Tumor maligno da bainha de nervo periférico envolvendo raízes nervosas do terceiro segmento medular lombar em um cão

Malignant peripheral nerve sheath tumors (MPNST) involving spinal nerve roots are uncommon in dogs. A nine-year old, intact, mixed-breed dog, demonstrated clinical signs of incoordination in the pelvic limbs and micturition for approximately one week. Clinical examination revealed proprioceptive deficits and bilateral patellar hyperreflexia. During exploratory celiotomy a mass was observed adhered to the lumbar vertebral segments. Medical therapy was initiated, but neurological signs were progressive, and the owner opted for euthanasia. Gross examination showed that the mass in the abdominal cavity was attached to the lumbar segments L3 and L4, causing bone lysis in L3, but showed no tumor invasion into the spinal canal. Microscopic features were characterized by prominent proliferation of ovoid and fusiform cells with poorly defined cytoplasm arranged in interlacing bundles and concentric whorls. The cells were embedded in a delicate to moderate collagenous stroma and moderate anisokariose and high mitotic activity were noted. The immunohistochemical assay showed positive staining for GFAP, S-100 protein and vimentin, and negative staining for factor VIII, α-actin and citokeratine. The definitive diagnosis of malignant peripheral nerve sheath tumor was made on the basis of the histological and immunohistochemical findings.

Modelo de Marcus, elementos de matriz de tunelamento, efeitos de solvente e controle nuclear em reações de transferência de elétrons

This paper aims to give an initial presentation to physics students of the area of electron transfer, addressing its major aspects. The subject is then presented in an introductory way, highlighting and discussing the key points. Primarily, the problem is approached in a simplified manner through a two-state system, and aspects of calculating the matrix-element are discussed. Then, the electron transfer problem, influenced by nuclear reaction coordinates, is addressed and treated by the Marcus theory. Time scales and the concepts of adiabatic and nonadiabatic phenomena are discussed in the context of electron transfer. The classical, semi-classical and quantum formalisms of for the nuclear reactions coordinates are presented, and aspects of solvents are also discussed. Finally, we conclude by examining some recent examples of problems discussed in the literature.

Fisioterapia Aquática na Transferência do Sentado para Ortostatismo no Paciente com AVC: Relato de Caso

Introduction. Studies show that 70% of body weight in patients with stroke during the transfer from sitting to standing position is transferred to the uninvolved limb. Significantly interfering with activities of daily living. Objective. The influence of aquatic therapy on eight in the affected hemisphere during the transition from sitting to standing. Method. Participated in this study a patient with right hemiparesis, the protocol lasted eight sessions in a liquid medium. The data of activation of the gluteus muscle were collected from surface electromyography and data as the weight transfer was examined by baropodometry platform. Results. Initial electromyography (151.1uv right gluteus maximus and left gluteus maximus 229.1uv) and Final electromyography (113.6 uv right gluteus maximus and left gluteus maximus113.3uv). Evolution was 19% in weight transferin paretic hemibody compared the pre and post intervention. Conclusion. The results showed that treatment was favorable to the patient, because at the end of application of the observed activation of the gluteus maximus and improved weight-bearing, and consequently these factors interfered positively in the security and independe in transferring from sitting to standing position.
