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? 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.
The speed of rotation of earth about its axis is 1670 km/hr or 0.4638889. While the speed of revolution of earth around the Sun is 107,000 km/hr or 30 km/s. Well, you can say that when Earth is alone it enjoys solitude, but when itâs around Sun itâs really in a haste. You can calculate these figures easily knowing these values: Circumference of the Earth at the Equator = 40,000 kilometers
