Excess activation of LOX may play causative role in progression of cardiac failure

Heart failure is a progressive condition, where structural and functional alterations of the ventricle limit the ability of the heart to either fill or eject blood. There are approximately 550,000 new cases of heart failure each year with a prevalence of nearly 5 million; most patients die within five years of diagnosis.

New study raises possibility of therapeutic intervention for brain blood vessel disease

Cerebral cavernous malformations (CCM) are the most common cause of stroke in young people. These malformations also known as Cavernomas are present in 0.1-0.5% of the population, with about 60% causing symptoms. Currently there is no drug treatment available for CCM.

German scientists use DNA molecules to make nanoscale component

In order for a machine to perform work, it needs parts that move relative to each other. This also holds true for nanoscale machines. German scientists have now used DNA molecules to make a nanoscale component that makes it possible for two individual parts to move relative to each other. As reported in the journal Angewandte Chemie, this component could be used as a molecular guide bearing and may form the basis for more complex systems.

Study may help identify unborn children at higher risk for birth defects

Researchers at the University of Toronto have discovered a novel function performed by the breast cancer 1 protein (BRCA1), which regulates DNA repair. Well known for the role it plays in breast and ovarian cancer, this study revealed that the BRCA1 protein actually plays a much broader biological role, particularly in protecting the developing embryo from the damaging effects of reactive oxygen species (ROS).

Purdue University-led researchers determine structure of Zika virus

A team led by Purdue University researchers is the first to determine the structure of the Zika virus, which reveals insights critical to the development of effective antiviral treatments and vaccines.

Body temperature can have profound impact on diabetic patients

The World Health Organization estimates that of the 500 million people worldwide thought to have diabetes, 90% have type 2 diabetes and the number diagnosed with diabetes by 2020 will increase dramatically.

Over a third of people in UK and US will be obese by 2025

A recent analysis of body mass index (BMI) around the world has revealed a startling increase in the prevalence of obesity. The number of obese people worldwide increased from 105 million in 1975 to 641 million in 2014.

New UCLA study reveals how the brain combines sound and vision

A new UCLA psychology study provides insights into how the brain combines sound and vision. The research suggests that there is not one sole mechanism in the brain that governs how much our senses work together to process information.

New technologies go far beyond traditional use of contact lenses for vision correction

Imagine contact lenses that can deliver medicines directly to the eye, slow progression of nearsightedness in children, or monitor glucose levels in patients with diabetes.

Researchers apply robust parameter selection, verification techniques to dynamic HIV model

Physical and biological models often have hundreds of inputs, many of which may have a negligible effect on a model's response. Establishing parameters that can be fixed at nominal values without significantly affecting model outputs is often challenging; sometimes these parameters cannot be simply discerned by the outputs.

Study links voluntary exercise during pregnancy to more physically active children

Baylor College of Medicine researchers have discovered that female mice that voluntarily exercise during pregnancy have offspring that are more physically active as adults. The research appears in The FASEB Journal.

Aging reduces axonal regeneration after spinal cord injury

Older Americans are increasingly active, and this lifestyle shift has contributed to the rise in average age of a person experiencing a spinal cord injury. The changing demographic calls for a better understanding of how aging impacts recovery and repair after a spinal cord injury.

Tumor suppressor p53 gene twice as likely to be defective in autistic children

A large study by researchers with the UC Davis MIND Institute has found that a gene whose role is to suppress cellular damage from environmental stressors is nearly twice as likely to be defective in children with autism spectrum disorder (ASD), and that the deficit is also present in their fathers.

Symptom Tracking App for Concussions helps athletes, parents deal with head injuries

Thirteen-year-old Madeline Yunker fell hard during a soccer match three years ago, striking her head on the turf with enough force to cause a concussion.

Prevalence of autism spectrum disorder in U.S. unchanged, finds new CDC report

Researchers at the Johns Hopkins Bloomberg School of Public Health contributed to a new U.S. Centers for Disease Control and Prevention (CDC) report that finds the prevalence of autism spectrum disorder (ASD) largely unchanged from two years ago, at one in 68 children (or 1.46 percent).

Experimental urine test identifies 92% of men with elevated PSA levels

An experimental urine test that detects genetic changes associated with prostate cancer identified 92 percent of men with elevated PSA (prostate-specific antigen) levels who had high-grade cancers, according to a study published today in JAMA Oncology online.

Study points to possible new genetic risk factor for celiac disease

Researchers have identified a common variant in a non-coding RNA that may contribute to the intestinal inflammation that occurs in people with celiac disease. The findings point to a possible new risk factor for developing celiac disease in people with celiac disease risk genes.

School Breakfast Program in NYC boosts student participation

Serving free breakfast in New York City's classrooms has boosted the number of students eating what some consider the most important meal of the day at school, according to research by New York University's Institute for Education and Social Policy and the Center for Policy Research at Syracuse University's Maxwell School of Citizenship and Public Affairs.

Rheumatoid arthritis patients who stop smoking reduce their risk of earlier death

University of Manchester-led research has found new evidence to suggest that, not only is smoking associated with earlier deaths in those with rheumatoid arthritis, but also those who stop smoking dramatically reduce their risk of earlier death, as published in Arthritis Care and Research journal.

Commonly used fungicides could cause gene expression changes in brain cells

Scientists at the UNC School of Medicine have found a class of commonly used fungicides that produce gene expression changes similar to those in people with autism and neurodegenerative conditions, including Alzheimer's disease and Huntington's disease.
