Neuromuscular fatigability with repeated exercise in hypoxia: From single‐joint paradigms to sprints

The Journal of Physiology, EarlyView.
Abstract figure legend Acute hypobaric or normobaric hypoxic exposure accelerates neuromuscular fatigability during repeated exercise. Indices of peripheral and central fatigue are not different at exhaustion in mild, moderate and severe hypoxia compared with normoxia, but task failure occurs earlier.

Blood buffers: The viewpoint of a biochemist

Physiological Reports
Mammalian blood is a very complex system whose multiple physiological roles require that its pH is maintained constant, in spite of the necessity of carrying over 15 moles of CO2 a day from the tissues to the lungs. The blood pH is maintained constant by

Extensive Pulmonary Embolism in late pregnancy associated with Anticardiolipin Antibodies [PDF]

, 2004
The leading cause of morbidity and mortality during pregnancy and the puerperium is venous thromboembolism. Though uncommon, the risk is five times higher in a pregnant woman than in a non-pregnant woman of similar age.1,2 In pregnancy, all three ...

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

The 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.

Is There a Relationship Between Carbon Dioxide Fluctuations and Intraventricular Hemorrhage in Preterm Infants?

Cam & Sakura Medical Journal
Objective: This study aimed to examine the association between hypo/hypercapnia and fluctuations in carbon dioxide (CO2) levels and severe intraventricular hemorrhage (IVH) during the initial 72 hours of life among preterm infants. Material and Methods:

Evidence for Shear Stress-Mediated Dilation of the Internal Carotid Artery in Humans. [PDF]

, 2016
Increases in arterial carbon dioxide tension (hypercapnia) elicit potent vasodilation of cerebral arterioles. Recent studies have also reported vasodilation of the internal carotid artery during hypercapnia, but the mechanism(s) mediating this ...

Hypoxia and hypercapnia elicit overlapping but distinct skeletal muscle toxicities

The Journal of Physiology, EarlyView.
Abstract figure legend Hypoxia and hypercapnia cause overlapping skeletal muscle phenotypes, including atrophy, change in myofibre metabolic profile and myogenic response to injury. Both signals operate via distinct cellular pathways. Abstract Skeletal muscle dysfunction is strongly associated with elevated mortality in acute and chronic pulmonary ...

Relevance of hypocapnia to febrile seizures in children

Egyptian Pediatric Association Gazette, 2015
Background: Febrile seizure is the most common type of convulsion in children. However, there are scanty data on the mechanism of its development. The aim of this study was to evaluate the venous blood gas status in children with febrile seizures and to ...

Cerebral Vasomotor Reactivity: Impact of Hyperventilation Induced Hypocapnia on Hypercapnia Induced Vasodilation [PDF]

, 2014

Hypoxia, not pulmonary vascular pressure induces blood flow through intrapulmonary arteriovenous anastomoses [PDF]

, 2014
Blood flow through intrapulmonary arteriovenous anastomoses (IPAVA) is increased with exposure to acute hypoxia and has been associated with pulmonary artery systolic pressure (PASP).
