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...

The Gamow-Teller resonances (GTR) and isobaric analog states (IAS) of a sequence of even-even Sn target nuclei are calculated by using the framework of the relativistic Hartree-Bogoliubov model plus proton-neutron quasiparticle random-phase approximation. The calculation reproduces the experimental data on ground-state properties, as well as the excitation energies of the isovector excitations....

In this paper I argue that to understand minded agency – the capacity we typically find instantiated in instances of human behaviour that could sensibly be questioned by asking “What did you do?” – one needs to understand childhood, i.e. the trajectory of learning to act. I discuss two different types of trajectory, both of which seem to take place during childhood and both of which might be co...

One of the most important indications for guided tissue regeneration (GTR) treatment is class II furcation lesion. However, periodontal regeneration of this type of defect, although possible, is not considered totally predictable, especially in terms of complete bone fill. Many factors may account for variability in the response to regenerative therapy in class II furcation. The purpose of this...

As phylogenetic datasets have increased in size, site-heterogeneous substitution models such as CAT-F81 and CAT-GTR have been advocated in favor of other models because they purportedly suppress long-branch attraction (LBA). These models are two of the most commonly used models in phylogenomics, and they have been applied to a variety of taxa, ranging from Drosophila to land plants. However, ma...

A retrospective study of 81 patients with low-grade astrocytoma (LGA) comparing the efficacy of aggressive versus less aggressive surgery in eloquent and non-eloquent brain areas was conducted. Extent of surgical resection was analyzed to assess overall survival (OS) and progression- free survival (PFS). Degree of tumor resection was classified as gross total resection (GTR), subtotal resection...

PURPOSE The aim of this study was a comparative analyses of clinical treatment efficiency of periodontium recessions after the application of double pedicle bilateral flap (DPBF), coronally repositioned flap in combination with connective tissue graft (CRF-CTG), coronally advanced flap in combination with guided tissue regeneration using collagen membranes (GTR-CM). MATERIAL AND METHODS Resea...

We reviewed the literature on the efficacy of enamel matrix derivative (EMD) in comparison with open flap debridement, guided tissue regeneration (GTR), and bone grafting for the treatment of intrabony defects. We searched four major electronic databases for randomized controlled trials (RCTs) with at least one year of follow-up. Several journals were handsearched with no language restrictions....
