Cadherin Expression Profiles Define Glioblastoma Differentiation and Patient Prognosis.

Cadherins are cell-cell adhesion proteins which have been strongly implicated in cancer invasion, dissemination and metastasis capacity; thus, they are key players in the epithelial-to-mesenchymal transition (EMT) program. However, their role in glioblastoma (GBM), a primary central nervous system aggressive tumor, remains to be clarified. N-, E- and P-cadherin expression was analyzed on a large series of GBMs, characterized with clinical, imaging and neuropathological parameters, as well as with patients' survival data.

GET-UP Trial 1-year results: long-term impact of an early mobilization protocol on functional performance after surgery for chronic subdural hematoma.

Objective: Evidence on timing for mobilization after chronic subdural hematoma (cSDH) surgery is heterogeneous, and practices differ considerably among neurosurgical centers. The Impact of an Early Out-of-Bed Paradigm in Postoperative Outcomes of Chronic Subdural Hematomas: GET-UP Randomized Prospective Trial (GET-UP Trial) is a randomized clinical trial comparing a postoperative early mobilization protocol to bed rest. Previously reported results at clinical discharge and 1 month after surgery indicated a decreased risk of medical complications in the early mobilization group.

Impact of an early mobilization protocol on the reduction of medical complications after surgery for chronic subdural hematoma: the GET-UP Trial.

Objective: Timing of mobilization after chronic subdural hematoma (cSDH) surgery is highly heterogeneous among neurosurgical centers. Past studies have suggested that early mobilization may reduce medical complications without increasing recurrence, but evidence remains scarce. The purpose of this study was to compare an early mobilization protocol with a 48-hour bed rest practice, with a focus on the occurrence of medical complications.

Production of methylcellulose films functionalized with poly-ε-caprolactone nanocapsules entrapped β-carotene for food packaging application.

Nowadays, there is a worldwide demand in the production of innovative packaging that release active compounds to increase the shelf life of perishable food products. Therefore, this study produced methylcellulose films functionalized with poly-ε-caprolactone nanocapsules entrapped β-carotene. The nanoparticles were produced by the nanoprecipitation method, and 10, 30, and 50 % of nanoparticles colloidal solution was added in the methylcellulose filmogenic solution.

PD-L1 tumor expression is associated with poor prognosis and systemic immunosuppression in glioblastoma.

Purpose: Glioblastoma is the most common primary malignant brain tumor in the adult, whose grim prognosis largely relates to the absence of effective treatment targets. Given its success in other cancers, immunotherapy has been trialed in glioblastoma and failed to demonstrate the expected benefit. Importantly, these disappointing results highlight the importance of understanding the unique and transforming biology of glioblastoma and its microenvironment.

HIPTCN: Prospective Observational Study of Hypocoagulated Head Trauma Patients with Normal Admission Computed Tomography Scan.

Introduction: Our national protocol for traumatic brain injury dictates that hypocoagulated patients with mild trauma and initial tomography scan with no intracranial traumatic changes must be hospitalized for 24 hours and do a post-surveillance tomography scan. The main goal of this study was to evaluate the clinical relevance of these measures.

Material And Methods: A prospective observational study was undertaken in four hospitals.

Cadherin Expression and EMT: A Focus on Gliomas.

Cadherins are calcium-binding proteins with a pivotal role in cell adhesion and tissue homeostasis. The cadherin-dependent mechanisms of cell adhesion and migration are exploited by cancer cells, contributing to tumor invasiveness and dissemination. In particular, cadherin switch is a hallmark of epithelial to mesenchymal transition, a complex development process vastly described in the progression of most epithelial cancers.

T2-FLAIR mismatch sign: a roadmap of pearls and pitfalls.

T2-FLAIR mismatch sign has been advocated to be 100% specific for IDH-mutant 1p/19q non-codeleted gliomas (diffuse astrocytomas). However, false positives have been reported in recent works. Loose application of the criteria may lead to erroneous classification, especially by non-trained neuroradiologists.

Brain biopsy in suspected non-neoplastic neurological disease.

Unlabelled: Brain biopsy has a well-established role in the diagnosis of CNS neoplasia. Nevertheless, despite being essential for the diagnosis of some benign neurological diseases, little consensus exists regarding its indications for disease diagnosis and patient orientation. Our aim was to assess brain biopsy diagnostic yield in patients with neurological deterioration of unknown etiology, to identify the clinical characteristics associated with an increased likelihood of achieving a diagnostic biopsy as well as the characteristics linked to a particular diagnosis.

Antioxidant and antimicrobial methylcellulose films containing Lippia alba extract and silver nanoparticles.

Methylcellulose is a biopolymer, which can be used in the preparation of films for the production of biodegradable active packaging. In this work, the methylcellulose films containing biosynthesized silver nanoparticles (AgNPs) were developed using Lippia alba extract. The physico-chemical, antioxidant, and antimicrobial properties of the films were studied.

Supratentorial hemangioblastomas in von Hippel-Lindau wild-type patients - case series and literature review.

Background: Supratentorial hemangioblastoma is an uncommon lesion with few data available. Resemblance to other tumours represents a struggle concerning pre-operative diagnosis and management.

Objectives: The aim of this study was to review the current literature, integrating two new cases with uncommon features.

Expanded and Wild-type Ataxin-3 Modify the Redox Status of SH-SY5Y Cells Overexpressing α-Synuclein.

Neurodegenerative diseases are considered to be distinct clinical entities, although they share the formation of proteinaceous aggregates and several neuropathological mechanisms. Increasing evidence suggest a possible interaction between proteins that have been classically associated to distinct neurodegenerative diseases. Thus, common molecular and cellular pathways might explain similarities between disease phenotypes.

Characterization of antioxidant methylcellulose film incorporated with α-tocopherol nanocapsules.

Biodegradable and antioxidant films based on methylcellulose (MC) and α-tocopherol nanocapsule suspension (NCs) were developed. MC and NCs films were prepared by a casting method in three different proportions. The mechanical, wettability, colour, light transmission, antioxidant and release characteristics of the films were studied.
