Architettura e verità. Emil Steffann architetto di chiese

La ricerca pone al suo centro lo studio dell'opera architettonica di Emil Steffann (1899-1968) la cui produzione realizzata consta, nel breve arco temporale che va dal 1950 al 1968, del ragguardevole numero di trentanove chiese, rappresentando un caso emblematico di progettazione e costruzione di edifici per il culto cristiano in grado di raffigurarne concretamente i principi fondativi liturgici, estetici e morfologici. L'architettura di Steffann, profondamente ispirata dallo spirito religioso, legata a figure primigenie che plasmano lo stare-insieme della comunità nella qualità corporea della materia, dove la presenza liturgica e monumentale si esprime nel silenzio e nella disponibilità di uno spazio circoscritto dai muri e direzionato dalla luce, concorre a definire nell'oggettivo amore per il vero la percezione estetico-teologica e la poetica formativa che connaturano, a nostro parere, progetto e segno della chiesa. Il testo concretizza il primo studio monografico completo di questo corpus architettonico e si basa sulla ricognizione diretta delle opere di Steffann; ne è derivata una narrazione non conseguente a un ordine cronologico o di presupposta importanza degli edifici, bensì che ricerca ed evidenzia corrispondenze tra nodi di una rete ideativa la quale, con diversi gradi di finitezza, in punti non sempre omogenei del tempo e dello spazio, denota un'esperienza autentica del comporre e del costruire. Il racconto individua gli oggetti architettonici, ne discute la consistenza aprendosi a riferimenti altri (in particolare il pensiero ecclesiologico-liturgico di Romano Guardini e quello estetico-teologico di Hans Urs von Balthasar) in grado di illuminarne la genesi e la manifestazione, li lega infine in sequenze analogiche. Una serie di tavole fotografiche originali, parte ineludibile e integrante della ricerca, testimonia dello stato attuale dei luoghi, connotando ulteriormente l'aspetto info-rappresentativo della loro composizione architettonica. In chiusura, la sintesi architetturale vuole essere uno strumento di verifica e progetto, quindi di trasposizione futura, correlato all'elaborazione documentaria.

Esophageal Dilation in Eosinophilic Esophagitis: Effectiveness, Safety, and Impact on the Underlying Inflammation

Esophageal dilation often leads to long-lasting relief of dysphagia in eosinophilic esophagitis (EoE). The aim of this study was to define the effectiveness, safety, and patient acceptance of esophageal dilation in EoE. In addition, we examined the influence of dilation on the underlying esophageal inflammation.

Catheter ablation of recurrent scar-related ventricular tachycardia using electroanatomical mapping and irrigated ablation technology: results of the prospective multicenter Euro-VT-study

Ventricular tachycardia (VT) late after myocardial infarction is an important contributor to morbidity and mortality. This prospective multicenter study assessed the efficacy and safety of electroanatomical mapping in combination with open-saline irrigated ablation technology for ablation of chronic recurrent mappable and unmappable VT in remote myocardial infarction.

Budesonide is effective in adolescent and adult patients with active eosinophilic esophagitis

Eosinophilic esophagitis (EoE) is a chronic inflammatory disease of the esophagus characterized by dense tissue eosinophilia; it is refractory to proton pump inhibitor therapy. EoE affects all age groups but most frequently individuals between 20 and 50 years of age. Topical corticosteroids are effective in pediatric patients with EoE, but no controlled studies of corticosteroids have been reported in adult patients.

One-Step (18)F-Labeling of Carbohydrate-Conjugated Octreotate-Derivatives Containing a Silicon-Fluoride-Acceptor (SiFA): In Vitro and in Vivo Evaluation as Tumor Imaging Agents for Positron Emission Tomography (PET)

The synthesis, radiolabeling, and initial evaluation of new silicon-fluoride acceptor (SiFA) derivatized octreotate derivatives is reported. So far, the main drawback of the SiFA technology for the synthesis of PET-radiotracers is the high lipophilicity of the resulting radiopharmaceutical. Consequently, we synthesized new SiFA-octreotate analogues derivatized with Fmoc-NH-PEG-COOH, Fmoc-Asn(Ac?AcNH-?-Glc)-OH, and SiFA-aldehyde (SIFA-A). The substances could be labeled in high yields (38 ± 4%) and specific activities between 29 and 56 GBq/?mol in short synthesis times of less than 30 min (e.o.b.). The in vitro evaluation of the synthesized conjugates displayed a sst2 receptor affinity (IC?? = 3.3 ± 0.3 nM) comparable to that of somatostatin-28. As a measure of lipophilicity of the conjugates, the log P(ow) was determined and found to be 0.96 for SiFA-Asn(AcNH-?-Glc)-PEG-Tyr³-octreotate and 1.23 for SiFA-Asn(AcNH-?-Glc)-Tyr³-octreotate, which is considerably lower than for SiFA-Tyr³-octreotate (log P(ow) = 1.59). The initial in vivo evaluation of [¹?F]SiFA-Asn(AcNH-?-Glc)-PEG-Tyr³-octreotate revealed a significant uptake of radiotracer in the tumor tissue of AR42J tumor-bearing nude mice of 7.7% ID/g tissue weight. These results show that the high lipophilicity of the SiFA moiety can be compensated by applying hydrophilic moieties. Using this approach, a tumor-affine SiFA-containing peptide could successfully be used for receptor imaging for the first time in this proof of concept study.

Trauma mechanisms, patterns of injury, and outcomes in a retrospective study of 71 burns from civil gas explosions

Although explosion injuries caused by terror attacks or in war are evaluated in many studies, limited information about civil explosion injuries can be found in the literature.

Icatibant, a new bradykinin-receptor antagonist, in hereditary angioedema

Hereditary angioedema is characterized by recurrent attacks of angioedema of the skin, larynx, and gastrointestinal tract. Bradykinin is the key mediator of symptoms. Icatibant is a selective bradykinin B2 receptor antagonist.

The inotropic peptide ?ARKct improves ?AR responsiveness in normal and failing cardiomyocytes through G(??)-mediated L-type calcium current disinhibition

The G(βγ)-sequestering peptide β-adrenergic receptor kinase (βARK)ct derived from the G-protein-coupled receptor kinase (GRK)2 carboxyl terminus has emerged as a promising target for gene-based heart failure therapy. Enhanced downstream cAMP signaling has been proposed as the underlying mechanism for increased β-adrenergic receptor (βAR) responsiveness. However, molecular targets mediating improved cardiac contractile performance by βARKct and its impact on G(βγ)-mediated signaling have yet to be fully elucidated.
