1. Strong Stability Preserving Runge-Kutta Methods Applied to Water Hammer Problem
ABSTRACT The characteristic method of lines is the most used numerical method applied to the water hammer problem. It transforms a system of partial differential equations involving the independent variables time and space in two ordinary differential equations along the characteristics curves and then solve it numerically. This approach, although showing gr

2. A Surgical Technique to Preserve the Subvalvular Apparatus in Patients Undergoing Mitral Valve Replacement for Severe Ischemic Regurgitation
ABSTRACT Severe functional mitral valve regurgitation should be treated in patients undergoing myocardial revascularization. When replacement is considered the best therapeutic option, preservation of the mitral subvalvular apparatus is crucial, especially in the emergency setting, because of its primary role in preserving geometry and function of left and r

3. Corporoplasty: A simplified technique for clitoroplasty
ABSTRACT Introduction Clitoroplasty constitutes an important step in feminizing surgery for congenital adrenal hyperplasia (CAH) ( 1 ). In this video we present a technique that aims to preserve clitoral sensitivity and engorgement while minimizing the risk of neurovascular lesion. Materials and methods We present a video of a three-year-old girl with hi

4. Nerve-sparing robotic-assisted radical prostatectomy: how I do it after 15.000 cases
ABSTRACT Introduction: Over the years, since Binder and Kramer described the first Robotic-assisted Radical Prostatectomy (RARP) in 2000, different Nerve-sparing (NS) techniques have been proposed by several authors (1). However, even with the robotic surgery advantages, functional outcomes following RARP, especially erection recovery, still challenge surge

5. Adventitial Collagen Cross-Linking by Glutaraldehyde Reinforcing Human Saphenous Vein - Implication for Coronary Artery Bypass Grafting
ABSTRACT Introduction: A weak venous wall is one of the major reasons contributing to vein graft failure after coronary artery bypass grafting (CABG). We investigated whether adventitial collagen cross-linking by glutaraldehyde reinforces venous wall, preserving the endothelium of veins during high-pressure distention. Methods: Human saphenous veins (SVs)

6. The effect of preemptive airway pressure release ventilation on patients with high risk for acute respiratory distress syndrome: a randomized controlled trial
Abstract Background and objectives: The objective of this study was to investigate the use of early APRV mode as a lung protective strategy compared to conventional methods with regard to ARDS development. Methods: The study was designed as a randomized, non-blinded, single-center, superiority trial with two parallel groups and a primary endpoint of ARDS d

7. Complete corporeal preservation clitoroplasty: new insights into feminizing genitoplasty
ABSTRACT Introduction: 46,XX Congenital adrenal hyperplasia (CAH) remains the first cause of genital virilization and current surgical techniques aim to restore female aspect of genitalia while preserving dorsal neurovascular bundle but not at the expense of not preserving erectile tissue. We aim to report our experience with a new surgical technique for cl

8. High uterosacral ligament hysteropexy for the management of pelvic organ prolapse
ABSTRACT Objective: To demonstrate our transvaginal high uterosacral ligament (HUL) hysteropexy technique as an alternative mesh-free uterine-preserving pelvic organ prolapse (POP) repair approach and present our institutional outcomes. Concurrent hysterectomy with POP repair is controversial as uterine-preserving techniques may beneficially allow fertility

10. The importance of education
Abstract The present research is dedicated to analyzing the addition of sawdust biomass, which is a carbonaceous raw material that may be used in coal blends for the production of metallurgical coke, preserving the required quality, with lower cost. The quality of metallurgical coke may be determined by the efficiency of its chemical, physical and thermal fu

12. Early and Late-Term Follow-Up Results of Patients Diagnosed with Aortic Aneurysm or Aortic Dissection with Aortic Regurgitation Undergoing Aortic Valve Repair or Valve-Sparing Aortic Surgery
Abstract Introduction: Valve-reimplantation and remodelling techniques used in aortic reconstruction provide successful early, mid, and long-term results. We present our early and late-term experience with 110 patients with aortic regurgitation (AR) who underwent aortic valve repair (AVr) or valve-sparing aortic root surgeries (VSARS) due to aortic dissecti
