Int J Biol Macromol 2024; 273:133065. [PMID: 38866273 DOI: 10.1016/j.ijbiomac.2024.133065] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2024] [Revised: 06/06/2024] [Accepted: 06/08/2024] [Indexed: 06/14/2024]
Abstract
Despite numerous advantages of liposomes in treating rheumatoid arthritis (RA), the in vivo stability remains a critical issue. Current strategies for improving liposomal stability often compromise their original properties. Herein, we designed an alginate nanogel-embedded liposome aiming at retaining those inherent advantages while enhancing their in vivo stability. The introduction of alginate network within the liposome core can provide mechanical support and controlled drug release without affecting the surface properties. Results showed the cross-linking of alginate network within the inner core of liposomes elevated the particle rigidity to 3 times, allowing for improved stability and decreased drug leakage. Moreover, this nanogel-embedded liposome with optimized elasticity obviously facilitated cellular uptake in inflammatory macrophages. When entering blood circulation, increased rigidity altered the composition of protein corona on the particle surface, resulting in 2-fold increase in circulation time and improved drug accumulation in arthritic joints. When anti-inflammatory chlorogenic acid (CA) was encapsulated into the nanogel network, this CA-loaded nanogel-embedded liposome significantly inhibited ROS production and inflammatory response, ultimately achieved superior therapeutic outcome in arthritic rats. Results demonstrated that this nanogel-embedded liposomes can essentially retain the inherent advantages and overcome the drawbacks of liposomes, thereby improving the drug delivery efficiency.

Evaluation of the Oral Health Conditions and Oral Health-Related Quality of Life in a Community-Dwellers Population Aged ≥ 45 Years in the Canton of Bern: A Preliminary Pilot Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:4557. [PMID: 36901566 PMCID: PMC10001686 DOI: 10.3390/ijerph20054557] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/08/2023] [Revised: 03/02/2023] [Accepted: 03/03/2023] [Indexed: 06/18/2023]
Abstract
OBJECTIVE To evaluate oral health conditions and oral health-related quality of life in community-dwellers aged ≥ 45 years in the Canton of Bern, Switzerland. MATERIALS AND METHODS One hundred subjects (63% males; mean age: 73 years), selected randomly using a cluster procedure within the Canton of Bern, underwent a clinical oral examination after completing questionnaires on socio-economic level, medical history, oral health behaviour, and Geriatric Oral Health Assessment Index (GOHAI). Descriptive analyses and multinomial regression models were applied to investigate the association between oral health diseases (dental caries and periodontitis) and specific participant characteristics. RESULTS The mean number of decayed, missing, and filled teeth (DMFT) was 0.30, 4.20, and 8.75, respectively; the mean DMFT score = 13.35. Dental caries prevalence (ICDAS > 0) was 15% and periodontitis prevalence was 46%. Logistic regression models revealed that living in an urban area was associated with lower odds (OR 0.03, 95%CI 0.00-0.36) of having periodontal disease. Male gender was associated with lower odds for dental caries (OR 0.31, 95%CI 0.09-1.01) and total lack of professional tooth cleaning was associated with higher odds for dental caries (OR 41.99, 95%CI 0.01-0.38). Ordinal logistic regression revealed that both the presence of dental caries (RR 12.80, 95%CI 1.47-111.20) and periodontal disease (RR 6.91, 95%CI 1.16-84.00) were statistically significantly associated with rheumatoid arthritis. CONCLUSION Within the study limitations, untreated dental caries and periodontal disease are prevalent in the Swiss population, despite the high level of self-performed oral hygiene and access to the dental care system.

Abstract
INTRODUCTION AND IMPORTANCE The aim of this article is to report the long-term outcome of full mouth rehabilitation with single piece, smooth surface implants following immediate loading protocol on a patient suffering with RA and severe unilateral condylar resorption. CASE PRESENTATION Here, we present a challenging case of a patient suffering from Rheumatoid Arthritis who was stabilized and completed successfully with a 4 year follow-up period. Prosthetic management optimized the inter-occlusal relationship to maintain both function and esthetic integrity. Single piece implants are designed to engage and take support from the cortical bone low in metabolic activities thus promoting the force transmission through apical threads that are engaged in the cortical bone. DISCUSSION Rheumatoid Arthritis [RA] is an auto-immune inflammatory condition in which the inflamed and hypertrophic synovial membrane grows into the articulation surfaces. The Temporomandibular Joints [TM] are frequently involved in rheumatoid arthritis. According to the literature on RA, due to frequent periodontitis, decreased salivary secretion, medication, as well as decrease in bone regenerative potential, RA is often considered as a relative contraindication in the use of implants. Atrophic jaws and cases with comorbidities like osteoporosis, diabetes, rheumatoid arthritis, periodontally infected cases are restored with high success by single piece smooth surface. CONCLUSION To the best of our knowledge, this may be the first case of immediate functional loading by bi-cortical single piece implants.

[PMID: 31661144 PMCID: PMC6854551 DOI: 10.3892/mmr.2019.10775] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2019] [Accepted: 07/17/2019] [Indexed: 12/20/2022] Open
Abstract
MicroRNAs serve an important role in the development of several diseases. Numerous genes regulate the skeletal muscle differentiation of C2C12 myoblasts. The role of miR-760 in rheumatoid arthritis (RA) has not been reported, to the best of our knowledge. Therefore, the aim of the present study was to examine the role of miR-760 in regulating skeletal muscle proliferation in RA. Potential genes functionally involved in the tarsal joint of a collagen-induced RA model were identified using Gene Expression Omnibus. Reverse transcription-quantitative PCR and western blot analyses were performed to determine the mRNA and protein expression levels. The proliferation, cell cycle progression and migration of C2C12 myoblasts were detected using Cell Counting Kit-8, flow cytometry and wound-healing assays, respectively. TargetScan was used to predict the potential target genes of miR-760, and this was verified using a dual-luciferase reporter assay. In the present study, myosin-18b (Myo18b) expression was determined to be downregulated in the RA model. Silencing Myo18b decreased the proliferation, abrogated the cell cycle progression, and reduced the migration and differentiation of C2C12 myoblasts. Expression levels of cyclin-dependent kinase 2, cyclin D1, matrix metalloproteinase (MMP)-2, MMP-9, myogenin and myosin heavy chain 6 were all decreased when Myo18b was silenced. Furthermore, overexpression of Myo18b induced opposing effects on C2C12 myoblasts. It was shown that Myo18b was a target gene of miRNA-760. Overexpression of miR-760 decreased proliferation, cell cycle progression, migration and differentiation in C2C12 myoblasts, and decreased the expression of Myo18b. The opposite results were observed when miR-760 was downregulated. In conclusion, miR-760 inhibited proliferation and differentiation by targeting Myo18b in C2C12 myoblasts. The results of the present study may contribute to understanding the mechanisms underlying RA skeletal muscle proliferation, and miR-760/Myo18b may serve as potential targets for treating patients with RA.

Abstract
Saliva is a multifaceted bodily fluid that is often taken for granted but is indispensable for oral health and overall well-being in humans. Although mainly comprised of water (99.5%), proteins, ions and enzymes turn saliva into a viscoelastic solution that performs a variety of vital tasks. This review article gives a brief overview of the salivary gland system, as well as the composition, output and functions of saliva. It also addresses the current applications of saliva for diagnostic purposes, the clinical relevance of saliva in oral diseases as well as current treatment options.
