A tight coupling exists between synaptic activity and glucose utilization by astrocytes. Metabolic cooperation between neurons and astrocytes mediates this coupling. During synaptic activation, glutamate that is released in the synaptic cleft as a neurotra ...
Sulfurospirillum multivorans is an epsilonproteobacterium able to grow anaerobically with hydrogen as electron donor and tetrachloroethene (PCE) as terminal electron acceptor (organohalide respiration). The dechlorination is mediated by the PCE reductive d ...
Chloroethenes, and most particularly tetra- (PCE) and trichloroethene (TCE) are major groundwater pollutants due to their extensive industrial use as solvents since the 1920s. The strong electronegativity of the chlorines renders them very stable under aer ...
Glucose-evoked mitochondrial signals augment ATP synthesis in the pancreatic β cell. This activation of energy metabolism increases the cytosolic ATP/ADP ratio, which stimulates plasma membrane electrical activity and insulin granule exocytosis. We have re ...
The bioenergetics efficiency of aerobic respiration of an organism is expressed through P/O ratio, which represents the ATP production per oxygen atom reduced in Electron Transport Chains (ETC). P/O ratio, to date, has not been extensively used in the cont ...
Desulfitobacterium spp. are ubiquitous organisms with a broad metabolic versatility and some isolates have the ability to use tetrachloroethene (PCE) as terminal electron acceptor. In order to identify proteins involved in this organohalide respiration pro ...
Respiration is a fundamental catalytic process in the aerobic and anaerobic energy metabolism of many prokaryotic and most eukaryotic organisms. The major difference between these organisms is that various organic and inorganic substrates can be used to do ...
Diminished mitochondrial oxidative phosphorylation and aerobic capacity are associated with reduced longevity. We tested whether resveratrol (RSV), which is known to extend lifespan, impacts mitochondrial function and metabolic homeostasis. Treatment of mi ...
Groundwater contamination by organochloric compounds became a major concern for public health during the last century. Chloroethenes, commonly used since the 1920's as degreasing and cleaning agents and as intermediates in chemical synthesis, accumulated i ...
Deletion mutants with either deletion of HXK2 and REG1 of the wild-type strain Saccharomyces cerevisiae CEN.PK113-7D were quant. analyzed for the impact on carbon catabolite repression and the short-term effect of the oxidative metab. Therefore, continuous ...
