Change of individual BMI in Switzerland and the USA: a multilevel model for growth

Objective The aim is to analyze and compare individual BMI growth patterns of adults from Switzerland and the U.S. Methods The analyses are based on data from two population representative longitudinal household surveys, one from Switzerland, the other from the U.S. Each data set contains up to four data points for each adult individual. We use multilevel models for growth. Results It can be shown that growth patterns are different in different cohorts in the two countries: there are only small growth differences in the youngest and oldest, but large differences in the middle ages. The individual BMI increase of the middle age Swiss amounts to only half of that in the comparable U.S. individuals. Conclusion Given the much higher BMI level especially in the youngest cohort, this points to severe obesity problems in the U.S. middle aged population in the near future. A positive correlation between individual BMI level and growth may aggravate this fact.

Comparativa treball individual vs. treball de parella. Anàlisi a través de diferents tipologies de textos científics i preferències de l'alumnat

Els alumnes elaboren produccions de qualitat superior quan treballen en parelles que quan ho fan individualment. Sota aquesta màxima, l’estudi demostra que quan els alumnes escriuen textos científics descriptius, justificatius i descriptius-justificatius en parella milloren aspectes relacionats amb determinades habilitats inherents a qualsevol tipus de text, com l’estructuració de la informació i l’adequació del llenguatge al context, i d’altres específiques de textos descriptius i justificatius. És sorprenent constatar que aquesta millora es dóna en tot tipus d’alumnes, tant aquells amb hàbits d’estudi superiors com aquells amb dificultats d’aprenentatge, i que els avantatges d’aquesta metodologia de treball no es circumscriuen tan sols a l’àmbit acadèmic; els alumnes prefereixen treballar en parella perquè els permet compartir punts de vista i ajudar-se mútuament. Per tant, els resultats demostren que complementar les classes de ciències amb el treball en parella possibilita assolir amb més garanties l’aprenentatge significatiu dels nostres alumnes.

Cyberhealth serving to support individual intake of medication.

The Internet and new communication technologies are deeply affecting healthcare systems and the provision of care. The purpose of this article is to evaluate the possibility that cyberhealth, via the development of widespread easy access to wireless personal computers, tablets and smartphones, can effectively influence intake of medication and long-term medication adherence, which is a complex, difficult and dynamic behaviour to adopt and to sustain over time. Because of its novelty, the impact of cyberhealth on drug intake has not yet been well explored. Initial results have provided some evidence, but more research is needed to determine the impact of cyberhealth resources on long-term adherence and health outcomes, its user-friendliness and its adequacy in meeting e-patient needs. The purpose of such Internet-based interventions, which provide different levels of customisation, is not to take over the roles of healthcare providers; on the contrary, cyberhealth platforms should reinforce the alliance between healthcare providers and patients by filling time-gaps between visits and allowing patients to upload and/or share feedback material to be used during the visits. This shift, however, is not easily endorsed by healthcare providers, who must master new eHealth skills, but healthcare systems have a unique opportunity to invest in the Internet and to use this powerful tool to design the future of integrated care. Before this can occur, however, important issues must be addressed and resolved, for example ethical considerations, the scientific quality of programmes, reimbursement of activity, data security and the ownership of uploaded data.

Active solubilization and refolding of stable protein aggregates by cooperative unfolding action of individual hsp70 chaperones.

Hsp70 is a central molecular chaperone that passively prevents protein aggregation and uses the energy of ATP hydrolysis to solubilize, translocate, and mediate the proper refolding of proteins in the cell. Yet, the molecular mechanism by which the active Hsp70 chaperone functions are achieved remains unclear. Here, we show that the bacterial Hsp70 (DnaK) can actively unfold misfolded structures in aggregated polypeptides, leading to gradual disaggregation. We found that the specific unfolding and disaggregation activities of individual DnaK molecules were optimal for large aggregates but dramatically decreased for small aggregates. The active unfolding of the smallest aggregates, leading to proper global refolding, required the cooperative action of several DnaK molecules per misfolded polypeptide. This finding suggests that the unique ATP-fueled locking/unlocking mechanism of the Hsp70 chaperones can recruit random chaperone motions to locally unfold misfolded structures and gradually disentangle stable aggregates into refoldable proteins.

Feature Extraction from Whole-Sky Ground-Based Images for Cloud-Type Recognition

Several features that can be extracted from digital images of the sky and that can be useful for cloud-type classification of such images are presented. Some features are statistical measurements of image texture, some are based on the Fourier transform of the image and, finally, others are computed from the image where cloudy pixels are distinguished from clear-sky pixels. The use of the most suitable features in an automatic classification algorithm is also shown and discussed. Both the features and the classifier are developed over images taken by two different camera devices, namely, a total sky imager (TSI) and a whole sky imager (WSC), which are placed in two different areas of the world (Toowoomba, Australia; and Girona, Spain, respectively). The performance of the classifier is assessed by comparing its image classification with an a priori classification carried out by visual inspection of more than 200 images from each camera. The index of agreement is 76% when five different sky conditions are considered: clear, low cumuliform clouds, stratiform clouds (overcast), cirriform clouds, and mottled clouds (altocumulus, cirrocumulus). Discussion on the future directions of this research is also presented, regarding both the use of other features and the use of other classification techniques

Large TCR diversity of virus-specific CD8 T cells provides the mechanistic basis for massive TCR renewal after antigen exposure.

Ex vivo analysis of virus-specific CD8 T cell populations by anchored PCR has shown that the CD8 TCR repertoire was less oligoclonal (seven to nine clonotypes per individual epitope) than previously thought. In the current study, TCR diversity was investigated by assessing both the overall TCR β-chain variable regions usage as well as the CDR3 regions in ex vivo-isolated CMV- and EBV-specific CD8 T cells from 27 healthy donors. The average number of clonotypes specific to most single viral epitopes comprised between 14 and 77. Changes in the CD8 TCR repertoire were also longitudinally assessed under conditions of HIV-1 chronic infection (i.e., in patients with suppressed virus replication and after treatment interruption and Ag re-exposure). The results showed that a large renewal (≤80%) of the TRB repertoire occurred after Ag re-exposure and was eventually associated with an increased T cell recognition functional avidity. These results demonstrate that the global CD8 TCR repertoire is much more diverse (≤9-fold) than previously estimated and provide the mechanistic basis for supporting massive repertoire renewal during chronic virus infection and Ag re-exposure.

Les influències dels factors socials en l'ús de serveis formals

Objectiu: Aquest estudi pretén aportar coneixement sobre el model d’atenció que reben les persones de més de 79 anys dependents del municipi de Vic. Analitzar en quina mesura es fa ús dels serveis formals i quines variables influeixen en la utilització d’aquest. Mètode: Estudi retrospectiu, descriptiu i transversal. De metodologia quantitativa. La població d’estudi són aquelles persones de 80 i més anys de Vic que van sol·licitar la valoració de dependència entre els anys 2007-2010, amb un grau II o III de dependència reconegut i un Pla Individual d’Atenció validat i concedit per la Generalitat de Catalunya (n=453). Les dades provenen de registres de la Generalitat de Catalunya i de l’Àrea d’Afers Socials i Ciutadania de l’Ajuntament de Vic. Les variables dependents són la utilització de recursos formals (teleassitència, servei d’atenció domiciliària –públic i privat- , centre de dia, residència i prestacions econòmiques derivades de la llei de la dependència). El grau de dependència, el gènere, l’edat, l’estat civil, la convivència, el cuidador principal i el nivell de renda es van considerar variables independents. Resultats: El model d’atenció majoritari és el que complementa el suport informal amb el formal (62.3%). L’ús de recursos formals té un paper subsidiari (37.7%). La variable convivència influeix de forma significativa amb l’ús de serveis formals (p&0.001 en l’ús de TAS, el SAD públic i el SAD privat) . Conclusió: Els disseny de programes i criteris de provisió de serveis haurien de contemplar no només el grau de dependència sinó també variables més d’entorn com la convivència. No obstant, existeix encara poca evidència científica en aquesta línia, per això s’hauria de potenciar l’ investigació que permetés analitzar les variables de la funció social de forma més acurada. Paraules clau: Dependència, suport formal, suport informal.

Generation of short-term murine natural killer cell clones to analyze Ly49 gene expression.

Natural killer (NK) cellsexpress receptors specific for class I major histocompatibility complex (MHC) molecules. In the mouse, the class I specific receptors identified to date belong to the polymorphic Ly49 receptor family. Engagement of Ly49 receptors with their respective MHC ligands results in negative regulation of NK cell effector functions, consistent with a critical role of these receptors in "missing self" recognition. The Ly49 receptors analyzed so far are clonally distributed such that multiple distinct Ly49 receptors can be expressed by individual NK cells (for review see refs. 1-3). The finding that most NK cells that express the Ly49A receptor do so from a single Ly49A allele (whereby expression can occur from the maternal or the paternal chromosome) may thus reflect a putative receptor distribution process that restricts the number of Ly49 receptors expressed in a single NK cell (3-5).

The biochemistry of drug metabolism : an introduction : part 6, Inter-individual factors affecting drug metabolism.

This review is part of a series of review articles on the metabolism of drugs and other xenobiotics published in Chemistry & Biodiversity. After a thorough discussion of metabolic reactions and their enzymes, this article focuses on genetically determined differences in drug and xenobiotic metabolism. After a short introduction on the causes for genetic differences, the first focus is on species differences in drug and xenobiotic metabolism. A major chapter is then dedicated to clinically relevant genetic polymorphisms in human drug metabolism and resultant ethnic differences. The last two chapters deal with sex-dependent differences in drug metabolism and personalized pharmacotherapy related to inter-individual differences in drug metabolism.
