BBR affects macrophage polarization via inhibition of NF-κB pathway to protect against T2DM-associated periodontitis.

Background And Objective: Periodontitis is intimately associated with the development of various systemic diseases, among which type 2 diabetes mellitus (T2DM) has a bidirectional relationship with the pathogenesis of periodontitis. The objective of the present work was to investigate the role of berberine (BBR) in periodontitis with T2DM and related mechanisms.

Methods: The mRNA expression of macrophage polarization-related factors in the microenvironment of periodontal inflammation was detected using real-time quantitative PCR (RT-qPCR).

Arrestin beta-2 deficiency exacerbates periodontal inflammation by mediating activating transcription factor 6 activation and abnormal remodelling of the extracellular matrix.

Aim: To investigate the specific role of arrestin beta-2 (ARRB2) in the progression of periodontitis and the underlying mechanisms.

Materials And Methods: Single-cell RNA sequencing data were used to analyse gene expression in periodontal tissues from healthy controls and patients with periodontitis. Real-time quantitative polymerase chain reaction, Western blotting and immunohistochemical staining were performed to detect the expression of ARRB2.

Impact of transcranial direct current stimulation combined with motor-cognitive intervention on post-stroke cognitive impairment.

Objective: In this study, it was explored whether the efficacy on applying transcranial direct current stimulation (tDCS) combined with motor-cognitive intervention for post-stroke cognitive impairment (PSCI) was greater than that on applying each method alone.

Methods: A total of 90 patients with PSCI admitted to Zhejiang Provincial People's Hospital, China, from April 2021 to June 2022 were randomly divided into a tDCS group (n = 30), a motor-cognitive intervention group (n = 30), and a combination group (n = 30). All three groups received conventional rehabilitation therapy.

High expression of aryl hydrocarbon receptor (AhR) plays an important role in the formation of fibrous epulis.

Objectives: Epulis is considered to be a massive reactive lesion rather than a true neoplasia. AhR is thought to be associated with inflammation and development of neoplasms. Here, we aimed to observe the expression of AhR in fibrous epulis and explore its role and possible mechanism in the pathogenesis of epulis.

Porphyromonas gingivalis facilitated the foam cell formation via lysosomal integral membrane protein 2 (LIMP2).

Objective: The involvement of lysosomal integral membrane protein 2 (LIMP2) in cholesterol transport and formation of foam cells under the infection of Porphyromonas gingivalis (P. gingivalis) is yet to be elucidated. The current study verified the role and explored the mechanism of LIMP2 in promoting foam cell formation by P.

Formation of Human Periodontal Ligament Cell Spheroids on Chitosan Films.

Periodontal ligament (PDL) cells hold great promise for periodontal tissue regeneration. Conventionally, PDL cells are cultured on two-dimensional (2D) substrates such as tissue culture polystyrene (TCPS). However, characteristic changes of PDL cells have been observed during in vitro culture.

Adsorption of tricresyl phosphate onto graphene nanomaterials from aqueous solution.

Phosphorus flame retardant tricresyl phosphate (TCP) adsorption on graphene nanomaterials from aqueous solutions was explored using batch and column modes. Comparative studies were performed regarding the kinetics and equilibrium of TCP adsorption on graphene oxide (GO) and graphene (G) in batch mode. The adsorption kinetics exhibited a rapid TCP uptake, and experimental data were well described by the pseudo-second-order kinetic model.

Synthesis of graphene oxide-SiO2 coated mesh film and its properties on oil-water separation and antibacterial activity.

Oil-water separation has recently become a worldwide challenge due to the frequent occurrence of oil spill accidents and increasing industrial oily wastewater. In this work, the multifunctional mesh films with underwater oleophobicity and certain bacteriostatic effects are prepared by layer-by-layer assembly of graphene oxide-silica coatings on stainless steel mesh. The mesh film exhibits excellent environmental stability under a series of harsh conditions.
