The advent and growth of technological advances have led to new routes of knowledge. Thereby, we currently face new challenges. We have just started to get a glimpse of the structural and functional role of neural stem cells in differentiation and migration processes, the origin of synaptic networks, and subsequent readjustments in specific circuits. A(More)
OBJECTIVE The trans-supraorbital approach has the advantage of combining the keyhole principle with cranial base surgery. The anatomic fields that can be visualized with the use of this procedure have been demonstrated in cadavers, and the advantages and potential surgical applications of this procedure are described in this report. This article is the(More)
Tissue engineering is an important therapeutic strategy to be used in regenerative medicine in the present and in the future. Functional biomaterials research is focused on the development and improvement of scaffolding, which can be used to repair or regenerate an organ or tissue. Scaffolds are one of the crucial factors for tissue engineering. Scaffolds(More)
OBJECTIVE To evaluate whether bilayer chitosan scaffolding (BChS) can provide a watertight dural closure and permit regeneration by fibroblasts in an experimental in vivo model. METHODS In the in vitro phase, BChS was elaborated and the following characteristics were evaluated: pore size, thickness, water absorption capacity, tensile strength, strain, and(More)
BACKGROUND The peripheral hallmarks of neurofibromatosis type 1 (NF1) are Café au lait and solid nodular neurofibromas. The morphological behavior of these lesions could be susceptible to modification during pregnancy. The present case report describes a case of cystic transformation of a nodular neurofibroma, with progressive growth and mass effect in the(More)
Interhemispheric subdural hematoma (ISH) had been considered extremely rare until identification with imaging studies. Its natural history is still quite unknown in terms of potential origin and course. As a consequence of various controversies, there is still no clearly established treatment, particularly in regard to medical or surgical management. The(More)
Introduction The decompressive craniectomy is a surgical strategy widely used with specific criteria to control the refractory intracranial pressure (ICP). However, it is important to warn about the presence of a postcraniectomy syndrome and analyze the risk-benefit on a long term. Case Report A 72-year-old male patient diagnosed with a subarachnoid(More)
In this experiment, we evaluated the long-term effects of noise by assessing both astrocyte changes in medial prefrontal cortex (mPFC) and mPFC-related alternation/discrimination tasks. Twenty-one-day-old male rats were exposed during a period of 15 days to a standardized rats' audiogram-fitted adaptation of a human noisy environment. We measured serum(More)
INTRODUCTION A microsurgical anterior cervical approach with discectomy and fusion (MACDF) is one of the most widely used procedures for treating radicular disorders. This approach is highly successful; however, it is not free from complications. These can be associated with soft tissue injuries. AIM OF THE STUDY The recognition of the risks for these(More)
