Barail Wildlife Sanctuary (BWS) lies amidst the tropical forests of the state Assam, India between the coordinates 24o58' – 25o5' North latitudes and 92o46' – 92o52' East longitudes. It covers an area of about 326.24 sq. km. with the altitude ranging from 100 – 1850 m. An ongoing study on the group Marchantiophyta (liverworts, bryophyta) of BWS reveals the presence of 42 species belonging to 24 genera and 14 families. Among these, one genus (Conocephalum Hill) and 13 species are recorded as new for the state of Assam, eight species have been found which are endemic to India, seven species are recorded as rare and one species, Heteroscyphus pandei S.C. Srivast. & Abha Srivast. as threatened within the study area. Out of 24 genera identified, 46% have been found growing purely as terrestrials, 25% as purely epiphytes and 29% have been found to grow both as terrestrials as well as epiphytes. Among these, a diverse and interesting range of microhabitats have also been observed for each taxon. It has been found that genera having vast range of microhabitats comprise large percentage of the total liverwort flora of BWS.
Ziel der Untersuchungen war die Dokumentation und Bewertung des derzeitigen Zustandes der Wildkrautflora von Getreideäckern einer typischen Mittelgebirgslandschaft sowie die Erprobung einer Methodik, mit der in angemessener Zeit größere Landschaftsausschnitte mit ausreichender Genauigkeit bearbeitet werden können. Die Wildkrautgesellschaften werden anhand der gültigen pflanzensoziologischen Typisierung beschrieben. In einem ca. 50 km2 großen Beispielsraum im Hunsrück südlich von Trier wurden über 400 Wintergetreideflächen im Frühjahr (April/Mai) und Sommer (Juni/Juli) des Jahres 2003 auf ihre Wildkrautflora hin untersucht. Durch gestaffeltes Gewichten der vorkommenden Wildkräuter nach ihrem Anteil an gefährdeten und allgemein selten werdenden Arten wurde jedem Wintergetreideschlag einer Ackerwildkrautwertklasse (3 Klassen) mit jeweils 3 Abstufungen zugeordnet. Das Vorkommen seltener Wildkräuter ist eng mit der Gesamtartenzahl und der Wildkrautdeckung insgesamt korreliert. Durch Herbizideinsatz in Herbst bzw. Frühjahr kann die floristische Ausstattung der Ackerschläge an den beiden Zeitpunkten voneinander abweichen, so dass eine Kombination beider Listen die Bewertung der Flächen besser absichert. Es ergaben sich keine gesicherten Unterschiede zwischen Artenreichtum und verschiedenen Feldfrüchten. Im Untersuchungsraum enthielten nur noch ca. 20 % der Wintergetreidefläche regelmäßig seltene bzw. viele unterschiedliche Arten, während 50 bis 65 % schon sehr an Arten verarmt sind. Die Gesamtartenzahl unserer Listen umfasst nur ca. 160 Arten, d. h., dass auch in für den Ackerbau ungünstigen Mittelgebirgsräumen die Wildkräuter stark an Vielfalt und Menge abgenommen haben.

L’Herbier de Strasbourg rassemble plusieurs dizaines de milliers de spécimens de Bryophytes dont la collection Nees von Esenbeck. A partir du "Lexikon deutschsprachiger Bryologen“ de J.P. Frahm et J. Eggers (2001) la liste de 199 bryologues ayant déposé des spécimens à Strasbourg (STR) est présentée, associée à une courte biographie et à l’origine géographique des récoltes botaniques.
Invasive treatment of NSTEMI patients in German chest pain units – evidence for a treatment paradox
(2018)
Background: Patients with non ST-segment elevation myocardial infarction (NSTEMI) represent the largest fraction of patients with acute coronary syndrome in German Chest Pain units. Recent evidence on early vs. selective percutaneous coronary intervention (PCI) is ambiguous with respect to effects on mortality, myocardial infarction (MI) and recurrent angina. With the present study we sought to investigate the prognostic impact of PCI and its timing in German Chest Pain Unit (CPU) NSTEMI patients.
Methods and results: Data from 1549 patients whose leading diagnosis was NSTEMI were retrieved from the German CPU registry for the interval between 3/2010 and 3/2014. Follow-up was available at median of 167 days after discharge. The patients were grouped into a higher (Group A) and lower risk group (Group B) according to GRACE score and additional criteria on admission. Group A had higher Killip classes, higher BNP levels, reduced EF and significant more triple vessel disease (p < 0.001). Surprisingly, patients in group A less frequently received early diagnostic catheterization and PCI. While conservative management did not affect prognosis in Group B, higher-risk CPU-NSTEMI patients without PCI had a significantly worse survival.
Conclusions: The present results reveal a substantial treatment gap in higher-risk NSTEMI patients in German Chest Pain Units. This treatment paradox may worsen prognosis in patients who could derive the largest benefit from early revascularization.
Objectives: Current knowledge on infections caused by Scedosporium spp. and Lomentospora prolificans in children is scarce. We therefore aim to provide an overview of risk groups, clinical manifestation and treatment strategies of these infections.
Methods: Pediatric patients (age ≤18 years) with proven/probable Scedosporium spp. or L. prolificans infection were identified in PubMed and the FungiScope® registry. Data on diagnosis, treatment and outcome were collected.
Results: Fifty-five children (median age 9 years [IQR: 5–14]) with invasive Scedosporium spp. (n = 33) or L. prolificans (n = 22) infection were identified between 1990 and 2019. Malignancy, trauma and near drowning were the most common risk factors. Infections were frequently disseminated. Most patients received systemic antifungal therapy, mainly voriconazole and amphotericin B, plus surgical treatment.
Overall, day 42 mortality was 31%, higher for L. prolificans (50%) compared to Scedosporium spp. (18%). L. prolificans infection was associated with a shorter median survival time compared to Scedosporium spp. (6 days [IQR: 3–28] versus 61 days [IQR: 16–148]). Treatment for malignancy and severe disseminated infection were associated with particularly poor outcome (HR 8.33 [95% CI 1.35–51.40] and HR 6.12 [95% CI 1.52–24.66], respectively). Voriconazole use at any time and surgery for antifungal treatment were associated with improved clinical outcome (HR 0.33 [95% CI 0.11–0.99] and HR 0.09 [95% CI 0.02–0.40], respectively).
Conclusions: Scedosporium spp. and L. prolificans infections in children are associated with high mortality despite comprehensive antifungal therapy. Voriconazole usage and surgical intervention are associated with successful outcome.
Non-indigenous species that become invasive are one of the main drivers of biodiversity loss worldwide. In various freshwater systems in Europe, populations of native amphipods and fish are progressively displaced by highly adaptive non-indigenous species that can perform explosive range extensions. A total of 40 Ponto-Caspian round gobies Neogobius melanostomus from the Rhine River near Düsseldorf, North Rhine-Westphalia, Germany, were examined for metazoan parasites and feeding ecology. Three metazoan parasite species were found: two Nematoda and one Acanthocephala. The two Nematoda, Raphidascaris acus and Paracuaria adunca, had a low prevalence of 2.5%. The Acanthocephala, Pomphorhynchus tereticollis, was the predominant parasite species, reaching a level of 90.0% prevalence in the larval stage, correlated with fish size. In addition, four invasive amphipod species, Corophium curvispinum (435 specimens), Dikerogammarus villosus (5,454), Echinogammarus trichiatus (2,695) and Orchestia cavimana (1,448) were trapped at the sampling site. Only D. villosus was infected with P. tereticollis at a prevalence of 0.04%. The invasive goby N. melanostomus mainly preys on these non-indigenous amphipods, and may have replaced native amphipods in the transmission of P. tereticollis into the vertebrate paratenic host. This study gives insight into a potential parasite-host system that consists mainly of invasive species, such as the Ponto-Caspian fish and amphipods in the Rhine. We discuss prospective distribution and migration pathways of non-indigenous vertebrate (round goby) and invertebrates (amphipods) under special consideration of parasite dispersal.
To a degree not widely recognized, some naturalized and invasive plants increase the risks to human health by enhancing the proliferation of vectors of virulent human parasites. These potential risks are restricted by neither ecosystem nor geography. The dense, floating mats of the tropical South American invasive macrophyte Eichhornia crassipes (water hyacinth) creates habitat for larvae of the dipteran vectors of Plasmodium spp., the causative agents of malaria, and other parasites. In Africa, the South American shrub Lantana camara (lantana) provides suitable habitat in otherwise treeless areas for dipteran vectors (Glossina spp.) of protozoans (Trypanosoma spp.) that cause trypanosomiasis. In the eastern United States, proliferation of the invasive Berberis thunbergii provides questing sites for the blacklegged ticks that carry the spirochete Borrelia burgdorferi, the causative agent of Lyme disease. Unanticipated health consequences will likely continue to emerge from new plant introductions. Hantaviruses are rodent-borne parasites that cause lethal hemorrhagic fevers in humans. Populations of rodent Hantavirus vectors in South America increase rapidly in response to fruit availability among masting, native bamboos. In the United States the omnivorous deer mouse Peromyscus maniculatus also carries Hantavirus (Sin Nombre Virus). The on-going escape of Asian frost-tolerant bamboos from cultivation raises the possibility of their becoming invaders - several have already become naturalized - and in turn providing a temporary food source for populations of infected native rodents. Proposed introductions of floating aquatic vascular species, species with masting reproduction and species that could occupy an unfilled niche in a new range deserve careful evaluation as catalysts of unintended species interactions, especially of human parasites.
