Intraoperative blood salvage devices allowing a reinfusion of red blood cells (RBCs) after processing of shed blood and stagnant blood in the mediastinal cavity are more and more used to reduce homologous blood requirements in cardiac surgery with cardiopulmonary bypass (CPB). As the proinflammatory activity of the shed blood also contributes to morbidity during CPB, we conducted a prospective study in order to examine the quality of autologous blood before and after processing with five different devices [BRAT2, Sequestra, Compact Advanced, Cell Saver 5 (CS5), Continuous Autologous Transfusion System (CATS)]. All systems resulted in an excellent haemoconcentration, ranging from 53.7% (Compact) to 68.9% (CATS). The concentrations and elimination rates of several inflammatory markers [IL-1beta, IL-2, IL-8, TNFalpha, myeloperoxidase (MPO), elastase] were examined. Except for the Sequestra, an important increase in concentration of IL-1beta (between 30% and 220%) has been observed after processing with each device. In contrast, the attenuation rate of IL-6 and TNFalpha (95%) was optimal for all investigated blood salvages systems. Regarding IL-8, only the CATS and CS5 systems were able to attenuate this biological parameter with an excellent efficacy. The rate of attenuation in MPO and elastase, as markers of leukocyte activation, was higher than 80% for all devices. In conclusion, the different RBC washing systems tested in this study resulted in a significant attenuation of the inflammatory response. Increased levels of IL-1beta after processing remained, however, unclear. According to the type of protocol, based on inlet haematocrit, fill and wash speeds, and wash volumes, small variations in reducing the inflammatory response have been observed from one device to another.

Congener-specific analyses of polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) and polychlorinated biphenyls (PCBs) were performed on twenty-eight non-pooled fast food samples collected in Belgium, Switzerland, Czech Republic, United States of America and Australia. PCDD/F and PCB concentrations for the four investigated types of meals were very low. PCDD/F values ranged from non-detected to 1.40 pg WHO-TEQ/g fat and from 0.79 to 2.08 pg WHO-TEQ/g fat for lower and upper bound, respectively. Major contributors to the PCDD/F TEQ were 1,2,3,4,7,8-HxCDD, 1,2,3,6,7,8-HxCDD, 2,3,7,8-TCDF and 2,3,4,7,8-PeCDF. The relative contribution of PCBs to the total TEQ was 68%. For adults, an average estimated intake was 6.7 pg WHO-TEQ/kg bw/month, including consumption of all types of analyzed meals, representing 9.5% of the PTMI. For child, a value of 14.5 pg WHO-TEQ/kg bw/month was obtained, representing 20.6% of the PTMI. (C) 2003 Elsevier Ltd. All rights reserved. [less ▲]

Wereport on the pilot study carried out before the start of the Elfe project (French longitudinal study from childhood). A total of 44 samples of mature human milk were collected at home 8 weeks after delivery. A total of 7 polychlorinated dibenzo-p-dioxins (PCDDs), 10 polychlorinated dibenzofurans (PCDFs), 12 dioxin-like (DL) polychlorinated biphenyls (PCBs), and 6 non dioxin-like (NDL)-PCBs were measured. For total TEQ (PCDD/Fs and DL-PCBs), the geometric mean concentration was 17.81 pg TEQWHO05/g lipids. Relative PCDD, PCDF, and DL-PCB contributions to the arithmetic mean TEQWHO05 were 38%, 18%, and 44%, respectively. The use of TEFWHO05 instead of TEFWHO98 resulted in a 27% reduction of the total TEQ value. Although PCDD levels did not significantly change (less than 0.5% increase), PCDF and DL-PCB levels both decreased by 35% and 38%, respectively. Levels have been compared to data obtained during a previous non-reported national study conducted in 1998 (TEFWHO98) in French lactaria (n = 244). The mean of PCDD/Fs has decreased about 39.4% (18.8 pg TEQWHO98/g lipids in 1998 vs 11.4 pg TEQWHO98/g lipids in pilot study), respectively 41.5% for PCDDs (10.6 pg TEQWHO98/g lipids in 1998 vs 6.2 pg TEQWHO98/g lipids in pilot study) and 36.7% for PCDFs (7.9 pg TEQWHO98/g lipids in 1998 vs 5.0 pg TEQWHO98/g lipids in pilot study). For the sum of the 6 NDL-PCBs, the 2007 geometric mean concentration in milk was 176.3 ng/g lipids. The arithmetic mean lipid concentration in 2007 breast milk was 26.4 g/l (range from 6.0 to 46.7 g/l). A PCDD/F and DL-PCB daily intake was estimated to be 62.3 pg TEQWHO05/kg body weight per day (85.0 pg TEQWHO98/kg bodyweight per day) for a baby of 5 kg of bodyweight fed daily with 700 ml of maternal milk containing 25 g/l of lipids.

Depuis les années 60, la fréquence de mutations organisationnelles de l'enseignement supérieur et universitaire en Belgique s'amplifie et adopte même un rythme frénétique ces dix dernières années. Les causes sont tour à tour l'évolution des professions et la volonté politique et/ou économique de restructuration. Deux niveaux de régulations pédagogiques sont amenés à s'articuler. D'une part, celui de l'enseignant acteur-réflexif de son enseignement et d'autre part, des injonctions externes qui réorganise le cadre général.

Normal aging is associated with a decrease in dopaminergic function and a reduced ability to form new motor memories with training. This study examined the link between both phenomena. We hypothesized that levodopa would (a) ameliorate aging-dependent deficits in motor memory formation, and (b) increase dopamine availability at the dopamine type 2-like (D2) receptor during training in task-relevant brain structures. The effects of training plus levodopa (100mg, plus 25mg carbidopa) on motor memory formation and striatal dopamine availability were measured with [(11)C]raclopride (RAC) positron emission tomography (PET). We found that levodopa did not alter RAC-binding potential at rest but it enhanced training effects on motor memory formation as well as dopamine release in the dorsal caudate nucleus. Motor memory formation during training correlated with the increase of dopamine release in the caudate nucleus. These results demonstrate that levodopa may ameliorate dopamine deficiencies in the elderly by replenishing dopaminergic presynaptic stores, actively engaged in phasic dopamine release during motor training.

Inflectional spelling abilities have been less extensively studied than lexical spelling abilities and the relationship between these two types of spelling abilities is poorly understood. In this study, we compared lexical and inflectional spelling abilities in 12-year-old children, by hypothesizing that attentional load may be particularly detrimental for sentence context-dependent inflectional spelling abilities, in contrast to sentence context-independent lexical spelling abilities. Ninety-five sixth graders had to write to dictation sentences containing orthographically inconsistent words as well as inflected words (plural nouns and verbs at the 3th person) in three different cognitive load conditions. In a medium load condition, a time constraint obliged the subjects to write the sentences as quickly as possible. In a high load condition, the participants had to write the sentences as quickly as possible while further carrying out calculation problems (additions). The minimal load condition corresponded to standard writing to dictation, with no time constraint or any secondary task. The number of spelling errors for orthographically inconsistent words (lexical spelling abilities) and inflected words (inflectional spelling abilities) was calculated for each condition. We observed that spelling performance for inconsistent words was not impacted by cognitive load. On the other hand, spelling performance for inflected words decreased significantly in the medium and high load conditions. These results suggest that inflectional spelling abilities are less proceduralized than lexical spelling abilities, and rely to a greater extent on cognitive control processes. [less ▲]
