It is well-known that B2 is an inverse 0-simple semigroup that has played a distinguished role in the theory of semigroups. Let B2 be the variety generated by B2, and let B0 be the variety generated by the subsemigroup B0 = {0, d, cd, dc} of B2. Since all semigroups with five or fewer elements are finitely based [5], the variety B2 and its subvariety B0 are finitely based. In fact, it has been ...

The b2 subunit of the Na,K-ATPase displays functional properties of both an integral constituent of an ion pump and an adhesion and neurite outgrowth-promoting molecule in vitro. To investigate whether the b1 subunit of the Na,K-ATPase can functionally substitute for the b2 isoform in vivo, we have generated b2/b1 knock-in mice by homologous recombination in embryonic stem cells. In b2/b1 knock...

OBJECTIVES The increasing prevalence of extended-spectrum β-lactamase (ESBL)-producing Escherichia coli has been associated with the emergence of the CTX-M-producing sequence type 131 (ST131) pandemic clonal group, a member of the O25b serogroup and the B2 phylogenetic group. To assess the clonal spread of ESBL-producing E. coli in Japan, a regional surveillance programme was conducted. METHO...

Twelve to twenty percent of newly synthesized poly(A) + RNA is transcribed by RNA polymerase III in Ehrlich ascites carcinoma and P3O1 plasmocytoma mouse tumors. Most of this RNA designated as pol IIIpoly(A) + RNA has a size of 160 to 800 nucleotides with a maximum of distribution of ca. 300 nucleotides. Pol IIIpoly(A) + RNA fraction consists of two major classes of molecules corresponding to p...

[3H8]Thromboxane B2 was biosynthesized and infused into an unanesthetized monkey. Several urinary metabolites were isolated and their structures elucidated using gas chromatography-mass spectrometry. In addition to the major urinary metabolite, dinor-thromboxane B2, a series of metabolites resulting from dehydrogenetion of the alcohol group at C-11 were identified: 11-dehydro-thromboxane B2, 11...

After infection with T. brucei AnTat 1.1, C57BL/6 mice lost splenic B2 B cells and lymphoid follicles, developed poor parasite-specific antibody responses, lost weight, became anemic and died with fulminating parasitemia within 35 days. In contrast, infected C57BL/6 mice lacking the cytotoxic granule pore-forming protein perforin (Prf1-/-) retained splenic B2 B cells and lymphoid follicles, dev...

The contents of total, free, and bound vitamin B2 (B2) in bovine milk and their distribution in four separate milk fractions, including milk during the early lactation stage, were estimated. The total B2 content in whole mature milk was 179 +/- 25 micrograms/100 g (n = 16), and its distribution in the cream, whey, skim milk membrane, and casein fractions was 6, 67, 9, and 18%, respectively. The...
