A Combined Experimental and Computational Study of Chrysanthemin as a Pigment for Dye-Sensitized Solar Cells.

The theoretical study of chrysanthemin (cyanidin 3-glucoside) as a pigment for TiO-based dye-sensitized solar cells (DSSCs) was performed with the GAUSSSIAN 09 simulation. The electronic spectra of neutral and anionic chrysanthemin molecules were calculated by density functional theory with B3LYP functional and DGDZVP basis set. A better energy level alignment was found for partially deprotonated molecules of chrysanthemin, with the excited photoelectron having enough energy in order to be transferred to the conduction band of TiO semiconductor in DSSCs.

[Hematologic and immunologic signs of lupus: the experience of the hospital of Dakar].

Introduction: The systemic erythematosus lupus (SEL) or lupic disease is a systemic auto-immune pathology, characterized primarily by the presence of antibodies directed against native antibodies anti-DNA. The circumstances of discovery are variable and polymorphic. The hematologic signs and the immunological disorders constitute criteria of diagnosis of lupic disease.

Body composition predicted from skinfolds in African women: a cross-validation study using air-displacement plethysmography and a black-specific equation.

Skinfold thickness (SF) measurements are commonly used for the indirect assessment of body composition. It is necessary to know how large the bias is when using Caucasian SF-based prediction equations Africans, as no specific equations exist. Our first aim was to test the validity of the equation of Durnin & Womersley for predicting body density from SF in Africans.

Validity of impedance-based equations for the prediction of total body water as measured by deuterium dilution in African women.

Background: Little information is available on the validity of simple and indirect body-composition methods in non-Western populations. Equations for predicting body composition are population-specific, and body composition differs between blacks and whites.

Objective: We tested the hypothesis that the validity of equations for predicting total body water (TBW) from bioelectrical impedance analysis measurements is likely to depend on the racial background of the group from which the equations were derived.
