13. Efeito do plasma rico em plaquetas e da eritropoietina na regeneração do nervo ciático de ratos wistar
Injuries to the peripheral nervous system present a challenge for regenerative medicine. The study investigated the effects of platelet-rich plasma (PRP) and erythropoietin (EPO), alone or in combination, in the regeneration of peripheral nerve in rats. The work was developed in three phases using 70 rats. The first phase, evaluated the platelet concentratio

14. Mobilização neural em rato Wistar reverte comportamento e mudanças celulares que caracterizam a dor neuropática. / Neural mobilization reverses behavioral and cellular changes that characterize neuropathic pain in rats Wistar.
The Neural Mobilization technique is a noninvasive method that has proved clinically effective in reducing pain sensitivity and consequently in improving quality of life after neuropathic pain. The present study examined the effects of Neural Mobilization (MOB) on pain sensitivity induced by chronic constriction injury (CCI) in rats. The CCI was performed on

15. Cutaneous lesions sensory impairment recovery and nerve regeneration in leprosy patients
It is important to understand the mechanisms that enable peripheral neurons to regenerate after nerve injury in order to identify methods of improving this regeneration. Therefore, we studied nerve regeneration and sensory impairment recovery in the cutaneous lesions of leprosy patients (LPs) before and after treatment with multidrug therapy (MDT). The skin

16. EFEITO DO FATOR DE CRESCIMENTO DO NERVO (NGF), FATOR DE CRESCIMENTO DE FIBROBLASTO-10 (FGF-10) E INSULINA SOBRE O DESENVOLVIMENTO IN VITRO DE FOLÍCULOS PRÉ-ANTRAIS CAPRINOS / EFFECT OF NERVE GROWTH FACTOR (NGF), FACTOR Fibroblast growth-10 (FGF-10) AND INSULIN ON DEVELOPMENT OF IN VITRO PREANTRAL FOLLICLES GOATS
Os objetivos deste estudo foram: 1) avaliar o efeito da adição de diferentes concentrações do fator de crescimento do nervo (NGF), fator de crescimento de fibroblasto-10 (FGF-10) e insulina na sobrevivência, ativação e crescimento in vitro de folículos pré-antrais caprinos cultivados inclusos em fragmentos de tecido ovariano, e 2) investigar os efei

17. Serum levels of brain-derived neurotrophic factor and thiobarbituric acid reactive substances in chronically medicated schizophrenic patients : a positive correlation / Níveis séricos do fator neurotrófico derivado do cérebro e dos produtos de reação com o ácido tiobarbitúrico em pacientes com esquizofrenia cronicamente medicados : correlação positiva
Objetivo: As neurotrofinas, enzimas antioxidantes e marcadores de oxidação têm interações. Este estudo verificou se existem correlações entre os níveis séricos de superóxido-dismutase, uma enzima chave na defesa antioxidante, os produtos de reação com o ácido tiobarbitúrico, um indicador direto de peroxidação lipídica, e o fator neurotrófic

18. Differential role of entorhinal and hippocampal nerve growth factor in short- and long-term memory modulation
We studied the effects of infusion of nerve growth factor (NGF) into the hippocampus and entorhinal cortex of male Wistar rats (250-300 g, N = 11-13 per group) on inhibitory avoidance retention. In order to evaluate the modulation of entorhinal and hippocampal NGF in shortand long-term memory, animals were implanted with cannulae in the CA1 area of the dorsa

19. TNF and NGF involvement in the nerve damage of leprosy. / Envolvimento do TNF e do NGF na lesão neural da hanseníase.
O dano nervoso, característico da hanseníase, é causa de deformidade nos pacientes e está diretamente relacionado à invasão das células de Schwann (CS) pelo Mycobacterium leprae (M. leprae). Já foi descrito que o sítio de lesão do nervo é rico em mediadores extracelulares incluindo citocinas, fatores de crescimento e proteases sendo altamente regu

20. Comparison of the effect of ganglioside GM1 and the Nerve Growth Factor (NGF) on the expression of receiver of high affinity for NGF, TrkA and insulin in isolated pancreatic islets of NOD mice (non obese diabetic) / Comparação dos efeitos do gangliosideo GM1 e do fator de crescimento neural (NGF) sobre a expressão de receptor de alta afinidade para NGF, TrkA e insulina em ilhotas pancreaticas isoladas de camundongos NOD (diabetico não obeso)
The non-obese diabetic mice (NOD) lineage is characterized by developing type 1 diabetes mellitus (DM-1) naturally, bearing a similarity to DM-1 in human beings. The spontaneous manifestation of diabetes is characterized by gradual infiltration in pancreatic islets by mononuclear cells lymphocytes T (CD4+ and CD8+) and destruction of the ß-cells producers o

21. Effects of GM1 administration on autoimmune diabetes modulation and cytokines expression, Nerve Growth Factor and TrkA receptor in NOD mice (non obese diabetic) / Avaliação dos efeitos da administração do gangliosideo GM1 na modulação do diabetes mellitus autoimune e expressão de citocinas, Nerve Growth Factor e seu receptor TrkA em camundongos NOD (non obese diabetic)
The strain of NOD mice (non obese diabetic) spontaneously develops diabetes mellitus type 1 (DM-1) with strong similarity to the observed in humans. In this model, the diabetes manifestation occurs among 12th and 24th weeks of life, with presence of pancreas-specific autoantibodies. Great part of the cells are CD4+ and CD8+T cells, and even so NK cells, lymp

22. An immunohistochemical, clinical and electroneuromyographic correlative study of the neural markers in the neuritic form of leprosy
The nerve biopsies of 11 patients with pure neuritic leprosy were submitted to routine diagnostic procedures and immunoperoxidase staining with antibodies against axonal (neurofilament, nerve growth factor receptor (NGFr), and protein gene product (PGP) 9.5) and Schwann cell (myelin basic protein, S-100 protein, and NGFr) markers. Two pairs of non-adjacent h

24. Role of sensory nervous system vasoactive peptides in hypertension
The goal of the present research was to elucidate the roles and mechanisms by which the sensory nervous system, through the actions of potent vasodilator neuropeptides, regulates cardiovascular function in both the normal state and in the pathophysiology of hypertension. The animal models of acquired hypertension studied were deoxycorticosterone-salt (DOC-sa
