Synched Work Schedules during “Antarctic Summer” May Affect Sleep, Wake Hormones
Released March 9, 2017 - The continuous daylight conditions of summer in Antarctica are known to interfere with physiological functions such as sleep patterns and the release of melatonin, a hormone associated with circadian rhythms and sleep. Now, a study offers new information about why people in this region sleep poorly, and suggests that social behavior may also play a role. The study, published ahead of print in the Journal of Applied Physiology, was chosen as an APSselect article for March.
Caffeine Reduces Oxidative Stress, Improves Oxygen-Induced Lung Injury
Released March 8, 2017 - A new study finds that caffeine may protect the lungs from damage caused by prolonged oxygen therapy, such as oxygen supplementation given to premature babies. The article is the first of its kind to study the positive effects of caffeine on the lungs’ minute tissue structures. It is published ahead of print in the American Journal of Physiology—Lung Cellular and Molecular Physiology.
“Superhero Physiology: the Case for Captain America”
Released February 28, 2017 - A common challenge to educators across all disciplines is making learning interesting for students. Researchers from Mississippi State University outline a compelling strategy to teach physiology to undergraduate students: using real physiological concepts to explain some of the extreme physical transformations of the fictional superhero Captain America. The article is published in Advances in Physiology Education.
Raising Dietary Potassium to Sodium Ratio Helps Reduce Heart, Kidney Disease
Released February 21, 2017 - Reducing sodium (salt) in the diet has been recommended to lower blood pressure and the risk of heart disease. However, in a new review article, University of Southern California researchers found that increasing dietary potassium is as important to improving the risk factors for cardiovascular and kidney disease as limiting dietary sodium. The article is published ahead of print in the American Journal of Physiology—Endocrinology and Metabolism.
Sports-Related Concussion Negatively Affects Heart Rate, Blood Pressure
Released February 9, 2017 - A new study finds that concussion causes short-term impairment of the cardiovascular system but that these cardiovascular symptoms typically resolve within three days of the injury. The article is published ahead of print in the American Journal of Physiology—Regulatory, Integrative and Comparative Physiology.
Researchers Find Unhealthy Gut Microbes a Cause of Hypertension
Released February 2, 2017 - Researchers have found that the microorganisms residing in the intestines (microbiota) play a role in the development of high blood pressure in rats. The study is published in Physiological Genomics. It was chosen as an APSselect article for February.
Whole-Body Heat Stress Lowers Exercise Capacity, Blood Flow in Men
Released February 1, 2017 - Researchers have found that prolonged exposure to high temperatures can raise both the skin and core temperature, reducing blood flow to the brain and limbs during exercise and limiting the ability to exercise for long periods. The study, the first of its kind to separate the effects of skin- versus internal-raised temperature (hyperthermia), is published in Physiological Reports.
APS Announces Move to Atypon for Journal Hosting
Released January 31, 2017 - APS will move its physiology research journal titles to Atypon’s Literatum platform, the professional and scholarly publishing industry’s technologically advanced and most widely used online publishing platform for hosting published content.
APS and ADI Announce Partnership to Provide Enhanced Scientific Community Support
Released January 31, 2017 - ADI will expand its financial support for a range of early career research awards across a number of fields, including cardiovascular, respiratory, physiological genomics and neural control and autonomic regulation as part of its new partnership with APS.
Food and Antibiotics May Change Microorganisms in Gut, Causing IBS
Released January 26, 2017 - A recent review of research suggests that changes to the microorganisms (microbiota) in the gastrointestinal (GI) tract may be a cause of irritable bowel syndrome (IBS). The review article is published in the American Journal of Physiology—Gastrointestinal and Liver Physiology.
Type, Not Just Amount, of Sugar Consumption Matters in Risk of Health Problems
Released January 19, 2017 - The type of sugar you eat—and not just calorie count—may determine your risk for chronic disease. A new study is the first of its kind to compare the effects of two types of sugar on metabolic and vascular function. The paper is published ahead of print in the American Journal of Physiology—Heart and Circulatory Physiology.
Fit after 100: Training Helps French Bicyclist Beat His Own World Record at 103
Released January 12, 2017 - Adults over 100 years old can still increase their athletic performance and physical fitness with regular training, researchers have found. The case study of Robert Marchand, the now 105-year-old who recently broke the 100+ cycling record—again—is published ahead of print in the Journal of Applied Physiology.
Nerve-Signaling Protein Regulates Gene Associated with Schizophrenia
Released January 5, 2017 - Researchers from the University of California, San Diego, have identified a protein that regulates a gene associated with schizophrenia. The study, published in the Journal of Neurophysiology, was chosen as an APSselect article for January.
