Harjai G, Shanbhog R. Comparative in-vitro analysis of amniotic Fluid's efficacy in sustaining viability and regulating apoptosis of periodontal fibroblasts versus HBSS. Dent Traumatol 2024. [PMID: 39007433 DOI: 10.1111/edt.12980] [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: 03/28/2024] [Revised: 05/23/2024] [Accepted: 06/13/2024] [Indexed: 07/16/2024]
Abstract
BACKGROUND Tooth avulsion necessitates swift replantation, for which the preservation of periodontal ligament (PDL) cell viability is paramount. Various storage media have been explored, yet a comparison between amniotic fluid (AF) obtained at different gestational stages (amniocentesis and full-term) and HBSS is lacking. AIM This study aims to evaluate AF (amniocentesis and full-term) against HBSS in sustaining PDL cell viability and regulating apoptosis at different time points. MATERIAL AND METHODS Periodontal fibroblasts cultured in α-MEM were treated with 100% AF (amniocentesis), 100% AF (full-term), and HBSS, incubated for 1, 3, 24, and 48 h at 37°C, and assessed using the MTT assay for viability and AO/EB staining for apoptosis, which was analyzed via fluorescent microscopy after 24 h. Statistical analysis was conducted using one-way ANOVA, multivariate ANOVA, and post hoc Tukey's multiple comparison tests (p < .05). RESULTS Amniotic fluid (amniocentesis) exhibited the highest optical density (OD), which implies the highest cell viability across time intervals, followed by AF (full-term) and HBSS. While HBSS maintained PDL morphology, both AF groups showed altered morphology. No cell death was observed after 24 h. CONCLUSIONS Within the limitations of this study, both AF groups showed the potential to sustain PDL cell viability after 1, 3, 24, and 48 h of storage. However, further investigation is warranted regarding their suitability as storage media.

ACS OMEGA 2023; 8:43698-43707. [PMID: 38027358 PMCID: PMC10666248 DOI: 10.1021/acsomega.3c05371] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Revised: 10/10/2023] [Accepted: 10/19/2023] [Indexed: 12/01/2023]
Abstract
Cannabidiol (CBD) has significant therapeutic potential; nevertheless, its advance as an effective drug by the pharmaceutical business is hindered by its inherent characteristics, such as low bioavailability, low water solubility, and variable pharmacokinetic profiles. This research aimed to develop nanoliposomes using an easy and low-cost method to improve the hydrosolubility of CBD and achieve a controlled delivery of the active principle under relevant physiological conditions from the mouth to the intestine; the cytotoxic and antitumor activities were also evaluated. To achieve the objective, core-shell nanoliposomes based on CBD were synthesized in three easy steps and characterized in terms of shape, size, surface chemistry, thermal capacity, and surface charge density through transmission electron microscopy (TEM), dynamic light scattering (DLS), Fourier transform infrared (FTIR), thermogravimetric analysis (TGA), and potential charge (PZ), respectively. CBD-controlled delivery trials were carried out under simulated mouth-duodenal conditions and fitted to Korsmeyer-Peppas and Noyes-Whitney models to conclude about the pharmacokinetics of CBD from nano-CBD. Cytotoxicity studies on nonmalignant human keratinocytes (HaCaT) were carried out to evaluate its safety and the recommended consumption dose, and finally, the antiproliferative capacity of nano-CBD on human colon carcinoma cells (SW480) was determined as beginning proposal for cancer treatment. The characterization results verified the water solubility for the CBD nanoencapsulated, the core-shell structure, the size in the nanometric regime, and the presence of the synthesis components. The dissolution rate at duodenal conditions was higher than that in buccal and stomach environments, respectively, and this behavior was associated with the shell (lecithin) chemical structure, which destabilizes at pH above 7.2, allowing the release by non-Fickian diffusion of CBD as corroborated by the Korsmeyer-Peppas model. In vitro biological tests revealed the innocuousness and cyto-security of nano-CBD up to 1000 mg·L-1 when evaluated on HaCaT cells and concentrations higher than 1000 mg·L-1 showed antitumor activity against human colon carcinoma cells (SW480) taking the first step as a chemotherapeutic proposal. These results are unprecedented and propose a selective delivery system based on nano-CBD at low cost and that provides a new form of administration and chemo treatment.

Analysis of Pulp Tissue Viability and Cytotoxicity of Pulp Capping Agents. J Clin Med 2023; 12:jcm12020539. [PMID: 36675467 PMCID: PMC9861128 DOI: 10.3390/jcm12020539] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2022] [Revised: 12/23/2022] [Accepted: 01/07/2023] [Indexed: 01/11/2023] Open
Abstract
The present research study assessed the cell viability and cytotoxic effect of mineral tri-oxide aggregate (MTA), Tetric N-Bond Universal bonding agent, Theracal PT (pulpotomy treatment), and platelet-rich fibrin (PRF) as pulp capping agents on human dental pulp stem cells (hDPSCs). The cells were isolated from the pulp tissue of an extracted healthy permanent third molar. After four passages in Dulbecco’s Modified Eagle’s Medium, the primary cells were employed for the investigation. The test materials and untreated cells (negative control) were subjected to an Methylthiazol-diphenyl-tetrazolium (MTT) cytotoxicity assay and assessed at 24-, 48-, and 72-h intervals. The Wilcoxon matched-paired t-test and Kruskal−Wallis analysis of variance (ANOVA) test were applied (p < 0.05). PRF imparted the highest cell viability at 48 h (p < 0.001), followed by MTA, Theracal PT, and Tetric N-Bond. Similarly, PRF had the highest potential to enhance cell proliferation and differentiation (p < 0.001), followed by Theracal PT, MTA, and the bonding agent at the end of 24 h and 72 h, respectively. Finally, PRF sustained the viability of human primary dental pulp stem cells more effectively than Theracal PT and MTA; however, the application of a Tetric N-Bond as a pulp capping agent was ineffective.

Abstract
Dental pulp treatment is the least intrusive procedure currently available for preserving the vitality of the pulp. Several studies are underway to improve the bioactivity of pulp capping materials. Tideglusib isa potent anti-inflammatory, antioxidant, and a regenerative drug developed against Alzheimer’s disease and has been shown to be effective in the treatment of dental cavities. However, its bioactive properties encapsulated within the nanoparticles as a component of pulp capping material are largely unknown. In this study, tideglusib-loaded bioactive glass nanoparticles were synthesized (tideglusib-BgNPs) and mixed at various concentrations into the calcium silicate cement to testits physiomechanical and bioactivitiescompared with biodentine (control). The calcium silicate cement with 10wgt% tideglusib-BgNPs showed comparable physiomechanical properties to that of biodentine. Additionally, the assessment of cytotoxicity and bioactivity (cell proliferation, wound healing, and cell migration assays) showed increased bioactivity in terms of better wound healing, increased proliferation, and better migration of human dental pulp stem cells than biodentine. These findings suggest new opportunities to use tideglusib-BgNPs in pulp therapy.

The Effects of Add-on Therapy of Phyllanthus Emblica (Amla) on Laboratory Confirmed COVID-19 Cases: A Randomized, Double-blind, Controlled Trial. Complement Ther Med 2022; 65:102808. [PMID: 35093510 PMCID: PMC8799474 DOI: 10.1016/j.ctim.2022.102808] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2020] [Revised: 01/03/2022] [Accepted: 01/25/2022] [Indexed: 12/02/2022] Open
Abstract
Objective This randomized, double-blind, controlled trial (RCT) aimed to evaluate the effect of Phyllanthus Emblica (Amla) as an add-on therapy on COVID-19_ related biomarkers and clinical outcomes in COVID-19 patients. Methods In this RCT, sixty-one patients were randomly assigned into two arms [the intervention (n=31) and control arms (n=30)]. The effect of Amla on diagnostic Reverse-transcription Polymerase Chain Reaction (RT-PCR) test results between the first and the last days of the study, the length of stay (LOS) in hospital, the percentage of lung involvement on CT scans, changes in the clinical symptoms, and the laboratory markers were assessed. Results The two study groups had similar baseline demographics and characteristics in terms of medical history. The mean of LOS in the intervention arm (4.44 days) was significantly shorter than in the control arm (7.18 days, P < 0.001); RT-PCR results were not significantly different between the two arms (P = 0.07). All clinical variables decreased over time in the two groups (P < 0.001). However, the difference between the two groups in terms of fever (P = 0.004), severity of cough (P = 0.001), shortness of breath (P = 0.004), and myalgia (P = 0.005) were significant, but this intergroup comparison was not significant with regard to respiratory rate (P = 0.29), severity of chills (P = 0.06), sore throat (P = 0.22), and weakness (P = 0.12). Out of the eight evaluated para-clinical variables, three variables showed significant improvement in the intervention arm, including the mean increase in oxygen saturation (SpO2) level (P < 0.001), the reduction in the mean percentage of lung involvement on CT (P < 0.001), and the improvement in C-reactive protein test results (P < 0.001). Conclusion Organic herbal Amla tea cannot significantly affect the RT-PCR results and or degree of lung involvement. Nevertheless, it showed an ameliorative effect on the severity of clinical signs and CRP levels. Also, Amla tea may shorten the recovery times of symptoms and LOS in COVID-19 patients.
