Studies have confirmed exosomes' positive role in the mending of tendons and tendon-bone structures. This study methodically examines the existing literature, evaluating the effectiveness of exosomes in facilitating the healing of tendons and the tendon-bone interface. A systematic review of the literature, meticulously adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses, was executed on January 21, 2023. Among the electronic databases scrutinized were Medline (via PubMed), Web of Science, Embase, Scopus, Cochrane Library, and Ovid. In the culmination of the review process, a total of 1794 articles were considered systematically. Additionally, a snowball search was implemented. For the final analysis, forty-six studies were chosen, resulting in a dataset of 1481 rats, 416 mice, 330 rabbits, 48 dogs, and 12 sheep. Histological, biomechanical, and morphological benefits were observed in these studies, due to exosomes' role in accelerating tendon and tendon-bone healing. Some studies have proposed that exosomes participate in tendon and bone-tendon repair, primarily by (1) diminishing inflammatory responses and modulating the activation of macrophages; (2) altering gene expression patterns, adjusting the cell microenvironment, and reorganizing the extracellular matrix; and (3) fostering angiogenesis. The risk of bias was found to be low, in the aggregate, for the studies considered. Preclinical research, encompassed in this systematic review, showcases the positive effects of exosomes on the healing of tendons and tendon-bone interfaces. The ambiguity surrounding the risk of bias underscores the critical need for standardized outcome reporting. The most suitable exosome source, methods of isolation, concentration procedures, and administration frequency are yet to be discovered. Furthermore, a limited number of investigations have employed large animals as research subjects. Further studies are likely needed to compare the safety and effectiveness of varying treatment parameters in large animal models, thereby aiding in the design of robust clinical trials.
The research sought to determine the microhardness, mass changes after a one-year water immersion, water sorption/solubility, and calcium phosphate precipitation behavior of experimental composites that incorporated 5-40 wt% of two types of bioactive glass (45S5 or a custom low-sodium fluoride formulation). The procedure involved evaluating Vickers microhardness after simulated aging processes (water storage and thermocycling), water sorption and solubility measurements in accordance with ISO 4049, and finally, calcium phosphate precipitation examinations, carried out through the combined use of scanning electron microscopy, energy-dispersive X-ray spectroscopy, and Fourier-transform infrared spectroscopy. Increasing the proportion of BG in composites composed of BG 45S5 resulted in a considerable reduction in their microhardness. Conversely, a 5 wt% concentration of customized BG exhibited microhardness statistically equivalent to the control material, whereas 20 wt% and 40 wt% BG concentrations led to a substantial enhancement in microhardness. Water sorption displayed a more pronounced effect in composites incorporating BG 45S5, escalating seven times compared to the control, while the customized BG composite exhibited a two-fold increase. Solubility escalated with greater BG concentrations, demonstrating a sudden surge at 20 wt% and 40 wt% BG 45S5. The presence of 10 wt% or more BG in all composites led to the precipitation of calcium phosphate. The customized BG-functionalized composites exhibit improved mechanical, chemical, and dimensional stability, maintaining the potential for calcium phosphate precipitation.
This investigation sought to assess the effects of various surface treatments (machined; sandblasted, large grit, and acid-etched (SLA); hydrophilic; and hydrophobic) on the morphology, roughness, and biofilm development of dental titanium (Ti) implant surfaces. Four groups of Ti disks underwent different surface treatments, namely femtosecond and nanosecond laser applications for achieving hydrophilic and hydrophobic characteristics. Surface morphology, wettability, and roughness were scrutinized. Colony counts for Aggregatibacter actinomycetemcomitans (Aa), Porphyromonas gingivalis (Pg), and Prevotella intermedia (Pi) served as a metric for evaluating biofilm formation at time points of 48 and 72 hours. A statistical assessment of the groups was conducted via the Kruskal-Wallis H test and the Wilcoxon signed-rank test, ultimately demonstrating significance at 0.005. The analysis of surface contact angle and roughness revealed a superior result for the hydrophobic group (p < 0.005), in contrast to the machined group, where significantly greater bacterial counts were observed across all biofilm types (p < 0.005). For Aa at 48 hours, the lowest bacterial counts were observed in the SLA group, whereas Pg and Pi saw the lowest counts in both the SLA and hydrophobic groups. At the 72-hour stage, the bacterial population densities in the SLA, hydrophilic, and hydrophobic sections were markedly low. The results confirm that a variety of surface treatments influence implant characteristics. The hydrophobic surface, treated with femtosecond laser technology, showcases a particularly pronounced suppression of initial biofilm formation (Pg and Pi).
Naturally occurring plant polyphenols, tannins, display a wide array of promising biological activities, including potent antibacterial effects, leading to their consideration for pharmacological applications. Our earlier research showcased the antibacterial efficacy of sumac tannin, the chemical structure of which is 36-bis-O-di-O-galloyl-12,4-tri-O-galloyl-D-glucose, isolated from Rhus typhina L., across various bacterial strains. The pharmacological potency of tannins hinges significantly on their capacity to engage with biomembranes, potentially facilitating cellular entry or surface-level activity. The current work was geared toward the study of sumac tannin's interactions with liposomes, a simplified model of cellular membranes, with the intention of elucidating the physicochemical characteristics of molecule-membrane interactions. These lipid nanovesicles are often targeted as nanocarriers to transport a diverse range of biologically active molecules, including antibiotics. Differential scanning calorimetry, zeta-potential, and fluorescence analyses were employed to demonstrate the powerful interaction of 36-bis-O-di-O-galloyl-12,4-tri-O-galloyl,D-glucose with liposomes, leading to its incorporation and encapsulation. Significantly superior antibacterial activity was observed in the formulated sumac-liposome hybrid nanocomplex, in comparison with pure tannin. Leech H medicinalis Nanobiomaterials possessing strong antibacterial action against Gram-positive bacterial strains, such as Staphylococcus aureus, Staphylococcus epidermidis, and Bacillus cereus, can be created using the high affinity of sumac tannin for liposomes.
