Extended-spectrum β-lactamases (ESBLs) and AmpC β-lactamases produced by a clinical isolate of Klebsiella pneumoniae from chickens were detected with confirmatory phenotypic tests of the Clinical and Laboratory Standards Institute. The minimum inhibitory concentrations of 18 antibacterial drugs against K. pneumoniae were determined by the 2-fold microdilution method. The genotype and sub...

Consider the following problem: For given graphs G and F1, . . . , Fk, find a coloring of the edges of G with k colors such that G does not contain Fi in color i. For example, if every Fi is the path P3 on 3 vertices, then we are looking for a proper k-edge-coloring of G, i.e., a coloring of the edges of G with no pair of edges of the same color incident to the same vertex. Rödl and Ruciński st...

human interferon β (inf-β) is a member of cytokines family which different studies have shown its immunomodulatory and antiviral activities. in this study an expression vector was designed and constructed for expression of human inf-β-1b either in shake flasks and bench top bioreactor. the designed vector was constructed based upon pet-25b(+) with t7 promoter. recombinant human beta interferon ...

The least cardinal λ such that some (equivalently: every) compact group with weight α admits a dense, pseudocompact subgroup of cardinality λ is denoted by m(α). Clearly, m(α) ≤ 2. We show: Theorem 3.3. Among groups of cardinality γ, the group ⊕γQ serves as a “test space” for the availability of a pseudocompact group topology in this sense: If m(α) ≤ γ ≤ 2 then ⊕γQ admits a (necessarily connect...

Disrupted transforming growth factor- β (TGF-β) signaling is involved in the development of various types of cancer and the TGF-β receptor II (TGFBR2) is a key mediator of TGF-β growth inhibitory signals. It is reported that the G-875A polymorphism in TGFBR2 is implicated in risk of various cancers. However, results for the association between this polymorphism and cancer remain conflicting. To...

The families of TGF-β proteins are the most important growth factors in the ovary for growth and differentiation of early ovarian follicles. Three related oocyte-derived members of the transforming growth factor-β superfamily namely growth differentiation factor 9 (GDF9), BMP15 and BMPR-IB have been shown to be essential for follicular growth and ovulation. Different mutations in the GDF9 gene ...

the present study investigated the effects of prebiotic (α-mune), a mixture of mannan oligosaccharide, β-1,3 and β-1,6 glucan, on the growth performance, haematology and innate immunity of beluga sturgeon ( huso huso ) juvenile. fish (46±3 g) were allocated into 12 tanks (15 fish per tank) and triplicate groups were fed a control diet or diets containing 1.5, 3.0 and 4.5 g kg -1 prebiotic for 4...
