Introduction: We wished to compare the survival benefit associated with gross total resection (GTR) in World Health Organization (WHO) grade II astrocytomas (A2) to those of grade III (A3) and grade IV (glioblastoma) astrocytomas. Methods: Using the Surveillance, Epidemiology, and End Results (SEER) Program (1999-2010) database, we identified 4,113 A2 patients. Surgical resection was defined as...

Heme and chlorophyll accumulate to high levels in legume root nodules and in photosynthetic tissues, respectively, and they are both derived from the universal tetrapyrrole precursor delta-aminolevulinic acid (ALA). The first committed step in ALA and tetrapyrrole synthesis is catalyzed by glutamyl-tRNA reductase (GTR) in plants. A soybean (Glycine max) root-nodule cDNA encoding GTR was isolate...

INTRODUCTION The purpose of this study was to determine factors and clinical situations that influence an endodontist's decision to use guided tissue regeneration (GTR) techniques during endodontic root-end surgery. METHODS An invitation to participate in a web-based survey was e-mailed to 3,750 members of the American Association of Endodontists. Data were collected from 1,129 participants, ...

Global Technical Regulation No. 9 on Pedestrian Protection (GTR 9) was adopted in 2008 to encourage vehicle front‐end designs that mitigate the consequences of vehicle‐to‐pedestrian collisions. The objective of the current study was to compare the types and sources of real‐world pedestrian injuries with the parts of the vehicle that would be affected by the tests prescri...

Surgical treatment of vestibular schwannoma is targeted at complete removal with preserved neurological function. Complete removal may cause significant deficits, whereas subtotal tumor removal is associated with a high recurrence rate. The present study assessed the risk of tumor recurrence and postoperative facial nerve function in relation to the extent of surgical resection by reviewing the...

Background/Objective The heart rate (HR) and metabolic (VO2) responses to treadmill running using the GlideTrak™ body weight support system have not been reported. The purpose of this study was to compare the submaximal and maximal HR and VO2 responses to normal-weight treadmill running (TMR) to treadmill running with body weight support provided by the GlideTrak™ (GTR). Methods Twenty partic...

AIM To report a well succeeded use of cyanoacrylate adhesive for fixating a resorbable membrane during a guided tissue regeneration procedure (GTR). BACKGROUND The immobilization of membranes in GTR is essential for establishing proper environment for cell differentiation and tissue regeneration. However, some membranes are very difficult to be kept in position by sutures and its fixation by ...

BACKGROUND 5-Aminolevulinic acid (5-ALA) fluorescence is a validated technique for resection of high grade gliomas (HGG); the aim of this study was to evaluate the surgical outcome and the intraoperative findings in a consecutive series of patients. METHODS Clinical and surgical data from patients affected by HGG who underwent surgery guided by 5-ALA fluorescence at our Department between Jun...

BACKGROUND Many clinical studies have demonstrated that guided tissue regeneration (GTR) is a successful treatment modality of periodontal reconstructive surgery and it has become an accepted procedure in most periodontal practices. RATIONALE The purpose of this structured review was to assess the efficacy of guided tissue regeneration (GTR) procedures in patients with periodontal osseous def...

The prognosis of patients with WHO grade III gliomas is highly dependent on their genomic status such as the isocitrate dehydrogenase (IDH) 1/2 mutation and1p/19q co-deletion. However, difficulties have been associated with determining which tumors have certain genomic profiles by preoperative radiographical modalities, and the role of surgical resection in achieving better outcomes remains unc...
