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.
The Signs, Symptoms, and Causes of Sepsis. Sepsis is a general term to used to characterize an immune system response to an infection. This means that a viral, fungal, or bacterial infection of the lungs (pneumonia), kidneys, bloodstream (bacteriemia), or abdomen can lead to sepsis. This potentially life-threatening condition is considered a medical emergency.
