Determination of indium by adsorptive stripping voltammetry at the bismuth film electrode using combined electrode system facilitating medium exchange.

A novel method of determining indium has been described in this article which uses adsorptive stripping voltammetry (AdSV) and 4-(2-pyridylazo)-resorcinol (PAR) as a chelating agent or as the preconcentration agent. The measurements were performed using square-wave voltammetry by using a combined electrode system, which allows for preconcentration and stripping without opening the circuit. Ex situ plated bismuth film electrode (BiFE) was used as the working electrode.

Voltammetric studies of glutathione transfer across arrays of liquid-liquid microinterfaces for sensing applications.

The simple and facilitated transfer of tripeptide glutathione across the water/2-nitrophenyl octhyl ether interface was studied via cyclic voltammetry at interface between two immiscible electrolyte solutions (ITIES). The micro-perforated membrane prepared with a laser with a femtosecond pulse was used for mechanical stabilization of the interface. The method of cyclic voltammetry was used to study the passive and facilitated interfacial transfer of glutathione and its complex with the crown ether dibenzo-18-crown-6 (DB18C6).

Autonomous dysregulation of orthostatic disorders in young individuals engaged into manual work.

The authors analyzed changes of statistic, spectral and non-linear parameters of cardiac rhythm variability in response to active orthostasis test in young individuals engaged into manual work, and the results are compared with hemodynamic parameters. Evidence is that the patients with neurogenous fainting present sympathetic vasomotory regulation disorders even in young age; before clinical manifestation as orthostatic hypotension. In comparison with common tilt-test, spectral analysis of cardiac rhythm variability in active orthostatic test can be more useful to reveal early disorders of autonomous regulation.

Anesthesia management of a 20-month-old patient with giant unilateral wilms tumor.

Wilms tumour (WT) (or nephroblastoma) is one of the most common malignant kidney tumors in children. On subsequent stages clinically it is often characterized by abdominal hypertension syndrome, which, in turn, leads to development of respiratory insufficiency. Other symptoms comprise renal deficiency, hypertension, and abnormalities of hemostasis and hemogram.

[The characteristics of the clinical picture and treatment of patients with acute kidney failure in obstetrical pathology].

The examination of 45 patients with acute renal failure (ARF) caused by obstetric problems identified 3 types of its clinical course: 1) "pure" ARF; 2) ARF in the presence of sepsis, and 3) ARF in the presence of exogenous intoxication. Types 2 and 3 were more severe and showed higher mortality rates. The average number of hemodialysis sessions per patient was 2.
