    Polycystic ovarian syndrome (PCOS) is one of the most common endocrine disorders. The aim of this study was to find the correlation between color Doppler ultrasound and serum tests as auxiliary diagnostic criteria in areas where there is no possibility of some tests. A total of 108 patients were enrolled. They were divided into three groups including patients with PCOS, patients with PCOA ultrasound, patients with ovaries and normal hormone tests. Transvaginal sonography was performed from three groups and the results were evaluated in gray scale. The volume of the ovary, the number of follicles and the placement of follicles were recorded using using Doppler spectrum of uterine artery and ovarian stroma. Their arterial resistance index was also calculated. In the next step, serum samples were evaluated to determine the level of LH, FSH, free testosterone, DHEAS and 17-OHP hormones in the early follicular phase. Gray scale ultrasonographic findings (volume and number of ovarian follicles) as well as LH values were higher in patients with PCOS than those in the other two groups. These results proved the reliability of using these factors in the prediction of PCOS. In this study, Doppler indexes did not correlate with the size of the ovaries, the number of ovarian follicles and the measured hormone levels. The findings of transvaginal ultrasound and investigating the relationship with clinical and laboratory outcomes, a more suitable pattern could be chosen for more accurate patient selection and, leading to timely treatment and reducing the complications of the disease. © 2019 The authors

    Birds as bio-indicators of environmental quality for flower pollinators, seed dispersal, and natural control of pests in nature, so they are ecologically important. Bird species play an important role both in the forest and those that can be found on the roadside. The purpose of this study was to determine the level of diversity and density of species on the roadside in the districts of Ende, Nagekeo and Timor Tengah Utara (TTU), Nusa Tenggara Timur Province. The method used in collecting bird data is point count. The results showed that the level of species diversity (H') was classified as moderate. The number of species found in all study areas is 55 species in 26 families. The species density in Ende Regency is 0.76 individuals/ha, Nagekeo 0.942 individuals/ha and TTU 0.098 individuals/ha. The evenness value (E) in the three study areas is more than 0.75, meaning that the community is stable for habitats that support the existence of bird species. The high similarity community (IS) in the districts of Ende and Nagekeo (69%) show that the two areas have almost the same species composition for their location on the same island on Flores Island. In contrast, it was found that Ende-TTU and Nagekeo-TTU had low community similarities because they were on two different islands. Protected bird species found during the research were the  white-bellied sea eagle  (Haliaeetus leucogaster), the asian woollyneck (Ciconia episcopus). Two other protected species found although not in the observation plots were the flores hawk-eagle (Nisaetus floris) and the spotted kestrel (Falco moluccensis). The exotic species found is sooty-headed bulbul (Pycnonotus aurigaster). Exotic species can be utilized for utilization activities that are economically as well as ecologically profitable

    Biome-specific effects of nitrogen and phosphorus on the photosynthetic characteristics of trees at a forest-savanna boundary in Cameroon

    Journal ArticleThe final publication is available at Springer via http://dx.doi.org/10.1007/s00442-015-3250-5Photosynthesis/nutrient relationships of proximally growing forest and savanna trees were determined in an ecotonal region of Cameroon (Africa). Although area-based foliar N concentrations were typically lower for savanna trees, there was no difference in photosynthetic rates between the two vegetation formation types. Opposite to N, area-based P concentrations were—on average—slightly lower for forest trees; a dependency of photosynthetic characteristics on foliar P was only evident for savanna trees. Thus savanna trees use N more efficiently than their forest counterparts, but only in the presence of relatively high foliar P. Along with some other recent studies, these results suggest that both N and P are important modulators of woody tropical plant photosynthetic capacities, influencing photosynthetic metabolism in different ways that are also biome specific. Attempts to find simple unifying equations to describe woody tropical vegetation photosynthesis-nutrient relationships are likely to meet with failure, with ecophysiological distinctions between forest and savanna requiring acknowledgement.Natural Environment Research Council (NERC) TROBIT consortiumRoyal Society - University Research Fellowshi

    Description Avec le vieillissement de la population, survient la dĂ©mence dans la population de personnes ĂągĂ©es. Objectif. L’objectif de cette Ă©tude Ă©tait d’estimer la prĂ©valence de cette affection dans une population de personnes ĂągĂ©es sĂ©nĂ©galaises. MĂ©thodes Par une Ă©tude transversale qui s’est dĂ©roulĂ©e du 01 mars 2004 au 31 dĂ©cembre 2005, des personnes ĂągĂ©es de 55 ans et plus venant consulter pour un problĂšme de santĂ© au Centre MĂ©dico-Social et Universitaire de l’IPRES (SĂ©nĂ©gal) ont Ă©tĂ© Ă©valuĂ©es sur le plan clinique et neuropsychologique. Des donnĂ©es sur les caractĂ©ristiques sociodĂ©mographiques, les antĂ©cĂ©dents mĂ©dico-chirurgicaux et familiaux, le mode de vie, le rĂ©seau social ont Ă©tĂ© collectĂ©es Ă  l’aide d’un questionnaire structurĂ© avec des rĂ©ponses fermĂ©es. RĂ©sultat La population Ă  l’étude Ă©tait composĂ©e de 872 personnes. Elles avaient un Ăąge moyen de 67,2 ans ± 7,5.Elles Ă©taient de sexe masculin (62,6%), mariĂ©es (79%), non instruites (50,7%). Dans les antĂ©cĂ©dents, l’HTA, le diabĂšte, les affections respiratoires, les affections rhumatismales, la cataracte et les troublesdigestifs Ă©taient les plus frĂ©quents. Le tabagisme et l’alcoolisme Ă©tait faible alors que la marche constituait la principale activitĂ© physique. Les personnes ĂągĂ©es vivaient en famille avec un bon rĂ©seau social.Cinquante huit (58) personnes ont prĂ©sentĂ© une dĂ©mence (6,6%). La prĂ©valence de la maladie variait de maniĂšre significative avec l’ñge et l’instruction. Conclusion Ce rĂ©sultat confirme que la prĂ©valence de la dĂ©mence varie en fonction de l’ñge et de l’instruction de la personne ĂągĂ©e

    Strange particle production in 158 and 40 AA GeV/cc Pb-Pb and p-Be collisions

    Full text link
    Results on strange particle production in Pb-Pb collisions at 158 and 40 AA GeV/cc beam momentum from the NA57 experiment at CERN SPS are presented. Particle yields and ratios are compared with those measured at RHIC. Strangeness enhancements with respect to p-Be reactions at the same beam momenta have been also measured: results about their dependence on centrality and collision energy are reported and discussed.Comment: Contribution to the proceedings of the "Hot Quarks 2004" Conference, July 18-24 2004, New Mexico, USA, submitted to Journal of Physics G 7 pages, 5 figure
