Conceptualizations of Abandoned Mine Land Reclamation: A Case Study of the Daniel Boone National Forest
Authors: Caudill Hannah , Baka Jennifer
Published: June 2024

abstract: The Daniel Boone National Forest (DBNF) contains numerous abandoned mine sites left over from eastern Kentucky's history of coal mining, many of which are leaching contaminants into the environment. The United States Forest Service is acting to reclaim these sites to mitigate negative impacts. There are several other governmental and non-governmental actors in Appalachia with different conceptualizations of reclamation's purpose. This research examines the mine land reclamation process on a protected area within a region with a history of resource extraction and builds on previous work to understand different conceptualizations of abandoned mine land reclamation in Appalachia. Content analysis was conducted on DBNF project documentation, interviews, and documentation from state and federal agencies, and NGOs. These documents indicate that government entities tend to conceptualize reclamation and its purpose in a siloed manner. This research also reveals that non-governmental actors tend to conceptualize reclamation in a holistic manner but are less able to exert control over an area. The DBNF largely conceptualizes the purpose of reclamation as achieving ecosystem restoration but may benefit from working more closely with NGOs and adopting a similarly holistic approach. Opening a dialogue between these actors could help address the knowledge gap present at the DBNF's sites.
Community-Led Growth als Markteintrittsstrategie für Software-Startups im B2B-Umfeld
Authors: Grimm Ramona , Durst Carolin
Published: June 2024

Community-gesteuerte Marketing- und Vertriebsaktivitäten nehmen seit dem Pandemiejahr stetig zu und etablieren sich in den USA bereits als vielversprechende Markteintrittsstrategie für Software-Startups. Innerhalb der Entrepreneurial Marketing Forschung ist der Ansatz bislang wenig diskutiert, birgt aber großes Potenzial wertschöpfende Interaktionen mit Nutzern und Kunden zu generieren, indem frühzeitig eine Community aufgebaut wird. Mit dem Community-Led Growth Ansatz können insbesondere Herausforderungen von Software-Startups im B2B-Umfeld adressiert werden. Da die Kundenakquise hier besonders langwierig und komplex ist, kann mithilfe einer Community eine kundenzentrierte Produktentwicklung mit vielen direkten Berührungspunkten fokussiert werden. Somit können Markteintrittsbarrieren reduziert, Expertise und Kredibilität aufgebaut und erste Kontakte zu potenziellen Kunden oder späteren Vertriebskanälen und Multiplikatoren geknüpft werden. Dieser Artikel liefert einen konzeptionellen Beitrag zu Community-Led Growth und reflektiert, wie die Dynamik von Communities entlang der Customer Journey Wert für Unternehmen wie z. B. geringere Servicekosten oder eine stärkere Produktaffinität und daraus resultierend eine stärkere Kundenzufriedenheit und -bindung schaffen kann. Basierend auf dem Orbit Model und dem Community Grid wird zunächst aufgezeigt, wie Community-Mitglieder segmentiert werden können und wer zum initialen Kern einer Community gehört. Ein Vergleich von drei Modellen zum Aufbau von Communities (Community Canvas, Community-Led Growth Model und Community Experience) zeigt auf, welche internen und externen Voraussetzungen für den Aufbau einer Community notwendig sind. Abschließend werden auf Basis einer Minimum Viable Community Canvas Handlungsempfehlungen für Software-Startups abgeleitet und ein erweitertes Framework mit iterativen und zielorientierten Komponenten skizziert.

Understanding how young people transitioning from out-of-home care acquire and develop independent living skills and knowledge: A systematic review of longitudinal studies
Authors: Starr Michael , Cordier Reinie , Pakpahan Eduwin , Robinson Matthew , Speyer Renée , Chung Donna
Published: June 2024

Young people leaving state care often experience hardship in many areas of their life. At a population level, their outcomes in early adulthood are poorer compared to general populations. Effective preparation for leaving care and post-care support systems is vital to improving outcomes. Individual and systemic support for young people to acquire Independent Living Skills (ILS) in the following eight ILS domains have been identified: Financial Management, Knowledge of Accessing Available Supports, Managing Housing, Education Planning, Job Seeking, Health Risk Management, Domestic and Self-help Task, and Managing Relationships. This systematic review aims to identify, summarise, and appraise longitudinal studies that address ILS across these ILS domains to understand better how outcomes could be improved. Seven databases (CINAHL, Embase, ProQuest, PsychINFO, PubMed, Scopus, and Web of Science) were searched on 20th July 2023. In total, twenty-seven studies published between 1994 and 2022 from various countries met the eligibility criteria. The included studies reported on 2–4 waves and adopted different methodological approaches. Study quality was scored using Qualsyst. Study characteristics and details of the interventions are presented in tables. Studies cover overlapping ILS domains, which are mapped in a matrix. Results revealed that nearly three-quarters (74% or 20 out of 27) of studies explored four or fewer of the eight ILS domains. The most frequent ILS domain covered was ‘Knowledge of Accessing Available Supports’ (19/27 studies). The main conclusion considers the concept of independence as a misnomer, with ILS covering multiple, intersecting, and interdependent domains, which ultimately help and hinder one another. Further research is required to adopt a more comprehensive approach encompassing all the domains to better inform policy, programs, and practice. A limitation is that a meta-analysis was not conducted for this review. This study registered a ‘Protocol’ with OSF Registries (DOI: 10.17605/OSF.IO/MJ3ZX) on June 5th, 2022.
Evaluation of cytokine expressions in patients with recurrent aphthous stomatitis: A systematic review and meta-analysis
Authors: Teng Fangjun , Jin Qiuchen
Published: June 2024

This systematic review and meta-analysis aimed to evaluate the expression levels of various T helper (Th) cell-secreted cytokines in recurrent aphthous stomatitis (RAS). Case-control studies comparing the serum or salivary levels of cytokines between RAS patients and healthy controls were searched in PubMed, EMBASE, Web of Science, and Google Scholar prior to September 30, 2023. Cytokines produced by Th1 (interleukin [IL]-1, IL-2, IL-8, IL-12, tumor necrosis factor alpha [TNF-α], interferon gamma [IFN-γ]), Th2 (IL-4, IL-5, IL-6, IL-10, IL-13), and Th17 (IL-17A) cells were investigated. The standard mean difference (SMD) with 95% confidence interval (CI) was calculated to detect the difference. A total of 20 studies comprising 1070 RAS patients and 536 healthy controls were included. RAS patients had significantly higher salivary levels of IL-2 (SMD = 4.15, 95%CI 0.83–7.48), IL-5 (SMD = 0.53, 95%CI 0.05–1.00), IL-6 (SMD = 0.48, 95%CI 0.12–0.84), IL-12 (SMD = 0.94, 95%CI 0.18–1.71), and TNF-α (SMD = 1.31, 95%CI 0.44–2.18) compared to healthy controls. Serum levels of IL-6 (SMD = 0.48, 95%CI 0.30–0.66), TNF-α (SMD = 0.70, 95%CI 0.22–1.17), and IFN-γ (SMD = 0.72, 95%CI 0.17–1.28) were significantly increased, while serum IL-10 levels (SMD = -2.25, 95%CI -3.99 to -0.52) were reduced in RAS patients. Patients diagnosed with major RAS had markedly elevated serum IL-8 levels (SMD = 0.39, 95%CI 0.07–0.71) and a trend toward higher serum IL-6 levels (SMD = 0.51, 95%CI -0.02 to 1.04) than those with minor RAS. In conclusion, Th1/Th2-related cytokines, especially IL-2, IL-6, and TNF-α, are involved in the pathogenesis of RAS development and progression and are potential therapeutic targets for RAS.
Enhancing stock volatility prediction with the AO-GARCH-MIDAS model
Authors: Liu Ting , Choo Weichong , Tunde Matemilola Bolaji , Wan Cheongkin , Liang Yifan
Published: June 2024

Research has substantiated that the presence of outliers in data usually introduces additional errors and biases, which typically leads to a degradation in the precision of volatility forecasts. However, correcting outliers can mitigate these adverse effects. This study corrects the additive outliers through a weighting method and let these corrected values to replace the original outliers. Then, the model parameters are re-estimated based on this new return series. This approach reduces the extent to which outliers distort volatility estimates, allowing the model to better adapt to market conditions and improving the accuracy of volatility forecasts. This study introduces this approach for the first time to generalized autoregressive conditional heteroskedasticity mixed data sampling (GARCH-MIDAS) models, so as to establish an additional outliers corrected GARCH-MIDAS model (AO-GARCH-MIDAS). This pioneering approach marks a unique innovation. The research employs a diverse array of evaluation methods to validate the model’s robustness and consistently demonstrates its dependable performance. Findings unequivocally reveal the substantial influence of outliers on the model’s predictive capacity, with the AO-GARCH-MIDAS model exhibiting consistent superiority across all evaluation criteria. Additionally, while the GARCH model showcases stronger estimation capabilities compared to the GARCH-MIDAS model, the latter demonstrates heightened predictive prowess. Notably, regarding variable selection, the results underscore the greater predictive informational value inherent in realized volatility over other low-frequency factors.

Authors: Yılmaz Gülşah , Coşkunçelebi Kamil , Güzel Murat Erdem , Makbul Serdar
Published: June 2024

The genus Vaccinium L. (Ericaceae) consists of shrubs or dwarf shrubs species widely distributed in Southeast Asia, America, and Europe. In the present paper, members of the genus (V. arctostaphylos, V. myrtillus, V. uliginosum, V. vitis-idaea) naturally grown in Northeast Anatolia were compared in terms of leaf venation, seed micromorphology, and palynological properties based on 16 populations in detail. Present findings revealed that number of areoles (the small area bounded by secondary veinlet) is 8–9 for V. arctostaphylos, 5–7 for V. myrtillus, 3–4 for V. uliginosum and V. vitis-idaea. Scanning electron microscope observation shows that the leaf adaxial surface is fiber-fluted in V. arctostaphylos, ruminate in V. myrtillus, V. uliginosum, and V. vitis-idaea due to epicuticular waxes. In addition, the seed shape of V. arctostaphylos in outline varies from triangular, tetragonal to oval, whereas they are lunate to reniform or falcate in the rest of the examined taxa. Epidermal cells of the seed are quadrilateral with straight anticlinal walls in V. arctostaphylos, however, they are most elongate rectangle with weakly undulate anticlinal walls in the rest species. The mean tetrad diameter (D) of pollen belonging to all examined species is 29.89 (21.47–43.22) μm while the lowest mean D was found in V. uliginosum (24.59 μm) and the highest mean D was found in V. arctostaphylos (36.74 μm). Principal component analysis based on 47 traits (flower: 9, leaf: 18, seed and fruit: 9 and pollen: 11) showed that the leaf length and width, teeth numbers, tetrad diameter, equatorial axis, and polar axis were the most valuable characters to distinguish the examined taxa in the present paper.

Authors: Maia Lília , Da Cruz Daniele , Abreu Letícia , Caceres Miguel , Da Silva César , Hung Celeste , Feres Magda , Retamal-Valdes Belén
Published: June 2024

ChatGPT Introduction: Necrotizing periodontal diseases (NPD) are acute lesions with a rapid onset that may cause considerable periodontal tissue destruction. Among these conditions, necrotizing gingivitis (NG) is caused by microorganisms from the oral biofilm and is associated with predisposing factors such as psychological stress, HIV/AIDS, alcohol and tobacco consumption, malnutrition, inadequate oral hygiene, and other systemic conditions that may compromise the host immune response. Objective: The aim of this narrative literature review was to describe the available evidence on the diagnosis and treatment of NG and present a successfully treated case of NG in a 22-year-old woman. Case report: The patient was a smoker, had poor oral hygiene, and was experiencing psychological stress. Her complaints were abundant gingival bleeding and halitosis during the past two weeks preceding the first appointment. Clinical findings included considerable biofilm accumulation, generalized gingival bleeding, pseudomembrane, and necrotic tissue. Treatment consisted of supragingival scaling, professional prophylaxis, 0.12% chlorhexidine rinsing for two weeks, prescription of analgesics, and oral hygiene instructions. Results: The patient’s response to initial therapy was satisfactory. Successful clinical outcomes were observed at seven days after initial therapy, and the patient has remained stable without signs of disease recurrence for six months. Conclusion: Periodontal health and function were successfully reestablished.

Authors: Skumar Swathy , Jayakumari Nisha , Sethuraman Shruthi
Published: June 2024

Objective: The aim of the study was to evaluate the efficacy of calcium phosphosilicate bioactive glass in combination with Platelet Rich Fibrin (PRF) in the treatment of horizontal bone defects in stages II and III periodontitis. Materials and Methods: The randomized controlled trial included 51 sites of horizontal bone defects from 4 patients with stages II and III periodontitis. The three treatment groups were: Group A - open flap debridement (OFD) + bone graft + PRF gel; Group B - OFD + bone graft + PRF gel covered by PRF membrane; Group C - OFD alone. The clinical and radiographic parameters were recorded at baseline and 9 months post-surgery. Results: All three groups showed statistically significant improvement in clinical and radiographic parameters, except for defect width at 9 months post-surgery. Conclusion: The findings of the present study allow us to conclude that the use of PRF in combination with bone graft can serve as a promising therapeutic approach for the treatment of horizontal bone defects, resulting in improvement of both clinical and radiographic parameters.
Development of an application and proposal of recommendations to increase awareness of periodontal diseases for patients: concepts, rationale, and use
Authors: Duque Andrés , Silva Carlos , Rosing Cassiano
Published: June 2024

Objective: To develop an application for patients aimed at promoting disease awareness and making evidence-based recommendations to seek professional care or preventive strategies. Materials and Methods: Three expert periodontists identified parameters that, according to the evidence, could represent sociodemographic characteristics, signs, symptoms, or medical conditions that can be important to alert the patient about periodontal health. Each parameter was transformed into a self-questionnaire with a single response, which could be completed using a web application. A focus group was convened with professionals and patients who provided feedback on understanding and relevance and made suggestions for improvement. Results: Several meetings were held to analyze all the possible characteristics/parameters/situations/habits involved in periodontal diseases. The parameters taken into account were bleeding, mobility or loss of teeth due to mobility, gingival recession, visible plaque or calculus, redness or swelling, halitosis, age group to which the patient belongs, frequency of visits to the dentist, diabetes, smoking habit, use of toothpaste, and use of devices for interdental hygiene. To achieve the simplicity of the application, the experts transformed the parameters into 12 questions. Conclusion: The use of this tool in a structured manner helps achieve better patient-professional communication and provides guidance throughout the use of preventive strategies.

Stát jako organismus? Kritická reflexe dosavadních interpretací konceptu státu Friedricha Ratzela
Authors: Urban Martin
Published: June 2024

Friedrich Ratzel (1844–1904) is often portrayed in the Czech context as a controversial figure in the development of political-geographical or geopolitical thought. This is probably a consequence of the lack of attention and research interest in the Czech Republic. Nevertheless, his conception of the state resonates quite strongly in the domestic literature. Available sources indicate that under the influence of Social Darwinism he came up with the idea of the state as a (living or biological) organism that must grow (expand its Lebensraum), become stronger and occupy more and more space in order to survive (in the struggle for life). This interpretation, which is in fact very misleading, forms an important pillar of Ratzel’s overall negative perception. For it implies that his conception of the state is an application of Darwin’s natural selection and the struggle for survival to human society, states and international relations. Such an interpretation of Ratzel’s thought sounds truly sinister, and in this vein could be used to justify territorial expansion as the natural right of the stronger. On closer examination, however, it turns out that the Social Darwinist interpretation of Ratzel’s thought is highly questionable and that his conception of the state cannot be used in this way.
Exhibiting the Great Patriotic War in Soviet capitals: Moscow, Kyiv, Minsk
Authors: Free Anya
Published: June 2024

During World War II, Soviet museums constituted an important part of the war propaganda machine and were used by the Soviet state to mobilize its population and to create a public historical narrative about the war. Staff at Soviet museums began organizing war-related patriotic exhibitions from the very first days of the German invasion in June 1941. This article focuses on two types of war-themed exhibitions and museums that were prominent in the Soviet urban spaces during the war and immediately after: trophy exhibitions and exhibitions and museums that focused on constructing historical narratives about the war. Among the main topics of the latter exhibitions were partisan resistance, German atrocities, and the central role of the Communist Party and Stalin personally. While the creators of these war museums adhered to the ideological frameworks and museum content plans developed by Moscow’s professional ideologists, I demonstrate that local museum workers were able, to some extent, to deviate from centrally prescribed narratives and to engage their own agency and creativity, and that the extent of this deviation was largely defined by regional specifics and by individual efforts and local circumstances. The impact of regional differences in the narration of the war is especially evident in the comparison of the representation of the Holocaust in museums in Kyiv and Minsk. Finally, I demonstrate that local circumstances were a major factor in the fate of each museum after the end of the war.
Patient result monitoring of HbA1c shows small seasonal variations and steady decrease over more than 10 years
Authors: Rollborn Niclas , Kultima Kim , Larsson Anders
Published: June 2024

Objectives

Internal and external quality assurance materials often use highly processed matrixes. This can render the materials non-commutable. Monitoring laboratory methods with patient medians helps in identifying and correcting systematic errors that may affect diagnostic accuracy. The aim of the present study was to use HbA1c patient results for monitoring of method performance over time.

Methods

Test HbA1c results from 2010 to 2022 was analyzed (n=722,553) regarding changes over time and seasonal variation. The HbA1c testing was initially performed on a Cobas 501 instrument using immunological detection but in May 2017 the method was replaced by capillary electrophoresis on Capillarys 3 Tera.

Results

There was a steady decrease in HbA1c values. From 2011 to 2021 the decrease was for 0.10 percentile 6.6 %, lower quartile 7.9 %, median 10.2 %, mean values 9 %, upper quartile 11.2 %, and 0.90 percentile 9.3 %. No clear shift in HbA1c levels was observed due to the shift in methods. The median HbA1c values per month was approximately 44 mmol/mol (6.2 %, DCCT/NGSP). The only month with a median HbA1c that differed by more than 1 mmol/mol was July with a median value of 42 mmol/mol (6.0 %).

Conclusions

The patient data showed a similar decrease as in the National Diabetes Register which indicates that the method is stable over time without any sudden changes and that the seasonal variation is low. The continuous decrease in HbA1c values over time is most likely to a shift towards earlier detection of patient with diabetes and improved treatment.
Stress relaxation experimental research and prediction of GFRP pipes under ring deflection condition
Authors: Shen Tong , Chen Jianzhong , Lv Yong , Zhang Xiaoyu , Huang Li
Published: June 2024

Glass fiber-reinforced plastic (GFRP) pipes are widely used as buried pipes in petrochemical and other industries. At present, in-depth studies have been conducted on GFRP pipes in terms of internal hydrostatic pressure, axial compression, and cyclic internal pressure, especially limited research has been carried out on transverse load, especially stress relaxation behavior. In this study, GFRP pipes with three different component contents were subjected to different initial deflections at different temperatures and subjected to stress relaxation tests for 1000 h. The findings demonstrate that the stress relaxation behavior of GFRP pipes is not affected by the initial deflection. Rather, it is primarily influenced by temperature and sand entrapment content, which are identified as the key factors determining the stress relaxation behavior of GFRP pipes. In addition, the time-temperature superposition principle (TTSP) was used to pass the test results to obtain a smooth master curve and verify the applicability of TTSP on GFRP pipes. Subsequently, the relaxation performance of GFRP pipes was predicted after 50 years. This research result contributes to a more comprehensive understanding of the stress relaxation behavior of GFRP through accelerated testing and offers crucial insights into the application of GFRP pipes.
Study of fractional telegraph equation via Shehu homotopy perturbation method
Authors: Kapoor Mamta , Bin Turki Nasser , Shah Nehad Ali
Published: June 2024

The iterative Shehu transform homotopy perturbation method (HPM) is used in the present research to address fractional telegraph equations in different dimensions, respectively. Considered equations particularly stand out in the field of material science and certain other significant fields. A graphic comparison of estimated and actual results is used to assess the validity and efficacy of the suggested technique. Graphs show a match of approximate to exact findings. Without any linearization or discretization, the iterative Shehu HPM offers a reliable and efficient way to deliver approximations and accurate outcomes that is also error-free. The development of numerical regimes based on discretization is difficult and expensive computationally. Additionally, discretization error is produced as a result of discretization in purely numerical regimes. The present regime has produced robust results and is time-efficient. Also, no discretization error was produced.
Kein Schlaraffenland, nirgends: Rekonstruktive Analysen von Kinderzeichnungen im historischen Vergleich
Authors: Kleeberg-Niepage Andrea , Marx Marie Theres
Published: June 2024

Die bis heute selten genutzten Kinderzeichnungen waren zu Beginn des 20. Jahrhunderts Gegenstand eines intensiven Forschungsstrangs in der psychologischen und pädagogischen Kindheitsforschung. Unter anderem der Psychologe William Stern führte umfangreiche Sammlungen von Kinderzeichnungen durch, verbunden mit der Hoffnung, Einblicke in das kindliche Seelenleben zu gewinnen. In diesem Beitrag re-analysieren wir zwei historische Kinderzeichnungen aus der Schlaraffenland-Sammlung Sterns von 1905 mit der dokumentarischen Bildanalyse und vergleichen sie mit zwei Zeichnungen aus einer Replikationsstudie von 2019. Die Befunde zeigen den Gewinn der Analyse von Kinderzeichnungen und insbesondere eines rekonstruktiven Vorgehens für die Elaboration kindlicher Perspektiven jenseits sprachlicher Zugänge. Zudem wird das Potential von Kinderzeichnungen für die historische Kindheitsforschung deutlich, die bislang vorrangig mit Quellen über Kinder und weniger von Kindern arbeitet. Hier kann die Bearbeitung bisher unberücksichtigter Kinderzeichnungen mit rekonstruktiven Methoden Einblicke in kindliche Erfahrungsräume aus früheren Epochen ermöglichen.

Published: June 2024

This article analyses selected challenges of remote education, focusing on the impact of the COVID-19 pandemic. It is divided into a theoretical part, synthetically explaining the key challenges related to remote education: social interactions, students' motivation and engagement, and an empirical part, presenting the results of a survey conducted on 1828 students at the Cracow University of Economics. The empirical research enabled analysis of the impact of selected distance education factors on the level of perceived learning outcomes by students, with a particular focus on social interactions (both between teachers and students, and among students), student motivation, and engagement in remote learning environments. The data was collected through a survey distributed in 2020 and 2022, using the Computer Assisted Web Interviewing (CAWI) technique via Google Forms. The results indicate moderate improvements in social interaction and motivation over time, with a slight decrease in the perceived effectiveness of remote learning. The literature review and empirical study reveal changes in the quality, motivation, and engagement of interaction, emphasising the need to adjust teaching strategies in the areas considered to increase the effectiveness of remote education. This study enriches the current literature by addressing gaps and providing suggestions for directions of future research, additionally providing practical recommendations for teachers and educational institutions to improve the efficacy of remote learning.

Published: June 2024

Memes are not new concepts, but they have garnered popularity recently. They are a prevalent form of communication on various social media platforms. However, due to a lack of concrete literature (Al Rashdi, 2020), there is still some initial scepticism surrounding them. This paper uses a systematic literature review to create a pool of research papers to be examined to chart the conceptual development of memes, determine how they are used in different fields, and present a vision of memes in the near future. It identifies eleven areas which were studied in parallel to memes, suggesting possible meme applications and development. It adopts the PRISMA 2020 framework to ensure systematic screening and reporting of relevant papers from various databases.

This paper critically assesses Business Process Management (BPM) education in Poland and provides evidence-based recommendations for improvement. Through a survey of 44 BPM educators, the study evaluates BPM lifecycle coverage, IT tool utilization, and incorporation of the Six Core Elements of BPM. The findings reveal a focus on process modeling and analysis, identifying gaps in the way the entire BPM lifecycle is addressed. Despite the utilization of various IT tools, there is a notable absence of coverage for emerging topics such as process mining, AI, and Robotic Process Automation. Only 12% of courses cover all Six Core Elements of BPM, and there is a critical gap in student education, which is the underrepresentation of the People and Culture elements. The paper concludes with a manifesto for greater alignment between academic education and industry needs through comprehensive BPM curricula, dedicated software tools, and more robust coverage of the strategic and governance aspects of BPM. This will bridge the gap between academic education and real-world BPM applications, so that graduates can be better prepared for the challenges of the modern business landscape, which can enhance the quality and effectiveness of BPM education, thereby aligning it with the evolving demands of the business environment and contributing to the growth and competitiveness of organizations in Poland.

First-trimester pregnancy losses are commonly attributed to chromosomal abnormalities. The causes of pregnancy loss following transfer of a euploid embryo are not fully elucidated. The aim of this study was to evaluate clinical and embryological parameters for pregnancy failure following the transfer of a single euploid embryo. Pregnancy outcomes of single euploid embryo transfers from a single centre between January 2017 and March 2020 were retrospectively evaluated. Several clinical and embryological parameters were evaluated in consideration to pregnancy outcomes; total pregnancy loss and live birth (LB). Endometrial preparation type, number of previous frozen embryo transfer cycles, history of recurrent pregnancy loss, higher body mass index, presence of endometriosis and/or adenomyosis and embryo quality were found to be significantly different between two groups. Morphokinetic parameter analysis of 523 euploid embryos using time-lapse imaging did not show any statistical differences between the two groups; however, a significantly higher rate of uneven blastomeres in the cleavage stage was observed in the total pregnancy loss group. Evaluation of clinical and embryological data can reveal possible factors associated with pregnancy loss that can facilitate improved patient consultation. Feasible interventions can potentially increase the chance of achieving an LB.

Lay Abstract

Like natural pregnancies, not all pregnancies following fertility treatment go to term. The most common reason for these losses is that these embryos lack the genetic constitution compatible with live birth. Combined with fertility treatment, genetic tests can evaluate the genetic ability of embryos to go to term. Monitoring the outcome of pregnancies resulting from such embryos can help us identify whether and which conditions specific to treatment can lead to pregnancy loss. The analysis identified four parameters associated with embryo loss: Embryo quality and division patterns, existence of previous treatment and treatment type.

Dabei sind Maßnahmen wie Sicherungsinstrumente notwendig, um Risiken zu begrenzen. Auf dieser Basis werden speziell Aluminiumpreisrisiken und vor allem die Sicherung mittels Derivaten am Beispiel eines Aluminiumproduzenten dargelegt.
Inflationsbedingte Anpassung des Controllings
Authors: Lubos Günter
Published: June 2024

Aktuell zeigt sich ein Rückgang der Inflation. Auch die Lage der Lieferketten, aus der inflationäreWirkungen resultierten, hat sich entspannt. Hohe Einstandspreise als Konsequenz von Rohstoff- und Materialengpässen haben abgenommen. Doch trotz dieser Entwicklungen ist das Thema Inflation für das Controlling weiter relevant. Der Artikel zeigt auf, wo und wie sich die Inflation auf das Instrumentenportfolio des Controllings auswirkt. Er gibt Hinweise, wie die Controllingfunktion ihr Instrumentarium schärfen kann, um auch in Zeiten der Inflation ein Unternehmen effektiv steuern zu können.

Summary. Aim: to determine the viability, proliferative activity, and reactive oxygen species (ROS) production in human breast cancer (BC) cells after their co-cultivation with a human microbiota member Bifidobacterium animalis. Object and methods: the study was conducted in vitro on human BC cells of MCF7, T47D, and MDA-MB-231 lines. Cells were co-cultured with live B. animalis bacteria in direct or metabolite-mediated (contactless co-cultivation in the Insert system) interaction between eukaryotic and bacterial cells. ROS production was assessed by flow cytometry. The expression of proteins associated with the regulation of proliferation and apoptosis in BC cells was evaluated by immunocytochemical analysis. Results: The most pronounced changes in the growth characteristics of human BC cells in vitro are caused by the direct interaction of bacterial and malignant cells, compared to the bacterial metabolite-mediated action. MCF-7 cells of the luminal subtype are most sensitive to the effects of B. animalis. Co-cultivation of BC cells with B. animalis leads to a decrease of Ki-67 expression in malignant cells, an increase in ROS production, and the expression of pro-apoptotic proteins Bax and p21WAF1. Translocalization of p21WAF1 expression from the cytoplasm to the cell nucleus was detected in T47D cells after exposure to B. animalis. Conclusions: the interaction of human BC cells with B. animalis and their secreted metabolites led to inhibition of the malignant cells proliferation, induction of oxidative stress, and apoptosis program activation in BC cells.

OBJECTIVE

To compare the efficacy (as measured by time to resolution of pain) and safety of valproate infusion and lidocaine infusion in the treatment of pediatric status migrainosus.

METHODS

We conducted a single-center retrospective cohort study from March 2014 to June 2021 evaluating children and adolescents who received a lidocaine or sodium valproate infusion for the treatment of status migrainosus. During the study period, lidocaine infusion was exclusively used before March 2016, whereas sodium valproate infusion was exclusively used afterward.

RESULTS

A total of 31 patients received lidocaine and 63 received sodium valproate infusion. Patients in the lidocaine group achieved significantly faster control of pain with median hours to pain free of 11.7 (interquartile range, 3.8–32.3) hours compared with 43.4 (interquartile range 13.8–68.7) hours in the valproate group (P = .002). At discharge, 21 of 31 (67.7%) of patients receiving lidocaine were pain-free compared with 26 of 59 (44.1%) of patients receiving valproate (P = .03). There were significantly more infusion interruptions of valproate compared with lidocaine for various patient-related factors (16/63, 25.4% vs 1/31, 3.2%; P = .009). More adverse effects were observed with valproate (42/63, 67%) compared with lidocaine (1/31, 3.2%; P < .001). The significant difference in hours to pain control persisted after adjustment for sex, race, age, BMI, presence of comorbidities, and pain score at admission. All patients in both groups completed the infusions and were discharged from the hospital.

CONCLUSIONS

Intravenous lidocaine infusion is associated with superior pain control and a better safety profile compared with intravenous sodium valproate infusion in status migrainosus.

Climate projections and their effects have been evaluated in the San Francisco Estuary as part of the U.S. Geological Survey’s CASCaDE2 project. Understanding the ecological effects of climate change can help manage and maintain the ecological health and productivity of the San Francisco Estuary. In this study, we assessed downscaled air temperature data from 10 global climate models (GCMs) under two representative concentration pathway (RCP) trajectories for greenhouse gas concentrations for three regions of the San Francisco Estuary: Suisun and Grizzly Bays, Suisun marsh, and the Sacramento-San Joaquin Delta. We also used previously derived regression models to estimate future water temperatures at 16 locations in the upper San Francisco Estuary. We used a thermal regime approach to summarize water temperature projections to investigate changes to the thermal regime of the upper San Francisco Estuary and used the Delta Smelt (Hypomesus transpacificus) to demonstrate the impacts that a warming climate may have on the habitat needs of this fish species. Our results suggested there were no major differences in the extent of air temperature warming among the three regions. Annual average air temperatures were projected to increase approximately 2.0 and 4.7°C by the end of the century for the low and high RCP scenarios, respectively. We found timing, frequency, and magnitude metrics varied by period and RCP scenario, while duration and variability metrics varied by space for water temperature thermal regimes. For example, the spawning window for Delta Smelt (thermal regime duration metric) is projected to expand in the future, with spawning starting earlier for both RCP scenarios for most sites. Although our thermal regime analysis focused on the life history of Delta Smelt, similar approaches could be used to assess climate change threats to a wide array of native and invasive terrestrial and aquatic species found in San Francisco Estuary.

The loss of biodiversity and biotic homogenization are on the rise in ecosystems around the world as a result of species invasions, habitat degradation, and the effects of climate change. In the Sacramento–San Joaquin Delta, non-native species make up the majority of the fish community, and declines in native species have been well documented; however, little is known about whether these trends have resulted in biotic homogenization. In this study, we used data from a long-term beach seine survey to analyze regional beta diversity trends of nearshore fish assemblages in the Delta from 1995 to 2019. Overall, we found no evidence of regional biotic homogenization occurring over the study period. Regional beta diversity increased moderately over time and was significantly influenced by the high interannual variability of freshwater inflow. These beta diversity patterns were driven by the non-native Mississippi Silverside that has proliferated in the system in recent years, but also by a handful of native fish species such as the Sacramento Sucker, Tule Perch, and Splittail. Overall, our results offer a contrast to other highly invaded ecosystems around the world and suggest that despite the near extinction of some native fish species, there remain pockets of suitable habitat in the Delta that may play a key role in the conservation of remnant native fish diversity.
Coentro

O coentro é uma das mais antigas ervas, utilizada há aproximadamente 3.000 anos, tanto na culinária quanto para uso medicinal. Conforme descrito por Grieve (1971 apud Burdock; Carabin, 2009), o coentro foi mencionado na literatura sânscrita em 5000 a.C. e no Papiro de Ebers, compilação egípcia de textos médicos, uma das mais antigas obras médicas conhecidas, datada de 1550 a.C. (Britannica, 2023). Era usado na medicina tradicional grega por Hipócrates (cerca de 460- 377 a.C.). As sementes de coentro foram encontradas no túmulo do Faraó egípcio Ramsés. Os egípcios chamam essa erva de “tempero da felicidade” (Burdock; Carabin, 2009).
Estragão

O estragão (Artemisia dracunculus) é uma herbácea perene, de folhas pequenas e estreitas. Ela é encontrada, naturalmente, em vastas áreas do Hemisfério Norte: do leste da Europa ao centro e ao leste da Ásia até o oeste da América do Norte, e espalhada do sul ao norte da Índia e o México (Vincenzi et al., 2000; Gandra et al., 2013). A planta, originária do Oriente Médio, chegou à Europa no século XVI pela Espanha mourisca, sendo utilizada como condimento em grelhados e até em bebidas geladas (Norman, 1990). São conhecidas duas espécies de estragão: o estragão-francês, ou estragão verdadeiro, e o estragão-russo. O estragão-francês (A. dracunculus Linn, var. sativa) não produz sementes e é reproduzido por estacas, não tolerando o excesso de luminosidade nem o excesso de chuvas. Dificilmente é encontrado nas condições brasileiras. O estragão-russo (A. dracunculus, var. inodora, também conhecido como Artemisia dracunculoides) produz sementes em abundância e é mais adaptado às nossas condições. Embora quase inodoro, desenvolve algum aroma com a idade, não tendo grande valor comercial (Carvalho et al., 2006).
