Isoprostanes (IsoPs) are key biomarkers for investigating the role of free radical generation in the pathogenesis of human disorders. To solve IsoPs-related problems with regard to isoprostanes, analytical tools are required. This paper reviews the problems and trends in this field focusing on the methodology for assaying biomarkers in exhaled breath(More)
BACKGROUND Haemodialysis (HD) and peritoneal dialysis (PD) should be regarded as complementary methods of renal replacement therapy. Approximately 10-20% of patients on PD are transferred annually to HD due to technique failure. Much smaller proportion of patients changes modality from HD to PD, predominantly due to vascular access problems, cardiac disease(More)
PURPOSE The aim of the study was to assess changes in subarachnoid space width (sas-TQ), the marker of intracranial pressure (ICP), pial artery pulsation (cc-TQ) and cardiac contribution to blood pressure (BP), cerebral blood flow velocity (CBFV) and cc-TQ oscillations throughout the maximal breath hold in elite apnoea divers. Non-invasive assessment of(More)
OBJECTIVE We investigated the effect of pharmacologic (steroids, vasodilators, vitamins, and Betaserc) and hyperbaric oxygen therapy on patients with sudden sensorineural hearing loss. METHODS The pharmacologic arm of the study consisted of 52 patients with defined sudden sensorineural hearing loss treated simultaneously in the ENT Department and National(More)
The paper presents an analysis of correlation between heart rate (HR) and blood pressure (BP). The actual data were obtained from three female and one male. The systolic and diastolic blood pressure was measured with the invasive method in the radial artery. The correlation coefficient indicates only linear dependence, so the inverse of HR was also taken(More)
INTRODUCTION Reactive oxygen species are involved in the functional changes necessary for synaptic plasticity, memory, and cognitive function. It is far from clear whether the increased excitability, and which forms of neuronal excitability, should be considered a part of the learning process or, rather, cellular manifestation of neuronal oxygen poisoning.(More)
INTRODUCTION Using a novel method called near-infrared transillumination backscattering sounding (NIR-T/BSS) that allows for the non-invasive measurement of pial artery pulsation (cc-TQ) and subarachnoid width (sas-TQ) in humans, we assessed the influence of sympathetic activation on the cardiac and respiratory contribution to blood pressure (BP) cc-TQ(More)
A serious diving accident can occur in recreational diving even in countries where diving is not very popular due to the fact that diving conditions there are not as great as in some tropical diving locations. The estimated number of injured divers who need recompression treatment in European hyperbaric facilities varies between 10 and 100 per year(More)
The aim of our study was the evaluation of a pressure prediction method, which was based on Taylor series. The pressure value was predicted basing on its past values, which were weighted by coefficients calculated according to the Taylor series approximation. The advantage of such approach was possibility of non-uniform pressure measurements. The main(More)
High-pressure injection injury (HPII) is a rare severe hand trauma associated with high rates of complications and amputations of the peripheral parts of the fingers and permanent hand dysfunction. Early detection and treatment are crucial as any delay may result in a considerable functional deficit of the affected limb or amputation. The rate of amputation(More)
