| Arctic warming linked to fewer European and US cold weather extremes, new study shows Posted: 15 Jun 2014 11:38 AM PDT Climate change is unlikely to lead to more days of extreme cold, similar to those that gripped the USA in a deep freeze last winter, new research has shown. The Arctic amplification phenomenon refers to the faster rate of warming in the Arctic compared to places further south. It is this phenomenon that has been linked to a spike in the number of severe cold spells experienced in recent years over Europe and North America.  |
| Posted: 15 Jun 2014 11:38 AM PDT Researchers have found evidence of widespread refreezing of ice at the bottom of the Greenland Ice Sheet; some of these features coincide with faster flows. The newly revealed forms may help scientists understand more about how ice sheets behave and how they will respond to a warming climate.  |
| Diabetes risk: Understanding the unique nature of children's bodies and brains Posted: 15 Jun 2014 11:38 AM PDT With the increase in childhood obesity and the associated increase in type 2 diabetes among children and adolescents, there is growing interest in how children's bodies process the foods they eat and how obesity and diabetes begin to develop at early ages.  |
| Posted: 15 Jun 2014 11:36 AM PDT Researchers have deduced essential biological and genetic information from the genome sequence of the whipworm, an intestinal parasitic worm that infects hundreds of millions of people in developing countries. This information acts as the foundation for the development of new strategies and treatments against this debilitating parasite.  |
| BRCA test results affect patients' breast cancer surgery plans Posted: 13 Jun 2014 07:17 AM PDT Seven in 10 women with breast cancer who learned before surgery they have BRCA gene mutations changed their surgical plan, often to a more extensive procedure that would reduce future cancer risk, researchers have found. The authors therefore recommend that women who meet genetic testing guidelines get the tests before surgery.  |
| Opioid use prior to spine surgery linked to diminished patient reported outcomes Posted: 12 Jun 2014 11:23 AM PDT The use of opioid pain relievers (prescription medications, such as Percocet) have been linked to less improvement and higher levels of dissatisfaction following spine surgery, a study finds. "We have demonstrated that increasing amounts of preoperative opioid consumption may have a harmful effect on patient reported outcomes in those undergoing spinal surgery," said study's lead author.  |
| Testing Parkinson's disease immune-based drugs: New models Posted: 12 Jun 2014 10:23 AM PDT Using powerful, newly developed cell culture and mouse models of sporadic Parkinson's disease (PD), researchers have demonstrated that immunotherapy with specifically targeted antibodies may block the development and spread of PD pathology in the brain. By intercepting the distorted and misfolded alpha-synuclein (α-syn) proteins that enter and propagate in neurons, creating aggregates, the researchers prevented the development of pathology and also reversed some of the effects of already-existing disease.  |
| African Americans respond better to first-line diabetes drug than whites Posted: 12 Jun 2014 10:23 AM PDT African Americans taking the diabetes drug metformin saw greater improvements in their blood sugar control than white individuals who were prescribed the same medication, according to a new study. Metformin is the most common oral medication prescribed for diabetes. It decreases the amount of glucose produced by the liver and helps the body respond better to insulin, the hormone that helps carry sugar from the bloodstream into cells.  |
| Heart rate variability may predict risk of disease in premature infants Posted: 12 Jun 2014 08:46 AM PDT Measuring variability of heart rate may identify premature infants at risk of developing necrotizing enterocolitis, a serious inflammatory condition that can lead to death, according to researchers. Necrotizing enterocolitis, or NEC, may lead to destruction of the intestinal wall and vital organ failure. It affects 6 to 10 percent of premature infants within the first two weeks of life.  |
| Standing up gets groups more fired up for team work Posted: 12 Jun 2014 08:46 AM PDT Chairs provide great support during long meetings, but they may also be holding us back. Standing during meetings boosts the excitement around creative group processes and reduces people's tendency to defend their turf, according to a new study. The participants wore small sensors around their wrists to measure "physiological arousal" -- the way people's bodies react when they get excited. When a person's arousal system becomes activated, sweat glands around the feet and hands release bursts of moisture. The sensors pass a small current of electricity through the skin to measure these moisture bursts.  |
| Blood product sterilization taken too far? Posted: 12 Jun 2014 07:49 AM PDT Certain processes used to sterilize blood products could potentially cause serious health issues in transfusion recipients, according to an international study. These processes purportedly alter the blood platelets to the extent of preventing them from carrying out their functions correctly and may be the cause of hemorrhages observed in patients having received treated blood.  |

| Reversal of type 1 diabetes in mice may eventually help humans Posted: 14 Jun 2014 04:26 PM PDT Investigators have found a therapy that reverses new onset type 1 diabetes in mouse models and may advance efforts in combating the disease among humans. There is no cure for Type 1 diabetes though it can be controlled with insulin therapy. Symptoms of the disease include frequent urination, excessive thirst and weight loss even though you are eating more.  |
| Canola oil may be an oil of choice for people with type 2 diabetes Posted: 14 Jun 2014 12:03 PM PDT New research suggests canola oil may be one of the oils of choice for people with Type 2 diabetes. Researchers compared people with Type 2 diabetes who ate either a low glycemic index diet that included bread made with canola oil, or a whole wheat diet known to reduce the risk of cardiovascular disease. The research found that those on the canola bread diet experienced both a reduction in blood glucose levels and a significant reduction in LDL, or "bad," cholesterol.  |
| Improving diet quality reduces risk for type 2 diabetes Posted: 14 Jun 2014 12:03 PM PDT Improving the overall quality of one's diet helps to prevent type 2 diabetes, independent of other lifestyle changes, according to a new study. The study found that those who improved their diet quality index scores by 10 percent over four years -- by eating more whole grains, fruits and vegetables, and less sweetened beverages and saturated fats, for example -- reduced their risk for type 2 diabetes by about 20 percent, compared to those who made no changes to their diets.  |
| Posted: 14 Jun 2014 12:01 PM PDT For prediabetics, many interventions focus on lifestyle changes and weight loss, but new research on periodic fasting has identified a biological process in the body that converts bad cholesterol in fat cells to energy, thus combating diabetes risk factors.  |
| Testing Parkinson's disease immune-based drugs: New models Posted: 12 Jun 2014 10:23 AM PDT Using powerful, newly developed cell culture and mouse models of sporadic Parkinson's disease (PD), researchers have demonstrated that immunotherapy with specifically targeted antibodies may block the development and spread of PD pathology in the brain. By intercepting the distorted and misfolded alpha-synuclein (α-syn) proteins that enter and propagate in neurons, creating aggregates, the researchers prevented the development of pathology and also reversed some of the effects of already-existing disease.  |
| Low cholesterol linked with worse survival in patients with kidney cancer Posted: 12 Jun 2014 05:57 AM PDT People are often told to reduce their cholesterol to improve their heart health, but new research suggests that low cholesterol may increase kidney cancer patients' risk of dying from their disease. The findings indicate that cholesterol testing may help doctors as they monitor and treat patients with kidney cancer.  |
| Examining soccer players' productivity Posted: 12 Jun 2014 05:51 AM PDT The productivity of top goal
scorers in international football (soccer) is under study as FIFA World Cup gets underway. The researchers applied advanced econometric techniques to a sample of 66
top goal scorers in the Union of European Football Associations (UEFA)
Champions League between 1991 and 2011.  |
| 6,000 steps a day keeps knee OA limitations away Posted: 12 Jun 2014 05:51 AM PDT Walking reduces risk of functional limitation associated with knee osteoarthritis (OA), new research shows. In fact, the study suggests that walking 6,000 or more steps per day may protect those with or at risk of knee of OA from developing mobility issues, such as difficulty getting up from a chair and climbing stairs.  |
| Posted: 12 Jun 2014 05:50 AM PDT Obesity and obstructive sleep apnea (OSA) tend to co-exist and are associated with a variety of cardiovascular risk factors, including inflammation, insulin resistance, abnormal cholesterol, and high blood pressure. While effective therapies are available for OSA, researchers are still unclear about what interventions are most effective in reducing the burden of risk factors for cardiovascular disease associated with OSA in obese patients.  |
| Cancer drug boosts levels of vascular-protective gene, KLF2 Posted: 12 Jun 2014 05:50 AM PDT An existing drug, bortezomib (Velcade), has been shown to help prevent clot development, new research shows. In 2008, the Food and Drug Administration approved bortezomib (Velcade) to treat multiple myeloma, which is a type of bone cancer and mantle cell lymphoma -- a particularly aggressive form of non-Hodgkin lymphoma. In addition to attacking cancer cells, the drug has been shown to help prevent clot development common to many forms of the disease.  |
