BACKGROUND: Open radical cystectomy (ORC) has proven to be an important component in the treatment of high-risk bladder cancer (BCa). ORC surgical morbidity remains high; therefore, minimally invasive surgical techniques have been introduced in an attempt to improve patient outcomes. OBJECTIVE: To compare cancer outcomes in BCa patients managed with ORC or robotic-assisted radical cystectomy (RARC). DESIGN, SETTING, AND PARTICIPANTS: A prospective, randomized trial was completed between 2010 and 2013...

BACKGROUND: Open radical cystectomy (ORC) is regarded the standard treatment for muscle-invasive bladder cancer, but robot-assisted radical cystectomy (RARC) is increasingly used in practice. However, it is unclear whether RARC provides value for money. OBJECTIVE: To identify the main evidence gaps and main drivers of cost-effectiveness, comparing RARC to ORC. DESIGN, SETTING, AND PARTICIPANTS: A decision analytical model was developed to study the 30d and 90d postoperative complications with RARC versus ORC and their related cost in bladder cancer patients...

We found that the Su(Hw) insulator protein binds to all known Drosophila amplicons in follicular cells (DAFCs). Su(Hw) binding is required for ORC replication complex positioning on part of DAFCs during early oogenesis. Our data allow us to expand the current view on the role of the Su(Hw) protein in Drosophila oogenesis as a transcription repressor. We assume that Su(Hw) is involved in the coordination of transcription and replication processes during oogenesis in Drosophila.

BACKGROUND: Birt-Hogg-Dubé syndrome (BHDS) is a recently recognized inherited multiple cystic lung disease causing recurrent pneumothoraces. Similarly to the lesions in patients with lymphangioleiomyomatosis (LAM), the pulmonary cysts are innumerable and widely dispersed and cannot all be removed. We recently described a total pleural covering (TPC) that covers the entire visceral pleura with oxidized regenerated cellulose (ORC) mesh. TPC successfully prevented the recurrence of pneumothorax in LAM patients...

Introduction: Urothelial cell carcinoma is the most common neoplasm of the genito-urinary tract, which, in advanced stages, is treated with radical cystectomy with pelvic lymphadenectomy. It can be performed by an open or minimally invasive approach (laparoscopic and robot-assisted radical cystectomy).Large meta-analyses showed a significantly lower complication rate in the RARC (robot-assisted radical cystectomy) group compared to ORC (open radical cystectomy) in thirty and ninety days after surgery, with similar oncological and functional outcomes...

Introduction: Open radical cystectomy (ORC) is the most common surgical approach for invasive carcinoma of the urinary bladder, but robot-assisted radical cystectomy (RARC) has recently gained popularity. There is limited data from the Indian subcontinent on RARC. The aim of this study was to assess the perioperative, pathological, and oncological outcomes of RARC and follow-up in our initial 63 cases. Materials and Methods: A retrospective analysis of prospectively maintained data of 63 RARC procedures performed in our tertiary care institute from July 2006 to January 2016 was done...

Robot-assistance is being increasingly used for radical cystectomy (RC). Fifteen years of surgical evolution might be considered a short period for a radical procedure to be established as the treatment of choice, but robot assisted radical cystectomy (RARC) is showing promising results when compared with the current gold standard, open RC (ORC). In this review, we describe the current status of RARC and continue the discussion on the on-going RARC versus ORC debate.

OBJECTIVE: Laparoscopic cholecystectomy is the first-choice treatment for symptomatic cholelithiasis. Though generally safe, this procedure is not without complications, with bleeding the most frequent cause of conversion to open cholecystectomy. Oxidized regenerated cellulose (ORC) added to conventional hemostatic strategies, is widely used to control bleeding during surgery despite limited evidence supporting its use. This retrospective study analyzed patients undergoing laparoscopic cholecystectomy in an Italian center over a 16-month period, between October 2014 and February 2016, who experienced uncontrollable bleeding despite the use of conventional hemostatic strategies, requiring the addition of ORC gauze (Emosist® )...

The economic and environmental impact of several waste-to-energy (WtE) schemes to produce electricity from municipal solid waste (MSW) refuse is evaluated and compared with landfill disposal. Both incineration and gasification alternatives are considered. The gasification option includes three different configurations: (1) a fluidized bed gasifier (FBG) with internal combustion engine (ICE), (2) a FBG with organic Rankine cycle (ORC) and (3) a grate gasifier with steam Rankine cycle (SRC). The study is primarily applied to regions where the management system is based on Mechanical Biological Treatment (MBT) plants, generating a large share of refuse (>70%), which is currently landfilled...

The processing advantage of Subject-gapped relative clause (SRC) versus Object-gapped relative clause (ORC) has been advocated by competing processing accounts. Using a self-paced listening paradigm, this study investigates what Chinese RC online processing asymmetry looks like under concurrent memory load manipulation. Both On-line listening times and Post-online measures of Chinese SRCs and ORCs are estimated and compared. The on-line results show that ORCs and SRCs demonstrate no differential processing patterns under the interfering conditions...

Malaria parasites use an extensive secretory pathway to traffic a number of proteins within itself and beyond. In higher eukaryotes, Endoplasmic Reticulum (ER) membrane bound transcription factors such as SREBP are reported to get processed en route and migrate to nucleus under the influence of specific cues. However, a protein constitutively trafficked to the nucleus via classical secretory pathway has not been reported. Herein, we report the presence of a novel trafficking pathway in an apicomplexan, Plasmodium falciparum where a homologue of an Origin Recognition Complex 2 (Orc2) goes to the nucleus following its association with the ER...

Introduction: Understanding how the nuclear genome of kinetoplastid parasites is replicated received experimental stimulus from sequencing of the Leishmania major, Trypanosoma brucei and Trypanosoma cruzi genomes around 10 years ago. Gene annotations suggested key players in DNA replication initiation could not be found in these organisms, despite considerable conservation amongst characterised eukaryotes. Initial studies that indicated trypanosomatids might possess an archaeal-like Origin Recognition Complex (ORC), composed of only a single factor termed ORC1/CDC6, have been supplanted by the more recent identification of an ORC in T...

Introduction: Open radical cystectomy (ORC) has been the standard treatment for muscle-invasive bladder cancer, but this is associated with significant morbidity and mortality. Robot-assisted radical cystectomy (RARC) has been proposed as minimally invasive alternative with improved morbidity and acceptable oncological outcomes, but a large series featuring RARC and their comparison with ORC is still lacking in India despite more than a decade of its inception. We have conducted this study with an objective to see the feasibility of RARC in the Indian context and compare it with contemporary standard...

Background: The field of postgraduate medical education (PGME) is continuously evolving as a result of social demands and advancing educational insights. Change experts contend that organizational readiness for change (ORC) is a critical precursor for successful implementation of change initiatives. However, in PGME, assessing change readiness is rarely considered while it could be of great value for managing educational change such as curriculum change. Therefore, in a previous Delphi study the authors developed an instrument for assessing ORC in PGME: Specialty Training's Organizational Readiness for curriculum Change (STORC)...
