The vascular response to local skin cooling is dependent in part on a cold-induced translocation of α2C-receptors and an increased α-adrenoreceptor function. To discover whether β-adrenergic function might contribute, we examined whether β-receptor sensitivity to the β-agonist isoproterenol was affected by local skin temperature. In seven healthy volunteers, skin blood flow was measured from th...
Brown/beige adipocytes are therapeutic targets to combat obesity due to their abilities to dissipate energy through adaptive thermogenesis. Most studies investigating induction of brown/beige adipocytes were conducted in cold condition (e.g., 4°C); much is unknown about how the thermogenic program of brown/beige adipocytes is regulated in thermoneutral condition (e.g., 30°C), which is within th...
Homeothermic endothermy, the maintenance of a high and stable body temperature (Tb) using heat produced by elevated metabolism, is energetically expensive. There is increasing evidence that the earliest endotherms were heterotherms that, rather than maintaining strict homeothermy, allowed Tb to fluctuate with large variations between active and rest-phase Tb. The high level of homeothermy obser...
The purpose was to study age related changes in circulatory system via Ballistocardiography (BCG) by utilizing Electromechanical Film (EMFi) sensors by gradually changing the ambient temperature from a thermoneutral area to cold direction. ECG and BCG were recorded from a young person (23 years) and from an older person (78 years), both males. During the tests, brachium blood pressure (BP) and ...
Heat stress is one of the most critical factors affecting human life. In Central Europe, its influence noticeable, especially in Polish–Saxon region, which a very popular tourist region also inhabited by high number elders. The main goal this paper was to assess multi-annual changes heat occurring considering frequency days, UTCI (Universal Thermal Climate Index), and circulation conditions. re...
Although high-temperature proton exchange membrane electrolyzer cells (HT-PEMECs) have been promising devices to store energy in recent years, the effect of certain parameters on their performance is still unclear. Therefore, a 2D multiphysics model adopted study related processes electrochemical reactions an HT-PEMEC. The validated by comparison with experimental data. Subsequently, effects ap...
Abstract The realization of the thermoregulating function electronic skin (e‐skin) by simulating human temperature perception system can greatly improve intelligence e‐skin. Here, we report a e‐skin that fits on surface prosthetic limb based hybrid structure consisting flexible thermoelectric device and phase‐change heat sink. possesses outstanding adaptability similar to body; it maintain at 3...
