Researchers have reversed wrinkled skin and hair loss, hallmarks of aging, in a mouse model. When a mutation leading to mitochondrial dysfunction is induced, the mouse develops wrinkled skin and extensive, visible hair loss in a matter of weeks. When the mitochondrial function is restored by turning off the gene responsible for mitochondrial dysfunction, the mouse returns to smooth skin and thick fur, indistinguishable from a healthy mouse of the same age.
Exposure to secondhand smoke is causing thousands of still births in developing countries, according to new research carried out by the University of York.
People who received complementary therapy for curable cancers were more likely to refuse at least one component of their conventional cancer treatment, and were more likely to die as a result, according to researchers from Yale Cancer Center and the Cancer Outcomes, Public Policy and Effectiveness Research Center (COPPER) at Yale School of Medicine. The findings were reported today online in JAMA Oncology.
Older Asian-American immigrants are healthier and happier if they are socially active, connected to their families and communities and are able to maintain their cultural values while adapting to western culture, according to a new Rutgers study.
A clinical trial of the use of adrenaline in cardiac arrests has found that its use results in less than 1 percent more people leaving hospital alive -- but almost doubles the risk of severe brain damage for survivors of cardiac arrest. The research raises important questions about the future use of adrenaline in such cases and will necessitate debate amongst healthcare professionals, patients and the public.
Omega 3 is a type of fat. Small amounts of omega 3 fats are essential for good health, and they can be found in the food that we eat.
Heart disease is still the number one killer of US women, and hormone therapy remains a top treatment for menopause symptoms. A new study connects these two facts to demonstrate little effect of hormone therapy on artery thickness as a precursor to heart disease. Study results are published online today in Menopause, the journal of The North American Menopause Society (NAMS).
Nicotine exposure during pregnancy, whether from smoking cigarettes, or nicotine patches and e-cigarettes, increases risk of sudden infant death syndrome -- sometimes known as 'cot death' -- according to new research published in The Journal of Physiology.
Omega 3 supplements have little or no effect on the risk of heart disease, stroke or death -- according to new research led by the University of East Anglia, UK. Increased consumption of omega 3 fats is widely promoted globally because of a common belief that that it will protect against heart disease. But a new UEA-led Cochrane review -- the international gold standard for high quality, trusted health information - finds that omega 3 supplements offer little, if any, benefit.
Research by King's College London has found that English local authorities have failed to prioritize palliative and end-of-life care, despite the health care challenges posed by a rapidly aging population.
