High systolic blood pressure – the top number in a blood pressure reading – has long been considered an indicator of cardiovascular disease risk for adults over 50. But now a new Northwestern Medicine study suggests that it’s also important for younger adults.
Using the same technology that made smartphone cameras possible, scientists at Columbia University Medical Center are capturing images of individual molecules at a level of detail never before possible—including images of a molecule implicated in heart disease and muscle diseases.
"Washington University cardiologist Zachary Goldberger once made music out of heartbeats. Now, with a Beethoven scholar and a medical historian, he has discovered that three musical compositions that Beethoven created while stressed are arrhythmic in a way mirroring the composer's own probable heart arrhythmias."
Researchers have determined that two mutations on a single gene can interact in a way that lowers the carrier's risk for a heart attack. The variants are found in a gene called DBH, which regulates an enzyme involved in the conversion of dopamine to norepinephrine - both of which are important chemical messengers and hormones.
This is the first official look at the life sciences division of Google X.
The Food and Drug Administration (FDA) has approved for evaluating in people a nanoparticle-based imaging agent jointly developed at Washington University School of Medicine in St. Louis and the University of California, Santa Barbara, in collaboration with Texas A&M University.
Times have changed. It used to be that an apple a day kept the doctor away. But three recent studies indicate this mantra could be changed to “a blueberry- avocado-cocoa-bean-smoothie a day” keeps the doctor away—if the doctor is a cardiologist.
Patients with sickle cell disease often suffer from painful attacks known as vaso-occlusive crises, during which their sickle-shaped blood cells get stuck in tiny capillaries, depriving tissues of needed oxygen. Blood transfusions can sometimes prevent such attacks, but there are currently no good ways to predict when a vaso-occlusive crisis, which can last for several days, is imminent.
A see-through zebrafish and enhanced imaging provide the first direct glimpse of how blood stem cells take root in the body to generate blood.
Scientists are unraveling a mystery behind a fairly common disease that leads to heart failure: Why do some people with a key mutated gene fall ill while others stay healthy? Researchers tested more than 5,200 people to tease apart when mutations really are harmful or are just bystanders.
Researchers have found a possible predictor for little understood -- but often disabling or even fatal -- stroke complications.
Scientists have found that a transcription factor protein may be critical for normal respiratory function.
The fructose-glucose mixture found in high-fructose corn syrup was more toxic to mice than sucrose or table sugar.
Studies consistently show that people born weighing 6 pounds or less face an increased risk for type 2 diabetes as adults.
Researchers have developed an entirely new type of pill that tricks the body into thinking it has consumed calories, causing it to burn fat.
Investigators working to unravel the impact of genetics versus environment on traits such as obesity may also need to consider a new factor: when individuals were born.
The Cleveland Clinic recently unveiled their annual Top 10 Medical Innovations for 2015– a list that casts an optimistic light on up-and-coming healthcare advances that may reach consumers next year.
Like human patients, mice with a form of Duchenne muscular dystrophy undergo progressive muscle degeneration and accumulate connective tissue as they age. Now, researchers at the Stanford University School of Medicine have found that the fault may lie at least partly in the stem cells that surround the muscle fibers.
Researchers at NYU Langone Medical Center have developed the first large animal model of an inherited arrhythmic syndrome – an advance that will lead to a better understanding of the biologic mechanisms important in normal heart conduction and rhythm.
A hard hit to the chest can cause an irregular heartbeat that may lead to death even days after the impact.
In a new study, researchers demonstrated an association between smoking and loss of the Y chromosome in blood cells. The researchers have previously shown that loss of the Y chromosome is linked to cancer.
The Mediterranean diet consistently has been linked with an array of health benefits, including decreased risk of chronic disease and cancer. Until now, however, no studies had associated the diet with longer telomeres, one of the biomarkers of aging. Read more...
These days, with the abundance of artificial light, TV, tablets and smartphones, adults and children alike are burning the midnight oil. What they are not burning is calories: with later bedtimes comes the tendency to eat. Read more...
Anyone who has experienced Los Angeles gridlock likely can attest that traffic may cause one's blood pressure to rise. But researchers have found that, beyond the aggravation caused by fellow drivers, traffic-related air pollution presents serious heart health risks.
Researchers had never shown exactly how cells in the brain stem detect carbon dioxide and regulate breathing in humans. After taking a mutation from a two-month-old baby and expressing it in human astrocytes, they did exactly that, and the research may lead to an early warning system to save premature infants.
