Biomarkers of Orthodontic Patients After Use of 1% Brazilian Red Propolis Toothpaste: A Randomized Clinical Study.

Aim: To evaluate the salivary biomarkers and plaque index after a treatment with a propolis-contained toothpaste. Materials and Methods: This is a longitudinal, randomized, double-blind study where 76 participants were randomized into two groups: Group I: Fluoridated Red Propolis toothpaste; Group II: Fluoridated toothpaste. The participants were selected in a municipality without fluoridated public water. All participants received standardized oral hygiene instructions from the same instructor for 3 daily brushings (after breakfast, after lunch, and before bed) for a period of 2 min; Saliva samples were collected before (D0) and after 28 days (D28) of treatment for analysis of pH and total protein, amylase, and IL-10. Saliva was collected in the initial consultation and on return, totaling two collections. All samples were collected under the same conditions, by the same operator and between 9:00 AM and 11:00 AM in order to minimize the influence of circadian rhythm on salivary flow. Results: On D0 and D28, the various treatments had no effect on total salivary proteins (G1: P = 0.0746; G2: P = 0.2144), and the pH stayed about the same. Additionally, there was no change in the amylase activity in G1 (P = 0.1877) or G2 (P = 0.4674). Significant decreases in G1 (P < 0.0001) and G2 (P = 0.03) were observed with IL-10. There was no statistically significant difference in the salivary flow between the BRP toothpaste-treated group (P = 0.172) and the commercial fluoridated toothpaste-treated group (P = 0.329). Compared to G2 (P = 0.03), G1 showed a superior decline in the plaque index (P = <0.0001). Conclusions: After 28 days of using the toothpastes, there were no changes in the amylase, pH, or total protein indicators. After 28 days, there was a decrease in the propolis group's IL-10 dose and plaque index.

Anti-inflammatory activities of arthropod peptides: a systematic review.

Peptides obtained from different animal species have gained importance recently due to research that aims to develop biopharmaceuticals with therapeutic potential. In this sense, arthropod venoms have drawn attention, not only because of their toxicity but mainly for the search for molecules with various bioactivities, including anti-inflammatory activity. The purpose of the present study is to gather data available in the literature on new peptides derived from arthropod species with anti-inflammatory potential. This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Studies on peptides from arthropods that display anti-inflammatory activity were retrieved from PubMed, Scopus, Web of Science, and Google Scholar databases. The bibliographic research started in 2020 and searched papers without a limit on the publication date. The articles were analyzed using a search string containing the following terms: "Peptides" and "Anti-inflammatory", in combinations such as "Ant", "Bee", "Wasp", "Crab", "Shrimp", "Scorpion", "Spider", "Tick" and "Centipedes". Besides, a search was carried out in the databases with the terms: "Peptides", "Antitumor", or "Anticancer", and "Arthropods". Articles that met the inclusion and exclusion criteria totalized 171, and these served for data extraction. Additionally, the present review included anti-inflammatory peptides with anticancer properties. Peptides with confirmed anti-inflammatory activity were from insects (ants, bees, and wasps), crustaceans (shrimp and crabs), arachnids (scorpions, spiders, and ticks), and centipedes. These arthropod peptides act mainly by decreasing pro-inflammatory cytokines as analyzed in vitro and in vivo. Some showed significant antineoplastic activity, working in essential cellular pathways against malignant neoplasms.

Antibiofilm Activity on Candida albicans and Mechanism of Action on Biomembrane Models of the Antimicrobial Peptide Ctn[15-34].

Ctn[15-34], the C-terminal fragment of crotalicidin, an antimicrobial peptide from the South American rattlesnake Crotalus durissus terrificus venom, displays remarkable anti-infective and anti-proliferative activities. Herein, its activity on Candida albicans biofilms and its interaction with the cytoplasmic membrane of the fungal cell and with a biomembrane model in vitro was investigated. A standard C. albicans strain and a fluconazole-resistant clinical isolate were exposed to the peptide at its minimum inhibitory concentration (MIC) (10 µM) and up to 100 × MIC to inhibit biofilm formation and its eradication. A viability test using XTT and fluorescent dyes, confocal laser scanning microscopy, and atomic force microscopy (AFM) were used to observe the antibiofilm effect. To evaluate the importance of membrane composition on Ctn[15-34] activity, C. albicans protoplasts were also tested. Fluorescence assays using di-8-ANEPPS, dynamic light scattering, and zeta potential measurements using liposomes, protoplasts, and C. albicans cells indicated a direct mechanism of action that was dependent on membrane interaction and disruption. Overall, Ctn[15-34] showed to be an effective antifungal peptide, displaying antibiofilm activity and, importantly, interacting with and disrupting fungal plasma membrane.

Avaliação do desenvolvimento in vitro de embriões bovinos após exposição à crotamina linear / Evaluation of bovine embryo in vitro development after exposure to linear crotamine

The present study investigated the effects of different concentrations of linear crotamine (CrL), used asagent for cell transfection, on in vitro development of bovine embryos. Embryos were exposed to 0; 5 and 12.5µM of CrL in Synthetic Oviductal Fluid (SOF) for 6 h. Vehicle solution was NaCl 150 mM and not exposedembryos (in vitro fertilized-IVF group) was included. In vitro developmental competence was evaluated bycleavage (day 2), blastocyst (day 7 and 8), and hatching (day 8) rates. No difference (P > 0.05) was observedamong CrL groups and control group (IVF) for all observed parameters. In conclusion, the use of the tested CrLconcentrations for 6 h during in vitro culture of bovine embryos have no deleterious effects on embryodevelopment.
