OBJECTIVE Previous studies have shown the importance of somatic mutations and arginine residues in the complementarity-determining regions (CDRs) of pathogenic anti-double-stranded DNA (anti-dsDNA) antibodies in human and murine lupus, and in studies of murine antibodies, a role of mutations at position 53 in V(H) CDR2 has been demonstrated. We previously demonstrated in vitro expression and mu...

The joint use of multi-frequency signals brings new prospects for precise positioning and has become a trend in Global Navigation Satellite System (GNSS) development. However, a new type of inter-frequency clock bias (IFCB), namely the difference between satellite clocks computed with different ionospheric-free carrier phase combinations, was noticed. Consequently, the B1/B3 precise point posit...

BACKGROUND Cytokinesis occurs just as chromosomes complete segregation and reform nuclei. It has been proposed that cyclin/Cdk kinase inhibits cytokinesis until exit from mitosis; however, the timer of cytokinesis has not been experimentally defined. Whereas expression of a stable version of Drosophila cyclin B blocks cytokinesis along with numerous events of mitotic exit, stable cyclin B3 allo...

We present key elements of a proof of a strong form of Arnold diffusion for systems of three and a half degrees of freedom. More exactly, let T3 be a 3-dimensional torus and B3 be the unit ball around the origin in R3. Fix ρ > 0. Our main result says that for a “generic” time-periodic perturbation of an integrable system of three degrees of freedom H0(p) + εH1(θ, p, t), θ ∈ T3, p ∈ B3, t ∈ T = ...

application of bio-fertilizers, especially mycorrhiza as substituent or complement of chemical fertilizers is one of the most important strategies for plant nutrition in sustainable management of agro-ecosystems. in order to evaluate the separated and integrated application of mycorrhiza biological fertilizer and phosphorus chemical fertilizers on growth indices of chickpea (cicer arietinum l.)...

PURPOSE This study was undertaken to investigate whether thioltransferase (TTase) exhibits dehydroascorbate (DHA) reductase activity in human lens epithelial cells. METHODS TTase was investigated for DHA reductase activity in vitro by the method of glutathione reductase-coupled spectrophotometric assay. DHA reductase activities of human lens epithelial (HLE-B3) cell lysate and TTase-depleted ...

We have cloned cDNAs for Caenorhabditis elegans cyclins A1, B and B3. While cyclins A1 and B are most closely related to either A- or B-type cyclins of other species, cyclin B3 is less related to these cyclins. However, this cyclin is most similar to the recently identified chicken cyclin B3. Our identification of a Caenorhabditis homolog demonstrates that cyclin B3 has been conserved in evolut...

The B low Mr subunits of glutenin of the F2 generation from three durum wheat crosses were analysed. Three new alleles were found at three different loci: Glu-A3i coding for 5C20 subunits, Glu-B2c coding for subunit 12* and Glu-B3l coding for 1C3C13*C16 subunits. The genetic distances between Glu-A3-Gli-A1, Glu-B2-Gli-B1, Glu-B3-Glu-B2 and Glu-B3-Gli-B1 were calculated. The effects of the allel...

A new monoclonal antibody Ki-B3 produced by a fusion with leukemic cells of a centroblastic/centrocytic lymphoma (m.l. follicular) is introduced. This antibody predominantly recognizes B cells of follicular mantle and germinal center cells, as well as plasma cells in normal lymphoid tissue. Furthermore, 80% of all low- and high-grade B cell lymphomas are stained, whereas among T cell lymphomas,...
