AIMS/HYPOTHESIS: The aims of the present work were to identify plasma metabolites that predict future type 2 diabetes, to investigate the changes in identified metabolites among individuals who later did or did not develop type 2 diabetes over time, and to assess the extent to which inclusion of predictive metabolites could improve risk prediction. METHODS: We established a nested case-control study within the Swedish prospective population-based Västerbotten Intervention Programme cohort...

A novel aerobic, Gram-stain-positive, sporogenous, rod-shaped bacterial strain, 7578-1T, was isolated from ripened Pu'er tea. Based on 16S rRNA gene sequence similarity comparisons, strain 7578-1T was grouped into the genus Bacillus and appeared to be closely related to the type strains Bacillus shackletoniiLMG 18435T (98.4 %), Bacillus acidicolaDSM 14745T (97.6 %), Bacillus paralicheniformis KACC 18426T (97.2 %) and Bacillus ginsengihumi KCTC 13944T (96.7 %). The fatty acid profile containing the major fatty acids, iso-C15 : 0, anteiso-C15 : 0 and anteiso-C17 : 0 supported the allocation of strain 7578-1T to the genus Bacillus...

A taxonomic study was conducted on BR7-21T, a bacterial strain isolated from the soil of a ginseng field in Baekdu Mountain. Comparative studies of the 16S rRNA gene sequence showed that the isolate was most closely related to Conexibacter woesei DSM 14684T, Solirubrobacter pauli ATCC BAA-492T, Patulibacter minatonensis JCM 12834T, with 93.8%, 92.4%, and 91.5% sequence similarity, respectively; each genus represented a family in the order Solirubrobacterales. Strain BR7-21T was Gram-reaction positive, non-spore forming, aerobic, non-motile, and short rod-shaped...

A Gram-stain-positive, alkaliphilic bacterium, designated EGI 80668T, was isolated from a Tamarix cone soil in Xinjiang, north-west China. Cells were facultatively anaerobic, terminal endospore-forming and motile by means of peritrichous flagella. Colonies were yellowish and the cells showed oxidase-negative and catalase-positive reactions. Strain EGI 80668T grew at pH 8.0-10.0 and with 0-10 % (w/v) NaCl (optimally at pH 9.0 and with 1-2 % NaCl) on marine agar 2216. The predominant menaquinone was MK-7...

Despite its high relevance, developmental neurotoxicity (DNT) is one of the least studied forms of toxicity. Current guidelines for DNT testing are based on in vivo testing and they require extensive resources. Transcriptomic approaches using relevant in vitro models have been suggested as a useful tool for identifying possible DNT-generating compounds. In this study, we performed whole genome microarray analysis on the murine progenitor cell line C17.2 following 5 and 10 days of differentiation. We identified 30 genes that are strongly associated with neural differentiation...

The development of a covalent inhibitor of 17β-hydroxysteroid dehydrogenase type 1 (17β-HSD1) is a promising approach for the treatment of hormone-dependent breast cancer and endometriosis. After reporting the steroid derivative PBRM as a first potent covalent inhibitor of 17β-HSD1 without estrogenic activity, we are now interested in studying its pharmaceutical behavior. The metabolism study in a human liver microsomal preparation showed a gradual transformation of PBRM into PBRM-O, an oxidized ketonic form of PBRM at position C17...

A strictly anaerobic bacterial strain (FH042T) was isolated from a methanogenic reactor treating waste from cattle farms. Cells were stained Gram-positive, straight to gently curved rods with polar flagella. The strain was asaccharolytic. The strain fermented amino acids (l-arginine, l-lysine and l-serine) as growth substrates and produced acetate and butyrate. The optimum temperature for growth was 30 °C and the optimum pH was 6.1-6.8. Oxidase, catalase and nitrate-reducing activities were negative. Hydrogen sulfide was produced...

BNN27, a C17-spiroepoxy derivative of DHEA, was shown to have anti-apoptotic properties via mechanisms involving the NGF receptors (TrkA/ p75NTR). In this study we examined the effects of BNN27 on neural/glial cell function, apoptosis and inflammation in the experimental rat streptozotocin (STZ)-model of diabetic retinopathy (DR). The ability of BNN27 to activate the TrkA receptor and regulate p75NTR expression was investigated. BNN27 (2,10,50mg/kg,7days,i.p.) administration four weeks post STZ-injection (Paradigm A) reversed the diabetes-induced glial activation, loss of function of amacrine cells (bNOS/TH expression) and ganglion cell axons via a TrkAR-dependent mechanism...

A novel endophytic actinomycete strain, designated KM-1-2T, was isolated from seeds of Ginkgo biloba at Yangling, China. A polyphasic approach was used to study the taxonomy of strain KM-1-2T and it was found to show a range of phylogenetic and chemotaxonomic properties consistent with those of members of the genus Streptomyces. The diamino acid of the cell wall peptidoglycan was identified as LL-diaminopimelic acid. No diagnostic sugars were detected in whole cell hydrolysates. The predominant menaquinones were identified as MK-9(H6) and MK-9(H8)...

BACKGROUND: Congenital infection of Toxoplasma gondii is an important factor causing birth defects. The neural stem cells (NSCs) are found to be one of the target cells for the parasite during development of the brain. As a key virulence factor of the parasite that hijacks host cellular functions, ROP18 has been demonstrated to mediate the inhibition of host innate and adaptive immune responses through specific binding different host immunity related molecules. However, its pathogenic actions in NSCs remain elusive...

Strain Eup a-8(T), isolated from a torch coral Euphyllia glabrescens, was characterized using a polyphasic taxonomy approach. Cells of strain Eup a-8(T) were Gram-staining-negative, aerobic, motile by means of a single polar flagellum, poly-β-hydroxybutyrate-containing, rod-shaped and formed white colonies. Optimal growth occurred at 25-30 °C, pH 7-8, and in the presence of 2 % NaCl. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain Eup a-8(T) belonged to the genus Thalassotalea and showed the highest levels of sequence similarity with respect to Thalassotalea ganghwensis JC2041(T) (97...

A Gram-stain-positive strain, designated DT7-02(T), was isolated from the surface-sterilized root of Oenotherabiennis (evening primrose) and subjected to taxonomic characterization. Cells of DT7-02(T) were slender rod-shaped, motile by means of flagella, and oxidase- and catalase-positive. The colonies were circular, pinkish-yellow, opaque, glistering and 1-2 mm in diameter. The strain was moderately thermophilic and halophilic, as growth occurred at 20-44 °C (optimum 40 °C), pH 7-10 (optimum pH 8-9) and in the presence of 0-8 % of NaCl (optimum 4 %) in tryptic soy broth...

Two psychrotolerant facultative anaerobes, strains B7-2(T) and B5(T), were isolated from the Zoige Wetland on the Qinghai-Tibetan Plateau. The 16S rRNA gene sequences of strains B7-2(T) and B5(T) shared high similarity (>99 %) with those of the type strains of the genus Trichococcus, while their digital DNA-DNA hybridization values with each other (49 %) and with the reference type strains (48-23 %) were lower than 70 %, which suggest that they represent two novel species of the genus Trichococcus...
