Advancing tele‐physiology: A chest patch solution for continuous, non‐invasive remote monitoring in a hypoxic environment

open access: yesExperimental Physiology, EarlyView.
Abstract Skin‐mounted sensors are thin, flexible and lightweight electronic devices that enable monitoring of multiple physiological parameters. The aim of this study was to provide pilot evidence for possible utilization of a sensorized patch for capturing the bodily response to hypoxia. The subsequent phases of the study comprised a case report and a

Daily hot‐water immersion preserves altitude‐induced haemoglobin mass expansion following descent independent of erythropoietin

open access: yesExperimental Physiology, EarlyView.
Abstract High‐altitude exposure increases haemoglobin mass (Hbmass), a key determinant of arterial oxygen‐carrying capacity, but following descent this adaptation can regress toward baseline within 7 days. Long‐term heat acclimation has emerged as an alternative stimulus for Hbmass expansion; however, whether post‐altitude passive‐heat exposure can ...

Ser ou não ser consiliente: eis a questão

open access: yesHistória, Ciências, Saúde: Manguinhos, 2001
Stephen J. Gould e Edward Wilson são autores emblemáticos de duas tendências opostas do darwinismo. A primeira defende a separação entre os duros fatos da natureza, tal como nos são apresentados pela teoria da seleção natural, e as questões de valor e ...

TMEM16A chloride channels in the female reproductive tract and their role in normal and dysfunctional pregnancy and labour

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend TMEM16A plays a pivotal role in setting the duration of the action potential plateau in human uterine smooth muscle. An increase in TMEM16A expression in labour underpins a lengthening of the plateau and this provides time for the contraction to become larger and longer, important for timely successful labour.

Ventilatory and cerebrovascular responses to exercise in lowlander children acclimatizing to high‐altitude

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend To investigate age‐related differences in ventilatory and cerebrovascular responses to exercise at high‐altitude, adults (n = 10, 23–44 years) and children (n = 8, 7–14 years) completed progressive cycling exercise tests at sea‐level and following 6 days of acclimatization at 3800 m.

Maximal exercise at high altitude does not exacerbate inflammation in the human brain

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend This study investigated arterial–internal jugular venous (IJV) exchange of cytokines in response to low‐intensity and maximal cycling exercise at sea level and following 6–8 days at 3800 m a.s.l. There was a shift towards net release of interleukin‐6 (IL‐6), interleukin‐8 (IL‐8), monocyte chemoattractant protein‐1 (MCP‐1) and ...

Mechanisms reducing parasympathetic activity in chronic hypoxia

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Parasympathetic activity is reduced in chronic hypoxia, but the underlying mechanism(s) are unclear. Using β‐adrenergic blockade to isolate parasympathetic control of heart rate at sea level and after 9‐12 days at high altitude, we investigated whether (i) chemoreflex activation, (ii) increased pulmonary ventilation and/or (iii ...

The influence of metaboreflex activation on pulmonary pressure with combined chemoreflex activation in acute and chronic hypoxia

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Activation of both the metaboreflex via post‐exercise circulatory occlusion and the chemoreflex via acute and chronic hypoxia increased pulmonary artery systolic pressure. Coactivation of these reflexes further increased pulmonary artery pressure in an additive manner.
