The influence of urban park characteristics on bird diversity in Nanjing, China
Authors: Yang Xueru , Tan Xinwei , Chen Chuanwu , Wang Yanping 
Published: November 2020

Abstract
Background
Habitat loss, fragmentation and decrease of habitat quality caused by urbanization have led to a dramatic decline in biodiversity worldwide. For highly urbanized areas, parks have become “islands” or habitat fragments for wildlife. As an important indicator group of urban ecosystem health, the response of birds to urbanization has attracted the global attention of ecologists. Understanding the key factors affecting bird diversity in urbanized environment is crucial to the protection of biodiversity in urban ecosystems.

Methods
We used the line-transect method to survey birds in 37 urban parks in Nanjing, China. We also measured a number of park characteristics (area, isolation, shape index, environmental noise, distance to city center, and habitat diversity) that are commonly assumed to influence bird diversity. We then used the information-theoretic multi-model inference approach to determine which park characteristics had significant impacts on bird species richness.

Results
We found that park area, habitat diversity and the distance to city center were the best positive predictors of bird species richness in Nanjing urban parks. By contrast, park isolation, park shape and environmental noise had little or no influence on bird diversity.

Conclusions
Our study highlights the importance of park area, habitat diversity and the distance to city center in determining bird diversity in Nanjing city parks. Therefore, from a conservation viewpoint, we recommend that large parks with complex and diverse habitats far away from the city center should be retained or constructed to increase bird diversity in urban design and planning.
Die Interjektion boah in Alltagserzählungen:
Authors: Meiler Matthias , Huynh Ilham 
Published: November 2020

This paper examines conversational data of German everyday narratives in audiovisual footage of face-to-face encounters and in log files of Facebook’s instant messenger. The qualitative analysis is focused on the interjection boah as a means of narrative activity, paying special attention to its multimodal form and its media dependent functionality. The preliminary findings show that boah is used to signal to the communication partner the utterer’s noticing of something unexpected: be it an observed object or event, a communicative action, or a recalled memory. On a phonetical level, it is possible to distinguish two forms of boah: a marked form and an unmarked form. Which of these two forms is instantiated in interaction depends on the intensity of unexpectedness (or the enactment of unexpectedness). In everyday narratives, the marked form is often found to be expressed by the recipient. In contrast to the face-to-face data, our instant messenger data shows that, here, almost without exception boah is only used by the storyteller. This conspicuous finding can be explained by the specific temporality of instant messaging which results from the structural media conditions that instant messengers or e. g. internet relay chats similarly impose on the use of communicative means like interjections. We finally discuss how this dialectic relation between communicative function and mediality prompts further analyses of other communicative means, for example, the pattern of everyday narratives itself.

Published: November 2020

ZusammenfassungIn der heutigen Zeit werden alle Branchen auf Nachhaltigkeit eingestellt, so auch die Informatik. Hier werden drei Ziele verfolgt, welche zukünftig mithilfe der IT erreicht werden sollen. Diese sind der schonende Umgang mit begrenzten und wertvollen Ressourcen, das systematische Recycling von Altgeräten und eine sparsame Energiepolitik. Für diese wiederum gibt es verschiedene Ansätze. Ein Ansatz ist die Wiederaufbereitung von bereits gebrauchter Hardware mit dem Ziel die Nutzungsdauer von Geräten zu verlängern, um so die benötigten Rohstoffe länger im Nutzungskreislauf zu behalten. Am Beispiel von Laptops wird gezeigt, welche Faktoren die Kaufentscheidung von Käufern beeinflussen und wie sich die allgemeine Verteilung von Laptops in den Haushalten darstellt. Die Umfrage umfasst 870 Probanden, welche zu Ihrer Einstellung zum Thema Wiederaufbereitung und Nachhaltigkeit von Laptops befragt werden. Anhand der Ergebnisse soll aufgezeigt werden, welche Unterschiede zwischen verschiedenen Personengruppen im Hinblick auf die Akzeptanz von wiederaufbereiteten Laptops bestehen und wie stark der Einfluss des Nachhaltigkeitsaspektes bei der Entscheidung für wiederaufbereitete Geräte ist. Abschließend werden Handlungsempfehlungen für Maßnahmen zur Stärkung der Marktposition von wiederaufbereiteter Hardware vorgestellt.

Aim. To determine the relationship between the serum interleukin (IL) 18 level, the carriage of variant alleles IL18, IL18R1, IL18RAP and the risks of myocardial infarction (MI), hypertension, multifocal atherosclerosis in patients with stable coronary artery disease (CAD).Material and methods. Two hundred and sixty patients with stable coronary artery disease living in a large industrial region ofWestern Siberia were examined. Serum IL18 concentrations was determined by the enzyme immunoassay. Genotyping was performed by real-time polymerase chain reaction using TaqMan technology.Results. We revealed associations of rs13015714 IL18R1 and rs917997 IL18RAP sites with the MI risk (odds ratio (OR), 1,95 [95% confidence interval (CI), 1,063,58], p=0,029; OR, 2,01 [95% CI, 1,11-3,64], p=0,018, respectively). Associations of rs13015714 and rs917997 sites with high IL18 concentrations (genotypes C/T + T/T 488,0 [321,0, 687,2] pg/ml and T/G + G/G 504,2 [275,6; 655,5] pg/ml) was observed.Conclusion. The relationship between the minor alleles of rs13015714 IL18R1 and rs917997 IL18RAP sites with an increased risk of MI in patients with stable CAD was shown. Also, polymorphism at rs13015714 and rs917997 sites provides different levels of circulating IL18. In particular, the carriage of minor alleles is associated with increased IL-18 levels in patients with previous MI and multifocal atherosclerosis or hypertension, as well as with an increase in the risk of these pathologies.

Aim. Comparative analysis of the deoxyribonucleic acid (DNA) methylation level in the enhancer region of the CDKN2A/2B and CDKN2B-AS1 genes (9p21.3 locus) in vessels with/without atherosclerotic lesions, as well as in leukocytes of patients with clinically relevant carotid artery (CA) atherosclerosis and healthy individuals.Material and methods. The group of patients with clinically relevant atherosclerosis included 22 individuals with severe stenosis (>80%) of CA. Samples of atherosclerotic plaques, presenting CA regions, and great saphenous veins, as well as peripheral blood samples (leukocytes) were obtained from patients. The control group consisted of 14 individuals with the mild CA stenosis (£24%) and without hemodynamically relevant changes; peripheral blood samples were obtained from each of them. DNA methylation level was assessed by targeted bisulfite sequencing of amplicons.Results. The tissue-specific methylation of 31 CpG-site in the CDKN2A/2B and CDKN2B-AS1 gene enhancer was established: the vascular tissues significantly differed from the peripheral blood leukocytes. At the same time, there was an increase in the methylation level of both certain CpG sites and whole analyzed CA region affected by atherosclerosis (48,6 [34,8; 62,0]%), compared with intact vessels, both arteries (25,2 [23,1; 41,60]%, p=0,0001) and veins (35,0 [31,6; 40,0]%, p=0,0039). Patients had lower methylation levels in all CpG sites in blood leukocytes compared to blood vessel samples (8,7 [6,1; 9,7]%; p<0,05). At the same time, the level of DNA methylation in the blood leukocytes of atherosclerotic patients does not differ from that in healthy individuals (9,3 [8,3; 13,6]%; p>0,8).Conclusion. In the present study, the relationship between an increase in the DNA methylation in the enhancer of the CDKN2A/2B and CDKN2B-AS1 genes in CA and their atherosclerotic lesions was revealed, as well as the tissue-specific DNA methylation between vessels and peripheral blood leukocytes.

Published: November 2020

Javanese ethnic still upholds local wisdom including marriage customs. Traditional wedding ceremonies inherited from ancestors are still practiced up to present in the Boyolangu subdistrict, Tulungagung District, East Java Province. Traditional wedding ceremonies in this area are often carried out by utilizing plants during the procession, especially at the procession of temu manten. The use of plants in this procession is closely related to ethnobotany. Ethnobotany is an ecological discipline and the principle of the community's conception of local plants sources that can be used as a protector of cultural values. This research aims to find out the types of plants that are used as in the traditional wedding ceremonies and to provide an understanding of conservation of certain plants typically used for traditional wedding ceremonies. This research used quantitative descriptive design and applied a purposive sampling technique. It involved 10 respondents of community and 1 key informant (dukun manten or shaman). Based on the results of the study, the community in this area uses a total of 14 species of plants of 11 families at a traditional wedding ceremony. Commonly, the community utilizes the leaves and other parts of plants such as fruit, seeds, stems, and flowers. They are directly arranged in a certain way and used. The plants are obtained from around the yards of the community’s house

Abstract
Background: Endophytic actinomycetes, as emerging sources of bioactive metabolites, play a vital role in pharmaceutical development. Recent reports demonstrated that endophytic Streptomyces isolates could yield compounds with potent anticancer and antimicrobial properties that may be developed into chemotherapeutic drugs. Our study displayed that Streptomyces sp. LRE541 obtained from the root tissues of Lilium davidii var. unicolor Cotton, could be a potential source of anticarcinogens and antimicrobials.Results: Isolate LRE541 was characterized and identified as belonging to the genus Streptomyces based on the 16S rDNA sequence analysis, with highest sequence similarity to Streptomyces tauricus JCM4837T (98.81%). It produced extensively branched red substrate and vivid pink aerial hyphae that changed into amaranth, with elliptic spores sessile to the aerial mycelia. The secondary metabolites (EtOAc extract) produced by isolate LRE541 exhibited significant anticancer activities with IC50 values of 0.021, 0.2904, 1.484, 4.861, 6.986, 8.106, 10.87, 12.98, and 16.94 μg/mL against cancer cells RKO, 7901, HepG2, CAL-27, MCF-7, K562, Hela, SW1190 and A549, respectively, evaluated by the MTT assay. In contrast, the EtOAc extract showed less cytotoxicity activity against the normal human pulmonary artery endothelial cell (HPAEC) with an IC50 value of > 20 μg/mL than that of the cancer cells. To further explore the mechanism underlying the decrease in viability of cancer cells following the EtOAc extract treatment, cell apoptosis and cell cycle arrest assays were performed using two cancer cell lines, RKO and 7901. The result demonstrated that the EtOAc extract inhibited cell proliferation of RKO and 7901 cells by causing cell cycle arrest both at the S phase and inducing apoptosis in a dose‑dependent manner. Moreover, the EtOAc extract of isolate LRE541 with the concentrations within 100 μg/mL also possessed the antagonistic activities against E. coli ATCC 25922, MRSA ATCC 25923, P. aeruginosa and C. albicans ATCC 66415, and the antagonistic potent against the tested pathogens all displayed a dose-dependent manner. The UHPLC-MS/MS analysis of the EtOAc extract revealed that the presence of antitumor, potential antitumor and antimicrobial compounds could account for the potent antineoplasmic and antagonistic properties of the extract. Conclusion: This study provides the potential therapeutic applications of the bioactive metabolites from Streptomyces sp. LRE541 as novel antimicrobial and anticancer agents.

Abstract
Background: The knowledge of the key determinants of fertility desire among people living with HIV/AIDS is crucial for the design of efficient maternal and child health care programs. However, such determinants are not well understood in the context of a successful scale-up of antiretroviral therapy in Rwanda. The present study aim was to assess fertility desire among HIV- positive women and its determinants in Rwanda.Methods: Data were extracted from the 2015 Rwanda demographic health survey (RDHS) for 243 HIV-positive women of reproductive age. Univariate and multivariable based variable selection as well as multivariable logistic regression analysis were conducted. Results: The prevalence of desire to have another child in HIV-positive women was as high as 40.7%. Multivariable logistic regression analyses showed that the woman’s age, number of her living children, woman’s employment status, and having a co-wife are significant determinants of fertility desire among HIV- positive women in Rwanda. Women younger than 25 years, with no living child, who were unemployed or who had at least a co-wife were associated with greater odds of desire to have another child in the future than other HIV- positive women.. Conclusion: There is a need to devise integrated programs and services that are tailored to support HIV-positive women in planning their fertility, and controlling HIV transmission to their prospective children. Efficient policy and fertility interventions among WLHA in Rwanda should target young women, especially those living with partners and have fewer children than they prefer.
Enhanced Mechanical Property of RMI C/SiC Composites with Optimized Porous Carbon Structure by Heat Treatment

Published: November 2020

Abstract
C/SiC composites were fabricated by reactive melt infiltration (RMI) using porous C/C preforms as the skeleton, followed by the infiltration of molten silicon. A convenient technique of heat treatment in the range of 1500 to 2400 oC was applied to modify the porous carbon structure. The effects of heat treatment on the porous C/C preforms and the as-synthesized C/SiC composites were investigated in detail. The results show that the optimal porous carbon structure could be obtained after heat treatment at 1500 oC. After 1500 oC heat treatment, the median pore size and porosity of the porous C/C preform were 9.3 µm and 13.65% respectively, which were in favor of the subsequent infiltration of molten Si. The C/SiC composites with the optimized porous carbon structure showed a dense and uniform morphology without obvious cracks. Their bending strength could be up to 276 MPa, which was 28% higher than that of the C/SiC composites with untreated C/C preforms. However, with the increasing heat treatment temperature (2400 oC), the bending strength of the as obtained composites began to decrease because of the degradation of in-situ fiber strength. The optimized C/SiC composites exhibited a typical pseudo-plastic fracture behavior with obvious fiber pull-out. The improved mechanical property could be ascribed to the lower porosity of composites, the higher in-situ strength of fibers and the reduced matrix cracks.
