Nerve injury of the central nervous system and the peripheral nervous system still poses a major challenge in modern clinics. Understanding the roles of neurotrophic factors and their molecular mechanisms on neuro-regeneration will not only benefit patients with neural damage but could potentially treat neurodegenerative disorders, such as amyotrophic lateral sclerosis. In this study, we showed that human IL12 p40-p40 homodimer (hIL12p80) within PLA and PLGA conduits improved sciatic nerve regeneration in mice. As such, the group of conduits with NSCs and hIL12p80 (CNI) showed the best recovery among the groups in the sciatic functional index (SFI), compound muscle action potential (CMAP), and Rotarod performance analyses. In addition, the CNI group had a faster recovery and outperformed the other groups in SFI and Rotarod performance tests beginning in the fourth week post-surgery. Immunohistochemistry showed that the CNI group increased the diameter of the newly regenerated nerve by two-fold (p < 0.01). In vitro studies showed that hIL12p80 stimulated differentiation of mouse NSCs to oligodendrocyte lineages through phosphorylation of Stat3 at Y705 and S727. Furthermore, implantation using PLGA conduits (C2.0 and C2.1) showed better recovery in the Rotarod test and CMAP than using PLA conduits in FVB mice. In B6 mice, the group with C2.1 + NSCs + hIL12p80 (C2.1NI) not only promoted sciatic functional recovery but also reduced the rate of experimental autotomy. These results suggested that hIL12p80, combined with NSCs, enhanced the functional recovery and accelerated the regeneration of damaged nerves in the sciatic nerve injury mice. Our findings could further shed light on IL12′s application not only in damaged nerves but also in rectifying the oligodendrocytes’ defects in neurodegenerative diseases, such as amyotrophic lateral sclerosis and multiple sclerosis.
Este artículo examina las temáticas de la migración, la vulnerabilidad y la violencia, tomando en consideración algunos diagnósticos en materia de seguridad y un análisis sobre el caso específico de los migrantes centroamericanos en tránsito por el noreste de México. Combina información documental obtenida de diversas fuentes y una encuesta realizada en albergues de migrantes. Los estados de Tamaulipas, Nuevo León y Coahuila son una zona de vital importancia no sólo para migrantes sino que también para traficantes de personas y de drogas. Algunos de los puntos a exponer son: el incremento de los flujos migratorios y las nuevas rutas de tránsito. El tema central es mostrar los riesgos y peligros que a diario enfrentan los migrantes a raíz del incremento de medidas de seguridad y el clima de violencia en el corredor migratorio de México-Estados Unidos. El objetivo es demostrar con evidencia empírica porqué el noreste de México se ha convertido en la ruta más peligrosa para los centroamericanos en tránsito por México.
We have developed an application-based approach to introductory courses in computer science. This approach follows an apprenticeship model of learning, where students begin by reading, studying, and extending programs written by experienced and expert programmers. Applications play a central role since programming constructs are motivated and introduced in the context of applications, not the other way around as is the tradition in most texts and courses. Under our applied approach, (1) students are able to learn from interesting real-world examples, (2) the synthesis of different programming constructs is supported using incremental examples, and (3) good design is stressed vis code and concept reuse. In this paper, we provide several examples of our method as well as pointers to all the material we have developed which is freely available electronically. The philosophy underlying this method transcends a particular programming language, but we present our examples using C++ since that is the language used in the CS 1 and CS 2 courses at Duke. This method has been used with equal success using ISETL at Dickinson.
Abstract The magnetic behaviour of Cs2MYbF6 (M = Na, K, Rb) and Cs2NaYbBr6 has been studied in the temperature range between 3.5 and 251.3 K. The magnetic data are interpreted by means of a previously developed model in which the influence of the crystal field is theoretically described by the angular overlap model. The obtained values of the angular overlap parameter eσ(R) for the individual compounds are discussed and compared with each other. The energy values of the crystal-field levels of the 2F7/2 ground state are calculated.
This article discusses important aspects of cybersecurity in mobile banking applications. The article analyses in detail potential threats and effective strategies for their prevention and counteraction. Due to the rapid development of digital technologies in the banking industry, mobile applications and online services have become a necessary component of financial interaction between customers, providing convenient and efficient financial transactions. However, the development of the functionality of such applications gives rise to new cybersecurity challenges that information security professionals are actively addressing. The article is devoted to a comprehensive review of international and Ukrainian cybersecurity standards in the banking sector, and also contains quick review of mobile applications of well-known Ukrainian banks. Based on this review basic recommendations for improving cybersecurity in such applications are formulated. The article considers the impact of customer comfort on the level of security. In addition, the article considers the impact of the level of security in the banking sector on the overall digitalisation of the financial industry. It is noted that improving the level of security can stimulate and support digitalisation processes, ensuring customer trust and optimal use of mobile banking applications. A comprehensive approach to assessing the level of security, comparing various applications and standards (both Ukrainian and international), as well as considering the relationship between security issues and innovations in banking, make this work useful for understanding the genesis of cyber security in mobile banking.
Because of technology developments, the ECG yields improved outcomes in the realm of biomedical science and research. The Electrocardiogram reveals basic the heart's electrical activity. Early detection of aberrant heart disorders is crucial for diagnosing cardiac problems and averting sudden cardiac deaths. Measurements on an electrocardiogram (ECG) among people with comparable cardiac issues are essentially equal. Analyzing the Electrocardiogram characteristics can help predict abnormalities. Medical professionals presently base the preponderance of their Electrocardiogram diagnosis on their unique particular areas of expertise, which places a substantial load on their shoulders and reduces their performance. The use of technology that automatically analyses ECGs as hospital personnel performs their duties will be advantageous. A suitable algorithm must be able to categories Input signal with uncertain awesome feature on just how much they approximate Input signal having known characteristics in order to speed up the identification of heart illnesses. A possibility of identifying a tachycardia is raised if this predictor can reliably recognize connections, and this technique may be helpful in lab settings. To accurately diagnose myocardial illness, a powerful machine learning technique should be used. Through using recommended method, the effectiveness of cardiovascular disease identification using ECG dataset was evaluated. The reliability, sensitivities, and validity obtained using the Svm algorithm were 99.314%, 97.60%, and 97.60% respectively.
The complexity of the developed web applications is growing every year, which, in turn, makes it difficult to ensure their security. That is why it is advisable to pay special attention to the critical problems of software protection. The ability to assess risks and prevent vulnerabilities at the product design stage is an extremely important task, which reduces the potential difficulties in the operation of the application. In recent years, the number of data breaches in all market sectors has decreased, but their consequences have become more dangerous. Among all attacks, attacks on web applications account for more than 50 percent. According to the OWASP Top Ten list of the vulnerabilities, the relevant categories of vulnerabilities and directions of attacks on existing web applications were worked out in the work. Effective ways of their prevention are considered. Recommendations for implementing and maintaining the security of applications developed using the ReactJS library are provided. The most common security threats to React-based products throughout the application life cycle have been identified. Modern way of ReactJS optimization are considered.

Maintaining the employability of employees: gradual reintegration in a large German chemical company Objectives: Gradual reintegration is a measure in the return-to-work process and is part of the occupational health management at BASF SE, which is the responsibility of Corporate Health Management. This article aims to describe the gradual reintegration of employees of BASF SE in Ludwigshafen in the years 2016 to 2021. Methods: Data on the start and end of the gradual reintegration, the results of reintegration and the duration of previous incapacity for work, including relevant diagnoses, was entered into the electronic patient file (AMEDIS) by the responsible occupational physicians and supplemented by information on age, gender, working time system and occupational group as well as occupational health screening data on smoking status, weight and height. Results: From 2016 to 2021, 3260 gradual reintegrations were carried out on 2826 people at BASF SE’s main site in Ludwigshafen. The participants were on average 49 years old and 18 % were female. More than 90 % of the reintegrations were successfully completed (with or without health restrictions). Ill-health retirement was required for less than 1 % (n = 11). Participants were unable to work for 137 days (median; IQR: 92–218) prior to the start of reintegration. The most common diagnosis groups were mental and behavioural disorders and diseases of the musculoskeletal system, followed by cardiovascular diseases, injuries and cases of poisoning. A successful gradual reintegration took a median of 27 days (IQR: 23–40) to complete. Conclusions: Gradual reintegration is well established as a successful tool for maintaining employability after prolonged incapacity for work. Occupational physicians bring their knowledge of the jobs and the organisational structure within the company and are thus able to shape the gradual reintegration individually and according to requirements. Keywords: gradual reintegration – corporate integration management – incapacity for work – preservation of employability
