| Posted: 24 Nov 2015 02:03 PM PST Endurance exercise accelerates the development of heart problems in individuals with a particular genetic mutation, a new study finds. In mice with a mutated version of desmoplakin, a protein that maintains the heart wall, exercise made the heart walls come apart sooner. The findings offer insight into how to best manage exercise in individuals with the mutation. |
| The myth about l-trypophan in turkey Posted: 24 Nov 2015 11:38 AM PST Turkey itself doesn't make you sleepy after a Thanksgiving meal. What makes you sleepy is eating very large quantities of turkey, stuffing, potatoes and pie. Turkey does contain tryptophan, but so do yogurt, eggs, fish, cheese and other meats. |
| Posted: 24 Nov 2015 11:35 AM PST A metal-free process has been developed for the rapid synthesis of elusive small-molecule catalysts that promise to speed the making of novel chemicals, including drugs. |
| Fat cells originating from bone marrow found in humans Posted: 24 Nov 2015 11:35 AM PST Fat cells produced by stem cells from the bone marrow may be linked to chronic illnesses like diabetes, cardiovascular disease, kidney disease and some cancers, researchers report. |
| Investigational drug may prevent life-threatening muscle loss in advanced cancers Posted: 24 Nov 2015 11:33 AM PST New data describes how an experimental drug can stop life-threatening muscle wasting (cachexia) associated with advanced cancers and restore muscle health. The experimental agent, known as AR-42 while in testing, was tested in preclinical studies. |
| Immune-disorder treatment in mice holds potential for multiple sclerosis patients Posted: 24 Nov 2015 11:33 AM PST A simple, rapid way to treat an immune-related disorder in mice has been identified by researchers, an approach that could eventually help multiple sclerosis patients after further research. |
| Cataract surgery lessens patients' dizziness Posted: 24 Nov 2015 11:33 AM PST Older people with visual impairment can report feeling dizzy and falling. A new study found that after routine cataract surgery, the improved vision led to patients experiencing significantly less dizziness, although they did not experience fewer falls. |
| Gut microbes signal to the brain when they're full Posted: 24 Nov 2015 11:33 AM PST Don't have room for dessert? The bacteria in your gut may be telling you something. Twenty minutes after a meal, gut microbes produce proteins that can suppress food intake in animals, reports a study. The researchers also show how these proteins injected into mice and rats act on the brain reducing appetite, suggesting that gut bacteria may help control when and how much we eat. |
| Genetic risk for hyperinflammatory disorder from viral infection identified Posted: 24 Nov 2015 08:28 AM PST A group of people with fatal H1N1 flu died after their viral infections triggered a deadly hyperinflammatory disorder in susceptible individuals with gene mutations linked to the overactive immune response, according to a study. Researchers suggest people with other types of infections and identical gene mutations also may be prone to the disorder, known as reactive HLH (rHLH), or hemophagocytic lymphohistiocytosis. |
| Scientists 'see' detailed make-up of deadly toxin for the first time Posted: 24 Nov 2015 08:21 AM PST An exciting advance provides hope for developing novel potential method of treating pneumococcal diseases such as bacterial pneumonia, meningitis and septicaemia. A team of researchers uses a technique called X-ray crystallography to see the individual atoms of the toxin. World Health Organization (WHO) estimated that more than 1.6 million people every year die from pneumococcal infections, including more than 800,000 children under 5 years old. |
| Stored fat fights against the body's attempts to lose weight Posted: 24 Nov 2015 08:21 AM PST The fatter we are, the more our body appears to produce a protein that inhibits our ability to burn fat, suggests new research. The findings may have implications for the treatment of obesity and other metabolic diseases. |
| Mental health risk for new dads Posted: 24 Nov 2015 08:21 AM PST Anxiety around the arrival of a new baby is just as common as postnatal depression, and the risks for men are nearly as high as for women, researchers have found. A mental health researcher reviewed 43 separate studies and found anxiety before and after a child arrives is just as prevalent as depression, affecting around 1 in 10 men, around half the rate for women. |
| Posted: 24 Nov 2015 05:22 AM PST Nerve cells cover their high energy demand with glucose and lactate, scientists confirm. They show for the first time in the intact mouse brain evidence for an exchange of lactate between different brain cells. With this study they were able to confirm a 20-year old hypothesis. |
| Cooking with chloraminated water and salt could create toxic molecules Posted: 24 Nov 2015 05:19 AM PST Several new molecules have been discovered by researchers, who suggest ways to avoid their formation. They have found that cooking with chloraminated water could put potentially harmful toxins in your food. The study reveals several molecules that are almost completely new to researchers, created by cooking with chloraminated tap water and iodized table salt. |
| Infants under 12 months most at risk of physical abuse Posted: 24 Nov 2015 05:19 AM PST Infants under the age of 12 months are most at risk of serious physical abuse, reveals a large study of severely injured children. Compared with children whose injuries had been accidental, the injuries of abused children were more severe and tended to involve the head/brain. |
| Increase in infant deaths attributed to crib bumpers, study suggests Posted: 24 Nov 2015 05:15 AM PST The number of infant deaths and injuries attributed to crib bumpers has spiked significantly in recent years, prompting researchers to call for a nationwide ban on the bedding accessory. The findings stem from an analysis by longtime experts on the topic. |
| Food odors activate impulse area of the brain in obese children Posted: 24 Nov 2015 05:15 AM PST The area of the brain associated with impulsivity and the development of obsessive-compulsive disorder is activated in obese children when introduced to food smells, according to new research. |
| Scientists create genetically modified malaria-blocking mosquitoes Posted: 23 Nov 2015 06:02 PM PST Using a groundbreaking gene editing technique, scientists have created a strain of mosquitoes capable of rapidly introducing malaria-blocking genes into a mosquito population through its progeny, ultimately eliminating the insects' ability to transmit the disease to humans. This new model represents a notable advance in the effort to establish an antimalarial mosquito population, which with further development could help eradicate a disease that sickens millions worldwide each year. |
| How the introduction of farming changed the human genome Posted: 23 Nov 2015 05:26 PM PST Genomic analysis of ancient human remains identifies specific genes that changed during and after the transition in Europe from hunting and gathering to farming about 8,500 years ago. Many of the genes are associated with height, immunity, lactose digestion, light skin pigmentation, blue eye color and celiac disease risk. |
| Ancient viral molecules essential for human development Posted: 23 Nov 2015 05:25 PM PST Genetic material from ancient viral infections is critical to human development, according to researchers. |
| Law experts propose revisions for international health regulations Posted: 23 Nov 2015 07:21 AM PST A trio of global health law experts warn the window for fundamental reform of the International Health Regulations -- opened by the Ebola epidemic -- is 'rapidly closing.' |
| Independent panel of global experts calls for critical reforms to prevent future pandemics Posted: 23 Nov 2015 07:20 AM PST A hard-hitting analysis of the global response to the 2014-15 Ebola outbreak in West Africa has been issued by an independent group of 20 experts from around the globe. |
| Major fall in diabetes-related amputations since the 1990s Posted: 23 Nov 2015 07:20 AM PST A significant reduction in diabetes-related amputations since the mid-1990s has been identified by a new study. Researchers credit this decline to improvements in diabetes care over this period. |
