Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Effect of resistance training combined with aerobic exercise on aortic arterial stiffness in older adults: a secondary analysis of randomized controlled trial

open access: yesJournal of Physical Fitness and Sports Medicine, 2019
Aerobic exercise prior to resistance training is likely to have a preventive effect on arterial stiffening caused by resistance training alone. The purpose of this study was to examine, as secondary analysis, the effect of aerobic exercise before ...

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

open access: yesFEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

Full-scale performance assessment of aircraft secondary sandwich structure using thermoelastic stress analysis

open access: yes, 2009
The use of resin film infusion (RFI) has been proven to reduce the cost of production of aircraft secondary sandwich structure. In this paper thermoelastic stress analysis (TSA) is used to assess the performance of full scale aircraft sandwich structure ...

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Secondary analysis of qualitative interview data (in Germany) – problems and open issues of a new research strategy

open access: yesJournal für Psychologie, 2007
Qualitative data are a rich and often not fully exploited source of research material. Nonetheless they are seldom reanalysed. The analysis of a nationwide German survey of qualitative researchers shows that there are some concerns and open issues ...

Apories de la mise en banque : retour d’expérience sur la réutilisation d’enquêtes qualitatives

open access: yesTracés, 2019
Funding agencies and journal editors strongly incite researchers to share and archive their data, when they don’t compel them to do so. However, the ways we archive data have a strong influence on their potential for reuse.

Secondary Data Analysis of Epidemiology in Asia

open access: yesJournal of Epidemiology, 2014
It is widely acknowledged that there is great potential for utilizing databases in health care systems in developed countries.1 Modern health care databases have two characteristics that make them attractive to epidemiologists who work on ‘real-world’ problems: routinely conducted data collection and perpetual electronic data storage.
