Evolution of Early Metazoa: Phylogenetic Status of the Hexactinellida Within the Phylum of Porifera (Sponges)

1998

The evolution of the Metazoa from their protozoan ancestors is one of the greatest puzzles of phylogeny (Willmer 1994; Cavalier-Smith et al. 1996). The emergence of multicellular animals has been explained by two major theories: the syncytial theory (Hadzi 1963) - origin from a multinucleated ciliate - and the colonial theory (Haeckel 1868) - origin from a colonial flagellate - both of which assume a di(poly)phyletic origin of the Metazoa. Numerous attempts to resolve whether the Metazoa are of mono- or polyphyletic origin have sought evidence from a wide variety of developmental and morphological data such as body symmetry, type of development (protostome vs. deuterostome), type of body ca…

Hyaluronic acid and its derivatives in drug delivery and imaging: Recent advances and challenges.

2015

Hyaluronic acid (HA) is a biodegradable, biocompatible, nontoxic, and non-immunogenic glycosaminoglycan used for various biomedical applications. The interaction of HA with the CD44 receptor, whose expression is elevated on the surface of many types of tumor cells, makes this polymer a promising candidate for intracellular delivery of imaging and anticancer agents exploiting a receptor-mediated active targeting strategy. Therefore, HA and its derivatives have been most investigated for the development of several carrier systems intended for cancer diagnosis and therapy. Nonetheless, different and important delivery applications of the polysaccharide have also been described, including gene …

La negatividad de Kant a Hegel: juicio estético y lenguaje especulativo”.

2017

Este artículo presenta una interpretación de la proposición especulativa de Hegel que, subrayando el “contragolpe” que el sujeto heredado de la tradición moderna sufre en ella, permite vincular el movimiento del sujeto hegeliano a la negatividad reconocida por Kant en el fondo de la capacidad de juzgar a propósito de la dimensión estética. De este modo se pretende, en primer lugar, cuestionar la lectura que ve en Hegel un retroceso respecto a la conciencia ganada por Kant en relación a la finitud o a la fisura constitutiva del sujeto moderno, y, en última instancia, en sintonía con relecturas recientes de Hegel como las de Žižek y Malabou, contribuir al cuestionamiento de la interpretación …

Paul Ricoeur's Surprising Take on Recognition

2011

This essay examines Paul Ricœur’s views on recognition in his book The Course of Recognition. It highlights those aspects that are in some sense surprising, in relation to his previous publications and the general debates on Hegelian Anerkennung and the politics of recognition. After an overview of Ricœur’s book, the paper examines the meaning of “recognition” in Ricœur’s own proposal, in the dictionaries Ricœur uses, and in the contemporary debates. Then it takes a closer look at the ideas of recognition as identification and as “taking as true.” Then it turns to recognition (attestation) of oneself, in light of the distinction between human constants (and the question “What am I?”), and h…

Identification of picobirnavirus from faeces of Italian children suffering from acute diarrhea

1996

Polyacrylamide gel electrophoresis of nucleic acid extracted from stool samples of diarrhoeic children revealed in 3 out of 690 (0.43 %) specimens two electrophoretic bands with a migration pattern characteristic of picobirnavirus ds-RNA. In none of the 92 control children were similar bands detected. No other potential enteric pathogens were found in the patients with picobirnavirus infection.

Expression and purification of polyhistidine-tagged rotavirus NSP4 proteins in insect cells

2003

The rotavirus nonstructural NSP4 protein, a transmembrane endoplasmic reticulum-specific glycoprotein, has been described as the first viral enterotoxin. Purified NSP4 or a peptide corresponding to NSP4 residues 114-135 induces diarrhea in young mice. NSP4 has a membrane-destabilizing activity and causes an increase in intracellular calcium levels and chloride secretion by a calcium-dependent signalling pathway in eucaryotic cells. In this study, four recombinant baculoviruses were generated expressing the rotavirus NSP4 glycoprotein from the human strains Wa and Ito, the porcine strain OSU, and the simian strain SA11, which belong to two different NSP4 genotypes, A and B. The recombinant g…
