ART DEMONSTRATES THAT FOOTBALL IS METASTASIZED, AND GIVES IT REFUGE

U ovom se radu problemski analiziraju obilježja nogometa u hit-romanu Alena Bovića Metastaze (2006) te u dvjema kasnijim obradama tog književnog djela – u kazališnoj predstavi Metastaze i istoimenom igranom filmu. Otuda ideja da se ondje zatečen, devijantnim pojavama obilježen nogomet, koji više baš i nema puno dodirnih točaka s igrom koja mu leži u korijenima, nazove metastaziralim. Umjetnička se stvarnost pritom promatra kao korespondentna društvenoj stvarnosti pa se za takvo etiketiranje nogometa prepoznaju razlozi na objema razinama. Na temelju takvog pristupa Metastazama, ali i na osnovi prethodno ponuđenog komparativnog uvida u nogometnu tematiku u nekim drugim književnim, kazališnim i filmskim ostvarenjima u Hrvatskoj i izvan nje, postavlja se teza o umjetnosti kao dokazu metastaziralog nogometa. No, još je izazovnije utvrditi može li umjetnost istodobno poslužiti i kao utočište metastaziralom nogometu tako da se njome revitalizira ponajprije estetska, ali istodobno i etička dimenzija tog sporta. Iz tih pobuda argumentacija u ovome radu uključuje tekstove i autore u širokom rasponu od književne kritike, antropologije igara i sociologije sporta do semiotike, kulturalnih studija i estetike.

Football as it appears in these three pieces is metastasized: it is deviant and in fact undergoes so many significant changes that it no longer has much in common with the original game. Artistic reality is seen as corresponding to social reality, and reasons for the metastasized nature of football are found on both levels. Based on the proposed analysis of Metastaze and a comparative analysis of descriptions of football in other books, plays and films in Croatia and abroad a hypothesis is put forward whereby art offers evidence as to the metastasized nature of football. A greater challenge still is to establish whether art might, at the same time, provide refuge to the metastasized football, revitalizing its aesthetic and ethical dimension. Given the scope of these claims, the arguments in the article are based on a wide array of texts and authors ranging from literary criticism, anthropology of games and sociology of sport to semiotics, cultural studies and aesthetics

Adenosine stress CMR T1-mapping detects early microvascular dysfunction in patients with type 2 diabetes mellitus without obstructive coronary artery disease

Background Type 2 diabetes mellitus (T2DM) is associated with coronary microvascular dysfunction in the absence of obstructive coronary artery disease (CAD). Cardiovascular magnetic resonance (CMR) T1-mapping at rest and during adenosine stress can assess coronary vascular reactivity. We hypothesised that the non-contrast T1 response to vasodilator stress will be altered in patients with T2DM without CAD compared to controls due to coronary microvascular dysfunction. Methods Thirty-one patients with T2DM and sixteen matched healthy controls underwent CMR (3 T) for cine, rest and adenosine stress non-contrast T1-mapping (ShMOLLI), first-pass perfusion and late gadolinium enhancement (LGE) imaging. Significant CAD (>50% coronary luminal stenosis) was excluded in all patients by coronary computed tomographic angiography. Results All subjects had normal left ventricular (LV) ejection and LV mass index, with no LGE. Myocardial perfusion reserve index (MPRI) was lower in T2DM than in controls (1.60 ± 0.44 vs 2.01 ± 0.42; p = 0.008). There was no difference in rest native T1 values (p = 0.59). During adenosine stress, T1 values increased significantly in both T2DM patients (from 1196 ± 32 ms to 1244 ± 44 ms, p < 0.001) and controls (from 1194 ± 26 ms to 1273 ± 44 ms, p < 0.001). T2DM patients showed blunted relative stress non-contrast T1 response (T2DM: ΔT1 = 4.1 ± 2.9% vs. controls: ΔT1 = 6.6 ± 2.6%, p = 0.007) due to a blunted maximal T1 during adenosine stress (T2DM 1244 ± 44 ms vs. controls 1273 ± 44 ms, p = 0.045). Conclusions Patients with well controlled T2DM, even in the absence of arterial hypertension and significant CAD, exhibit blunted maximal non-contrast T1 response during adenosine vasodilatory stress, likely reflecting coronary microvascular dysfunction. Adenosine stress and rest T1 mapping can detect subclinical abnormalities of the coronary microvasculature, without the need for gadolinium contrast agents. CMR may identify early features of the diabetic heart phenotype and subclinical cardiac risk markers in patients with T2DM, providing an opportunity for early therapeutic intervention

Molecular imaging with optical coherence tomography using ligand-conjugated microparticles that detect activated endothelial cells: Rational design through target quantification

OBJECTIVES: Optical coherence tomography (OCT) is a high resolution imaging technique used to assess superficial atherosclerotic plaque morphology. Utility of OCT may be enhanced by contrast agents targeting molecular mediators of inflammation. METHODS AND RESULTS: Microparticles of iron oxide (MPIO; 1 and 4.5 μm diameter) in suspension were visualized and accurately quantified using a clinical optical coherence tomography system. Bound to PECAM-1 on a plane of cultured endothelial cells under static conditions, 1 μm MPIO were also readily detected by OCT. To design a molecular contrast probe that would bind activated endothelium under conditions of shear stress, we quantified the expression (basal vs. TNF-activated; molecules μm(-2)) of VCAM-1 (not detected vs. 16 ± 1); PECAM-1 (132 ± 6 vs. 198 ± 10) and E-selectin (not detected vs. 46 ± 0.6) using quantitative flow cytometry. We then compared the retention of antibody-conjugated MPIO targeting each of these molecules plus a combined VCAM-1 and E-selectin (E+V) probe across a range of physiologically relevant shear stresses. E+V MPIO were consistently retained with highest efficiency (P &lt; 0.001) and at a density that provided conspicuous contrast effects on OCT pullback. CONCLUSION: Microparticles of iron oxide were detectable using a clinical OCT system. Assessment of binding under flow conditions recommended an approach that targeted both E-selectin and VCAM-1. Bound to HUVEC under conditions of flow, targeted 1 μm E+V MPIO were readily identified on OCT pullback. Molecular imaging with OCT may be feasible in vivo using antibody targeted MPIO
