Advances in soft nanoparticle-based platforms for human and veterinary trichomoniasis therapy: A scoping review.

This scoping review focuses on drug delivery systems based on soft materials designed for the administration of drugs with anti-Trichomonas vaginalis activity. It primarily examines their use in addressing human trichomoniasis, exploring their physicochemical characteristics, in vitro and in vivo evaluation and identifying existing challenges and gaps. Given the economic burden and the One Health approach, formulations developed aiming at treating animal infections - cattle and poultry - were also discussed.

Evaluation of the glymphatic system in relapsing remitting multiple sclerosis by measuring the diffusion along the perivascular space.

Background: In the inflammatory process of multiple sclerosis (MS) several toxic waste products are generated. The clearance of these products might depend on the glymphatic system; however, it's preserved function in MS is uncertain. Recently, it was suggested that this 'waste clearance' system can be examined by measuring the diffusion along the perivascular space (ALPS) index.

Effect of an experimental desensitizer with a hydroxyapatite-capsaicin composite applied before in-office dental bleaching on hydrogen peroxide diffusion, color and surface changes.

Objective: To evaluate a prior application of an experimental desensitizer containing a hydroxyapatite-capsaicin composite (HAp-CAP) in different concentrations on hydrogen peroxide (HP) diffusion into the pulp chamber, bleaching efficacy (BE) and on physical and chemical alterations of the enamel surface after in-office bleaching.

Materials And Methods: Forty sound premolars were randomized in five groups according to each experimental condition (n = 8): no bleaching (negative control), only bleaching (positive control), 0.1%, 1% and 5% of HAp-CAP.

Insecticidal and Repellent Activity of Essential Oil and Its Pure Compounds Against Imported Fire Ants (Hymenoptera: Formicidae).

Kunth (Piperaceae) essential oil (EO) was evaluated for its toxicity and repellency against red imported fire ants (RIFA), Buren, and a hybrid (HIFA) of red ( and black ( Forel) imported fire ants. Through bioactivity-guided fractionation, two major components, elemicin and myristicin, were isolated from the EO. Removal of treated sand in a digging bioassay was used as the criterion for repellency.

Evaluation of hydrogen peroxide diffusion in the pulp chamber, bleaching efficacy, and physicochemical properties of an experimental in-office bleaching gel containing a hydroxyapatite-capsaicin composite.

This study assessed the hydrogen peroxide (HP) diffusion into the pulp chamber, bleaching efficacy (BE), surface roughness (Ra), and Knoop microhardness (KHN) of an experimental bleaching gel containing a hydroxyapatite-capsaicin composite (HAp-CAP). Human premolars were randomly assigned to three groups (n = 9) based on the dental bleaching gel used (50 min; one session): only 35% HP, 35% HP + HAp-CAP, and not exposed to bleaching (negative control; NC). HP diffusion (µg/mL) into the pulp chamber was assessed using UV-Vis spectrophotometry, and BE (ΔE, ΔE, and WI) was evaluated using a digital spectrophotometer.
