Chorioamnionitis secondary to Ureaplasma parvum infection: a case report
Authors: Moreno-Flores Antonio , Domínguez-Landesa María , Vázquez-López María Guadalupe , Sante-Fernández Laura 
Published: February 2023

Abstract

Objectives

Ureaplasma species are the most frequently isolated microorganisms in cases of spontaneous preterm labor, premature rupture of the membranes, or chorioamnionitis.

Case presentation
A woman at 28+6 weeks of gestation with no apparent history of interest presented at the hospital with contractions. Upon suspicion of chorioamnionitis, the patient was admitted for a low segment transverse cesarean section, which was completed without any complications. The patient was discharged at 7 days. The newborn remained stable and showed no clinical signs of infection. However, on suspicion of chorioamnionitis, empirical treatment with intravenous ampicillin (2 g every 6 h) and gentamicin (5 mg/kg once daily) was initiated. Samples of pharyngeal/tonsillar, ear, and anal/rectal exudates were collected. At 24 h, all samples were positive for Ureaplasma parvum. Empirical treatment was suspended, and treatment with intravenous azithromycin was initiated (12 mg once daily). Endocervical and placental exudates were also positive for U. parvum. Fifty-two days after birth, the newborn was discharged.

Conclusions
The relationship between Ureaplasma spp. colonization and perinatal disease seem to be clear. However, the high frequency of vaginal Ureaplasma spp. colonization and high rates of term labor among pregnant women with this colonization make further studies necessary.

Published: February 2023

Abstract
This study investigated the morphological diversity of arenicolous marine fungi (only those forming fruiting bodies on sand grains) at 11 sandy beaches in Taiwan. The species of Corollospora were identified by ascospore morphology and confirmed through a phylogenetic analysis of the 28S rDNA with other published sequences. The phylogenetic analysis revealed four previously unknown clades of Corollospora spp. related to C. portsaidica, while differences in ascospore morphology of the isolates in these four clades were observed. A total of 13 species of arenicolous marine fungi was identified from the 11 sandy beaches, including two Arenariomyces spp., nine Corollospora spp. (including four unknown Corollospora clades), Kohlmeyeriella crassa and Carbosphaerella cf sp. Taan Beach had the highest species richness (eight species), followed by Yongzhen Sea Park and Pisirian (five species each). The Shannon’s diversity index revealed the highest diversity at Taan Beach (1.51) over Pisirian (1.44), but the diversity was more even at the latter site (Pielou’s evenness index = 0.9) compared with the former (0.73). Non-metric multidimensional scaling suggests that there was generally a divide in the fungal community composition between the east and the west coasts of Taiwan.

Authors: Brenner Susanne C. , Gedicke Joscha , Sung Li-Yeng 
Published: February 2023

Abstract
We construct a symmetric interior penalty method for an elliptic distributed optimal control problem with pointwise state constraints on general polygonal domains.
The resulting discrete problems are quadratic programs with simple box constraints that can be solved efficiently by a primal-dual active set algorithm.
Both theoretical analysis and corroborating numerical results are presented.
Carbonate texture identification using multi-layer perceptron neural network

Published: February 2023

AbstractThis study proposes an approach to identifying carbonate rocks depositional texture utilizing more than 1250 thin-section photos as a data set from shallow-water carbonates of the Kruja zone (Albania). The proposed technique uses a numerical methodology based on digitized images of thin sections. According to the Dunham classification, it permits the user to recognize the carbonate texture automatically. The carbonate rock should not be affected by post-depositional processes. This technique uses as input gray-scale digital images taken from thin sections. Image processing can extract (as output) a set of 22 numerical parameters measured in the entire image, including white areas representing calcite cement. A multi-layer perceptron (MLP) neural network inputs these numerical parameters and produces, as output, the estimated depositional texture. We utilized 654 images of thin sections to evaluate this technique to train the neural network. We used 348 pictures taken from the same data set and 250 from the Burizana section (Kruja zone, Albania) to test the technique. The proposed method has shown 90.5 and 91.3% accuracy in identifying the automatically depositional texture using digitized images on the 348 and 250 test sets. Based on the good results obtained, this technique can be extending not only in identifying carbonate rocks texture but in every type of rock, getting fast and correct results. Python was used as a computer programming language for image processing and displaying images.
Anthropomorphic Motifs in Ancient Greek Ideas on the Origin of the Cosmos
Authors: Zelinová Zuzana , Škvrnda František 
Published: February 2023

Abstract
In our article, we will focus on an analysis of the relationship between man and the cosmos, set against the backdrop of ancient Greek ideas about the origin of the world. On the one hand, we will deal with the images of the creation of the world provided in Greek mythology and the religious tradition associated with it (in particular Hesiod); on the other hand, we will approach the anthropomorphic elements within the framework of philosophical cosmogonies (Plato’s dialogue, the Timaeus). Our aim is to show that Greek philosophical thought was never able to fully relinquish this anthropomorphism but nonetheless it did move away from a purely mythological tradition (as found in Hesiod and the pre-Socratics) and, in some measure towards a more scientific interpretation of the cosmos (as found in Plato).
Doing leadership in style: Pragmatic markers in New Zealand workplace interaction
Authors: Vine Bernadette , Holmes Janet 
Published: February 2023

AbstractThe Wellington Language in the Workplace Project (LWP) team has devoted considerable attention over the last few decades to researching workplace communication. We have focused especially on the insights that discourse analysis can provide regarding similarities and differences between the two major ethnic groups in New Zealand in “ways of doing things at work”. In this paper, we draw on both quantitative and qualitative analyses of interaction in Māori and Pākehā workplaces to demonstrate how these complementary approaches contribute to understanding different styles of leadership. Using Holmes’ concept of theculture orderand Connell’s concept of thegender order,we analyze the distribution and use of two specific pragmatic markers,ehandyou know.Ehis a distinctively New Zealand pragmatic marker whileyou knowhas been well-researched in English-speaking communities, providing rich contextual information on its functions. We examine the frequency of occurrence of each marker in both large formal meetings and smaller one-to-one interactions. We then analyze in more detail how these pragmatic markers contribute to one Māori male leader’s effective construction of a progressive, hybridized leadership identity, whilst also demonstrating the familiar double bind facing successful women leaders.
On commitment to untruthful implicatures
Authors: Meibauer Jörg 
Published: February 2023

AbstractIn the current debate on the lying-misleading distinction, many theorists distinguish between lying as insincere assertion and misleading through conveying an untruthful implicature. There is growing empirical evidence that average speakers count untruthful implicatures as cases of lying. What matters for them is the (degree) of commitment to an untruthful implicature. Since untruthful conversational implicatures may arise with non-assertions, and untruthful presuppositions are also judged as lying, a realistic conception of lying should aim at a definition of lying that it is able to cover these possibilities. Such a conception, which supports traditional assumptions about the semantics-pragmatics distinction, leads to a commitment-based definition of lying, as recently proposed by a number of authors.
lncRNA TPT1-AS1 promotes cell migration and invasion in esophageal squamous-cell carcinomas by regulating the miR-26a/HMGA1 axis
Authors: Cheng Wenhua , Yang Fang , Ma Yong 
Published: February 2023

Abstract
lncRNA TPT1-AS1 plays an oncogenic role in ovarian and cervical cancers. However, its involvement in the pathological progress of esophageal squamous-cell carcinomas (ESCCs) is unclear. lncRNA TPT1-AS1 was mainly localized in the cytoplasm of ESCC cells and interacted with miR-26a. In ESCC tissues, lncRNA TPT1-AS1 level was obviously increased, while miR-26a level was decreased. Interestingly, lncRNA TPT1-AS1 level was not significantly correlated with miR-26a level but was positively correlated with HMGA1 mRNA, a target of miR-26a. In ESCC cell lines KYSE510 and KYSE-30, lncRNA TPT1-AS1 overexpression enhanced HMGA1 expression, while it had no effect on miR-26a expression. Cell migration and proliferation assays indicated that lncRNA TPT1-AS1 and HMGA1 overexpression promoted ESCC cell migration and invasion, while their effects were alleviated by miR-26a overexpression. The migration and invasion of ESCC cells were suppressed by lncRNA TPT1-AS1 knockdown. In conclusion, lncRNA TPT1-AS1 plays an oncogenic role in ESCC and might function by upregulating HMGA1 via sponging miR-26a.
SIRT1/APE1 promotes the viability of gastric cancer cells by inhibiting p53 to suppress ferroptosis
Authors: Zhao Huijin , Ding Yuanyi , Zhang Lan 
Published: February 2023

Abstract
Gastric cancer (GC) is a common cancer worldwide with high mortality. Sirtuin 1 (SIRT1) and apurinic/apyrimidinic endodeoxyribonuclease 1 (APE1) are abnormally expressed in GC cells and related to p53, which is involved in ferroptosis. Thus, we explore the mechanism via which SIRT1, APE1, and p53 impact ferroptosis in GC cells. Specifically, GC cells were transfected with small-interfering RNA for SIRT1 (SiSIRT1) or small-interfering RNA for APE1 (SiAPE1) or with short-hairpin RNA for p53, and the cell viability, Fe2+, malondialdehyde (MDA), and glutathione (GSH) contents were detected by cell counting kit-8 assay and enzyme-linked immunosorbent assay. Western blot, immunofluorescence, and quantitative real-time polymerase chain reaction were conducted to quantify SIRT1, APE1, p53, solute carrier family 7 member 11 (SLC7A11), and glutathione peroxidase 4 (GPX4) levels in GC cells. Silencing of SIRT1 decreased viability, GSH content, and expressions of GPX4 and SLC7A11, while increased Fe2+, MDA content, and p53 expression in GC cells. Such aforementioned effects were reversed by APE1 overexpression. Also, SiAPE1 generated the same effects as SiSIRT1 on the above aspects, which was offset by p53 silencing. In short, SIRT1/APE1 promotes the growth of GC cells by targeting p53 to inhibit ferroptosis.
Glycoprotein non-metastatic melanoma B interacts with epidermal growth factor receptor to regulate neural stem cell survival and differentiation

Published: February 2023

Abstract
The functional recovery following spinal cord injury (SCI) remains a challenge clinically. Among the proteins interacted with the glycoprotein non-metastatic melanoma B (GPNMB), epidermal growth factor receptor (EGFR) during activation is able to promote the proliferation of neural stem cells (NSCs) in the spinal cord. We investigated the roles of GPNMB and EGFR in regulating the survival and differentiation of the NSCs. By overexpression and short-hairpin RNA-mediated knockdown of GPNMB in the NSCs, GPNMB promoted cell viability and differentiation by increasing the expressions of βIII tubulin and CNPase (2′,3′-cyclic nucleotide 3-phosphodiesterase). Using co-immunoprecipitation, we found that EGFR interacted with GPNMB. Furthermore, EGFR had a similar effect as GPNMB on promoting cell viability and differentiation. Overexpression of EGFR reversed the decrease in viability and differentiation caused by the knockdown of GPNMB, and vice versa. Last but not least, we tested the effect of GPNMB and EGFR on several intracellular pathways and found that GPNMB/EGFR modulated the phosphorylated (p)-c-Jun N-terminal kinase (JNK)1/2/JNK1/2 ratio and the p-nuclear factor κB (NF-κB p65)/NF-κB p65 ratio. In sum, our findings demonstrate the interaction between GPNMB and EGFR that regulates cell bioprocesses, with the hope to provide a new strategy of SCI therapy.

Traditional agri-food products and sustainability – A fruitful relationship for the development of rural areas in Portugal
Authors: Pato Maria Lúcia , Duque Ana Sofia 
Published: February 2023

Abstract
The protection of agri-food regional products is taking on growing importance in a market dominated by global companies and brands, often with no personality. Thirty years ago, the European Union (EU) agricultural product quality policy introduced the protection of geographical indications (GIs) for agricultural products and foodstuffs, with the aim of highlighting the quality of products resulting from a specific origin, therefore helping their communication and positioning in the market. This is important in countries with a considerable percentage of rural regions, as is the case of Portugal. Bearing this in mind, the purpose of this study is to see what are the drivers of the spatial distribution of traditional products (protected geographical indications, protected designations of origin, and traditional speciality guaranteed) in Portugal. For this purpose, the distribution of traditional products by regions and categories in Portugal will be presented. Also, Portugal’s position will be analysed and compared to the other EU countries, regarding the number of traditional products. Results show that Portugal is the country with the fourth biggest number of traditional certified products in EU territory. In the national territory, the Northern Region of Portugal has the biggest percentage of protected products, followed by Alentejo and the Centre Region of Portugal. Also, in Portugal, looking at the type of products, from a list of ten different categories of GIs, the ranking is dominated by (1) fresh meat, (2) meat products (cooked, salted, or smoked), and (3) cheese and milk-based products. If we consider that many of the aforementioned products are produced in less favoured regions, these results constitute an opportunity for their sustainable development. This benefits not only the producers, but also consumers who increasingly seek “authentic” and more natural products.
Zum Wasserstoffnarrativ und der diskursiven Rolle des Narrativs der Brückentechnologie – Ein empirisch gestützter Definitions-vorschlag
Authors: Meer Dorothee 
Published: February 2023

Abstract
In the last few years, usage of the term narrative has increased both in the media and in different scientific disciplines. This development has not been met with unanimous approval. In light of this and building on corpus studies of hydrogen, the following article introduces the term narrative and describes constructions that can be subsumed under narrative other than narrations in a narrower sense. At the same time, it is argued that this reading of the term narrative is suitably broad to be used for relevant developments in current mediated discourse.
Viele Vorschläge zur Güte
Authors: Sonntag Nico 
Published: February 2023

Zusammenfassung
Dieser Beitrag nimmt die von Strübing und Kollegen vorgeschlagenen Gütekriterien zum Anlass, deren Nutzen aus Sicht der analytisch-empirischen Soziologie sowie umgekehrt die Notwendigkeit analytisch-empirischer Gütekriterien für die qualitative Forschung zu diskutieren. Es werden zwei potentielle blinde Flecken der analytisch-empirischen Gütekontrolle besprochen. Erstens, die Möglichkeit der Theorieschöpfung aus einer reichhaltigen Empirie durch gegenstandsangemessene Methoden und der in der analytisch-empirischen Methodologie vernachlässigten Entstehungszusammenhang; zweitens, ein zu rigider Methodenbegriff. Die Fruchtbarkeit der Vorschläge von Strübing et al. wird hinsichtlich dieser Schwächen diskutiert. Obwohl hinsichtlich des ersten blinden Flecks Verbesserungspotential besteht, sind die Gütekriterien zu unbestimmt und zu speziell zugleich. Sie geben einerseits zu wenige Anhaltspunkte für systematische Methodenforschung und konkrete Gütebestimmung, enthalten andererseits in ihren Begründungen eine inhaltliche Festlegung auf bestimmte Methoden. Im zweiten Teil des Beitrags werden ausgewählte analytisch-empirische Gütekriterien diskutiert: 1) die Gütekriterien der Theoriebildung, 2) die interne und externe Validität sowie 3) Transparenz und Reproduzierbarkeit. Analytisch-empirische Gütekriterien beziehen sich auf alle Aspekte des Forschungsprozesses und nicht nur (wie behauptet) auf den engen Bereich der Messung. Die ausgewählten drei Anforderungsbereiche sind konkreten Methoden und auch einer Qualitativ-Quantitativ-Spaltung vorgelagert. Sie sollten daher in einem umfassenden Gütebegriff für die qualitative Forschung stärker berücksichtigt werden.
A Study on the Cementitious Mortars Containing Multi-walled Carbon Nanotubes and Nanographene
Authors: Pachideh Ghasem , Toufigh Vahab 
Published: February 2023

Abstract
In this paper, the effects of the multi-walled carbon nanotubes (MWCNTs) and nanographene (GP) on the mechanical performance of the cementitious mortars were investigated in different environments. Six mix designs were fabricated by considering the previous studies and exposed to potable water, acidic, and alkaline environments. The GP and MWCNTs partially replaced the cement with 0.25 %, 0.5 %, and 1 % of its weight. The standard mechanical tests, X-ray diffraction (XRD), and scanning electron microscope (SEM) analysis were performed on the specimens. The results indicated that including the MWCNTs and GP increases the compressive strength by 10 % and 20 % and similarly improves the tensile strength by nearly 15 % and 35 %, respectively. Additionally, despite the decrease in strength of the specimens because of exposure to aggressive environments, incorporation of the GP and MWCNTs enhanced the mechanical properties and microstructural characteristics of the mortars and improved their workability. Based on the XRD and SEM analysis results, the MWCNTs can fill in the pores better than the GP, leading to a greater integrity in the mortar’s structure and, thus, better improving the performance of the cementitious mortars.

Published: February 2023

Abstract
Pavement evaluation helps assess the structural and functional condition of roads. Traditional pavement evaluation methods cannot efficiently and accurately assess the state of road conditions at the network level. Though the pavement evaluation techniques based on high-resolution cameras and laser sensors assess the road conditions efficiently at traffic speeds, there are a few limitations in respect of automotive detection and quantification of pavement surface distress. Though artificial intelligence is a broad area, machine learning applications in highway engineering were proven to be successful. This paper presents the automated pavement distress classification using a convolutional neural network (NN) from the Keras library. VGG-16, the deep convolutional NN (DCNN) model, was deployed by necessary modification to get the desired output. The model is trained on a big data set of images with a wide range of pavement defects and irregularities. A DCNN classifier trained with an “Adam” optimizer was used to change the features of the NN to minimize the loss. As an output, the model classifies the pavement surface distresses as alligator cracks, longitudinal cracks, transverse cracks, pothole, and no crack portion of the pavement with maximum accuracy using a DCNN classifier.
