A 51-year-old man presented with right orbital pain and Horner syndrome three weeks previously. Although magnetic resonance imaging (MRI) showed no intracranial abnormalities, time-of-flight imaging of MR angiography (Picture A) detected an intimal flap and T1-weighted imaging (Picture B) indicated an intramural hematoma in the right internal carotid artery (ICA) at the cervical segment. Threed...

The article examines feminatives as a semantic and word-formation category. In Slavic languages are mainly regarded modificational derivatives formed from masculine by the whole replacement of suffix (bor-(-ec/-k?), partial (bra-l/(-ec/-ka), or adding feminine to (miz-ar/-ka). Due expansion global communication through mass media, inevitable broadening vocabulary requires adaptation borrowed wo...

The idea of the InterCriteria Analysis (ICA) was generated by authors in 2014. For next (already 9) years, ICA has been an object intensive research and applications. In present paper, extension is introduced. it, criteria or objects have their own weight coefficients, priorities. particular case, when these coefficients are equal to 1, standard appears.

BACKGROUND The regulation of PTH secretion by calcium is altered in patients with primary hyperparathyroidism (HPT). A similar abnormality may occur in secondary HPT, but comparisons of PTH secretion in normal subjects and those with secondary HPT have given contrasting results. Differences in baseline serum ionized calcium (ICa) may partly account for these conflicting results. The aim of the ...

BACKGROUND Measuring blood calcium level is recommended in haemodialysis (HD) patients. The Kidney Disease Improving Global Outcomes position states that the measurement of ionized calcium (ICa) level is preferred, but in the clinical setting, due to technical difficulties, total calcium (tCa) level is preferred to ICa. AIM The aim of this study was to test the possibility of delayed ICa anal...

Voltage-gated L-type Ca(2+) current (ICa,L) induces contraction of arterial smooth muscle cells (ASMCs), and ICa,L is increased by H2O2 in ASMCs. Superoxide released from the mitochondrial respiratory chain (MRC) is dismutated to H2O2 We studied whether superoxide per se acutely modulates ICa,L in ASMCs using cultured A7r5 cells derived from rat aorta. Rotenone is a toxin that inhibits complex ...

BACKGROUND AND PURPOSE The presence and importance of hemodynamic factors to the beneficial effect of carotid endarterectomy (CEA) in patients with severe stenosis of the internal carotid artery (ICA) is unclear. The purpose of this study was to investigate possible hemodynamic changes caused by a severe ICA stenosis and the subsequent changes after CEA. METHODS Hemodynamic parameters were ac...

Despite the growing use of independent component analysis (ICA) algorithms for isolating and removing eyeblink-related activity from EEG data, we have limited understanding of how variability associated with ICA uncertainty may be influencing the reconstructed EEG signal after removing the eyeblink artifact components. To characterize the magnitude of this ICA uncertainty and to understand the ...

BACKGROUND AND PURPOSE We attempted ultrasonographic evaluation of the distal extracranial internal carotid artery (ICA) using the transoral method (transoral carotid ultrasonography [TOCU]). METHODS The subjects consisted of five healthy volunteers and seven stroke patients. Examinations were performed with a color Doppler flow imaging system equipped with convex array transducers (7 or 9.5 ...
