N,N′-Bis(pyridin-2-yl)octanediamide

2016

The complete molecule of the title compound, C18H22N4O2, is generated by crystallographic inversion symmetry. In the crystal, N—H...N hydrogen bonds connect the molecules into [010] chains, which featureR22(8) loops. The packing is consolidated by C—H...O interactions.

N-(Pyrazin-2-yl)adamantane-1-carboxamide

2016

Molecules of the title compound, C15H19N3O, are composed of an adamantine unit and a pyrazine ring connected to each other through an amide bond. The H—N—C=O moiety is close to planar [C—N—C—O and C—N—C—C torsion angles of 4.7 (2) and −173.8 (1)°, respectively]. The N3—C5 bond has partial double-bond character [1.370 (1) Å]. The geometries of the pyrazine ring and the adamantane substituent are normal and in good agreement with closely related structures. In the crystal, molecules are connected by N—H...O hydrogen bonds, forming zigzag chains in the [001] direction and are arranged in a herringbone fashion.

L'incrinatura del principio concordatario in materia matrimoniale. Rilievi critici sulla prolungata convivenza come limite alla delibazione

Considerazioni e prospettive storico-giuridiche sul recente accordo Santa Sede - Italia in materia di riconoscimento dei titoli ecclesiastici.

2020

The study is concerned with analyzing from both a historical and a legal point of view the recognition of ecclesiastical academic titles in light of the agreements between the Holy See and Italy. More precisely, it deals with the process that, from art. 10, paragraph 2 of the “Villa Madama Agreements”, has led, thanks to the Lisbon Convention and the so-called “Bologna Process”, to the agreement of February 13, 2019.

Receptor for advanced glycation end products is subjected to protein ectodomain shedding by metalloproteinases.

2008

The receptor for advanced glycation end products (RAGE) is a 55-kDa type I membrane glycoprotein of the immunoglobulin superfamily. Ligand-induced up-regulation of RAGE is involved in various pathophysiological processes, including late diabetic complications and Alzheimer disease. Application of recombinant soluble RAGE has been shown to block RAGE-mediated pathophysiological conditions. After expression of full-length RAGE in HEK cells we identified a 48-kDa soluble RAGE form (sRAGE) in the culture medium. This variant of RAGE is smaller than a 51-kDa soluble version derived from alternative splicing. The release of sRAGE can be induced by the phorbol ester PMA and the calcium ionophore c…

Retinoids as a Perspective in Treatment of Alzheimer’s Disease

2010

<i>Background:</i> In the past, we demonstrated that the disintegrin metalloproteinase ADAM10 has α-secretase activity in vitro and in cultured cells. We also found out that moderate overexpression of this proteinase inhibits Aβ peptide production and prevents the formation of amyloid plaques in an Alzheimer’s disease (AD) mouse model. Moreover, it corrects early hippocampal defects like LTP impairment and increases cortical synaptogenesis. <i>Objective:</i> Upregulation of ADAM10 might be an alternative approach concerning AD therapy. Our current research therefore focuses on substances and/or pathways which regulate ADAM10 gene expression. <i>Methods:</i&g…

Melatonin stimulates the nonamyloidogenic processing ofβAPP through the positive transcriptional regulation of ADAM10 and ADAM17

2014

Melatonin controls many physiological functions including regulation of the circadian rhythm and clearance of free radicals and neuroprotection. Importantly, melatonin levels strongly decrease as we age and patients with Alzheimer's disease (AD) display lower melatonin than age-matched controls. Several studies have reported that melatonin can reduce aggregation and toxicity of amyloid-β peptides that are produced from the β-amyloid precursor protein (βAPP). However, whether melatonin can directly regulate the βAPP-cleaving proteases ('secretases') has not been investigated so far. In this study, we establish that melatonin stimulates the α-secretase cleavage of βAPP in cultured neuronal an…

Enfermedad de Adamantiades-Behçet: Un proceso enigmático con manifestaciones orales

2006

La enfermedad de Adamantiades-Behçet es una vasculitis multisistémica crónica, potencialmente capaz de afectar a cualquier órgano o sistema del cuerpo humano y en la que la aparición repetida de úlceras orales es una de sus principales expresiones clínicas. La EAB es una patología de carácter universal, con una prevalencia variable en función de la población estudiada y que muestra una curiosa distribución geográfica. A pesar de ser un proceso conocido desde la antigüedad, su etiopatogenia en la que probablemente se hayan implicados factores genéticos, microbiológicos e inmunológicos, continua siendo enigmática. Su amplio espectro de manifestaciones clínicas orales, genitales, cutáneas, ocu…

La voce del corpo: Madam Orlan e la soma-estetica

2013

Oggi la società dello spettacolo ha ridato nuova centralità al corpo e alla sua bellezza. Ciò trova riscontro non solo nei modelli imposti dagli schermi televisivi, ma anche dalla maggiore attenzione che le donne prestano al proprio corpo, ricorrendo sempre più spesso alla chirurgia estetica. Questo intervento, a partire dalle teorie del filosofo americano Richard Shusterman, fondatore della somaestetica, vuole indagare la centralità del corpo nella riflessione estetica contemporanea, prendendo spunto da una famosa artista francese della seconda metà del Novecento: Madame Orlan. Questa artista, che ha operato nell’ambito della Body Art, ha sottoposto a dura critica il modello occidentale di…
