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.
In addition to the rotational speed of the Earth spinning on its axis, the Earth is also speeding at about 66,660 miles per hour (107278.87 km/h) in its revolution around the sun once ever 365.2425 days.he Earth rotates on its axis once each day. Since the circumference of the Earth at the Equator is 24,901.55 miles, a spot on the Equator rotates at approximately 1037.5646 miles per hour (1037.5646 times 24 equals 24,901.55) (1669.8 km/h).
