Analysis of the distribution of HII regions in external galaxies. IV The new galaxy sample. Position and Inclination angles
We have compiled a new sample of galaxies with published catalogs of HII
region coordinates. This sample, together with the former catalog of
Garcia-Gomez and Athanassoula (1991) will form the basis for subsequent studies
of the spiral structure in disc galaxies. In this paper we address the problem
of the deprojection of the galaxy images. For this purpose we use two
deprojection methods based on the HII region distribution and compare the
results with the values found in the literature using other deprojection
methods. Taking into account the results of all the methods, we propose optimum
values for the position and inclination angles of all the galaxies in our
sample.Comment: TeX file with 16 postscript figure

Approche anthropologique de la pandémie de covid-19 : pratiques thérapeutiques néo-traditionnelles d’un fundi à l’île de La Réunion
International audienceThis article presents an ethnographic field survey carried out on Reunion Island during the first year of the covid-19 pandemic. This study concerns the neo-traditional therapeutic practices of a fundi originating from the Comoros archipelago. Our objective is to identify and analyze the mechanisms at work in the processes of reinterpreting biomedicine during this pandemic context. Our analysis shows how this collective ordeal is transformed into a professional resource by a fundi. Health recommendations such as containment measures and barrier gestures push the fundi to adapt its practice through the establishment of « ritual teleconsultations ». Our field also shows a fundi that gives meaning to this pandemic through plural explanatory models (biomedical and sacred) and the manufacture of talismanic objects called hirizi integrated into protective masks. The findings show the use of traditional syncretic therapy practices that are not new. In all cases, recourse to religion is omnipresent through magico-Islamic ritual practices, the fundi of which builds symbolic effectiveness by transposing them to the biomedical model.Cet article présente une enquête ethnographique de terrain réalisée à l'île de La Réunion durant la première année de pandémie de la covid-19. Cette étude concerne les pratiques thérapeutiques néo-traditionnelles d'un fundi originaire de l'archipel des Comores. Notre objectif est d'identifier et d'analyser les mécanismes à l'oeuvre dans les processus de réinterprétation de la biomédecine durant ce contexte pandémique. Notre analyse montre comment cette épreuve collective est transformée en ressource professionnelle par un fundi. Les recommandations sanitaires telles que les mesures de confinement et les gestes barrières poussent le fundi à adapter sa pratique à travers la mise en place de « téléconsultations rituelles ». Notre terrain décrit également un fundi qui donne sens à cette pandémie à travers des modèles explicatifs pluriels (biomédicaux et sacrés) et la fabrication d'objets talismaniques nommés hirizi intégrés à des masques de protection. Les conclusions montrent l'utilisation de pratiques thérapeutiques traditionnelles syncrétiques qui ne sont pas nouvelles. Dans tous les cas, le recours au religieux est omniprésent à travers des pratiques rituelles magico-islamiques dont le fundi construit l'efficacité symbolique en les transposant au modèle biomédical
Etude de la composition chimique et du potentiel pharmacologique associé de Phyllanthus amarus Schum et Thonn. (1827) « Grenn anba fèy »
International audienceAbstract:In August 2013, the French pharmacopoeia was enriched with 43 plants used in French overseas territories, including 15 proposed by APLAMEDAROM association of Guadeloupe. However, for most of them, no data on the chemical composition, qualitatively and quantitatively is available in the literature for these specimens; this is an issue to their commercialization in dispensary, pharmacists wishing to know their composition in order to avoid the problems of dosage and drug interactions. Among these plants, Phyllanthus amarus Schum. & Thonn. (1827), commonly called "Grenn anba fèy" [1], is well known for its potent medicinal properties especially hepatoprotective, antidiabetic, antiviral (flu), anti-inflammatory, anti-cholesterol [2]. In Guadeloupe, this plant is generally used freshly harvested in infusion but also in aqueous decoction [3]. Besides, these studies are conducted in association with APLAMEDAROM association in order to identify the polar constituents and then to understand better the origin of the observed properties. Therefore, using UHPLC-MS, we were able to identify the presence of bioactive polyphenolic compounds, including phyllanthin, rutin and gallic acid. Phyllanthin, characteristic of the specie, is a very active lignan with high antioxidant, hepatoprotective and anticancer properties [2]. Rutin is known for its antioxidant and anti-hypertensive properties [2]. Gallic acid is distinguished by antioxidant, anti-inflammatory, antidiabetic, antiviral and anticancer properties and has the advantage of being a bioavailable compound. Similarly, many compounds never listed to date in this specie were also highlighted and are currently purified.Résumé :En août 2013, la pharmacopée française s'est enrichie de 43 plantes utilisées dans les outremers dont 15 ont été proposées par l'association APLAMEDAROM de Guadeloupe. Cependant, pour la majorité d'entre elles, aucune donnée sur la composition chimique, au niveau qualitatif et quantitatif, n'est disponible dans la littérature ; ce qui représente un véritable obstacle à leur commercialisation, les pharmaciens souhaitant mieux connaître leurs constituants afin d'éviter les problèmes de surdosage et d'interaction médicamenteuse. Parmi ces plantes, Phyllanthus amarus Schum. & Thonn. (1827), communément appelée « Grenn anba fèy » [1], est connue pour ses nombreuses vertus notamment hépatoprotectrice, antidiabétique, antivirale (grippe), anti-inflammatoire, anti-cholestérol [2]. En Guadeloupe, cette plante est consommée par la population généralement fraîchement récoltée et la plupart du temps en infusion mais aussi sous forme de décoction aqueuse [3]. Aussi, les premiers travaux de recherche, réalisés en partenariat avec l'association APLAMEDAROM, ont pour but d'identifier les composés polaires de cette plante afin de mieux comprendre l'origine des propriétés observées. Ainsi, nous avons pu mettre en évidence de façon formelle, par Chromatographie en phase Liquide à Ultra Haute performance couplée à un spectromètre de masse, la présence de composés polyphénoliques bioactifs, notamment la phyllantine, la rutine et l'acide gallique. La phyllantine, caractéristique de l'espèce, est une lignane très active ayant une forte activité antioxydante, hépatoprotectrice et anticancéreuse [2]. La rutine est connue pour ses propriétés anti-oxydante et anti-hypertensive [2]. L'acide gallique se distingue par des propriétés anti-oxydante, anti-inflammatoire, antidiabétique, antivirale et anticancéreuse et a l'avantage d'être un composé biodisponible. De même, de nombreux composés jamais répertoriés à ce jour, dans cette espèce, ont également été mis en évidence et sont en cours de purification
Severe leukopenia in Staphylococcus aureus-necrotizing, community-acquired pneumonia: risk factors and impact on survival.
International audienceBACKGROUND: Necrotizing pneumonia attributed to Panton-Valentine leukocidin-positive Staphylococcus aureus has mainly been reported in otherwise healthy children and young adults, with a high mortality rate. Erythroderma, airway bleeding, and leukopenia have been shown to be predictive of mortality. The objectives of this study were to define the characteristics of patients with severe leukopenia at 48-h hospitalization and to update our data regarding mortality predicting factors in a larger population than we had previously described. METHODS: It was designed as a case-case study nested in a cohort study. A total of 148 cases of community-acquired, necrotizing pneumonia were included. The following data were collected: basic demographic information, medical history, signs and symptoms, radiological findings and laboratory results during the first 48 h of hospitalization. The study population was divided into 2 groups: (1) with severe leukopenia (leukocyte count ≤3,000 leukocytes/mL, n=62) and (2) without severe leukopenia (>3,000 leukocytes/mL, n=86). RESULTS: Median age was 22 years, and the male-to-female gender ratio was 1.5. The overall in-hospital mortality rate was 41.2%. Death occurred in 75.8% of severe leukopenia cases with median survival time of 4 days, and in 16.3% of cases with leukocyte count >3,000/mL (P<0.001). Multivariate analysis indicated that the factors associated with severe leukopenia were influenza-like illness (adjusted odds ratio (aOR) 4.45, 95% CI (95% confidence interval) 1.67-11.88, P=0.003), airway bleeding (aOR 4.53, 95% CI 1.85-11.13, P=0.001) and age over 30 years (aOR 2.69, 95% CI 1.08-6.68, P=0.033). A personal history of furuncles appeared to be protective (OR 0.11, 95% CI 0.01-0.96, P=0.046). CONCLUSION: S. aureus-necrotizing pneumonia is still an extremely severe disease in patients with severe leukopenia. Some factors could distinguish these patients, allowing better initial identification to initiate adapted, rapid administration of appropriate therapy
