Interaction between HLA-G and monocyte/macrophages in human pregnancy.

Several lines of evidence suggest that the human leukocyte antigen (HLA)-G play a key role in the regulation of human pregnancy. A sub-population of cells highly represented at the decidua belong to the myeloid-derived monocyte/macrophage lineage, which potentially interact with HLA-G expressing cells. It is proposed that HLA-G protects decidual trophoblasts from lysis by blocking the effector function of decidual monocyte/macrophages.

The use of extracellular enzymes from Streptomyces albus ATCC 3005 for the bleaching of eucalyptus kraft pulp.

The suitability of culture supernatant from Streptomyces albus ATCC 3005 for use in the biobleaching of eucalyptus kraft pulp was investigated. S. albus was found to grow on a minimal salts medium containing oat spelts xylan and yeast extract as the main carbon and nitrogen sources, respectively.
