“Purpose To provide population norms for the Euro-QoL-5D (EQ-5D) according to age, sex, ethnicity BLZ945 in vitro and language version using a representative sample of adults aged 18 years and above in the Singapore population.
Methods A total of 5,594 respondents who completed the self-administrated paper-based
EQ-5D in the Singapore Mental Health Study were included in this study. Socio-demographic characteristics were captured using a structured questionnaire.
Results The mean age of the sample was 40 years, females comprised 52.2% of the sample and 78% were of Chinese descent. Pain/discomfort was the most frequently reported problem (15.3%) followed by anxiety/depression (8.2%), whilst self-care (0.5%) was the least frequently reported problem in the Singapore population. Multiple linear regression analysis revealed that younger age, higher income, those employed and those administered
English version of the questionnaire were significantly associated with higher EQ-5D index.
Conclusions This article provides important population norms for the EQ-5D for measuring health-related quality of life (HRQOL) both in clinical settings and in the research context. Our results GNS-1480 suggest that socio-demographic factors should be taken into account when assessing HRQOL among adults in Singapore.”
“A KU-57788 chemical structure modified cellulose material was prepared by grafting glycidyl methacrylate to cellulose (Cell-g-GMA) with subsequent functionalization with imidazole (Cell-g-GMA-imidazole). This latter compound was used in the adsorption of copper from aqueous solution.
The mechanism of Cu(II) binding onto the cell-g-GMA-imidazole was investigated at the molecular level using scanning electron microscopy (SEM), Fourier transform infrared (FTIR), x-ray photoelectron spectroscopy (XPS), energy dispersive x-ray analysis (EDX) and X-ray diffraction (XRD). FTIR and Raman spectroscopy provided an insight into the extent to which perturbation of the imidazole ring occurred following adsorption of the metal while XPS spectra indicated the binding of Cu(II) ions to nitrogen atoms by the appearance of additional binding energy peaks for nitrogen on the cellulose-g-GMA-imidazole sample post adsorption. The EDX technique provided clear evidence of the physical presence of both the copper and sulfate on the cellulose-g-GMA-imidazole material post adsorption. XRD analysis further confirmed the presence of a copper species in the adsorbent material as copper sulfate hydroxide (Cu(3)(OH)(4)SO(4) – antlerite).
