Cerebral Blood Volume Changes during Brain Activation [PDF]

Journal of Cerebral Blood Flow & Metabolism, 2012
Cerebral blood volume (CBV) changes significantly with brain activation, whether measured using positron emission tomography, functional magnetic resonance imaging (fMRI), or optical microscopy. If cerebral vessels are considered to be impermeable, the contents of the skull incompressible, and the skull itself inextensible, task- and hypercapnia ...

Influence of cerebral global ischemia-reperfusion on succinate dehydrogenase activity in neurons of different neocortical layers

Учёные записки Санкт-Петербургского государственного медицинского университета им. Акад. И.П. Павлова, 2014
The aim of the study was to investigate changes in activity of succinate dehydrogenase (SDH) in cytoplasm of neurons of different cortical layers in early and late reperfusion period after global cerebral ischemia in rats.

Cerebral oxygenation and bioelectrical activity in preterm infants during surfactant replacement therapy with porcine and bovine preparations

Archives of Medical Science, 2020
Introduction Surfactant replacement therapy (SRT) might cause acute changes in cerebral oxygenation and alteration of brain bioelectrical activity. Varying physiologic responses and clinical outcomes were observed when different surfactant preparations ...

Organoids in pediatric cancer research

FEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Dynamics of bioelectric activity of the rats’ cerebral cortex under stress condition with a use of gidazepamum

Vìsnik Dnìpropetrovsʹkogo Unìversitetu: Serìâ Bìologìâ, Ekologìâ, 2007
Influence of a stress-factor and day tranquilizer on parameters of bioelectric activity of the rats’ cerebral cortex has been studied. It has been found that stress considerably reduced the percentage of a power of bioelectric activity of the delta ...

Dehydration accelerates reductions in cerebral blood flow during prolonged exercise in the heat without compromising brain metabolism [PDF]

, 2015
Dehydration hastens the decline in cerebral blood flow (CBF) during incremental exercise, while the cerebral metabolic rate for oxygen (CMRO2) is preserved.

Pyruvate Dehydrogenase Activity in the Rat Cerebral Cortex following Cerebral Ischemia [PDF]

Journal of Cerebral Blood Flow & Metabolism, 1989
The effect of cerebral ischemia on the activity of pyruvate dehydrogenase (PDH) enzyme complex (PDHC) was investigated in homogenates of frozen rat cerebral cortex following 15 min of bilateral common carotid occlusion ischemia and following 15 min, 60 min, and 6 h of recirculation after 15 min of ischemia.

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.
