Amino acid solution mitigates hypothermia response and intestinal damage following exertional heat stroke in male mice
Exertional heat stroke (EHS) is a debilitating and potentially fatal condition for which few prevention strategies exist. These results suggest that a 5AAS improves Tc regulation during EHS recovery through maintaining mucosal function and integrity and that protecting the GI tract during EHS may be beneficial in some of the health consequences of EHS exposure. AbstractIncreased gut permeability is implicated in the initiation and extent of the cytokine inflammatory response associated with exertional heat stroke (EHS). The primary objective of this study was to determine if a five amino acid oral rehydration solution (5AA...

Three cases of immune ‐mediated necrotizing myopathy with anti‐signal recognition particle antibodies: Extramuscular symptoms preceding progressive muscle weakness
ConclusionsAll three patients visited the internal medicine department before the neurology department. It is important to consider anti ‐SRP myopathy as a differential diagnosis for patients presenting with elevated creatine kinase levels and extramuscular symptoms.

Liver Injury Associated with Sporting Activities
Semin Liver Dis 2018; 38: 357-365 DOI: 10.1055/s-0038-1670656Exertional heat stroke most commonly develops following prolonged levels of aerobic activity in a warm or humid environment. Hypoperfusion of the vital organs along with activation of the inflammasome can lead to progressive and potentially fatal multiorgan failure including acute liver failure. In the United States, herbal and dietary supplements that are marketed to improve performance, strength, and weight loss are increasingly being used by both amateur and professional athletes. Consumption of bodybuilding supplements that contain androgenic anabolic steroid...

Microcirculatory Disorders and Protective Role of Antioxidant in Severe Heat Stroke: A Rat Study
This study aims to examine microcirculation and systemic hemodynamic disturbances in severe heat stroke (HS). A total of 147 rats were divided into HS group (HS), pretreated with superoxide dismutase (SOD+HS) group, and pretreated with normal saline (NS+HS) group. Heat stress was induced by incubating the animals in certain temperatures. Blood flow and vascular reactivity were monitored dynamically with intravital microscopy. Pulmonary permeability was reflected by wet-to-dry weight ratio, the concentration of Evans Blue (EB), and histopathology of lung. The results showed that heat stress could induce blood flow rate redu...

No pain, no gain? Getting the most out of exercise
Staying in shape has all sorts of benefits, from maintaining heart health to warding off dementia and cancerInactivity – fuelled by cars and a sedentary work life – has been dubbed the biggest public health problem of the 21st century, a global pandemic with dramatic impact on peoples wellbeing. The latest reports suggest that around the world it was responsible for 5.3 million deaths in 2008 – around one in 10 – more deaths than smoking.Not only does exercise make you fitter, it can also ward off numerous and often unexpected diseases, from heart attacks, to diabetes, some forms of cancer and dementia. There are t...
