Breast cancer: a critical review of a patient sample with a ten-year follow-up.

Records of 407 patients with primary breast cancer treated at the M.D. Anderson Hospital in 1958 and 1959 were reviewed with regard to patient characteristics, treatment, and results.

Ventricular performance and energy of compression, power, and rate of change of power during isovolumic contraction.

During isovolumic contraction, there is a calculabe compression of the blood within the ventricle. Energy is expended by the ventricle during isovolumic contraction, and some of it is transferred to the blood in the form of elastic compression. The rate of energy transfer (power) and acceleration of energy transfer (rate of change of power) during isovolumic contraction were calculated based upon considerations of the energy of compression.
