Inhaled Nitric Oxide still being used in preterm neonates despite evidence of short-term benefit

Inhaled Nitric Oxide (iNO) is a drug approved by the Food and Drug Administration that is commonly used in term and near-term neonates who have severe respiratory failure caused by pulmonary hypertension. Over the last decade there have been multiple large studies trying to determine a clinical use for iNO in preterm neonates, but despite evidence of short-term benefit, this drug has not been shown to improve long-term outcomes in preemies.

Salk scientists move one step closer to creating drug that could prevent HIV virus

Imagine a single drug that could prevent human immunodeficiency virus (HIV) infection, treat patients who have already contracted HIV, and even remove all the dormant copies of the virus from those with the more advanced disease. It sounds like science fiction, but Salk scientists have gotten one step closer to creating such a drug by customizing a powerful defense system used by many bacteria and training this scissor-like machinery to recognize the HIV virus.

Study shows that households can serve as reservoir for transmitting MRSA

Households can serve as a reservoir for transmitting methicillin-resistant Staphylococcus aureus (MRSA), according to a study published this week in mBio, the online open-access journal of the American Society for Microbiology. Once the bacteria enters a home, it can linger for years, spreading from person to person and evolving genetically to become unique to that household.

Study finds significant links between depression, poor dietary quality and high BMI

In a study published in the Journal of the Academy of Nutrition and Dietetics, researchers from the RAND Corporation report that for people receiving food assistance there are significant links between depression, poor dietary quality, and high body mass index (BMI).

Neuroscientists reveal how olfaction is encoded in the brain

In a study that helps to deconstruct how olfaction is encoded in the brain, neuroscientists at University of California, San Diego School of Medicine have identified a type of neuron that appears to help tune, amplify and dampen neuronal responses to chemosensory inputs from the nasal cavity.

Finding appears to support the hypothesis that Alzheimer's is an autoimmune disease

Brain levels of the lipid ceramide are high in Alzheimer's disease, and now scientists have found increased levels of an antibody to the lipid in their disease model.

Perceptual learning training can improve contrast sensitivity in older adults

Older adults whose vision is affected by declining contrast sensitivity - which is a factor in the ability to detect and resolve details in low light - can improve their ability to see with perceptual learning training, according to researchers at the University of California, Riverside and Brown University.

Narcolepsy bears trademarks of classic autoimmune disorder

Narcoleptics suffer from bouts of sleepiness and sleep attacks, which impair their ability to function in daily life. But the precise cause of narcolepsy has long eluded scientists, and the cure for the devastating neurological disorder afflicting an estimated three million people worldwide -- and one in 3,000 Americans -- remains at bay.

MedUni Vienna experts recommend regular colonoscopy screening to prevent bowel cancer

Bowel cancer is one of the most common types of cancer. The prognosis depends greatly on the stage at which the tumour is discovered. Colonoscopy is regarded as the best method for identifying pre-cancerous changes. If these changes are treated promptly, the disease can be stopped in its tracks.

Naturally-occurring protein in the brain can curb binge alcohol drinking

A new study led by University of North Carolina School of Medicine researchers has found that a naturally-occurring protein in the brain can act to suppress binge alcohol drinking, a major public health problem estimated to cost the U.S. more than $170 billion each year.

Tourette syndrome patients may face second psychiatric disorder during their lifetimes

A new study of Tourette syndrome (TS) led by researchers from UC San Francisco and Massachusetts General Hospital has found that nearly 86 percent of patients who seek treatment for TS will be diagnosed with a second psychiatric disorder during their lifetimes, and that nearly 58 percent will receive two or more such diagnoses.

Researchers take images of tiny molecular machine that bacteria use to infect host cells

Armed with a microscope capable of zooming in on organisms measured in billionths of a meter, scientists report they are the first to observe one of the tiny molecular machines that bacteria use to infect host cells. Findings appear in the Proceedings of the National Academy of Sciences.

Use of psychedelic drugs linked to less psychological distress, fewer suicidal thoughts

A history of psychedelic drug use is associated with less psychological distress and fewer suicidal thoughts, planning and attempts, according to new research from Johns Hopkins and the University of Alabama at Birmingham.

Researchers use stem cells from sickle cell disease patients to grow mature red blood cells

Researchers at Johns Hopkins have successfully corrected a genetic error in stem cells from patients with sickle cell disease, and then used those cells to grow mature red blood cells, they report. The study represents an important step toward more effectively treating certain patients with sickle cell disease who need frequent blood transfusions and currently have few options.

Hormone therapy does not safeguard post-menopausal women against cardiovascular disease

New evidence published today in the Cochrane Library shows that hormone replacement therapy does not protect post-menopausal women against cardiovascular disease, and may even cause an increased risk of stroke.

People who get easily bored or frustrated are prone to body-focused repetitive behaviors

Individuals who get easily bored, frustrated or impatient are more inclined to develop skin-picking and other body-focused repetitive behaviors, say researchers at the Institut universitaire en santé mentale de Montréal and the University of Montreal.

Scientists find blood-based genomic biomarkers that could help identify young boys with ASD

In a study published in the current online issue of JAMA Psychiatry, an international team of scientists, led by researchers at the University of California, San Diego School of Medicine, report finding a highly accurate blood-based measure that could lead to development of a clinical test for autism spectrum disorder (ASD) risk in males as young as one to two years old.

Advanced clinical decision support tools help reduce mortality for pneumonia patients

A new study by Intermountain Medical Center researchers in Salt Lake City found that using advanced clinical decision support tools reduces mortality for the 1.1 million patients in the Unites States who are treated for pneumonia each year.

Understanding genetic machinery that drives malignant pediatric adrenocortical tumors

In an advance that could lead to better identification of malignant pediatric adrenocortical tumors, and ultimately to better treatment, researchers have mapped the "genomic landscape" of these rare childhood tumors. Their genomic mapping has revealed unprecedented details, not only of the aberrant genetic and chromosomal changes that drive the cancer, but the sequence of those changes that trigger it.

UC Irvine researchers discover inner mechanisms of jet lag

Long the stuff of science fiction, the disembodied "brain in a jar" is providing science fact for UC Irvine researchers, who by studying the whole brains of fruit flies are discovering the inner mechanisms of jet lag.
