Physiological Response to Breathing Hot Air

From liquid to air: breathing after birth.

Studying the transition from placental to pulmonary gas exchange has always been an intriguing and difficult challenge. Lung liquid is partly cleared before and during labour, but residual liquid must be cleared after birth. Where the liquid goes at the moment air is drawn into the lungs is unclear, but recent evidence indicates that it is transiently retained within the interstitial tissue cau...

Pulmonary vascular response to air-breathing exercise in humans following an 8-h exposure to hypoxia.

This study is concerned with the pulmonary vasculature in euoxia after preconditioning with 8h of hypoxia. The particular question we ask is whether the pulmonary vasculature will dilate normally with exercise or retain some degree of vasoconstriction, as has previously been reported in studies involving longer exposures to the hypoxia of high altitude. Ten subjects were studied on two separate...

RESPONSE OF METACARPAL FRACTURE FIXATION CONSTRUCTS TO PHYSIOLOGICAL LOADINGS

This study compares the functional capabilities of different metacarpal fixation constructs under physiological loadings in an attempt to identify the optimal construct rather than the strongest one. One hundred and twenty-six preserved human metacarpals were mechanically tested after oblique osteotomies and internal fixation. Maximum load to failure, average structural rigidity, and energ...

Physiological Response of Quinoa to Nitrogen Application under Salinity Conditions

Salinity stress is one of the major abiotic stresses which injures plants by limited water absorption and nutrient imbalance and limits crop growth. In order to study the effect of nitrogen fertilizer on physiological traits of quinoa at high salt concentrations, a greenhouse experiment was conducted in a factorial arrangement based on a randomized complete block with three replications in 2019...
