Evolució de les persones 4a i 5a del Present d'Indicatiu de la 1a conjugació : Sincretisme amb el Subjuntiu i l'Imperatiu

L'objectiu bàsic del TFC és aprofundir en l'estudi diacrònic des del llatí al català del canvi de les desinències -am/au del Present d'Indicatiu de la 1a conjugació a -em/eu en la major part del català. L'estudi té dues parts diferenciades. Una primera part dóna compte de l'evolució etimològica d'aquestes formes del Present d'Indicatiu fins a l'època del català medieval. I una segona part, que és la central, estudia el procés mitjançant el qual aquestes formes arizotòniques del Present d'Indicatiu de la 1a conjugació han convergit amb el Present de Subjuntiu i l'Imperatiu en la major part del territori de parla catalana.

Interlinkages and forecasting made possible by the use of the DECOIN analytical tool kit

This technical report is a document prepared as a deliverable [D4.3 Report of the Interlinkages and forecasting prototype tool] of a EU project – DECOIN Project No. 044428 - FP6-2005-SSP-5A. The text is divided into 4 sections: (1) this short introductory section explains the purpose of the report; (2) the second section provides a general discussion of a systemic problem found in existing quantitative analysis of sustainability. It addresses the epistemological implications of complexity, which entails the need of dealing with the existence of Multiple-Scales and non-equivalent narratives (multiple dimensions/attributes) to be used to define sustainability issues. There is an unavoidable tension between a “steady-state view” (= the perception of what is going on now – reflecting a PAST --& PRESENT view of the reality) versus an “evolutionary view” (= the unknown transformation that we have to expect in the process of becoming of the observed reality and in the observer – reflecting a PRESENT --& FUTURE view of the reality). The section ends by listing the implications of these points on the choice of integrated packages of sustainability indicators; (3) the third section illustrates the potentiality of the DECOIN toolkit for the study of sustainability trade-offs and linkages across indicators using quantitative examples taken from cases study of another EU project (SMILE). In particular, this section starts by addressing the existence of internal constraints to sustainability (economic versus social aspects). The narrative chosen for this discussion focuses on the dark side of ageing and immigration on the economic viability of social systems. Then the section continues by exploring external constraints to sustainability (economic development vs the environment). The narrative chosen for this discussion focuses on the dark side of current strategy of economic development based on externalization and the “bubbles-disease”; (4) the last section presents a critical appraisal of the quality of energy data found in energy statistics. It starts with a discussion of the general goal of statistical accounting. Then it introduces the concept of multipurpose grammars. The second part uses the experience made in the activities of the DECOIN project to answer the question: how useful are EUROSTAT energy statistics? The answer starts with an analysis of basic epistemological problems associated with accounting of energy. This discussion leads to the acknowledgment of an important epistemological problem: the unavoidable bifurcations in the mechanism of accounting needed to generate energy statistics. By using numerical example the text deals with the following issues: (i) the pitfalls of the actual system of accounting in energy statistics; (ii) a critical appraisal of the actual system of accounting in BP statistics; (iii) a critical appraisal of the actual system of accounting in Eurostat statistics. The section ends by proposing an innovative method to represent energy statistics which can result more useful for those willing develop sustainability indicators.

Acute Damage to the Posterior Limb of the Internal Capsule on Diffusion Tensor Tractography as an Early Imaging Predictor of Motor Outcome after Stroke

Background and Purpose Early prediction of motor outcome is of interest in stroke management. We aimed to determine whether lesion location at DTT is predictive of motor outcome after acute stroke and whether this information improves the predictive accuracy of the clinical scores. Methods We evaluated 60 consecutive patients within 12 hours of MCA stroke onset. We used DTT to evaluate CST involvement in the MC and PMC, CS, CR, and PLIC and in combinations of these regions at admission, at day 3, and at day 30. Severity of limb weakness was assessed using the m-NIHSS (5a, 5b, 6a, 6b). We calculated volumes of infarct and FA values in the CST of the pons. Results Acute damage to the PLIC was the best predictor associated with poor motor outcome, axonal damage, and clinical severity at admission (P&.001). There was no significant correlation between acute infarct volume and motor outcome at day 90 (P=.176, r=0.485). The sensitivity, specificity, and positive and negative predictive values of acute CST involvement at the level of the PLIC for 4 motor outcome at day 90 were 73.7%, 100%, 100%, and 89.1%, respectively. In the acute stage, DTT predicted motor outcome at day 90 better than the clinical scores (R2=75.50, F=80.09, P&.001). Conclusions In the acute setting, DTT is promising for stroke mapping to predict motor outcome. Acute CST damage at the level of the PLIC is a significant predictor of unfavorable motor outcome.

Tetrahydrobenzo[h][1,6]naphthyridine-6-chlorotacrine hybrids as a new family of anti-Alzheimer agents targeting beta-amyloid, tau, and cholinesterase pathologies

Optimization of an essentially inactive 3,4-dihydro-2H-pyrano[3,2-c]quinoline carboxylic ester derivative as acetylcholinesterase (AChE) peripheral anionic site (PAS)-binding motif by double O → NH bioisosteric replacement, combined with molecular hybridization with the AChE catalytic anionic site (CAS) inhibitor 6-chlorotacrine and molecular dynamics-driven optimization of the length of the linker has resulted in the development of the trimethylene-linked 1,2,3,4-tetrahydrobenzo[h][1,6]naphthyridine6-chlorotacrine hybrid 5a as a picomolar inhibitor of human AChE (hAChE). The tetra-, penta-, and octamethylene-linked homologues 5bd have been also synthesized for comparison purposes, and found to retain the nanomolar hAChE inhibitory potency of the parent 6-chlorotacrine. Further biological profiling of hybrids 5ad has shown that they are also potent inhibitors of human butyrylcholinesterase and moderately potent Aβ42 and tau anti-aggregating agents, with IC50 values in the submicromolar and low micromolar range, respectively. Also, in vitro studies using an artificial membrane model have predicted a good brain permeability for hybrids 5ad, and hence, their ability to reach their targets in the central nervous system. The multitarget profile of the novel hybrids makes them promising leads for developing anti-Alzheimer drug candidates with more balanced biological activities.

Estudi sobre el consum de tabac en dones hospitalitzades i intervencions per deixar de fumar a l’àrea de Maternitat de l’Hospital de la Vall d’Hebron.

Introducció: El consum de tabac és la principal causa de morbiditat i mortalitat prematura en els països desenvolupats. Els pacients hospitalitzats constitueixen una població diana d’intervencions que faciliten l’abandonament del tabac. De fet, les intervencions realitzades pels professionals sanitaris durant el període d’hospitalització que inclouen un mes de seguiment han demostrat la seva eficàcia. Objectius: Analitzar la prevalença del consum de tabac entre les dones ingressades a l’àrea de maternitat de l’Hospital de la Vall d’Hebron. A més, pretén conèixer els serveis d’atenció al fumador que ofereix el centre i el compliment de la legislació vigent que regula el consum de tabac als hospitals d’aguts a Espanya. Material i Mètodes: Estudi quantitatiu, descriptiu i transversal. La recollida de dades es va dur a terme a través d’entrevistes realitzades a les pacients ingressades entre el mes de novembre i desembre del 2014. Aquestes pacients van ser seleccionades a través d’un mostreig aleatori, simple i probabilístic. Es van analitzar les següents variables: les dades sociodemogràfiques, el patró de consum habitual i durant l’ingrés hospitalari, els exfumadors, la cooximetria, el coneixement i el compliment de la normativa per a tots els fumadors i no fumadors i el grau en què es duen a terme les intervencions infermeres (5A: Ask, Advice, Assess, Assist, Arrange). Resultats: De les 35 pacients que van ser entrevistades només 4 dones eren fumadores (11,4%), 9 eren exfumadores i 22 no havien fumat mai. Només a 4 pacients se’ls havia explicat en què consistia la normativa del centre, no obstant, un 100% ja la coneixien. El grau d’intervencions d’infermeria realitzades d’acord amb les 5A va ser molt baix, ja que de les 4 pacients fumadores només a un 50% se’ls hi va preguntar si fumaven. Conclusions: La prevalença del consum de tabac en les dones que es troben ingressades a l’àrea de maternitat és baixa i és inferior (12,5%) a la de la població general (27,1%). Es presenta un alt grau de coneixement de la normativa vigent del centre, ja que el 100% de les pacients entrevistades saben en què consisteix. Fent referència al nivell d’intervencions per deixar de fumar d’acord amb les 5A és molt baixa, sobretot si les comparem amb altres països.
