Researchers identify new cause of inherited neuropathy Posted: 23 Mar 2016 03:56 PM PDT Charcot-Marie-Tooth Disease is a family of inherited disorders of the peripheral nervous system, affecting approximately one in 2,500 Americans. Its most common iteration, CMT1, comes in many forms, most of which have to date been linked to a small set of causative genes. New research recently uncovered a new genetic cause of CMT1.

Modified maggots could help human wound healing Posted: 23 Mar 2016 03:56 PM PDT In a proof-of-concept study, researchers show that genetically engineered green bottle fly larvae can produce and secrete a human growth factor -- a molecule that helps promote cell growth and wound healing.

Digital health tool helps cardiac rehab patients shed more pounds Posted: 23 Mar 2016 03:56 PM PDT Adding a digital health tool to traditional cardiac rehabilitation appears to help people recovering from a heart attack lose significantly more weight in a relatively short period of time, according to new research.

Missed opportunities to avoid painful shocks at the end of life Posted: 23 Mar 2016 03:55 PM PDT Many patients who have a common medical device known as an implantable cardioverter defibrillator (ICD) are unaware that the device can be deactivated to prevent painful shocks in their final days of life.

Long naps, daytime sleepiness tied to greater risk of metabolic syndrome Posted: 23 Mar 2016 03:55 PM PDT Taking long naps or being excessively tired during the day is associated with a higher risk for developing metabolic syndrome, according to a new study.

Depression after heart disease diagnosis tied to heart attack, death Posted: 23 Mar 2016 03:55 PM PDT New research shows patients with a history of chest discomfort due to coronary artery disease -- a build up of plaque in the heart's arteries -- who are subsequently diagnosed with depression are much more likely to suffer a heart attack or die compared with those who are not depressed.

Two decades have brought little change for women in cardiology Posted: 23 Mar 2016 03:55 PM PDT Female cardiologists are less likely than their male counterparts to get married and have children and more likely to face challenges related to child care, family leave policies and professional discrimination, according to a new study.

Women, men with suspected heart disease have similar symptoms Posted: 23 Mar 2016 03:55 PM PDT Chest pain and shortness of breath are the most common symptoms reported by both women and men with suspected heart disease, a finding that is in contrast to prior data.

Statewide initiative associated with improved cardiac arrest outcomes Posted: 23 Mar 2016 03:55 PM PDT Statewide efforts to equip family members and the general public with the know-how and skills to use cardiopulmonary resuscitation (CPR) and automated external defibrillators (AEDs) in the home or in public coincide with improved survival and reduced brain injury in people with sudden cardiac arrest.

Many women not properly informed of heart risk by their doctors Posted: 23 Mar 2016 03:55 PM PDT Although nearly three-quarters of women taking a recent survey had one or more risk factors for heart disease, a startlingly small proportion -- just 16 percent -- had actually been told by their doctors that these factors put them at risk for heart disease.

The tougher men think they are, the less likely they are to be honest with doctors Posted: 23 Mar 2016 12:20 PM PDT Men are less likely than women to go to the doctor, more likely to choose a male doctor when they do go, but less likely to be honest with that doctor about their symptoms, psychologists have found. The researchers believe this may contribute to men's dying earlier than women.

Tooth loss increases the risk of diminished cognitive function Posted: 23 Mar 2016 12:20 PM PDT A team of researchers systematically assessed the association between oral health and cognitive function in adult populations, and found that there is an association between tooth loss and reduced cognitive function.

Unlocking the secrets of gene expression Posted: 23 Mar 2016 12:20 PM PDT Using cryo-electron microscopy, scientists have made a breakthrough in our understanding of how our molecular machinery finds the right DNA to copy for making proteins, showing with unprecedented detail the role of a powerhouse transcription factor known as TFIID.

Brain stimulation may reduce symptoms, improve decision-making in people with anorexia Posted: 23 Mar 2016 12:20 PM PDT Core symptoms of anorexia nervosa, including the urge to restrict food intake and feeling fat, are reduced after just one session of a noninvasive brain stimulation technique, according new research.

Breakthrough in diagnosis of melanoma skin cancer Posted: 23 Mar 2016 12:18 PM PDT Researchers have revealed a remarkable link between malignant melanoma and a non-coding RNA gene called SAMMSON. The SAMMSON gene is expressed in human malignant melanoma and, strikingly, the growth of aggressive skin cancer is highly dependent on this gene. The conclusions could pave the way for improved diagnostic tools and skin cancer treatment.

Prooxidants may fix metabolic defect in arthritis-driving T cells Posted: 23 Mar 2016 12:18 PM PDT Researchers have uncovered a metabolic defect that spurs T cells to go rogue in rheumatoid arthritis patients.

Seizure drug Gabapentin lowers postoperative nausea and vomiting risk Posted: 23 Mar 2016 11:28 AM PDT The anticonvulsant medication gabapentin—already a useful part of strategies to control pain after surgery—also effectively reduces the common complication of postoperative nausea and vomiting (PONV), reports a study.

Teen dating violence prevention programs fall short Posted: 23 Mar 2016 11:24 AM PDT While teen dating violence prevention programs increased knowledge and changed student attitudes to be less supportive of such behavior, they did not actually reduce dating violence, according to this meta-analysis of research on middle- and high school intervention programs, report investigators.

People with rage disorder twice as likely to have latent toxoplasmosis parasite infection Posted: 23 Mar 2016 11:23 AM PDT Individuals with a psychiatric disorder involving recurrent bouts of extreme, impulsive anger -- road rage, for example -- are more than twice as likely to have been exposed to a common parasite than healthy individuals with no psychiatric diagnosis. In a study involving 358 adult subjects, researchers found that toxoplasmosis, a relatively harmless parasitic infection carried by an estimated 30 percent of all humans, is associated with intermittent explosive disorder and increased aggression.

DNA molecules directly interact with each other based on sequence, study finds Posted: 23 Mar 2016 08:59 AM PDT Proteins play a large role in DNA regulation, but a new study finds that DNA molecules directly interact with one another in a way that's dependent on the sequence of the DNA and epigenetic factors. This could have implications for how DNA is organized in the cell and even how genes are regulated in different cell types, the researchers say.

Children with cardiomyopathy benefit from treating entire family, new study suggests Posted: 23 Mar 2016 08:59 AM PDT New research shows how more severe cases of pediatric cardiomyopathy-linked heart disease are associated with reduced 'quality of life and functional status,' which can have a negative impact on families of the patients and thus contribute to poor outcomes.

Merits of fish oil supplements examined Posted: 23 Mar 2016 08:59 AM PDT The effects of fish oil supplements on muscle growth has been investigated by a team of academics, revealing the tablets do not give gym-goers an advantage in the weight room.

Paradigm shift: 'We need to study lumps of bacteria' Posted: 23 Mar 2016 08:59 AM PDT New research reveals that bacteria which agglutinate before entering the body are far more resistant than single-celled bacteria. This may be the cause of chronic infections, say scientists.

Savage world for frogs: Biologist discovers clues about frog deaths Posted: 23 Mar 2016 08:56 AM PDT A researcher is obsessed with frogs and figuring out why they are dying at an unprecedented rate around the world. Her latest research suggests that natural selection as well as other evolutionary forces have shaped the evolution of immune genes in lowland leopard frog populations helping them survive a deadly fungus that's killing off many other species worldwide.

Treating withdrawal symptoms could help cannabis users quit, study finds Posted: 23 Mar 2016 08:56 AM PDT Treating symptoms of cannabis withdrawal could help heavy users stay clean longer, finds a new study. Marijuana's long half-life and users' reports of primarily psychological withdrawal symptoms have fueled the longstanding controversy among clinicians and researchers about whether physiological dependency and withdrawal symptoms actually occur.

Brad Pitt's and fruit flies' cowlicks controlled by cancer protein Posted: 23 Mar 2016 08:55 AM PDT What does Brad Pitt have in common with a fruit fly? His Hollywood hairstyles cover a prominent cowlick -- the swirl of hair that that is caused by a patterning mechanism also active in our two-winged friends -- that similarly feature 'polarized' hair patterns.

Survey finds positive view towards living kidney donation Posted: 23 Mar 2016 08:54 AM PDT Researchers examined the willingness of voting US citizens to become living kidney donors and to determine the potential influence of compensation for donation.

Cellular 'light switch' analyzed using neutron scattering Posted: 23 Mar 2016 07:32 AM PDT The internal movements of proteins can be important for their functionality; researchers are discovering more and more examples of this. Now, with the aid of neutron spectroscopy, dynamic processes have also been detected in so-called "LOV photoreceptors". These proteins are widely distributed throughout nature and are of biotechnological relevance. The results highlight the immense potential of neutron scattering experiments for the analysis of cellular processes.

Safety of Whistler sliding track comparable to other tracks Posted: 23 Mar 2016 07:16 AM PDT High speed and athlete inexperience are top contributing factors to injuries and accidents on the Whistler sliding track, according to a new study conducted following the death of an athlete during a training run before the opening ceremonies of the 2010 Vancouver Winter Olympics.

Blurred lines: Human sex chromosome swapping occurs more often than previously thought Posted: 23 Mar 2016 07:16 AM PDT It turns out that the rigid 'line in the sand' over which the human sex chromosomes -- the Y and X -- go to avoid crossing over is a bit blurrier than previously thought. Contrary to the current scientific consensus, new research shows that X and Y DNA swapping may occur much more often.

Identifying threats before they spread Posted: 23 Mar 2016 05:28 AM PDT If an infectious disease outbreak or an attack using an agent such as anthrax were to occur in Chicago, it most likely first will be noticed in emergency rooms throughout the city. Swift identification of the cause of an incoming patients' illness could be crucial to public health and safety personnel being able to intervene in time to save lives, say researchers.

Child alert systems save lives Posted: 23 Mar 2016 05:27 AM PDT Child alert systems for endangered missing and abducted children in Europe can help find them alive, preliminary research has found. The research is the first to examine child alert systems in Europe -- specifically the UK, the Netherlands, Czech Republic and Poland -- which between them issued 19 of the 23 alerts in Europe in 2015.

Scientists offer new insight on rare genetic condition Posted: 23 Mar 2016 05:23 AM PDT All children are screened for a host of conditions at birth, such as Phenylketonuria, a genetic disorder that is passed by mutated genes from both parents to their offspring. Currently the primary way to manage the disease is through a restricted diet. Now, researchers are using magnetic resonance imaging to learn more about the effects of this disorder on the brain and to assist scientists in developing therapeutic drugs.

MEGA evolutionary software re-engineered to handle today's big data demands Posted: 23 Mar 2016 05:22 AM PDT A new version of a popular MEGA (Molecular Evolutionary Genomics Analysis) software has been released, one of the most highly downloaded and widely used tools used by scientists worldwide to harness large-scale DNA sets for comparative studies.

SSRI antidepressants not associated with an increased risk cardiovascular conditions Posted: 23 Mar 2016 05:22 AM PDT Commonly used antidepressants, known as 'selective serotonin reuptake inhibitors', are not associated with an increased risk of cardiovascular conditions, such as heart attacks and strokes, according to new research.

Personality traits can be revealed by how you move Posted: 23 Mar 2016 05:22 AM PDT The ground-breaking study could open up new pathways for health professionals to diagnose and treat mental health conditions in the future.

Should doctors boycott working in Australia's immigration detention centers? Posted: 23 Mar 2016 05:22 AM PDT Two experts debate whether doctors should boycott working in Australia's immigration detention centers. Last month, the president of the Australian Medical Association finally denounced Australia's appalling treatment of asylum seekers, calling it "state-sanctioned child abuse."

Experts urge UK parliament to take action to reduce food waste Posted: 23 Mar 2016 05:22 AM PDT As UK supermarkets pledge to cut food waste by 20 percent within the next decade, experts are calling on the government to take legislative action and debate the Food Waste (Reduction) Bill.

Using frog foam to deliver antibiotics Posted: 23 Mar 2016 05:22 AM PDT Scientists have shown that the foam made by Trinidadian frogs represents a new, non-toxic antibiotic delivery system that may help to prevent infections. Researchers have been analysing the frog foam, showing that it is highly stable and capable of taking up drugs before releasing them at a stable rate.

Adherence to Japanese diet guidelines linked to longer life Posted: 23 Mar 2016 05:20 AM PDT Closer adherence to Japanese dietary guidelines is associated with a lower risk of death from all causes and death from cardiovascular disease, particularly stroke, finds a new study.

Warning: High-intensity training could hurt you if you're not an athlete Posted: 23 Mar 2016 05:20 AM PDT High-intensity 'sprint training' may be gaining popularity at gyms, but if you're new to this form of exercise, the workout could do more harm than good. A study has found signs of stress in the muscle tissues of their non-athlete, untrained subjects after ultra-intense leg and arm cycling exercises. Perhaps more concerning, researchers reported the untrained subjects had a weakened ability to fight off free radicals, molecules that can alter DNA and harm healthy cells.

Decreased blood vessel leakage can improve cancer therapy, reduce tumor spread Posted: 23 Mar 2016 05:20 AM PDT Cancer therapy is often hampered by the accumulation of fluids in and around the tumor, which is caused by leakage from the blood vessels in the tumor. Researchers now show how leakage from blood vessels is regulated. They have identified a novel mechanism whereby leakage can be suppressed to improve the result of chemotherapy and reduce the spread of tumors in mice.

Heavy, persistent pot use linked to economic, social problems at midlife Posted: 23 Mar 2016 05:20 AM PDT People who smoked cannabis four or more days of the week over many years ended up in a lower social class than their parents, with lower-paying, less skilled and less prestigious jobs than those who were not regular cannabis smokers, shows a research study that followed children from birth up to age 38. These regular and persistent users also experienced more financial, work-related and relationship difficulties, which worsened as the number of years of regular cannabis use progressed.

Aging and Alzheimer's: Turning back the clock Posted: 22 Mar 2016 03:21 PM PDT The cell's protein factory may hold key to stalling cognitive decline, say scientists who are investigating how to stop the formation of dystrophic neurites, which are irregularly formed bundles of nerve components prominent in the brains of Alzheimer's patients.

Natural ways to reduce blood sugar for prediabetes/diabetes patients? Posted: 22 Mar 2016 03:21 PM PDT In a new article, a physician discusses whether natural supplements like apple cider vinegar and cinnamon may be used to reduce blood sugar levels in patients with pre-diabetes or diabetes.

More cost-effective cure for hepatitis C may be close Posted: 22 Mar 2016 01:17 PM PDT The cost of treating hepatitis C virus could be cut up to 50 percent if mathematical models are used to predict when patients can safely stop taking direct-acting antiviral medication, according to a new study.

Tetanus shots needed every 30 years, not every 10, say researchers Posted: 22 Mar 2016 10:38 AM PDT Researchers are challenging the convention that tetanus and diphtheria vaccine boosters need to be administered every 10 years. Their paper recommends current adult vaccination schedule should be revisited.

Microsoft's Xbox Kinect breathes new life into respiratory assessment Posted: 22 Mar 2016 09:05 AM PDT Xbox Kinects could be used in the future to assess the health of patients with conditions such as cystic fibrosis. Normally found in the hands of gamers rather than medics, the Microsoft sensors could be used to assess the respiratory function of patients.
