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.
Topic Overview. Sepsis is an extreme immune system response to an infection that has spread throughout the blood and tissues. Severe sepsis, also called septic shock, often causes extremely low blood pressure, which limits blood flow to the body and can result in organ failure and death.epsis is most often the result of a bacterial infection, but it can also be caused by other types of infection. Sepsis can occur in people of any age, but it is more common in infants, older adults, and people who have compromised immune systems.
