1. Effects of the platelet-rich fibrin associated with physical exercise in a model of median nerve compression.
Abstract AIMS Platelet-Rich Fibrin (PRF) is a new and promising technique for tissue repair, however, there is still a gap about its action on peripheral nerve injury, as well as its association with physical exercise. Thus, the aim of this study was to evaluate the effects of the PRF associated with physical exercise in a model of median nerve compression.

2. 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

3. Morphometric analysis of the phrenic nerve in male and female Wistar-Kyoto (WKY) and spontaneously hypertensive rats (SHR)
Ventilatory differences between rat strains and genders have been described but the morphology of the phrenic nerve has not been investigated in spontaneously hypertensive (SHR) and normotensive Wistar-Kyoto (WKY) rats. A descriptive and morphometric study of the phrenic nerves of male (N = 8) and female (N = 9) SHR, and male (N = 5) and female (N = 6) WKY i

4. 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

5. The effect of the therapeutical ultrasound in the treatment of the injuries for crushing of the ciático nerve of rats / Os efeitos do ultra-som terapêutico no tratamento das lesões por esmagamento do nervo ciático de ratos
An experimental study of the influence of therapeutic ultrasound on the regeneration of the sciatic nerve submitted to controlled crush injury was carried out in rats. Twenty female Wistar rats weighing 250 g on average were used and distributed in two groups according to the procedure: 1) crush injury only, ten rats; 2) crush injury followed by ultrasound i

6. Estudo da viabilidade de enxertos de nervos mantidos em soluções conservadoras
Traumatic lesions are very often on peripheral nervous system, and have reserved prognostic when a loss important nerve segment occurs. However, the knowledge about the cellular and the molecular events promoting the nerve regeneration, besides the use of microsurgical techniques, gives a better perceptive to improve the peripheral nerve repair nowadays. In

7. Noradrenergic parenchymal nerve fiber branching after cold acclimatisation correlates with brown adipocyte density in mouse adipose organ
The mammalian adipose organ is composed of subcutaneous and visceral depots containing white and brown adipocytes. Cold acclimatisation induces an increase in the brown component without affecting the overall number of adipocytes; this form of plasticity is associated to obesity and diabetes resistance in experimental models. Cold activates the drive of the

8. Immunohistochemical demonstration of choline acetyltransferase-immunoreactive preganglionic nerve fibers in guinea pig autonomic ganglia.
The distribution of choline acetyltransferase (ChoAcTase)-like immunoreactivity in the superior cervical ganglion and the stellate ganglion was analyzed with immunohistochemistry. A dense network of ChoAcTase-immunoreactive nerve fibers was observed in both ganglia studied. The ChoAcTase-positive fibers were found in all parts of the ganglia but had a differ

9. Structural alterations of nerve during cuff compression.
Whether compression nerve injury is due to ischemia, direct mechanical injury, or both remains unsettled. To assess structural changes of nerve during compression, peroneal nerves of rats were compressed at various pressures for different times, and the structural alterations were stopped by simultaneous in situ and perfusion fixation. The structural changes

10. Recombinant human nerve growth factor is biologically active and labels novel high-affinity binding sites in rat brain.
Iodinated recombinant human nerve growth factor (125I-rhNGF) stimulated neurite formation in PC12 cell cultures with a half-maximal potency of 35-49 pg/ml, compared with 39-52 pg/ml for rhNGF. In quantitative ligand autoradiography, the in vitro equilibrium binding of 125I-rhNGF to brain sections showed a 10-fold regional variation in density and was saturab

11. Brain-derived neurotrophic factor-deficient mice develop aggressiveness and hyperphagia in conjunction with brain serotonergic abnormalities
Brain-derived neurotrophic factor (BDNF) has trophic effects on serotonergic (5-HT) neurons in the central nervous system. However, the role of endogenous BDNF in the development and function of these neurons has not been established in vivo because of the early postnatal lethality of BDNF null mice. In the present study, we use heterozygous BDNF+/− mice t
