Impact of high-performance sport on serum potassium values in athletes: a syste...
Tavares, Ana Sofia; Bellém, Fernando; Vieira, Daniela; Miranda, Vasco; Pires, MarianaPotassium is an alkali metal and the most abundant cation in the human body, measurable in serum, plasma, whole blood, and urine. The release of potassium from muscles into the bloodstream during intense exercise is related to the intensity of physical activity. Therefore, changes in serum potassium levels in individuals who regularly engage in sports can have significant consequences for the performance and he...
Impacto de doses suprafisiológicas de esteroides anabolizantes nos níveis de gl...
Ferreira, Bárbara; Leite, Beatriz; Calixto, Carolina; Bellém, Fernando; Tavares, Ana SofiaOs esteroides anabolizantes androgénicos são compostos sintéticos com estrutura química semelhante à testosterona. São frequentemente usados por atletas recreativos para aumentar a massa muscular, força e diminuir a massa gorda. No entanto, os esteroides anabolizantes androgénicos também podem ter efeitos adversos na saúde, incluindo alterações nos níveis de glicose e insulina. A presente revisão sistemática te...

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...
Impact of non-therapeutic doses of anabolic steroids on glucose and insulin lev...
Tavares, Ana Sofia; Ferreira, Bárbara; Leite, Beatriz; Calixto, Carolina; Bellém, FernandoBackground: Anabolic androgenic steroids (AAS) are synthetic compounds with a chemical structure similar to testosterone. Bodybuilders frequently use them to increase muscle mass, and strength, and reduce body fat. However, AAS can also have adverse effects on health, including alterations in glucose and insulin levels. Aims: This systematic literature review aimed to collect and critically analyze studies that...
Impact of supraphysiological doses of anabolic steroids on glucose and insulin ...
Tavares, Ana Sofia; Bellém, Fernando; Ferreira, Bárbara; Leite, Beatriz; Calixto, CarolinaTestosterone (TE) is an anabolic androgenic steroid (AAS) that promotes muscle growth and the maintenance of secondary sexual characteristics. Due to its aesthetic benefits, AASs have become popular in sports, typically administered orally or intramuscularly, with doses up to 100 times higher than the therapeutic dose. A therapeutic dose is safe and sufficient for the desired effect, while a supraphysiological ...

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...
Benefits of fiber and polyphenols in lowering cholesterol levels: perception of...
Marques, Alexandra; Coelho, Ana; Paulos, Ema; Bellém, Fernando; Almeida, Ana; Ladeira, CarinaCardiovascular diseases constitute the leading cause of death in Portugal. Individuals who develop this class of pathologies present an underlying clinical condition, called atherosclerosis. The condition of hypercholesterolemia is a major risk factor for the development of atherosclerosis and, consequently, cardiovascular diseases. Thus, the prevention of cases of hypercholesterolemia constitutes a preventive ...

Tavares, Ana Sofia; Bellém, Fernando; Abreu, Renato; Leitão, Maria do Céu; Medeiros, Nuno; Alves, Patrícia; Calmeiro, LuísCurrently, the main public health concern worldwide is the COVID-19 pandemic, caused by SARS-CoV-2, which was recently discovered and described. Due to its high pathogenicity and infectiousness, it is necessary to determine the risk healthcare professionals face every day while dealing with infected patients and contaminated biological samples. The purpose of this study was to assess Portuguese Biomedical Scien...

Cyanobacteria in freshwater: influence in liver morbidity in expose Alentejo’s ...
Bellém, Fernando; Santos, Carlos Silva; Carolino, Elisabete; Morais, ManuelaTaking nutrients from the water column, phytoplankton can present high levels of growth and blooms arise if growth rates reach densities over 2.000 cells/ml. Cyanobacteria (prokaryotic, photosynthetic microorganisms) is one group of this community and can produce toxins responsible for human injury after the acute or systematic exposition. The main goal of this work is to correlate cyanobacteria blooms in Alent...
