Background: Gold-standard method for malaria diagnosis is microscopic examination of Giemsa stained thick and thin blood smears. This method is cheap and simple but fastidious and requires experienced microscopists. In recent years, molecular biology techniques have been applied with success in the microbiology field because of their great sensitivity and specificity. The aim of this study is the evaluation of Polymerase Chain Reaction (PCR) in the detection of low parasitaemia and mixed infections. Methods: A total of 191 blood samples were included in the study. They were collected from patients admitted to hospital because of suspicion of malaria infection, and distributed as follows: 105 from Liege (Belgium), 42 from Lubumbashi (Democratic Republic of Congo), and 44 from Cayenne (French Guiana). Two PCR techniques targeting the small sub-unit rRNA gene of Plasmodium were tested in comparison with microscopy. The real-time PCR was specific of Plasmodium sp. and the semi-nested multiplex PCR was able to detect each of the four species. Results: The real-time PCR sensitivity was 97% and 100% for multiplex PCR. The specificity of both techniques was 96%. Multiplex PCR detected 2 mixed infections that were missed by microscopy. In 4 cases, both PCR techniques permit to detect parasitaemia after treatment while microscopy was already negative. In one case, parasite DNA was detected by PCR one day before the microscopy became positive. Conclusions: Both PCR techniques presented the same detection limit. The PCR methods had a better sensitivity than microscopy. They detected P. falciparum and P. vivax respectively 7 and 6 days after beginning of treatment. Multiplex PCR allowed species identification and mixed infection determination that could confirm and complete the microscopic examination. Real-time PCR was quicker than nested PCR and could be used for screening in addition to the gold-standard method [less ▲]

Si, au fil du 20ème siècle, le sport est devenu un véritable phénomène social et économique, l’activité physique semble prendre une place croissante dans les préoccupations actuelles. Les deux concepts sont parfois utilisés sans discernement. Nous considérons toutefois qu’ils se réfèrent à des significations différentes. Dès lors, il s’avère important de les distinguer afin de mieux percevoir les modalités de pratique auxquels ils sont associés et de comprendre les nuances pouvant exister au niveau des acteurs chargés de leur organisation. Le sport est défini comme étant «toutes formes d’activités physiques qui, à travers une participation organisée ou non, ont pour objectif l’expression ou l’amélioration de la condition physique et psychique, le développement des relations sociales ou l’obtention de résultats en compétition de tous niveaux » (Conseil de l’Europe, 1992). De son côté, l’activité physique « comprend tout mouvement du corps produit par les muscles squelettiques et qui résulte en une augmentation substantielle par rapport à la dépense d’énergie de repos » (Bouchard & Shephard, 1993). Elle peut être sportive, associée au travail, aux tâches domestiques, aux déplacements ou encore aux loisirs (Sallis, Cervero, Ascher, Henderson, Kraft & Kerr, 2006). Il apparaît clairement que le concept d’activité physique englobe le sport, ce dernier n’étant qu’une forme d’activité physique. Ceci présente des implications particulièrement importantes lorsqu’il s’agit d’étudier la place et le rôle des personnes qui agissent sur le terrain et que l’on associe de plus en plus à l’effort réalisé actuellement pour lutter contre la sédentarité croissante de la population mondiale, dans la perspective de maintenir un état de santé socialement acceptable. Le terme « éducateur physique » est une expression tirée du vocabulaire québécois. [less ▲]

Aphidius ervi (Hymenoptera: Braconidae) is an entomophagous parasitoid known to be an effective parasitoid of several aphid species of economic importance. A reduction of its production cost during mass rearing for inundative release is needed to improve its use in biological control of pests. In these contexts, a careful analysis of its entire development phases within its host is needed. This paper shows that this parasitoid has some characteristics in its embryological development rather complex and different from most other reported insects, which can be phylogenetically very close. First, its yolkless egg allows a high fecundity of the female but force them to hatch from the egg shell rapidly to the host hemocoel. An early cellularisation allowing a rapid differentiation of a serosa membrane seems to confirm this hypothesis. The serosa wraps the developing embryo until the first instar larva stage and invades the host tissues by microvilli projections and form a placenta like structure able to divert host resources and allowing nutrition and respiration of embryo. Such interspecific invasion, at the cellular level, recalls mammal's trophoblasts that anchors maternal uterine wall and underlines the high adaptation of A. ervi to develop in the host body.

It is now well established that during the second half of normal pregnancy, the human placenta secretes its specific GH variant (placental GH) in increasing amounts up to delivery. During the same period, pituitary GH secretion is progressively suppressed. The present study was aimed at clarifying the physiology of GH secretion in pregnant acromegalic women. Two young women remained acromegalic despite transphenoidal removal of their pituitary adenoma. Increased basal levels of GH and insulin-like growth factor-I (IGF-I) as well as paradoxical GH release after TRH injection were noted. Both women became pregnant and delivered term babies without any complication. In both patients, pituitary GH remained elevated during the entire pregnancy, contrary to the situation in normal women. Paradoxical GH release after TRH treatment was also present, whereas no response was observed in five normal control subjects. GH pulsatility studies revealed a highly pulsatile secretory pattern of pituitary GH, in contrast to that in normal woman, whose placental GH is secreted tonically. Tissue placental GH concentrations were within the range of levels in normal placentas. An increase in serum IGF-I in late pregnancy was also similar to that observed in normal pregnancy. These findings confirm that increased IGF-I levels are not pituitary GH dependent in late pregnancy. They add new evidence that adenomatous somatotrophs lack an IGF-I-dependent feedback regulation present in normal somatotrophs. [less ▲]

The prediction of birth weight may be improved by the measurement of hormones or growth factors in the mother. We measured body weight (BW) and plasma levels of placental GH (PGH), IGF-I, IGF-binding protein-1 (IGFBP-1), and leptin at the time of the glucose challenge test (GCT) in 289 women, who were pregnant with a single fetus, between 24 and 29 wk gestational age (GA). Delivery occurred 12 +/- 2 (mean +/- SD) wk later. First, we examined which variables regulate these hormonal factors. Multiple regression showed that PGH concentrations were determined by GA at sampling and were negatively related to BW. IGF-I levels were mainly determined by PGH, and also by insulin, BW, and (negatively) age. IGFBP-1 concentrations were negatively determined by BW, insulin, and IGF-I. BW was also a powerful determinant of leptin levels, with insulin as a less robust determinant. Second, we examined the relation to glucose levels. PGH, IGF-I, and IGFBP-1 concentrations were not correlated with post-GCT glucose levels and were comparable in women with a normal or disturbed GCT (glucose >/=7.8 mmol/liter; n = 72). Finally, we examined the relation with birth weight and placental weight. Birth weight, corrected for GA and stratified into percentile groups, and the ponderal index at birth were strongly related to maternal BW, but not to maternal PGH, IGF-I, or IGFBP-1 levels. Neither was maternal leptin related to birth weight, but leptin concentrations were slightly higher in women who delivered obese babies. Placental weight was not related to any of the hormonal factors. This prospective study indicates that the variation in circulating PGH, IGF-I, IGFBP-1, and leptin between 24 and 29 wk of pregnancy is strongly dependent on maternal BW, but is unrelated to glucose tolerance. In addition, the measurement of PGH, IGF-I, IGFBP-1, or leptin at the time of the GCT is not useful clinically to predict birth weight. [less ▲]
