Urine test can indicate presence of venous thromboembolism in patients at risks for clots

A new study by researchers from California and Canada indicates a simple urine test can indicate the presence of venous thromboembolism, a blood clot that has broken free from its point of origin and which travels through the bloodstream, eventually lodging in a vein.

Competition has subtle effects for male fruit flies

A University of Liverpool study of fruit flies has revealed that males forced to compete with other males become less attractive to females and die young.

Supplemental vitamin C taken by pregnant smokers improves measures of lung function for newborns

Supplemental vitamin C taken by pregnant smokers improved measures of lung function for newborns and decreased the incidence of wheezing for infants through 1 year, according to a study published by JAMA.

Bacteria in urine may be associated with overactive bladder

Contrary to popular belief, urine is not sterile and the bacteria in it may be associated with overactive bladder (OAB) in some women, according to research presented today at the annual meeting of the American Society for Microbiology.

Chronic bystander viral impairs development of memory T cells

Studies of vaccine programs in the developing world have revealed that individuals with chronic infections such as malaria and hepatitis tend to be less likely to develop the fullest possible immunity benefits from vaccines for unrelated illnesses.

New potential treatment for paraplegic patients

People with severe injuries to their spinal cord currently have no prospect of recovery and remain confined to their wheelchairs. Now, all that could change with a new treatment that stimulates the spinal cord using electric impulses.

Scientists reveal how and why immune system's B cells respond only to true threats

The immune system's B cells protect us from disease by producing antibodies, or "smart bullets," that specifically target invaders such as pathogens and viruses while leaving harmless molecules alone.

Researchers examine how basic biology of aging drives chronic disease

A new collection of articles appearing in The Journals of Gerontology, Series A: Biological Sciences and Medical Sciences examine how the basic biology of aging drives chronic disease.

Young adults who smoke water pipes have elevated levels of tobacco-related cancer-causing agents

Young adults who smoked water pipes in hookah bars had elevated levels of nicotine, cotinine, tobacco-related cancer-causing agents, and volatile organic compounds (VOC) in their urine, and this may increase their risk for cancer and other chronic diseases, according to a study published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.

Nanogel heals burn wounds faster

Researchers at the Institute of Bioengineering and Nanotechnology have developed a nanogel that can accelerate the healing of burn wounds to minimize the risk of infection and scarring. The technology is based on IBN’s proprietary self-assembling ultrashort peptide technology, which are short sequences of amino acids.

Shark antibodies reveal evolutionary principles of immunoglobulins

Custom-tailored antibodies are regarded as promising weapons against a multitude of serious illnesses. Since they can accurately recognize specific structures on the surface of viruses, bacteria or cancer cells, they are already being deployed successfully in cancer diagnostics and therapy, as well as against numerous other diseases. The stability of the sensitive antibodies is a decisive factor in every step, from production and storage to therapeutic application.

Researchers identify certain neurons responsible for behavioral decisions in rats

A new paper published by OIST's Neurobiology Research Unit identifies some of the neurons responsible for behavioral decisions in rats. Using a technique that employs light to control nerve cell activity, researchers in Professor Jeff Wickens' Unit inactivated a region of the brain and showed that it caused the rats to behave more flexibly while trying to get a reward.

Scientists develop new way to decode specific aspects of movement in human brain

Our human brains are filled with maps: visual maps of our external environments, and motor maps that define how we interact physically within those environments. Somehow these separate points of reference need to correspond with - and to - one another in order for us to act, whether it's grasping a coffee cup or hitting a tennis ball.

Suppressing hyperactivity of calcium channels alleviates familial Alzheimer's disease

In 2008, researchers at the Perelman School of Medicine at the University of Pennsylvania showed that mutations in two proteins associated with familial Alzheimer's disease (FAD) disrupt the flow of calcium ions within neurons.

Cryogenically-cooled technology significantly enhances current capabilities of cardiac and brain MRI in mice

To effectively study cardiac morphology and function, or follow neuroinflammatory processes in the brain, image quality is everything. The current capabilities of cardiac and brain MRI in mice are being significantly enhanced by cryogenically-cooled technology, which is proving invaluable to researchers around the world.
