The American Heart Association's first policy statement on electronic cigarettes backs them as a last resort to help smokers quit. The American Cancer Society has no formal policy but quietly took a similar stance in May.
A new study of 9- and 10-year-olds finds that those who are more aerobically fit have more fibrous and compact white-matter tracts in the brain than their peers who are less fit.
Mice missing two important proteins of the vascular system develop normally and appear healthy in adulthood, as long as they don’t become injured. If they do, their wounds don’t heal properly, a new study shows.
On this episode of Bioscience Technology This Week, Christina Jakubowski reports on the possibility of making nuts safer to eat for those with allergies. Our second story tackles important questions about which genes may drive antibiotic resistance.
Links between a number of common respiratory diseases and an increased risk of developing lung cancer have been found in a large pooled analysis of seven studies involving more than 25,000 individuals.
A large international study questions the conventional wisdom that most people should cut back on salt, suggesting that the amount most folks consume is OK for heart health - and too little may be as bad as too much.
Scientists from the University of Leeds have discovered a gene that plays a vital role in blood vessel formation, research which adds to our knowledge of how early life develops. The discovery could also lead to greater understanding of how to treat cardiovascular diseases and cancer.
Researchers have discovered a previously unknown cardiac molecule that could provide a key to treating, and preventing, heart failure. The newly discovered molecule provides the heart with a tool to block a protein that orchestrates genetic disruptions when the heart is subjected to stress, such as high blood pressure.
Cognitive abilities such as memory and attention are not only important after a stroke but also before. Previous studies have shown poor cardiovascular health can increase the risk of cognitive impairment such as problems in memory and learning. However, the opposite idea that cognitive impairment may impact cardiovascular health, specifically stroke, was not established before.
New research suggests that microRNAs may be able to relay valuable information about damage to the heart: Scientists have linked an increase in certain microRNAs circulating in the blood with injury to cardiac muscle.
Young adults who were breastfed for three months or more as babies have a significantly lower risk of chronic inflammation associated with cardiovascular and metabolic diseases, according to research from the Brown School at Washington University in St. Louis.
A probiotic that prevents obesity could be on the horizon. Bacteria that produce a therapeutic compound in the gut inhibit weight gain, insulin resistance and other adverse effects of a high-fat diet in mice, Vanderbilt University investigators have discovered.
Researchers of the Max Planck Institute of Molecular Cell Biology and Genetics in Dresden report how they managed to capture detailed three-dimensional images of cardiac dynamics in zebrafish. The novel approach: They combine high-speed Selective Plane Illumination Microscopy (SPIM) and clever image processing to reconstruct multi-view movie stacks of the beating heart.
Eating probiotics regularly may modestly improve your blood pressure, according to new research. Probiotics are live microorganisms (naturally occurring bacteria in the gut) thought to have beneficial effects; common sources are yogurt or dietary supplements.
A daily low-dose aspirin is widely prescribed for the prevention of cardiovascular disease. Now, a new study suggests that common genetic variation may modify the cardiovascular benefit of aspirin.
Reducing the amount of alcoholic beverages consumed, even for light-to-moderate drinkers, may improve cardiovascular health, including a reduced risk of coronary heart disease, lower body mass index (BMI), and blood pressure, according to a new multi-center study.
On this episode of Bioscience Technology This Week, Editor-in-Chief Rob Fee reports on the possible double-punch of tick bites and how to control and undo years of heart damage.
An association between high blood cholesterol and breast cancer has been found in a study of more than 1 million patients over a 14-year time period in the UK.
Almost 40 percent of pancreatic cancers– one of the deadliest forms of cancer– could be avoided in the UK through maintaining a healthy weight and not smoking, according to new research.
In a new study, scientists explain that running, when accompanied by visual stimuli, restored brain function to normal levels in mice that had been deprived of visual experience in early life.
Adults who watch TV for three hours or more each day may double their risk of premature death compared to those who watch less, according to new research.
Scientists have found that eating almonds in your diet can reduce the risk of heart disease by keeping blood vessels healthy and significantly increasing the amount of antioxidants in the blood stream.
Researchers have shown that a favorable electrical property is present in a type of protein found in organs that repeatedly stretch and retract, such as the lungs, heart and arteries. These findings are the first that clearly track this phenomenon, called ferroelectricity, occurring at the molecular level in biological tissues.
By scouring the DNA of thousands of patients, researchers have discovered four rare gene mutations that not only lower the levels of triglycerides, a type of fat in the blood, but also significantly reduce a person’s risk of coronary heart disease—dropping it by 40 percent. The mutations all cripple the same gene, called APOC3, suggesting a powerful strategy in developing new drugs against heart disease.
Stanford University researchers have devised a noninvasive way to detect heart-transplant rejection weeks or months earlier than previously possible. The test, which relies on the detection of increasing amounts of the donor’s DNA in the blood of the recipient, does not require the removal of any heart tissue.
