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.
Measuring variability of heart rate may identify premature infants at risk of developing necrotizing enterocolitis, a serious inflammatory condition that can lead to death, according to Penn State College of Medicine researchers. Necrotizing enterocolitis, or NEC, may lead to destruction of the intestinal wall and vital organ failure. It affects 6 to 10 percent of premature infants within the first two weeks of life.
Using a zebrafish model, investigators have identified a drug compound that appears to reverse arrhythmogenic cardiomyopathy (ACM), a hereditary disease and leading cause of sudden death in young people.
A daily supplement of an extract found in tomatoes may improve the function of blood vessels in patients with cardiovascular disease, according to new research.
Infants exposed to rodent and pet dander, roach allergens and a wide variety of household bacteria in the first year of life appear less likely to suffer from allergies, wheezing and asthma, according to a new study.
The current state of science on the adverse health effects of marijuana use links the drug to several significant adverse effects including addiction, a new review reports.
A new study shows how exposure to air pollution early in life produces harmful changes in the brains of mice, including an enlargement of part of the brain that is seen in humans who have autism and schizophrenia.
Biomedical engineering students have designed a lightweight, easy-to-conceal shirt-like garment to deliver life-saving shocks to patients experiencing serious heart problems. The students say their design improves upon a wearable defibrillator system that is already in use.
Women age 55 or younger may fare worse than their male counterparts after having a heart attack, according to new research presented at the American Heart Association’s Quality of Care and Outcomes Research Scientific Sessions 2014. Researchers studied records and interviews of 3,501 people (67 percent women) who had heart attacks in the United States and Spain in 2008-12.
Many people with cystic fibrosis develop diabetes. The reasons for this have been largely unknown, but now researchers have identified a molecular mechanism that contributes to the raised diabetes risk.
Lack of blood flow and oxygen delivery to a baby during labor and delivery can result in a condition known as hypoxic-ischemic encephalopathy (HIE), which is treated by whole body cooling. Now, researchers report on the feasibility of using a baby’s own cord blood cells to aid the injured brain in repairing itself.
Every year, more than 1 million people in the U.S. who have suffered heart attacks or chest pain from blocked arteries have little mesh tubes called stents inserted into their blood vessels to prop them open. The procedure has saved many lives, but it still has potentially deadly downsides. Now scientists are reporting that coating stents with vitamin C could lower the implants’ risks even further.
A genetic variant linked to sudden cardiac death leads to protein overproduction in heart cells, scientists report. The discovery adds to scientific understanding of the causes of sudden cardiac death and of possible ways to prevent it.
