13. Enxerto sintético e biológico, com e sem preenchimento de veia jugular externa, no reparo de nervo periférico em ratos / Syntetic and biological graft, filled with the external jugular vein in the repair of peripheral nerve in rats
Despite the development of technology involved in peripheral nerve regeneration, there is no technique that presents a recovery of the nervous tissue with completely satisfactory results. This fact arouses interest of several researchers around the word. Although the autologous nerve grafting is the current gold standard for the repair of large nerve gaps, o

14. Células mononucleares autólogas de medula óssea na regeneração do nervo tibial em coelhos / Autologous mononuclear cells from bone marrow in the regeneration of tibial nerve in rabbits
The regeneration of peripheral nerves after injury has been target in researches for new technologies that lead to good results, so as to get completely restoration of nerve function. For such, many techniques have been developed using synthetic materials associated to exogenous factors that enhance the regeneration process, as mononuclear cells of bone marr

15. Thermographic evaluation of hind paw skin temperature and functional recovery of locomotion after sciatic nerve crush in rats
INTRODUCTION: Peripheral nerves are often damaged by direct mechanical injury, diseases, and tumors. The peripheral nerve injuries that result from these conditions can lead to a partial or complete loss of motor, sensory, and autonomic functions, which in turn are related to changes in skin temperature, in the involved segments of the body. The aim of this

16. Alterations of morphology, mechanical and osteogenic capacity of mdx mice bones / Alterações da morfologia, resistência mecânica e capacidade osteogênica dos ossos de camundongos mdx
Duchenne muscular dystrophy (DMD) is a neuromuscular disease caused by lack of dystrophin. DMD patients have brittle bones because of muscle weakness and use of glucocorticoids. The mdx mouse is widely used as experimental model for the study of DMD and it presents lack of dystrophin, intense inflammatory process and muscle fiber degeneration. Moreover, it p

17. INFLUÊNCIA DE DIFERENCIADOS EXERCÍCIOS FÍSICOS NA REGENERAÇÃO DO NERVO CIÁTICO DE RATOS: estudo funcional e morfológico. / INFLUENCE OF DIFFERENCED PHYSICAL EXERCISES IN ISCHIATIC NERVE REGENERATION IN RATS: functional and morphological study.
Peripheral nerve fibers are a frequent lesion target because of its distribution around organism. These lesions create motor, sensitive and autonomic alterations. Several experimental studies demonstrate a relationship between physical exercise practice and functional regeneration after a peripheral nerve lesion. However, studies that relates the metabolic w

18. Emprego do colageno com organização supramolecular na regeneração nervosa periferica in vitro e in vivo / Influence of a naturally supraorganized collagen on the peripheral nerve regeneration in vitro and in vivo
The present study investigated in vitro and in vivo the influence of naturally supraorganized collagen on the peripheral nerve regeneration. In the in vitro study, Schwann cells (SCs) were seeded on naturally supraorganized collagen membranes and evaluated with immunocytochemistry and scanning electron microscopy. The results revealed that SCs kept the expre

19. Influence of the number of stitches in axonal regeneration and production of extracellular matrix in end-to-end epineural suture in the rat sciatic nerve / Influência do número de pontos na regeneração axonal e produção de matriz extracelular na sutura epineural terminoterminal no nervo ciático do rato
PURPOSE: After an injury to a peripheral nerve, its repair is performed with epineural sutures of the stumps using nylon. The inflammatory process caused by the passage of the needle and the presence of suture material with the consequent formation of scar tissue at the suture line becomes an obstacle to axonal regeneration after nerve repair. In the literat

20. Vein graft fulfilled with fat in peripheral nerve repair: a new proposal / Enxerto venoso preenchido com gordura no reparo de nervo periférico: uma nova proposta
With technology advance and the resultant production of more sophisticated equipment, microsurgery has been obtaining more attention in the experimental investigation field referred to peripheral nerves repair. It is know that in case of simple nerve section, without tissue loss, the end-to-side-neurorraphy is the most recommended technique. However, in each

21. Utilização de células mononucleares da medula óssea na regeneração do nervo ciático de ratos após neurorrafia
Peripheral nerves injuries are frequent and can result in permanent loss of function. Currently, cell therapy constitutes a great possibility of improving nerve regeneration, increasing the success of the nerve repair. Objective: To evaluate the use of mononuclear cells in the regeneration process of the sciatic nerve after its section and followed by end-to

22. The effects of low power laser irradiation on the regeneration of the common fibular nerve in rat submitted to a crush lesion. / Os efeitos da irradiação com laser de baixa potência na regeneração do nervo fibular comum do rato submetido a lesão por esmagamento
Peripheral nerve regeneration is a natural process, which requires a long period to complete, with a few evidences that physical agents including laser, can speed it up. The main objective of this investigation was to analyze the influence of low power laser (AsGaAL) irradiation on nerve regeneration, in a model of crush injury of the common fibular nerve of

23. Ação da laserterapia de baixa intensidade (830nm) na regeneração muscular de ratos idosos
The elderly still go through physical changes, especially musculoskeletal disorders such as sarcopenia, changes in central and peripheral nervous system, blood hypoperfusion, regenerative changes contributing to atrophy and muscle weakness, undermining the activities of daily living (AVL). The regenerative process happens about the determination, proliferati

24. AvaliaÃÃo morfomÃtrica da regeneraÃÃo nervosa perifÃrica em animais desnutridos precocemente
The study evaluated the peripheral nerve regeneration in adult animals that were submitted to protein malnutrition during the period known as the critical window of development. We used 20 male rats, adult, Wistar line. During the period of lactation, parts of the mothers received diet hypoproteic (casein 8%) forming the group of malnourished pups (10 animal
