PURPOSE Polymorphisms within the promoter region of several matrix metalloproteinase (MMP) genes have been linked to alterations in the level of transcription. We hypothesized that an individual's MMP genotype and haplotype will influence breast tumor progression and help predict prognosis. EXPERIMENTAL DESIGN This study has evaluated the association between single-nucleotide polymorphisms (S...

In this work 2-O-α-D-glucopyranosyl-L-ascorbic acid (AA-2G) was synthesized by Cyclodextrin glucanotransferase (CGTase) from Bacillus sp. SK 13.002 with L-ascorbic acid (AA) as an acceptor and maltose as a glycosyl donor. AA-2G production was analyzed by HPLC and was confirmed by LC/MS results. The reaction parameters, such as pH (4.0-9.0), temperature (25-50°C), time (0-30 h), substrate ratios...

First-principles calculation predict that olivine Li4MnFeCoNiP4O16 has ferrotoroidic characteristic and ferrimagnetic configuration with magnetic moment of 1.56μB per formula unit. The ferrotoroidicity of this material makes it a potential candidate for magnetoelectric materials . Based on the orbital-resolved density of states for the transtion-metal ions in Li4MnFeCoNiP4O16, the spin configur...

The 4A11 antigen is a unique cytokine-inducible antigen up-regulated on rheumatoid arthritis synovial endothelium compared with normal endothelium. In soluble form, this antigen, Lewisy-6/H-5-2 (Ley/H), or its glucose analog, 2-fucosyllactose (H-2g), mediates angiogenesis. The Ley/H antigen is structurally related to the soluble E-selectin ligand, sialyl Lewisx, and is selectively expressed in ...

The moduli space Sg of smooth spin curves parameterizes pairs [C, η], where [C] ∈ Mg is a curve of genus g and η ∈ Pic(C) is a theta-characteristic. The finite forgetful map π : Sg → Mg has degree 22g and Sg is a disjoint union of two connected components S+ g and S− g of relative degrees 2g−1(2g +1) and 2g−1(2g − 1) corresponding to even and odd theta-characteristics respectively. A compactifi...

One of the most interesting UMTS networks features is their integration with the 2G networks that provides seamless Endto-End services. Current widely deployed 2G and 3G networks provide InterRAT (Inter Radio Access Technology) mechanisms enabling interoperability between them in a manner that is almost transparent to the subscriber. These enable maximum benefit from 3G services while ensuring ...

Let L be a very ample line bundle on a smooth curve C of genus g with 3g+3 2 < degL ≤ 2g − 5. Then L is normally generated if degL > max{2g+2−4h(C,L), 2g− g−1 6 −2h(C,L)}. Let C be a triple covering of genus p curve C′ with C φ → C′ and D a divisor on C′ with 4p < degD < g−1 6 − 2p. Then KC(−φ ∗D) becomes a very ample line bundle which is normally generated. As an application, we characterize s...
