Experimental Physiology, EarlyView.Abstract Stability in cerebral oxygen extraction fraction (OEF) is typically determined by alterations in cerebral blood flow (CBF). At rest, arterial partial pressure of carbon dioxide (PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_2}}}$) and OEF exhibit a strong inverse relationship owing to the powerful influence of PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_2}}}$

A Rare Diagnosis in A Pediatric Case Without Metabolic Alkalosis; Bartter Syndrome
Bagcilar Medical BulletinInherited salt-wasting tubulopathies include antenatal Bartter syndrome (BS), classical (tip 3) BS, and Gitelman syndrome. BS is an autosomal recessive inherited syndrome associated with impaired sodium and chloride reabsorption in the renal tubule.

A Case of Pseudo-Bartter Syndrome with Severe Metabolic Alkalosis
Turkish Journal of Nephrology, 2019 INTRODUCTION: The Pseudo-Bartter Syndrome, unlike the Bartter and Gitelman Syndromes, is characterized with metabolic alkalosis without a tubular defect.

Acid base status of prevalent peritoneal dialysis patients
Bulletin de la Dialyse à Domicile, 2018 Acid-base status of patients on peritoneal dialysis is influenced by multiple factors. Metabolic acidosis is a common feature of chronic renal failure and dialysis treatment provides alkali in the dialysate in order to maintain a normal acid-base balance.

Cerebrovascular regulation during heat stress
Experimental Physiology, EarlyView.Abstract Given that the brain is a highly metabolic organ and is enclosed by the skull, effective regulation of cerebral blood flow (CBF), not only for oxygen and nutrients supply but also as a means of convective heat exchange, is critical for preventing excessive elevations in brain temperature.

Brain strain: Blood flow and metabolism in environmental extremes
Experimental Physiology, EarlyView.Abstract This narrative review compares and contrasts the most commonly encountered environmental stressors on human cerebrovascular functioning. From high altitude and space, extreme apnoea, heat and cold stress, the impact of these stressors on the regulation of cerebral blood flow (CBF) and oxygen metabolism (CMRO2${\mathrm{CM}}{{\mathrm{R}}_ ...

VARIATIONS OF GLUCOSE 6-PHOSPHATE DEHYDROGENASE ACTIVITY IN VARIOUS TISSUES INDUCED BY METABOLIC ALKALOSIS, ACIDOSIS AND DIABETES [PDF]
Journal of Sciences, Islamic Republic of Iran, 1994 The effects of chronic metabolic acidosis, alkalosis and alloxan-induced ketoacidosis on G6PD activity of rat kidney, liver and erythrocytes were studied.

The Journal of Physiology, EarlyView.Abstract figure legend During 10 h exposures to normobaric hypoxia exposure there was a selective leftward shift in ventilatory response to hyperoxic hypercapnic rebreathing, but not the cerebrovascular response. The key findings are that the resetting of the central chemoreflex to lower PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_2}}}$ during early hypoxic ...
