This will trigger a haemodynamic and metabolic response to preserve the cerebral metabolic rate of oxygen (CMRO2). Cerebral auto-regulation will dilate resistance arteries to maintain adequate cerebral blood flow, (decreasing the cerebrovascular reserve capacity (CVR) in affected vascular regions) and an increase in oxygen ...
More and more scientific evidence shows that reactive oxygen species (ROS) and reactive nitrogen species are important mediators of signaling events in cells, especially the superoxide anion in reactive oxygen species. ...
It is responsible for the majority of patient deaths whilst in adult intensive care (ICUs) as multiple organ failure develops from sepsis and septic shock, where blood pressure drops dramatically and denies oxygen to vital organs. Low to middle income countries are more heavily affected, with one in ten deaths arising from pregnancy and childbirth thought to be a direct result ...
Joint tissues (synovial membranes) swell up, there is disturbance in blood circulation and local tissues become anoxic (lacking in oxygen), thus slowing down cell metabolism. Hypoxia (oxygen deprival) is central to the effects of rheumatoid arthritis, as blood flow to the joint is decreased because of intra-articular pressure and the inflamed ...
Using DNA microarray and quantitative reverse transcription-PCR (RT-PCR) analyses, we found that sigB disruption led to reduced transcript levels of genes involved in the metabolism of glucose into organic acids. This in turn resulted in retardation of glucose consumption by cells under conditions of oxygen deprivation. These results indicate that SigB is ...
The exergy source comes from the direct and diffuse solar radiation absorbed in the leaves, while exergy destruction occurs as the consequence of evapotranspiration, of internal flows and of leaf metabolism. Exergy storage occurs namely in the form of glucose which is a result of photosynthesis and oxygen release into the environment. Based on the exergy balance ...
