OBJECTIVES: To report the long-term outcome of ileal ureteric replacement (IUR) in complex reconstruction of the urinary tract. PATIENTS AND METHODS: From 1991 to 2016, IUR was performed in 157 patients with structural or functional ureteric loss. In 52 patients, bilateral IUR became necessary. Implantation sites where either the native urinary bladder (n=79) or intestinal reservoirs (n=78). In the latter group, the technique was used at the time of primary urinary diversion (n=34), in a secondary approach (n=29) and in undiversion or conversion procedures (n=15)...

OBJECTIVES: In renal transplant recipients, the risk of developing bladder cancer and rate of diagnosis of advanced staged bladder cancer are generally higher than the general population. Also, it is more challenging to treat renal transplant recipients than the regular patient population. We aimed to evaluate the efficacy and safety of radical cystectomy (RC) and urinary diversion with ileal conduit in renal transplant recipients. METHODS: We identified 2 patients with prior history of renal transplantation who underwent RC and ileal conduit urinary diversion for bladder cancer...

Standard aortic valve replacement for aortic regurgitation caused by Behçet's disease is frequently complicated by postoperative recurrent prosthetic valve detachment. To prevent this, we have developed a modified Bentall procedure, in which the valved conduit is proximally attached to the left ventricular outflow tract instead of to the fragile annulus, based on the fact that the left ventricular outflow tract myocardium is rarely involved in Behçet's disease. This modified Bentall procedure was performed in 5 Behçet's disease patients with prosthetic valve detachment after primary aortic valve replacement, and satisfactory results were achieved...

This article proposes to move forward analytical work on the human aspect of socio-economic development, by featuring how personal decisions about physical appearance in effect negotiate socio-ethnic positions and desired economic aims that arise from new technologies of living. By envisioning how the body can serve as a conduit of consciousness-making, tattoos work as one cultural practice that produces an interplay between traditional precedents and contemporary trends and permits reflecting on how the categorizations of rural/urban can behave as a dialectical medium for internal anxieties and debates regarding social transformation...

Endothelin-1 (ET-1) is essential for mammalian development and life, but it has also been implicated in increased cardiovascular risk under pathophysiological conditions. The aim of this study was to determine the impact of endothelial overexpression of the prepro-endothelin-1 gene on endothelium-dependent and endothelium-independent responses in the conduit and renal arteries of lean and obese mice. Obesity was induced by high-fat-diet (HFD) consumption in mice with Tie-1 promoter-driven, endothelium-specific overexpression of the prepro-endothelin-1 gene (TET(het)) and in wild-type (WT) littermates on a C57BL/6N background...

Type-1 secretion systems (T1SSs) represent a widespread mode of protein secretion across the cell envelope in Gram-negative bacteria. The T1SS is composed of an inner-membrane ABC transporter, a periplasmic membrane-fusion protein, and an outer-membrane porin. These three components assemble into a complex spanning both membranes and providing a conduit for the translocation of unfolded polypeptides. We show that ATP hydrolysis and assembly of the entire T1SS complex is necessary for protein secretion. Furthermore, we present a 3...

Research has demonstrated that military service members are at elevated risk for a range of psychiatric problems, and mental health services use is a conduit to symptom reduction and remission. Nonetheless, there is a notable underutilization of mental health services in this population. This systematic review aimed to identify and critically examine: (1) rates of service use; (2) barriers and facilitators to care; and (3) programs and interventions designed to enhance willingness to seek care and increase help-seeking behaviors among current military personnel (e...

The development of an automated kinetic-catalytic spectrophotometric method for cobalt determination is presented. The method is based on the catalytic effect of Co in the oxidation of hydroxybenzoic acid by H2O2 in basic media. The method has been automated using a multisyringe flow injection system coupled to a monolithic flow conduit called chip (chip-MSFIA). All reagents and sample are simultaneously propelled into the chip to achieve an efficient mixing. The reaction product is monitored at 482nm. The reaction takes place very fast at room temperature, thus the fixed-time method is applied to quantify Co concentration in samples...

Percutaneous pulmonary valve intervention (PPVI) is a less invasive and less costly approach to pulmonary valve replacement compared with the surgical alternative. Potential complications of PPVI include coronary compression and pulmonary arterial injury/rupture. The purpose of this study was to characterize the morphological risk factors for PPVI complication with cardiac MRI and cardiac CTA. A retrospective review of 88 PPVI procedures was performed. 44 patients had preprocedural cardiac MRIs or CTAs available for review...

Impact of the unphysical tangential advective-diffusion constraint of the bounce-back (BB) reflection on the impermeable solid surface is examined for the first four moments of concentration. Despite the number of recent improvements for the Neumann condition in the lattice Boltzmann method-advection-diffusion equation, the BB rule remains the only known local mass-conserving no-flux condition suitable for staircase porous geometry. We examine the closure relation of the BB rule in straight channel and cylindrical capillary analytically, and show that it excites the Knudsen-type boundary layers in the nonequilibrium solution for full-weight equilibrium stencil...

Irina Ginzburg
The effect of the heterogeneity in the soil structure or the nonuniformity of the velocity field on the modeled resident time distribution (RTD) and breakthrough curves is quantified by their moments. While the first moment provides the effective velocity, the second moment is related to the longitudinal dispersion coefficient (k_{T}) in the developed Taylor regime; the third and fourth moments are characterized by their normalized values skewness (Sk) and kurtosis (Ku), respectively. The purpose of this investigation is to examine the role of the truncation corrections of the numerical scheme in k_{T}, Sk, and Ku because of their interference with the second moment, in the form of the numerical dispersion, and in the higher-order moments, by their definition...
