Posted: 25 Feb 2016 11:04 AM PST A new optical technique shows how information is transmitted in the brains of mice. Using this method, they found that only a small portion of synapses -- the connections between cells that control brain activity -- may be active at any given time.

Chemists expose side effects of antimalarial drug Posted: 25 Feb 2016 11:04 AM PST The drug chloroquine has long been used to treat malaria, but it is not without side effects. To better understand how chloroquine toxicity occurs, medical researchers set out to investigate what the drug binds to in human cells.

3-D technology used to safely reveal the diet of 'Chaucer's children' Posted: 25 Feb 2016 11:02 AM PST Biological anthropologists have discovered a new way of examining the fragile teeth of children who lived between the 11th and 15th centuries without damaging them. By using 3-D microscopic imaging, researchers have been able to safely reconstruct the diet of children who would have lived next door to Canterbury Cathedral when Chaucer was writing his famous Tales.

Let it go: Reaction to stress more important than its frequency Posted: 25 Feb 2016 11:02 AM PST How you perceive and react to stressful events is more important to your health than how frequently you encounter stress, according to health researchers.

Post-Ebola syndrome in Sierra Leone Posted: 25 Feb 2016 11:00 AM PST Researchers have conducted a study of Ebola survivors to describe the medical problems they continue to have after recovering from the acute disease.

Fish brains help explain human sensory perception Posted: 25 Feb 2016 10:57 AM PST Advanced calcium imaging of zebrafish brains is helping researchers discover how sensory stimuli such as sights and sounds are integrated in the human brain.

Collection of open reading frames at 80 percent of human protein-coding genes Posted: 25 Feb 2016 10:57 AM PST An international collaboration of organizations has reached a milestone in creating a library of complete genetic blueprints for the thousands of different proteins in human cells.
