Magnetoencephalography (MEG) and electroencephalography (EEG) are contemporary methods to investigate the function and organization of the brain. Simultaneously acquired MEG-EEG data are inherently multi-dimensional and exhibit coupling. This study uses a coupled tensor decomposition to extract the signal sources from MEG-EEG during intermittent photic stimulation (IPS).

Patients And Methods: Over the period from October to December 2018, the specialists of our Centre performed a total of 90 internal carotid artery stenting procedures in 83 patients (of these, 7 patients underwent bilateral staged stenting of both internal carotid arteries) using intravascular ultrasound in order to assess intraoperative protrusion of an atherosclerotic plaque through the implanted stent. The patients' age varied from 42 to 87 (mean 68.
Diagnosis of dilation (D) cardiomyopathy (CMP) requires exclusion not only of inflammatory and genetically determined forms but also of some rare diseases. This 51 year old patient with history of moderate arterial hypertension approached a cardiologist because of new onset atrial fibrillation and dyspnea. Echocardiography detected dilation of all cardiac chambers with relatively preserved ejection fraction, causing suspicion of DCMP.

Polyploidy is a key factor in the evolution of higher plants and plays an important role in the variation of plant genomes, leading to speciation in some cases. During polyploidisation, different balancing processes take place at the genomic level that can promote variation in nuclear DNA content. We estimated genome size using flow cytometry in 84 populations of 67 Artemisia species and one population of Crossostephium chinense.

The aim of our study was to survey these and other traits in multiple closely related but independently evolved lineages of Artemisia. Our phylogenetic study was based on 133 taxa using 3'-ETS and ITS, and on data on morphology, karyology, distribution, and ecological preferences.
