Cylindrocladiella parva as a causal agent of dieback on Euonymus fortunei

Im August 2011 traten an Euonymus fortunei Absterbe­erscheinungen unbekannter Ursache auf. Aus befallenen Trieben wurde ein Cylindrocladium-ähnlicher Pilz isoliert. Anhand seiner morphologischen Merkmale wurde der Pilz als Cylindrocladiella parva (P.J. Anderson) Boesewinkel identifiziert. Eine anschließende Sequenzanalyse der ITS-Region sowie des β-Tubulin-Gens bestätigte das Ergebnis. Die Pathogenität des Pilzes an E. fortunei 'Emerald’n Gold' wurde in mehreren Versuchsansätzen geprüft. Nach Inokulation an den Nodien nach leichter Verletzung entwickelten sich bei hoher Luftfeuchte innerhalb von sieben Wochen an zweijährigen Pflanzen deut­liche Krankheitssymptome. Cylindrocladiella parva ließ sich aus befallenen Trieben reisolieren. Die Pathogenität dieses Erregers an E. fortunei ist damit nachgewiesen. Es ist das erste bekannt gewordene Auftreten von Cylindro­cladiella parva an E. fortunei in Deutschland. DOI: 10.5073/JfK.2014.01.01, https://doi.org/10.5073/JfK.2014.01.01In August 2011 a shoot dieback of unknown cause was observed on Euonymus fortunei. From the affected shoots a fungus similar to Cylindrocladium was isolated. According to its morphological characteristics this fungus could be identified as Cylindrocladiella parva (P.J. Anderson) Boesewinkel. The subsequent sequence analysis of the ITS regions as well as the β-tubulin-gene confirmed this result. Pathogenicity of this fungus was tested in several trials on E. fortunei 'Emerald’n Gold'. After inoculation of wounded nodes with the fungus and incubation with high humidity two year old plants developed disease symptoms within seven weeks. Cylindrocladiella parva could be reisolated from infected shoots. This is the first occurrence of Cylindrocladiella parva on E. fortunei in Germany according to our knowledge.

Mesenchymal stromal cells for treatment of steroid-refractory GvHD : a review of the literature and two pediatric cases

Severe acute graft versus host disease (GvHD) is a life-threatening complication after allogeneic hematopoietic stem cell transplantation. Human mesenchymal stromal cells (MSCs) play an important role in endogenous tissue repair and possess strong immune-modulatory properties making them a promising tool for the treatment of steroid-refractory GvHD. To date, a few reports exist on the use of MSCs in treatment of GvHD in children indicating that children tend to respond better than adults, albeit with heterogeneous results. We here present a review of the literature and the clinical course of two instructive pediatric patients with acute steroid-refractory GvHD after haploidentical stem cell transplantation, which exemplify the beneficial effects of third-party transplanted MSCs in treatment of acute steroid-refractory GvHD. Moreover, we provide a meta-analysis of clinical studies addressing the outcome of patients with steroid-refractory GvHD and treatment with MSCs in adults and in children (n = 183; 122 adults, 61 children). Our meta-analysis demonstrates that the overall response-rate is high (73.8%) and confirms, for the first time, that children indeed respond better to treatment of GvHD with MSCs than adults (complete response 57.4% vs. 45.1%, respectively). These data emphasize the significance of this therapeutic approach especially in children and indicate that future prospective studies are needed to assess the reasons for the observed differential response-rates in pediatric and adult patients.

Sensing river and floodplain biodiversity : developing a prototype

Freshwaters, such as rivers and floodplains, are among the world’s most diverse ecosystems, but they are losing biodiversity faster than any other ecosystem, mainly due to human activities. A major problem is the low awareness of biodiversity loss. Triggering emotions and amazement may increase people’s biodiversity perception in a more holistic way. Therefore, with an immersive audio visual VR-simulation prototype based on 3D point clouds and sound recordings above and below water developed in the Unity game engine, we want to allow for sensing river biodiversity. Feedback from a user study demonstrates that the prototype can promote laypersons’ awareness of biodiversity loss and provides insights for its further enhancement

Basics of collaborative research data management: Requirements for a Schleswig-Holstein state initiative on research data management

Das Papier "Grundlagen eines partnerschaftlichen Forschungsdatenmanagements - Anforderungen an eine schleswig-holsteinische Landesinitiative zum Forschungsdatenmanagement" umreißt die Anforderungen für eine schleswig-holsteinische Landesinitiative zum Forschungsdatenmanagement (FDM-SH). Hierfür wird zunächst das Umfeld, in dem eine solche Initiative entstehen und agieren soll, beschrieben. So beeinflussen sowohl die Eigenheiten der regionalen Forschungslandschaft wie auch die Entwicklungen im Bereich der Nationalen Forschungsdateninfrastruktur (NFDI) die Ausprägungen von Landesinitiativen. Die speziellen Anforderungen werden durch den Vergleich mit anderen Landesinitiativen, die Analyse von spezifischen Umfrageergebnissen aus Schleswig-Holstein sowie die Berücksichtigung der Anforderungen der NFDI gesammelt. Der Ansatz des partnerschaftlichen Forschungsdatenmanagements (FDM) spiegelt das Anliegen Schleswig-Holsteins wider, die Herausforderungen für ein zeitgemäßes FDM vor Ort gemeinsam zu bewältigen und dabei sowohl Know-how zu teilen als auch Ressourcen zu schonen

New genetic loci link adipose and insulin biology to body fat distribution.

Body fat distribution is a heritable trait and a well-established predictor of adverse metabolic outcomes, independent of overall adiposity. To increase our understanding of the genetic basis of body fat distribution and its molecular links to cardiometabolic traits, here we conduct genome-wide association meta-analyses of traits related to waist and hip circumferences in up to 224,459 individuals. We identify 49 loci (33 new) associated with waist-to-hip ratio adjusted for body mass index (BMI), and an additional 19 loci newly associated with related waist and hip circumference measures (P < 5 × 10(-8)). In total, 20 of the 49 waist-to-hip ratio adjusted for BMI loci show significant sexual dimorphism, 19 of which display a stronger effect in women. The identified loci were enriched for genes expressed in adipose tissue and for putative regulatory elements in adipocytes. Pathway analyses implicated adipogenesis, angiogenesis, transcriptional regulation and insulin resistance as processes affecting fat distribution, providing insight into potential pathophysiological mechanisms

Worldwide trends in hypertension prevalence and progress in treatment and control from 1990 to 2019: a pooled analysis of 1201 population-representative studies with 104 million participants

Background Hypertension can be detected at the primary health-care level and low-cost treatments can effectively control hypertension. We aimed to measure the prevalence of hypertension and progress in its detection, treatment, and control from 1990 to 2019 for 200 countries and territories. Methods We used data from 1990 to 2019 on people aged 30–79 years from population-representative studies with measurement of blood pressure and data on blood pressure treatment. We defined hypertension as having systolic blood pressure 140 mm Hg or greater, diastolic blood pressure 90 mm Hg or greater, or taking medication for hypertension. We applied a Bayesian hierarchical model to estimate the prevalence of hypertension and the proportion of people with hypertension who had a previous diagnosis (detection), who were taking medication for hypertension (treatment), and whose hypertension was controlled to below 140/90 mm Hg (control). The model allowed for trends over time to be non-linear and to vary by age. Findings The number of people aged 30–79 years with hypertension doubled from 1990 to 2019, from 331 (95% credible interval 306–359) million women and 317 (292–344) million men in 1990 to 626 (584–668) million women and 652 (604–698) million men in 2019, despite stable global age-standardised prevalence. In 2019, age-standardised hypertension prevalence was lowest in Canada and Peru for both men and women; in Taiwan, South Korea, Japan, and some countries in western Europe including Switzerland, Spain, and the UK for women; and in several low-income and middle-income countries such as Eritrea, Bangladesh, Ethiopia, and Solomon Islands for men. Hypertension prevalence surpassed 50% for women in two countries and men in nine countries, in central and eastern Europe, central Asia, Oceania, and Latin America. Globally, 59% (55–62) of women and 49% (46–52) of men with hypertension reported a previous diagnosis of hypertension in 2019, and 47% (43–51) of women and 38% (35–41) of men were treated. Control rates among people with hypertension in 2019 were 23% (20–27) for women and 18% (16–21) for men. In 2019, treatment and control rates were highest in South Korea, Canada, and Iceland (treatment >70%; control >50%), followed by the USA, Costa Rica, Germany, Portugal, and Taiwan. Treatment rates were less than 25% for women and less than 20% for men in Nepal, Indonesia, and some countries in sub-Saharan Africa and Oceania. Control rates were below 10% for women and men in these countries and for men in some countries in north Africa, central and south Asia, and eastern Europe. Treatment and control rates have improved in most countries since 1990, but we found little change in most countries in sub-Saharan Africa and Oceania. Improvements were largest in high-income countries, central Europe, and some upper-middle-income and recently high-income countries including Costa Rica, Taiwan, Kazakhstan, South Africa, Brazil, Chile, Turkey, and Iran. Interpretation Improvements in the detection, treatment, and control of hypertension have varied substantially across countries, with some middle-income countries now outperforming most high-income nations. The dual approach of reducing hypertension prevalence through primary prevention and enhancing its treatment and control is achievable not only in high-income countries but also in low-income and middle-income settings

Heterogeneous contributions of change in population distribution of body mass index to change in obesity and underweight NCD Risk Factor Collaboration (NCD-RisC)

From 1985 to 2016, the prevalence of underweight decreased, and that of obesity and severe obesity increased, in most regions, with significant variation in the magnitude of these changes across regions. We investigated how much change in mean body mass index (BMI) explains changes in the prevalence of underweight, obesity, and severe obesity in different regions using data from 2896 population-based studies with 187 million participants. Changes in the prevalence of underweight and total obesity, and to a lesser extent severe obesity, are largely driven by shifts in the distribution of BMI, with smaller contributions from changes in the shape of the distribution. In East and Southeast Asia and sub-Saharan Africa, the underweight tail of the BMI distribution was left behind as the distribution shifted. There is a need for policies that address all forms of malnutrition by making healthy foods accessible and affordable, while restricting unhealthy foods through fiscal and regulatory restrictions

Insights into the direct anti-influenza virus mode of action of Rhodiola rosea

Background: The anti-influenza A virus activities and contents of previously isolated most active flavonoids (rhodiosin and tricin) from a standardized hydro-ethanolic R. rosea root and rhizome extract (SHR-5®), did not fully explain the efficacy of SHR-5®. Moreover, the mode of antiviral action of SHR-5® is unknown. Purpose: To determine the anti-influenza viral principle of SHR-5® we evaluated i) the combined anti-influenza virus effect of rhodiosin and tricin, ii) the impact of its tannin-enriched fraction (TE), iii) its antiviral spectrum and mode of action, and iv) its propensity for resistance development in vitro. Methods: The combined anti-influenza virus effect of rhodiosin and tricin and the impact of TE were investigated with cytopathic effect (CPE)-inhibition assays in MDCK cells. A tannin-depleted fraction (TD) and TE were prepared by polyamide column chromatography and dereplicated by LC-MS. Plaque-reduction assays provided insights into the anti-influenza virus profile, the mode of action, and the propensity for resistance development of SHR-5®. Results: Our results i) did not reveal synergistic anti-influenza A virus effects of rhodiosin and tricin, but ii) proved a strong impact of TE mainly composed of prodelphinidin gallate oligomers. iii) TE inhibited the plaque-production of influenza virus A(H1N1)pdm09, A(H3N2), and B (Victoria and Yamagata) isolates (including isolates resistant to neuraminidase and/or M2 ion channel inhibitors) with 50% inhibitory concentration values between 0.12 - 0.53 µg/ml similar to SHR-5®. Mechanistic studies proved a virucidal activity, inhibition of viral adsorption, viral neuraminidase activity, and virus spread by SHR-5® and TE. iv) No resistance development was observed in vitro. Conclusion: For the first time a comprehensive analysis of the anti-influenza virus profile of a hydro-ethanolic R. rosea extract (SHR-5®) was assessed in vitro. The results demonstrating broad-spectrum multiple direct anti-influenza virus activities, and a lack of resistance development to SHR-5® together with its known augmentation of host defense, support its potential role as an adaptogen against influenza virus infection

Historic Timber Roof Structure Reconstruction through Automated Analysis of Point Clouds

We present a set of methods to improve the automation of the parametric 3D modeling of historic roof structures using terrestrial laser scanning (TLS) point clouds. The final product of the TLS point clouds consist of 3D representation of all objects, which were visible during the scanning, including structural elements, wooden walking ways and rails, roof cover and the ground; thus, a new method was applied to detect and exclude the roof cover points. On the interior roof points, a region-growing segmentation-based beam side face searching approach was extended with an additional method that splits complex segments into linear sub-segments. The presented workflow was conducted on an entire historic roof structure. The main target is to increase the automation of the modeling in the context of completeness. The number of manually counted beams served as reference to define a completeness ratio for results of automatically modeling beams. The analysis shows that this approach could increase the quantitative completeness of the full automatically generated 3D model of the roof structure from 29% to 63%
