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.

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 ▲]

We study the lexical learning by children who have a genetic syndrome leading to mental retardation, the Down syndrome. Children with Down syndrome learn the names of new objects displayed in a scene. Our contribution explore to what extent the context associated with the object is beneficial or detrimental to the association between an object and its name in recall, production and a comprehension tasks. We assessed whether children with Down syndrome could learn four non-words associated with unfamiliar animals or musical instruments displayed in a scene (the context of presentation) and whether their performance would be influenced by the congruence of the context of presentation between the learning and the test phases. We hypothesized that the contextual congruence between the learning and the test will enhance children’s performance. In contrast, the association between an object and a new context in the test phase (compared to the association in the learning phase) would decrease performance. The results don’t confirm completely our hypothesis. There is no effect of context of presentation in recall and comprehension tasks. The effect of context of presentation is present only in denomination task. We compare this results with those of “normal” children. Consequences on lexical learning are discussed. [less ▲]

Studies of monolingual speakers have shown a strong association between lexical learning and short-term memory (STM) capacity, especially STM for serial order information. At the same time, studies of bilingual speakers suggest that phonological knowledge is the main factor that drives lexical learning. This study tested these two hypotheses simultaneously in participants with variable levels of English-French bilingual proficiency. A word-nonword paired-associate learning task was administered, with nonwords obeying French phonotactic patterns. French phonological knowledge was estimated by a composite French proficiency score summarizing productive and receptive French vocabulary knowledge as well as quantitative and qualitative measures of French exposure. STM measures maximized retention of order information (serial order reconstruction) or retention of phonological item information (single nonword delayed repetition). The French proficiency score and the serial order STM measure independently predicted performance on the paired-associate learning task. These results highlight the conjoined role of phonological knowledge and serial order STM in lexical learning. Importantly, serial order STM remains a strong predictor of lexical learning, even for bilingual individuals who have broad phonological knowledge. [less ▲]

This volume is the first to be devoted specifically to the study of lexical semantics in Ancient Egyptian. While much research has been dedicated to a wide range of grammatical issues in past decades, lexical semantics has rarely been treated in a systematic fashion. The papers collected here treat a range of semantic phenomena, from the lexical semantics of spatial expressions, to the problems of analyzing polyfunctionality and even to the semantics of the Egyptian writing system. The scope of these issues goes well beyond the individual 'word' or lexical item, as a number of papers address the semantics of syntactic constructions. Some authors call into question the distinction between lexicon and grammar, or analyze the lexical semantics of items usually considered 'grammatical' or 'function' words, such as discourse particles. This volume also spans a number of theoretical frameworks and methodologies that have not been prominent in Egyptian linguistics and philology, such as typologically-oriented semantic maps and other visual tools. The papers in this volume do not aim to define the 'state of the art,' but rather seek to stimulate the study of meaning in Ancient Egyptian, to point to innovative avenues for future research, and to engage in a broader dialogue between Egyptian linguistics and philology, on the one hand, and the research frameworks and agendas of general linguistics, on the other.

Using text statistics for qualitative analysis is surely a paradox - counting words in an approach where "numbers doesn't count". Hence, we were stunned by the repeated expectation of text mining features from the users of our qualitative analysis platform. Reluctant at first to methodological hybridizations that could be seen as flawed, we then had to admit that even the founders of qualitative analysis envisioned qualitative ways to use statistics. Counts cannot be regarded as proofs by qualitative analyzers, but as clues for an interpretation, as incentives to look closer at the materials. To achieve this goal, we designed a new visualization of text statistics,displayed in the text without any numbers nor tables. [less ▲]
