Objectives: We report our experience with subureteral submucosal injection therapy for vesicoureteral reflux and determine the safety and efficacy in patients treated with dextranomer/ hyaluronic acid co-polymer. Background: Vesicoureteral reflux affects 1% of children and increases the chances of urinary tract infection, pyelonephritis, hypertension and chronic renal insufficiency. The aim of ...

OBJECTIVES Primarily, to determine the association between the clinical severity of primary varicose veins and different reflux patterns in an anatomic and haemodynamic clinical study using duplex ultrasonography (DU). Secondly, to analyse the association of clinical severity with other aspects, such as risk factors for chronic venous insufficiency (CVI) and other concurrent diseases. METHOD ...

AIM The aim of the study was to provide an updated position statement from the ESPGHAN European Pediatric Impedance Working Group on different technical aspects such as indications, methodology, and interpretation of multichannel intraluminal impedance-pH monitoring (MII-pH). METHODS Evidence was used where available, but the article is based mainly on expert opinion and consensus. RESULTS ...

introduction: the purpose of this study was to evaluate the sealing ability of 3 obturation techniques in oval-shaped canals by bacterial leakage assessment. methods: sixty mandibular incisors with oval canals were selected after providing buccolingual and mesiodistal radiographs. the teeth were sectioned at a 10 mm distance from the apex. after instrumentation, the teeth were divided into 3 gr...

The main objective of this article aims to enhance a single stage absorption refrigeration machine, using the ammonia-water pair as working fluid, and from improvement its exergetic performances by means vapor rectification system. rectifier makes it possible emit enriched in pure fluid (ammonia) with high flow rate; one is thus transformed into condensate after condensation; also allows evacua...

We present a short review of how the effective action formalism, well known in relativistic quantum field theory, can be used to discuss Bose-Einstein condensation of non-relativistic gases. This method lends itself very naturally to an interpretation of Bose-Einstein condensation in terms of symmetry breaking. It also allows for the definition of a very elegant regularization technique involvi...

Condensation energy can be thought as the difference in ground state energy between the normal state and the superconducting state in a superconductor. In a way to understand and prove theory for superconducting transition, an accurate measurement of the condensation energy is needed [1]. The most common method for determination of condensation energy is by measuring the thermodynamical critica...

We report the development of a new method for producing mitotic extracts from tissue culture cells. These extracts reproducibly promote the condensation of chromatin in vitro when incubated with purified interphase nuclei. This condensation reaction is not species specific, since nuclei from chicken, human, and hamster cell lines all undergo chromatin condensation upon incubation with the extra...

The self-condensation of alkynals was for the first time implemented under mild organocatalytic conditions and was successfully linked with a domino organocatalytic inverse-electron-demand oxa-Diels-Alder reaction, which led to the development of a facile one-pot method to produce a wide variety of polysubstituted chiral 3,4-dihydropyrans with good to high yields and diastereoselectivities and ...
