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.
High cholesterol levels may impair fertility in couples trying to achieve a pregnancy, according to a new study. Couples in which each partner had a high cholesterol level took the longest time to reach pregnancy, the study showed.
Children with progeria, a rare disorder that causes premature aging, die in their teens of ailments that are common in octogenarians: heart failure and stroke. Kan Cao, a University of Maryland assistant professor of cell biology and molecular genetics, urgently wants to help find a cure. Cao and her colleagues have taken a big step in that direction, showing that a toxic protein destroys muscle cells inside the patients’ arteries.
Adding vitamin D to asthma treatment to improve breathing only appears to benefit patients who achieve sufficient levels of the supplement in the blood. Overall, the ability to control asthma did not differ between a study group that received vitamin D supplements and a group that received placebo, according to new research.
There is bad news for those who believe drinking red wine is protecting their hearts and extending their lives. A study found that a plant compound in grapes—resveratrol—may not provide such health benefits. The nine-year study found resveratrol had no significant effect on longevity, inflammation, cardiovascular disease, or cancer.
A new study of preschools and day care centers finds that flame retardants are prevalent indoors, potentially exposing young children to chemicals known to be hazardous.
The caffeine in coffee that might help get you going in the morning can be lifesaving for premature babies. For more than a decade, neonatologists have routinely given premature newborns caffeine as a respiratory stimulant, helping their immature lungs and brains remember to breathe.
New research has identified a genetic mutation responsible for the cluster of cardiovascular risk factors that comprise the obesity-related metabolic syndrome.
In a major scientific review of research on e-cigarettes, scientists found that industry claims about the devices are unsupported by the evidence to date, including claims that e-cigarettes help smokers quit.
Researchers are evaluating whether vitamin D can slow the development of cardiovascular problems in African Americans with diabetes. They are more likely to die from cardiovascular disease than Caucasians with diabetes.
Harvard scientists have merged stem cell and “organ-on-a-chip” technologies to grow, for the first time, functioning human heart tissue carrying an inherited cardiovascular disease. The research appears to be a big step forward for personalized medicine, because it is working proof that a chunk of tissue containing a patient’s specific genetic disorder can be replicated in the laboratory.
In a world-first, researchers have discovered one of the main reasons behind why cancer spreads throughout the body: the help of "bad" cholesterol. The research found that LDL regulates the machinery that controls cell migration.
An antioxidant that targets specific cell structures—mitochondria—may be able to reverse some of the negative effects of aging on arteries, reducing the risk of heart disease, according to a new study by the University of Colorado Boulder.
A futuristic anti-aging approach, variously described and utilized by three different Harvard and Stanford groups this week, may hit the clinic by year’s end. The research all began with “heterochronic parabiosis.” That is, old mice were hooked up to young mice via their circulatory systems— and experienced tissue rejuvenation.
Stem cell therapy can regenerate heart muscle in primates, according to a new study. The scientists on this and related projects are seeking way to repair hearts weakened by myocardial infarctions.
A type of cell that builds mouse hearts can renew itself, researchers report. They say the discovery, which likely applies to such cells in humans as well, may pave the way to using them to repair hearts damaged by disease— or even grow new heart tissue for transplantation.
