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?

Centripetal acceleration = 0.03392 meters per second squared. The acceleration of gravity on Earthâs surface is about 9.8 meters per second squared, so the acceleration due to Earthâs rotation on its axis, as found above, is by comparison quite small.
