Endothelins are proteins that constrict blood vessels and raise blood pressure. They are normally kept in balance by other mechanisms, but when they are over-expressed, they contribute to high blood pressure (hypertension) and heart disease.
A new study published online in Nature Communicationson November 4, 2019, reports that some melanomas, which are among the deadliest skin cancers, originate in melanocyte stem cells that are located within the hair follicles.
Some deadly skin cancers may originate in the pigment-making stem cells in hair follicles rather than in skin.
Some of the most deadly skin cancers may start in stem cells that lend color to hair, and originate in hair follicles rather than in skin layers, a new study finds.
Scientists have pinpointed cells in the immune system that could be key to tackling high blood pressure.
Leading experts in the field of sickle cell disease (SCD) research will convene in Washington, D.C., for the Physiological and Pathophysiological Consequences of Sickle Cell Disease conference (November 6–8). The conference, organized by the American Physiological Society, will explore SCD- the world's most prevalent single-gene mutation disease-; and new research on preventing and reversing its deadly consequences.
Urinary incontinence in women is common, with almost 50% of adult women experiencing leakage at least occasionally. Genetic or heritable factors are known to contribute to half of all cases, but until now studies had failed to identify the genetic variants associated with the condition.
People who use cocaine regularly are at high risk of coronary artery disease. A study in the Journal of Addiction Medicine, the official journal of the American Society of Addiction Medicine, reports that stopping or reducing cocaine use can potentially reverse the process of coronary atherosclerosis. The journal is published by Wolters Kluwer.
Scientists in Japan and the US have found that vitamin B3 nicotinamide may help treat pregnant women who suffer from preeclampsia by preventing strokes and in some cases, even stimulating the growth of their fetus.
The results of numerous high-impact clinical trials that could affect kidney-related medical care will be presented at ASN Kidney Week 2016, November 15-20 at McCormick Place in Chicago, IL.
Selexipag is approved for long-term treatment of pulmonary arterial hypertension (PAH) in adults with moderate to severe symptoms.
The popular kids' card game "Exploding Kittens" teaches a concept critical to cancer science: When a player plays a "Nope" card, the subsequent player may lay another "Nope", thus creating a double-negative that becomes a positive, allowing the initial action to proceed.
A study in the Journal of the American Society of Nephrology suggests a new therapeutic approach to treat the development of chronic kidney disease secondary to chronic heart failure, known as cardiorenal syndrome type 2.
A pair of molecular signals controls skin and hair color in mice and humans — and could be targeted by new drugs to treat skin pigment disorders like vitiligo, according to a report by scientists at NYU Langone Medical Center.
No matter the trigger -- bug bites, a medication side-effect or an itchy wound -- the urge to scratch can be a real pain. Researchers at the Duke University Medical Center have identified a potential drug target in the skin for that itchy feeling.
New blood biomarkers reflecting vasoreactivity in lung blood vessels of patients with heart- and lung disease, can lead to simplified diagnostics and better evaluation of treatment for patients with the condition pulmonary arterial hypertension (PAH).
Endothelin (ET) is a peptide produced by cells in the blood vessels and has powerful vessel-constricting effects. Although endothelin is mainly associated with its role in blood pressure control and cardiovascular diseases, it continues to appear in other physiological functions and diseases.
Amyotrophic lateral sclerosis (ALS) is a disorder in which cells of the nervous system die, leading to muscle weakness that impacts breathing, movement and other physical functions.
Ethiopians have lived at high altitudes for thousands of years, providing a natural experiment for studying human adaptations to low oxygen, a condition known as hypoxia. One factor that may enable Ethiopians to tolerate high altitudes and hypoxia is the endothelin receptor type B (EDNRB) gene.
Updated guidelines on the treatment of idiopathic pulmonary fibrosis (IPF) have been released by an international group of leading respiratory societies, The new guidelines, issued by the American Thoracic Society, the European Respiratory Society, the Japanese Respiratory Society, and the Latin American Thoracic Association, were published in the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine.
For people who use cocaine, stopping or reducing cocaine use is associated with decreased levels of endothelin-1 (ET-1)--a protein that plays a key role in the development of coronary artery disease, reports a study in the Journal of Addiction Medicine, the official journal of the American Society of Addiction Medicine.
