A new Rutgers study is giving hope to older men concerned about the effects of cholesterol-lowering medications on their sexual health. The research, conducted at Rutgers Robert Wood Johnson Medical School, found that statin medication prescribed to lower cholesterol and decrease the chance of heart attack and stroke, also improves a man's erectile function. The researchers reported their findings at the American College of Cardiology's annual scientific session in Washington DC March 29 and in the April issue of The Journal of Sexual Medicine. "Older men who have poor ...

Heart valve defects are a common cause of death in newborns. Scientists at the University of Bonn and the caesar research center have discovered "Creld1" is a key gene for the development of heart valves in mice. The researchers were able to show that a similar Creld1 gene found in humans functions via the same signaling pathway as in the mouse. This discovery is an important step forward in the molecular understanding of the pathogenesis of heart valve defects. The findings have been published in the journal "Developmental Cell". Atrioventricular septal defect (AVSD) ...

Data from satellite sensors show that during the Northern Hemisphere's growing season, the Midwest region of the United States boasts more photosynthetic activity than any other spot on Earth, according to NASA and university scientists. Healthy plants convert light to energy via photosynthesis, but chlorophyll also emits a fraction of absorbed light as fluorescent glow that is invisible to the naked eye. The magnitude of the glow is an excellent indicator of the amount of photosynthesis, or gross productivity, of plants in a given region. Research in 2013 led by Joanna ...

TORONTO, ON, March 31, 2014 -- Improving hand hygiene compliance by healthcare professionals is no easy task, but a first-of-its-kind Canadian study by researchers at Women's College Hospital shows simply asking patients to audit their healthcare professional is yielding high marks. The study, published in the April edition of the American Journal of Infection Control, details the findings of an 11-month pilot project looking at an alternative method of hand hygiene auditing using the patient-as-observer approach. In this method, patients observe and record hand hygiene ...

Researchers at Western University (London, Canada) have found youth living in rural areas are more likely to sustain concussions from injuries involving motorized vehicles such as all-terrain vehicles and dirt bikes, whereas youth living in urban areas suffer concussions mostly as a result of sports. Hockey accounts for 40 per cent of those injuries. The study which reveals where and how children are receiving concussions is published in the Journal of Trauma and Acute Care Surgery. Dr. Doug Fraser, a scientist with the Children's Health Research Institute at Lawson ...

CORVALLIS, Ore. – Researchers at Oregon State University have discovered novel proteins in, or on the surface of the bacteria that causes gonorrhea, which offer a promising new avenue of attack against a venereal disease that is showing increased resistance to the antibiotics used to treat it. Only a single, third-generation cephalosporin antibiotic still shows good efficacy against gonorrhea, creating a race against time to find some alternative way to treat this disease that can have serious health effects. It's the second most commonly reported infectious disease in ...

RIVERSIDE, Calif. — Do you want information on Viagra or ibuprofen? Check out general social networks such as Twitter and Pinterest. Interested in sleep disorders or depression?

Previously a postdoctoral fellow at University College London (UCL), he has extensive research experience, ...

While patients diagnosed with bladder cancer usually face a favorable prognosis, many experience recurrence after treatment. Because frequent, painful screenings are needed to identify recurrences, the ablility to identify patients at high risk of recurrent cancer could help to improve quality of life for all bladder cancer patients. A new study published in BJU International, "Genetic polymorphisms modify bladder cancer recurrence and survival in a U.S. population-based prognostic study," suggests that certain inherited DNA sequences may affect a bladder cancer patient's ...

WASHINGTON (March 31, 2014) — In a comparison of two blood-thinning medications, heparin was associated with significantly fewer major cardiovascular events at 28 days than bivalirudin in patients receiving primary percutaneous coronary intervention after a heart attack, according to research presented at the American College of Cardiology's 63rd Annual Scientific Session. The single-center, open label trial enrolled 1,829 patients with suspected heart attack who received a coronary angiography, an imaging test to see how blood flows through the heart. Patients were randomized ...

Anti-anxiety drugs and sleeping pills have been linked to an increased risk of death, according to new research from the University of Warwick. The large study, published in BMJ, shows that several anxiolytic (anti-anxiety) drugs or hypnotic drugs (sleeping pills) are associated with a doubling in the risk of mortality. Although these findings are based on routine data and need to be interpreted cautiously, the researchers recommended that a greater understanding of their impact is essential. Professor Scott Weich, Professor of Psychiatry at the University of ...

WASHINGTON (March 31, 2014) — Use of drug-eluting stents is associated with a lower risk of major cardiovascular events at one year compared to bare metal stents when followed by an individualized course of blood-thinning medication among patients previously thought to be uncertain candidates for drug-eluting stents due to their heightened risk of bleeding or blood clots, according to research presented at the American College of Cardiology's 63rd Annual Scientific Session. Positive study findings for patients receiving a shorter than currently recommended course of ...

This news release is available in German. Objects with sizes in the nanometer range, such as the molecular building blocks of living cells or nanotechnological devices, are continuously exposed to random collisions with surrounding molecules. In such fluctuating environments the fundamental laws of thermodynamics that govern our macroscopic world need to be rewritten. An international team of researchers from Barcelona, Zurich and Vienna found that a nanoparticle trapped with laser light temporarily violates the famous second law of thermodynamics, something that ...

WASHINGTON (March 31, 2014) — Patients with severe ischemic heart disease and heart failure can benefit from a new treatment in which stem cells found in bone marrow are injected directly into the heart muscle, according to research presented at the American College of Cardiology's 63rd Annual Scientific Session. "Our results show that this stem cell treatment is safe and it improves heart function when compared to placebo," said Anders Bruun Mathiasen, M.D., research fellow in the Cardiac Catherization Lab at Rigshospitalet University Hospital Copenhagen, and lead investigator ...

WASHINGTON (March 31, 2014) — The first one-year outcomes data of transcatheter heart valve replacement (TAVR) in nearly all U.S. patients undergoing this procedure shows that real-world outcomes are comparable to or slightly better than those found in clinical trials, according to registry data presented at the American College of Cardiology's 63rd Annual Scientific Session. However, specific baseline characteristics of patients undergoing TAVR are associated with differing degrees of death and survival and may be important considerations for patient counseling and shared ...

A new research discovery published in the April 2014 issue of the Journal of Leukocyte Biology may open the door to new therapies that help treat immune disorders or curb runaway inflammation. Specifically, scientists have discovered a molecule that can induce cell death (apoptosis) in a key type of immune cell (dendritic cells). With this understanding, it may be possible to develop new therapies that essentially shut down dendritic cell activity, and thereby reducing an immune reaction. "We hope that our findings provide better understanding of immune regulation, which ...

The sun emitted a significant solar flare, peaking at 1:48 p.m. EDT March 29, 2014, and NASA's Solar Dynamics Observatory captured images of the event. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel. To see how this event impacted Earth, please visit NOAA's Space Weather Prediction Center at http://spaceweather.gov, the U.S. government's ...

Phillip Koeffler, Senior Principal Investigator at CSI Singapore and Deputy Director of NCIS, has conducted a successful comprehensive genomic study of oesophageal squamous ...

Limiting climate change to 2°C means shutting down coal power plants - an unpopular proposition for coal power companies. But a new study shows that delaying climate policies could prove even worse for power plant owners. Coal power plants are a major source of greenhouse gas emissions, and new plants are planned around the world, particularly in India and China. These new power plants are built to run for 30-50 years, paying off only after years of operation. But stringent climate policies could make the cost of emission so high that coal power generation is no longer ...
