Characterization of cytotoxic ribonucleases: from the internalization pathway to the importance of dimeric structures

En aquesta tesi s'ha caracteritzat la ruta d'internalització de l'onconasa, una RNasa citotòxica. Els resultats indiquen que l'onconasa entra a les cèl·lules per la via dependent de clatrina i del complex AP-2. Seguidament es dirigeix als endosomes de reciclatge i es a través d'aquesta ruta que la proteïna exerceix la citotoxicitat. Per altra banda, els resultats d'aquest treball demostren que PE5, una variant citotòxica de la ribonucleasa pancreàtica humana (HP-RNasa), interacciona amb la importina  mitjançant diferents residus que tot i que no són seqüencials, es troben propers en l'estructura tridimensional d'aquesta proteïna. PM8 és una HP-RNasa amb estructura cristal·logràfica dimèrica constituïda per intercanvi de dominis N-terminals. En aquesta tesi s'han establert les condicions per estabilitzar aquest dimer en solució i també es proposa un mecanisme per la dimerització.

Rethinking Polycentric Structures in the Postcolonial Church: Dangers of “Drone Missiology” or Afghanization of Christianity

In this brief essay I shall obviously draw from my reflections which I shared over the past three decades and to which I have provided some bibliographical references. It is clear from them that I had several opportunities to share my views beyond the Anglo-Saxon world, and some of them in events organized by K. Koschorke himself in the German academic circles as Munich-Freising Conferences. It is important that we do not get misled by words. We also need clarity of the concepts involved. Koschorke’s emphasis on “ploycentric structures” requires to be discussed and analysed critically to sort out its geographic components and its political-cultural implications, in order to be clear where lie the priorities. Without such exercise we will run the risk of hiding behind the ambiguity of words and concepts. My gut feelings make me believe that “polycentric structures” is just what the West needs in the postcolonial era to replace the control it has lost with decolonization.

A study of the TAGS, an enduring teaching tool: teachers’ perspectives on the Teacher Assessment of Grammatical Structures teaching practices and application

This paper is studied look at the Teacher’s Assessment of Grammatical Structures (TAGS), Teacher Assessment of Spoken Language (TASL), and Cottage Acquisition Scales for Listening, Language and Speech (CASLLS) criterion-referenced language assessments as well as an inquiry into how teachers of the deaf use the TAGS currently as a teaching tool.
