Published: January 2024

As a clean and efficient energy conversion device, solid oxide fuel cells have been garnering attention due to their environmentally friendly and fuel adaptability. Consequently, they have become one of the current research directions of new energy. The cathode, as the electrochemical reaction site of an oxidation atmosphere in solid oxide fuel cells, plays a key role in determining the output performance. In recent years, the development of double perovskite cathode materials with mixed ionic and electronic conductors has made significant progress in intermediate-temperature (600-800 °C) fuel cells. These materials have the potential to deliver higher power densities and improved stability, making them promising candidates for future fuel cell applications. The Fe-based double perovskite structure cathode material has gained extensive attention due to its adjustable crystal structure and performance, as it has A(A’) or B(B’) positions in its AA’BB’O6 structure. This material has several advantages, such as high oxygen catalytic activity, low thermal expansion coefficient, and compatibility with the thermal expansion of the electrolyte. An increasing number of researchers have been exploring the performance reaction mechanism of double perovskite by modifying and adjusting its material microstructure, crystal structure, and electronic structure. In this paper, the research progress of LnBaFe2O5 and Sr2Fe2-xMoxO6 double perovskite cathode materials is reviewed to highlight the effects of various modification methods developed on electrochemical performance of these materials. Furthermore, the potential future research directions of double perovskite cathode materials are prospected.

Lithium (Li)-ion batteries have become one of the main energy sources for electric vehicles and energy storage systems, which puts forward higher requirements for the detection of battery state of health (SOH). The SOH of batteries is crucial for areas such as battery management and renewable energy storage. Accurately evaluating the SOH of batteries can optimize charging and discharging strategies and extend battery life. Therefore, accurately and effectively monitoring the SOH of Li batteries is of great significance. An ultrasonic testing technology has been proposed that can non-destructively test the Li battery SOH, enabling accurate judgment of batteries in poor or damaged conditions. Firstly, the hetero-structured MnO2-Au has been constructed as the anode for Li-ion batteries. MnO2-Au heterojunction enhances electronic conductivity and ion conductivity. The MnO2-Au has exhibited high specific capacity and superior rate performances, which can well satisfy the ultrasonic inspection of the battery. Then, the ultrasonic testing has been conducted on batteries with different ages. The results suggest that batteries with short circuits have the highest nonlinear coefficient, while batteries with short circuits after long cycles have the lowest nonlinear coefficient. The nonlinear coefficient of batteries with different charging and discharging states is in the middle.

Published: January 2024

As a natural material, leather has been widely used in daily life due to its high biocompatibility, wearing comfort, and excellent mechanical strength. However, with the increasing demand for a better life among people, the single function of leather has difficulty in meeting the requirements, which limits its application prospects. It is particularly important to develop multifunctional leather composites with diverse characteristics. Therefore, leather can be modified and functionally designed through physical and chemical methods towards intelligent wearable devices. From this perspective, we review the research progress of intelligent leather-based wearable composites, mainly focusing on the preparation methods and application directions in recent years. Finally, we emphasize the challenges that leather composites will face in practical applications and propose future research directions.

Published: January 2024

Novel segmented tick-borne RNA viruses belonging to the group of Jingmenviruses (JMVs) are widespread across Africa, Asia, Europe, and America. In this work, we obtained whole-genome sequences of two Kindia tick virus (KITV) isolates and performed modeling and functional annotation of the secondary structure of 5’ and 3’ UTRs from JMV and KITV viruses. UTRs of various KITV segments are characterized by: (1) polyadenylated 3’ UTRs; (2) 5’ DAR and 3’ DAR motifs; (3) a highly conserved 5’-CACAG-3’ pentanucleotide; (4) a La protein binding site; (5) multiple UAG sites providing interactions with the MSI1 protein; (6) three homologous sequences in the 5’ UTR and 3’ UTR of segment 2; (7) the segment 2 3’ UTR of a KITV/2017/1 isolate comprises two consecutive 40 nucleotide repeats forming a Y-3 structure; (8) a 35-nucleotide deletion in the second repeat of the segment 2 3’ UTR of KITV/2018/1 and KITV/2018/2 isolates, leading to a modification of the Y-3 structure; (9) two pseudoknots in the segment 2 3’ UTR; (10) the 5’ UTR and 3’ UTR are represented by patterns of conserved motifs; (11) the 5’-CAAGUG-3’ sequence occurs in early UTR hairpins. Thus, we identified regulatory elements in the UTRs of KITV, which are characteristic of orthoflaviviruses. This suggests their functional significance for the replication of JMVs and the evolutionary similarity between orthoflaviviruses and segmented flavi-like viruses.

Significance Preeclampsia is one of the common complications that significantly affects both pregnancy progress and delivery and the newborn health and can be also frequently followed by the death of mother and baby. This substantiates the need to identify risk factors for predicting preeclampsia The purpose of the study was to identify prognostic risk factors of preeclampsia. Material and methods. This systematic review analyzed modern studies on risk factors of preeclampsia and clinical, laboratory and instrumental methods of analysis to identify risk factors of preeclampsia as well as approaches to their assessment. The systematic review was conducted according to the PRISMA guidelines using certain PICO(S) criteria. Results The risk of preeclampsia should be assessed by risk factors to predict preeclampsia early in gestation. To identify such factors in various studies of Russian and foreign authors, the authors analyzed anamnestic factors and results of laboratory and instrumental diagnostic methods. Thus, a history of elevated blood pressure indicates an increased risk of preeclampsia. The highest risk of preeclampsia is registered in pregnant women with antiphospholipid syndrome. Most risk factors of preeclampsia are not potentially avoidable, except for excessive weight gain during pregnancy and multiple pregnancies, such as IVF. According to some researchers, the determination of laboratory parameters (platelet count, creatinine level, liver enzymes and urine protein) can help to predict preeclampsia. Changes in the absolute levels of angiogenic proteins of ischemic trophoblast VEGF, PlGF, sFlt-1, and sEng in mother’s blood and urine not only precede the onset of preeclampsia by several weeks or months, but also correlate with the disease severity and normalize after the delivery, suggesting a high prognostic value of this risk factor. Meta-analyses show that Doppler assessment of blood flow in uterine arteries can predict the risk of preeclampsia. Conclusion. As prognostic risk factors for preventive measures, with a high degree of probability the following set of data should be evaluated: arterial hypertension, antiphospholipid syndrome, obesity, multiple pregnancy, the history of assisted reproductive technologies, assessment results of blood flow in the uterine arteries, some laboratory blood parameters. The search for new predictive risk factors of preeclampsia requires further research.

Authors:   National Research Mordovia State University, Tomilin Oleg , Romaikin Ivan ,   National Research Mordovia State University
Published: January 2024

The constitutional right to health protection and medical care is one of the fundamental human rights. It has a rather complex implementation mechanism and assumes the functioning of a developed health organization system. The realization of the right to health protection and medical care has become particularly relevant during the spread of the new coronavirus infection COVID-19. The purpose of the study is to analyze some aspects of the constitutional right to health protection and medical care in the light of the legal positions of the highest judicial instances of the Russian Federation – the Constitutional Court of the Russian Federation and the Supreme Court of the Russian Federation. Material and methods. Legal assessments of various aspects of the right to health protection and medical care, which were given by the highest courts of Russia in connection with citizens' appeals for the protection of their rights, were investigated. The methodological basis consisted of logical and dialectical methods as well as the method of content analysis of normative and legal acts and court judgements, and a system-structural approach. Results. Defining health as a constitutional value, the supreme courts of the Russian Federation reveal a system of legal guarantees for the implementation of this constitutional right, all elements of which are interconnected. An important role in the mechanism of realization of the right to health protection and medical care, according to the highest courts of Russia, is played by constitutional principles, among which are the principles of justice, proportionality, federalism, freedom of economic activity, etc. In addition, in the materials of the practice of the higher courts concerning the provision of free medical care, attention is drawn to the need to maintain a balance between the freedom of action of medical workers and the organizational capabilities of specialized public authorities. Conclusion. In the acts of the supreme courts of Russia, the right to health protection and medical care appears as a complex competence, which is based on the category of health as an inalienable and inalienable good. This competence is based on the constitutional obligation of the Russian Federation to preserve and strengthen the health of its citizens, which presupposes a developed system of legal guarantees for its implementation
MORTALITY FROM COVID-19 AS AN INDICATOR OF REGIONAL DIFFERENCES IN LIFE QUALITY

Significance. The multifaceted nature of the novel coronavirus pandemic makes it difficult to determine the factors leading to an extremely wide variation in regional COVID-19 mortality rates. The purpose of the study is: to determine whether life quality affects mortality from COVID-19. Quality of life may be one of the factors. Material and methods. The average values of mortality from COVID-19 and its growth rate from 2020 to 2021 were compared in groups of regions with the highest and lowest indicators: conditions and quality of life, financial status, population per hospital bed and per doctor, standardized mortality from homicides, suicide and self-harm, alcohol and drug-related causes. A correlation analysis was implemented. Results. In the first year of the pandemic, significant differences in average mortality from COVID-19 were detected between groups of regions that differ in mortality from causes associated with alcohol consumption, while in the second year of the pandemic significant differences were detected between groups of regions that differ in terms of conditions and quality of life, and mortality from suicide and self-harm. Differences in mortality growth rates were registered between the same groups of regions, as well as between groups by financial status of the population and population per bed ratio. For 2020, but not for 2021, there are weak, although significantly non-zero correlations between standardized COVID-19 mortality and population per hospital bed ratio (direct), population per doctor ratio (reverse), and alcohol-related mortality (reverse). Conclusion. Life quality of the population is a factor of regional differentiation of mortality from COVID-19. In the “objective” model of life quality, mortality from COVID-19 is higher in prosperous regions, while in the “subjective” model it is lower. The growth rate of mortality in the second year of the pandemic was higher in the regions with a high standard of living. The population per bed ratio had an effect on mortality from COVID-19 only in the first year of the pandemic. Scope of application. The results obtained can be used for both planning anti-epidemic measures and developing measures to equalize the living conditions in different regions.

Significance. Physical activity is one of the key aspects of a healthy lifestyle. Regular physical activity contributes to health maintenance and promotion. The benefits of physical activity for the population are great. Numerous studies have noted a global threat in the form of a pandemic of inactivity in population. The purpose of the study is to analyze the levels of physical activity in population of cities of different size groups. Material and methods. The study used a survey on major demographic indicators and the questionnaire "Health-Promoting Lifestyle Profile – HPLP". The study covered residents of three cities by size group: Moscow as the largest city Moscow, Podolsk urban district as a large city, and Stupino urban district as a medium-size city. Results. According to the study results, the average level of physical activity in urban population is moderate in all three cities under study. The average values of physical activity levels in residents of Stupino urban district (18.14±1.15) are higher than in residents of Moscow (15.99±1.05) and Podolsk urban district (14.83±0.97), the data are reliable at p<0.05. Conclusion. The authors of the study believe that the main factors influencing the level of physical activity in urban population are as follows: promotion of a healthy lifestyle, motivation of the population to engage in physical culture, accessibility of sports facilities. Scope of application. The results of the study allow municipal administrations, regardless of the size of the municipality, to make management decisions aimed at increasing the level of physical activity in urban population.

Una “historia de mano” y una sustitución: hacia la edición crítica de la "Tragedia famosa de doña Inés de Castro, reina de Portugal" del licenciado Mejía de la Cerda
Authors: Zaghen Luca
Published: January 2024

El artículo se cifra tanto en la producción literaria de Luis y Reyes Mejía de la Cerda como en la transmisión textual de la Tragedia de doña Inés de Castro, obra indisolublemente relacionada con la Tercera parte de las comedias de Lope de Vega y cuya paternidad continúa siendo objeto de debate. Se ofrece una nueva transcripción de los testimonios del Fénix y de Luis Mejía de la Cerda en el proceso de beatificación de Juan de Dios, a fin de aclarar si el manuscrito sobre la vida del santo citada por Lope fue escrito por Luis o por Reyes. Además, se declara la procedencia del pliego empleado en un caso de sustitución que afecta a uno de los ejemplares de la princeps de la Tercera parte y la transmisión del texto de la Tragedia: el objetivo último es dar los primeros pasos hacia la edición crítica de esta pieza del licenciado Mejía de la Cerda.

Ganglion impar is a solitary ganglion located retroperitoneally at the end of para vertebral sympathetic chain and usually in front of sacrococcygeal joint. Solitary or metastatic tumour in the surrounding tissues causes poorly localized pain. This is a case of 76 year old male, who was diagnosed to have advanced metastatic adenocarcinoma prostate, presented with pain over the lower back radiating to ano rectal region since last 4 months. He had severe pain during defecation which could not be controlled with conventional high-dose opioid application but with transcoccygeal Ganglionimpar chemical neurolysis. We reasoned that blocking the ganglion impar could attenuate this sympathetically maintained pain, which would lead to a reduction in the consumption of opioids, lessen constipation, and lead to an improvement in the patient’s quality of life.

Accidental dural puncture is the most common major complication during epidural anaesthesia and causes high risk of post dural puncture headache (PDPH). Intrathecal catherisation in such cases helps in preventing leakage of CSF and thereby decreasing the incidence of PDPH. Here is one such case report of inadvertent intradural puncture during epidural anaesthesia.

Spinal anaesthesia is one of the most commonly used technique for lower abdominal and lower limbs surgeries. However its short duration of action and early arising post-operative pain moves the focus towards the use of adjuvant to it. So numbers of adjuvant from different groups were used and evaluated. Out of which opioids are the most commonly used family as an intrathecal adjuvant to local anaesthetics. Our aim of the study to evaluate the analgesic efficacy of hyperbaric Bupivacaine & Nalbuphine versus hypebaric Bupivacaine & Fentanyl in infraumbilical surgeries. The study was conducted during period of 2020 to 2022 at tertiary care center. Total 100 patients were participated in study each group includes 50. Demographic data, onset of sensory & motor block, duration of sensory and motor block, two segment regression time and first rescue analgesia time were noted. The onset of sensory and motor block was earlier in Bupivacaine plus Nalbuphine (BN) combination as compared to Fentanyl plus Bupivacaine (BF) combination. Two segment regression time was longer with BN group. Nalbuphine also shows good hemodynamic stability. Rescue analgesia time with Nalbuphine was much longer than Fentanyl. The adverse effect was also much less with Nalbuphine. Nalbuphine could be a better and settle alternative to the Fentanyl and other opioids as adjuvant to intrathecal local anaesthetics.
