Apatridia. Protección internacional y reconocimiento de su estatuto jurídico en España
2020
La apatridia es una vulneración de derechos humanos que afecta a millones de personas en el mundo y a miles en España. No se trata solo del incumplimiento del derecho humano a una nacionalidad, sino de todos los demás que exigen la posesión de una para ser ejercitados en la práctica de forma efectiva. La nacionalidad moderna, entendida como vínculo jurídico entre la persona y el Estado a través del cual este le reconoce derechos y deberes, es una institución que ejerce de frontera, al actuar como elemento clave para delimitar la soberanía personal de aquel Estado. Así, hereda los componentes de inclusión y, a la vez, exclusión de la ciudadanía clásica, a la cual reemplaza. Hoy se entiende p…

Everyday Objects
2014
Il presente numero di Aisthesis, che ha come titolo “Everyday Objects / Oggetti quotidiani”, muove da una constatazione di fatto. Oggi la plasmazione del gusto avviene, in misura notevole e forse preminente, attraverso il rapporto con oggetti d’uso che, a differenza delle opere d’arte celebrate da élites culturali in luoghi e tempi circoscritti (ma spesso fruite come oggetti per il consumo turistico di massa), hanno un ruolo pervasivo nelle varie attività della vita quotidiana, da quelle domestiche a quelle lavorative, al tempo libero. Tuttavia a causa della loro prosaicità gli oggetti quotidiani solo raramente sono stati al centro della riflessione filosofica. Così, nell’epoca attuale in c…
Il gravis morbus degli scholastici. Esempi tratti dalla storia (e dall’arte) nell’opera di Seneca il Vecchio
2021
Within a broader reflection on the presence of history in declamatory literature, the paper deals with some of Seneca’s controversies in which the thema concerns undisputed protagonists of ancient art, observing the way in which declaimers converge within the fields of interest of the school fundamental reflections on issues related to art and the role of the artist.
The ascidian prophenoloxidase activating system
2009
Phenoloxidases/tyrosinases initiate melanin synthesis in almost all organisms, and are involved in different biological activities such as the colour change of human hair and the browning or blackening of fruit skin etc. In many invertebrates, defence reactions are linked to phenoloxidase activity and/or melanization. Contacts with foreign molecules are able to trigger the prophenoloxidase (proPO) system that requires serine protease cleavage for activating the zymogen to phenoloxidase (PO). It is generally accepted that the proPO system is fully expressed in arthropods, and, recently, progress in the regulation of crustacean and insect proPO activation steps have been achieved. After cells…

Yeast Killer Toxin-Like Candidacidal Ab6 Antibodies Elicited through the Manipulation of the Idiotypic Cascade
2014
A mouse anti-anti-anti-idiotypic (Id) IgM monoclonal antibody (mAb K20, Ab4), functionally mimicking a Wyckerhamomyces anomalus (Pichia anomala) killer toxin (KT) characterized by fungicidal activity against yeasts presenting specific cell wall receptors (KTR) mainly constituted by β-1,3-glucan, was produced from animals presenting anti-KT Abs (Ab3) following immunization with a rat IgM anti-Id KT-like mAb (mAb K10, Ab2). MAb K10 was produced by immunization with a KT-neutralizing mAb (mAb KT4, Ab1) bearing the internal image of KTR. MAb K20, likewise mAb K10, proved to be fungicidal in vitro against KT-sensitive Candida albicans cells, an activity neutralized by mAb KT4, and was capable of…
Dietary polyphenols as antidiabetic agents: Advances and opportunities
2020
Abstract Dietary polyphenols have been widely investigated as antidiabetic agents in cell, animals, human study, and clinical trial. The number of publication (Indexed by Web of Science) on “polyphenols and diabetes” significantly increased since 2010. This review highlights the advances and opportunities of dietary polyphenols as antidiabetic agents. Dietary polyphenols prevent and manage Type 2 diabetes mellitus via the insulin‐dependent approaches, for instance, protection of pancreatic islet β‐cell, reduction of β‐cell apoptosis, promotion of β‐cell proliferation, attenuation of oxidative stress, activation of insulin signaling, and stimulation of pancreas to secrete insulin, as well as…
Gnotobiotische untersuchungen an SPF-Mäusen im rahmen einer studie zur tumorentwicklung im kolon nach cholezystektomie
1985
Summary The relation between cholecystectomy and colon carcinogenesis has not been fully elucidated. As bacteria may be involved in the carcinogenic process, we investigated the effect of cholecystectomy and dimethylhydrazine (DMH) administration to SPF NMRI mice with regard to tumour genesis and bacterial colonisation of the intestine. It results from this study that cholecystectomy does not influence tumour genesis and that 6–7 months post operationem and DMH administration tumours and bacteria originally not found in the animals develop: Clostridia, eubacteria spec, which cannot be differentiated and E. lentum. Theses changes appear in group II of mice (laparotomy and DMH) and group III …
Effects of tributyltin(IV) chloride on fertilization ofStyela plicata(Ascidiacea: Tunicata): II. Scanning and transmission electron microscopy studies
2003
The morphological aspects of Styela plicata fertilization after treatment with tributyltin(IV) chloride are described by means of scanning and transmission electron microscopy investigations. Alterations have been shown both on female and male gametes; spermatozoa, all the egg envelopes and the mitochondria of the egg cortical cytoplasm are modified in relation to incubation time. As a consequence, the damage to gametes blocks sperm–egg interaction and fertilization does not occur. Copyright © 2003 John Wiley & Sons, Ltd.
