Orlando, Fla. (April 7, 2019)--A new study suggests that sunscreen protects the skin's blood vessel function from harmful ultraviolet radiation (UVR) exposure by protecting dilation of the blood vessels. Perspiration on the skin may also provide protection to the skin's blood vessels from sun damage. The findings will be presented today at the American Physiological Society's (APS) annual meeting at Experimental Biology 2019 in Orlando, Fla.
Orlando, Fla. (April 7, 2019)--Estradiol is a commonly prescribed estrogen therapy. Previous research has found that rats treated with the hormone experience an increase in sugar consumption. But according to new research, blocking the body's opioid receptors can reverse this effect. The findings will be presented today at the American Physiological Society's (APS) annual meeting at Experimental Biology 2019 in Orlando, Fla.
Orlando, Fla. (April 7, 2019) - Researchers are reporting new findings on how bacteria involved in gum disease can travel throughout the body, exuding toxins connected with Alzheimer's disease, rheumatoid arthritis and aspiration pneumonia. They detected evidence of the bacteria in brain samples from people with Alzheimer's and used mice to show that the bacterium can find its way from the mouth to the brain.
ARLINGTON, Virginia, April 6, 2019 -- Heart attack victims over age 65 are less likely than younger patients to receive timely percutaneous coronary intervention to open their blocked heart arteries, according to preliminary research presented at the American Heart Association's Quailty of Care and Outcomes Research Scientific Sessions 2019, a premier global exchange of the latest advances in quality of care and outcomes research in cardiovascular disease and stroke for researchers, healthcare professionals and policymakers.
A clinical review, published today (Saturday 6 April 2019) for the BMJ, provides new interim advice for doctors and clinicians in prescribing cannabis-based products and cannabinoids to treat certain conditions.
Since a policy change in November 2018, specialist doctors registered with the General Medical Council (GMC), have been permitted to prescribe new medicines which derive from cannabis. Yet, research into these products has, to date, been limited creating an 'information vacuum' about these medicines, their benefits or harms.
Orlando, Fla. (April 6, 2019) - Acetaminophen -- a commonly used pain reliever and fever reducer -- is the leading cause of quickly developing, or acute, liver failure in the U.S. Findings from a new mouse study suggest that treatments that increase levels of the protein thrombospondin-1 could help the liver recover from an overdose of acetaminophen.
PHILADELPHIA (April 5, 2019) -Breastfeeding is an accepted practice for millions of women worldwide and strongly endorse by the World Health Organization. To provide appropriate counseling about human milk and breastfeeding, it is important to understand cultural beliefs and customs related to the practice.
Researchers have known for decades that inflammation accompanies Alzheimer's disease (AD) brain lesions. Several early studies suggested that "super-aspirins" or Nonsteroidal anti-inflammatory drugs (NSAID) could help avoid the disease. However, after clinical trials showed that NSAIDs don't help patients who already have AD symptoms, doctors wondered whether these drugs could still be helpful to people who were at risk of developing the disease, but weren't yet showing symptoms.
Although the majority of patients who have blood cancers are older adults, they make up only a small percentage of participants in the clinical trials that lead to new therapies. That's because the standard research methods used in oncology (cancer medicine) are not ideal for identifying certain vulnerabilities linked to aging, such as having multiple chronic diseases and being frail.
ITHACA, N.Y. - Dr. Sunita Sah practiced general medicine for several years in the United Kingdom's National Health Service. When she came to the United States, she noticed something strange.
The U.K. guidelines for tests such as mammograms and colon cancer screenings drastically differed from those in the U.S. - even though they were based on the same medical evidence.
April 5, 2019 -- Even tiny amounts of gluten in foods are troublesome for people with celiac disease, and restaurants may be the hardest places to avoid the protein, finds a study by Benjamin Lebwohl, MD, MS, Celiac Disease Center at NY-Presbyterian Hospital and assistant professor of medicine and epidemiology at Columbia Mailman School. More than half of gluten-free pizza and pasta dishes in restaurants tested positive for the presence of gluten; about one-third of supposedly gluten-free foods had detectable gluten.
With new genome analysis tools, scientists have made significant advances in our understanding of modern humans' origins and ancient migrations.
But trying to find ancient DNA, let alone prove that the ancient DNA is ancestral to a population living today is extremely challenging.
The health claims made on the product packaging for a large proportion of foods marketed to children in the UK are 'confusing', and could be contributing to rising rates of childhood obesity, suggests research published online in the Archives of Disease in Childhood.
Stricter regulations are needed for food labelling and product content to lessen this risk, urge the researchers
Mass drug administration (MDA) of two antibiotics can be highly effective at reducing cases of scabies and the bacterial infection impetigo, according to new research published in Lancet Infectious Diseases.
The study was conducted by the London School of Hygiene & Tropical Medicine (LSHTM), Murdoch Children's Research Institute (MCRI), the Kirby Institute at UNSW Sydney and the Solomon Islands Ministry of Health and Medical Services.
TROY, N.Y. --Hypertrophic cardiomyopathy is best known for revealing itself in one certain way: as an unexpected, fatal heart attack during strenuous exercise. But researchers suspect as many as 300 mutations can individually cause enlargement of the heart that renders it vulnerable to strain. Recent studies examining three of those mutations at the molecular level found separate mechanisms at work, said Rensselaer Polytechnic Institute muscle protein and contraction expert Doug Swank, whose most recent paper on the topic was published today in the Journal of Physiology.
