Vitamin D replacement improves muscle efficiency Posted: 17 Mar 2013 07:14 PM PDT New research shows for the first time a link between vitamin D levels and muscle efficiency. Vitamin D supplementation may also be effective in improving skeletal muscle function. The findings may explain the physical fatigue commonly experienced by patients with vitamin D deficiency, with broad implications for a large section of society.

White blood cells found to play key role in controlling red blood cell levels Posted: 17 Mar 2013 12:47 PM PDT Researchers have found that macrophages – white blood cells that play a key role in the immune response – also help to both produce and eliminate the body's red blood cells (RBCs). The findings could lead to novel therapies for diseases or conditions in which the red blood cell production is thrown out of balance.

Novel drug delivery system releases drugs in response to compression by the patient's hand Posted: 17 Mar 2013 12:47 PM PDT Medical researchers have succeeded in developing a gel material which is capable of releasing drugs in response to pressure applied by the patient.

New drugs may improve quality of life for people with Parkinson's disease Posted: 14 Mar 2013 02:57 PM PDT Three new studies present possible positive news for people with Parkinson's disease. The studies report on treatments for blood pressure problems, the wearing-off that can occur when people have taken the main drug for Parkinson's for a long time, and for people early in the disease whose symptoms are not well-controlled by their main drugs.

Two-pronged immune cell approach could lead to a universal shot against the flu Posted: 14 Mar 2013 02:56 PM PDT Influenza virus-specific CD8+ T cells or virus-specific non-neutralizing antibodies are each relatively ineffective at conferring protective immunity alone. But, when combined, the virus-specific CD8 T cells and non-neutralizing antibodies cooperatively elicit robust protective immunity.

Smart-bombing cancer, Alzheimer's disease, and more Posted: 14 Mar 2013 11:42 AM PDT Scientists are crafting new pharmaceuticals that could dramatically improve a patient's odds when heavy-duty drugs are prescribed. The research is focused on developing drugs with the kind of precision that the military seeks with smart bombs.

Predicting hotspots for future flu outbreaks Posted: 14 Mar 2013 11:13 AM PDT A major pandemic could occur if bird flu were to become highly contagious among humans. Scientists are making sure we get a leg up on the threat by developing predictions about where outbreaks are most likely to begin.

College kids who don't drink milk could face serious consequences Posted: 14 Mar 2013 11:11 AM PDT College-age kids who don't consume at least three servings of dairy daily are three times more likely to develop metabolic syndrome than those who do, said a new study. "That alarming finding means that three-fourths of the 18- to 25-year-old college applicants surveyed are at risk for metabolic syndrome ," said a professor of food science and human nutrition.

Fungus uses copper detoxification as crafty defense mechanism Posted: 14 Mar 2013 11:11 AM PDT A potentially lethal fungal infection appears to gain virulence by being able to anticipate and disarm a hostile immune attack in the lungs, according to a new article.

Outside the box: Brain aneurysm treatment used to stop irregular heart rhythms Posted: 14 Mar 2013 11:09 AM PDT For the first time, scientists have used a technique normally employed in treating brain aneurysms to treat severe, life-threatening irregular heart rhythms in two patients.

Teen sexting, the gender gap Posted: 14 Mar 2013 09:49 AM PDT A survey of US adolescents reveals a gender gap in attitudes towards sexting and perceived harm.

Pig brain models provide insights into human cognitive development Posted: 14 Mar 2013 09:43 AM PDT A mutual curiosity about patterns of growth and development in pig brains has brought two research groups together. Animal scientists have now developed a model of the pig brain that they plan to use to answer important questions about human brain development.

Will having one lung limit Pope Francis? Posted: 14 Mar 2013 09:41 AM PDT A pulmonologist explains why a person can function normally on one lung.

Cord blood effective alternative to matched donor stem cells for kids with rare disorder Posted: 14 Mar 2013 08:18 AM PDT Transplants of blood-forming stem cells from umbilical cord blood may be an effective alternative to transplants of matched donor bone marrow stem cells to treat children with a rare, debilitating disease known as Hurler's syndrome, according to new results.

Intense terahertz pulses cause DNA damage but also induce DNA repair Posted: 14 Mar 2013 08:18 AM PDT Terahertz radiation, a slice of the electromagnetic spectrum that occupies the middle ground between microwaves and infrared light, is rapidly finding important uses in medical diagnostics, security, and scientific research. As scientists and engineers find evermore practical uses for this form of radiation, questions persist about its potential human health risks.

Problems of pathological gambling differ for younger and older gamblers Posted: 14 Mar 2013 08:06 AM PDT A new study says early intervention is key to successful treatment of gambling. A new study shows that a patient's age influences how severe the psychopathology and clinical aspects of pathological gambling are.

Mutations in VCP gene implicated in a number of neurodegenerative diseases Posted: 13 Mar 2013 06:40 PM PDT New research gives insight into how single mutations in the VCP gene cause a range of neurological conditions including a form of dementia called Inclusion Body Myopathy, Paget's Disease of the Bone and Frontotemporal Dementia (IBMPFD), and the motor neuron disease Amyotrophic Lateral Sclerosis (ALS).
