Abstract Introduction: Recent evidence suggests that radical cystectomy may be underutilized in elderly patients, despite literature supporting acceptable morbidity/mortality in this population. However, there is a paucity of literature reporting complications in a standardized manner. Therefore, we evaluated the morbidity and mortality of octogenarians treated with radical cystectomy using the modified Clavien complication reporting system.
Materials and methods: We retrospectively reviewed 443 consecutive patients undergoing radical cystectomy at our institution between January 2000 and April 2010. Patients who underwent cystectomy for benign conditions were excluded, leaving 359 for analysis. Baseline demographic and perioperative data were reviewed and all… More >

Abstract Radical prostatectomy remains the standard treatment for long term cure of clinically localized prostate cancer, offering excellent oncologic outcomes, with cancer-specific survival approaching 95% at 15 years after surgery. The introduction of the “da Vinci Robotic Surgical System” (Intuitive Surgical, Sunnyvale, CA, USA) has been another important step toward a minimally invasive approach to radical prostatectomy. Technologic peculiarities, such as three-dimensional vision, wristed instrumentation with seven degrees of freedom of motion, lack of tremor, a 10x-magnifcation and a comfortable seated position for the surgeon has added value to the surgeon and patient. In this frst More >

Abstract Introduction: There are many concerns expressed by urologists performing robotic assisted laparoscopic prostatectomy (RALP) regarding management of the dorsal vein complex (DVC). We sought to examine the influence of delayed DVC ligation versus standard DVC ligation on the apical surgical margin status and other key surgical parameters following RALP.
Materials and methods: The Columbia University Urologic Oncology Database was retrospectively reviewed to identify patients who underwent RALP between 2008-2011. Operative records were analyzed to determine whether the DVC was ligated in the 'standard' or 'delayed' manner. The standard group had the DVC ligated prior to the apical… More >

Abstract The introduction of the “da Vinci Robotic Surgical System” (Intuitive Surgical, Sunnyvale, CA, USA) has been an important step toward a minimally invasive approach to radical prostatectomy. Technological peculiarities, such as three-dimensional vision, wristed instrumentation with seven degrees of freedom of motion, lack of tremor, 10x magnification, and a comfortable seated position for the surgeon, have added value to the procedure for both the surgeon and the patient. In this article, we describe the 9-step surgical technique for robot-assisted radical prostatectomy (RARP) that is currently used in our institution (University of Montreal Hospital Center (CHUM) More >

Abstract Introduction: Inflammation plays a key role in the development of benign prostatic hyperplasia. Prostaglandin E2 (PGE2) is an important inflammation factor found in enlarged prostatic tissue that can be the main cause of inflammatory pain. The aim of this study was to investigate whether epidural anesthesia can block the negative effects of prostaglandin mediators during prostate surgery.
Materials and methods: The study included 60 patients who underwent open prostatectomy. All patients were randomly allocated to one of two study groups. The first group received general anesthesia and the second group a combination of general and epidural anesthesia.… More >

Abstract The papain catalyzed enzymatic synthesis of amido amines catalyzed from aromatic diamines and N-carbobenzyloxy (Z) protected amino acids (Gly, L-Leu, L-Phe) is described. The amides precipitate (yield 19–47 % depending on the amino acid used) from the reaction mixture after one amide bond is formed thus preventing the formation of diamides in all cases. Papain retains its activity in buffers with a higher pH (9 and 12) observable by the amide bond formation between 1,3-phenylene diamine and Z-L-Gly and Z-L-Phe. Aliphatic diamines (1,4-butanediamine and 1,6-hexanediamine) were used as well but amide formation could not be More >

Abstract Chromium (Cr) is a highly toxic non-essential metal for microorganisms and plants; due to its frequent industrial use, it has become a pollutant for different agroecosystems. Arbuscular mycorrhizal fungi (AMF) are associated with most angiosperms and provide them with beneficial effects on the absorption of some nutrients. Moreover, it has been reported that in some cases the AMF can confer greater tolerance to plants in the presence of heavy metals. The tomato (Solanum lycorpersicum) is an important crop in Mexico. In most cases, it grows under applied irrigation water from reservoirs which include domestic and industrial… More >

Abstract Corn has not only a high growth potential and a great capacity of biological response to suitable crop management but also may contribute to a better match of crops with environmental offer in Argentina. Nitrogen (N) fertilization must make provision for eventual N losses, and fertilization strategies must be designed so as to minimize their global incidence. The different quick-release N sources show similar efficiencies when they are incorporated, but in surface applications, sources that contain little or no amidic N have a better performance than urea (U). The objective of this paper was to… More >

Abstract Nanotechnology is currently an important worldwide study field because it provides control on matter at a nanometric scale. In food and agricultural fields, the applications of this technology are in early stages. Onion is one of the main vegetables grown in the world. Onion is a low calorie food which contains a large amount of flavonoids. In this work, silver nitrate application in onion was evaluated. An onion crop was developed at the University Antonio Narro in Saltillo, Mexico. Two methods of silver nitrate application were used (a nutritive solution: 0, 20, 40 and 80… More >
