The metal-organic framework [Cd15(5MT)18(OH)4(SO4)4] (5-MT = 5-methyl-1H-tetrazole) with an unprecedented Cd(3)(micro3-OH)(micro3-SO4) core and two kinds of tetrazole coordination modes was formed by self-assembly and in situ synthesis of the 5-MT tetrazole ligand; the structure exhibits an unusual 3(9) x 4(12) x 5(15) topological network and shows reversible shrinkage and expansion in a crysta...
Cyclic division algebra (CDA) has recently become a major technique to construct nonvanishing determinant (NVD) space-time block codes. The CDA based construction method usually consists of two steps. The first step is to construct a degree-n cyclic extension over a base field and the second step is to find a non-norm algebraic integer in the base field. In this paper, we first propose a simple...
Normal human tissues and various human tumors were surveyed by immunohistochemical techniques for expression of the stage-specif ic embryonic antigen 1 (SSEA-1). The ant ibody reacted with many normal and neoplastic human tissues. In most instances, equivalent human and mouse tissues expressed SSEA-1 ; however, dif ferent t issue localization patterns were sometimes seen between these two speci...
The authors describe a case of histiocyte-rich B-cell lymphoma (HR-BCL), a variant of diffuse large B-cell lymphoma, in a 51-year-old man. The patient presented with large axillary lymphadenopathy. Histopathologic and immunohistochemical examination of lymph node biopsy revealed diffuse effacement of the lymph node architecture by reactive histiocytes and neoplastic CD20 positive B cells. ...
The lipopolysaccharide (LPS) of Helicobacter pylori expresses the Lewis x (Lex) and/or Ley antigen. We have shown previously that H. pylori LPS displays phase variation whereby an Lex-positive strain yields variants with different LPS serotypes, for example, Lex plus Ley or nonfucosylated polylactosamine. H. pylori has two alpha3-fucosyltransferase genes that both contain poly(C) tracts. We now...
