Resuscitation PlusAim: To determine whether targeting mild hypercapnia (PaCO2 7 kPa) would yield improved cerebral blood flow and metabolism compared to normocapnia (PaCO2 5 kPa) with and without targeted temperature management to 33 °C (TTM33) in a porcine post-cardiac ...

Ventilation in conscious dogs during acute and chronic hypercapnia
, 1976 Minute ventilation was measured in conscious dogs, at rest and during exercise (1 mph), over 60 min immediately following the acute inhalation of 5% carbon dioxide in air and at 2, 4, 7, and 14 days while breathing the same gas mixture in a chamber. The

Comparative Genomics and Functional Evidence for Convergent Adaptation to Hypoxia in Mammals
Integrative Zoology, EarlyView.This study reveals convergent selection in mammals adapted to hypoxia. Functional assays demonstrate that amino acid mutations reduce oxidative stress, attenuate hypoxia‐induced injury, and modulate the hypoxia‐inducible transcription factor (HIF)‐driven hypoxic response.

Young and middle‐aged mouse breathing behavior during the light and dark cycles
Physiological Reports, 2019 Unrestrained barometric plethysmography is a common method used for characterizing breathing patterns in small animals. One source of variation between unrestrained barometric plethysmography studies is the segment of baseline.

Vascular responses of choroid plexus during hypercapnia in rats
, 1991 The response of blood flow to choroid plexus (CPBF) during hypercapnia is controversial. The goal of this study was to determine the effect of hypercapnia on CPBF in unanesthetized rats.

MRI BRAIN lesions and growth after antenatal steroids in preterm infants: Does timing matter?
Acta Obstetricia et Gynecologica Scandinavica, EarlyView.Timing matters: antenatal corticosteroids reduce brain injury in very low birth weight infants, but their protective effect in extremely preterm neonates declines when birth occurs beyond 7 days from administration. Abstract Introduction Antenatal corticosteroids (ACS) are widely used to improve outcomes in preterm infants, with known benefits on ...

The influence of carotid disease on cerebral vascular autoregulation and cerebral vascular reactivity to hypercapnia [PDF]
, 1995 Cerebral vascular reactivity to hypercapnia, assessed using transcranial Doppler ultrasonography of middle cerebral artery blood flow velocity, is used to assess the extent of cerebral blood flow reserve.
