1. Prostaglandin E2 Induces Expression of Mineralization Genes by Undifferentiated Dental Pulp Cells
Resumo A Prostaglandina E2 (PGE2) é um mediador lipídico comumente liberado durante a inflamação. Este estudo teve como objetivo investigar o potencial da PGE2, solúvel ou na forma de microesferas, na diferenciação de células-tronco de polpa dentária. Microesferas de PGE2 (MS) foram preparadas por meio do processo de extração/evaporação de solve

2. Microesferas lipídicas encapsuladas com proteínas antigênicas da membrana de Leishmania amazonensis com potencial aplicação terapêutica / Lipid microspheres loaded with antigenic membrane proteins of the Leishmania amazonensis as a potential therapeutical Application.
Microesferas lipídicas (ML) são excelentes sistemas de delivery de drogas e são relativamente estáveis. O Objetivo deste trabalho foi desenvolver um sistema capaz de encapsular proteínas antigênicas da membrana de L. amazonensis. Proteínas de membrana são importantes na formulação de vacinas, uma vez que estas proteínas são os primeiros component

3. Studies about the effects of the in vivo administration of Leukotriene B4 or Prostaglandin E2-loaded biodegradable microspheres on model of murine histoplasmosis / Estudos sobre os efeitos da administração in vivo de microesferas biodegradáveis contendo Leucotrieno B4 ou Prostaglandina E2 em modelo de histoplasmose murina
Leukotrienes and prostaglandins are arachidonic acid metabolites, which participate in the inflammatory response and modulate cytokines release in both adaptive and innate immune responses. However, some physicochemical characteristics of these mediators, such as poor solubility in water and chemical instability, make them difficult to administer in vivo. In

4. Uterine prostaglandin E secretion and uterine blood flow in the pregnant rabbit.
Studies were performed in pregnant rabbits to assess the effect of inhibition of prostaglandin synthesis on uterine blood flow. Cardiac output and uteroplacental blood flow (UPBF) were measured using radiolabeled microspheres. Prostaglandin E (PGE) concentration was measured by radioimmunoassay in the uterine vein and peripheral artery of the pregnant nephre

5. Particle uptake and translocation across epithelial membranes.
Oral delivery of drugs and vaccines has many advantages over other routes of administration. For example, for vaccination, enteric delivery may result in the induction of a mucosal immune response against pathogens which colonise and invade the mucosa. However, the oral delivery of peptide or protein drugs or antigens is beset with problems, such as gastroin

6. Electron microscopic observation of domain movement in reconstituted erythrocyte membranes.
The movement of labeled concanavalin A (Con A) receptors in reconstituted human erythrocyte membranes was observed directly in an electron microscope, using an environmental stage that kept the sample fully hydrated at all experimental temperatures. Human erythrocyte membrane ghosts were spread on the air/water interface in a Langmuir trough. The surface mon
