Published: November 2022

The ionospheric delay is one of the important error sources in the Global Navigation Satellite System (GNSS) data processing. With the rapid construction and development of GNSS, the abundant satellite resources have brought new opportunities for ionospheric monitoring. To further investigate the performances and abilities of Galileo and BDS in ionosphere modeling, we study the ionosphere modeling based on the 15th order spherical harmonic function, and 364 stations around the world are selected for global ionospheric modeling of GPS, GLONASS, Galileo and BDS systems under ionospheric quiet and active conditions, respectively. The results show that the average biases of the ionospheric models built by GPS, GLONASS and Galileo are relatively small, which are within 2 Total Electron Content Unit (TECU) as compared to the Center for Orbit Determination in Europe (CODE) global ionospheric map (GIM), while the average biases of the models built by BDS are between 6 and 8 TECU during the ionospheric quiet and active days, respectively. In addition, in order to analyze the modeling performances before and after using BDS geostationary earth orbit (GEO) satellites, BDS is divided into two groups, in which one group contains medium earth orbit (MEO), inclined geosynchronous orbit (IGSO) and GEO satellites; and the other group contains only MEO and IGSO satellites. The results show that the influence of GEO satellites on ionospheric modeling is less than 1 TECU. Due to the distribution of the stations, the 0-value region in the ionospheric model is mainly distributed in the mid and high-latitude regions of the southern hemisphere. Since the ionospheric parameters are lumped with the Differential Code Bias (DCB), we also estimate the DCB parameters and analyze their performances. The DCB estimated in ionosphere modeling shows strong stability, with the average biases of GPS, GLONASS, Galileo and BDS under 0.25 ns, 0.25 ns, 0.2 ns and 0.42 ns, respectively. We also estimate other DCB types of the four GNSS systems. The results show that the DCB is stable and shows consistency with Chinese Academy of Sciences (CAS) DCB products.

Published: November 2022

The Advanced Himawari Imager (AHI) and Advanced Baseline Imager (ABI), respectively aboard Himawari-8 and GOES-R geostationary satellites, are two important instruments for the near-real time monitoring of active volcanoes in the Eastern Asia/Western Pacific region and the Pacific Ring of Fire. In this work, we use for the first time AHI and ABI data, at 10 min temporal resolution, to assess the behavior of a Normalized Hotspot Index (NHI) in presence of active lava flows/lakes, at Krakatau (Indonesia), Ambrym (Vanuatu) and Kilauea (HI, USA) volcanoes. Results show that the index, which is used operationally to map hot targets through the Multispectral Instrument (MSI) and the Operational Land Imager (OLI), is sensitive to high-temperature features even when short-wave infrared (SWIR) data at 2 km spatial resolution are analyzed. On the other hand, thresholds should be tailored to those data to better discriminate thermal anomalies from the background in daylight conditions. In this context, the multi-temporal analysis of NHI may enable an efficient identification of high-temperature targets without using fixed thresholds. This approach could be exported to SWIR data from the Flexible Combined Imager (FCI) instrument aboard the next Meteosat Third Generation (MTG) satellites.
Enhancing Railway Detection by Priming Neural Networks with Project Exaptations
Authors: Eickeler Felix , Borrmann André
Published: November 2022

When integrating railway constructions and refurbishments into an existing infrastructure, it is beneficial to have knowledge of the exact state, geometry, and placement of the connected assets. While new constructions and the maintenance of existing lines can directly use existing digital models and incorporate them into their processes, existing railways often predate digital technologies. This gap in digital models leaves the planning processes of new constructions and refurbishments to primarily rely on non-automated and analogue workflows. With a multitude of asset types, layouts and country-specific standards, the automatic generation of adequate detection models is complicated and needs to be tailored to the current project environment, generating considerable overhead. Addressing this issue, this paper presents the concept of priming. Priming increases the adaptation performance to highly volatile, low-data environments by leveraging previous, existing CAD projects. We introduce a translation scheme that converts the existing 3D models into realistic, project-specific, synthetic surveys and a complemental dialled-in training routine. When applied to a convolutional neural network, we show that the primed training will converge faster and with greater stability, especially when using sparse training data. Our experiments show that priming can reduce the time for network adaptation by over 50%, while also improving resilience to underrepresented object types.

Published: November 2022

Satellite passive microwave remote sensing has been extensively used to estimate snow depth (SD) and snow water equivalent (SWE) across both regional and continental scales. However, the presence of forests causes significant uncertainties in the estimations of snow parameters. Forest transmissivity is one of the most important parameters for describing the microwave radiation and scattering characteristics of forest canopies. Although many researchers have constructed models for the functional relationship between forest transmissivity and forest vegetation parameters (e.g., stand growth and accumulation), such relationships are strongly limited by the inversion accuracy of vegetation parameters, forest distribution types, and scale-transformation effects in terms of regional or global scale applications. In this research, we propose a pixel-wise forest transmissivity estimation model (Pixel-wise γ Model) based on long-term series satellite brightness temperature (TB) data for the satellite remote sensing inversion of snow parameters. The model performance is evaluated and applied in SD inversion. The results show that the SD inversion errors RMSE and Bias are 9.8 cm and −1.5 cm, respectively; the SD inversion results are improved by 41% and 84% after using the Pixel-wise γ Model, compared with the forest transmissivity model applied in the GlobSnow v3.0 product. The proposed forest transmissivity model does not depend on forest cover parameters and other ground measurement parameters, which greatly improves its application scope and simplicity.

Published: November 2022

During emergency events, we could significantly depend on the stable operation of radio communication, navigation, and radars. The ionosphere, especially its auroral regions, significantly influences radio systems, which is why scientists and engineers create systems to monitor these regions. Using data from the global GNSS network, we analyzed the 10 strongest magnetic storms of solar cycle 24: five coronal mass ejection-driven (CME-driven) and five high-speed stream-driven (HSS-driven) storms. The analysis was based on the calculation of the standard deviation of the total electron content (TEC) derivative (rate of TEC index, ROTI). Under all the storms, the ROTI featured similar dynamics: the average ROTI reaches the highest values during the main phase, and the higher the intensity is, the more intense and equatorward the average ROTI registered. The highest cross-correlations are observed with a lag of 1 h, between the IMF z-component Bz and the magnetic latitude where the highest ROTI values appear. The auroral electrojet (SME index) shows the highest impact on the ROTI dynamics. An increase in the space weather indices (in absolute value) is accompanied by a decrease in the latitude where the maximal ROTI occurs. We found that the peculiarities of a storm affect the ROTI dynamics: all the CME-driven storms feature a high cross-correlation (>0.75) between the IMF z-component Bz and the magnetic latitude where the highest ROTI appears, while the HSS-driven storms feature a lower cross-correlation (<0.75) between them. The difference in duration of similar (by maximal values of geomagnetic indices) HSS- and CME-driven storms could produce differences in the highest ROTI values. Correlations show that compared to HSS-driven storms, CME-driven ones more directly impact the ROTI values and locations of regions with a high ROTI.

Published: November 2022

Compared with anchor-based detectors, anchor-free detectors have the advantage of flexibility and a lower calculation complexity. However, in complex remote sensing scenes, the limited geometric size, weak features of objects, and widely distributed environmental elements similar to the characteristics of objects make small object detection a challenging task. To solve these issues, we propose an anchor-free detector named FE-CenterNet, which can accurately detect small objects such as vehicles in complicated remote sensing scenes. First, we designed a feature enhancement module (FEM) composed of a feature aggregation structure (FAS) and an attention generation structure (AGS). This module contributes to suppressing the interference of false alarms in the scene by mining multiscale contextual information and combining a coordinate attention mechanism, thus improving the perception of small objects. Meanwhile, to meet the high positioning accuracy requirements of small objects, we proposed a new loss function without extra calculation and time cost during the inference process. Finally, to verify the algorithm performance and provide a foundation for subsequent research, we established a dim and small vehicle dataset (DSVD) containing various objects and complex scenes. The experiment results demonstrate that the proposed method performs better than mainstream object detectors. Specifically, the average precision (AP) metric of our method is 7.2% higher than that of the original CenterNet with only a decrease of 1.3 FPS.

Published: November 2022

Global navigation satellite system (GNSS) signals are easily blocked by urban canyons, tree-lined roads, and overpasses in urban environments, making it impossible to ensure continuous and reliable positioning using only GNSS, even with the widely used precise point positioning and real-time kinematic (PPP-RTK). Since the inertial navigation system (INS) and GNSS are complementary, a tightly coupled PPP-RTK/INS model is developed to improve the positioning performance in these GNSS-challenged scenarios, in which the atmospheric corrections are used to achieve a rapid ambiguity resolution and the mechanization results from INS are utilized to assist GNSS preprocessing, re-fixing, and reconvergence. The experiment was conducted using three sets of vehicle-mounted data, and the performance of low-cost receiver and microelectromechanical system (MEMS) inertial measurement unit (IMU) was compared. The result shows that the positioning accuracy of PPP-RTK/INS can reach 2 cm in the horizontal component and 5 cm in the vertical component in the open environment. In the complex urban environment, continuous and reliable positioning can be ensured during GNSS short interruption, ambiguity can be instantaneously re-fixed with the assistance of INS, and decimeter-level positioning accuracy can be achieved. As a result, the horizontal positioning errors of more than 95% of the total epochs were within 20 cm. In addition, average positioning accuracy better than 15 cm and 30 cm in the horizontal and vertical components, respectively, can be obtained using the low-cost receiver and MEMS IMU. Compared with tactical IMU, the improvements in positioning accuracy and the ambiguity fixing rate using the geodetic receiver were more significant.

Published: November 2022

Landslides pose a greater potential risk to the Sichuan-Tibet Transportation Project, and extensive landslide inventory and mapping are essential to prevent and control geological hazards along the Sichuan-Tibet Transportation Corridor (STTC). Recently proposed landslide detection methods mainly focused on new landslides with high vegetation. In addition, there are still challenges in automatic detection of old landslides using optical images. In this paper, two methods, namely mask region-based convolutional neural networks (Mask R-CNN) and transfer learning Mask R-CNN (TL-Mask R-CNN), are presented for detecting and segmenting new and old landslides, respectively. An optical remote sensing dataset for landslide recognition along the Sichuan-Tibet Transportation Corridor (LRSTTC) is constructed as an evaluation benchmark. Our experimental results show that the recall rate and F1-score of the proposed method for new landslide detection can reach 78.47% and 79.80%, respectively. Transfer learning is adopted to detect old landslides, and our experimental results show that evaluation indices can be further improved by about 10%. Furthermore, TL-Mask R-CNN has been applied to identify ice avalanches based on the characteristics of landslides. It appears that our proposed methods can detect and segment landslides effectively along the STTC with the constructed LRSTTC dataset, which is essential for studying and preventing landslide hazards in mountainous areas.

Autoimmune diseases of the nervous system are characterized by the formation of a pronounced neurological deficit and often lead to disability. The attention of doctors and researchers is increasingly attracted to complementary medicine as an adjuvant r preventive therapy for various diseases, including autoimmune diseases. Complementary medicine is a collection of treatments that include manual therapy, osteopathy, chiropractic, kinesiology, craniosacral therapy, and other methods that are often used in conjunction with established approaches of conventional medical science. The article describes the use of complementary medicine methods for autoimmune diseases of the nervous system and demonstrates the clinical experience of using diets, osteopathic techniques, and exercise therapy. Traditional and complementary medicine is an important and often underestimated healthcare resource with many applications, especially in the prevention and treatment of autoimmune diseases of the ner vous system.
Population Dynamics of Oreochromis mossambicus and O. niloticus (Cichlidae) in Two Reservoirs in Sri Lanka
Authors: AMARASINGHE U.S. , SILVA SENA S. DE
Published: November 2022

Population dynamics of two cichlid species, Oreochromis mossambicus and 0. niloticus in two reservoirs in Sri Lanka were studied using length-based methods. Asymptotic total length (L.,.) and growth constant (K per year) of 0. mossambicus (L.,.. = 43.7 cm and K = 0.52 in Kaudulla; L_ = 45.0 cm and K = 0.45 in Minneriya) and 0. niloticus (L_ = 54.5 cm in both reservoirs; K = 0.35 and 0.48 in Kaudulla and Minneriya, respectively) were used to estimate mortality and exploitation rates (E). The growth performance of 0. mossambicus in both reservoirs was better than that of 0. mossambicus populations in various geographical areas. This may be due to introgressive hybridization between 0. mossambicus and 0. niloticus or a very favorable environment for 0. mossambicus in Sri Lank.an reservoirs which provide a variety of nutritious food sources. Length-structured Virtual Population Analysis indicates that fishing mortality rates are approximately constant throughout the recruited stocks, suggesting that the effects of gill-net selectivity on the catch samples are small. Relative yield-per-recruit analyses incorporating probabilities of capture indicate that 0. mossambicus and 0. niloticus yields in Minneriya could be increased by increasing size at first capture. In Kaudulla, any increase in E of 0. mossambicus stock would adversely affect the 0. niloticus stock. Also, increase in size at first capture of 0. niloticus to optimize yield would leave the 0. mossambicus stock underexploited.

Authors: DALZELL PAUL , AINI JOHN W.
Published: November 2022

Sustained fishing with Antillean style S-shaped and arrowhead wire mesh fish traps was undertaken on and around coral reefs in northern Papua New Guinea. Catches by weight and numbers versus soak time conformed to asymptotic curves with maxima after five days immersion. Moonphase affected catch rates, with highest catches over the period of full moon. Over 30 different families of fish were taken by the traps, but in both trap designs, catches were dominated by surgeonfish (Acanthuridae). Other dominant components of the catch were groupers (Serranidae), emperors (Lethrinidae) and parrotfish (Scaridae).
Effects of Constant Photoperiod-Temperature Regimes on the Testicular Activity of Channa punctatus
Authors: SRIVASTAVA S.J. , SINGH R.
Published: November 2022

Channa punctatus exhibits two spawning periods in a year (early April and August-September). Effects of long (16 hours) and short (8 hours) daily exposure to light at constant temperature (30"C) on the testicular activity of C. punctatus were studied over one year. The 16-hour light regime stimulated testicular maturation, advanced maturity by two months and prolonged the spawning period. The 8-hour light regime inhibited testicular maturation and caused testicular regression. The analysis of variance of testicular GSIs revealed the significant contribution of both photoperiod and temperature for testicular maturation.
A Review of Seawater Acclimation Procedures for Commercially Important Euryhaline Tilapias
Authors: PERSCHBACHER PETER W.
Published: November 2022

Procedures for acclimating commercially important euryhaline tilapias to seawater are reviewed. Single-step acclimation (intermediate salinity directly to the final salinity) has been most often used for Oreochromis mossambicus (Peters) and requires only one day at an intermediate salinity with no resulting mortality. Other tilapias which are less salt tolerant have required multistep acclimation (gradual in­crease in salinity). Time required for seawater acclimation with no mortality ranges from four days for 0. aureus (Steindachner) to eight days for O. niloticus. Research needs are discussed.

Authors: HANIFFA MOHAMAD ABDULKATHER , SELVAN SOUNDRAPANDIAN ARUL
Published: November 2022

A 30-day feed trial was conducted to examine the effects of two groups of formu­lated pelleted feeds (beef waste + rice bran + groundnut oil cake; fish waste + soybean seeds + Spirogyra maxima) on the growth and body composition of the common carp Cyprinus carpio. Fish fed on beef-based feeds showed a slight increase in the rates of feeding, absorption and metabolism. The highest feeding rate of 1,460 J-g-Lday1 and the highest conversion rate of 182 J·g-1·day1 were noticed in C. carpio fed on these feeds. The absorption efficiency was higher in fish-based feeds (77-89%) than in beef-­based feeds (65-72%), but the food conversion efficiency showed the reverse trend. Increase in protein content of the diets produced elevated values in the rates and efficiencies of food conversion in all eight experimental feeds. A positive linear relation­ship was obtained between energy density of the diets and food conversion efficiency. The highest food conversion ratio of 1. 7 was noticed in C. carpio fed on 2:1 :1 mixtures by dry weight of the above ingredients in both groups.
Production of YY Male in the Guppy Poecilia reticulata by Endocrine Sex Reversal and Progeny Testing
Authors: KAVUMPURATH SOOSAMMA , PANDIAN T.J.
Published: November 2022

Gravid Poecilia reticulata were orally administered estrogens, b-estradiol (200- 400 mgkg-1 food), diethylstilbestrol (100-1,000 mgkg-1 food), 17 a-ethynylestradiol (100- 500 mgkg-1 food) and 8-benzoate estradiol (200-800 mgkg-1 food) from days 15 to 20 after the previous parturition until the termination of gestation. Treatment with 400 mg 11,-estradiol per kg food, 300 mg diethylstilbestrol per kg food and 200 mg 1 7 a-ethynylestradiol per kg food, initiated 5-10 days prior to parturition, caused the birth of 100% females. However, S.benzoate estradiol, even if administered at high dosage levels, failed to induce 100% sex reversal. Sex-reversed females were functional and their genotype was identified by progeny testing. Sex-reversed females (XY} were mated with normal males (XY) to produce F 2 progeny. Among 21 F 2 males, each tested individually by meting with a normal female (XX), two males were identified to have YY genotype and both of them sired all-male offspring. A program for the mass production of YY broodstock is discussed.

Published: November 2022

A dermopigmentação é uma técnica que originou-se da tatuagem, sendo esta, uma arte milenar muito utilizada pelos povos orientais para pigmentação cutânea, a partir de pigmentos exógenos de diversas cores. Vem evoluindo de forma satisfatória nas últimas décadas, sendo utilizada tanto para fins estéticos, nas regiões das sobrancelhas, olhos e lábios, por exemplo, quanto para reparação de vitiligo, estrias, aréolas e cicatrizes. Em consequência do aumento da utilização dessas tintas para pigmentação cutânea, se intensificam as preocupações em relação ao potencial inflamatório desses elementos no corpo humano, surgindo a necessidade de conhecer seu comportamento e seus riscos. Assim, o objetivo do presente trabalho foi avaliar os efeitos dos pigmentos exógenos utilizados na pigmentação cutânea e sua interação na produção de mediadores lipídicos. Para isso, foram realizados ensaios para análise da dose/efeito nas concentrações de 1:100, 1:1000 e 1:10000 em macrófagos peritoneais de camundongos C57bl6, estimulados in vitro com o pigmento inorgânico. Verificou-se a viabilidade celular após 24 horas de exposição dos macrófagos ao pigmento e observamos a formação de corpúsculos lipídicos e a síntese de mediadores inflamatórios nos tempos de 2h, 4h, 6h, 8h e 24h. Os dados da avaliação de viabilidade foram submetidos à análise estatística por ANOVA e as médias comparadas por teste Tukey, valores de p<0,05 foram considerados significativos. Os dados obtidos mostraram que o pigmento inorgânico utilizado não é citotóxico para macrófagos peritoneais murinos, onde as 3 doses utilizados apresentaram viabilidade celular acima de 95%. A observação em microscopia de luz de macrófagos peritoneais murinos corados com ORO e Bodipy mostrou a formação de corpúsculos lipídicos nas 3 doses utilizadas, com maior formação na dose de 1:1000. Na análise da morfologia das células com kit panótico observamos que os macrofagos mantiveram sua forma típica e seu núcleo definido após a exposição ao pigmento. Observamos também baixa expressão de citocinas como TNF-α e IL-10. Os dados demonstraram que, o pigmento não apresenta efeito tóxico nas doses utilizadas in vitro, e apresenta um baixo efeito indutor de inflamação, visto que apesar da detecção da formação de corpúsculos lipídicos, a expressão de citocinas pró inflamátorias foi bastante reduzida.

Em busca de aulas que contribuam para o protagonismo dos estudantes, metodologias de aprendizagem vêm sendo pesquisadas como estratégias para propiciar uma aprendizagem eficiente e que contemple todos os alunos. Esta estratégia de investigação faz parte de um estudo de caso exploratório qualitativo que teve por objetivo investigar uma turma do primeiro ano do Ensino Médio, da rede particular de ensino, no formato do Ensino Remoto Emergencial, que foi apoiada a uma proposta pedagógica sustentada pela metodologia Sala de Aula Invertida (SAI), que tem como seus percussores Jonathan Bergamnn e Aaron Sams. Compreendemos que a (SAI) por si só não é suficiente para garantir qualidade na aprendizagem. Preocupados em garantir uma educação que promova a criticidade e a reflexão dos alunos em relação à matemática, embasada teoricamente nos princípios da Educação Matemática Crítica de Ole Skovsmose, elaboramos para as aulas atividades de Educação Financeira com o objetivo de estudar os conteúdos de Função Exponencial e Logarítmica dentro da vertente crítica, a fim de contribuir para a promoção de reflexão crítica e tomada de decisões conscientes em situações do cotidiano. Para Campos e Coutinho (2019), os alunos devem ser estimulados a participarem ativamente da vida em sociedade, sendo necessário gerar reflexões para que eles consigam pensar criticamente sobre situações do seu cotidiano, e a longo prazo. Sabendo que a economia influencia cada vez mais a sociedade, pois “a economia é o sistema norteador de toda a sociedade hoje, e posto que o consumo se perfaz como um dos principais organizadores da sociedade” (KISTEMAN JR. 2011, p. 44), trouxemos a Educação Financeira que, trabalhada numa perspectiva crítica, pode nos ajudar a realizar um ensino mais significativo, contribuindo para a reflexão e para as atitudes mais conscientes dos alunos. Com o levantamento inicial (projeto piloto), foi possível coletar dados e analisá-los, os quais serviram como instrumento capaz de reproduzir o estudo de caso e o desenvolvimento do Produto Educacional como resultado de nossa investigação. Dessa forma, as atividades desenvolvidas que foram validadas nessa pesquisa fazem parte do Produto Educacional, um guia didático para o professor, que foi organizado em três partes. Na primeira, trataremos do referencial teórico de nossa pesquisa, Educação Financeira Crítica e Sala de Aula invertida. Na parte II, detalhamos e produzimos vídeos instrucionais de todas as ferramentas digitais que utilizamos em nossa pesquisa, o Google Classroom, Google Meet, ApowerEdit, Youtube, Edpuzzle. Além disso, trouxemos, como exemplo, uma metodologia ativa, o mapa mental. E na última parte, trouxemos as atividades de Educação Financeira que realizamos em nossas aulas desse estudo.

Published: November 2022

O artigo objetiva encontrar alternativas para a viabilidade financeira da Reserva Particular do Patrimônio Natural (RPPN) Mata do Uru, pois para cumprir seus objetivos de conservação da biodiversidade são necessários investimentos financeiros e de capital humano, que nem sempre estão disponíveis aos responsáveis por sua gestão. O ecoturismo surge como potencialidade e referência, principalmente pela RPPN Mata do Uru estar localizada na Lapa (PR), um polo turístico relevante, com roteiros estabelecidos e infraestrutura implementada, bem como, a previsão da atividade no uso público em seu plano de manejo. Assim, a estrutura de organização do plano de uso público construído e proposto no âmbito deste artigo se consolida como instrumento norteador do processo futuro de inserção da RPPN neste campo, inclusive com possibilidade de replicar em diferentes contextos de gestão de RPPN. Envolvendo etapas de uma pesquisa bibliográfica, documental e de campo, a RPPN serviu de estudo de caso. Os dados coletados foram sistematizados a partir da técnica de triangulação de dados e análise de conteúdo.
Rosa y el canto inaudible: no- lugar, lugares de memoria y nexo voz-lugar

Published: November 2022

En base la experiencia de la cantora y educadora intercultural aymara Rosa Qhispi (Región de Tarapacá, norte de Chile) se aborda el vínculo entre canto y lugar en tres vertientes cruzadas.  La relativa al rol (lugar) tradicional de la cantora andina explicita su carencia de un lugar de enunciación, configurada por un silenciamiento histórico y estructural –perpetuado en la interculturalidad neoliberal– que determina su inaudibilidad. La geográfica, por su parte, refiere a la migración a la ciudad, el desarraigo y la situación de translocalidad que caracteriza a las y los sujetos aymaras en la región, en permanente tránsito entre los espacios urbanos y rurales. Por último, en la dimensión mnémica se propone a las prácticas musicales como lugares de memoria en cuanto instancias de recreación de la memoria colectiva que se activan en diferentes espacios y contextos, con distintos niveles de vinculación territorial. El disco, como lugar de memoria deslocalizado, constituye una herramienta fundamental al permitir a Rosa performar y proyectar su rol de acuerdo con sus propias nociones de tradición e interculturalidad. Los animales presentes en las canciones potencian el nexo voz-lugar del canto con la comunidad y la naturaleza.

Impact of COVID-19 Prevention and Control on the Influenza Epidemic in China: A Time Series Study
Authors: Guo Zirui , Zhang Li , Liu Jue , Liu Min
Published: November 2022

Background
. COVID-19 prevention and control measures might affect influenza epidemic in China since the nonpharmaceutical interventions (NPIs) and behavioral changes contain transmission of both SARS-CoV-2 and influenza virus. We aimed to explore the impact of COVID-19 prevention and control measures on influenza using data from the National Influenza Surveillance Network.
Methods
. The percentage of influenza-like illness (ILI%) in southern and northern China from 2010 to 2022 was collected from the National Influenza Surveillance Network. Weekly ILI% observed value from 2010 to 2019 was used to calculate estimated annual percentage change (EAPC) of ILI% with 95% confidence intervals (CIs). Time series analysis was applied to estimate weekly ILI% predicted values in 2020/2021 and 2021/2022 season. Impact index was used to explore the impact of COVID-19 prevention and control on influenza during nonpharmaceutical intervention and vaccination stages.
Results
. China influenza activity was affected by the COVID-19 pandemic and different prevention and control measures during 2020-2022. In 2020/2021 season, weekly ILI% observed value in both southern and northern China was at a low epidemic level, and there was no obvious epidemic peak in winter and spring. In 2021/2022 season, weekly ILI% observed value in southern and northern China showed a small peak in summer and epidemic peak in winter and spring. The weekly ILI% observed value was generally lower than the predicted value in southern and northern China during 2020-2022. The median of impact index of weekly ILI% was 15.11% in north and 22.37% in south in 2020/2021 season and decreased significantly to 2.20% in north and 3.89% in south in 2021/2022 season.
Conclusion
. In summary, there was a significant decrease in reported ILI in China during the 2020-2022 COVID-19 pandemic, particularly in winter and spring. Reduction of influenza virus infection might relate to everyday Chinese public health COVID-19 interventions. The confirmation of this relationship depends on future studies.

Interaction of intense laser fields with atoms distorts the bound-state electron cloud. Tracing the temporal response of the electron cloud to the laser field is of fundamental importance for understanding the ultrafast dynamics of various nonlinear phenomena of matter, but it is particularly challenging. Here, we show that the ultrafast response of the atomic electron cloud to the intense high-frequency laser pulses can be probed with the attosecond time-resolved photoelectron holography. In this method, an infrared laser pulse is employed to trigger tunneling ionization of the deforming atom. The shape of the deforming electron cloud is encoded in the hologram of the photoelectron momentum distribution. As a demonstration, by solving the time-dependent Schrödinger equation, we show that the adiabatic deforming of the bound-state electron cloud, as well as the nonadiabatic transition among the distorted states, is successfully tracked with attosecond resolution. Our work films the formation process of the metastable Kramers-Henneberger states in the intense high-frequency laser pulses. This establishes a novel approach for time-resolved imaging of the ultrafast bound-state electron processes in intense laser fields.

Abstract. The goal of the study was to investigate the effect of magnesium orotate as a part of complex therapy in sinus rhythm restoring in patients with AF paroxysm, as well as to evaluate its effectiveness and effect on LQo with long-term use.

Materials and research methods. We examined 56 patients (16 women and 40 men) with an average age of (61,5 ± 4,3) years with paroxysmal atrial fibrillation. All patients were divided into two groups. Patients of the 1st group (n=28) underwent medical cardioversion with amiodarone and magnesium orotate. Patients of the 2nd group (n=28) received only amiodarone. The time of sinus rhythm restoration, parameters of electrical instability of the atrial and ventricular myocardium after sinus rhythm restoration, patients life quality 3 months after discharge - were assessed in both groups.

Results. The study allowed to reveal that the addition of magnesium orotate to the basic therapy of patients with atrial fibrillation increases the effectiveness of medical cardioversion and reduces the time of its onset. When using amiodarone and magnesium orotate, signs of electrical instability of the atrial myocardium (the number of paired and supraventricular extrasystoles) are significantly less according to the results of Holter electrocardiogram monitoring compared with amiodarone monotherapy. Atrial fibrillation caused a life quality parameters deviations in the form of an increase in the severity of the disease symptoms, physical activity limitation and psycho-emotional sphere disorders. 3 months after the treatment, it was noted that life quality in patients of the 1st group (complex therapy using magnesium orotate) was higher compared to patients of the 2nd group due to the improvement in the indicators of the "psycho-emotional" component.

Conclusions. The addition of magnesium orotate to the basic therapy of paroxysmal atrial fibrillation can significantly improve the clinical course of the disease in patients and their life quality after 3 months treatment period.

The purpose of the work. Compare the effectiveness of PRP and general accepted methods of local therapy for long-term unhealed wounds in patients with diabetic foot syndrome.

Materials and methods. A study was performed in 33 long-term patients unhealed wounds on the foot and leg in the neuropathic form of diabetic foot syndrome. Patients were divided into two groups depending on the nature of the received therapies - PRP and local therapy according to generally accepted principles. The effectiveness of therapy was assessed by the nature of changes in the microflora and c wound cell composition, as well as wound surface area on the 1st day, 8th and 22nd after starting treatment.

Results. The use of PRP allowed to observe on the 8th day regenerative-inflammatory type of cytogram, have manifestations of vascularization and epithelialization, reduce the number of patients with infected wounds by 2.7 times and reducing the wound surface area by 1.7 cm, which is 3.4 times more than in the second group (0.5 cm). The introduction of the second dose of PRP is even more stimulating reparative changes in the wound, manifested by the regenerative type of cytogram, reducing the number of infected wounds by 8 times, and reducing the area wound surface 2 times from the first measurement, while in the second group only on the 22nd day there were positive changes that were characteristic of the first group on the 8th day.

Conclusion. Thus, the use of PRP in therapy is long unhealed wounds in diabetic foot syndrome, is a promising area of ​​regenerative therapy. PRP is a way to obtain a natural concentration of internal factors of growth with minimal invasiveness and low costs. Proposed method of biological therapy in such patients is simple and affordable for both patient and for the doctor.

Published: November 2022

Abstract. The search for new strategies for the correction of exogenous toxic liver lesions is due to the steady increase in the incidence of hepatitis and cirrhosis among the working population, which is an important medical and social problem.

The aim is to determine the effect of cryopreserved placenta extract (CEP) on the state of the liver of rats with tetrachloromethane (CCl4)-induced damage by indicators of lipid peroxidation (LP) and markers of cytolysis.

Materials and methods. Experimental studies were conducted on 28 male rats. Acute CCl4-induced hepatitis was reproduced by a single injection of 50.0% CCl4 oil solution. KEP was administered 1 time per day for 5 days before the introduction of CCl4. The material for the study was whole blood and liver homogenates, in which the content of reactants with thiobarbituric acid (TBA-RP), catalase activity, superoxide dismutase (SOD) activity, alanine aminotransferase (AlAt) and aspartate aminotransferase (AsAt) activity, as well as γ-glutamyl activity were determined. γ-glutamyl transpeptidases (γ-GTP) and alkaline phosphatase (AP) according to standard methods.

Results and discussion. The study showed that the content of TBA-RP in liver homogenates was lower (p<0.01) by 35.6% in rats that were prophylactically injected with CEP compared to rats with simulated CCl4-induced hepatitis without treatment (control group). An increase in the level of catalase (p=0.02) with the use of CEP was established by 33.8% and an increase in the activity of SOD (p<0.01) by 45.5% compared to the indicators of rats in the control group. It is also shown that the level of AlAt after administration of CEP decreased (p<0.001) by 56.0%, the level of AsAt decreased (p<0.001) by 48.6%, the level of γ-HTP decreased by 37.8% compared to the rats with untreated CCl4-induced hepatitis.

Conclusions. Prophylactic five-day administration of CEP leads to the leveling of CCl4-induced LP activation and signs of cytolysis syndrome.

Pada tahun 2020, Indonesia dilanda wabah COVID-19 yang disebabkan oleh virus SARSCoV-2 melalui kontak erat dan droplet. COVID-19 dapat menyebabkan penderitanya mengalami gangguan pernapasan akut, seperti demam, batuk, dan sesak napas. Pada gejala kasus COVID-19 yang berat, dapat menyebabkan pneumonia, sindrom pernapasan akut, gagal ginjal hingga kematian. Metode yang digunakan adalah penentuan alternatif masalah menggunakan beberapa tahapan, yaitu dengan membuat tujuan dari masing-masing alternatif yang ada serta disusun secara rinci dan tepat sehingga masing-masing dari alternatif masalah yang sudah ada dapat dilaksanakan dengan memperhatikan data informasi yang cukup dan metode perkiraan yang baik. Setelah dilakukan observasi, wawancara, dan analisis didapatkan bahwa masyarakat RW 002 Kelurahan Sawah Baru masih banyak yang belum menerapkan jaga jarak. Hal ini dikarenakan terjadi beberapa situasi atau kondisi tertentu di mana masyarakat lupa untuk menerapkan jaga jarak. Oleh karena itu, penulis membuat 3 program dengan tujuan untuk mengingatkan kembali masyarakat Kelurahan Sawah Baru terutama lingkungan RW 002 agar selalu menjaga jarak dan menerapkan protokol kesehatan lainnya. Berbagai kegiatan intervensi yang ada telah dikoordinasikan dan diintegrasikan dengan program yang dicanangkan oleh pihak Puskesmas Sawah Baru yang selanjutnya diharapkan dapat memberikan dampak khususnya berupa peningkatan penerapan jaga jarak agar dapat menurunkan laju persebaran COVID-19 yang cenderung meningkat kembali pada Februari tahun 2022.
