Population structure and evolution of non-O1/non-O139 Vibrio cholerae by multilocus sequence typing.

Pathogenic non-O1/non-O139 Vibrio cholerae strains can cause sporadic outbreaks of cholera worldwide. In this study, multilocus sequence typing (MLST) of seven housekeeping genes was applied to 55 non-O1/non-O139 isolates from clinical and environmental sources. Data from five published O1 isolates and 17 genomes were also included, giving a total of 77 isolates available for analysis.

Conjugated copolymers containing low bandgap rhenium(i) complexes.

Conjugated copolymers with novel low bandgap rhenium(I) complexes on the polymer main-chain are reported. The low bandgap metal-containing polymers were synthesized by Suzuki cross-coupling polycondensation or Stille coupling polymerization. The metal free copolymers are conjugatively-linked with functionalized intramolecular charge transfer units, which exhibited prominent absorption band in the UV-vis region.

Multilevel factor analysis and structural equation modeling of daily diary coping data: Modeling trait and state variation.

The current study used multilevel modeling of daily diary data to model within-person (state) and between-person (trait) components of coping variables. This application included the introduction of multilevel factor analysis (MFA) and a comparison of the predictive ability of these trait/state factors. Daily diary data was collected on a large (n = 366) multiethnic sample over the course of five days.

Daily stress and alcohol consumption: modeling between-person and within-person ethnic variation in coping behavior.

Objective: Using a daily diary approach, the current study evaluated the relationship between coping and alcohol consumption using a large, multiethnic sample. The primary goals of this study were to (a) identify coping strategies that are either protective or risk factors for alcohol consumption and (b) model between-ethnic and within-ethnic group variation for these relations.

Method: College students (N = 365, 69.

PAD4-dependent antibiosis contributes to the ssi2-conferred hyper-resistance to the green peach aphid.

Myzus persicae, commonly known as green peach aphid (GPA), is a sap-sucking insect with a broad host range. Arabidopsis thaliana responds to GPA infestation with elevated expression of the PHYTOALEXIN DEFICIENT4 (PAD4) gene. Previously, we had demonstrated that the loss of PAD4 gene function compromises Arabidopsis resistance to GPA.

Optically tunable intramolecular charge transfer dyes for vacuum deposited bulk heterojunction solar cells.

We present the tunability of the photophysical and electrochemical properties of a series of intramolecular charge transfer compounds by facile molecular design and synthesis. The photovoltaic performances based on these sublimable materials and C(60) bulk heterojunction cells are compared and reported. The structural modification of the charge transfer dyes altered not only the electronic properties, but also the morphology of the bulk heterojunction thin films, as revealed by AFM and SEM studies.
