Congestive heart failure represents a severe health condition with unfavourable long-term prognosis despite all the progress in pharmacological therapy of heart failure. Another therapeutic option is represented by mechanical cardiac support devices. Ventricular assist devices (VAD) constitute largest subgroup of these devices. Patients supported with VAD(More)
Gamma-glutamyl transpeptidase (GGT) activity is heterogeneously distributed between the lumbosacral chick spinal cord and the adjacent glycogen body during late embryonic and early posthatch development and displays hormonal sensitivity. As GGT activity may reflect the cellular transport of some amino acids, the transiently high activity of this enzyme in(More)
OBJECTIVES The aim was to investigate (1) whether collateral bronchopulmonary circulation developing due to chronic pulmonary embolism could prevent the evolution of pulmonary infarction after induction of pulmonary venous outflow impairment; and (2) how collateral bronchopulmonary circulation developed after acute embolisation of the lung with impaired(More)
The effects of acute and chronic application of ketamine on the resting spontaneous motility, its development and reactivity was studied in chick embryos of white Leghorns. 1. Acute application of ketamine (Narcamon) in a dose of 12.5 mg/kg e.w. partially depressed spontaneous motility as early as in 11-day old chick embryos. From day 15 of incubation(More)
The development of the chloride ion, glucose and total protein concentration was investigated in the cerebrospinal fluid of 11- to 21-day-old chick embryos and compared with their development in the blood plasma. Developmental changes in the chloride concentration in the plasma and CSF were very small, but it was always higher in the CSF than in the plasma.(More)
Rapid and sensitive detection is a key step in the effective and early response to the global hazard of various viral diseases. In this study, an integrated isolation of hepatitis B virus (HBV)-specific DNA fragment by magnetic nanoparticles (MNPs) and its immediate analysis by microchip CGE was performed. Microfluidic CE chip was used to accommodate the(More)
A high-performance liquid chromatographic (HPLC) method is described for the determination of ibuprofen in isolated erythrocytes and plasma. Before HPLC analysis ibuprofen was isolated by liquid-liquid extraction from these biological matrices; methylene chloride proved to be the best of the organic solvents tested. For the sample of erythrocytes it was(More)
