1. Two birds, one stone: a surgical approach for third nerve palsy with aberrant regeneration
RESUMO A regeneração aberrante nas paralisias do terceiro nervo, ligando a contração do reto medial ao músculo levantador da pálpebra, é uma grande oportunidade para fazer um planejamento cirúrgico para tratar tanto a ptose quanto o desvio horizontal em um procedimento único. Relatamos uma ptose grave associada à exotropia corrigida com sucesso com

2. Effect of Tacrolimus and Cyclosporine Immunosuppressants on Peripheral Nerve Regeneration: Systematic Review and Meta-analysis
Resumo As lesões nervosas periféricas são uma causa importante de busca por atendimento médico. Elas ocorrem quando há a interrupção da continuidade das estruturas e do bloqueio da propagação dos impulsos nervosos, afetando a capacidade funcional dos indivíduos. Para avaliar os efeitos dos imunossupressores tacrolimus e ciclosporina na regeneraçã

3. Effects of titanium prepared platelet rich fibrin on facial nerve regeneration: an experimental study
Resumo Introdução: A lesão do nervo facial é uma condição que causa problemas funcionais, psicológicos e cosméticos e os métodos de tratamento precisam ser melhorados. Objetivo: Investigamos a eficácia da fibrina rica em plaquetas preparada com titânio como um intensificador de cura na transecção do nervo facial. Método: Vinte e sete coelhos

4. Exosomes secreted from miRNA-29b-modified mesenchymal stem cells repaired spinal cord injury in rats
Exosomes, a kind of extracellular vesicle, are promising therapeutic agents for spinal cord injury (SCI). This article aimed to investigate effects of exosomes secreted from miRNA-29b-modified bone marrow mesenchymal stem cells (BMSCs) on SCI. Exosomes were extracted from BMSCs transfected with miRNA-29b or negative control (miR NC). SCI rats were injected i

5. Monitorização de células-tronco mesenquimais injetadas via retrobulbar próximas ao nervo óptico lesados de coelhos
Resumo Objetivo: Verificar a presença das células-tronco mesenquimais (MSC) na área próxima ao nervo óptico de coelhos previamente lesado com álcool absoluto. Métodos: Os 12 coelhos da raça Nova Zelândia foram distribuídos em 2 lotes. Após sedação, cada olho do animal recebeu uma injeção retrobulbar de 1 ml de álcool absoluto em um dos olho

6. Transcriptomic differential lncRNA expression is involved in neuropathic pain in rat dorsal root ganglion after spared sciatic nerve injury
Dorsal root ganglia (DRG) neurons regenerate spontaneously after traumatic or surgical injury. Long noncoding RNAs (lncRNAs) are involved in various biological regulation processes. Conditions of lncRNAs in DRG neuron injury deserve to be further investigated. Transcriptomic analysis was performed by high-throughput Illumina HiSeq2500 sequencing to profile t

7. Combination of heterologous fibrin sealant and bioengineered human embryonic stem cells to improve regeneration following autogenous sciatic nerve grafting repair
Abstract Background Peripheral nerve injury is a worldwide clinical problem, and the preferred surgical method for treating it is the end-to-end neurorrhaphy. When it is not possible due to a large nerve gap, autologous nerve grafting is used. However, these surgical techniques result in nerve regeneration at highly variable degrees. It is thus very importa

8. Inside-out and standard vein grafts associated with platelet-rich plasma (PRP) in sciatic nerve repair. A histomorphometric study
Abstract Purpose: To evaluated the tubulization technique with standard and inside-out vein, filled or not with platelet-rich plasma (PRP), in sciatic nerve repair. Methods: Seventy male Wistar rats were randomly divided into five groups: IOVNF (Inside-Out Vein with No Filling); IOVPRP (Inside-Out Vein filled with PRP); SVNF (Standard Vein with No Fillin

9. Retinoic acid protects from experimental cerebral infarction by upregulating GAP-43 expression
The aim of this study was to investigate whether exogenous retinoic acid (RA) can upregulate the mRNA and protein expression of growth-associated protein 43 (GAP-43), thereby promoting brain functional recovery in a rat distal middle cerebral artery occlusion (MCAO) model of ischemia. A total of 216 male Sprague Dawley rats weighing 300–320 g were divided

10. N-acetylcysteine downregulates phosphorylated p-38 expression but does not reverse the increased superoxide anion levels in the spinal cord of rats with neuropathic pain
We determined the effect of N-acetylcysteine (NAC) on the expression of the phosphorylated p38 (p-p38) protein and superoxide anion generation (SAG), two important players in the processing of neuropathic pain, in the lumbosacral spinal cord of rats with chronic constriction injury (CCI)-induced neuropathic pain. The sciatic functional index (SFI) was also m

11. Effect of ozone and methylprednisolone treatment following crush type sciatic nerve injury
ABSTRACT PURPOSE: To assess and compare the histopathological effects of ozone therapy and/or methylprednisolone (MPS) treatment on regeneration after crush type sciatic nerve injury. METHODS: Forty Sprague-Dawley male rats were randomly allocated into four groups. Four groups received the following regimens intraperitoneally every day for 14 days after f

12. Heregulin-1β Promotes the Synergistic Effect Between Allogenic Skin-Derived Precursor Differentiated Schwann Cells (SKP-SC) and Acellular Nerve Allograft (ANA) in Peripheral Nerve Regeneration Through Inhibiting Mir-21
Previous studies in our lab found that heregulin-1β with SKP-SCs (neurons and Schwann cells differentiated from SKPs) / ANA (acellular nerve allograft) transplantation represented a powerful therapeutic approach, and facilitates the efficacy of ANA in peripheral nerve injury. In this study, our purpose is to explore the mechanism between them. Firstly we tr
