The R engine was the Toyota engine used in the 1958 Toyota Crown, the first model to be exported to the United States. Road & Track was unimpressed with the engine on its introduction, noting that it idled quietly but was not capable of very high revolutions per minute.
A Transfusion transmitted infection (TTI) is a virus, parasite, or other potential pathogen that can be transmitted in donated blood through a transfusion to a recipient. The term is usually limited to known pathogens, but also sometimes includes agents such as Simian foamy virus which are not known to cause disease.he virus that causes AIDS is the best known of the transfusion-transmitted infections because of high-profile cases such as Ryan White, a hemophiliac who was infected through factor VIII, a blood-derived medicine used to treat the disease.
Hepatitis C is believed to be transmitted only by blood. However, unlike many other blood borne viruses (like HIV) virtually any source of blood or blood products seems to be capable of carrying the virus, even if the source is indirect-like a used razor, for example. This makes hepatitis C far more transmissible than most other blood borne viruses-including HIV. Many hepatitis C victims contracted the disease through blood transfusions in the 1970s and 1980s. Rates of post-transfusion hepatitis during this period were determined to have been between 8% and 10%.
