BACKGROUND: the impact of sarcopenia on quality of life is currently assessed by generic tools. However, these tools may not detect subtle effects of this specific condition on quality of life. OBJECTIVE: the aim of this study was to develop a sarcopenia-specific quality of life questionnaire (SarQoL, Sarcopenia Quality of Life) designed for community-dwelling elderly subjects aged 65 years and older. SETTINGS: participants were recruited in an outpatient clinic in Liège, Belgium. SUBJECTS: sarcopenic subjects aged 65 years or older. METHODS: the study was articulated in the following four stages: (i) Item generation-based on literature review, sarcopenic subjects' opinion, experts' opinion, focus groups; (ii) Item reduction-based on sarcopenic subjects' and experts' preferences; (iii) Questionnaire generation-developed during an expert meeting; (iv) Pretest of the questionnaire-based on sarcopenic subjects' opinion. RESULTS: the final version of the questionnaire consists of 55 items translated into 22 questions rated on a 4-point Likert scale. These items are organised into seven domains of dysfunction: Physical and mental health, Locomotion, Body composition, Functionality, Activities of daily living, Leisure activities and Fears. In view of the pretest, the SarQoL is easy to complete, independently, in ∼10 min. CONCLUSIONS: the first version of the SarQoL, a specific quality of life questionnaire for sarcopenic subjects, has been developed and has been shown to be comprehensible by the target population. Investigations are now required to test the psychometric properties (internal consistency, test-retest reliability, divergent and convergent validity, discriminant validity, floor and ceiling effects) of this questionnaire.

Organic Rankine cycles are particularly well suited for recovering energy from low-grade heat sources, such as industrial waste, engine exhaust gas or solar concentrated power. In ow-capacity systems, volumetric expanders are often preferred to turbomachines because of their reliability, robustness, low rotational speed and their ability to handle high pressure ratios… Different types of machines have been investigated and successfully tested by the uthors and tools have been developed in order to analyse experimental data. Semi-empirical odel was built to analyse losses, detect potential improvement and simulate performances. This paper present a simple and fastcomputing semi-analytical model useful for simulate dynamic system integrating volumetric expander. This model is validated on experimental data and compare to black-box model. [less ▲]

Background: The absorptive and goblet cells are the main cellular types encountered in the intestine epithelium. The cell lineage Caco-2 is a model commonly used to reproduce the features of the bowel epithelium. However, there is a strong debate regarding the value of Caco-2 cell culture to mimick in vivo situation. Indeed, some authors report in Caco-2 a low paracellular permeability and an ease of access of highly diffusible small molecules to the microvilli, due to an almost complete lack of mucus. The HT29-5M21 intestinal cell lineage is a mucin-secreting cellular population. A co-culture system carried out in a serum-free medium and comprising both Caco-2 and HT29-5M21 cells was developed. The systematic use of a co-culture system requires the characterization of the monolayer under a given experimental procedure. Results: In this study, we investigated the activity and localization of the alkaline phosphatase and the expression of IAP and MUC5AC genes to determine a correlation between these markers and the cellular composition of a differentiated monolayer obtained from a mixture of Caco-2 and HT29-5M21 cells. We observed that the culture conditions used ( serum-free medium) did not change the phenotype of each cell type, and produced a reproducible model. The alkaline phosphatase expression characterizing Caco-2 cells was influenced by the presence of HT29-5M21 cells. Conclusion: The culture formed by 75% Caco-2 and 25% HT29-5M21 produce a monolayer containing the two main cell types of human intestinal epithelium and characterized by a reduced permeability to macromolecules.

A very simple, cheap and fast SERS method using functionalized silver nanoparticles was developed to detect bisphenols. This method was applied for the semi-quantitative detection of bisphenol A (BPA), bisphenol B (BPB) and bisphenol F (BPF) separately. Afterwards, a feasibility study of performing a multiplex SERS detection of BPA, BPB and BPF was successfully carried out. Finally, this developed method was applied on real samples which were solutions comprising cash receipts collected from different stores. [less ▲]

This seminar shows how modeling and simulation environments that are built using equation-based solvers can benefit the building energy community. Such modeling and simulation environments separate the formulation of a model’s underlying physics from its numerical solution algorithms. This allows input-output free modeling, it leads to faster model development time and it facilitates model reuse for different applications. Equation-based modeling and simulation environments are frequently used in various industrial sectors. For building energy simulation, however, they have not yet enjoyed wide-spread use. This seminar encourages discussions to understand their applicability, advantages and limitations for the building energy community. [less ▲]

The National Institute of Standards and Technology (NIST), in collaboration with the National Institutes of Health (NIH), has developed a Standard Reference Material (SRM) to support technology development in metabolomics research. SRM 1950 Metabolites in Human Plasma is intended to have metabolite concentrations that are representative of those found in adult human plasma. The plasma used in the preparation of SRM 1950 was collected from both male and female donors, and donor ethnicity targets were selected based upon the ethnic makeup of the U.S. population. Metabolomics research is diverse in terms of both instrumentation and scientific goals. This SRM was designed to apply broadly to the field, not towards specific applications. Therefore, concentrations of approximately 100 analytes, including amino acids, fatty acids, trace elements, vitamins, hormones, selenoproteins, clinical markers, and perfluorinated compounds (PFCs), were determined. Value assignment measurements were performed by NIST and the Centers for Disease Control and Prevention (CDC). SRM 1950 is the first reference material developed specifically for metabolomics research. [less ▲]

A unique statistical data analysis method has been developed for reducing nulling interferometry data. The idea is to make use of the statistical distributions of the fluctuating null depths and beam intensities to retrieve the astrophysical null depth in the presence of fluctuations. The approach yields an accuracy much better than is possible with standard data reduction methods, because the accuracy of the null depth is not limited by the sizes of the phase and intensity errors but by the uncertainties on their statistical distributions. The result is an improvement in the instrumental null depth measurement limit of roughly an order of magnitude. We show in this paper that broadband null depths of 10[SUP]-4[/SUP] can be measured in the lab with our infrared Fiber Nuller without achromatic phase shifters. On sky results are also dramatically improved, with measured contrasts up to a couple of 10[SUP]-4[/SUP] with our instrument mounted on the Hale telescope at the Palomar Observatory. This statistical analysis is not specific to our instrument and may be applicable to other interferometers. [less ▲]
