Candida spp. can form biofilms on mucosal surfaces and epithelial cells as well as on devices implanted in the body such as catheters and dentures, which are thought to underlie the most recalcitrant infections. It was aimed to show antifungal and antibiofilm activities of oregano oil (Origanum onites). The antifungal activities of some essential oils were investigated against C. spp. and among them, oregano oil was found to be the most effective oil and further biofilm studies were conducted with it. Oregano oil inhibited biofilm adhesion and formation of C. spp. and mature biofilms and also displayed the ability to reduce biofilm formation when they were allowed to form on surfaces previously coated with oil (up to 50% inhibition rates). In addition, oregano oil was found to be effective against dual biofilms of Candida albicans + Staphyloccocus aureus at different concentrations. This study suggests that O. onites essential oil has useful antibiofilm effects against C. spp. The inhibitory effects of O. onites essential oil, against C. spp., were demonstrated for the first time. It also had antifungal effect on biofilm formation and established biofilm even at MIC level. Telescopic implant-retained overdentures are considered one of the most common treatment modalities for edentulous patients. The aim of the study was to evaluate the retention of a BioHPP (biocompatible highperformance polymer) telescopic overdenture supported by customized abutments made from 2 different materials after the simulation of 1 year in function. Twelve models of a completely edentulous mandible were three-dimensionally (3D)-printed. Two implants and 2 groups of customized abutments - group Bio BioHPP (n = 6) and group Ti titanium (n = 6) - were used to support BioHPP telescopic overdentures. A vertically dislodging force was applied to each denture until its separation before and after 240,000 cycles of chewing simulation and 1,440 iterations of cyclic dislodgement for the simulation of 1 year in function in order to measure maximum tensile loads needed to dislodge the overdenture. Student's t test and the paired t test were used for the statistical analysis (α = 0.05). The initial and final retentive forces of the Ti group were significantly higher than in the case of the Bio group. A significant decrease in the retentive forces within the 2 groups after chewing simulation was observed and it was higher in group Ti; however, there was no statistically significant difference between the 2 groups. The retentive force values for implant-retained telescopic overdentures significantly decreased after the simulation of 1 year of overdenture use. Both BioHPP and titanium are considered suitable abutment materials to retain telescopic overdentures. The retentive force values for implant-retained telescopic overdentures significantly decreased after the simulation of 1 year of overdenture use. Both BioHPP and titanium are considered suitable abutment materials to retain telescopic overdentures. Keloid is a unique refractory syndrome characterized by a proliferation disorder of the fibroblasts. Recently, photodynamic therapy (PDT) has become a promising technique to modulate fibroblasts. However, use of the photosensitizer Phenalen-1-one (Ph1) in PDT for keloid remains to be explored. This study investigated the efficacy of Ph1-PDT in the in vitro and in vivo models of keloid. Cell viability was assessed with a Cell Counting Kit-8 (CCK-8) analysis in keloid fibroblasts. The migrated and invaded keloid fibroblasts after Ph1-PDT were detected using scratch and matrigel invasion assays in vitro. Flow cytometry measured the apoptosis changes. The protein concentrations and the mRNA expression of inflammatory modulators (interleukin 8 (IL-8) and IL-1β) were determined using enzyme-linked immunosorbent assay (ELISA) and real-time quantitative polymerase chain reaction (RT-qPCR) methods, respectively. Nude mice were used to perform the transplantation of keloid grafts. Western blot analysis measured tting fibroblast apoptosis, suggesting a potential therapy method for keloid. Excessive proliferation and migration of vascular smooth muscle cells (VSMCs) are associated with the pathogenesis of atherosclerosis (AS). Eplerenone (EPL), a novel selective aldosterone receptor blocker, plays a substantial role in the treatment of cardiovascular disease. The G protein-coupled estrogen receptor (GPER) is a target of EPL as the STITCH website predicated. We aimed to investigate the roles of EPL in AS and identify its potential mechanisms of action. Oxidized low-density lipoprotein (ox-LDL) was employed to stimulate VSMCs to establish a cellular model of AS. The ability of cell proliferation was examined using a Cell Counting Kit-8, and the expression of proliferation-related proteins was tested using immunofluorescence staining and western blot analysis. Subsequently, cell migration and the expression of migration-associated proteins were evaluated with a wound healing assay, transwell assay and western blot analysis. Then, GPER expression was determined using western blot analysis in the absence or presence of EPL. To explore the regulatory mechanisms of EPL in ox-LDL-stimulated VSMCs, GPER was overexpressed, followed by measurement of cell proliferation and migration. The Ox-LDL stimulation notably upregulated GPER expression, whereas EPL treatment downregulated GPER expression in a dose-dependent manner. https://www.selleckchem.com/products/mycmi-6.html Additionally, EPL markedly inhibited proliferation and migration of VSMCs, and the highest dose of EPL resulted in the most marked effect. By contrast, GPER overexpression reversed the inhibitory effects of EPL on proliferation and migration of VSMCs. Eplerenone suppressed ox-LDL-induced proliferation and migration of VSMCs partly through downregulation of GPER, providing a new mechanism of support for EPL use in the clinical treatment of AS. Eplerenone suppressed ox-LDL-induced proliferation and migration of VSMCs partly through downregulation of GPER, providing a new mechanism of support for EPL use in the clinical treatment of AS.Compared with inorganic thermoelectric materials, organic thermoelectric (OTE) materials have attracted increasing attention due to their advantages of low toxicity, high mechanical flexibility, and large-scale solution processability. In the past few years, OTE materials have made remarkable progress in terms of their design, synthesis, and device performance. However, some challenges remain, including the low doping efficiency in n-type materials, poor doping stability with molecular dopants, and the largely reduced Seebeck coefficient after heavily doping, etc. All these factors hinder the further development of OTEs for commercial applications. In this Minireview, we highlight several key challenges during the development of OTEs and summarize recent understandings and efforts to address these challenges.
