Genotype by environment interaction for stayability of Red Angus in the United States.

Bulls are used across a wide variety of environments through the use of artificial insemination. However, not all bulls rank the same for genetic merit in all environments. Sire selection could be more accurate via improved methods of characterization.

Genotype by environment interactions for growth in Red Angus.

Accuracy of sire selection is limited by how well animals are characterized for their environment. The objective of this study was to evaluate the presence of genotype × environment interactions (G×E) for birth weight (BiW) and weaning weight (WW) for Red Angus in the United States. Adjusted weights were provided by the Red Angus Association of America.

Treatment of childhood acute immune thrombocytopenic purpura with anti-D immune globulin or pooled immune globulin.

Objective: To evaluate the effectiveness of initial treatment of children with acute immune thrombocytopenic purpura (ITP) with anti-D immune globulin (anti-D) or pooled IgG immune globulin (IVIg).

Study Design: The medical charts of 33 children diagnosed with acute ITP from May 1995 to October 1997 were reviewed. Patient data were eligible for analysis if, for the new diagnosis of acute ITP, the patient had received either anti-D at 45 to 50 microg/kg (WinRho SD, NABI) or IVIg at 0.
