Introduction. Hydrophilic antioxidants are quite attractive for use in biology, veterinary practice and medicine because of their high bioavailability and transport rates, convenience of administration and dosing, suitable for use in infusion therapy in acute conditions. Traditional use of phenolic antioxidants did not presuppose their hydrophilic properties; rather, lipophilicity was preferred. In this regard, it is not surprising that the number of known water-soluble forms of phenolic antioxidants is very limited. Aim. Quantitative determination of the water-soluble antioxidant TF-7 substance by stripping voltam¬metry. Materials and methods. An object of the study was a new pharmaceutical substance of the water-soluble antioxidant TF-7 (3-(4-hydroxy-3,5-dimethylbenzylthio) potassium propionate). For quantitative determination, stripping voltammetry was used. Results. The main parameters of the method, in particular sweep rate, time and potential of accumulation, which have the greatest influence on the quantitative characteristics of the analytical signal, were determined. The dependence of amount of the substance on concentration and the minimum detectable concentration are established. Optimal background electrolytes were selected, on which the analytical signal appears. Assessment of linearity showed the coefficient of linearity for the method developed was 0.997. Conclusion. The selected parameters (background electrolyte, working electrode and reference electrode, accumulation potential and time, start and rate of sweep, mixing time) make it possible to quantify the water-soluble antioxidant TF-7 substance.

Współczesne tempo życia i zmieniające się środowisko w jakim żyjemy, stają się bardzo często przyczyną powstawania niekorzystnych zmian w procesie treningowym. Dodatkowo nieprawidłowo wykonujemy czynności dnia codziennego, niewłaściwie wykorzystując możliwości swojego ciała. Pewne jego części pracują za mało, a inne zbyt dużo. Odzwierciedla się to po pewnym czasie w zaburzeniach ze strony układu ruchu. Ludzkie ciało, aby mogło być w pełni sprawne, silne i zdrowe, potrzebuje by dostarczyć jemu odpowiedniej dozy aktywności fizycznej. Zatem wszelkie działanie jest związane z ruchem, któremu towarzyszą nasze zmysły: słuch, węch, wzrok, dotyk, smak. Aktywność jest to konkretna działalność, zdolność albo skłonność do działania. Predyspozycje do działania posiada każdy człowiek już od urodzenia. Być aktywnym to tyle samo, co być czynnym, robić coś, działać i wykonywać. Dzięki działaniu wzrasta ich wrażliwość a wraz z rozwojem stają się one dokładniejsze i bardziej precyzyjne. Stad też istotne dla ruchu jest stwarzanie sytuacji dydaktycznych otwartych na doświadczenia zmysłowe. Elementem czynności motorycznych jest poczucie własnego ciała. To wszystko jest aspektem socjologicznym. Każdy człowiek rozporządza pewną wiedzą o tym jak jest skonstruowany świat społeczny go otaczający. Na świat społeczny patrzymy z perspektywy małego wycinka rzeczywistości, z jakim mamy bezpośrednio do czynienia, wiedza potoczna tworzy się poprzez wymianę doświadczeń. W współczesnej kulturze fizycznej i sporcie jest też bardzo ważna płeć. Tematem płci w szkoleniu psychologiczno-pedagogicznym sportowców jest różnorodność biologiczna i społeczna między płciami oraz jej wpływ na proces szkolenia sportowego. Istnieją różnice między płciami w zakresie preferencji, motywacji, emocji, stylu komunikacji czy sposobu radzenia sobie ze stresem. To jest ważne zagadnienie dla trenerów i psychologów sportowych, którzy powinni dostosować metody pracy do indywidualnych potrzeb i cech sportowców z uwzględnieniem różnic płciowych. Jednym z najważniejszych zadań pedagogiki sportu,  procesu szkolenia jest wychowywanie sportowców oraz przygotowywanie ich pod względem fizycznym, psychicznym i społecznym. Pozytywny trener szanuje i kocha swój sport i uczy tego samego swoich podopiecznych. Problematyka płci w kulturze fizycznej i sporcie odnosi się do różnic i stereotypów dotyczących płci oraz ich wpływu na aktywność fizyczną, sport i zajęcia związane z kulturą fizyczną. Istnieją pewne wyobrażenia dotyczące płci, które mogą wpływać na to, jak dziewczyny i chłopcy są zachęcani do podejmowania aktywności fizycznej, jak są oceniani w sporcie, czy jakie dyscypliny są im rozdzielane. Ważne jest zastanowienie się nad sposobami w jaki płciowe różnice są przedstawiane w tej dziedzinie i jak można zmniejszyć ewentualne nierówności czy ograniczenia.
On M-projective curvature tensor of Lorentzian β-Kenmotsu manifold
Authors: Mishra A.K. , Prajapati P. , Rajin Rajan , Singh G.P.
Published: September 2024

In this paper, we explore the characteristics of Lorentzian β - Kenmotsu manifolds admitting M - projective curvature tensor. We demonstrate that M - projectively flat and irrotational M - projective curvature tensor of Lorentzian β - Kenmotsu manifolds are locally isometric to hyperbolic space Hn(c), where c = −β2. Further, we deal with the M - projectively flat Lorentzian β - Kenmotsu manifold that satisfies the condition R(X, Y )・S = 0. The Lorentzian β - Kenmostu manifold with conservative M - projective curvature tensor is the subject of our next analysis. Finally, we obtain certain geometrical facts if the Lorentzian β - Kenmotsu manifold satisfies the relation M(X, Y )・R = 0.

Identification of the lupine aphid Macrosiphum albifrons (Hemiptera, Aphididae) using molecular markers
Authors: Abdullaev* R. A. , Alpatieva N. V. , Vishnyakova M. A. , Radchenko E. E.
Published: September 2024

Narrow-leaved lupine is a valuable high-protein fodder crop, also promising for food use. The species composition of harmful organisms feeding on lupine has not been sufficiently studied. In 2019–2021 in the north-west of the Russian Federation (St. Petersburg, Pushkin), the species composition of insects inhabiting accessions of lupine of various origins was studied. The lupine aphid Macrosiphum albifrons, an invasive phytophagous pest of North American origin, was discovered for the first time in Russia. Using sequencing of a fragment of the mitochondrial gene for cytochrome c-oxidase subunit 1 (CO1), traditionally used for diagnosing Aphididae, the correctness of determining the species identity of the insect was verified. Specific primers have been proposed that allow amplification of a 408 bp portion of the barcode DNA to identify the pest.
Influence of adult density and plant type on the fertility of females of the predatory bug Macrolophus pygmaeus (Heteroptera, Miridae) during mass culture
Authors: Perova T. D. , Kozlova* E. G.
Published: September 2024

Macrolophus pygmaeus (Heteroptera: Miridae) is a predatory bug widely used in plant protection for pest control. During mass breeding, an important role in obtaining entomophagous products at the lowest cost is played by the selection of the optimal density of oviparous adults on the plant for oviposition and the type of host plant. In this study, we assessed the influence of the density of adult bugs and two species of tobacco, the ornamental tobacco Nicotiana alata and the cultivated tobacco N. tabacum, on female fertility. It has been established that the fertility of females is influenced by both the total leaf surface area and the size of optimal sites (main vein length) for oviposition. The volume of production is determined both by the fertility of females at different densities of their content on the plant, and by the number of females per unit area of leaf surface. The results of assessment of productivity of two tobacco species demonstrate that the higher productivity in the cultivated tobacco is achieved at the density of 20 to 30 pairs per plant, while in the ornamental tobacco – 35 to 60. To obtain the maximal productivity, the more suitable plant was the ornamental tobacco N. alata with the adult density of 40 pairs per plant.

Introduction: Increase in health IT adoption is often driven by financial support through the state. In 2020, the German Hospital Future Law passed Parliament with a schedule to see potential effects in 2023. The research question of the present study thus was if there were differences between 2017 and 2023 in selected application areas eligible for funding by the law. Methods: Availability and percentage of use in clinical units was measured in a panel of 172 hospitals for these areas. A linear mixed model with repeated measures yielded a significant increase in “medication management” and “discharge management”. Results and Discussion: In “medication management”, hospitals in a group as compared to single hospitals tripled the percentage of clinical units using IT systems for this purpose. Not-for-profit hospitals doubled their IT systems for “discharge management” when compared to for-profit hospitals. Conclusion: Whether these changes can be attributed to the Hospital Future Law is debatable due to severe delays in various fields, particularly in making funding available. There is room for speeding up particularly the administrative funding process and finally demonstrating results that are proportional to the government money invested.

Individual health data is crucial for scientific advancements, particularly in developing Artificial Intelligence (AI); however, sharing real patient information is often restricted due to privacy concerns. A promising solution to this challenge is synthetic data generation. This technique creates entirely new datasets that mimic the statistical properties of real data, while preserving confidential patient information. In this paper, we present the workflow and different services developed in the context of Germany’s National Data Infrastructure project NFDI4Health. First, two state-of-the-art AI tools (namely, VAMBN and MultiNODEs) for generating synthetic health data are outlined. Further, we introduce SYNDAT (a public web-based tool) which allows users to visualize and assess the quality and risk of synthetic data provided by desired generative models. Additionally, the utility of the proposed methods and the web-based tool is showcased using data from Alzheimer’s Disease Neuroimaging Initiative (ADNI) and the Center for Cancer Registry Data of the Robert Koch Institute (RKI).

Introduction: The Local Data Hub (LDH) is a platform for FAIR sharing of medical research (meta-)data. In order to promote the usage of LDH in different research communities, it is important to understand the domain-specific needs, solutions currently used for data organization and provide support for seamless uploads to a LDH. In this work, we analyze the use case of microneurography, which is an electrophysiological technique for analyzing neural activity. Methods: After performing a requirements analysis in dialogue with microneurography researchers, we propose a concept-mapping and a workflow, for the researchers to transform and upload their metadata. Further, we implemented a semi-automatic upload extension to odMLtables, a template-based tool for handling metadata in the electrophysiological community. Results: The open-source implementation enables the odML-to-LDH concept mapping, allows data anonymization from within the tool and the creation of custom-made summaries on the underlying data sets. Discussion: This concludes a first step towards integrating improved FAIR processes into the research laboratory’s daily workflow. In future work, we will extend this approach to other use cases to disseminate the usage of LDHs in a larger research community.
Early Multimodal Data Integration for Data-Driven Medical Research – A Scoping Review
Authors: Gehrmann Julia , Beyan Oya
Published: September 2024

Introduction: Data-driven medical research (DDMR) needs multimodal data (MMD) to sufficiently capture the complexity of clinical cases. Methods for early multimodal data integration (MMDI), i.e. integration of the data before performing a data analysis, vary from basic concatenation to applying Deep Learning, each with distinct characteristics and challenges. Besides early MMDI, there exists late MMDI which performs modality-specific data analyses and then combines the analysis results. Methods: We conducted a scoping review, following PRISMA guidelines, to find and analyze 21 reviews on methods for early MMDI between 2019 and 2024. Results: Our analysis categorized these methods into four groups and summarized group-specific characteristics that are relevant for choosing the optimal method combination for MMDI pipelines in DDMR projects. Moreover, we found that early MMDI is often performed by executing several methods subsequently in a pipeline. This early MMDI pipeline is usually subject to manual optimization. Discussion: Our focus was on structural integration in DDMR. The choice of MMDI method depends on the research setting, complexity, and the researcher team’s expertise. Future research could focus on comparing early and late MMDI approaches as well as automating the optimization of MMDI pipelines to integrate vast amounts of real-world medical data effectively, facilitating holistic DDMR.

Introduction: Medical research studies which involve electronic data capture of sensitive data about human subjects need to manage medical and identifying participant data in a secure manner. To protect the identity of data subjects, an independent trusted third party should be responsible for pseudonymization and management of the identifying data. Methods: We have developed a web-based integrated solution that combines REDCap as an electronic data capture system with the trusted third party software tools of the University Medicine Greifswald, which provides study personnel with a single user interface for both clinical data entry and management of identities, pseudonyms and informed consents. Results: Integration of the two platforms enables a seamless workflow of registering new participants, entering identifying and consent information, and generating pseudonyms in the trusted third party system, with subsequent capturing of medical data in the electronic data capture system, while maintaining strict separation of medical and identifying data in the two independently managed systems. Conclusion: Our solution enables a time-efficient data entry workflow, provides a high level of data protection by minimizing visibility of identifying information and pseudonym lists, and avoids errors introduced by manual transfer of pseudonyms between separate systems.

Introduction: Trial recruitment is a crucial factor for precision oncology, potentially improving patient outcomes and generating new scientific evidence. To identify suitable, biomarker-based trials for patients’ clinicians need to screen multiple clinical trial registries which lack support for modern trial designs and offer only limited options to filter for in- and exclusion criteria. Several registries provide trial information but are limited regarding factors like timeliness, quality of information and capability for semantic, terminology enhanced searching for aspects like specific inclusion criteria. Methods: We specified a Fast Healthcare Interoperable Resources (FHIR) Implementation Guide (IG) to represent clinical trials and their meta data. We embedded it into a community driven approach to maintain clinical trial data, which is fed by openly available data sources and later annotated by platform users. A governance model was developed to manage community contributions and responsibilities. Results: We implemented Community Annotated Trial Search (CATS), an interactive platform for clinical trials for the scientific community with an open and interoperable information model. It provides a base to collaboratively annotate clinical trials and serves as a comprehensive information source for community members. Its terminology driven annotations are coined towards precision oncology, but its principles can be transferred to other contexts. Conclusion: It is possible to use the FHIR standard and an open-source information model represented in our IG to build an open, interoperable clinical trial register. Advanced features like user suggestions and audit trails of individual resource fields could be represented by extending the FHIR standard. CATS is the first implementation of an open-for-collaboration clinical trial registry with modern oncological trial designs and machine-to-machine communication in mind and its methodology could be extended to other medical fields besides precision oncology. Due to its well-defined interfaces, it has the potential to provide automated patient recruitment decision support for precision oncology trials in digital applications.
