Association of Microvasculature Changes with Visual Outcomes in Idiopathic Epiretinal Membrane Surgery: A Clinical Trial.

The purpose of this paper is to evaluate macular microvascular changes and their correlation with visual outcomes after idiopathic epiretinal membrane (iERM) surgery. Forty-seven eyes operated for iERM were included in this retrospective case series. The foveal avascular zone (FAZ) area, and the vessel density (VD) in the superficial and the deep capillary plexus (SCP and DCP) were evaluated using optical coherence tomography angiography (OCTA).

Surface spectroscopy of adsorbed proteins: input of data treatment by principal component analysis.

X-ray photoelectron spectroscopy (XPS) and time-of-flight secondary ion mass spectroscopy (ToF-SIMS), two surface-sensitive spectroscopic methods, are commonly used to characterize adsorbed protein layers. Principal component analysis (PCA) is a statistical method which aims at reducing the number of variables in complex sets of data while retaining most of the original information. The aim of this paper is to review work carried out in our group regarding the use of PCA with a view to facilitate and deepen the interpretation of ToF-SIMS or XPS spectra acquired on adsorbed protein layers.

Socio-spatial disparities of obesity among adults in the urban setting of Ouagadougou, Burkina Faso.

Objectives: To document the prevalence and the socio-spatial variations of obesity and to identify individual and household characteristics, lifestyles and dietary practices contributing to obesity and its socio-spatial distribution.

Design: Population-based cross-sectional survey. We selected 1,570 households from four strata characterised as unstructured and low building-density (ULBD), unstructured and high building-density (UHBD), structured and low building-density (SLBD) and structured and high building-density (SHBD) areas.

Surface analysis of an encapsulation membrane after its implantation in mini-pigs.

The biocompatibility of membranes aiming at being a part of a bioartificial pancreas has been tested. For that purpose, we have studied a polycarbonate membrane surface after its implantation in mini-pigs. The membranes were made hydrophilic by an argon plasma surface treatment followed by a dipping in a hydrophilic polymer solution.

Social and health determinants of the efficiency of cotton farmers in Northern Côte d'Ivoire.

This article assesses the role of malaria and some social determinants on the agricultural development and more precisely on efficiency in the context of cotton crop in the Korhogo region in the North of Côte d'Ivoire. Data envelopment analyses (DEA) was first applied for the purpose of calculating relative efficiencies in production. A Tobit regression model was then used to explain the variation in the DEA scores and check the hypotheses that the efficiency deviations between farmers can be explained by the disparity of malaria morbidity rate among the farmers and their family, by social cohesiveness and cultural behaviour.
