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 can be defined as the bodyâs response to an infection. An infection is caused by microorganisms or âgermsâ (usually bacteria) invading the body, and can be limited to a particular body region (eg. open wound) or can be widespread in the bloodstream (often called âsepticemiaâ or âblood poisoningâ).epsis is a medical emergency just like a heart attack or stroke because there is an interruption of oxygen and nutrients to the tissues and vital organs such as the brain, intestines, liver, kidneys and lungs. At UCLA we place a strong importance on the early recognition and treatment of Sepsis.
