An Achromobacter xylosoxidans strain from the Tripoli central hospital produced a unique metallo-β-lactamase, designated TMB-1, which is related to DIM-1 (62%) and GIM-1 (51%). bla(TMB-1) was embedded in a class 1 integron and located on the chromosome. The TMB-1 β-lactamase has lower k(cat) values than both DIM-1 and GIM-1 with cephalosporins and carbapenems. The K(m) values were more similar ...

The rank+nullity theorem states that, if T is a linear transformation from a finite-dimensional vector space V to a finite-dimensional vector space W , then dim(V ) = rank(T ) + nullity(T ), where rank(T ) = dim(im(T )) and nullity(T ) = dim(ker(T )). The proof treated here is standard; see, for example, [14]: take a basis A of ker(T ) and extend it to a basis B of V , and then show that dim(im...

We consider embeddings of the complete t-ary trees of depth k (denotation T k,t) as subgraphs into the hypercube of minimum dimension n. This n, denoted by dim(T k,t), is known if max{k, t} ≤ 2. First we study the next open case max{k, t} = 3. We improve the known upper bound dim(T k,3) ≤ 2k + 1 up to limk→∞ dim(T k,3)/k ≤ 5/3 and derive the asymptotic limt→∞ dim(T 3,t)/t = 227/120. As a co-res...

We present a new regularization method, for d dim (Euclidean) quantum field theories in the continuum formalism, based on the domain wall configuration in (1+d) dim space-time. It is inspired by the recent progress in the chiral fermions on lattice. The wall ”height” is given by 1/M , where M is a regularization mass parameter and appears as a (1+d) dim Dirac fermion mass. The present approach ...

Supersymmetric gauge theories of certain class possess a large hidden nonperturbative symmetry described by the Ding-Iohara-Miki (DIM) algebra which can be used to compute their partition functions and correlators very efficiently. We lift DIM-algebraic approach developed study holomorphic blocks 3d linear quiver one dimension higher. employ an algebraic construction in underlying trigonometric...

BACKGROUND Aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor associated with gastric carcinogenesis. 3,3'-Diindolylmethane (DIM) is a relatively non-toxic selective AhR modulator. This study was to detect the effects of DIM on gastric cancer cell growth. METHODS Gastric cancer cell SGC7901 was treated with DIM at different concentrations (0,10,20,30,40,50 μmol/L) with...

1,1-Bis(3'-indoly)-1-(p-substituted phenyl)methanes (C-DIM) exhibit structure-dependent activation of peroxisome proliferator-activated receptor gamma and nerve growth factor-induced Balpha (Nur77) and induce receptor-dependent and receptor-independent apoptosis in cancer cells and tumors. In this study, we investigated the activation of apoptosis in pancreatic cancer cells by p-bromo (DIM-C-pP...

Heterochromatin and associated gene silencing processes play roles in development, genome defense, and chromosome function. In many species, constitutive heterochromatin is decorated with histone H3 tri-methylated at lysine 9 (H3K9me3) and cytosine methylation. In Neurospora crassa, a five-protein complex, DCDC, catalyzes H3K9 methylation, which then directs DNA methylation. Here, we identify a...
