[PMID: 37777935 DOI: 10.1016/j.adaj.2023.08.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2023] [Revised: 08/07/2023] [Accepted: 08/10/2023] [Indexed: 10/02/2023]
Abstract
BACKGROUND Local anesthesia is an essential component of dentistry, but there is limited quantifiable understanding of what techniques and local anesthetic solutions are used by practicing dentists. Use of the local anesthetic articaine has been highly debated in dentistry regarding its efficacy and risks for paresthesia. The aims of this study were to expand the knowledge of local anesthesia practices of dentists in the United States through a large-scale survey and associate potential influencing factors regarding articaine use specifically. METHODS The 23-item survey was sent to 10,340 practicing dentists in the United States, gathering demographic data and local anesthesia approaches and concerns. Statistical analysis consisted of descriptive, bivariate, and multivariate logistic regression analyses. RESULTS A total of 1,128 dentists completed the survey. Previous experience with articaine was reported by 97.6% of respondents, with 3.3% no longer using articaine. Sixty percent of respondents indicated using articaine for most local anesthetic injections administered. Multivariable regression analysis found those reporting to use articaine for all local anesthetic injections involving vasoconstrictors were more likely to be male (odds ratio, 1.59; P = .002) or general dentists (odds ratio, 1.63; P < .001). CONCLUSIONS Articaine has a perceived benefit to practitioners as most respondents reported using articaine as their primary local anesthetic. A practitioner's sex and type were found to affect the profile of use of articaine. PRACTICAL IMPLICATIONS Assembling evidenced-based local anesthesia practices would be beneficial to ensure US practitioners are more standardized in administering local anesthetics, particularly articaine, in the safest and most efficacious way.

Abstract
Decabromodiphenyl ethane (DBDPE), a novel brominated flame retardant, is becoming increasingly prevalent in environmental and biota samples. While DBDPE has been shown to cause various biological adverse effects, the molecular mechanism behind these effects is still unclear. In this research, zebrafish embryos were exposed to DBDPE (50-400 μg/L) until 120 h post fertilization (hpf). The results confirmed the neurotoxicity by increased average swimming speed, interfered neurotransmitter contents, and transcription of neurodevelopment-related genes in zebrafish larvae. Metabolomics analysis revealed changes of metabolites primarily involved in glycolipid metabolism, oxidative phosphorylation, and oxidative stress, which were validated through the alterations of multiple biomarkers at various levels. We further evaluated the mitochondrial performance upon DBDPE exposure and found inhibited mitochondrial oxidative respiration accompanied by decreased mitochondrial respiratory chain complex activities, mitochondrial membrane potential, and ATP contents. However, addition of nicotinamide riboside could effectively restore DBDPE-induced mitochondrial impairments and resultant neurotoxicity, oxidative stress as well as glycolipid metabolism in zebrafish larvae. Taken together, our data suggest that mitochondrial dysfunction was involved in DBDPE-induced toxicity, providing novel insight into the toxic mechanisms of DBDPE as well as other emerging pollutants.

UPLC-LTQ-Orbitrap-Based Cell Metabolomics and Network Pharmacology Analysis to Reveal the Potential Antiarthritic Effects of Pristimerin: In Vitro, In Silico and In Vivo Study. Metabolites 2022; 12:metabo12090839. [PMID: 36144243 PMCID: PMC9505172 DOI: 10.3390/metabo12090839] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2022] [Revised: 09/01/2022] [Accepted: 09/02/2022] [Indexed: 11/29/2022] Open
Abstract
Rheumatoid arthritis (RA) is characterized by systemic inflammation and synovial hyperplasia. Pristimerin, a natural triterpenoid isolated from plants belonging to the Celastraceae and Hippocrateaceae families, has been reported to exhibit anti-inflammation and anti-proliferation activities. Our study aims to reveal the antiarthritic effects of pristimerin and explore its potential mechanism using in vitro, in silico, and in vivo methods. In the present study, pristimerin treatment led to a dose-dependent decrease in cell viability and migration in TNF-α stimulated human rheumatoid arthritis fibroblast-like synoviocytes MH7A. Moreover, UPLC-LTQ-Orbitrap-based cell metabolomics analysis demonstrated that phospholipid biosynthesis, fatty acid biosynthesis, glutathione metabolism and amino acid metabolic pathways were involved in TNF-α induced MH7A cells after pristimerin treatment. In addition, the adjuvant–induced arthritis (AIA) rat model was employed, and the results exhibited that pristimerin could effectively relieve arthritis symptoms and histopathological damage as well as reduce serum levels of TNF-α, NO and synovial expressions of p-Akt and p-Erk in AIA rats. Furthermore, network pharmacology analysis was performed to visualize crucial protein targets of pristimerin for RA treatment, which showed that the effects were mediated through the MAPK/Erk1/2, PI3K/Akt pathways and directing binding with TNF-α. Taken together, our study not only offered new insights into the biochemical mechanism of natural compounds for RA treatment, but also provided a strategy that integrated in vitro, in silico and in vivo studies to facilitate screening of new anti-RA drugs.
