The Greek Crown Games

The crowns of the four major Panhellenic crown games reveal the religious and symbolic meaning of the plants of whose leaves they were made. Special attention will also be paid to the historical, political, and socio-economic reasons why these four festivals became the most prestigious and popular in the Greek world from the archaic period onwards. Texts and inscriptions reveal many organizational features of the games. The wider regional function of the festivals is evidenced even in organization. The games were also important occasions for trading, for communicating news of international relevance, for announcing military and political initiatives and building up alliances, or for advertising literary and artistic works. Victor lists, ‘archival documents’, monuments and dedications at the sites preserved public memories and created cultural unities. The prestige of crown games was shared by many local games designated as ‘isolympic’, ‘isopythian’, and so on during the Hellenistic and Roman periods.

Altered Static and Dynamic Voxel-mirrored Homotopic Connectivity in Patients With Frontal Glioma

Contralateral regions play critical role in functional compensation in glioma patients. Voxel-mirrored homotopic connectivity (VMHC) characterizes the internal functional connectivity of the brain, which is considered to have a regional functional basis. This study aims to investigate the alterations of brain regional function and VMHC in patients with frontal glioma, and further investigate physiological significance of these alterations. We enrolled 22 patients with frontal glioma and 22 demography matched healthy controls (HC). We determined degree centrality (DC), regional homogeneity (ReHo), and VMHC to investigate the alterations of regional function and internal functional connectivity in patients. Furthermore, partial correlation analysis was conducted to explore the relationship between these indicators and cognitive functions.Compared with HC, patients showed decrease in static VMHC, DC, ReHo and dynamic ReHo (dReHo) within right middle frontal gyrus (MFG.R), left middle frontal gyrus (MFG.L), right precuneus(PCUN.R), left precuneus(PCUN.L), left limbic lobe (LIMB.L), right superior frontal gyrus (SFG.R), right postcentral gyrus (POCG.R), right inferior parietal lobule (IPL.R), but increase in dynamic VMHC (dVMHC) within PCUN.R and PCUN.L. Meanwhile, MFG.R with decreased VMHC, LIMB.L with decreased DC, LIMB.L with decreased ReHo, and PCUN.R with increased dVMHC were significantly positively correlated with cognitive function, but the SFG.R with decreased DC was significantly negatively correlated with memory. This study preliminarily confirmed glioma not only cause regional dysfunction, but also disturb long-distance functional connectivity, and the long-distance functional connectivity showed strong instability in patients with frontal glioma. Meanwhile, the altered functional indicators may compensate cognitive function in patients with frontal glioma.

Evaluation of systolic LV function and LV mechanics

Analysis of global and regional left ventricular (LV) function is the most frequent indication to perform echocardiography. While visual assessment based on 2D images is the basis for analysis of LV function, it may be supplemented by quantitative techniques to obtain parameters of global or regional function. 2D echocardiography tends to underestimate LV volumes compared to cardiac magnetic resonance (CMR), 3D echocardiography results in less volume underestimation and high accuracy in the analysis of ejection fraction. Visual analysis of regional function is limited by significant interobserver variability. Another approach to systolic LV function is the assessment of LV mechanics, typically by measuring global longitudinal deformation (strain) by speckle-tracking echocardiography. Alternatively, information on deformation can be obtained from CMR (currently, mostly by feature tracking). Deformation parameters detect early impairment of LV systolic function with higher sensitivity than ejection fraction. While echocardiography continues to be the first-choice modality for ejection fraction, CMR has become the gold standard for quantification of LV volumes and ejection fraction. Nuclear imaging should be applied to assess LV function only if simultaneous assessment of myocardial perfusion is requested.

Hierarchia i relacje miast w województwie lubuskim

In socio-economic geography any regional settlement system makes one of its majorfactors of development. It is towns that play a specific role in this system, the meaning of which canbe approached from different perspectives. This paper focuses on the hierarchies and relationshipsbetween towns in the Province of Lubuskie seen from the spatial point of view. The volume and sequence rule of Zipf ’s law as well as the gravitation model have been used as the statistical tools. Thedata valid as in 2015 were accounted for in the analysis. Results from the empirical studies show thatdespite a similar urban density in Lubuskie Province and generally across Poland, the town system in theregion is visibly specific. Apart from two largest cities playing a regional and cross-regional function,i.e. Zielona Góra and Gorzów Wlkp., the issue of how small and middle-sized towns function in theprovince comes to the fore.
