TL;DR: A full and possibly irreversible widespread of Z. tritci QoI resistance in Northern France is highlighted and a lack of recent introduction of sensitive genotypes to this region from other areas is indicated, indicating that maintaining the use in the field, but in a reasoned manner, of other fungicide classes such as DMIs and SDHIs to manage Z.tritici is therefore still strongly justified.

TL;DR: The use of the new fingerprint recorded for P. globosa improved the detection of Isochrysis sp .T his suggests the possibility of using the FluoroProbe to monitor Haptophytes other than P. Globosa by calibrating the device with species representative of the region of interest.
Abstract: In this study, we examined the possibility of using the FluoroProbe for monitoring the dynamics of the Haptophyte Phaeocystis globosa in the coastal waters of the eastern English Channel. The FluoroProbe was recalibrated by recording a new fingerprint for P. globosa and the use of this new fingerprint was tested through a series of laboratory and in situ experiments. The annual dynamics of P. globosa estimated using the FluoroProbe and by flow cytometry were similar. A strong relationship was found between the FluoroProbe estimates of P. globosa biomass expressed in terms of chlorophyll a equivalent per litre (eq. m gL 21 ) and flow cytometric cell counts (r ¼ 0.889, P , 0.001, n ¼ 121). The FluoroProbe can be used to detect the flagellated cells as well as the colonial cells of P. globosa but not to distinguish these two cell types in mixed assemblages. The use of the new fingerprint recorded for P. globosa improved the detection of Isochrysis sp .T his suggests the possibility of using the FluoroProbe to monitor Haptophytes other than P. globosa by calibrating the device with species representative of the region of interest. However, it is important to note that the detection of P. globosa at the species level was possible in the eastern English Channel because it was the only Haptophyte species present with a biomass sufficient to be detected by the FluoroProbe. In areas where several Haptophyte species are simultaneously present, their discrimination will be impossible and in such situations the FluoroProbe can be used to monitor the dynamics of the combined Haptophyte group.

TL;DR: It is concluded that the occurrence of dramatic MS alterations in 3p chromosome multiple critical regions could be a crucial underlying mechanism, which proceeded the lung toxicity in air pollution PM-exposed target L132 cells.

TL;DR: It is concluded that urban children have higher lead (Pb) levels than rural children, and that of these children, boys have higher B-Pb levels than girls, leading thereby to alterations of heme biosynthesis and pro-oxidant/antioxidant balance.
Abstract: Leaded-gasoline is probably the primary source of lead (Pb) exposure in Dakar (Senegal). The present crosssectional study was undertaken to investigate the levels of Pb in Senegalese children and to present helpful data on the relationship between Pb levels and changes in biological markers of heme biosynthesis and oxidative stress. A total of 330 children, living since birth either in rural or urban areas (ie, Khombole (n /162) and Dakar (n /168), respectively) were included. During this crosssectional study, the mean blood (B)-Pb level in all children was 7.329 /5.33 mg/dL, and was influenced by the area of residence and gender. In rural children, 27 subjects (16.7%), 18 boys (19.6%) and nine girls (12.9%), had a B-Pb level � /10 mg Pb/dL, whereas 99 urban children (58.9%), respectively, 66 boys (71.8%) and 33 girls (43.4%), had alarmingly high B-Pb levels. Accordingly, urine delta-aminolevulinic acid levels were higher in children living in the urban area than in the rural areas (P B /0.001), and closely correlated with the B-Pb levels (P B /0.01). Moreover, glutathione peroxidase (GPx) activity, selenium (Se) level, glutathione reductase (GR) activity, and glutathione status were significantly influenced by area of residence and/or by gender. GPx activity and Se level were not only negatively correlated with B-Pb levels, but also positively correlated together (P B /0.01). Taken together, the present results allow us to conclude that urban children have higher B-Pb levels than rural children, and that of these children, boys have higher B-Pb levels than girls, leading thereby to alterations of heme biosynthesis and pro-oxidant/antioxidant balance. We also suggest that exposure to Pb and the Pb-induced adverse effects merits attention and that the development of preventive actions are of increasing importance in Senegal.
