Impact of high-performance sport on serum potassium values in athletes: a syste...
Tavares, Ana Sofia; Vieira, Daniela; Pires, Mariana Midões; Miranda, Vasco; Bellém, FernandoBackground: Potassium is an alkali metal and the most abundant cation in the body, which can be measured in serum, plasma, whole blood, and urine without preservatives. The release of potassium from the muscles into the bloodstream during intense exercise is related to the intensity of physical activity. Therefore, changes in the serum levels of potassium measured in the blood of individuals who practice sports...

Tavares, Ana Sofia; Bellém, Fernando; Vieira, Daniela; Miranda, Vasco; Pires, MarianaPotassium (K+) is a critical alkali metal and the most abundant cation in the body, primarily found inside cells. It's measurable in serum, plasma, whole blood, and urine. During intense exercise, potassium is released from muscles into the bloodstream, with levels related to exercise intensity. Potassium is essential for cell polarization and transmitting electrical impulses in the heart, so fluctuations in se...
Microscale is key to model current and future Maritime Antarctic vegetation
Matos, Paula; Rocha, Bernardo; Pinho, Pedro; Miranda, Vasco; Pina, Pedro; Goyanes, Gabriel; Vieira, GonçaloDespite being one of the most pristine regions in the world, Antarctica is currently also one of the most vulnerable to climate change. Antarctic vegetation comprises mostly lichens and bryophytes, complemented in some milder regions of Maritime Antarctica by two vascular plant species. Shifts in the spatial patterns of these three main vegetation groups have already been observed in response to climate change,...
