Mediating Effect of Self-Efficacy on the Relationship Between Perceived Social Support and Resilience in Patients with Recurrent Schizophrenia in China.

Purpose: To explore the mediating effect of self-efficacy on the relationship between perceived social support and resilience in patients with recurrent schizophrenia in China.

Patients And Methods: In this cross-sectional study, a total of 176 patients with recurrent schizophrenia who were hospitalized in a tertiary hospital in Hunan Province, China, completed a general data questionnaire, the Connor Davidson Resilience Scale (CD-RISC), the Perceived Social Support Scale (PSSS) and the General Self-Efficacy Energy Scale (GSES).

Results: Among the 176 patients, the mean GSES score was 2.

Transcriptomic analysis of two Beauveria bassiana strains grown on cuticle extracts of the silkworm uncovers their different metabolic response at early infection stage.

Beauveria bassiana is an important entomopathogenic fungus which not only widely distributes in the environment but also shows phenotypic diversity. However, the mechanism of pathogenic differences among natural B. bassiana strains has not been revealed at transcriptome-wide level.

The red pigment prodigiosin is not an essential virulence factor in entomopathogenic Serratia marcescens.

Although pigments produced by pathogenic microbes are generally hypothesized as essential virulence factors, the role of red pigment prodigiosin in the pathogenesis of entomopathogenic Serratia marcescens is not clear. In this study, we analyzed the pathogenicity of different pigmented S. marcescens strains and their non-pigmented mutants in silkworms.

Antiviral activity and specific modes of action of bacterial prodigiosin against Bombyx mori nucleopolyhedrovirus in vitro.

Prodigiosin, the tripyrrole red pigment, is a bacterial secondary metabolite with multiple bioactivities; however, the antiviral activity has not been reported yet. In the present study, we found the antiviral activity of bacterial prodigiosin on Bombyx mori nucleopolyhedrovirus (BmNPV)-infected cells in vitro, with specific modes of action. Prodigiosin at nontoxic concentrations selectively killed virus-infected cells, inhibited viral gene transcription, especially viral early gene ie-1, and prevented virus-mediated membrane fusion.
