Boosting productivity at work may be simple: Stand up Posted: 25 May 2016 07:05 PM PDT Most people have heard the argument that standing desks are good for the body. They can help burn more calories and fight obesity. Standing can even help improve students' attention and cognitive functioning. Now, new research indicates that they may boost productivity in adults as well.

Multiple personality disorder may be rooted in traumatic experiences Posted: 25 May 2016 07:00 PM PDT A new study supports the notion that multiple personality disorder is rooted in traumatic experiences such as neglect or abuse in childhood, rather than being related to suggestibility or proneness to fantasy.

Genome sequencing provides diagnosis for some types of intellectual disability Posted: 25 May 2016 07:00 PM PDT A study is one of the first to show the life-changing benefits of genome-wide sequencing for children with certain kinds of intellectual disability, report scientists.

Prenatal fruit consumption boosts babies' cognitive development Posted: 25 May 2016 01:15 PM PDT The benefits of eating fruit can begin as early as in the womb. A new study, using data from nearly 700 Edmonton children, demonstrates that infants do significantly better on developmental tests when their mothers consume more fruit during pregnancy.

Study reveals protein that dials immune responses up and down Posted: 25 May 2016 01:15 PM PDT New research has identified a new regulator of immune responses. The study sheds new light on why T cells fail to clear chronic infections and eliminate tumors.

Is symptom expression a form of communication? Posted: 25 May 2016 01:13 PM PDT Organisms, including humans, express or suppress symptoms of illness based on need, a new report indicates. Symptoms of illness are not inevitably tied to an underlying disease --rather, many organisms, including humans, adapt their symptom expression to suit their needs, the author suggests.

Human amyloid-beta acts as natural antibiotic in the brain: Alzheimer's-associated amyloid plaques may trap microbes Posted: 25 May 2016 01:13 PM PDT A new study provides additional evidence that amyloid-beta protein -- which is deposited in the form of beta-amyloid plaques in the brains of patients with Alzheimer's disease -- is a normal part of the innate immune system, the body's first-line defense against infection.

Scientists block breast cancer cells from hiding in bones Posted: 25 May 2016 01:13 PM PDT A molecular key that breast cancer cells use to invade bone marrow in mice, where they may be protected from chemotherapy or hormonal therapies that could otherwise eradicate them, has been discovered by a team of researchers. Through years of experiments in mice, the scientists have found ways to outmaneuver this stealth tactic by not only preventing breast cancer cells from entering the bone marrow, but also by flushing cancer cells out into the blood stream where they could be targeted for destruction.

Humiliation from stares are worse than tiny seats for obese air travelers, new study Posted: 25 May 2016 11:07 AM PDT Feelings of shame and humiliation bother obese air passengers more than tight seat belts and tiny seats, according to a new study.

First large-scale proteogenomic study of breast cancer provides insight into potential therapeutic targets Posted: 25 May 2016 11:07 AM PDT A new study integrates genomic and proteomic data to yield a more complete picture of cancer biology than either analysis could do alone, report scientists.

Scientists capture the elusive structure of essential digestive enzyme Posted: 25 May 2016 11:07 AM PDT Researchers have revealed new structural data that has eluded scientists for years on a liver enzyme that is critical for human health.

Dose of transplanted blood-forming stem cells affects their behavior Posted: 25 May 2016 11:05 AM PDT Unlike aspirin, bone marrow doesn't come with a neatly printed label with dosage instructions. However, a new study provides clues about how the dose of transplanted bone marrow might affect patients undergoing this risky procedure, frequently used to treat cancer and blood diseases.

Out of tune: Mismatch of vascular, neural responses suggests limits of fMRI Posted: 25 May 2016 11:05 AM PDT During sensory stimulation, increases in blood flow are not precisely 'tuned' to local neural activity, report investigators. This finding challenges the long-held view that vascular and local neural responses are tightly coupled and could suggest limitations for functional magnetic resonance imaging, which assumes that vascular changes reflect a proportional change in local neural activity.

Dialing up chemotherapy for pancreatic cancer with ultrasound Posted: 25 May 2016 11:05 AM PDT By enhancing the ability of cells to absorb chemotherapeutics, researchers have nearly doubled the median patient survival time from diagnosis in a phase I clinical trial. Researchers have combined a laboratory ultrasound technique called 'sonoporation' with the commercially-available chemotherapy compound Gemcitabine to increase the porosity of pancreatic cells with microbubbles and to help get the drug into cancer cells where it is needed.

Scientists show commonly prescribed painkiller slows cancer growth Posted: 25 May 2016 10:26 AM PDT Scientists have found that one of the most widely prescribed pain and anti-inflammation drugs slows the growth rate of a specific kind of cancer in animal models and suggests the medication could have the same effect on other types of tumors.

Full-incision facelift superior to short-scar in neck region, study in multiples shows Posted: 25 May 2016 09:28 AM PDT Facelift patients who wish to avoid the dreaded 'turkey wattle' neckline years later should undergo a full-incision surgical technique instead of a short-scar method, according to novel new research who performed the procedure on identical twins and triplets.

Neuroscientists illuminate role of autism-linked gene Posted: 25 May 2016 09:12 AM PDT Neuroscientists have found that loss of the autism-linked Shank gene prevents brain synapses from maturing, in a study of fruit flies. Many genetic variants have been linked to autism, but only a handful are potent enough to induce the disorder on their own. Among these variants, mutations in a gene called Shank3 are among the most common, occurring in about 0.5 percent of people with autism.

Anemia negatively affects recovery from traumatic brain injuries Posted: 25 May 2016 09:12 AM PDT Approximately half of patients hospitalized with traumatic brain injuries are anemic, according to recent studies, but anemia's effects on the recovery of these patients is not clear. Now, researchers have found evidence that anemia can negatively influence the outcomes of patients with traumatic brain injuries.

Investigating how 'chemo brain' develops in cancer patients Posted: 25 May 2016 09:12 AM PDT During and after chemotherapy, many cancer patients describe feeling a mental fog, a condition that has been dubbed 'chemo brain.' Why this happens is unclear, but researchers have found a new clue to understanding this syndrome. A new study reports that chemotherapy in rats affects their chemical messengers dopamine and serotonin, which are associated with cognition.

What can Pavlov's dogs tell us about drinking? Posted: 25 May 2016 09:12 AM PDT Pavlovian cues that predict alcohol can lead us toward addiction. And sometimes those cues can become desirable in and of themselves, as shown in a new study.

No dessert for you! When it comes to diabetes, 'nagging is caring' Posted: 25 May 2016 09:12 AM PDT For men, an unhappy marriage may actually slow the development of diabetes and promote successful treatment once they do get the disease, finds an American study.

Monitoring sun exposure with a portable paper sensor Posted: 25 May 2016 09:11 AM PDT Summer is around the corner -- time for cookouts and sunbathing. But too much sun can result in sunburn, which is the main cause of skin cancer. Because the time it takes to get burned depends on many factors, it is not easy to tell when to seek shade. To help people stay safe, researchers report the development of a paper-based sensor for monitoring sun exposure given different skin tones and sunscreen levels.

Students design prosthetic foot for high heels Posted: 25 May 2016 08:41 AM PDT After losing a leg to injury or disease, women adjusting to life with a prosthetic limb face the same challenges as men, with perhaps one added complication: how to wear high-heels? Students have developed an early version of a potential solution.

Fixing cystic fibrosis: In vitro studies show therapeutically robust correction of the most common CF gene mutation Posted: 25 May 2016 08:41 AM PDT In experiments with isolated cystic fibrosis lung cells, researchers have partially restored the lost function of those cells to therapeutic levels.

Study examines suicide attempt risk factors, methods and timing, related to deployment among active duty soldiers Posted: 25 May 2016 08:41 AM PDT Suicide attempts, like suicides, have increased in the U.S. Army over the last decade. To better understand and prevent suicidal behavior, researchers examined timing and risk factors for suicide attempts among U.S. Army enlisted Soldiers. They found the highest risk was among those who never deployed, and those who never deployed were at greatest risk during their second month of service.

Antiretroviral therapy may not be enough to reduce HIV-associated arterial inflammation Posted: 25 May 2016 08:39 AM PDT Initiating antiretroviral therapy soon after diagnosis of an HIV infection did not prevent the progression of significant arterial inflammation in a small group of previously untreated patients.

Study finds elevated cancer risk among women with new-onset atrial fibrillation Posted: 25 May 2016 08:39 AM PDT Among nearly 35,000 initially healthy women who were followed-up for about 20 years, those with new-onset atrial fibrillation had an increased risk of cancer, according to a new study.

Lung function may affect vocal health for women Posted: 25 May 2016 08:12 AM PDT Vocal fatigue is a common complaint among teachers and one of the most debilitating conditions that can lead to vocal damage. The typical symptoms include hoarseness, vocal tiredness, muscle pains and lost or cracked notes. However, the actual physiological mechanism of vocal fatigue is still being explored. Now, a group of researchers have found a potential link between pulmonary function and the symptoms of voice fatigue unique to women, the predominate population of teaching workforce.

Researchers make a key discovery in how malaria evades the immune system Posted: 25 May 2016 07:21 AM PDT The malaria parasite Plasmodium falciparum hijacks an immune system process to invade red blood cells, according to a study. Understanding how malaria invades the cells could lead to a more effective vaccine.

Consumer knowledge gap on genetically modified food Posted: 25 May 2016 07:21 AM PDT While consumers are aware of genetically modified crops and food, their knowledge level is limited and often at odds with the facts, according to a newly published study.

Blockade of histamine receptors suppresses intestinal anaphylaxis in peanut allergy Posted: 25 May 2016 07:17 AM PDT Simultaneous pre-treatment with antihistamines that block both the H1 and H4 antihistamine receptors suppressed the gastrointestinal symptoms of food allergy in mice, according to researchers.

Revealed mechanism for inhibiting bacterial invasion of colonic epithelia Posted: 25 May 2016 07:17 AM PDT A group of researchers has elucidated how a gene named Ly6/Plaur domain containing 8 (Lypd8) inhibits bacterial invasion of colonic epithelia, regulating intestinal inflammation. This achievement may lead to the development of drugs for ulcerative colitis.

Will heart medication help treat Alzheimer's disease? Posted: 25 May 2016 05:47 AM PDT Heart medication reduces the build-up of plaque in the brain's blood vessels in mice, new research shows. The question is if this is true also in humans; if the answer is yes, it might bring scientists a step closer to developing a medicine against Alzheimer's disease.

Workaholism tied to psychiatric disorders Posted: 25 May 2016 05:45 AM PDT Workaholism frequently co-occurs with ADHD, OCD, anxiety, and depression, a large national Norwegian study shows. The study showed that workaholics scored higher on all the psychiatric symptoms than non-workaholics.

New multiphoton microscope and endoscope could speed up disease diagnosis Posted: 25 May 2016 05:45 AM PDT Two new optical devices could reduce the need to take tissue samples during medical examinations and operations and to then send them for testing – potentially speeding up diagnosis and treatment and cutting healthcare costs.

Understanding the underlying mechanisms that lead to psoriasis Posted: 25 May 2016 05:45 AM PDT Psoriasis is an inflammatory skin condition that affects some 125 million people worldwide. It is characterized by itchy, scaly skin plaques. The exact cause of psoriasis is unclear. But mounting evidence implicates the immune system in the overproduction of cell-signalling molecules called cytokines, which stimulate skin cells called keratinocytes to express genes that maintain an inflammatory microenvironment. Now, scientists have found more evidence that a cytokine called IL-17A is especially critical in this process.

Lung cancer survival rate increases by 73 percent if caught early Posted: 25 May 2016 05:39 AM PDT The UK Lung cancer screening trial has been successfully completed and has demonstrated that patients with a high risk of developing lung cancer can be identified with early stage disease and have up to a 73 percent chance of surviving for five years or more.

Zika virus may be linked to more eye problems in Brazilian babies with microcephaly Posted: 25 May 2016 05:39 AM PDT Researchers studying babies with a Zika virus-related birth defect say they have found previously unreported eye problems possibly linked to the virus. In three Brazilian infants with microcephaly, the researchers observed retinal lesions, hemorrhaging and abnormal blood vessel development not noted before in relation to the virus.

As early as first grade, children with severe obesity are more likely to be ostracized Posted: 25 May 2016 05:39 AM PDT As early as first grade, severely obese children are more likely to be rejected by peers and show signs of depression, new research indicates. Today, approximately one in 20 children in the United States is severely obese and this public health threat costs the U.S. government billions of dollars annually.

Children's social, academic functioning is impeded when their families move more often Posted: 25 May 2016 05:39 AM PDT A new study analyzing a nationally representative US sample of 19,162 children, has found that frequent residential moves can lead to a decline in academic performance as well as higher rates of emotional and behavioral problems.

Study shows area undamaged by stroke remains so, regardless of time stroke is left untreated Posted: 25 May 2016 05:39 AM PDT A new study looked at a group of untreated acute stroke patients and found that there was no evidence of time dependence on damage outcomes for the penumbra, or tissue that is at risk of progressing to dead tissue but is still salvageable if blood flow is returned in a stroke, but rather an association with collateral flow -- or rerouting of blood through clear vessels.

Do dressings prevent infection? Posted: 24 May 2016 06:20 PM PDT There is insufficient evidence to know whether dressings reduce the risk of wound infection after surgery and, in some cases, leaving a wound exposed may be better, say researchers.

Survey reveals few GPs use alternatives to face-to-face consultations Posted: 24 May 2016 06:20 PM PDT Despite policy pressure on GPs to offer consultations by email or internet video programs such as Skype, few GPs do and most have no plans to introduce them in future, according to a new study from the United Kingdom.

New study surveys genetic changes linked with Parkinson's disease Posted: 24 May 2016 06:20 PM PDT The genetic modifications associated with the development of Parkinson's disease (PD) and PD-associated dementia has been the focus of recent research, which is bringing new investigative tools to bear.

E-cigarette use in UK almost doubled in 2 years, says Europe-wide study Posted: 24 May 2016 06:18 PM PDT New research has examined e-cigarette use -- and attitudes to the devices -- across Europe between 2012 and 2014. The work found that the proportion of people in the UK who had tried an e-cigarette had increased from 8.9 percent to 15.5 percent -- higher than the European average.

'Suggestive evidence' for link between air pollution, heightened stillbirth risk Posted: 24 May 2016 06:18 PM PDT There is 'suggestive evidence' for a link between air pollution and a heightened risk of stillbirth, indicates a summary of the available data recently released.

Gaps in vaccine coverage highlighted with new report and online tool Posted: 24 May 2016 11:47 AM PDT As the 69th World Health Assembly discusses progress on the Global Vaccine Action Plan, a new data visualization platform, the Vaccine Information Epidemiology Window (VIEW-hub), identifies shortfalls in vaccine introduction and coverage. VIEW-hub uses real-time data updates to monitor introduction and implementation of PCV, Hib and rotavirus vaccines, enabling strategy development for accelerating progress on global and country levels.
