BACKGROUND Ependymomas are rare tumors of the central nervous system whose management is controversial. This population-based study of adults and children with ependymoma aims to (1) identify clinical and treatment-related factors that impact survival and (2) determine if postoperative radiotherapy (RT) can improve survival of patients with subtotal resection (STR) to levels similar to patients...

Background The treatment of furcation area defects remained as a challenging issue in periodontal treatments. Regeneration treatment of furcation defects is the most discussed periodontal treatment. Although not completely hopeless in prognosis, the presence of the furcation involvement significantly increases the chance of tooth loss. The current research was conductedeto compare theeadditive ...

OBJECT The goal of this study was to evaluate the therapeutic impact of the resection of metastatic brain tumor cells infiltrating adjacent brain parenchyma. METHODS Between July 2001 and February 2007, 94 patients (67 males and 27 females, with a mean age of 55.0 +/-12.0 years) underwent resection of a single brain metastasis, followed by systemic chemotherapy with or without radiotherapy. I...

The Genetic Testing Registry (GTR) is a voluntary registry of genetic tests initiated and created by the National Institutes of Health (NIH) (Field et al, 2011). Given the proliferation of tests for many genetic conditions, the NIH recognized that a centralized public database for information about these tests was needed. NIH launched the GTR project ‘‘to advance public health and research in t...

1 The motivations for introducing a “new” mathematical tool within the general theory of relativity (A. Einstein’s work GTR) have been intensively exposed in a first paper [vixra.org; 1311.0004]. This “companion” paper develops an argumentation allowing the intervening of the same tool in a pure 4D space. So far we know, it is one of the first theoretical works connecting the GTR and the Quantu...

OBJECT With recent advances in the adjuvant treatment of malignant brain astrocytomas, it is increasingly debated whether extent of resection affects survival. In this study, the authors investigate this issue after primary and revision resection of these lesions. METHODS The authors retrospectively reviewed the cases of 1215 patients who underwent surgery for malignant brain astrocytomas (Wo...

Goal number 12 of the UN 2030 Agenda for Sustainable Development is sustainable consumption and productions. Recycling has a central role in assuring to meet target 2030. Only EU, annual total waste spent tire 3.7 million tons [1]; it impelling find way recycle this material. This article investigates feasibility use ground rubber (GTR) as feedstock injection molding by blending with polypropyl...

Polymer membranes have been widely used in guided tissue regeneration (GTR) and guided bone regeneration (GBR). In this review, various commercially available membranes are described. Much attention is paid to the recent development of biodegradable polymers applied in GTR and GBR, and the important issues of biodegradable polymeric membranes, including their classification, latest experimental...
