background and aims. a combination of guided tissue regeneration (gtr), bovine porous bone mineral (bpbm), and platelet rich plasma has been already applied for the regeneration of intrabony defects. the aim of this study was to determine the role of plasma rich in growth factor (prgf) alone in the periodontal regeneration of intrabony defects in humans as compared with bpbm/gtr technique. mate...

Inference of evolutionary trees and rates from biological sequences is commonly performed using models of character change that incorporate rate variation across sites. Though an incorrect proof of the identifiability of the GTR+Γ+I model has been published, very little has been rigorously established concerning the identifiability of the models currently in common use in data analysis. Here we...

The coupling constants GKNΛ and GKNΣ are obtained from the GoldbergerTreiman relation in the strange channel with chiral symmetry breaking taken into account. The results, GKNΛ = −12.3±1.2 and GKNΣ = 5.5±.5 come close to the SU(3) values. The Kaon-Baryon coupling constants GKNΛ and GKNΣ are essential ingredients in the study of Kaon-Nucleon scattering or of the strangeness content of the nucleo...

Glioblastoma (GBM) is an aggressive, common brain cancer known to disrupt redox biology, affecting behavior and DNA integrity. Past research remains inconclusive. To further understand this, investigation was conducted on physical training’s effects behavior, balance, genomic stability in GBMA models. Forty-seven male C57BL/6J mice, 60 days old, were divided into GBM sham groups (n = 15, n 10, ...

OBJECTIVE Observe whether a microsurgical gross total removal (GTR) of a spinal nerve sheath tumors (SNSTs) is safe and decreases the tumor recurrence. METHOD We identify 30 patients with 44 SNSTs. RESULTS We operated upon 15 males and 15 females patients; mean age 40 years. GTR was achieved in 29 (96.6%) instances. Surgical mortality was 3.3% and the recurrence rate was 3.3%. The median fo...

When a guided tissue regeneration (GTR) membrane is placed in an interproximal area, adjustment of the membrane is difficult because of the complex anatomy of the root surface and presence of bone defects, thus prolonging the surgery. This report describes the clinical application of cone beam computed tomography (CT) images to aid insertion of a barrier membrane in the treatment of interproxim...

The world of dentistry knows the benefits and results guided bone regeneration. One most successful techniques introduced a decade ago utilizes, as barrier membrane, sheet made collagenated xenograft called lamina. Indications applications with different surgical have been well described by several authors. This technique not only presents very low degree complications, but also has some added ...
