1. Extracranial non-vestibular head and neck schwannomas: a case series with the review of literature
Abstract Introduction: Schwannomas are tumous that arise from Schwann cells. Schwannoma is one of the differential diagnosis for lateral neck swelling. Objective: In this study, we aim to describe the incidence, presenting clinical features and management of extracranial, non-vestibular schwannomas of head and neck region, along with the review of the lite

2. Palatal Schwannoma: An Analysis of 45 Literature Reports and of an Illustrative Case
Abstract Introduction Schwannomas are benign tumors originating from differentiated Schwann cells. Being the least common intraoral neoplasm of neural origin, it is rarely seen in the palate. The literature lacks an extensive review of intraoral schwannoma confined to the palate. Objective To review previously reported cases of palatal schwannoma along w

3. Fibrosis: a distinguishing feature in the pathology of neural leprosy
BACKGROUND Fibrosis in the peripheral nerve is the end stage of leprous neuropathy and the cause of the resulting permanent neural function impairments. Preventive measures to avoid this irreversible pathological state are a relief strategy for leprosy sufferers. OBJECTIVES The present study describes the frequency of fibrosis along with its characterisa

4. 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

5. 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

6. Tetramethylpyrazine protects Schwann cells from ischemia-like injury and increases cell survival in cold ischemic rat nerves
Tetrametilpirazina (TMP), o principal componente do extrato de Ligusticum wallichi Franchat (erva chinesa), apresenta propriedades neuroprotetoras na isquemia. Nesse estudo, avaliamos seus efeitos protetores nas células de Schwann (SC), cultivando-as na presença de condições de depleção de oxigênio da glicose (OGD) e medindo a sobrevivência dos nervo

7. Propentofylline reverses delayed remyelination in streptozotocin-induced diabetic rats
Objective The diabetic state induced by streptozotocin injection is known to impair oligodendroglial remyelination in the rat brainstem following intracisternal injection with the gliotoxic agent ethidium bromide (EB). In such experimental model, propentofylline (PPF) recently showed to improve myelin repair, probably due to its neuroprotective, antiinflamm

8. Examining ERBB2 as a candidate gene for susceptibility to leprosy (Hansen’s disease) in Brazil
Leprosy remains prevalent in Brazil. ErbB2 is a receptor for leprosy bacilli entering Schwann cells, which mediates Mycobacterium leprae-induced demyelination and the ERBB2 gene lies within a leprosy susceptibility locus on chromosome 17q11-q21. To determine whether polymorphisms at the ERBB2 locus contribute to this linkage peak, three haplotype tagging sin

9. Atypical Manifestation of Vestibular Schwannoma
Introduction Vestibular schwannoma (also known as acoustic neuroma) is a benign tumor whose cells are derived from Schwann sheaths, which commonly occurs from the vestibular portion of the eighth cranial nerve. Furthermore, vestibular schwannomas account for ∼8% of intracranial tumors in adults and 80 to 90% of tumors of the cerebellopontine angle. Its

10. Regeneração do ramo mandibular do nervo facial de ratos após a implantação de células multipotentes do estroma mesenquimal indiferenciadas e diferenciadas in vitro que apresentam fenótipo de células de Schwann / Regenereation of the mandibular branch of rats\ facial nerve regenereation after implanting undifferenciated mesenchymal stromal multipotent cells and differenciated Schwann-like cells in vitro
INTRODUÇÃO: O nervo facial desempenha um papel importante em diversas funções fisiológicas no organismo, no entanto, distúrbios funcionais desse nervo podem também afetar a psique do indivíduo, provocando mudanças significativas na autoimagem, interferindo no rendimento profissional e piorando a qualidade de vida. Lesões graves do nervo facial (neu

11. Células-tronco da medula óssea e do tecido adiposo na regeneração do nervo ulnar em equinos / Bone marrow and adipose tissue stem cells in equine ulnar nerve regeneration
Este trabalho teve por objetivo avaliar a regeneração do nervo ulnar de equinos, submetidos à neurotomia, tubulização com tubo de silicone e terapia celular com fração de células mononucleares da medula óssea (FCM) ou células-tronco mesenquimais do tecido adiposo (ADSC). Foram utilizados 15 equinos adultos alocados em três grupos, com cinco animai

12. Deciphering the contribution of lipid droplets in leprosy: multifunctional organelles with roles in Mycobacterium leprae pathogenesis
Leprosy is an infectious disease caused by Mycobacterium leprae that affects the skin and nerves, presenting a singular clinical picture. Across the leprosy spectrum, lepromatous leprosy (LL) exhibits a classical hallmark: the presence of a collection of M. leprae-infected foamy macrophages/Schwann cells characterised by their high lipid content. The signifi
