Introduction: Fragile X syndrome (FXS) is the most common inherited cause of intellectual disability. With no curative treatment available, current therapeutic approaches are aimed at symptom management. FXS is caused by silencing the FMR1 gene, which encodes FMRP; as loss of FMRP leads to the development of symptoms associated with FXS. Areas covered: In this evaluation, the authors examine the role of the metabotropic glutamate receptor 5 (mGluR5) in the pathophysiology of FXS, and its suitability as a target for rescuing the disease state. Furthermore, the authors review the evidence from preclinical studies of pharmacological interventions targeting mGluR5 in FXS. Lastly, the authors assess the findings from clinical studies in FXS, in particular the use of the Aberrant Behavior Checklist-Community Edition (ABC-C) and the recently developed ABC-C for FXS scale, as clinical endpoints to assess disease modification in this patient population. Expert opinion: There is cautious optimism for the successful treatment of the core behavioral and cognitive symptoms of FXS based on preclinical data in animal models and early studies in humans. However, the association between mGluR5-heightened responsiveness and the clinical phenotype in humans remains to be demonstrated. Many questions regarding the optimal treatment and outcome measures of FXS remain unanswered.

This paper shows how one of the developers of QWERTY continued to use the trade secret that underlay its development to seek further efficiency improvements after its introduction. It provides further evidence that this was the principle used to design QWERTY in the first place and adds further weight to arguments that QWERTY itself was a consequence of creative design and an integral part of a highly efficient system rather than an accident of history. This further serves to raise questions over QWERTY's forced servitude as 'paradigm case' of inferior standard in the path dependence literature. The paper also shows how complementarities in forms of intellectual property rights protection played integral roles in the development of QWERTY and the search for improvements on it, and also helped effectively conceal the source of the efficiency advantages that QWERTY helped deliver.

En aquest treball es tracten qüestions de la geometria integral clàssica a l'espai hiperbòlic i projectiu complex i a l'espai hermític estàndard, els anomenats espais de curvatura holomorfa constant. La geometria integral clàssica estudia, entre d'altres, l'expressió en termes geomètrics de la mesura de plans que tallen un domini convex fixat de l'espai euclidià. Aquesta expressió es dóna en termes de les integrals de curvatura mitja. Un dels resultats principals d'aquest treball expressa la mesura de plans complexos que tallen un domini fixat a l'espai hiperbòlic complex, en termes del que definim com volums intrínsecs hermítics, que generalitzen les integrals de curvatura mitja. Una altra de les preguntes que tracta la geometria integral clàssica és: donat un domini convex i l'espai de plans, com s'expressa la integral de la s-èssima integral de curvatura mitja del convex intersecció entre un pla i el convex fixat? A l'espai euclidià, a l'espai projectiu i hiperbòlic reals, aquesta integral correspon amb la s-èssima integral de curvatura mitja del convex inicial: se satisfà una propietat de reproductibitat, que no es té en els espais de curvatura holomorfa constant. En el treball donem l'expressió explícita de la integral de la curvatura mitja quan integrem sobre l'espai de plans complexos. L'expressem en termes de la integral de curvatura mitja del domini inicial i de la integral de la curvatura normal en una direcció especial: l'obtinguda en aplicar l'estructura complexa al vector normal. La motivació per estudiar els espais de curvatura holomorfa constant i, en particular, l'espai hiperbòlic complex, es troba en l'estudi del següent problema clàssic en geometria. Quin valor pren el quocient entre l'àrea i el perímetre per a successions de figures convexes del pla que creixen tendint a omplir-lo? Fins ara es coneixia el comportament d'aquest quocient en els espais de curvatura seccional negativa i que a l'espai hiperbòlic real les fites obtingudes són òptimes. Aquí provem que a l'espai hiperbòlic complex, les cotes generals no són òptimes i optimitzem la superior.

This study aims at evaluating how minor and serious delinquency relates to cognitive and emotional functioning in high-risk adolescents, taking problematic substance use into account. In 80 high-risk adolescent males (13-19 years), the frequency of minor and serious offences committed over the last year was predicted, in multiple regression analyses, from problematic substance use, intellectual efficiency, trait impulsivity, alexithymia (inability to express feelings in words), and cognitive coping strategies. Both minor and serious delinquency were more frequent in adolescents with more problematic substance use and higher intellectual efficacy. Minor delinquency was further related to a tendency to act out when experiencing negative emotions, and difficulties in focusing energy on instrumental action when under stress; while serious delinquency was predominantly and strongly related to rigid and dichotomous thinking. The results underline the heterogeneous nature of delinquency, minor offences being primarily associated with emotional regulation deficits, while major offences are related with a lack of cognitive flexibility.

Treball de recerca realitzat per una alumna d'ensenyament secundari i guardonat amb un Premi CIRIT per fomentar l'esperit científic del Jovent l'any 2009. El present treball és un estudi de la personalitat humana, literària i filosòfica de Jaume Brossa així com un anàlisi del medi sociohistòric que li va tocar viure. El mètode utilitzat ha estat, en primer lloc, un rastreig de material original, articles publicats entre els anys 1892 i 1902 en diversos òrgans de premsa de Barcelona i Madrid. Una vegada obtingut el material requerit, s’ha sondejat per dins de les seves línies fins a trobar quin era el seu pensament en molts aspectes, a saber: el seu posicionament entorn els grans centres d’atenció del seu temps: el nacionalisme, el moviment obrer, l’estètica modernista en les seves parcel•les de música, literatura, teatre etc., tots aquests camps, tractats des de la base de la seva actitud regeneracionista i revolucionària. L’estudi s’ha realitzat des d’un enfocament crític: intentar esbrinar quines han estat les causes per les quals un autor certament notable de les nostres lletres ha estat marginat o, si més no, minimitzat en el seu abast intel•lectual. I, tal com es planteja al començament del treball, aquest consta d’una recerca de causes, implicacions, contextos etc. que ens permetin esbrinar per què Jaume Brossa ha estat desacreditat.

OBJECTIVE: Ability to work and live independently is of particular concern for patients with Parkinson's disease (PD). We studied a series of PD patients able to work or live independently at baseline, and evaluated potential risk factors for two separate outcomes: loss of ability to work and loss of ability to live independently. METHODS: The series comprised 495 PD patients followed prospectively. Ability to work and ability to live independently were based on clinical interview and examination. Cox regression models adjusted for age and disease duration were used to evaluate associations of baseline characteristics with loss of ability to work and loss of ability to live independently. RESULTS: Higher UPDRS dyskinesia score, UPDRS instability score, UPDRS total score, Hoehn and Yahr stage, and presence of intellectual impairment at baseline were all associated with increased risk of future loss of ability to work and loss of ability to live independently (P ≤ 0.0033). Five years after initial visit, for patients ≤70 years of age with a disease duration ≤4 years at initial visit, 88% were still able to work and 90% to live independently. These estimates worsened as age and disease duration at initial visit increased; for patients >70 years of age with a disease duration >4 years, estimates at 5 years were 43% able to work and 57% able to live independently. CONCLUSIONS: The information provided in this study can offer useful information for PD patients in preparing for future ability to perform activities of daily living.

ISAFRUIT is an integrated European Union Project focussed on increasing fruit consumption as a means to improve human health, through evaluating the fruit chain and addressing bottlenecks therein.The innovations which are being developed throughout the ISAFRUIT Project have been analysed to determine both the success factors and the obstacles in reaching the commercialisation stage. Only 9.58% of the deliverables planned within the Project were focussed on developing technological innovations.There is evidence, however, of successes in the development of new innovations arising from the ISAFRUIT Project, with several other potential innovations in the pipeline. Of the technologies identified, 67% are still at the “invention stage”; that is, the stage prior to bridging the so-called “valley of death”, the stage between an invention and an innovation. Those which are considered to have moved over the “valley of death” either had industry partners included in the Project, or had consulted with industry to ensure that the technology was relevant, or met a recognised industry need. Many of the technologies which made less progress did not have the same interactions with industry. A number of other issues were identified which prevented further progress towards innovation. The need for scientists to publish scientific papers, both for their career pathways and to increase their chances of future funding, was identified as one issue, although the filing of patents is now becoming more accepted and recognised. The patenting system is considered complex by many scientists and is not well-understood. Finally, agreements between partners on the sharing of intellectual property rights can cause a delay in the innovation process.

La qualitat de vida s’està convertint en un concepte clau i unificador en l’atenció i educació de les persones amb discapacitat intel•lectual. Així mateix, la percepció actual sobre les persones amb discapacitat ha canviat substancialment. En el moment actual, cal plantejar-se quines són les aplicacions i les implicacions que tenen per l’atenció i educació de les persones amb discapacitat intel•lectual els principis derivats del nou concepte de discapacitat i de la qualitat de vida. Aquesta investigació pretén essencialment elaborar un conjunt d’instruments que permetin avaluar la qualitat de les pràctiques educatives dels centres d’educació especial. Amb aquest objectiu s’ha seguit un procediment estructurat i ordenat en l’elaboració dels instruments com en la seva valoració inicial. Per avaluar la qualitat dels centres d’educació especial es proposen una sèrie qüestionaris tant pels professionals, les famílies i els alumnes. Els resultats indiquen que el conjunt d’instruments d’avaluació permeten recollir informació àmplia i variada de les pràctiques d’un centre d’educació especial, determinar les seves fortaleses i debilitats i servir de base per establir plans de millora estretament relacionats amb el context particular del centre i amb el que es considera una bona pràctica educativa.

Business cycle theory is normally described as having evolved out of a previous tradition of writers focusing exclusively on crises. In this account, the turning point is seen as residing in Clément Juglar's contribution on commercial crises and their periodicity. It is well known that the champion of this view is Schumpeter, who propagated it on several occasions. The same author, however, pointed to a number of other writers who, before and at the same time as Juglar, stressed one or another of the aspects for which Juglar is credited primacy, including the recognition of periodicity and the identification of endogenous elements enabling the recognition of crises as a self-generating phenomenon. There is indeed a vast literature, both primary and secondary, relating to the debates on crises and fluctuations around the middle of the nineteenth century, from which it is apparent that Juglar's book Des Crises Commerciales et de leur Retour Périodique en France, en Angleterre et aux États-Unis (originally published in 1862 and very much revised and enlarged in 1889) did not come out of the blue but was one of the products of an intellectual climate inducing the thinking of crises not as unrelated events but as part of a more complex phenomenon consisting of recurring crises related to the development of the commercial world - an interpretation corroborated by the almost regular occurrence of crises at about 10-year intervals.

Curated databases are an integral part of the tool set that researchers use on a daily basis for their work. For most users, however, how databases are maintained, and by whom, is rather obscure. The International Society for Biocuration (ISB) represents biocurators, software engineers, developers and researchers with an interest in biocuration. Its goals include fostering communication between biocurators, promoting and describing their work, and highlighting the added value of biocuration to the world. The ISB recently conducted a survey of biocurators to better understand their educational and scientific backgrounds, their motivations for choosing a curatorial job and their career goals. The results are reported here. From the responses received, it is evident that biocuration is performed by highly trained scientists and perceived to be a stimulating career, offering both intellectual challenges and the satisfaction of performing work essential to the modern scientific community. It is also apparent that the ISB has at least a dual role to play to facilitate biocurators' work: (i) to promote biocuration as a career within the greater scientific community; (ii) to aid the development of resources for biomedical research through promotion of nomenclature and data-sharing standards that will allow interconnection of biological databases and better exploit the pivotal contributions that biocurators are making.

La publicación de los códigos penales en el estado de Zheng de la época de las Primaveras y Otoños de China, concretamente en el año 536 a. C., marcó el comienzo del movimiento intelectual denominado Mingjia, que los historiógrafos de la dinastía Han equipararon en importancia con la de otras escuelas de pensamiento de la misma época tales como el Confucianismo y el Taoísmo. Sus miembros eran destacados activistas políticos y sociales y al mismo tiempo se dedicaban al estudio de los nombres conceptuales. Estos dos tipos de actividades no eran incompatibles, sino mutuamente complementarias para estos filósofos elocuentes, quienes contribuyeron especialmente al estudio de Xingming y a las teorías lógicas de la antigua China.
