Hamamelis virginiana L. extract presents antimicrobial and antibiofilm effects, absence of cytotoxicity, anti-inflammatory action, and potential to fight infections through the nitric oxide production by macrophages.

The potential of H. virginiana L. was evaluated against Candida spp.

Antibiofilm action of glycolic extract over and absence of toxicity in .

Objectives: This study aimed to evaluate the antibiofilm activity and toxicity of the glycolic extract of "" over multidrug-resistant strains of as alternative therapy to be investigated.

Methods: A bacterial inoculum of each bacterial strain (4a, 5a, 9a, 12a, ATCC 19606) of was prepared and adjusted by the spectrophotometer. The microdilution broth method was performed to determine the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC).

An analysis of the quality indicators of the organ donation process in São Paulo, Brazil.

Background: Few studies have investigated whether quality initiatives in the process of organ donation yield better results of the organ donation process.

Objective: To analyze whether the indicators of the organ donation process in Brazilian hospitals meet the standards established by the Organ Donation European Quality System (ODEQUS).

Design: We evaluated the quality of the organ donation in a selected group of Brazilian hospitals served by the Nucleus of Organ Procurement (NOP) using standards of the ODEQUS.

[Protective effect of sodium bicarbonate on radiological contrast medium-induced nephropathy in rats].

Radiological iodinated contrasts (IC) agents cause acute kidney injury (AKI). To evaluate the renoprotective effect of sodium bicarbonate (Bic) on renal function (creatinine clearance [Clcr], Jaffé, and Clcr mLmin -1 x100 g-1) and the oxidative profile (peroxide excretion, urinary peroxides, urinary malondialdehyde, FOX-2 expression, and thiobarbituric acid reactive substance [TBARS; nmol/mg Cr]) in rats treated with an IC agent. Adult male Wistar rats weighing 250-300 g were treated once daily for 5 days with one of the following treatments: saline (0.

Fluoxetine inhibits inflammatory response and bone loss in a rat model of ligature-induced periodontitis.

Background: Fluoxetine, a selective serotonin reuptake inhibitor, has been found recently to possess anti-inflammatory properties. The present study investigates the effects of fluoxetine on inflammatory tissue destruction in a rat model of ligature-induced periodontal disease.

Methods: Thirty male Wistar rats were randomly assigned into three groups (n = 10 animals per group): 1) control rats (without ligature); 2) rats with ligature + placebo (saline; oral gavage); and 3) rats with ligature + fluoxetine (20 mg/kg/day in saline; oral gavage).

Prevalence and distribution of serotype-specific genotypes of Aggregatibacter actinomycetemcomitans in chronic periodontitis Brazilian subjects.

Objective: Previous studies have suggested that Aggregatibacter actinomycetemcomitans is involved in the aetiology of aggressive periodontitis as well as chronic periodontitis. In addition, some authors have also reported that serotype-specific antigens of A. actinomycetemcomitans determine the severity of disease.

Diametral tensile strength of dual-curing resin cements submitted exclusively to autopolymerization.

Objectives: To evaluate, at different times, the diametral tensile strength (DTS) of dual-curing resin cements that were not photopolymerized.

Method And Materials: Equal amounts of base and catalyst pastes of Panavia F (Kuraray), Variolink II (Vivadent), Rely X (3M ESPE), and Enforce (Dentsply) were mixed and inserted into cylindrical molds (4 x 2 mm) (n = 10). Cements were not photopolymerized.

Shear bond strength of metal-ceramic repair systems.

Statement Of Problem: When clinical fractures of the ceramic veneer on metal-ceramic prostheses can be repaired, the need for remake may be eliminated or postponed. Many different ceramic repair materials are available, and bond strength data are necessary for predicting the success of a given repair system.

Purpose: This study evaluated the shear bond strength of different repair systems for metal-ceramic restorations applied on metal and porcelain.
