Environmental factors may trigger lupus onset and progression

23/11/2017

While genetics play a role in the development of Lupus, a systemic autoimmune disease that can attack any organ system in the human body, so do environmental triggers, such as particulates in air pollution and ultraviolet light, explains Gaurav Gulati, MD, a physician-researcher at the University of Cincinnati (UC) College of Medicine.

Biomarker may predict early Alzheimer's disease

22/11/2017

Researchers at Sanford Burnham Prebys Medical Discovery Institute (SBP) have identified a peptide that could lead to the early detection of Alzheimer's disease (AD). The discovery, published in Nature Communications, may also provide a means of homing drugs to diseased areas of the brain to treat AD, Parkinson's disease, as well as glioblastoma, brain injuries and stroke.

Dog ownership linked to lower mortality

21/11/2017

A team of Swedish scientists have used national registries of more than 3.4 million Swedes aged 40 to 80 to study the association between dog ownership and cardiovascular health. Their study shows that dog owners had a lower risk of death due to cardiovascular disease or to other causes during the 12-year follow-up.

Understanding the Berlin patient's unexpected cure

20/11/2017

A decade ago, the medical world was shocked when a patient in Berlin, Germany, had been declared free of HIV after receiving a stem cell transplant to treat cancer. Doctors have repeatedly tried to replicate the result, but this HIV cure has evaded other patients so far.

Could this protein protect people against coronary artery disease?

20/11/2017

The buildup of plaque in the heart's arteries is an unfortunate part of aging. But by studying the genetic makeup of people who maintain clear arteries into old age, researchers led by UNC's Jonathan Schisler, PhD, have identified a possible genetic basis for coronary artery disease (CAD), as well as potential new opportunities to prevent it.

New software enables early diagnosis of arteriosclerosis

17/11/2017

Little exercise, fatty food and too many cigarettes – factors like these aid the onset of arterial calcification, also known as arteriosclerosis. Doctors are typically only able to diagnose the disease once it reaches an advanced stage. Computer scientists at the University of Kaiserslautern are developing a software program that will allow doctors to detect calcification earlier.
