25. Correlação entre densidade de fibras nervosas em biópsia de pele e teste de quantificação da sensibilidade térmica em pacientes com hanseníase
It is known that, in lesions of leprosy, loss of tactile sensitivity, mediated by thick myelinated A-beta type nerve fibers, is preceded by the loss of thermal sensitivity, mediated by thin myelinated A-delta type and thin unmyelinated C type thin fibers, which makes the evaluation of the thermal sensitivity of a suspicious lesion a fundamental criterion for

26. Effect of neurotrophic factor, MDP, on rats’ nerve regeneration
Our objective was to determine the immune-modulating effects of the neurotrophic factor N-acetylmuramyl-L-alanyl-D-isoglutamine (MDP) on median nerve regeneration in rats. We used male Wistar rats (120-140 days of age, weighing 250-332 g) and compared the results of three different techniques of nerve repair: 1) epineural neurorrhaphy using sutures alone (gr

27. Inactivation of capsaicin-sensitive nerves reduces pulmonary remodeling in guinea pigs with chronic allergic pulmonary inflammation
Pulmonary remodeling is an important feature of asthma physiopathology that can contribute to irreversible changes in lung function. Although neurokinins influence lung inflammation, their exact role in the extracellular matrix (ECM) remodeling remains to be determined. Our objective was to investigate whether inactivation of capsaicin-sensitive nerves modul

28. Histomorphometric and sympathetic innervation of the human internal thoracic artery
INTRODUCTION: Internal thoracic artery (ITA) is an established arterial graft for the coronary artery by-pass surgery. Special micro-anatomical features of the ITA wall may protect it from age related pathological changes. One of the complications seen after coronary artery bypass grafting is vasospasm. Sympathetic nerves may be involved in vasospasm. OBJECT

29. INFLUÊNCIA DE DIFERENCIADOS EXERCÍCIOS FÍSICOS NA REGENERAÇÃO DO NERVO CIÁTICO DE RATOS: estudo funcional e morfológico. / INFLUENCE OF DIFFERENCED PHYSICAL EXERCISES IN ISCHIATIC NERVE REGENERATION IN RATS: functional and morphological study.
Peripheral nerve fibers are a frequent lesion target because of its distribution around organism. These lesions create motor, sensitive and autonomic alterations. Several experimental studies demonstrate a relationship between physical exercise practice and functional regeneration after a peripheral nerve lesion. However, studies that relates the metabolic w

30. Emprego do colageno com organização supramolecular na regeneração nervosa periferica in vitro e in vivo / Influence of a naturally supraorganized collagen on the peripheral nerve regeneration in vitro and in vivo
The present study investigated in vitro and in vivo the influence of naturally supraorganized collagen on the peripheral nerve regeneration. In the in vitro study, Schwann cells (SCs) were seeded on naturally supraorganized collagen membranes and evaluated with immunocytochemistry and scanning electron microscopy. The results revealed that SCs kept the expre

31. Monoamines in the pedal plexus of the land snail Megalobulimus oblongus (Gastropoda, Pulmonata)
In molluscs, the number of peripheral neurons far exceeds those found in the central nervous system. Although previous studies on the morphology of the peripheral nervous system exist, details of its organization remain unknown. Moreover, the foot of the terrestrial species has been studied less than that of the aquatic species. As this knowledge is essentia

32. Correlação entre o eletrorretinograma de padrão reverso, a tomografia de coerência óptica e a perimetria automatizada na detecção da perda neural na atrofia em banda do nervo óptico / Relationship between pattern electroretinogram, optical coherence tomography and automated perimetry for detection of neural loss in eyes with band atrophy of the optic nerve
PURPOSE: To evaluate the ability of full-field and hemifield pattern electroretinogram parameters to differentiate between healthy eyes and eyes with band atrophy of the optic nerve and also to evaluate the relationship between pattern electroretinogram amplitude, macular and retinal nerve fiber layer thickness by optical coherence tomography, and visual fie

33. Microsurgical testicular denervation for the treatment of chronic testicular pain initial results
INTRODUCTION: Chronic testicular pain remains an important challenge for urologists. Currently, the treatment plan is primarily empirical, with the first approach consisting of clinical measures. However, some patients remain in pain despite a conservative treatment protocol and, for them, it is possible to perform a surgical procedure that involves severing

34. Melanin-concentrating hormone and orexin A neuropeptidergic systems in the dorsal motor nucleus of the vagus nerve in rat / Sistema neuropeptidergico do hormonio concentrador de melanina e da orexina A no nucleo motor dorsal do nervo vago em rato
Melanin-concentrating hormone (MCH) and orexin-A (OXA) are neuromediators expressed in neurons distributed in the diencephalum, mainly in the lateral hypothalamic area, projecting nerve fibers to several parts of the central nervous system. These neuropeptides exert potent orexigenic activity, increasing feeding and controlling the energetic balance. Consequ

35. AvaliaÃÃo morfomÃtrica da regeneraÃÃo nervosa perifÃrica em animais desnutridos precocemente
The study evaluated the peripheral nerve regeneration in adult animals that were submitted to protein malnutrition during the period known as the critical window of development. We used 20 male rats, adult, Wistar line. During the period of lactation, parts of the mothers received diet hypoproteic (casein 8%) forming the group of malnourished pups (10 animal

36. Mobilização neural como recurso terapêutico na recuperação funcional e morfológica do nervo ciático de ratos após lesão traumática
The present study examined the effects of Neural Mobilization (NM) in the functional sensory-motor recovery after sciatic nerve crush injury in rats. The nerve crush was performed on adult male rats, submitted to 15 sessions of passive neural mobilization treatment through a modified straight leg raise (SLR) test, with groups starting at 3 different times:1,
