1. Effects of Hyperthyroidism on Contractility and Na+/Ca2+ Exchanger Activity in the Isolated Papillary Muscle of Rats
Abstract Background: Hyperthyroidism (Hy) is an endocrine disorder, in which the thyroid hormones markedly alter the cardiac function. Increased myocardial contractility and cardiac output, improvement in diastolic relaxation, changes in electrical activity, increments in ventricular mass, and arrhythmias have been reported. However, the influences of thyro

2. Influence of Masticatory Behavior on Muscle Compensations During the Oral Phase of Swallowing of Smokers
Abstract Introduction Chewing and swallowing are physiologically interconnected functions, which share motor structures and supranuclear regions of the central nervous system (CNS), involving a sensorimotor synchrony. Objective To analyze the influence of masticatory behavior on muscular compensations in the oral phase of swallowing in smokers compared w

3. Quadriceps muscle weakness influences the gait pattern in women with knee osteoarthritis
Abstract Background: Osteoarthritis is the most prevalent rheumatic disease in the population and is characterized by limitation of main functional activities of daily living, as the gait. Muscle strength is a variable that may be related to performance in daily tasks. Therefore, we to analyze the gait pattern in individuals with knee osteoarthritis (KOA) a

4. Do muscular strength and jump power tests reflect the effectiveness of training programs for basketball athletes?
Abstract Aims: Muscular strength (MS) and jump power (JP) tests are used to assess athletic ability and measure the effectiveness of training programs. However, their use in various sport modalities needs to be investigated further. This study aimed to explore the changes in MS and JP during three different moments of a macrocycle training session and veri

5. Real-time premature ventricular contractions detection based on Redundant Discrete Wavelet Transform
Abstract Introduction Premature Ventricular Contraction (PVC) is among the most common types of ventricular cardiac arrhythmia. However, it only poses danger if the person suffers from a heart disease, such as heart failure. Hence, this is an important factor to consider in heart disease people. This paper presents an ECG real-time analysis system for PVC

6. Effects of taurine supplementation in elite swimmers performance
Abstract AIM Taurine is considered a semi-essential amino acid characterized by having various physiological functions in the body that modulate mechanisms of action involved in the muscle contraction process, increased energy expenditure, insulin signaling pathway, carbohydrate metabolism, and scavenging free radicals. These functions are crucial for aerob

7. Nonlocal continuum mechanics formulation for axial, flexural, shear and contraction coupled wave propagation in single walled carbon nanotubes
This paper presents the effect of nonlocal scaling parameter on the coupled i.e., axial, flexural, shear and contraction, wave propagation in single-walled carbon nanotubes (SWCNTs). The axial and transverse motion of SWCNT is modeled based on first order shear deformation theory (FSDT) and thickness contraction. The governing equations are derived based on

8. Estudo das alterações no volume muscular, na função articular e na marcha de hemiparéticos crônicos
This work consists of two studies. The aim of the first study was to investigate quadriceps and hamstring muscle volumes and strength deficits of the knee extensors and flexors in people with chronic hemiparesis compared to a healthy group. Fifteen individuals with chronic stroke and fifteen healthy individuals took part in this study. Motor function, quadri

9. Ensaios de ondas ultrassônicas e redes neurais artificiais na avaliação da resistência à compressão do concreto
Stripping of formworks in reinforced concrete structures can only be done when concrete is hardened enough to carry the loads without generating unacceptable deformations. These are two important demands from Brazilian Code NBR 14931-2004. To get those conditions the structural design engineer should inform the building engineer the minimum values of compres

10. Os efeitos de diferentes tipos de treinamento contra resistÃncia na hipertrofia muscular em homens idosos
Objective: the present study aimed at determining whether high speed (HS) resistance training is more effective than low speed (LS) training to induce muscle hypertrophy in elderly men. Methods: Twenty elderly men (aged between 69 and 76 years) were divided in two groups: LS training (n = 9) and HS training (n = 11). The volunteers engaged in resisted traini

11. Assessment of urodynamic bladder behavior on filling with solutions representing physiological extremes of urinary osmolarity
OBJECTIVE: Verify if there is any difference in sensitive and motor bladder response in the presence of solutions with different osmolarities, simulating physiological extremes of urinary osmolarity. MATERIALS AND METHODS: Thirty-three patients (24 men and 9 women) with mean age of 46.4 years (8 to 87 years) took part in this study. They were all subjected t

12. Efeitos do treinamento resistido de potência nas habilidades funcionais muscular em homens idosos
Objetivo: o objetivo do presente estudo foi o de determinar se o treinamento contra-resistência de AV (alta velocidade) de contração é mais eficaz do que o treinamento de BV (baixa velocidade) na melhoria da força muscular e das habilidades funcionais em homens idosos, com idade entre 60 e 76 anos. Métodos: 20 homens idosos participaram do estudo, divi
