1. Safety of local anesthetics,
Abstract Local anesthetics are essential medications for the conduction of dermatological procedures. They stop the depolarization of nerve fibers and are divided into two main categories, the amide and ester types. Systemic toxicity with reflex on the central nervous and cardiovascular systems is their most feared adverse reactions, and the anaphylactic rea

2. THE ACTION OF SERICIN PROTEIN ON INITIAL NERVE REPAIR, ASSOCIATED OR NOT WITH SWIMMING IN WISTAR RATS
RESUMO Objetivo: Analisar os efeitos do tratamento da sericina, associada ou não ao exercício de natação com sobrecarga, sobre o reparo inicial do nervo isquiático após compressão em ratos Wistar. Métodos: Foram separados 40 animais em cinco grupos, sendo eles: controle; lesão; lesão-sericina; lesão-natação e lesão-sericina-natação. Durante

3. Sciatic nerve and its variations: is it possible to associate them with piriformis syndrome?
RESUMO O nervo isquiático forma-se a partir das raízes do plexo lombosacro e emerge da pelve passando inferiormente ao músculo piriforme, em direção ao membro inferior onde se divide em nervos tibial e fibular comum. Variações anatômicas relativas ao local onde ocorre a divisão desse nervo, bem como do seu trajeto, parecem ser fatores relacionados �

4. Síndrome de Tolosa-Hunt, uma oftalmoplegia dolorosa
Resumo A síndrome de Tolosa-Hunt (STH) é uma doença rara caracterizada por oftalmoplegia dolorosa unilateral de início súbito causada por uma inflamação granulomatosa inespecífica no seio cavernoso ou fissura orbital superior (ou ambos). A oftalmoparesia ocorre quando os nervos cranianos III, IV e VI são acometidos pela inflamação. Disfunções pu

5. Small Fiber Neuropathy in Fabry Disease: a Review of Pathophysiology and Treatment
Abstract Fabry disease is an inherited metabolic disorder characterized by progressive lysosomal accumulation of glycolipids in a variety of cell types, including neural cells. Small, unmyelinated nerve fibers are particularly affected and small fiber peripheral neuropathy often clinically manifests at a young age. Neuropathic pain and pain attacks are often

6. Morphological and nociceptive effects of mechanical vibration on the sciatic nerve of oophorectomized Wistar rats
Abstract Aim: To evaluate the effects of whole-body vibration in the sciatic nerve of oophorectomized Wistar rats, on nociceptive and morphological parameters, such as fiber, axon, and myelin sheath diameters, G ratio, number of nerve fiber and nuclei of Schwann cells, and percentage of connective tissue. Method: Sixty-four rats were used in the groups sha

7. Síndrome de Pierre Robin associada à Síndrome de Duane familiar do tipo III
Resumo A síndrome de Pierre Robin (PRS) consiste em uma tríade de anomalias caracterizada por micrognatia, glossoptose e fissura de palato, comumente associada com outras síndromes e ocasionalmente com alterações oculares. Na Síndrome de Duane (DRS), há uma falha na inervação do reto lateral pelo VI nervo, com inervação anômala do reto lateral po

8. 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

9. Protein and mRNA expression of gonadotropin-releasing hormone receptor in yaks during estrus
ABSTRACT To demonstrate the role of gonadotropin-releasing hormone (GnRH) in yaks (Bos grunniens), we characterized the expression of gonadotropin-releasing hormone receptor (GnRHR) mRNA and protein. The level of GnRHR mRNA in the hypothalamus was higher than that in the pineal gland, pituitary gland, and ovary during estrus. Immunofluorescence analysis show

10. 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

11. 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

12. Rescuing axons from degeneration does not affect retinal ganglion cell death
After a traumatic injury to the central nervous system, the distal stumps of axons undergo Wallerian degeneration (WD), an event that comprises cytoskeleton and myelin breakdown, astrocytic gliosis, and overexpression of proteins that inhibit axonal regrowth. By contrast, injured neuronal cell bodies show features characteristic of attempts to initiate the r
