Objective:  The focus of this triple-blind randomized study was to evaluate the biocompatibility of a new root canal filling sealer (RCFS) based on tristrontium aluminate and dodecacalcium hepta-aluminate in living tissue.

Material And Methods:  Forty-five Wistar rats () were divided into three groups: control (polyethylene), sealer (Bio-C Sealer, Londrina, PR, Brazil), and experimental (tristrontium aluminate and dodecacalcium hepta-aluminate). The tissues were analyzed under an optical microscope to assess different cellular events at different time intervals (7, 15, and 30 days).

Objective: The objective of this study was to evaluate the hemostatic activity of the sap from (Pohl) Baill. in rats.

Materials And Methods: Twenty-four Wistar rats were randomized into four groups ( = 6): the JM25 and JM40 groups were treated with ethanolic extract from the sap of , in a concentration of 25 and 40 mg·mL, respectively; the MO group was treated with Monsel's solution and the control group SC with a 0.

Article Synopsis
  • The study aimed to create a chitosan-based biomaterial with calcium hydroxide and chlorhexidine to reduce microorganisms in root canals.
  • Chitosan was prepared by dissolving it in acetic acid, and different samples were created using varying concentrations of the materials, which were then characterized using techniques like FTIR and XRD.
  • The results showed that the new formulation demonstrated strong antimicrobial activity, particularly in samples containing chlorhexidine, suggesting its potential use as an effective intracanal treatment.

Background: Polymorphisms of enzymes involved in histamine biodisposition may affect clinical symptoms in diseases related to histamine, such as asthma or allergic rhinitis (AR).

Objective: This study aims to analyse two common polymorphisms in genes coding for histamine-metabolizing enzymes in patients with allergic diseases.

Methods: Five-hundred and sixty-five individuals participated in the study, including 270 unrelated patients with asthma and/or AR recruited from a single centre and 295 healthy volunteers.
