Notizen: Abstract Let P be a partially ordered set. Define k = k (P) = max p∈ |{x ∈ P : p 〈 x or p = x}|, i.e., every element is comparable with at most k others. Here it is proven that there exists a constant c (c 〈 50) such that dim P 〈 ck(log k)2. This improves an earlier result of Rödl and Trotter (dim P ≤2 k 2+2). Our proof is nonconstructive, depending in part on Lovász' local lemma.

Notizen: Abstract The individual contributions of the first two external domains of the HLA-B7 heavy chain to the expression of allele-specific (B7) and locus-specific (B and C) antigenic determinants were investigated using hybrid class I genes. Hybrid genes were constructed in vitro by exon shuffling between the parent genes HLA-B7, HLA-Cw3, HLA-A3, and H-2K d, and their expression was monitored following transfection into mouse L cells. The results show that most allele-specific antigenic determinants are associated with the first external domain of the 137 heavy chain, whereas all the locus-specific antigenic determinants tested map to the second external domain.

Notizen: Abstract Animal protein in broiler rations was replaced with Barseem Protein Concentrate (BPC). The standard group having blood, meat and fish meal as sources of animal protein showed an average weight gain of 1655 g. Replacement of blood meal with BPC resulted in a slight decrease in the average weight gain (1541 g) of broilers. Average weight gain of broilers increased to 1775 g and 1671 g when fish or meat meal was replaced with BPC in rations. Complete replacement of animal protein with BPC adversely affected growth and average weight gain decreased to 1443 g. Supplementation with lysine or methionine when animal protein was replaced with BPC did not improve growth of the broilers.
