1. Eficácia da estimulação elétrica com corrente russa após neurorrafia término-lateral do nervo fibular comum: análise eletroneuromiográfica e de força muscular
RESUMO Lesões de nervos periféricos levam a perda funcional elevada no tecido muscular. Assim, muitas pesquisas têm investigado técnicas cirúrgicas, como neurorrafias, e recursos terapêuticos, como eletroestimulação, para melhorar a funcionalidade de um músculo reinervado após lesão periférica. Este estudo tem como objetivo investigar os efeitos

2. End-to-side versus end-to-end neurorrhaphy at the peroneal nerve in rats
Abstract Purpose: To evaluate three different kinds of neurorrhaphy of the peroneal nerve. Methods: Eigthy rats were divided into 5 groups. Control: nerve had no intervention. End-to-end (EE): nerve was cut and elongated with a nerve graft with two end-to-end neurorrhaphies. End-to-side (ES): nerve was cut and sutured to the graft with at the lateral sid

3. Comparative study between standard and inside-out vein graft techniques on sciatic nerve repair of rats. Muscular and functional analysis
Abstract Purpose: To compare the functional result of standart vein grafts and inside-out vein graft technique on sciatic nerve repair. Methods: We used 24 male Wistar rats divided into 4 groups: control group (CG), standard vein graft group (SVG), Inside-out vein graft group (IOVG) and denervated Group (DG). SVG, IOVG and DG underwent total section of th

4. Implantation of muscle satellite cells overexpressing myogenin improves denervated muscle atrophy in rats
This study evaluated the effect of muscle satellite cells (MSCs) overexpressing myogenin (MyoG) on denervated muscle atrophy. Rat MSCs were isolated and transfected with the MyoG-EGFP plasmid vector GV143. MyoG-transfected MSCs (MTMs) were transplanted into rat gastrocnemius muscles at 1 week after surgical denervation. Controls included injections of untran

5. Effect of electrical stimulation of the cranial tibial muscle after end-to-side neurorrhaphy of the peroneal nerve in rats
PURPOSE: To investigate the efficiency of electrical stimulation in the muscle maintenance and nerve regeneration after end-to-side neurorrhaphy (ESN). METHODS: Sixty male Wistar rats (Rattus norvegicus) were divided into four experimental groups. Control group (Control), Denervated Group (Denervated); Group with End-to-side neurorrhaphy (ESN); Group with En

6. Células satélites e fusos neuromusculares em músculos estriados de ratos desnervados por longo período / Satellite cells and neuromuscular spindles in skeletal muscles in long term denervated rats
O músculo estriado esquelético apresenta em sua constituição células satélites (CS) que se encontram em estado quiescente localizadas entre o sarcolema e a lâmina basal das fibras musculares. As CS podem ser ativadas, diferenciando em mioblastos, contribuindo para regeneração e/ou crescimento do tecido muscular. Os Fusos neuromusculares são mecanor

7. PPM1B and P-IKKβ expression levels correlated inversely with rat gastrocnemius atrophy after denervation
Activated inhibitor of nuclear factor-κB kinase β (IKKβ) is necessary and sufficient for denervated skeletal muscle atrophy. Although several studies have shown that Mg2+/Mn2+-dependent protein phosphatase 1B (PPM1B) inactivated IKKβ, few studies have investigated the role of PPM1B in denervated skeletal muscle. In this study, we aim to explore the expre

8. Expression and localization of myogenic regulatory factors (MyoD and Myogenin) in somatic rat muscle after reinervation with vein graft tubulization / Expressão e localização de fatores regulatórios miogênicos (MyoD e Miogenina) em músculos somíticos de ratos reinervados pela técnica de tubulização
Peripheral nerve injuries can result in the loss of propioception, morphological and functional alterations of muscle fibers which causes a negative impact on the quality of life. These injuries elicit an alteration on the expression of muscle specific genes, like MyoD and Myogenin, involved in the satellite cell activation and muscle mass regulation. The ve

9. Effect low-intensity pulsed ultrasound in peripheral nerve regeneration of the rats / Ultra-som pulsado de baixa intensidade na regeneração nervosa periférica de ratos
O ultra-som é uma das formas de tratamento terapêutico, não-invasivo, que pode auxiliar na regeneração nervosa periférica. Dentre todas estas técnicas não-invasivas de regeneração nervosa periférica, pouco se sabe sobre a influência do ultra-som na regeneração desse tecido. Para tanto foi realizado um trabalho experimental com o objetivo de ava

10. Influencia dos anestesicos locais no bloqueio neuromuscular produzido por diferentes bloqueadores neuromusculares : estudo experimental / The influence of local anesthetics on neuromuscular blockade produced by differents neuromusculars blockades : experimental study
Local anesthetics commonly used in clinical practice can interact with neuromuscular blockers and potentiate their effects. Many authors studied this interaction, but the mechanism involved in the potentiation of neuromuscular blockers and the action of local anesthetics in the pre and postjunctional sites were not completely elucidated- In this study, in sp

11. Effect of salbutamol on innervated and denervated rat soleus muscle
The objective of the present investigation was to perform a 14-day time-course study of treatment with salbutamol, a ß2 adrenoceptor agonist, on rat soleus muscle in order to assess fiber type selectivity in the hypertrophic response and fiber type composition. Male Wistar rats were divided into four groups: control (N = 10), treated with salbutamol (N = 30

12. Distribuição dos receptores de acetilcolina e terminais nervosos na junção neuromuscular de fibras musculares regeneradas
Mdx mice have deficiency of dystrophin and cycles of muscle fiber regeneration. Changes in the distribution of acetylcholine receptors have been reported at the neuromuscular junction of mdx and may be a consequence of muscle fiber regeneration. At the present, we verified whether the distribution of receptors is still altered in long-term regenerated muscle
