Stress and foods are the main triggers for people with irritable bowel syndrome, or IBS, which can experience a bloated belly, flatulence, abdominal pain and cramps, constipation, diarrhea or alternating constipation and diarrhea. The trigger foods with IBS can vary from one person to another.
The first blood transfusion from animal to human was administered by Dr. Jean-Baptiste Denys, eminent physician to King Louis XIV of France, on June 15, 1667.ransfusions are used for various medical conditions to replace lost components of the blood. Early transfusions used whole blood, but modern medical practice commonly uses only components of the blood, such as red blood cells, white blood cells, plasma, clotting factors, and platelets.
The most well-known and medically important blood types are in the ABO group. They were discovered in 1900 and 1901 at the University of Vienna by Karl Landsteiner in the process of trying to learn why blood transfusions sometimes cause death and at other times save a patient.
