13. Radioiodine plus recombinant human thyrotropin do not cause acute airway compression and are effective in reducing multinodular goiter
Recombinant human thyrotropin (rhTSH) reduces the activity of radioiodine required to treat multinodular goiter (MNG), but acute airway compression can be a life-threatening complication. In this prospective, randomized, double-blind, placebo-controlled study, we assessed the efficacy and safety (including airway compression) of different doses of rhTSH asso

14. Investigation of structural, electronic and magnetica properties of Ca2-xLaxFelrO6, Sr2-xLaxFelrO6 e TbMnO3 oxides / Investigação as propriedades estruturais, eletronicas e magneticas dos oxidos Ca2-xLaxFelrO6, Sr2-xLaxFelrO6 e TbMnO3
For many decades the transition metal oxides are subject of great scientific interest because of the wide variety of interesting physical properties and their potential technological applications. More recently, for example, oxides of transition metals with multiferroic properties have been considered as potential magneto-electronic devices. Many transition

15. Efficacy and safety of creatine supplementation combined with exercise training in type II diabetic patients: a randomized, double-blind, placebo-controlled, clinical trial / Eficácia e segurança da suplementação de creatina acompanhada de treinamento físico em diabéticos tipo 2: estudo clínico, randomizado, duplo-cego, controlado por placebo
Some studies have suggested that creatine supplementation may attenuate insulin resistance, but whether this supplement is safe remains uncertain. In light of this, the aim of this trial was to investigate the efficacy and safety of creatine supplementation combined with exercise training in patients with type II diabetes. A randomized, double-blind, placebo

16. Isoxazolinas: uma classe de materiais avançados revisitada
The synthesis and characterization of novel series of liquid crystalline materials containing N-heterocyclic isoxazoline are described. These molecules were obtained from the reaction of 1,3-dipolar cycloaddition of nitrile oxides to different compounds containing double bonds. Thermal properties were analyzed by MOLP, DSC and TGA, and optical properties by

17. Immobilization of laccase on hybrid layered double hydroxide
Crystals of Mg/Al layered double hydroxide were synthesized by alkaline precipitation and treated in an aqueous solution of glutamic acid. The glutamate ions were not intercalated into the interlayer space, but were detected in the material by Fourier transform infrared spectroscopy, suggesting that only the external surfaces of crystals were modified with g

18. Electron magnetic resonance in studies of biologically-relevant systems. / Ressonância magnética eletrônica no estudo de sistemas de interesse biológico
In this work, we made use of the Electron Paramagnetic Resonance (EPR) spectroscopy along with the so-called reporter group technique and extensive spectral simulations by means of the software NLSL to investigate the interaction of nicotine with model membranes. Besides that we also employed Ferromagnetic Resonance (FMR), which is a technique similar in man

19. Efeitos biológicos de nanopartículas magnéticas recobertas por bicamada de ácido láurico : estudos in vitro e in vivo
Nanomaterials, due to its unique physical properties, are promising agents for biomedical use. Magnetic nanoparticles (MNP) covered with double layer of lauric acid (LA-MNP) were tested had their cytotoxicity evaluated in vitro mesangial cells (CHMI), fibroblasts (FHN) and peritoneal macrophages, showing decrease in cell viability only in macrophages, when t

21. Aspectos clinicos da deglutição, da fonoarticulação e suas correlações geneticas na Doença de Machado Joseph / Clinical aspects of swallowing, voice/speech and genetic correlation in Machado Joseph disease
Introduction: Machado-Joseph (MJO) is a degenerative, autosomal dominant inherited disease, common to populations of Portuguese descent. It is a form of triplet repeat genetic disorder. The original mutation is caused by an abnormal repetition of the CAG code on chromosome 14q. The estimated prevalence in Brazil is 1: 1 00,000. The polymorphic symptoms appea

Comparação com a ecocardiografia bidimensional e a ressonância magnética cardiovascular / Value of real-time three-dimensional echocardiography in patients with hypertrophic cardiomyopathy. Comparison with twodimensional echocardiography and magnetic resonance imaging
INTRODUCTION: Real-time three-dimensional echocardiography (RT3D) has been demonstrated an accurate technique for the quantification of left ventricular (LV) volumes, ejection fraction (LVEF), and mass. In patients with hypertrophic cardiomyopathy (HCM), in which alterations of ventricular morphology are common, cardiac structural analysis is of utmost impor

24. "Propriedades estruturais de agregados anfifílicos catiônicos: interação com material genético" / structural properties of cationic amphiphilic aggregates: interaction with genetic material
Though less efficient than viral vectors, cationic lipids have been used as carriers in gene therapy. They offer several advantages over viral vectors, including the low immunogenic and inflammatory responses, the potential transfer of unlimited-size expression units, and the possibility for engineered cell-specific targeting. However, the interaction betwee
