The catastrophic flash-flood event of 8–9 September 2002 in the Gard region, France: a first case study for the Cévennes–Vivarais Mediterranean Hydrometeorological Observatory

The Cévennes–Vivarais Mediterranean Hydrometeorological Observatory (OHM-CV) is a research initiative aimed at improving the understanding and modeling of the Mediterranean intense rain events that frequently result in devastating flash floods in southern France. A primary objective is to bring together the skills of meteorologists and hydrologists, modelers and instrumentalists, researchers and practitioners, to cope with these rather unpredictable events. In line with previously published flash-flood monographs, the present paper aims at documenting the 8–9 September 2002 catastrophic event, which resulted in 24 casualties and an economic damage evaluated at 1.2 billion euros (i.e., about 1 billion U.S. dollars) in the Gard region, France. A description of the synoptic meteorological situation is first given and shows that no particular precursor indicated the imminence of such an extreme event. Then, radar and rain gauge analyses are used to assess the magnitude of the rain event, which was particularly remarkable for its spatial extent with rain amounts greater than 200 mm in 24 h over 5500 km2. The maximum values of 600–700 mm observed locally are among the highest daily records in the region. The preliminary results of the postevent hydrological investigation show that the hydrologic response of the upstream watersheds of the Gard and Vidourle Rivers is consistent with the marked space–time structure of the rain event. It is noteworthy that peak specific discharges were very high over most of the affected areas (5–10 m3 s−1 km−2) and reached locally extraordinary values of more than 20 m3 s−1 km−2. A preliminary analysis indicates contrasting hydrological behaviors that seem to be related to geomorphological factors, notably the influence of karst in part of the region. An overview of the ongoing meteorological and hydrological research projects devoted to this case study within the OHM-CV is finally presented.

Limiar anaeróbio e velocidade crítica determinada com diferentes distâncias em nadadores de 10 a 15 anos: relações com a performance e a resposta do lactato sanguíneo em testes de endurance

O objetivo deste estudo foi comparar a velocidade crítica (VC) determinada através de diferentes distâncias com o limiar anaeróbio (LAn) e as velocidades máximas mantidas em testes de 20 (V20) e 30 (V30) minutos na natação, verificando se a idade cronológica em jovens nadadores interfere nessas relações. Participaram do estudo 31 nadadores (17 meninas e 14 meninos) divididos segundo a idade cronológica em dois grupos: 10 a 12 anos e 13 a 15 anos. O LAn foi determinado como sendo a velocidade correspondente a 4mM de lactato sanguíneo. A VC1 (25/50/100m), VC2 (100/200/400m) e a VC3 (50/100/200m) foram calculadas através do coeficiente angular da reta de regressão linear entre as distâncias e seus respectivos tempos. As V20 e V30 foram determinadas através de três a seis repetições, com coletas de sangue no 10º minuto e ao final do tiro. Para o grupo de 10 a 12 anos, a VC1 (m/s) (0,98 ± 0,17) e o LAn (0,97 ± 0,12) não foram diferentes entre si, sendo maiores do que a VC2 (0,92 ± 0,16), VC3 (0,89 ± 0,18), V20 (0,92 ± 0,11) e V30 (0,90 ± 0,11). Para o grupo de 13 a 15 anos, a VC1 (m/s)(1,11 ± 0,11) foi maior do que o LAn (1,02 ± 0,07), V20 (0,99 ± 0,09), V30 (0,97 ± 0,09), VC2 (0,98 ± 0,11) e VC3 (1,00 ± 0,11). Pode-se concluir que a distância utilizada na determinação da VC interfere no valor obtido, independente da idade cronológica. A VC determinada com distâncias entre 50 e 400m pode ser utilizada na avaliação da capacidade aeróbia de crianças e adolescentes, substituindo os testes contínuos máximos com durações próximas a 20 ou 30 minutos.

Compostos fenólicos de 10 variedades de uva

Phenolic compounds represent one of the main groups of secondary metabolites. Due to their chemical diversity, they have a variety of functions in plants, such as protection against ultraviolet radiation, herbivores and pathogens, and attraction of pollinators or dispersers of fruits and seeds. For human, the phenolic compounds are used like food colorings and flavors and, due to their pharmacological properties, mainly to antioxidant activity, they are associated with several health benefits, such as delay senility, prevention and therapy of cardiovascular diseases and of some cancers. The grapes are considered one of the main source of phenolic compounds and the fruit and its products are consumed in Brazil and worldwide. Considering the phenolic compounds diversity and their different distribution in the grape parts, this work had like aims the extraction, identification and quantification of the main classes of phenolic compounds of 10 grape varieties. The content of total phenols, flavanols and anthocyanins were determined, respectively, according to the Folin-Ciocalteu, DMACA and comparison of pH spectrophotometric methods. The content of total phenols varied from 142.75 + 1.86 to 483.39 + 5.90 mg.L-1 in the peel and from 86.50 + 0.54 to 146.32 + 9.97 mg.L-1 in the pulp. The amount of total flavanols varied from 3.68 + 0.03 to 6.92 + 0.26 mg.L-1 in the peel and from 0.90 + 0.00 to 1.36 + 0.00 mg.L-1 in the pulp. The content of total anthocyanins varied from 7.00 + 0.99 to 406.56 + 39.50 mg.L-1 in the peel and from 2.88 + 0.28 to 46.36 + 1.89 mg.L-1 in the pulp. The phenolic compounds concentration was higher in the peel than in the pulp. The total phenols and anthocyanins varied a lot while the total flavanols were more constant. The flavanols represent the smaller portion of phenolic compounds

Molecular epidemiology of extended-spectrum-beta-lactamase-producing Klebsiella pneumoniae over a 10 year period in Calgary, Canada

A study was designed to investigate the molecular epidemiology of extended-spectrum -lactamase (ESBL)-producing Klebsiella pneumoniae isolated in a centralized region over a 10 year period (200009). Molecular characterization was done using isoelectric focusing, PCR and sequencing for bla(CTX-M), bla(TEM) and bla(SHV) genes and plasmid-mediated quinolone resistance determinants. Genetic relatedness was determined with PFGE using XbaI and multilocus sequencing typing. A total of 89 patients with incident infections were identified; the majority presented with hospital-onset urinary tract infections. The absolute number of ESBL-producing isolates remained very low until 2003, increased slightly in 2004, remained stable until 2008 and then in 2009 there was an abrupt increase in the numbers of ESBL producers identified. The majority of K. pneumoniae produced CTX-M-14 and -15, and have replaced SHV-12-producing isolates since 2005. We identified four different major sequence types (STs) among 32 of isolates (i.e. ST17, ST20, and the new ST573 and ST575) and provided insight into their clinical and molecular characteristics. The ST isolates were more likely to produce community-onset infections, were associated with bla(CTX-M) and emerged during the latter part of the study period. ST17 produced CTX-M-15 and SHV-12, and was more likely to be positive for qnrB; ST20 produced CTX-M-14 and was positive for qnrS. The multiresistant ST575 that produced CTX-M-15 appeared in 2009. Our study highlights the importance of molecular epidemiology in providing insight into the emergence, characteristics and distribution of STs among ESBL-producing K. pneumoniae.

Activation of PAF-receptor induces regulatory dendritic cells through PGE2 and IL-10

Activation of the platelet-activating factor receptor (PAFR) in macrophages is associated with suppressor phenotype. Here, we investigated the PAFR in murine dendritic cells (DC). Bone marrow-derived dendritic cells (BALB/c) were cultured with GM-CSF and maturation was induced by LPS. The PAFR antagonists (WEB2086, WEB2170, PCA4248) and the prostaglandin (PG) synthesis inhibitors (indomethacin, nimesulide and NS-398) were added before LPS. Mature and immature DCs expressed PAFR. LPS increased MHCII, CD40, CD80, CD86, CCR7 and induced IL-10, IL-12, COX-2 and PGE2 expression. IL-10, COX-2 and PGE2 levels were reduced by PAFR antagonists and increased by cPAF. The IL-10 production was independent of PGs. Mature DCs induced antigen-specific lymphocyte proliferation. PAFR antagonists or PG-synthesis inhibitors significantly increased lymphocyte proliferation. It is proposed that PAF has a central role in regulatory DC differentiation through potentiation of IL-10 and PGE2 production.
