Brett Wong is on a mission to help uncover the mechanism that regulates our ability to withstand heat stress. The goal is to help improve survival rates among those who suffer the most during heat waves: the elderly and people with conditions such as diabetes and heart disease.
The award-winning University of Oregon doctoral degree students research is the first to identify histamine receptors as contributing to increased blood flow during heat stress. Skin blood flow is a key factor in compensating for exposure to prolonged heat waves. "These are the same receptors that are involved in seasonal allergies for which people take antihistamines," says Wong, who is the lead author on an article describing his findings in the November issue of the Journal of Physiology. Co-authors are Brad W. Wilkins, research associate, and Christopher Minson, assistant professor of human physiology and co-director of the UO Exercise and Environmental Physiology Laboratories.
Theirs is the first study designed to examine a potential role for histamine receptors in skin blood flow in humans. They tested the H1 and H2 histamine receptors and found that only the H1 receptor was involved in skin blood flow changes. The National Institutes of Health (Heart, Lung and Blood Institute) funded the study. "Many deaths in the Midwest have been associated with an inability to increase skin blood flow and regulate body temperature," Wong says. "If we can understand the basic science behind increasing skin blood flow in healthy young individuals, well be able to help at-risk populations."

Scientists have developed a new method of characterizing graphene’s properties without applying disruptive electrical contacts, allowing them to investigate both the resistance and quantum capacitance of graphene and other two-dimensional materials. Researchers from the Swiss Nanoscience Institute and the University of Basel’s Department of Physics reported their findings in the journal Physical Review Applied.
Graphene consists of a single layer of carbon atoms. It is transparent, harder than diamond and stronger than steel, yet flexible, and a significantly better...
The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.
The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...
Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
