Two Gram-stain-negative, curved-rod-shaped, non-motile and aerobic bacteria W6 and I13 were isolated from marine sediment samples collected from Meishan Island located in the East China Sea. Catalase and oxidase activities and hydrolysis of Tween 40, 60 and 80 were positive for both strains, while nitrate reduction, indole production, methyl red reaction and HS production were negative. Phylogenetic analyses based on 16S rRNA and genome sequences revealed that strains W6 and I13 formed distinct phylogenetic lineages within the genera and , respectively.

To explore the effects of salt-tolerance gene accumulation on salt tolerance in transgenic plant, we used four types of plant expression vector (N27, N28, N29, and N30) carrying mtlD, mtlD + gutD, mtlD + gutD + BADH, mtlD + gutD + BADH + sacB genes respectively, to transform tobacco through Agrobacterium-mediated method. Transgenic lines were identified through polymerase chain reaction (PCR) detection. Transgenic lines and non-transgenic plant (CK) were subjected to 6‰ sodium chloride solution stress; then, fluorescence quantitative PCR (FQ-PCR) and salt tolerance indexes were used to assess characteristics.

Objectives: Rheumatoid arthritis (RA) is a chronic, destructive autoimmune disorder predominantly targeting the joints, with gut microbiota dysbiosis being intricately associated with its progression. The aim of the present study was to develop of effective early diagnostic methods for early RA based on gut microbiota.
Methods: A cohort comprising 262 RA patients and 475 healthy controls (HCs) was recruited.

ConspectusThe discovery of reversible hydrogenation using metal-free phosphoborate species in 2006 marked the official advent of frustrated Lewis pair (FLP) chemistry. This breakthrough revolutionized homogeneous catalysis approaches and paved the way for innovative catalytic strategies. The unique reactivity of FLPs is attributed to the Lewis base (LB) and Lewis acid (LA) sites either in spatial separation or in equilibrium, which actively react with molecules.

Two-dimensional (2D) materials are highly valued for their unique properties and potential applications, as they can display exotic behaviors differing from those of their bulk forms. Research on elementary and binary solids has been making great progress recently, while synthesizing multi-component 2D materials experimentally remains a challenge, despite the possibility of greatly extending the number of members of the 2D realm. In this study, we synthesized ternary BiTeX (X = Cl, Br, I) nanosheets with high crystallinity through an electrochemical exfoliation method.
