The combination of hypoxia and exercise offers significant potential benefits for non-athletic individuals, particularly in clinical and rehabilitation settings. Personalized hypoxic exercise programs can be tailored to improve cardiovascular and metabolic health, enhance recovery, and promote adaptation to low-oxygen environments. However, finding the optimal balance between exercise variables (intensity, duration, frequency, type of exercise), and hypoxic exposure parameters (altitude level, duration, session fr…

Plastic compounds released into the environment can be accumulated in human tissues causing various health issues. It has been demonstrated that Bisphenol A (BPA), widely used in polycarbonate plastics and food packaging, can accumulate in gastrointestinal (GI) tract, inducing oxidative stress, metabolic dysfunction, and other cellular disturbances, including mitochondrial damage. However, the mechanisms by which BPA affects the GI function and affects mitochondrial function in the absorptive cells of the intestin…

Abstract Objectives The presence of prostate‐specific antigen (PSA) in saliva and salivary glands has been reported. Nevertheless, its release pathway in these glands remains to be elucidated. Here, we showed PSA subcellular distribution focusing on its plausible route in human salivary parenchyma. Materials and Methods Sections of parotid and submandibular glands were subjected to the immunohistochemical demonstration of PSA by the streptavidin–biotin method revealed by alkaline phosphatase. Moreover, ultrathin s…

The use of hypoxic devices among athletes who train in normobaric hypoxia has become increasingly popular; however, the acute effects on heart and brain metabolism are not yet fully understood. This study aimed to investigate the mitochondrial bioenergetics in trained male and female Wistar rats after acute hypoxia training. The experimental plan included exercising for 30 min on a treadmill in a Plexiglas cage connected to a hypoxic generator set at 12.5% O2 or in normoxia. After the exercise, the rats were sacri…

Hemodynamic changes during exercise in acute hypoxia (AH) have not been completely elucidated. The present study aimed to investigate hemodynamics during an acute bout of mild, dynamic exercise during moderate normobaric AH. Twenty-two physically active, healthy males (average age; range 23–40 years) completed a cardiopulmonary test on a cycle ergometer to determine their maximum workload (Wmax). On separate days, participants performed two randomly assigned exercise tests (three minutes pedaling at 30% of Wmax): …
