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?

Earth's rotation is slowing down, so it cannot be more than a few million years old. Pathlights, n.d. The age of the earth - 2. http://www.pathlights.com/ce_encyclopedia/05agee3.htm. The earth's rotation is slowing at a rate of about 0.005 seconds per year per year. This extrapolates to the earth having a fourteen-hour day 4.6 billion years ago, which is entirely possible. The rate at which the earth is slowing today is higher than average because the present rate of spin is in resonance with the back-and-forth movement of the oceans.
