The bone turnover capability influences the acquisition and maintenance of osseointegration. The architectures of osteocyte three-dimensional (3D) networks determine the direction and activity of bone turnover through osteocyte intercellular crosstalk, which exchanges prostaglandins through gap junctions in response to mechanical loading. Titanium nanosurfaces with anisotropically patterned dense nanospikes promote the development of osteocyte lacunar-canalicular networks.

Background: Arg-gingipain A (RgpA) is the primary virulence factor of Porphyromonas gingivalis and contains hemagglutinin adhesin (HA), which helps bacteria adhere to cells and proteins. Hemagglutinin's functional domains include cleaved adhesin (CA), which acts as a hemagglutination and hemoglobin-binding actor. Here, we confirmed that the HA and CA genes are immunogenic, and using adjuvant chemokine to target dendritic cells (DCs) enhanced protective autoimmunity against P.

Objectives: This study aimed to explore the effect of pituitary tumor-transforming gene 1 (PTT-G1) on the invasion and proliferation of oral squamous cell carcinoma (OSCC) cell lines under the action of miR-362-3p.

Methods: The bioinformatics online database was used to query the expression of PTTG1 in head and neck squamous cell carcinoma (HNSCC). The expression of PTTG1 in the Cal-27, HN-30, and HOK cell lines was detected by Western blot.

The capability of embryogenic callus induction is a prerequisite for in vitro plant regeneration. However, embryogenic callus induction is strongly genotype-dependent, thus hindering the development of in vitro plant genetic engineering technology. In this study, to examine the genetic variation in embryogenic callus induction rate (CIR) in peanut ( L.

Protein -acyl transferases (PATs) catalyze -acylation, a reversible post-translational modification critical for membrane association, trafficking, and stability of substrate proteins. Many plant proteins are potentially -acylated but few have corresponding PATs identified. By using genomic editing, confocal imaging, pharmacological, genetic, and biochemical assays, we demonstrate that three Arabidopsis class C PATs positively regulate BR signaling through -acylation of BRASSINOSTEROID-SIGNALING KINASE1 (BSK1).

A micro-physiological system is generally fabricated using soft materials, such as polydimethylsiloxane silicone (PDMS), and seeks an inflammatory osteolysis model for osteoimmunological research as one of the development needs. Microenvironmental stiffness regulates various cellular functions via mechanotransduction. Controlling culture substrate stiffness may help spatially coordinate the supply of osteoclastogenesis-inducing factors from immortalized cell lines, such as mouse fibrosarcoma L929 cells, within the system.

Article Synopsis
  • The study aimed to understand what factors contribute to children's dental fear (CDF) and how it relates to resilience in 8-9 year olds in Weifang city, to inform prevention and intervention strategies.
  • A survey involving 1,995 children revealed a 31.78% prevalence rate of CDF, with higher rates found in girls and linked to factors like dental caries, pain, and past treatment experiences.
  • Findings suggest that children with greater psychological resilience and supportive parenting practices are less likely to experience CDF, emphasizing the importance of nurturing environments for children's dental health.

Silicon nitride (SN) with good osteoconductivity has been introduced as an implantable biomaterial for joint replacement and interbody fusion devices. In this study, SN was coated on a polyetheretherketone (PEEK) surface by inductively coupled plasma-enhanced chemical vapor deposition (ICPECVD). The results showed that a dense coating (thickness of about 500 nm) of amorphous SN was closely combined with a PEEK substrate (PKSN) with a binding strength of 6.
