In recent years, there has been growing interest in plant-derived products for their bioactive properties., Results and Conclusion. This study aimed to verify the effect of an herbal-food supplement, comprising alcoholic extracts of Epilobium, Urtica dioica and Evernia prunastri (YATROS, Etnopharma, Turin, Italy), alone or in combination with 5-Fluorouracil, on cell growth, DNA synthesis, cell-cycle profile, cytoskeleton reorganization and E-cadherin protein expression, in the murine colon carcinoma cell line C26. Assays used were respectively the Neutral Red uptake assay, median effect analysis, tritiated thymidine incorporation, flow cytometry, Phalloidin staining, and immunohistochemistry. A chemical fingerprint and multidimensional HPLC-UV-HRMS analysis was also performed on the herbal-food supplements. Intriguingly, a substantial synergistic inhibitory effects on cell growth, DNA synthetic activity and percentage of cells in S phase were noticed when YATROS was combined with 5-Fluorouracil, reducing both dose and timing of exposure of C26 cells to the drug. Moreover, by inducing cytoskeleton reorganization and E-cadherin expression, YATROS can interfere with tumor cell invasiveness. These indications of an agonistic interaction between YATROS and 5-Fluorouracil in colon carcinoma cells may be of interest for clinical applications, and thus merit further investigation.

Purpose: This pilot study was conducted to evaluate the cleaning efficacy of an angled implant brush for home oral hygiene of full-arch fixed-implant prostheses. Methods: Forty-one patients treated with a full-arch implant rehabilitation in the maxilla or mandible (164 implants) for at least 4 months were enrolled. The screw-retained fixed prostheses were removed and baseline (T0) parameters were recorded, including plaque index (PI), probing depth (PD), and bleeding on probing (BOP). All patients completed a 5-item questionnaire on hygiene maintenance and received an implant brush for home hygiene. After 1 month (T1) PI, PD, and BOP were recorded again and patients completed a 7-item questionnaire to evaluate their satisfaction with the implant brush. One-way repeated-measures analysis of variance was conducted to evaluate the significance of changes in PI, PD, and BOP. A P value <0.05 was considered to indicate statistical significance. Results: A statistically significant reduction of BOP (0.62±0.6 at T0 vs. 0.5±0.5 at T1; P=0.032) was found, while no statistically significant changes in PD (1.74±0.5 mm at T0 vs. 1.77±0.5 mm at T1; P=0.050) or PI (1.9±0.7 at T0 vs. 1.7±0.7 at T1; P=0.280) occurred. According to the 7-item questionnaire, patients reported no difficulty in using the angled brush (63.4%) and deemed it highly (46.3%) or very highly (4.8%) effective in improving their home oral hygiene. Conclusions: Within the limits of the present pilot study, the patients experienced a reduction of BOP 1 month after being instructed to use the angled implant brush. The angled implant brush appeared to be a well-accepted device for home-care hygiene of full-arch fixed-implant rehabilitations.
