Astrocytes and energy metabolism
Archives of Physiology and Biochemistry, 2011Astrocytes are glial cells, which play a significant role in a number of processes, including the brain energy metabolism. Their anatomical position between blood vessels and neurons make them an interface for effective glucose uptake from blood. After entering astrocytes, glucose can be involved in different metabolic pathways, e.g.

Energy metabolism and cytotoxicity
Seminars in Nephrology, 2003Fatty acids constitute a major source of metabolic fuel for energy production in kidney tissue. During acute renal failure (ARF) injury to the proximal tubule and medullary thick ascending limb leads to structural and functional alterations that result in reduced expression and activity of mitochondrial and peroxisomal fatty acid oxidation (FAO ...

Physiological responses of a group of 16 tennis players have been investigated under the almost natural conditions of a 10 min long training match. Collecting the expired air into Douglas bags, transmitting heart rate all the time of experiment wirelessly and analysing every player's activity we have got following main results: The average intensity of

The heart must provide its own energy requirements to sustain its continuous contractile performance and other physiological functions. This chapter provides an integrated overview of cardiac energy metabolism in fish with a particular emphasis on: maintenance of cardiac energy state; biochemical strategies for energy production; and energetic ...

Medical Clinics of North America, 2000
Over the long-term, most adult humans are able to maintain body energy stores through the process of energy balance, which regulates how much energy is consumed to match how much energy is expended. Energy expenditure is required for resting metabolic rate to maintain basic physiologic functions (e.g., heart beat, muscle function, respiration) and ...

Energy metabolism inLeishmania
Journal of Bioenergetics and Biomembranes, 1994Alanine plays a key role in the response of promastigotes to osmotic stress and to hypoxia. It is rapidly released in response to hypo-osmolality, is consumed from its large intracellular pool under iso-osmotic conditions even in the presence of glucose, and is synthesized under hyperosmotic conditions even in the absence of glucose.

Exercise and Energy Metabolism
Pediatric Annals, 1984Most of the energy required for muscle contraction is generated by the splitting of ATP. Catabolism of carbohydrates to pyruvate and lactate by glycolysis (anaerobic) produces ATP needed during exercise of high intensity and short duration but the energy release is incomplete.

Microglia energy metabolism in metabolic disorder
Molecular and Cellular Endocrinology, 2016Microglia are the resident macrophages of the CNS, and are in charge of maintaining a healthy microenvironment to ensure neuronal survival. Microglia carry out a non-stop patrol of the CNS, make contact with neurons and look for abnormalities, all of which requires a vast amount of energy.

Energy Metabolism in the Liver
Comprehensive Physiology, 2014Abstract The liver is an essential metabolic organ, and its metabolic function is controlled by insulin and other metabolic hormones. Glucose is converted into pyruvate through glycolysis in the cytoplasm, and pyruvate is subsequently oxidized in the mitochondria to generate ATP through the TCA cycle and oxidative

Energy metabolism in the brain
2002Publisher 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 ...
