Management of waste tires has become a leading environmental issue due to the global growth in number produced annually. This work is focused on exploring use Ground Tire Rubber (GTR) new class cost-effective, recycled composite materials. A Fused Filament Fabrication (FFF) desktop 3D printer used produce GTR-based material with up 50% wt. rubber filling. ABS as host matrix. Both microscopic an...

Intrabony periodontal defects present a particular treatment problem, especially in patients with generalized aggressive periodontitis (G-AgP). Regenerative procedures have been indicated for this clinical situation. The aim of this study was to compare treatment outcomes of intrabony periodontal defects with either anorganic bone matrix/cell binding peptide (ABM/P-15) or guided tissue regenera...

OBJECTIVE The aim of this study was to describe a single center's experience in the management of craniopharyngiomas in children over a 15-year period. METHODS The clinical records of pediatric patients treated for craniopharyngiomas between December 1995 and February 2011 were reviewed. Thirty-five pediatric patients diagnosed with craniopharyngioma were treated, and their medical records an...

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...
