ABSTRACT Antimicrobial photodynamic therapy (aPDT) involves the association of a photosensitizing agent with a light source with the goal of causing apoptosis or microbial lysing. The use of compounds with natural active principles is gaining prominence throughout the world. Several studies from groups t...
Urease from Canavalia ensiformis seeds was the first enzyme ever to be crystallized, in 1926. These proteins, found in plants, bacteria and fungi, present different biological properties including catalytic hydrolysis of urea, and also enzyme-independent activities, such as induction of exocytosis, pro-i...

The objective of this study was to determine the effects of coating nanoparticles of titanium dioxide (TiO2 NPs) and irradiation -UV on plates of titanium (Ti) for the adhesion and proliferation of human gingival fibroblasts (HGF). A total of 15 Ti plates were divided into three groups (n = 5); (i) contr...
ABSTRACT Topically applied therapy is the most common way to treat ocular diseases, however given the anatomical and physiological constraints of the eye, frequent dosing is required with possible repercussions in terms of patient compliance. Beyond refractive error correction, contact lenses (CLs) have,...

ABSTRACT The use of nanocarriers as drug delivery systems for therapeutic or imaging agents can improve the pharmacological properties of commonly used compounds in cancer diagnosis and treatment. Advances in the surface engineering of nanoparticles to accommodate targeting ligands turned nanocarriers at...
Arranjos supramoleculares combinando o lípide catiônico brometo de dioctadecildimetilamônio (DOD) com polímeros, como carboximetilcelulose (CMC) e cloreto de poli(dialildimetilamônio) (PDDA), foram preparados na forma de nanopartículas (NPs), na ausência ou presença de antimicrobiano tradicional,...
O objetivo deste trabalho foi avaliar in vitro a ação do trimetafosfato de sódio microparticulado (TMPm) ou nanoparticulado (TMPn) associado ao fluoreto (F) em formulações de dentifrícios na obliteração dos túbulos dentinários (TD), concentração mineral e condutância hidráulica. Blocos de d...
