The sera from patients with primary heart and skeletal muscle diseases, hospitalized patients without intrinsic muscle disease from an area endemic for Trypanosoma cruzi infections, and normal subjects (N = 693) were studied for the presence of immunoglobulin G (IgG) antisarcolemma activity using serologic methods.adioimmunoprecipitation showed a circulating antibody to a 25-kDa T. cruzi polypeptide (P25) in 16/17 (94.1%) patients with advanced cardiomyopathy and T. cruzi infection.
But how fast does the Earth rotate? You might be surprised to know that a spot on the surface of the Earth is moving at 1675 km/h or 465 meters/second.ut how fast does the Earth rotate?

In fact, the earth's speed at the North or South Pole is about one centimeter per 24 hour period. If you live midway between the poles and the equator (e.g. New York or Europe), the earth still spins fast, but not as fast as it does at the equator. Speeds for these locations are approximately 700 to 900 mph (1125 to 1450 kph).
