Assessing the Applicability of the GTR Nucleotide Substitution Model through Simulations [PDF]
Evolutionary Bioinformatics, 2006 The General Time Reversible (GTR) model of nucleotide substitution is at the core of many distance-based and character-based phylogeny inference methods. The procedure described by Waddell and Steel (1997), for estimating distances and instantaneous substitution rate matrices, R, under the GTR model, is known to be inapplicable under some conditions ...

Gelatin-hydroxyapatite nano-fibers as promising scaffolds for guided tissue regeneration (GTR): Preparation, assessment of the physicochemical properties and the effect on mesenchymal stem cells [PDF]
Journal of Advanced Periodontology and Implant Dentistry, 2020 Background. Periodontitis can lead to progressive destruction of periodontal tissues supporting the tooth. Developing biomaterials for tissue engineering has noticeably improved the existing treatment options.

Recent advances in GTR scaffolds
Bioinformation, 2022 Periodontitis is a serious chronic inflammatory condition that can cause periodontal tissue deterioration and, eventually, tooth loss. Periodontal regenerative therapy using membranes and bone grafting materials, as well as flap debridement and/or flap curettage, have all been used with varying degrees of clinical effectiveness.

Reuse of ground tire rubber (GTR) as a filler of TPE matrix* [PDF]
MATEC Web of Conferences, 2021 Used car tires are the type of waste that does not decompose naturally and is not recyclable in molten state. Despite many initiatives to reuse these materials on a global scale, a large part of used tires are still landfilled.

Resection and Regeneration – A Novel Approach in Treating a Perio-endo Lesion [PDF]
Journal of Clinical and Diagnostic Research, 2015 The pulp and the periodontium are invariably anatomically and functionally related to each other. Lesions involving both the periodontium and the pulp complicate diagnosis, treatment planning and prognosis. An emerging approach to periodontal therapy is

THE GTR-MODEL: A UNIVERSAL FRAMEWORK FOR QUANTUM-LIKE MEASUREMENTS [PDF]
Probing the Meaning of Quantum Mechanics, 2016 We present a very general geometrico-dynamical description of physical or more abstract entities, called the 'general tension-reduction' (GTR) model, where not only states, but also measurement-interactions can be represented, and the associated outcome probabilities calculated.
