[Spatial and temporal patterns of mortality among motorcyclists in a State of the Brazilian Northeast in the 21st century].

The scope of this work was to analyze the trend and distribution of mortality among motorcyclists in traffic accidents in the State of Alagoas. It involved an ecological study relating to all deaths resulting from motorcycle accidents in the state in the period from 2001 to 2015. Mortality data were obtained from the Mortality Information System (MIS).

Dengue associated with severe cutaneous leukocytoclastic vasculitis and pericardial effusion: a case report.

Dengue is a viral disease, caused by an arbovirus of the genus Flavivirus. In Brazil, its incidence rate is high with a broad clinical spectrum. This report discusses a rare case of dengue associated with cutaneous leukocytoclastic vasculitis and pericardial effusion with eminence of cardiac tamponade in a previously healthy patient with no comorbidities.

Adhesive performance of silver-palladium-copper-gold alloy and component metals bonded with organic sulfur-based priming agents and a tri-n-butylborane initiated luting material.

Objective: The purpose of the current study was to evaluate the effect of thione-based metal priming agents on the adhesive behavior of a Ag-Pd-Cu-Au alloy and component metals bonded with an acrylic resin.

Materials And Methods: Disk specimens (10 mm in diameter by 3 mm thick) were prepared from a silver-palladium-copper-gold (Ag-Pd-Cu-Au) alloy (Castwell M.C.

Adhesive bonding of Ti-6Al-7Nb alloy and component metals with acidic primers and a tri-n-butylborane initiated resin.

Purpose: To evaluate the effects of acidic functional monomers on the bond strength and durability of an acrylic resin joined to Ti-6Al-7Nb alloy and component metals.

Materials And Methods: Disk specimens of two different sizes (10 and 8 mm in diameter and 2.5 mm in thickness) were prepared from uncast Ti-6Al-7Nb alloy, titanium, aluminum, and niobium.

Evaluation of thiouracil-based adhesive systems for bonding cast silver-palladium-copper-gold alloy.

This study aimed to evaluate the effect of adhesive systems based on a thiouracil monomer on bonding to silver-palladium-copper-gold (Ag-Pd-Cu-Au) alloy (Castwell M.C.12).

Effect of alumina air-abrasion on mechanical bonding between an acrylic resin and casting alloys.

This study examined the effect of alumina air-abrasion with different pressure on bonding between an acrylic resin and casting alloys. Disk specimens (8 and 10 mm in diameter) were cast from a silver-palladium-copper-gold (Ag-Pd-Cu-Au, Castwell M.C.

Epinephrine quantification in pharmaceutical formulations utilizing plant tissue biosensors.

A plant tissue biosensor associated with flow injection analysis is proposed to determine epinephrine in pharmaceutical samples. The polyphenol oxidase enzymes present in the fibers of a palm tree fruits (Livistona chinensis), catalyses the oxidation of epinephrine to epinephrinequinone as a primary product. This product is then electrochemically reduced (at -0.

Electrochemical behavior of pyrroloquinoline quinone immobilized on silica gel modified with zirconium oxide.

Pyrroloquinoline quinone (PQQ) was immobilized on the silica gel surface modified with zirconium oxide, designated as Si:Zr, by the carboxylic groups of the PQQ molecule and the zirconium oxide on the silica surface. The electrochemistry of PQQ immobilized on the Si:Zr matrix, incorporated in a carbon paste electrode, was evaluated using the cyclic voltammetry technique. The Si:Zr:PQQ-modified electrode showed a redox couple at E(m)=(E(pa1)+E(pc))/2=-0.

Lysophosphatidic acid enhances in vivo infiltration and activation of guinea pig eosinophils and neutrophils via a Rho/Rho-associated protein kinase-mediated pathway.

Lysophosphatidic acid (LPA) has been shown to be a chemoattractant in in vitro studies. The present study was carried out to determine whether LPA enhances infiltration of inflammatory cells in in vivo studies with guinea pigs. LPA (1 - 10 microg/ml), when by guinea pigs for 5 min, substantially increased the numbers of eosinophils and neutrophils in the bronchoalveolar lavege fluid (BALF), which was recovered at over 4 h after the inhalation of LPA.

Synthesis and antirheumatic activity of the metabolites of esonarimod.

We have developed esonarimod, (+/-)-2-acetylthiomethyl-4-(4-methylphenyl)-4-oxobutanoic acid, as a new antirheumatic drug. Now we describe herein the preparation of the enantiomers of (+/-)-deacetylesonarimod, the pharmaceutically active metabolites of esonarimod, and comparison of their antirheumatic activities. No significant difference has been observed between the two enantiomers.

Role of Rho-associated protein kinase and histamine in lysophosphatidic acid-induced airway hyperresponsiveness in guinea pigs.

Inhalation of oleoyl lysophosphatidic acid (LPA) induced airway hyperresponsiveness to acetylcholine (ACh). In contrast, palmitoyl and stearoyl LPA exerted minimal effects. Airway hyperresponsiveness was inhibited by inhalation of Y-27632, an inhibitor of Rho-associated protein kinase (ROCK).
