OBJECTIVE To assess the benefit of selecting blastocysts for cryotransfer based upon prior comparative genomic hybridization (CGH) karyotyping of blastomeres derived from their cleaved embryos of origin. Implantation and birth rates per transfer of previtrified CGH-tested blastocysts were compared with those following the transfer of nonCGH-tested fresh and(More)
This paper is the first in a series proposing to evaluate growth constants from the viewpoint of and by the methods of the physical chemist. After discussing the physicochemical conception of growth, tentative numerical values of two growth constants are given for several species of animals including man, and the methods of computation are discussed in(More)
The numerical values of the growth constants given in the preceding paper of this series are utilized for determining equivalence of growth age and growth weight in several animal forms. The results are presented in the form of two age-equivalence tables and fifteen age-equivalence and weight-equivalence charts.
An extensive amount of data is presented on the growth in weight of the dairy cow from 2 to 17 years of age, covering practically the entire duration of life. The data show that after the age of 2 years the rate of growth declines in a non-cyclic manner. The course of decline in growth follows the course of decline of a monomolecular chemical reaction; that(More)
Stability and regenerability of the absorption spectrum of CTAB solubilized rhodopsin at an air-water interface is studied. The spectral properties of rhodopsin films in the dark are stable more than 150 minutes. When rhodopsin is bleached (40 — 50%) and maintained in highly com­ pressed films recovery of the spectrum is observed. The recovery is 57% to(More)
The fluorescence lifetime of chlorophyll a gives information about the primary photo-physical events in photosynthesis. Most of the light energy absorbed by chlorophylls is utilized for photochemistry. There are two main additional pathways competing for the absorbed light energy: fluorescence and radiationless internal conversion (heat). Only a few percent(More)
Growth curves consist, in all cases, of two major segments. The first major segment is, in the case of higher animals and plants, made up in turn of several (probably five) shorter segments during each of which growth takes place at a constant percentage rate. The transitions between the successive stages are abrupt, the abruptness being of the order of(More)
