BOSTON - Poor nutrition and lack of exercise lead to the increasing prevalence of obesity which, in turn, is the major predictor of diabetes and future risk of cardiovascular disease in western societies. Excess weight is also closely associated with obstructive sleep apnea (OSA), the increasingly common and potentially serious sleep disorder that is often marked by loud snoring. OSA affects about 5 to 10 percent of children 8 to 11 years old.

In the fight against brain damage caused by stroke, researchers have turned to an unlikely source of inspiration: hibernating ground squirrels.

Children vaccinated against influenza are significantly less likely to experience serious complications from the virus that could land them in hospital, new research from Public Health Ontario (PHO) and the Institute for Clinical Evaluative Sciences (ICES) has found.

ANN ARBOR, Michigan -- The immune cells that are trained to fight off the body's invaders can become defective. It's what allows cancer to develop. So most research has targeted these co-called effector T-cells.

But a new study takes a step back and considers: What if the problem isn't with the effector T-cells but starts higher up the cellular chain?

And so researchers looked at naïve T-cells - a type of immune cell that hasn't yet been triggered to fight. Naïve T-cells differentiate into the fighter effector T-cells.

Astrocytes, the supporting cells of the brain, could play a significant role in the pathogenesis of Alzheimer's disease (AD), according to a new study from the University of Eastern Finland. This is the first time researchers discovered a direct association between astrocytes and AD. Published in Stem Cell Reports, the study investigated the brain cell function of familial AD patients by using stem cell technologies.

A new study published in the Journal of Public Health has shown that the majority of people in the United Kingdom do not understand the connection between weight issues and cancer. Obesity is associated with thirteen types of cancer, including those of the breast, kidney, bowel, and womb. However, after surveying 3293 adults, taken as representative of the UK population, researchers found that only a quarter of respondents were aware of the link between obesity and cancer.

Researchers at the Icahn School of Medicine at Mount Sinai have identified a protein that can be targeted to suppress growth of a common type of breast cancer known as "estrogen receptor positive" (ER+), including ER+ cancers that are resistant to standard treatments.

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.

Philadelphia, November 17, 2017 - Prematurity is the main complication of pregnancy, and 15 million babies are born preterm worldwide each year.

Progesterone is a natural hormone produced by the ovaries in early pregnancy, and then later by the placenta. A decline in progesterone action is implicated as one of the causes of spontaneous preterm labor and delivery. Physicians worldwide have investigated in many studies whether vaginal progesterone administration to women with a mid-trimester sonographic short cervix reduces the rate of preterm birth.

CHAPEL HILL, NC - 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.

According to research published in the American Journal of Pathology, the protein CXCL5 is found in much higher levels in older adults with much clearer heart arteries.
