Mallarmé and His Futurist 'Heir' Marinetti

Marinetti is known for his call to arms against Mallarmé's aesthetics, but, in actual fact, he admired the great Symbolist at the beginning of his literary career. Nevertheless, his heritage from Mallarmé was not pure. This becomes most apparent in their diverging attitude towards the book as a cultural attainment and a literariy vehicle. While Mallarmé's Book was organized according to the model of the constellation, where all elements answer each other in a system of echoes, the Futurist text was characterized by the absence of both memory and echoes between the different parts of the book.]

Das Werk als Feige und als Figur. Ambivalenzen der Rezeption zwischen Valéry, Mallarmé, "Tel Quel" und Francis Ponge

L’œuvre poétique de Valéry est caractérisée par une esthétique de la perfection, de la pureté et de la clôture. La série ouverte et hétérogène des "Cahiers", en revanche, ne se laisse guère ranger dans la catégorie de l’œuvre. Selon Valéry, la réorientation intellectuelle à la base de cette opposition est due au "choc" subi par la découverte de l’œuvre mallarméenne. Les divers écrits valéryens sur Mallarmé nous servent à reconstruire cette relation ambivalente et nous aident à éclairer sa conception non moins ambivalente de l’œuvre d’art. Nous soutenons que ce ne sont pas ses propres travaux, mais les poésies de Mallarmé qui lui semblaient des œuvres achevées à proprement parler. Pour décrire l’expérience de perfection et d’achèvement que lui fournit la lecture du "Coup de dés", Valéry se sert de la notion de figure qui, entre autres, comporte des associations géométriques. Sous la forme d’un hommage ambivalent, Francis Ponge oppose aux concepts valéryens de figure et d’œuvre d’art une poétique de l’objet matériel et concret qui s’incarne dans "La figue (sèche)", publiée en 1960 comme pièce inaugurale de la revue "Tel Quel".

Myocardial injection of skeletal myoblasts impairs contractility of host cardiomyocytes

BACKGROUND: Mechanisms underlying improvement of myocardial contractile function after cell therapy as well as arrhythmic side effect remain poorly understood. We hypothesised that cell therapy might affect the mechanical properties of isolated host cardiomyocytes. METHODS: Two weeks after myocardial infarction (MI), rats were treated by intramyocardial myoblast injection (SkM, n=8), intramyocardial vehicle injection (Medium, n=6), or sham operation (Sham, n=7). Cardiac function was assessed by echocardiography. Cardiomyocytes were isolated in a modified Langendorff perfusion system, their contraction was measured by video-based inter-sarcomeric analysis. Data were compared with a control-group without myocardial infarction (Control, n=5). RESULTS: Three weeks post-treatment, ejection fraction (EF) further deteriorated in vehicle-injected and non-injected rats (respectively 40.7+/-11.4% to 33+/-5.5% and 41.8+/-8% to 33.5+/-8.3%), but was stabilised in SkM group (35.9+/-6% to 36.4+/-9.7%). Significant cell hypertrophy induced by MI was maintained after cell therapy. Single cell contraction (dL/dt(max)) decreased in SkM and vehicle groups compared to non-injected group as well as cell shortening and relaxation (dL/dt(min)) in vehicle group. A significantly increased predisposition for alternation of strong and weak contractions was observed in isolated cardiomyocytes of the SkM group. CONCLUSION: Our study provides the first evidence that injection of materials into the myocardium alters host cardiomyocytes contractile function independently of the global beneficial effect of the heart function. These findings may be important in understanding possible adverse effects.

Impact of stent overlap on angiographic and long-term clinical outcome in patients undergoing drug-eluting stent implantation

Objectives We compared the angiographic and long-term clinical outcomes of patients with and without overlap of drug-eluting stents (DES). Background DES overlap has been associated with delayed healing and increased inflammation in experimental studies, but its impact on clinical outcome is not well established. Methods We analyzed the angiographic and clinical outcomes of 1,012 patients treated with DES in the SIRTAX (Sirolimus-Eluting Versus Paclitaxel-Eluting Stents for Coronary Revascularization) trial according to the presence or absence of stent overlap and the number of stents per vessel: 134 (13.2%) patients with multiple DES in a vessel with overlap, 199 (19.7%) patients with multiple DES in a vessel without overlap, and 679 (67.1%) patients with 1 DES per vessel. Results Angiographic follow-up at 8 months showed an increased late loss in DES overlap patients (0.33 ± 0.61 mm) compared with the other groups (0.18 ± 0.43 mm and 0.15 ± 0.38 mm, p < 0.01). The smallest minimal lumen diameter was located at the zone of stent overlap in 17 (68%) of 25 patients with stent overlap who underwent target lesion revascularization. Major adverse cardiac events were more common in patients with DES overlap (34 events, 25.4%) than in the other groups (42 events, 21.1% and 95 events, 14.0%) at 3 years (p < 0.01). Both the risk of target lesion revascularization (20.2% vs. 16.1% vs. 9.7%, p < 0.01) and the composite of death or myocardial infarction (17.2% vs. 14.1% vs. 9.1%, p = 0.01) were increased in patients with DES overlap compared with the other groups. Conclusions DES overlap occurs in >10% of patients undergoing percutaneous coronary intervention in routine clinical practice and is associated with impaired angiographic and long-term clinical outcome, including death or myocardial infarction.

Impact of arterial injury on neointimal hyperplasia after implantation of drug-eluting stents in coronary arteries: an intravascular ultrasound study

Aims: We investigated the impact of arterial injury on neointimal hyperplasia following implantation of drug-eluting stents (DES). Methods and results: A total of 196 patients with 223 segments (sirolimus-eluting stents [SES]: 104, paclitaxel-eluting stents [PES]: 119) underwent intravascular ultrasound eight months after DES implantation. Arterial injury was defined as the balloon-to-artery ratio (BAR). Segments were categorised into two groups: high BAR defined as BAR>1.1 (120 segments), and low BAR defined as BAR ≤1.1 (103 segments). Baseline clinical characteristics were similar for both groups. Although reference vessel diameter was smaller, stent diameter, maximal balloon pressure and balloon diameter were higher in the high BAR compared with the low BAR group. Lumen (7.10±1.91 vs. 6.25±1.69, p=0.001), stent (7.31±1.95 vs. 6.41±1.80, p=0.001), and external elastic membrane (17.1±4.9 vs. 14.8±4.0, p<0.0001) areas (mm2) were higher, but neointimal hyperplasia (0.21±0.36 vs. 0.16±0.48, p=0.42) area (mm2) was similar in the high BAR compared with the low BAR group. Arterial injury as assessed by BAR was not associated with the amount of neointimal hyperplasia (R2=0.003, p=0.40). Conclusions: Arterial injury does not correlate with the amount of neointimal hyperplasia following DES implantation. Conventionally aggressive DES implantation techniques do not adversely affect long-term outcome with respect to restenosis. - See more at: http://www.pcronline.com/eurointervention/30th_issue/79/#sthash.1do4X31G.dpuf

Dual low response to acetylsalicylic acid and clopidogrel is associated with myonecrosis and stent thrombosis after coronary stent implantation

Impaired response to antiplatelet therapy with acetylsalicylic acid (ASA) and clopidogrel (CLO) has been associated with an increased risk of stent thrombosis and ischemic events after coronary stent implantation. We sought to investigate whether patients with a low response (LR) to ASA or CLO are at increased risk for periprocedural and short-term ischemic events after coronary stent implantation.

[Acute myocardial infarction: importance of the networking in the initial management]

Early reperfusion with prompt re-establishment of coronary blood flow improves survival in patients suffering from acute ST-elevation myocardial infarction (STEMI). Leaving systemic thrombolysis for primary percutaneous coronary intervention (PCI) is justified by clinical results in favor of PCI. Nevertheless, primary PCI necessitates additional transfer time and requires an efficient territorial networking. The present article summarizes the up-to-dated management of patients with acute STEMI and/or overt cardiogenic shock.
