Energy metabolism in demented brain

Progress in Neuro-Psychopharmacology and Biological Psychiatry, 1986
The term dementia refers to a number of very complicated disorders of the brain with several morphological, biochemical and functional alterations. Several alterations occur in Alzheimer's disease. They include alteration in neurotransmitters related substances and changes in brain metabolic rate.

Brain Endothelial Cells: Metabolic Flux and Energy Metabolism

2021
The neurovascular unit (NVU) consists of multiple cell types including brain endothelial cells, pericytes, astrocytes, and neurons that function collectively to maintain homeostasis within the CNS microenvironment. As the principal barrier-forming component of the NVU, the endothelial cells perform an array of complex functions that require substantial

Energy metabolism of fish brain

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2002
This review focuses on recent research on the metabolic function of fish brain. Fish brain is isolated from the systemic circulation by a blood-brain barrier that allows the transport of glucose, monocarboxylates and amino acids. The limited information available in fishes suggests that oxidation of exogenous glucose and oxidative phosphorylation ...

Ketogenic Medium Chain Triglycerides Increase Brain Energy Metabolism in Alzheimer’s Disease

Journal of Alzheimer's Disease, 2018
Background: In Alzheimer’s disease (AD), it is unknown whether the brain can utilize additional ketones as fuel when they are derived from a medium chain triglyceride (MCT) supplement.

Brain Energy Metabolism in Hypoxemia

Scandinavian Journal of Clinical and Laboratory Investigation, 1972
The relationship of various levels of arterial and cerebral venous Po2to the cerebral energy state was evaluated in rats exposed to a lowering of the arterial Po2to 40, 30, and 20 mm Hg, respectively. The arterial Po2and cercbral venous Po2could be reduced down to 20 and 10 mm Hg, respectively, without major derangement of the cerebral energy state ...

Energy metabolism in the brain

2002
Publisher Summary The studies of glucose metabolism in the brain reflect a dichotomy because the complex integrating functions of the brain can only be studied in the intact, functioning brain in the conscious individual (human or animal). On the other hand, the properties of brain cells, cell-cell interactions, and mechanisms are most readily ...

Brain energy metabolism in global brain oedema

Acta Neurochirurgica, 1978
Different degrees of severity in global brain oedema were induced by varying amounts of water intoxication (50, 100, 150, and 200 ml Aqua dest./kg b.wt. intravenously) in groups of six cats, which were functionally nephrectomized. Animals loaded with physiological saline and sham-operated served as controls.

Compact energy metabolism model: Brain controlled energy supply

Journal of Theoretical Biology, 2010
The regulation of the energy metabolism is crucial to ensure the functionality of the entire organism. Deregulations may lead to severe pathologies such as obesity and type 2 diabetes mellitus. The decisive role of the brain as the active controller and heavy consumer in the complex whole body energy metabolism is the matter of recent research.

Metal, EMF, and Brain Energy Metabolism

Electromagnetic Biology and Medicine, 2009
Some implications of cooperative potential of metal ions and electromagnetic fields' radiation (EMF) in carcinogenic processes are discussed. It is known that these factors, chemical and physical individually have connections with processes of oxidative stress. Special attention was paid to possible manifestation within the brain.

Astrocyte glycogen and brain energy metabolism

Glia, 2007
AbstractThe brain contains glycogen but at low concentration compared with liver and muscle. In the adult brain, glycogen is found predominately in astrocytes. Astrocyte glycogen content is modulated by a number of factors including some neurotransmitters and ambient glucose concentration.
