There were gaps between guidelines and practice when surgery was the only treatment for aortic stenosis (AS). This study analyzed the decision to intervene in patients with severe AS in the EORP VHD (EURObservational Research Programme Valvular Heart Disease) II survey. Among 2,152 patients with severe AS, 1,271 patients with high-gradient AS who were symptomatic fulfilled a Class I recommendation for intervention according to the 2012 European Society of Cardiology guidelines; the primary end point ...

There are four beta-glycosidases (betagly1, betagly2, betagly3, and betagly4) in Tenebrio molitor midgut larvae. betagly1 and betagly2 have identical kinetic properties, and differ in a few amino acid residues. Purified betagly1 was used to raise antibodies in a rabbit. The resulting antiserum recognizes in a Western blot only betagly1 and betagly2 in midgut tissue homogenates and contents. An immunocytochemical study carried out using confocal fluorescence and immunogold techniques showed that betagly1+ ...

No Brasil, em 1999, foi aprovada a Resolução nº 258/99 do CONAMA (Conselho Nacional do Meio Ambiente) que instituiu a responsabilidade do produtor e do importador pelo ciclo total do produto, ou seja, a coleta, o transporte e a disposição final.

Constrictive pericarditis is a uncommom disease in children. We have now encountered pericardial thickening as the cause of severe constrictive physiology in two patients, one also having haemodynamic features of restrictive cardiomyopathy. Both patients, who had refractory ascites and evidence of increased systemic venous pressure, underwent Doppler echocardiography, cardiac catheterisation, and magnetic resonance imaging. Resonance imaging failed to show any thickning of the pericardium, but cardiac ...

Using a Western blot technique that allows quantitative detection of antibody reactivities to a large number of antigens, serum IgG and IgM antibody repertoires were compared in a group of 19 patients with a diagnosis of idiopathic thrombocytopenic purpura (ITP) and respective healthy controls. The results show that, irrespective of the duration of thrombocytopenia, age of the patients, and type of therapy, all ITP donors share characteristic alterations of serum antibody reactivity patterns on homologous ...

The use of the dorsalis pedis flap with vascularized extensor tendons was presented. An anatomic study has been carried out that has shown that the vascularization of the foot extensor tendons can be exclusively dependent on the blood contribution coming from the dorsalis pedis artery. In two cases that are presented and followed up for over a year after the surgery, the functional results obtained are good in the hand and aesthetically acceptable in the foot.

Abstract Twenty‐six patients with head and neck tumors were submitted to 27 microvascular reconstructive procedures. In 15, the mandible was reconstructed using the rib (4), iliac crest (7), and scapula (4). Nine patients underwent craniofacial reconstructions with the latissimus dorsi (5), rectus abdominis (2), greater omentum (2), and scapular (1) flaps. Two patients received a jejunum (1) and a stomach plus greater omentum (1) flaps for pharyngoesophageal reconstruction. Three illustrative cases, one ...

Tiron is an anionic surface active agent, known to render extremely efficient results in the dispersion of metallic oxides such as Al(2)O(3), ZrO(2) and TiO(2). Its dispersion mechanism upon these oxides outcomes from efficient complexation of the corresponding metallic cation, leading to chemisorption of the dispersant molecule upon the oxide surface. In the present work, the effect of Tiron on the stabilization of CuO particles in aqueous suspension is studied to clarify the dispersant's role ...

The water gas shift reaction (WGSR) is an important step in the commercial prodution of high pure hydrogen for several applications. In order to find alternative catalysts to this reaction, the effect of cobalt on the activity of iron-based catalysts was studied in this work. It was found that cobalt changed the properties of iron oxide depending on its content. In small amounts (Co/Fe(molar)= 0.05), it did not affect significantly the specific surface area but decreased the catalytic activity, a ...
