To compare the gene expression profiles and proliferation rates of fibroblasts from the oral lining and masticatory mucosae.

Primary human fibroblasts were retrieved from the posterior masticatory hard palate and the lining alveolar mucosa of five individuals. The gene expression profile was evaluated using total RNA sequencing. The proliferation rate was determined colorimetrically.

Substantial differences in specific gene groups and pathways were observed between fibroblasts from the two tissues. Significantly enriched gene ontology processes were focused on the extracellular components. Lining mucosa fibroblasts exhibited significantly higher expression of the principal structural collagens, cranial neural crest markers, and homeobox genes associated with positional memory. Masticatory mucosa fibroblasts showed greater expression of genes related to transforming growth factor-β signalling, which may be associated with fibrosis. In addition, they expressed higher levels of the EP
prostaglandin E
receptor and Toll-like receptor 1. Finally, masticatory mucosa fibroblasts exhibited a 10%-30% higher proliferation rate.

Fibroblasts from the lining and masticatory oral mucosae are phenotypically heterogeneous, presenting distinct gene expression profiles and proliferation rates. These features may contribute to their specific physiological functions and have relevance for potential therapeutic applications.

Cavotricuspid isthmus (CTI) ablation in typical atrial flutter (AFL) restores sinus rhythm in 95% of patients, which may lead to the discontinuation of oral anticoagulation during follow-up. Therefore, we aimed to systematically review the clinical impact of oral anticoagulation in the incidence of thromboembolic events (TE) after typical AFL ablation.

We searched for controlled studies evaluating the impact of anticoagulation in the incidence of TE in patients submitted to AFL ablation in MEDLINE, CENTRAL, PsycINFO database (June/2021). The primary outcome was TE events (ischemic stroke or systemic embolism). A meta-analysis was performed deriving risk ratios (RR) and 95% confidence intervals (CI). Statistical heterogeneity was measured through I
metric. The confidence in the evidence was appraised with Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework.

Eight observational studies with 4870 patients were included. TE events were not significantly reduced (RR 1.18, 95% CI 0.59-2.36; n=4870; GRADE very low). A meta-regression showed that for each 10% increase in the prevalence of previous AF in the studied population, anticoagulation reduced TE risk in 32%. There were no significant differences regarding bleeding events (RR 2.16, 95% CI 0.43-10.97, I
=0%; GRADE low), but there was a lower all-cause mortality (RR 0.24, 95% CI 0.17-0.32, GRADE low).

The best available evidence lacks robustness and the data did not definitely associate anticoagulation after typical AFL ablation with reduced TE.

To investigate whether halitosis is associated with impaired oral-health-related quality of life (OHRQoL).

This is a systematic review of the literature. Electronic searches were performed in PubMed via Medline, Web of Science, Scopus, and EMBASE up to and including June 2021. Observational studies that assessed halitosis in association with OHRQoL were included. The pooled standardized mean difference (SMD) was estimated by meta-analysis.

Thirteen studies were included in the review; however, the meta-analysis included only 10 studies, all cross-sectional, comprising 2692 individuals. The overall meta-analysis showed an association between halitosis and impaired OHRQoL (SMD 0.51; 95% confidence interval 0.27-0.75). Subgroup analyses, however, indicated that this association remained only among adults. Neither the OHRQoL instrument nor the halitosis assessment method, or the cultural background, influenced the pooled estimates. Meta-regression analyses revealed that the OHRQoL instrument, the halitosis assessment method, and the sample composition did not explain the between-study heterogeneity. Methodological quality appeared to explain 20% of the overall heterogeneity, as studies with high risk of bias overestimated the magnitude of the association.

Our findings suggest that halitosis is associated with impaired OHRQoL.

Lymphatic vessels are responsible for the removal of metabolic waste from body tissues. They also play a crucial role in skeletal muscle functioning thorough their high-energy metabolism. In this study we investigated whether disuse muscle atrophy induced by hindlimb unloading is associated with an alteration in the number of lymphatic vessels and differential expression of lymphangiogenic factors in the soleus muscle.

Male C57BL/6 mice were subjected to tail suspension (TS) for 2 or 4 weeks to induce soleus muscle atrophy. After TS, lymphatic and blood capillaries in the soleus muscle were visualized and counted by double staining with LYVE-1 and CD31. The protein and mRNA levels of vascular endothelial growth factor (VEGF)-C, VEGF-D, and vascular endothelial growth factor receptor-3 were measured by Western blotting and real-time reverse transcript polymerase chain reaction, respectively.

TS for 2 weeks resulted in a significant decrease in the number of blood capillaries compared with controls. However, there was no significant change in the number of lymphatic capillaries. By contrast, TS for 4 weeks resulted in a significant decrease in the number of lymphatic and blood capillaries. We observed a significant decrease in the mRNA levels of VEGF-C and VEGF-D in mice subjected to TS for 4 weeks.

The decrease of intramuscular lymphatic vessels may a crucial role in the process of muscle atrophy.

To identify the existing OHRQoL instruments for adults, describe their scope (generic or specific), theoretical background, validation type and cross-cultural adaptation.

A systematic search was conducted, and articles presenting validation of OHRQoL instruments in adults were included. Data were collected about the validation type external validation (correlations/associations); or internal validation (factor analysis/principal components analysis, item response theory); and cross-cultural adaptation.

Of 3730 references identified, 326 were included reporting 392 studies. Forty-two original instruments were found among 74 different versions, 40 generic and 34 condition-specific. Locker's theoretical framework was the predominant model. The oral health impact profile (OHIP) presented 20 versions, with OHIP-14 being the most frequent (26.8%), followed by geriatric oral assessment index (GOHAI) (14.0%), OHIP-49 (11.7%) and oral impacts on daily performances (OIDP) (9.7%). Most studies focused on external gorous internal validation process or have undergone cross-cultural adaptation. This, in turn, makes it difficult for researchers to choose an appropriate measure based on known psychometric properties. OHIP-14, OIDP and GOHAI seem to be the most widely validated instruments. Equalizing measurement properties for comparability are challenging due to theoretical heterogeneity. Future studies should assess psychometric properties, explore the factorial structure and work towards a consensus on critical issues.Nanopores have become a popular single-molecule manipulation and detection technology. In this paper, we have constructed a continuum model of the nanopore; the arbitrary Lagrangian-Eulerian (ALE) method is used to describe the motion of particles and fluid. The mathematical model couples the stress-strain equation for the dynamics of a deformable particle, the Poisson equation for the electric field, the Navier-Stokes equations for the flow field, and the Nernst-Planck equations for ionic transport. Based on the model, the mechanism of field-effect regulation of particles passing through a nanopore is investigated. The results show that the transport of particles which is controlled by the field effect depends on the electroosmotic flow (EOF) generated by the gate electrode in the nanopore and the electrostatic interaction between the nanopore and particles. That also explains the asymmetry of particle transport velocity in the nanopore with a gate electrode. When the gate potential is negative, or the gate electrode length is small, the maximum deformation of the particles is increased. The field-effect regulation in the nanopore provides an active and compatible method for nanopore detection, and provides a convenient method for the active control of the particle deformation in the nanopore.
To evaluate the salivary levels of myeloid-related markers in relation to periodontal disease and their potential screening capability, as well as the effects of periodontal treatment on these markers in periodontitis patients.

Participants with a healthy periodontium (n=60) and with gingivitis (n=63) and periodontitis (n=72) were recruited. Periodontitis patients received non-surgical treatment and were re-examined after 3 and 6months. Unstimulated saliva was collected at baseline and at 1, 3, and 6 months after therapy for the periodontitis patients. Levels of colony-stimulating factor-1 (CSF-1), interleukin-34 (IL-34), S100A8/A9, S100A12, hepatocyte growth factor (HGF), IL-1β, and matrix metalloproteinase-8 (MMP-8) were analysed by immunoassays.

CSF-1, S100A8/A9, S100A12, IL-1β, MMP-8, and HGF were significantly elevated in saliva from periodontitis and gingivitis patients in comparison to healthy individuals, whereas IL-34 was significantly lower in periodontitis compared to both healthy individuals and gingivitis patients. IL-34 increased significantly 3 months after treatment, while IL-1β and MMP-8 decreased 1 month after therapy. Additionally, periodontitis patients clustered in high and low levels of S100A8/A9, whereby those with high levels had more bleeding, deeper pockets, and higher S100A12.

Salivary levels of myeloid-related markers are altered in periodontitis and are partially modulated by periodontal treatment. Measuring S100A8/A9 in saliva may identify distinct groups of periodontitis patients.

This research aimed to identify the key compounds(s) and mechanism(s) of GL against AS through network pharmacology. learn more The compounds from GL were identified by gas chromatography-mass spectrum (GC-MS), and SwissADME screened their physicochemical properties. Then, the target(s) associated with the screened compound(s) or AS related targets were identified by public databases, and we selected the overlapping targets using a Venn diagram. The networks between overlapping targets and compounds were visualized, constructed, and analyzed by RStudio. Finally, we performed a molecular docking test (MDT) to explore key target(s), compound(s), on AutoDockVina. A total of 35 compounds in GL were detected via GC-MS, and 34 compounds (accepted by Lipinski's rule) were selected as drug-like compounds (DLCs). A total of 34 compounds were connected to the number of 785 targets, and DisGeNET and Online Mendelian Inheritance in Man (OMIM) identified 2,606 AS-related targets.
