Detection of a new 3-base pair insertion mutation in the protease gene of human immunodeficiency virus type 1 during highly active antiretroviral the…
2005
To investigate a new insertion mutation in the protease (PR) gene of human immunodeficiency virus type 1 (HIV-1) in a patient extensively pretreated with antiretroviral drugs, genotypic analyses of plasma-derived viruses were performed by sequencing segments of 1302 nucleotides in the pol gene of HIV-1. Despite optimal compliance to highly active antiretroviral therapy (HAART) the patient showed poor virological success. Nucleotide sequences of retrospective available plasma samples exhibited a previously unknown 3-bp insertion mutation, corresponding to a leucine, between codons 31 and 32 of the PR gene. This kind of mutation appears to be very rare and it does not seem to be associated wi…
Oocyte insemination techniques are related to alterations of embryo developmental timing in an oocyte donation model
2013
Because of the different intrinsic characteristics of the classic IVF and intracytoplasmic sperm injection (ICSI) techniques, the timing of zygote development can be influenced by the method of fertilization. However, there is no information about the relevance of the insemination procedure on embryo-quality parameters as measured through their developmental dynamics. The aim of this work was to determine if the insemination technique, IVF or ICSI, influences embryo developmental kinetics by examining 1203 embryos from 178 couples undergoing oocyte donation with IVF or ICSI. Using time-lapse information, this work calculated several developmental kinetic variables, from pronuclear fading (P…
Inter-cycle and inter-observer variability of the antral follicle count in routine clinical practice
2017
Antral follicle count (AFC) is a reliable predictor of ovarian response to stimulation and its inter-cycle and inter-observer variability has been extensively studied on in vitro fertilization (IVF), mostly in highly selected populations within studies not originally designed for this purpose. In this retrospective cohort study, we assess the inter-cycle variation of AFC in a setting similar to that of the daily practice. We included only patients undergoing mild stimulation for intrauterine insemination (IUI). One hundred and forty-eight patients had two (62 patients, group A), three (49 patients, group B) or four (37 patients, group C) IUI cycles and AFC was measured on early follicular p…
The requirement for the inclusion of formulation efficacy trials in pesticide preregistration evaluations
2008
BACKGROUND: Optimization of biocide use could serve to reduce the risks of biocides on human health. To optimize the risk/benefit ratio, it is important to develop procedures for evaluating the efficacy of biocide formulations. The authors examined the effectiveness of ten pyrethroid insecticide aerosol formulations registered for the household control of flies. Tests were performed using adult Musca domestica L. Knockdown effects and mortality were measured in a test chamber using the manufacturer's recommended discharge time. RESULTS: The knockdown effect varied greatly between aerosols of similar composition. The knockdown 15 min post-treatment was 66–98% for flies placed 120 cm above fl…
Mitogenomics of the Olive Seed Weevil, Anchonocranus oleae Marshall and Implications for Its Phylogenetic Position in Curculionidae
2022
Anchonocranus oleae Marshall (Coleoptera: Curculionidae) is a seed-feeding weevil native to southern Africa; its larvae are known to develop in the fruits of the African Wild Olive and, more rarely, cultivated olives. The species has been mainly found in the Western Cape province of South Africa, but it has remained in relative obscurity because it does not seem to represent a current threat to commercial olive production. As part of an ongoing effort to produce baseline genetic data for olive-associated entomofauna in South Africa, we generated reference DNA barcodes for A. oleae collected from wild and cultivated olives and sequenced its mitogenome for assessment of the phylogenetic posit…

L'insertion professionnelle et la formation en cours d'emploi
1994
International audience; Que l'éducation joue un rôle essentiel dans tout processus de développement, tous les travaux convergent pour l'affirmer. Il en est ainsi de ceux des macroéconomistes qui lui attribuent une part importante des taux de croissance, et des analystes du rendement de l'éducation qui calculent des taux de rendement, surtout dans le primaire, plus élevés que ceux de la majorité des investissements industriels. Quant aux enquêtes de terrain, elles montrent que les agriculteurs et petits entrepreneurs éduqués ont des productivités plus élevées que celles de leurs homologues qui ne le sont pas. En Afrique, malgré des dépenses relativement élevées consacrées à l'éducation, les …
