Engineers have determined for the first time the impact of a ring-shaped vortex on transporting blood flow in normal and abnormal ventricles within the human heart. In order to make the study possible, researchers have developed a novel ultrasound technology that makes screening cheaper and much easier.
The first embryonic stem (ES) cell trial for severe heart failure is launching now in Paris. The...
When tissues are deprived of blood, as happens during a stroke or heart attack, the lack...
A new study points to a convenient, free way to manage acute asthmatic episodes—...
The seemingly miraculous power of babies’ hearts to repair themselves after being injured has spurred a research team to investigate if this ability can be harnessed for new heart attack treatments.
Researchers have discovered that some scar-forming cells in the heart, known as fibroblasts, have the ability to become endothelial cells— the cells that form blood vessels. The finding could point the way toward a new strategy for treating people who have suffered a heart attack
Short-term modest weight gains in healthy, normal weight young adults was associated with more bad cholesterol levels in those who ate muffins cooked using saturated oil. However, individuals in the same study who ate muffins made with polyunsaturated oils had improved blood cholesterol profiles, according to a new study.
In acute asthma, various triggers, including viral illnesses and aeroallergens, can cause acute narrowing of the airways leading to a life-threatening respiratory crisis and sometimes death. Researchers have identified a novel factor that puts the brakes on airway smooth-muscle contraction relevant to asthma.
Lethal fibrosis in lungs of mice with idiopathic pulmonary fibrosis (IPF) can be reversed, say researchers. No drug on the market can do this. But the crew pulled it off, in mice, by temporarily restoring (a mimic of) one of the body’s own anti-fibrosis agents, sharply reduced in IPF: microRNA-29.
A new study shows that physical activity can improve memory performance in older people through increasing volume and blood flow in an area of the brain called hippocampus.
Researchers have known for decades that stress contributes to heart disease. But a new analysis shows mental stress may tax women’s hearts more than men’s.
New research shows that the lungs become more inflammatory with age and that ibuprofen can lower that inflammation. In fact, immune cells from old mouse lungs fought tuberculosis bacteria as effectively as cells from young mice after lung inflammation was reduced by ibuprofen.
A new genetic finding suggests that some people who are prone to hostility, anxiety and depression might also be hard-wired to gain weight when exposed to chronic stress, leading to diabetes and heart disease.
Over 500 million people worldwide carry a genetic mutation that disables a common metabolic protein called ALDH2. The mutation, which predominantly occurs in people of East Asian descent, leads to an increased risk of heart disease and poorer outcomes after a heart attack. Now, have learned for the first time specifically how the mutation affects heart health.
Researchers have found that when the protein matrix metalloproteinase-14 (MMP-14) is reduced or lost, white blood cells, known as macrophages, become good and could prevent hardening of the arteries, rupture and sudden death.
Carbon nanotubes serve as bridges that allow electrical signals to pass unhindered through new pediatric heart-defect patches invented at Rice University and Texas Children’s Hospital.
Hope for healthier airways may be on the horizon thanks to a human airway muscle-on-a-chip that could be used to test new drugs because it accurately mimics the way smooth muscle contracts in the human airway, under normal circumstances and when exposed to asthma triggers.
A new study has shown that people who eat more protein- whether from plant or animal sources- tend to have a lower risk of hypertension, also known as high blood pressure.
Like everything else in the body, the white-matter fibers that allow communication between brain regions also decline with age. In a new study, researchers found a strong association between the structural integrity of these white-matter tracts and an older person’s level of daily activity.
A new study shows how schizophrenia is associated with increased rates and intensity of tobacco smoking by showing that the level of nicotine receptors in the brain was lower in schizophrenia patients than in a matched healthy group.
A research team is looking at whether an antibiotic has the potential to prevent or treat irregular heartbeats brought on by other medicines, thanks to a grant from national charity in the UK.
For the first time, scientists have turned human skin cells into transplantable white blood cells, soldiers of the immune system that fight infections and invaders.
On this episode of Bioscience Technology This Week, Christina Jakubowski discusses a new study that shows a link between idiopathic pulmonary fibrosis cases and asbestos exposure. Our second story showcases how immune cells use two critical receptors to clear dead cells from the body.
People with asthma often have a hard time dealing with respiratory viruses such as the flu or the common cold, and researchers have struggled to explain why. Now, the answer is becoming clearer.
A team of investigators has made a thought-provoking discovery about a type of cholesterol previously believed to be a "bad guy" in the development of heart disease and other conditions.
It may look like fresh blood and flow like fresh blood, but the longer blood is stored, the less it can carry oxygen into the tiny microcapillaries of the body, says a new study.
Smoking is banned in more than eight out of 10 U.S. homes— nearly twice as many as two decades ago, according to a new government study. The Centers for Disease Control and Prevention found smoking is even forbidden in nearly half of homes where an adult smoker resides.
A team of researchers has uncovered an intriguing link between heart attacks and a protein that is of great interest to drug companies for its impact on cholesterol.
"Do-it-yourself" blood pressure measurements and medicine changes work better than usual doctor-office care in some patients, a study of older adults in England found.
