1. Influência da intensidade de carregamento e utilização de placa oclusal plana em supraestruturas metálicas parafusadas sobre implantes: estudo fotoelástico / Influence of the intensity of loading and use of an occlusal splint flat screw-retained metal superstructures on implants: photoelastic study
Objetivo: Avaliar por meio do estudo fotoelástico qualitativo as tensões geradas no longo eixo dos implantes e interimplantes nas regiões cervical, média e apical quando submetidos a diferentes carregamentos com ou sem interposição de placa oclusal plana. Método: Foram confeccionados quatro modelos fotoelásticos, com dois implantes hexágono externo

2. Validação de uma bicicleta ergométrica de ciclismo indoor
The adaptation of load system an bicycle ergometer for indoor cycling (BEIC) allowed its classification as an cycle ergometer, however, its validation must be tested. Because of this it was decided to test the validation of BEIC and the contested Monark. Forty and two cyclists of a regional level (Mean-DP): age 33,7 (8,4) years; stature 175,3 (6,3) cm; body

3. Análise das estratégias de movimento adotadas durante a realização de manuseio de carga.
Despite recent technological advances, occupational activities of manual nature are still essential in many sectors and industries. Such activities impose risky conditions, which are inherent to its nature and can be responsible for musculoskeletal injuries. In addiction, the complexity and the interaction of risk factors, many still not comprehended, that a

4. Focal adhesion kinase is a load-dependent governor of the slow contractile and oxidative muscle phenotype
Striated muscle exhibits a pronounced structural–functional plasticity in response to chronic alterations in loading. We assessed the implication of focal adhesion kinase (FAK) signalling in mechano-regulated differentiation of slow-oxidative muscle. Load-dependent consequences of FAK signal modulation were identified using a multi-level approach after ele

5. Effects of exerimental right ventricular hypertrophy on myocardial blood flow in conscious dogs.
The effects of right ventricular hypertrophy on the overall and regional distribution of myocardial blood flow in the absence of an elevated coronary arterial driving pressure were evaluated in 18 concscious dogs subjected to a chronic pressure overload of the right ventricle induced by pulmonary artery constriction. The sustained pressure overload for durat

6. Myosin heavy chain messenger RNA and protein isoform transitions during cardiac hypertrophy. Interaction between hemodynamic and thyroid hormone-induced signals.
Expression of the cardiac myosin isozymes is regulated during development, by hormonal stimuli and hemodynamic load. In this study, the levels of expression of the two isoforms (alpha and beta) of myosin heavy chain (MHC) during cardiac hypertrophy were investigated at the messenger RNA (mRNA) and protein levels. In normal control and sham-operated rats, the

7. The α1A/C- and α1B-adrenergic receptors are required for physiological cardiac hypertrophy in the double-knockout mouse
Catecholamines and α1-adrenergic receptors (α1-ARs) cause cardiac hypertrophy in cultured myocytes and transgenic mice, but heart size is normal in single KOs of the main α1-AR subtypes, α1A/C and α1B. Here we tested whether α1-ARs are required for developmental cardiac hypertrophy by generating α1A/C and α1B double KO (ABKO) mice, which had no cardi

8. Increased p53 mutation load in nontumorous human liver of Wilson disease and hemochromatosis: Oxyradical overload diseases
Hemochromatosis and Wilson disease (WD), characterized by the excess hepatic deposition of iron and copper, respectively, produce oxidative stress and increase the risk of liver cancer. Because the frequency of p53 mutated alleles in nontumorous human tissue may be a biomarker of oxyradical damage and identify individuals at increased cancer risk, we ha

9. Pressure-independent enhancement of cardiac hypertrophy in natriuretic peptide receptor A–deficient mice
Mice lacking natriuretic peptide receptor A (NPRA) have marked cardiac hypertrophy and chamber dilatation disproportionate to their increased blood pressure (BP), suggesting, in support of previous in vitro data, that the NPRA system moderates the cardiac response to hypertrophic stimuli. Here, we have followed the changes in cardiac function in response to
