13. Immobilization and therapeutic passive stretching generate thickening and increase the expression of laminin and dystrophin in skeletal muscle
Extracellular matrix and costamere proteins transmit the concentric, isometric, and eccentric forces produced by active muscle contraction. The expression of these proteins after application of passive tension stimuli to muscle remains unknown. This study investigated the expression of laminin and dystrophin in the soleus muscle of rats immobilized with the

14. Web-based neuromuscular simulator applied to the teaching of principles of neuroscience
INTRODUCTION: The learning of core concepts in neuroscience can be reinforced by a hands-on approach, either experimental or computer-based. In this work, we present a web-based multi-scale neuromuscular simulator that is being used as a teaching aid in a campus-wide course on the Principles of Neuroscience. METHODS: The simulator has several built-in indivi

15. Effects of low-intensity pulsed ultrasound on injured skeletal muscle
BACKGROUND: Low-intensity pulsed ultrasound (LIPUS) has been shown to stimulate tissue metabolism and accelerate muscle healing. However, the optimal parameters in the use of LIPUS are still not clear. OBJECTIVE: The aim of this study was to analyze the effects of LIPUS on muscle healing in rats subjected to a cryolesion. METHOD: Twenty rats were d

16. Mecanismos de proteção da distrofia muscular : estudo proteômico e terapia farmacológica / Protective mechanisms of muscular dystrophy : proteomic study and pharmacological therapy
In Duchenne Muscular Dystrophy (DMD) and in the mdx mice model of DMD, the lack of dystrophin leads to muscle degeneration. The pathogenesis of DMD is related to sarcolemmal fragility, mechanical stress and increased influx of calcium in muscle fibers, due to dysfunction of ion channels, such as the stretch-activated calcium channels. The knowledge of the pr

17. Pulsed ultrasound therapy accelerates the recovery of skeletal muscle damage induced by Bothrops jararacussu venom
We studied the effect of pulsed ultrasound therapy (UST) and antibothropic polyvalent antivenom (PAV) on the regeneration of mouse extensor digitorum longus muscle following damage by Bothrops jararacussu venom. Animals (Swiss male and female mice weighing 25.0 ± 5.0 g; 5 animals per group) received a perimuscular injection of venom (1 mg/kg) and treatment

18. Análise do papel da proteína quinase ativada pela AMP (AMPK) na hipertrofia do cardiomiócito induzida pelo hormônio tiroideano. / Role of AMP-activated protein kinase (AMPK) in the cardiomyocyte hypertrophy induced by thyroid hormone.
Estudos recentes demonstram que o Hormônio Tiroideano (HT) é capaz de modular rapidamente o estado de fosforilação de proteínas quinases relacionadas ao processo de hipertrofia cardíaca. Evidências experimentais indicam que a proteína quinase ativada por AMP (AMPK) seja um alvo importante no controle do crescimento hipertrófico, uma vez que a ativa�

19. Fibrose muscular em camundongo mdx : efeitos do exercício físico e de agente anti-fibrótico / : Prevention of muscle fibrosis and myonecrosis in mdx mice by suramin, a TGF-beta1 blocker
The mdx mouse is commonly used as a model to study Duchenne muscular dystrophy (DMD) however shows cycles of muscle regeneration and reduced fibrosis. The purposes of this study were (1) to induce muscle fibrosis through eccentric running exercise in mdx mice and (2) to verify the effects of suramin on muscle fibrosis. Six-month-old mdx (n=42) and control (C

20. Description of Sidneioides peregrinus sp. nov. (Tunicata: Ascidiacea: Polyclinidae): a possible exotic species in the Atlantic Ocean
Three species of Sidneioides Kesteven, 1909 were known until now, all of them from the western Pacific. Sidneioides peregrinus is a new species we found in Paranaguá Bay, southern Brazil. Diagnostic characteristics of the species are: colonies with 1-5 lobes, closely clumped, and attached by the entire basal area or by a common smaller area; seven to ten th

21. FONOFORESE E ELETROESTIMULAÇÃO NEUROMUSCULAR EM CÃES: UMA CONTRIBUIÇÃO PARA A FISIOTERAPIA VETERINARIA / PHONOPHORESIS AND NEUROMUSCULAR ELECTRICAL STIMULATION IN DOGS: A CONTRIBUTION TO THE VETERINARY PHISIOTHERAPY
The aim of the first study was to evaluate the plasma concentration of diclofenac sodium (DS) in dogs submitted to diclofenac phonophoresis and to evaluate if phonophoresis induces greater absorption of this drug. .Five dogs were used in eight different groups at different times: Group 1, application of ultrasound for six minutes, removal of the ultrasound g

22. Evaluation of the electromyographic signal and the histomorphometry of vastus lateralis muscle in different electrodes placement, intensities of contraction and genders / Avaliação do sinal eletromiografico e da histomorfometria do musculo vasto lateral em diferentes posicionamentos de eletrodos, intensidades de contração e generos
It has been shown that electromyography signal (EMGs) and histomorphometry are different along the muscle belly and between genders, although the relationship between these parameters is not clear. The aim of this study was to evaluate the EMGs in different intensities of volunteer isometric muscle contraction (10-100%) and electrodes positions over the bell

Temporomandibular disfunction (TMD) is a colletive term that refers to different clinical problems of the temporomandibular joint and the jaw muscles. These disfunctions are characterizied meanly by pain, joint sounds and irregular or limited mandibular function. The jaw muscles can be involved in the TMD of muscle etiology, and by definition they are the on
