This systematic review focused on the question, if and to what extent enamel matrix derivative (Emdogain) [EMD]) promotes the regeneration of bone. The influence of combinations with other biomaterials was additionally evaluated. Twenty histomorphometric studies were included in this systematic review. Main results of the reviewed articles were (i) guide tissue regeneration (GTR) of infrabony d...

Strain induced crystallization (SIC) of peroxide vulcanized natural rubber (NR)/ground tire (GTR) composites is studied by combining mechanical and microstructural characterization techniques. It found that the incorporation GTR into NR matrix leads to more effective reinforcement at large strains room temperature in NR/GTR as compared neat NR. attributed (i) presence particles acting reinforci...

Background Adjuvant radiotherapy (RT) after surgical resection of World Health Organization (WHO) grade II meningioma, also known as atypical meningioma (AM), is a topic of controversy. The purpose of this study is to compare overall survival (OS) with or without adjuvant RT after subtotal resection (STR) or gross total resection (GTR) in AM patients diagnosed according to the 2007 WHO classifi...

BACKGROUND The evidence for the efficacy of periodontal plastic surgery (PPS) in the treatment of recession defects has not yet been systematically evaluated. The objective of this review was to systematically review the efficacy of PPS in achieving root coverage in the treatment of localized gingival recession. The following surgical procedures have been considered in this review: guided tissu...

Surgery, radiation and chemotherapy are the standard of care for GBM patients, however, the impact of extent of resection (EOR) and radiotherapy (RT) on patient survival across age groups has not been established. Therefore, we present the current largest study on EOR and RT in GBM over the past three decades. Using the population based Surveillance, Epidemiology and End Results (SEER) registry...

In the future, the Global Technical Regulation (GTR) on pedestrian safety may be adopted as an Australian Design Rule. Eventually, this would require all new vehicles to meet a certain level of performance in pedestrian impact tests. This paper discusses the likely effects of such an ADR on vehicle design, and estimates the effect of the requirements on real world crash performance. This is don...

The general time-reversible (GTR) model (Tavaré, 1986) has been the workhorse of molecular phylogenetics for the last decade. GTR sits at the top of the ModelTest hierarchy of models (Posada & Crandall, 1998) and, usually with the addition of invariant sites and a gamma distribution of rates across sites, is currently by far the most commonly selected model for phylogenetic inference (see Table...

OBJECTIVE It remains unknown whether the extent of surgical resection affects survival or disease progression in patients with supratentorial low-grade gliomas. METHODS We conducted a retrospective cohort study (n = 170) between 1996 and 2007 at a single institution to determine whether increasing extent of surgical resection was associated with improved progression-free survival (PFS) and ov...
