J Anaesthesiol Clin Pharmacol
. 2023 Feb;
38(4):580-587.
PMID: 36778814
Background And Aims: Anesthesia often reduces mean arterial pressure (MAP) to a level that may compromise cerebral blood flow. We evaluated whether phenylephrine treatment of anesthesia-induced hypotension affects internal carotid...

PMID: 35552407
Context: The Arg16 variant in the β2-receptor gene is associated with increased risk of severe hypoglycemia in subjects with type 1 diabetes mellitus. Objective: We hypothesized that the Arg16 variant...

Eur J Anaesthesiol
. 2020 Mar;
37(6):482-490.
PMID: 32175988
Background: Anaesthesia reduces mean arterial pressure (MAP), and to preserve organ perfusion, vasopressors are often used to maintain MAP above 60 mmHg. Cognitive dysfunction is common following major surgery and...

. 2019 Mar;
39(4):255-260.
PMID: 30897269
Ageing reduces cerebral blood flow (CBF), while mean arterial pressure (MAP) becomes elevated. According to 'the selfish brain' hypothesis of hypertension, a reduction in vertebral artery blood flow (VA) leads...

J Appl Physiol (1985)
. 2018 Jul;
125(4):1080-1089.
PMID: 29975605
Studies of the resting brain measurements of cerebral blood flow (CBF) show large interindividual and regional variability, but the metabolic basis of this variability is not fully established. The aim...

PMID: 29504258
The effect of recombinant erythropoietin (rhEPO) on renal and systemic hemodynamics was evaluated in a randomized double-blinded, cross-over study. Sixteen healthy subjects were tested with placebo, or low-dose rhEPO for...

PMID: 27632347
Background: Gly16arg polymorphism of the adrenergic β2-receptor is associated with the elevated cardiac output (Q) in healthy gly16-homozygotic subjects. We questioned whether this polymorphism also affects Q and regional cerebral...

PMID: 26924722
Background: Erythropoietin (EPO) is produced in the liver during fetal life, but after birth the production shifts to the kidneys. The liver maintains a production capacity of 10% of the...
