COVID-19 is a highly contagious respiratory disease with a high number of lethal cases in humans, which causes the need to search for new therapeutic agents. Polysaccharides could be one of the prospective types of molecules with a large variety of biological activities, especially antiviral. The aim of this work was to study the specific antiviral activity of the drug “Immeran” on a model of a new coronavirus infection SARS-CoV-2 in hamsters. Based on the second experiment, intraperitoneal treatment with the drug according to a treatment regimen in doses of 500 and 1000 μg/kg (administration after an hour, then once a day every other day, a total of 3 administrations) was effective, reliably suppressing the replication of the virus in the lungs and, at a dose of 1000 μg/kg, prevented weight loss in animals. In all cases, the treatment stimulated the formation of virus-neutralizing antibodies to the SARS-CoV-2 virus, which suggests that the drug possesses adjuvant properties.

Published: March 2024

During the COVID-19 pandemic, nonpharmaceutical interventions (NPIs) were implemented in order to control the transmission of SARS-CoV-2, potentially affecting the prevalence of respiratory syncytial virus (RSV). This review evaluated the impact of NPIs on RSV-related hospitalizations in children during the lockdown (2020–2021) compared to the pre-pandemic (2015–2020) and post-lockdown (2021–2022) periods. In this systematic review and meta-analysis, we searched through PubMed, Scopus, and Web of Science for studies published in English between 1 January 2015 and 31 December 2022. Additionally, we conducted hand searches of other records published between 1 January 2023 and 22 January 2024. Our target population was hospitalized children aged 0–18 years with RSV-related lower respiratory tract infections confirmed through immunofluorescence, antigen testing, or molecular assays. We focused on peer-reviewed observational studies, analyzing the primary outcome of pooled RSV prevalence. A generalized linear mixed model with a random-effects model was utilized to pool each RSV prevalence. Heterogeneity was assessed using Cochran’s Q and I2 statistics, while publication bias was evaluated through funnel plots and Egger’s tests. We identified and analyzed 5815 publications and included 112 studies with 308,985 participants. Notably, RSV prevalence was significantly lower during the lockdown period (5.03% [95% CI: 2.67; 9.28]) than during the pre-pandemic period (25.60% [95% CI: 22.57; 28.88], p < 0.0001). However, RSV prevalence increased notably in the post-lockdown period after the relaxation of COVID-19 prevention measures (42.02% [95% CI: 31.49; 53.33] vs. 5.03% [95% CI: 2.67; 9.28], p < 0.0001). Most pooled effect estimates exhibited significant heterogeneity (I2: 91.2% to 99.3%). Our findings emphasize the effectiveness of NPIs in reducing RSV transmission. NPIs should be considered significant public health measures to address RSV outbreaks.

Genomic sequencing of clinical samples to identify emerging variants of SARS-CoV-2 has been a key public health tool for curbing the spread of the virus. As a result, an unprecedented number of SARS-CoV-2 genomes were sequenced during the COVID-19 pandemic, which allowed for rapid identification of genetic variants, enabling the timely design and testing of therapies and deployment of new vaccine formulations to combat the new variants. However, despite the technological advances of deep sequencing, the analysis of the raw sequence data generated globally is neither standardized nor consistent, leading to vastly disparate sequences that may impact identification of variants. Here, we show that for both Illumina and Oxford Nanopore sequencing platforms, downstream bioinformatic protocols used by industry, government, and academic groups resulted in different virus sequences from same sample. These bioinformatic workflows produced consensus genomes with differences in single nucleotide polymorphisms, inclusion and exclusion of insertions, and/or deletions, despite using the same raw sequence as input datasets. Here, we compared and characterized such discrepancies and propose a specific suite of parameters and protocols that should be adopted across the field. Consistent results from bioinformatic workflows are fundamental to SARS-CoV-2 and future pathogen surveillance efforts, including pandemic preparation, to allow for a data-driven and timely public health response.

Porcine epidemic diarrhea virus (PEDV) has affected the pork industry worldwide and during outbreaks the mortality of piglets has reached 100%. Lipid nanocarriers are commonly used in the development of immunostimulatory particles due to their biocompatibility and slow-release delivery properties. In this study, we developed a lipid nanoparticle (LNP) complex based on glycyrrhizinic acid (GA) and tested its efficacy as an adjuvant in mice immunized with the recombinant N-terminal domain (NTD) of porcine epidemic diarrhea virus (PEDV) spike (S) protein (rNTD-S). The dispersion stability analysis (Z-potential −27.6 mV) confirmed the size and charge stability of the LNP-GA, demonstrating that the particles were homogeneously dispersed and strongly anionic, which favors nanoparticles binding with the rNTD-S protein, which showed a slightly positive charge (2.11 mV) by in silico analysis. TEM image of LNP-GA revealed nanostructures with a spherical-bilayer lipid vesicle (~100 nm). The immunogenicity of the LNP-GA-rNTD-S complex induced an efficient humoral response 14 days after the first immunization (p < 0.05) as well as an influence on the cellular immune response by decreasing serum TNF-α and IL-1β concentrations, which was associated with an anti-inflammatory effect.

This study examines the vaccine market access pathway in Poland to evaluate its efficiency and propose recommendations for its improvement. The research spans a comprehensive analysis of the vaccine assessment process, ranging from pre-registration to sustainability, encompassing critical components such as national immunization technical advisory groups (NITAGs), health technology assessments, resource evaluations, and decision making. This investigation utilizes a multi-phase approach. Initial desk research aimed to collect accumulated evidence about each step of the vaccine access pathway. This constituted the background for an expert panel discussion (n = 13) and a final online questionnaire (n = 12), evaluating the timeframes, inclusiveness, transparency, and consistency of the elements of the process. Poland is a late adopter of new vaccines. The country faces budget constraints and lacks a formalized framework for the inclusion of vaccines into the national immunization program. Notably, NITAGs play a crucial role, yet their limited resources and dependence on public health stakeholders diminish their impact. A formal and well-supported advisory body may become a foundation for decision-making processes. The health technology assessment conducted by the national agency is recognized for its timeliness and transparency, though the absence of fiscal analyses in vaccine assessments is identified as a gap that limits the understanding of the value of vaccinations. Resources are key drivers of decision making, and recent changes in legislation offer increased flexibility in financing vaccines. Challenges in the procurement process include a limited consideration of non-acquisition costs and an increased absence of a documented general strategy for immunization program development in Poland, pointing to a need for strategic planning. In conclusion, this study recommends the establishment of a robust NITAG with enhanced resources, incorporating fiscal analyses, transparent resource allocation, and strategic planning for immunization program development. Addressing these recommendations is crucial for optimizing Poland’s vaccine market access pathway, ensuring timely and efficient population-wide vaccine access.
Motion Capture in Mixed-Reality Applications: A Deep Denoising Approach
Authors: Gonçalves André Correia , Jesus Rui , Jorge Pedro Mendes
Published: March 2024

Motion capture is a fundamental technique in the development of video games and in film production to animate a virtual character based on the movements of an actor, creating more realistic animations in a short amount of time. One of the ways to obtain this movement from an actor is to capture the motion of the player through an optical sensor to interact with the virtual world. However, during movement some parts of the human body can be occluded by others and there can be noise caused by difficulties in sensor capture, reducing the user experience. This work presents a solution to correct the motion capture errors from the Microsoft Kinect sensor or similar through a deep neural network (DNN) trained with a pre-processed dataset of poses offered by Carnegie Mellon University (CMU) Graphics Lab. A temporal filter is implemented to smooth the movement, given by a set of poses returned by the deep neural network. This system is implemented in Python with the TensorFlow application programming interface (API), which supports the machine learning techniques and the Unity game engine to visualize and interact with the obtained skeletons. The results are evaluated using the mean absolute error (MAE) metric where ground truth is available and with the feedback of 12 participants through a questionnaire for the Kinect data.

Authors: Zheng Yang , Meng Long , Zhang Guang , Xue Peng , Wang Xin , Zhang Chiye , Tian Yajuan
Published: March 2024

The benefits of variable speed centrifugal pumps include high stability, a broad operating range, and adjustable input power. In water distribution systems, the pump units are increasingly using variable speed technology. The energy-saving features and operational stability of the pump station are directly impacted by the hydraulic performance and the operation strategy. In this study, CFD numerical analysis and model tests were adopted to design and evaluate the hydraulic performance of the variable speed centrifugal pump with large flow and wide head variation in Liyuzhou Pump Station. Under the premise of ensuring the wide head variation, the optimized centrifugal pump met the requirements of hump margin and efficiency in the high head zone and the cavitation margin in the low head zone. The test results demonstrated that the operational range of the variable speed centrifugal pump was successfully widened by reasonable hydraulic parameters selection and impeller optimization. The safe and efficient operational range of the variable speed unit was determined by means of taking the performance requirements of the pump’s maximum input shaft power, cavitation characteristics and pressure fluctuation into consideration. The scientific and reasonable operational path to meet the various operation needs was also investigated and determined for the pump station’s actual operation needs. A high efficiency, safe operation, and a simplified control logic were achieved by using the operational path, which makes it a reasonable potential guide for hydraulic design and operational optimization of variable speed centrifugal pumps with large flow and wide head range.

Authors: Fabregat Víctor , Pagán Juana María
Published: March 2024

The focus on emerging contaminants (ECs) in wastewater has intensified due to the considerable risks they present to human health and wildlife. This paper presents the results of the technical–economic assessment of the Clean Up solution, carried out in the framework of the project entitled “Validation of Adsorbent Materials and Advanced Oxidation Techniques to Remove Emerging Pollutants in Treated Wastewater”. The viability of the Clean Up system is evaluated by being applied as an advanced treatment system for treated urban wastewater, that is, for the elimination of pathogens and emerging pollutants (EPs), while considering the established quality criteria by current regulations. In this sense, it is a technology that has been successfully validated at an experimental level, and that offers similar removal performance compared to that of the most efficient alternatives available on the market. The technical–economic assessment has been conducted through a systematic process. Initially, the estimation involved the calculation of treatment costs for the Clean Up system when applied at an industrial scale. Subsequently, the treatment costs were estimated for the most favorable technological alternative to the Clean Up system from a technical–economic standpoint, also applied at an industrial scale, within identical scenarios and conditions as those assumed for the Clean Up system. The final step involved a comprehensive comparison of treatment costs between both alternatives, implemented uniformly under analogous conditions and assumed similar performance across all cases.

An Examination of Identity and Colonialism in Tayeb Saleh's Season of Migration to the North through the Lens of Frantz Fanon's Black Skin, White Masks A Comparative Study
Authors: Bah Adama
Published: March 2024

"In the exploration of post-colonial literature, Tayeb Saleh's 'Season of Migration to the North' and Frantz Fanon's 'Black Skin, White Masks' emerge as pivotal works that intricately dissect the complex interplay between identity and colonialism. Both authors delve into the psychological ramifications of colonial histories on individual identities, unraveling the multifaceted layers of the post-colonial experience. The themes of identity and colonialism in Tayeb Salih's "Season of Migration to the North" through the lens of Frantz Fanon's seminal work, "Black Skin, White Masks." By examining the experiences of the protagonist, Mustafa Sa'eed, who returns to Sudan after studying in England, the essay delves into the complex ways in which colonial encounters shape individual identity. Drawing on Fanon's theories, particularly the concepts of double consciousness and the psychological effects of colonization, the analysis sheds light on the psychological and cultural impact of the colonial experience on Sa'eed and other characters in the novel. This article investigates the idea of cultural hybridity and the ambivalence that arises from navigating multiple cultural influences. Moreover, it explores the gender dynamics present in both works, emphasizing the power imbalances and objectification of women within the colonial context. Through a comparative analysis, the article seeks to highlight the characters' struggles for authentic selfhood and the broader implications of their experiences in a post-colonial world. Ultimately, this exploration provides insights into the enduring relevance of these themes and the intricate interplay between identity and colonialism in literature. The present   article seeks to examine the nuanced ways in which Saleh's narrative and Fanon's psychoanalytic insights intersect, offering a profound understanding of the profound impact of colonialism on the construction and negotiation of identity in a post-colonial world."

Tayeb Salih's novel, Season of Migration to the North, delves into the intricate relationships that exist between colonialism and identity in post-colonial Sudan. In close resemblance to Frantz Fanon's groundbreaking work Black Skin, White Masks, the article explores the novel's complex concerns of identity building, cultural hybridity, and the psychological effects of colonialism in African literature. By their audacious writings, Fanon and Salih both transformed the postcolonial African landscape. Using a postcolonial perspective, this study investigates how the story's characters navigate their cultural heritage and sense of self in the years after colonial domination.

Der auch schon von Huizinga beobachtete Spielverlust in unseren Gesellschaften, der sich heute noch verschärft darstellt, würde besondere Aufmerksamkeit in der Sozialisation und im Erziehungssystem benötigen. Jedoch hat das Spiel zusehends die zwar funktionale, aber miniaturisierte Rolle, andere Kulturtechniken zu unterstützen. Im Beitrag werden die kulturellen, sozialen und rituellen Strukturen des Spiels untersucht, die mit der Ermöglichung von Exploration verbunden sind, und die sein Potenzial für Lernen und Bildung ausmachen, wobei die Spielfähigkeit selbst als die entscheidende Kulturtechnik in den Blick kommt. Es wird untersucht, wie die Exploration im Spiel unter Kindern sich strukturiert, und welche kulturellen und individuellen Motive bei der Begleitung des Spiels durch die Lehrpersonen dazu führen können, dass es oftmals eher zur Disziplinierung des Spiels kommt als zur erfahrungsbasierten, gleichrangigen Auseinandersetzung. Alternativen werden skizziert. (DIPF/Orig.)

We report on a high-power Er3+-doped yttrium aluminum perovskite (Er:YAP) laser system run by incoherent beam combining at RT. A stable continuous-wave (CW) laser beam at 2.92 μm with an average power of 8.2 W is generated. To the best of our knowledge, this is the highest average power achieved from CW Er3+-doped solid-state lasers above 2.9 μm. No power saturation is observed, indicating that the output power can be further scaled up. Moreover, the experimental results show that the beam quality is maintained during the beam combining process.
Challenges in collecting age composition data from commercial catches of the Barents sea bottom fishes
Authors: Kovalev Yu. A. , Yaragina N. A. , Chetyrkin A. A.
Published: March 2024

The paper presents the rationale for collecting information on the structure of catches and the distribution of bottom fish species (and in particular North-East Arctic cod) on fishing vessels in the Barents Sea and adjacent waters by observers of the Polar Branch of FSBSI «VNIRO» («PINRO» named after N.M. Knipovich). The problems that arise during the work of a scientific observer are described. Possible solutions to solve the problems of collecting materials on commercial catches are proposed. Increase of the scientific observers number on bottom fish fisheries and elevation of their legal status is recommended. A fundamentally new scheme for collecting information on the size distribution of fish in commercial catches by the crews of fishing vessels has been proposed.

To differentiate Sakhalin saffron cod, 3 types of parasites can be used: Pyramicocephalus phocarum pl., Nybelinia surmenicola pl. and Echinorhynchus gadi. From a practical point of view, as a biological label for the differentiation of the navaga hall. It is advisable to use indicators of infection with Nybelinia surmenicola l in the south-east of Sakhalin and the north-west of the island. To determine the location of the catch of the navaga (applicable only for the areas of the north-west, south-east of Sakhalin and zal. Patience) it is necessary to examine at least 100 specimens of fish.
Printing School Democracy from Below: Student Press Activities as Collective Action in Mid-Post-War Sweden
Authors: Lövheim Daniel
Published: March 2024

This article deals with the growth of a national school student press in Sweden during the 1950s and first half of the 1960s. It outlays the role of student magazines in furthering school democracy by investigating the nationwide periodical SECO-aktuellt and the press organisation SVEP (Svensk Elevpress). The article departs from an understanding of press activity among school youth as a form of collective action during the mid-post-war period. This activity became part of a pupil movement that demanded increased influence and participation in decision making, as well as expanded forms of self-government. Drawing from earlier historical research, the article portrays this press activity as taking place “from below” since youth often was marginalised in the past and not always seen as legitimate historical actors. The article also deploys perspectives from research on social movements, and analyses school student press activities in Sweden as “repertoires of contention.”
