Among the possible complications of hemodialysis polytetrafluoroethylene (PTFE) graft creation, perigraft seromas are rare, but sometimes troublesome. Debridement with drainage is usually the method of treatment. However, recurrence is not unusual. Herein we describe 2 cases of recurrent perigraft seroma treated by a simple but effective surgical method: excision of the pseudocapsule and revisi...

BACKGROUND AND OBJECTIVE Peritoneal dialysis (PD) remains the generally accepted method for management of renal failure in chronic and acute renal failure. Despite the rapidly increasing use of continuous ambulatory peritoneal dialysis (CAPD) since its introduction, controversy persists as to the efficacy and exact role of the modality in the treatment of end stage renal failure. The aim of thi...

Random Early Detection (RED) is one of the most commonly used Active Queue Management (AQM) algorithms that is recommended by IETF for deployment in the network. Although RED provides low average queuing delay and high throughput at the same time, but effectiveness of RED is highly sensitive to the RED parameters setting. As network condition varies largely, setting RED's parameters with fixed ...

Using lattice theory on specialK3 surfaces, calculations on moduli stacks of pointed curves and Voisin’s proof of Green’s Conjecture on syzygies of canonical curves, we prove the Prym-Green Conjecture on the naturality of the resolution of a general Prym-canonical curve of odd genus, as well as (many cases of) the Green-Lazarsfeld Secant Conjecture on syzygies of non-special line bundles on gen...

The study was aimed at demonstrating the effectiveness of peritoneal dialysis in the treatment of cats with severe renal insufficiency. Continued peritoneal dialysis was performed on three cats of mixed breeds, with the symptoms of renal failure. In the course of dialysis level of urea and creatinine, content of glucose and protein, level of Mg, P, Ca, and activity of liver enzymes (AST, ALT, A...

BACKGROUND An on-line monitoring system for dialysis dose calculations could make it possible to provide an adequate dialysis dose that is consistently given to haemodialysis (HD) patients. The aim of this study was to compare dialysis dose (Kt/V) using four different methods and their sensitiveness to a reduction in clearance. METHODS Six patients were monitored on-line with ultraviolet (UV)...

BACKGROUND Several major ESRD-related regulatory and reimbursement changes were introduced in the United States in 2011. In several large, national datasets, these changes have been associated with decreases in erythropoiesis stimulating agent (ESA) utilization and hemoglobin concentrations in the ESRD population, as well as an increase in the use of red blood cell (RBC) transfusions in this po...

That colour polymorphism may protect prey populations from predation is an old but rarely tested hypothesis. We examine whether colour polymorphic populations of prey exposed to avian predators in an ecologically valid visual context were exposed to increased extinction risk compared with monomorphic populations. We made 2976 artificial pastry prey, resembling Lepidoptera larvae, in four differ...

Hemodialysis influences the transport of water through the erythrocytic membrane, and induces morphologic and functional modifications. Recently water channels, called aquaporins (AQP), have been identified on the membrane of red blood cells. The aim of the present study was, therefore, to evaluate any relationships between volumetric changes in erythrocytes (MCV), plasma osmolarity and membran...

Continuous ambulatory peritoneal dialysis is a new and increasingly popular method of routine dialysis, but its effect on renal transplantation is uncertain. A non-randomised comparison was made of the outcome of grafting in patients who had been treated before transplantation with continuous ambulatory peritoneal dialysis with that in patients treated with haemodialysis. During the five years,...
