Authors: Aytekin Mehmet Ersin , Akyol Mustafa , Özkurt Berdan 
Published: January 2024

AbstractIn the current work, the effect of nano-sized Sn (50 nm)/Sr partial replacement on the superconducting properties such as crystal structure, quality of intra- and intergrain boundary coupling, dc electrical resistivity, and dc magnetization in the Bi-2212 ceramic superconductors were investigated. Ceramic superconductors with nominal composition of Bi2Sr2-x(Sn)xCa1Cu1.75Na0.25Oy where x = 0.25, 0.30, 0.35 and 0.40 were prepared by solid-state reaction method and characterized by powder X-ray diffraction (XRD), dc electrical resistivity, scanning electron microscopy (SEM) and magnetic hysteresis (M–H) measurements. Phase examination of by XRD indicated that the doping of x = 0.25 ratio nano-sized SnO2 to the strontium sites improved the formation of the Bi-2212 high-temperature superconducting phase. SEM micrographs showed that the morphological structure of all samples consisted of plate-like grains, which were separated from each other by grain boundaries, indicating the Bi-2212 superconducting phase. The highest superconductivity transition temperature among the samples was measured as the Tconset = 86 K at x = 0.25 in Bi2Sr2-x(Sn)xCa1Cu1.75Na0.25Oy. M–H loops of the Bi2Sr2-x(Sn)xCa1Cu1.75Na0.25Oy sample at x = 0.25 ratio is larger compared to other examples, indicating improvement intergrain connectivity as well as enhanced flux pinning centers. In addition, the critical current (Jc) values of the samples were calculated from M–H measurement using Bean’s critical current model. The best Jc values were obtained as 570 A/cm2 at 15 K, which is a relatively high value for BSCCO superconductors with polycrystalline structure.
5-Aminolevulinic acid treatment mitigates pesticide stress in bean seedlings by regulating stress-related gene expression and retrotransposon movements

Published: January 2024

AbstractOverdoses of pesticides lead to a decrease in the yield and quality of plants, such as beans. The unconscious use of deltamethrin, one of the synthetic insecticides, increases the amount of reactive oxygen species (ROS) by causing oxidative stress in plants. In this case, plants tolerate stress by activating the antioxidant defense mechanism and many genes. 5-Aminolevulinic acid (ALA) improves tolerance to stress by acting exogenously in low doses. There are many gene families that are effective in the regulation of this mechanism. In addition, one of the response mechanisms at the molecular level against environmental stressors in plants is retrotransposon movement. In this study, the expression levels of superoxide dismutase (SOD), ascorbate peroxidase (APX), catalase (CAT), glutathione reductase (GR), and stress-associated protein (SAP) genes were determined by Q-PCR in deltamethrin (0.5 ppm) and various doses (20, 40, and 80 mg/l) of ALA-treated bean seedlings. In addition, one of the response mechanisms at the molecular level against environmental stressors in plants is retrotransposon movement. It was determined that deltamethrin increased the expression of SOD (1.8-fold), GPX (1.4-fold), CAT (2.7-fold), and SAP (2.5-fold) genes, while 20 and 40 mg/l ALA gradually increased the expression of these genes at levels close to control, but 80 mg/l ALA increased the expression of these genes almost to the same level as deltamethrin (2.1-fold, 1.4-fold, 2.6-fold, and 2.6-fold in SOD, GPX, CAT, and SAP genes, respectively). In addition, retrotransposon-microsatellite amplified polymorphism (REMAP) was performed to determine the polymorphism caused by retrotransposon movements. While deltamethrin treatment has caused a decrease in genomic template stability (GTS) (27%), ALA treatments have prevented this decline. At doses of 20, 40, and 80 mg/L of ALA treatments, the GTS ratios were determined to be 96.8%, 74.6%, and 58.7%, respectively. Collectively, these findings demonstrated that ALA has the utility of alleviating pesticide stress effects on beans.

Zusammenfassung
Einleitung
Um die Häufigkeit von COVID-19-assoziierten (Coronavirus SARS-CoV-2-19) vaskulären Komplikationen bei COVID-19-Infektion in österreichischen gefäßchirurgischen Zentren zu ermitteln, haben wir im Namen der Österreichischen Gesellschaft für Gefäßchirurgie (ÖGG) eine Umfrage durchgeführt.

Methoden
16 Zentren wurden im Oktober 2022 eingeladen, an einer Online-Umfrage (SurveyMonkey®, Momentive Europe UC, Dublin, Irland) teilzunehmen (Rücklaufquote 75 % n = 12). Es wurden in der fachspezifischen Literatur berichtete vaskuläre Komplikationen bei Patienten und Patientinnen bei manifester COVID-19-Infektion oder nach kürzlicher COVID-19-Impfung abgefragt.

Ergebnisse
Zum Umfragezeitpunkt bestanden verpflichtende COVID-19-Testungen zum Zeitpunkt der Hospitalisierung (100 %) und häufige perioperative respiratorische Komplikationen und/oder Hyperkoagulabilität bei COVID-19-Patienten und Patientinnen. Vaskuläre Komplikationen im COVID-19-assoziierten Patientenkollektiv der Zentren waren akute Extremitätenischämien (92 %), Bypassverschlüsse (33 %), Viszeralarterienverschlüsse (58 %) sowie aortale- (33 %) und karotidale Thrombosen (17 %). Insgesamt 83 % der Zentren berichteten über verzögerte Wundbehandlungen als Folge der COVID-19-Maßnahmen mit resultierend vermehrt zu indizierenden Major- (67 %) und Minor-Amputationen (58 %) im Vergleich zu Vor-Covid-Zeit. Vaskuläre Komplikationen nach kürzlicher COVID-Impfung umfassten ausschließlich akute Extremitätenischämien (25 % der Zentren) und Bypassverschlüsse (17 %).
Schlussfolgerungen
Aufgrund häufiger postoperativer Komplikationen sollte lediglich bei dringlicher Indikation eine gefäßchirurgische OP/Intervention bei COVID-19-positiv getesteten Patienten und Patientinnen erfolgen. COVID-19-assoziierte arterielle Komplikationen sind je nach Lokalisation unterschiedlich häufig und komplex. Durch eine COVID-Impfung verursachte vaskuläre Komplikationen sind äußerst selten.

Role of GARP family transcription factors in the regulatory network for nitrogen and phosphorus acquisition
Authors: Ohama Naohiko , Yanagisawa Shuichi 
Published: January 2024

AbstractThe GARP (Golden2, ARR-B, Psr1) family proteins with a conserved DNA-binding domain, called the B-motif, are plant-specific transcription factors involved in the regulation of various physiological processes. The GARP family proteins are divided into members that function as monomeric transcription factors, and members that function as transcription factors in the dimeric form, owing to the presence of a coiled-coil dimerization domain. Recent studies revealed that the dimer-forming GARP family members, which are further divided into the PHR1 and NIGT1 subfamilies, play critical roles in the regulation of phosphorus (P) and nitrogen (N) acquisition. In this review, we present a general overview of the GARP family proteins and discuss how several members of the PHR1 and NIGT1 subfamilies are involved in the coordinated acquisition of P and N in response to changes in environmental nutrient conditions, while mainly focusing on the recent findings that enhance our knowledge of the roles of PHR1 and NIGT1 in phosphate starvation signaling and nitrate signaling.
Neues aus der hormonellen Kontrazeption
Authors: Schuchter S. , Zippl A. L. , Toth B. , Böttcher B. 
Published: January 2024

ZusammenfassungSeit Kurzem sind zwei neue orale Kontrazeptiva verfügbar, die beide kontinuierlich im 24/4-Schema eingenommen werden. Hierbei handelt es sich um das Gestagenmonopräparat mit dem Wirkstoff Drospirenon sowie das Kombinationspräparat mit den Wirkstoffen Estetrol und Drospirenon. Estetrol in Kombination mit Drospirenon weist eine vergleichbare kontrazeptive Sicherheit auf wie andere kombinierte orale Kontrazeptiva. Die antiandrogenen Gestagene Cyproteronacetat, Chlormadinonacetat und Nomegestrolacetat sind dosisabhängig mit einem erhöhten Meningeomrisiko assoziiert. Die kritische kumulative Dosis wird mit den gängigen oralen Kontrazeptiva erst nach mehreren Jahren erreicht, wobei sich der genaue Zeitraum aus den Hochrechnungen nicht ableiten lässt und für die drei Gestagene unterschiedlich sein könnte. Daher sollte die Verordnung nach Prüfung von Kontraindikationen und Aufklärung zurückhaltend erfolgen. Als Alternative kommen Kontrazeptiva mit anderen antiandrogen wirksamen Gestagenen wie Dienogest oder Drospirenon infrage.

Abstract
Introduction
Despite significant investments in collecting data on patient experience, it remains unclear whether the quality of healthcare has improved as a result. This study aimed to uncover the key factors shaping patient experience and evaluate the usefulness of free-text patient comments for guiding quality improvements in hospitals.

Methods
This study involved a secondary analysis of cross-sectional survey data by conducting a thematic analysis of patient feedback (using Net Promoter Score data) from a public hospital in Sydney, Australia.

Results
Analysis was conducted on 450 patient comments, collected over a 6-month period. The results identified three primary drivers of patient experience: (1) the provision of safe, timely, and effective treatment; (2) fostering human connections with caring and attentive staff, and (3) the provision of a comfortable and healing environment. Whilst the majority of comments were positive, these were often vague and non-specific. Negative comments, on the other hand, were found to be more specific and detailed, and therefore may be more useful for guiding quality improvement activities.

Conclusion
The research findings suggest that a range of factors influence patient experience, which can be grouped into the three interconnected themes. Based on these findings, a conceptual framework titled “The Three Pillars of Patient Experience” was developed to guide improvements in patient experience. The results of this study provide valuable insights into the factors that drive patient experience and demonstrate the usefulness of free-text patient comments for guiding healthcare quality improvements.

AbstractIn this paper, we analyze the hardness of the Matrix Code Equivalence () problem for matrix codes endowed with the rank metric, and provide the first algorithms for solving it. We do this by making a connection to another well-known equivalence problem from multivariate cryptography—the Isomorphism of Polynomials (). Under mild assumptions, we give tight reductions from to the homogenous version of the Quadratic Maps Linear Equivalence () problem, and vice versa. Furthermore, we present reductions to and from similar problems in the sum-rank metric, showing that is at the core of code equivalence problems. On the practical side, using birthday techniques known for , we present two algorithms: a probabilistic algorithm for running in time $$q^{\frac{2}{3}(n+m)}$$

Note on super-critical charged boson stars
Authors: Brihaye Yves , Hartmann Betti 
Published: January 2024

AbstractWe study the transition of charged boson stars from sub- to super-criticality. This transition is defined as that choice of coupling constants for which the Coulomb repulsion of two individual bosons (that make up the star) exactly cancels their gravitational attraction. It was recently shown that without self-interaction super-critical boson stars are unstable to decay into their individual constituents. Here we show that this is no longer true for the self-interacting case and that boson stars can possess spatial oscillations in the scalar field. We also discuss the corresponding black hole solutions that carry charged scalar hair.
Importance Weighting in Hybrid Iterative Ensemble Smoothers for Data Assimilation
Authors: Ba Yuming , Oliver Dean S. 
Published: January 2024

AbstractBecause it is generally impossible to completely characterize the uncertainty in complex model variables after assimilation of data, it is common to approximate the uncertainty by sampling from approximations of the posterior distribution for model variables. When minimization methods are used for the sampling, the weights on each of the samples depend on the magnitude of the data mismatch at the critical points and on the Jacobian of the transformation from the prior density to the sample proposal density. For standard iterative ensemble smoothers, the Jacobian is identical for all samples, and the weights depend only on the data mismatch. In this paper, a hybrid data assimilation method is proposed which makes it possible for each ensemble member to have a distinct Jacobian and for the approximation to the posterior density to be multimodal. For the proposed hybrid iterative ensemble smoother, it is necessary that a part of the mapping from the prior Gaussian random variable to the data be analytic. Examples might include analytic transformation from a latent Gaussian random variable to permeability followed by a black-box transformation from permeability to state variables in porous media flow, or a Gaussian hierarchical model for variables followed by a similar black-box transformation from permeability to state variables. In this paper, the application of weighting to both hybrid and standard iterative ensemble smoothers is investigated using a two-dimensional, two-phase flow problem in porous media with various degrees of nonlinearity. As expected, the weights in a standard iterative ensemble smoother become degenerate for problems with large amounts of data. In the examples, however, the weights for the hybrid iterative ensemble smoother were useful for improving forecast reliability.
Mobilising international embeddedness to resist radical policy change and dismantling: the case of Brazil under Jair Bolsonaro (2019–2022)
Authors: Trajber Waisbich Laura 
Published: January 2024

AbstractUnpacking the ‘crisis of democracy’ and what is means and does to policy processes is a new and ever-growing agenda. This paper uses the case of Brazil to examine bureaucratic responses, and attempted resistance, to democratic backsliding and policy dismantling in times of autocratisation, notably under Jair Bolsonaro (2019–2022). It does so by focusing on a less explored transnational lenses. It argues that the growing international embeddedness of Brazilian policies, including through policy transfer and technical cooperation initiatives mostly with other developing countries, has provided domestic sectoral bureaucracies and policy communities with additional strategic discursive and argumentative resources to mobilise, respond and try to resist policy dismantling at home.
The accuracy of field classifications for journals in Scopus
Authors: Thelwall Mike , Pinfield Stephen 
Published: January 2024

AbstractJournal field classifications in Scopus are used for citation-based indicators and by authors choosing appropriate journals to submit to. Whilst prior research has found that Scopus categories are occasionally misleading, it is not known how this varies for different journal types. In response, we assessed whether specialist, cross-field and general academic journals sometimes have publication practices that do not match their Scopus classifications. For this, we compared the Scopus narrow fields of journals with the fields that best fit their articles’ titles and abstracts. We also conducted qualitative follow-up to distinguish between Scopus classification errors and misleading journal aims. The results show sharp field differences in the extent to which both cross-field and apparently specialist journals publish articles that match their Scopus narrow fields, and the same for general journals. The results also suggest that a few journals have titles and aims that do not match their contents well, and that some large topics spread themselves across many relevant fields. Thus, the likelihood that a journal’s Scopus narrow fields reflect its contents varies substantially by field (although without systematic field trends) and some cross-field topics seem to cause difficulties in appropriately classifying relevant journals. These issues undermine citation-based indicators that rely on journal-level classification and may confuse scholars seeking publishing venues.

Published: January 2024

Abstract Genotype-environment interaction is pervasive in forest genetics. Delineation of spatial breeding zones (BZs) is fundamental for accommodating genotype-environment interaction. Here we developed a BZ classification pipeline for the forest tree Eucalyptus globulus in 2 Australian regions based on phenotypic, genomic, and pedigree data, as well on a detailed environmental characterization (“envirotyping”) and spatial mapping of BZs. First, the factor analytic method was used to model additive genetic variance and site–site genetic correlations (rB) in stem volume across 48 trials of 126,467 full-sib progeny from 2 separate breeding programs. Thirty-three trials were envirotyped using 145 environmental variables (EVs), involving soil and landscape (71), climate (73), and management (1) EVs. Next, sparse partial least squares-discriminant analysis was used to identify EVs that were required to predict classification of sites into 5 non-exclusive BZ classes based on rB. Finally, these BZs were spatially mapped across the West Australian and “Green Triangle” commercial estates by enviromic prediction using EVs for 80 locations and 15 sets of observed climate data to represent temporal variation. The factor analytic model explained 85.9% of estimated additive variance. Our environmental classification system produced within-zone mean rB between 0.76 and 0.84, which improves upon the existing values of 0.62 for Western Australia and 0.67 for Green Triangle as regional BZs. The delineation of 5 BZ classes provides a powerful framework for increasing genetic gain by matching genotypes to current and predicted future environments.
Is the trend toward a sustainable green synthesis of copper oxide nanoparticles completely safe for Oreochromis niloticus when compared to chemical ones?: using oxidative stress, bioaccumulation, and histological biomarkers
Authors: Badran Shereen R. , Hamed Aliaa 
Published: January 2024

AbstractScientists worldwide have noticed that cutting-edge technologies can be used to produce nanoparticles (NPs) in a sustainable and environmentally friendly way, instead of the old methods. However, the effectiveness of this approach for aquatic environments and species still needs to be determined. Therefore, this study aims to compare between the toxicity of green and chemically synthesized copper oxide nanoparticles (GS and CS) CuO NPs at two different concentrations on Nile tilapia (Oreochromis niloticus) using various biomarkers. CuO NPs’ formation was proved, and their different characterizations were recorded. Then, the fish samples were randomly allocated in glass aquaria into five groups: one acted as a control group, and the other groups were exposed to two concentrations (25 and 50 mg/L) of GS-CuO NPs and CS-CuO NPs, separately, for 4 days. After the experimental time, in all groups that were exposed to two concentrations of both synthesized CuO NPs, the results revealed that glutathione peroxidase (GPx), catalase (CAT), superoxide dismutase (SOD), and thiobarbituric acid reactive substances (TBARS) levels were elevated in the liver and gills compared to glutathione reduced (GSH) content, which showed a significant decline. Bioaccumulation of Cu was more prevalent in the liver than in the gills, and the highest bioaccumulation capacity was more evident in the groups exposed to CS-CuO NPs. Moreover, the bioaccumulation of Cu caused severe histological changes in the liver and gills. In conclusion, the results suggested that GS-CuO NPs revealed less toxicity than CS-CuO NPs to the examined fish. However, they are still toxic, and their toxic effect cannot be overlooked.
SF-6D Normative Values Among Patients Undergoing Bariatric Surgery: Results Based on Real-World Evidence from the Scandinavian Obesity Surgery Registry (SOReg)
Authors: Sun Sun , Stenberg Erik , Luo Nan , Franklin Karl A. , Lindholm Lars , Salén Klas-Göran , Cao Yang 
Published: January 2024

Abstract
Background
The SF-6D index can be used to calculate quality-adjusted life years in economic evaluations, which is required by reimbursement agencies and national advisory bodies, including the Swedish ones. However, despite that SF-36 has been largely applied among patients undergoing bariatric surgery, almost no study has accessed the short form six-dimensions (SF-6D) after bariatric surgery.

Aim
To establish normative values for the SF-6D index among patients undergoing bariatric surgery.

Materials and Methods
All patients who received bariatric surgery in Sweden between 2011–01-01 and 2019–03-31 were obtained from the Scandinavian Obesity Surgery Registry (SOReg). Information includes patients’ sociodemographic characteristics, details regarding the procedure, and postsurgical conditions. The SF-36 is applied at baseline and at follow-up years 1, 2, and 5. The multiple sequential imputation method was applied to handle missingness on SF-6D items. Based on the UK tariff, the SF-6D preference scores were calculated. The normative values for the mean (SD) SF-6D index were reported by timepoint and surgical complications for men and women, respectively. Multivariate analyses were applied to investigate how the SF-6D index is associated with timepoint, controlling for age, sex, BMI, and comorbidities in a stepwise manner.

Results
The SF-6D index increased at 1 year relative to baseline and was roughly maintained at the same level at 2 years. The normative value of the SF-6D index can be used in economic evaluations for bariatric surgery.
