Today most astronomers believe that quasars, radio galaxies and the centres of so-called active galaxies just are different views of more or less the same phenomenon: a black hole with energetic jets beaming out from two sides. When the beam is directed towards us we see the bright lighthouse of a quasar. When the orientation of the system is different we observe it as an active galaxy or a radio galaxy. This âunified modelâ has gained considerable support through a number of Hubble observational programs.
Sepsis is a complication of severe infection characterized by a systemic inflammatory response. Mortality rates from sepsis range between 25% to 30% for severe sepsis and 40% to 70% for septic shock. The clinical presentation of sepsis is highly variable depending on the etiology.
Sepsis is caused most commonly by bacteria in the bloodstream, a condition known as bacteremia (bak-tuh-REE-me-uh). These bacteria produce toxins * that provoke a response by the body's immune system. The effect of the toxins combined with the response of the immune system brings about the disease.
