Neck pain brought into focus.
A time honored dictum states that the eyes "lead the body", i.e., that the body typically adjusts its position to compensate for an impoverished retinal image (e.g., as due to optical blur, and/or inappropriately sized visual target). But only moderate or low level of evidence exists in support of this view. Inconclusive evidence does not, however, equal negative evidence. The accommodation/ver...
متن کاملEukaryotic aspects of translation initiation brought into focus.
In all organisms, mRNA-directed protein synthesis is catalysed by ribosomes. Although the basic aspects of translation are preserved in all kingdoms of life, important differences are found in the process of translation initiation, which is rate-limiting and the most important step for translation regulation. While great strides had been taken towards a complete structural understanding of the ...
متن کاملEvaluation of the different forces brought into play during tube foot activities in sea stars.
Sea star tube feet consist of an enlarged and flattened distal extremity (the disc), which makes contact with the substratum, and a proximal contractile cylinder (the stem), which acts as a tether. In this study, the different forces brought into play during tube foot functioning were investigated in two related species. The tube feet of Asterias rubens and Marthasterias glacialis attach to gla...
متن کاملSecurity control brought back to the user
The activity of the Ph.D. student Juri Luca De Coi involved the research field of policy languages and can be divided in three parts. The first part of the Ph.D. work investigated the state of the art in policy languages, ending up with ∙ identifying the requirements up-to-date policy languages have to fulfill ∙ defining a policy language able to fulfill such requirements (namely, the Protune p...
متن کاملThe hammerhead ribozyme structure brought in line.
RNA catalysis seems to be considerably more wide spread than originally thought, with the most prominent example being the ribosome, where RNA catalyses the peptidyl-transferase reaction. Among the most and longest studied catalytic RNAs are the small nucleolytic ribozymes, such as the hairpin, VS, HDV and hammerhead ribozymes. They all catalyse the site-specific cleavage of their own phosphodi...
