Acid‐Cleavable Poly(ethylene glycol) Hydrogels Displaying Protein Release at pH 5
2020
Abstract PEG is the gold standard polymer for pharmaceutical applications, however it lacks degradability. Degradation under physiologically relevant pH as present in endolysosomes, cancerous and inflammatory tissues is crucial for many areas. The authors present anionic ring‐opening copolymerization of ethylene oxide with 3,4‐epoxy‐1‐butene (EPB) and subsequent modification to introduce acid‐degradable vinyl ether groups as well as methacrylate (MA) units, enabling radical cross‐linking. Copolymers with different molar ratios of EPB, molecular weights (M n) up to 10 000 g mol−1 and narrow dispersities (Đ<1.05) were prepared. Both the P(EG‐co‐isoEPB)MA copolymer and the hydrogels showed pH‐…
Unexpected Behavior of Enaminones: Interesting New Routes to 1,6-Naphthyridines, 2-Oxopyrrolidines and Pyrano[4,3,2-de][1,6]naphthyridines
2012
Reaction of enaminones 1a&#8211;d with 2-aminoprop-1-ene-1,1,3-tricarbonitrile (2) in the presence of AcOH/NH4OAc afforded 7-amino-5-oxo-5,6-dihydro-1,6-naphthyridine-8-carbonitrile derivatives 9a&#8211;d. On the other hand, 2-aminopyrano[4,3,2-de] [1,6]naphthyridine-3-carbonitriles 20a&#8211;c,e were the only obtained products from the reactions of 1a&#8211;d with 2 in the presence of AcOH/NaOAc, while 1d afforded [3,5-bis-(4-chloro-benzoyl)-phenyl]-(4-chloro-phenyl)-methanone 21 under the same condition. The reaction of 2 with diethyl acetylenedicarboxylate in the presence of AcOH/NH4OAc afforded (4-cyano-5-dicyanomethylene-2-oxo-2,5-dihydro-1H-pyrrol-3-yl)-acetic acid eth…

Las obras musicales en las radios universitarias
2018
The Spanish General Audiovisual Communication Law does not relate to Campus Radio Stations. In this context, Copyright Collection Societies do not cover them in their catalogues of general fees. For this reason, the holders of these radios are forced to negotiate them. Althoug the Intellectual Property Law and the Order ECD/2574/2015, of 2 December, contain obligations for Copyright Collection Societies, on this matter its enforcement are far from being achieved
Usurarian contracts. Current jurisprudencial perspective
2018
El objetivo de este trabajo es destacar las novedades presentadas por la Jurisprudencia sobre contratos usurarios celebrados entre las empresas bancarias y sus clientes. La coexistencia de la Ley de Usura con las regulaciones para la protección de los consumidores contra cláusulas abusivas no ha menoscabado la vigencia de ley, pero sus diferencias en cuanto a la declaración de nulidad generan incertidumbre, por lo que sería conveniente una mayor armonización. The objective of this work is to highlight the novelties presented by the Jurisprudence on usurious contracts concluded between banking companies and their clients. The coexistence of the Usury Law with the regulations for the protecti…
Culturas de escola e excelência: entre a integração de todos e a distinção dos melhores
2018
Sem perder de vista a multidimensionalidade inerente aos percursos escolares, este texto procura refletir sobre a importância dos fatores organizacionais na construção dos resultados académicos. O enfoque incide sobre as dimensões intra-escolares, designadamente os efeitos da cultura de escola (nas suas diferentes facetas) e dos processos de liderança sobre a socialização dos estudantes. Optando por uma linha de pesquisa reflexiva, procura-se compreender os processos de construção de habitus (no sentido de Bourdieu) e os sistemas de disposições (na ótica de Lahire) estruturadores da cultura organizacional de escola. Do ponto de vista metodológico recorre-se a dados recolhidos no âmbito de u…
Influence de la symétrie et de la taille de la molécule adsorbée sur le processus d'adsorption des composés éthyléniques sur une zéolithe de topologi…
2005
This manuscript lies within the scope of the understanding of the stepped isotherm observed during adsorption, on MFI zeolites, of some organic compounds which have a similar size to that of the pore opening of zeolite. During this work, the process of adsorption of ethylene and tetramethylethylene is initially studied by gravimetry and then by in situ infrared spectroscopy. This last technique enables to follow simultaneously the modifications of the adsorbent and the adsorbate. The analysis of these data lets suppose that the step in adsorption isotherm can be explained by taking account simultaneously of the symmetry and the size of the admolecule. In addition to the infrared bands chara…
