Clinical interpretation of cardiac troponin in athletes: From endurance exercise to exertional injury

PM&R, EarlyView.
Abstract Exertional heat illness (EHI) and exertional rhabdomyolysis (ER) are increasingly recognized causes of morbidity in competitive and tactical athletes. Cardiac troponin (cTn) elevation, traditionally viewed as a marker of myocardial necrosis, may also be seen in these settings and can create significant diagnostic and prognostic uncertainty ...

Depositional and Hydrological Relationships Between Buried Dead Ice and the Active Layer in the McMurdo Dry Valleys, Antarctica: A Study of Sediment Geochemistry and Cation Concentrations

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT The McMurdo Dry Valleys, the largest ice‐free region in Antarctica, are home to a cold‐desert hydrologic system of glaciers, snowbanks, streams, and lakes. Freshwater is also stored as dead glacial ice, which is poorly constrained in terms of ion concentrations and interactions with both in situ and overlying sediments.

The most threatened plants receive the least scientific attention

PLANTS, PEOPLE, PLANET, EarlyView.
Plants sustain all life, providing the energetic and structural basis of ecosystems, but they face a growing risk of extinction. Reversing this decline requires an understanding of how scientific knowledge is distributed among species, and identification of the biases and gaps that hinder effective responses to the threats they face. However, we reveal
