Astrocyte glycogen and brain energy metabolism
Glia, 2007AbstractThe 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.

Brain lipogenesis and regulation of energy metabolism
Current Opinion in Clinical Nutrition and Metabolic Care, 2008To revise current available information related to the role of brain lipogenic pathways in the regulation of energy homeostasis.The 'classical' hypothalamic neuropeptide view of feeding regulation has been extensively reviewed and revised during the past few years.

Brain Endothelial Cells: Metabolic Flux and Energy Metabolism
2021The 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

Effect of aging on brain energy-metabolism
Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2002The aging process involves morphological and functional changes in cerebral vasculature and deterioration of mitochondrial number and function. Furthermore, slow oscillations of cerebral blood flow and oxidative metabolism occur in animals under different pathological conditions such as ischemia.

Metal, EMF, and Brain Energy Metabolism
Electromagnetic Biology and Medicine, 2009Some 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.

Ion Transport and Energy Metabolism in Brain
Neurological Research, 1981The kinetics of extracellular K+ activity was compared to the availability of energy in the cortex of rats and gerbils exposed to anoxia, hypoxia, spreading depression, and ischemia. A combined K+/DC surface electrode was used alone or together with a fiber optic light guide in various experiments.

Energy metabolism in developing brain cells
Canadian Journal of Physiology and Pharmacology, 1992During development different energy substrates are available to cells in brain in plentiful supply. The metabolic environment, which is dictated by the milk diet rich in fat, ensures that substrates in addition to glucose are available as fuels. Some substrates serve readily as primary fuels for respiration, whereas other substrates can serve other ...

[Energy metabolism in the brain].
Zeitschrift fur Gerontologie, 1985In this review of brain energy metabolism, the utilization of glucose as the sole energy source in the normal brain is described and presented in a schematic form. Important reactions concerned with the synthesis and degradation of the energy carrier in the cell, ATP, are also noted.
