Effects of chronic hypercapnia on ammonium transport in the mouse kidney
Physiological Reports, 2019 Hypercapnia and subsequent respiratory acidosis are serious complications in many patients with respiratory disorders. The acute response to hypercapnia is buffering of H+ by hemoglobin and cellular proteins but this effect is limited.

Supporting patients with hypercapnia
Clinical MedicineHypercapnia is commonly encountered by general and specialist respiratory clinicians. Patients at risk of developing hypercapnic respiratory failure include those with chronic obstructive pulmonary disease (COPD), obesity and neuromuscular disease. Such patients may present to clinicians acutely unwell on the acute medical take or during an inpatient ...

Atropine does not attenuate cerebral vasodilatation during hypercapnia
, 1982 To study the contribution of cholinergic nerves to cerebral vasodilation during hypercapnia, we blocked muscarinic cholinergic receptors with atropine. We used two new approaches.

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.ABSTRACT Obstructive sleep apnea is a clinical syndrome that triggers a series of pathophysiologic changes, including disturbed sleep architecture, chronic intermittent hypoxia and hypercapnia, and ultimately severe cognitive dysfunction. The hippocampus plays a key role in various cognitive processes such as learning and memory.

Cardiovascular responses to severe hypercapnia of short duration
, 1964 Dogs under pentobarbital anesthesia were employed in an investigation of the effect of abrupt, severe hypercapnia upon blood pressure, heart rate, and force of myocardial contraction.

Corneal hypoxia and hypercapnia during contact lens wear
, 1990 Restriction of both oxygen influx to the cornea and carbon dioxide efflux from the cornea by contact lenses results in adverse tissue changes. We measured the extent of hypoxia and hypercapnia at the corneal surface of 10 human volunteers during static ...

Mean temperature determines whether winter variability accelerates or buffers energy loss
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Winter survival in dormant animals depends on conserving finite energy reserves, yet winter temperatures fluctuate around shifting means. In ectotherms, metabolic rate increases exponentially with temperature, so thermal variability is expected to accelerate energy loss,
