Young Flexitarians: An Insight into Barriers and Facilitators Related to Capability, Opportunity, and Motivation for Meat Reduction
Authors: Vezovnik Andreja , Kamin Tanja
Published: October 2024

In recent decades, meat consumption has faced growing scrutiny from an environmental, health, and animal welfare perspective. As a result, reducing meat consumption has emerged as an important strategy to mitigate its negative effects. Flexitarians, a growing group of meat reducers, have attracted attention for potentially shaping future dietary trends. This study uses a qualitative approach and draws on 15 in-depth interviews with young flexitarians in Slovenia (YFS) to identify the main facilitators and barriers to meat reduction by exploring their motivations, capabilities, and opportunities as described in the COM-B behavioral model. This study fills the gap in studies on flexitarians using the COM-B model by looking at capabilities and opportunities, not solely motives. In addition, it fills the gap in qualitative in-depth studies on all three COM-B categories, as well as a gap in studies conducted outside northwest Europe and other primarily western geographical contexts. This study highlights important findings for the central and eastern European context that industry and governments should consider when developing behavior change strategies for healthy, sustainable diets. This study shows that strong rural family ties and limited access to meat alternatives are the major barriers to meat reduction in Slovenia. The YFS preferred whole, unprocessed foods (legumes, vegetables, grains) over processed meat alternatives and reduced their meat consumption primarily for health and environmental reasons, relying on social support from peers and information from popular documentaries and social media influencers.

Authors: Song Pucha , Ye Jinghua , Yan Kang , Luo Zhengyan
Published: October 2024

Using adaptive filtering to estimate the frequency of power systems has become a popular trend. In recent years, however, few studies have been performed on adaptive frequency estimations in non-stationary noise environments. In this paper, we propose the distributed complex inverse square root algorithm and distributed augmented complex inverse square root algorithm for the frequency estimation of power systems based on the widely linear model and the inverse square root cost function, where the function can restrain both positive and negative large errors, based on its symmetry. Moreover, the wireless sensor networks support monitoring and adaptation for the frequency estimation in the distributed networks, and the proposed approach can ensure good robustness of the balanced or unbalanced three-phase power system with the help of a local complex-value voltage signal generated by Clark’s transformation. In addition, the bound of step size is driven by the global vectors, and that low computation complexity do not hinder those performances. The results of several experiments demonstrate that our algorithms can effectively estimate the frequency in impulsive noise environments.

Authors: Šimenko Jožef , Sertić Hrvoje , Segedi Ivan , Čuk Ivan
Published: October 2024

(1) Background: The advancement of technologies has made morphological assessment rapid and reliable. A combination of 3D body scanning (3D-BS) and bioelectrical impedance (BIA) could be essential in monitoring the morphological status of athletes and the general population and their symmetries for coaches, researchers and medical professionals. (2) Methods: The current study presents the use of Inbody-720 BIA and 3D-BS NX-16 for analyzing the asymmetry profile of an athlete in 2 min on a sample of 106 male judo competitors from the following age categories: older boys—U14 (N = 24), younger cadets—U16 (N = 31), cadets—U18 (N = 17), juniors—U21 (N = 19) and seniors (N = 15). Variables observed were arm lean mass, upper arm, elbow, forearm and wrist girth, leg lean mass, thigh length, thigh, knee and calf girth. The paired sample t-test, asymmetry index (AI) and Kruskal–Wallis analysis were used at p ≤ 0.05; (3) Results: Morphological asymmetries were detected in all age categories: seniors—three, U21—four, U18—three, U16—five and U14—four. The most common asymmetrical variable in all categories was the forearm girth, while thigh length, knee girth and upper arm girth presented symmetrical variables in all age categories. AI showed that the size of the asymmetries did not differentiate between the age groups. (4) Conclusions: The current study demonstrated great potential for combining BIA and 3D-BS for rapid asymmetry detection that would allow for monitoring and quick adjustments to the training process in youth to senior age categories.

Authors: Cavada Marianna , Kwon Nuri , Cooper Rachel
Published: October 2024

The smart city concept has garnered a lot of interest; however, it often falls short when it comes to providing clarity on the benefits it can offer. Discussing smartness in the context of cities and their inhabitants requires the involvement of a wide range of stakeholders in decision-making. Similarly, the decision-making process is often unclear and can lack integrity. For this reason, in this research, we clarify this process and establish a smart agenda for urban areas. Specifically, this study focusses on the existing research in truly smart cities (where liveability is at the heart of decision-making). The research team implemented the assessment model (SMART) during a facilitated workshop under COVID-19 restrictions. Taking societal, environmental, health, economic, and governance liveability perspectives into account, the results yielded a set of recommendations for designing the smart urban agenda, which can support cities that aspire to become smart.

Minimally Modified HIV-1 Infection of Macaques: Development, Utility, and Limitations of Current Models
Authors: Sharma Manish , Nag Mukta , Del Prete Gregory Q.
Published: October 2024

Nonhuman primate (NHP) studies that utilize simian immunodeficiency virus (SIV) to model human immunodeficiency virus (HIV-1) infection have proven to be powerful, highly informative research tools. However, there are substantial differences between SIV and HIV-1. Accordingly, there are numerous research questions for which SIV-based models are not well suited, including studies of certain aspects of basic HIV-1 biology, and pre-clinical evaluations of many proposed HIV-1 treatment, prevention, and vaccination strategies. To overcome these limitations of NHP models of HIV-1 infection, several groups have pursued the derivation of a minimally modified HIV-1 (mmHIV-1) capable of establishing pathogenic infection in macaques that authentically recapitulates key features of HIV-1 in humans. These efforts have focused on three complementary objectives: (1) engineering HIV-1 to circumvent species-specific cellular restriction factors that otherwise potently inhibit HIV-1 in macaques, (2) introduction of a C chemokine receptor type 5 (CCR5)-tropic envelope, ideally that can efficiently engage macaque CD4, and (3) correction of gene expression defects inadvertently introduced during viral genome manipulations. While some progress has been made toward development of mmHIV-1 variants for use in each of the three macaque species (pigtail, cynomolgus, and rhesus), model development progress has been most promising in pigtail macaques (PTMs), which do not express an HIV-1-restricting tripartite motif-containing protein 5 α (TRIM5α). In our work, we have derived a CCR5-tropic mmHIV-1 clone designated stHIV-A19 that comprises 94% HIV-1 genome sequence and replicates to high acute-phase titers in PTMs. In animals treated with a cell-depleting CD8α antibody at the time of infection, stHIV-A19 maintains chronically elevated plasma viral loads with progressive CD4+ T-cell loss and the development of acquired immune-deficiency syndrome (AIDS)-defining clinical endpoints. However, in the absence of CD8α+ cell depletion, no mmHIV-1 model has yet displayed high levels of chronic viremia or AIDS-like pathogenesis. Here, we review mmHIV-1 development approaches, the phenotypes, features, limitations, and potential utility of currently available mmHIV-1s, and propose future directions to further advance these models.

Erwinia amylovora, the causative agent of fire blight, causes significant economic losses for farmers worldwide by inflicting severe damage to the production and quality of plants in the Rosaceae family. Historically, fire blight control has primarily relied on the application of copper compounds and antibiotics, such as streptomycin. However, the emergence of antibiotic-resistant strains and growing environmental concerns have highlighted the need for alternative control methods. Recently, there has been a growing interest in adopting bacteriophages (phages) as a biological control strategy. Phages have demonstrated efficacy against the bacterial plant pathogen E. amylovora, including strains that have developed antibiotic resistance. The advantages of phage therapy includes its minimal impact on microbial community equilibrium, the lack of a detrimental impact on plants and beneficial microorganisms, and its capacity to eradicate drug-resistant bacteria. This review addresses recent advances in the isolation and characterization of E. amylovora phages, including their morphology, host range, lysis exertion, genomic characterization, and lysis mechanisms. Furthermore, this review evaluates the environmental tolerance of E. amylovora phages. Despite their potential, E. amylovora phages face certain challenges in practical applications, including stability issues and the risk of lysogenic conversion. This comprehensive review examines the latest developments in the application of phages for controlling fire blight and highlights the potential of E. amylovora phages in plant protection strategies.

Published: October 2024

Modified vaccinia Ankara (MVA) virus is a widely used vaccine platform, making accurate titration essential for vaccination studies. However, the current plaque forming unit (PFU) assay, the standard for MVA titration, is prone to observer bias and other limitations that affect accuracy and precision. To address these challenges, we developed a new flow cytometry-based quantification method using a highly specific monoclonal antibody (mAb) for the detection of MVA-infected cells, as a more accurate titration assay. Through previous work, we serendipitously identified three MVA-specific hybridoma antibody clones, which we characterized through ELISA, immunoblot, and flow cytometry, confirming their specificity for MVA. Sequencing confirmed that each antibody was monoclonal, and mass spectrometry results revealed that all mAbs target the MVA cell surface binding protein (CSBP, MVA105L). We next optimized the titration protocol using the most effective mAb, 33C7 by refining culture conditions and staining protocols to enhance sensitivity and minimize background. Our optimized method demonstrated superior sensitivity, reliability, and reduced processing time when compared with the traditional PFU assay, establishing it as a more accurate and efficient approach for MVA titration.

Published: October 2024

Background: HPV vaccination is the key measure to prevent cervical cancer, but uptake in China lags behind global targets. Understanding Chinese guardians’ preferences is key to improving vaccine acceptance and coverage. Methods: A nationwide online discrete choice experiment survey was conducted among 4933 Chinese guardians across seven provinces in 2022 to quantify preferences and willingness to pay. Attributes included effectiveness, safety, duration, valency, location, and out-of-pocket cost. Results: Out of the 4933 guardians who participated in the study, 4179 (84.72%) were mothers. More than 60% of the guardians belonged to the age group of 35–44 years. Additionally, over half of the respondents (53.15%) had daughters between the ages of 9 and 14 years. Respondents were open to accepting the HPV vaccine with 95% efficacy and exceptional safety. Guardians expressed a preference for longer protection duration (specifically 15 years (βa = 0.340, 95% CI: 0.31, 0.37)) and higher vaccine valency. As for willingness to pay, the respondents placed the highest value on vaccine efficacy, being willing to shell out more than USD 1100 for 95% protection as compared to 50%. Furthermore, very good safety commanded a premium of over USD 800 when compared to average safety. When it comes to willingness to uptake, a vaccine with 95% efficacy led to a more than 35% increase in acceptance as compared to one with 50% efficacy. Similarly, exceptional safety resulted in an increased willingness to uptake of over 25% when compared to average safety. Conclusions: The DCE highlighted effectiveness, safety, and durability as critical drivers of HPV vaccine acceptance, but substantial barriers persist regarding adolescent female coverage in China.

Published: October 2024

Background: Haemonchus contortus (H. contortus), a nematode with global prevalence, poses a major threat to the gastrointestinal health of sheep and goats. In an effort to combat this parasite, a nanovaccine was created using a recombinant ADP-ribosylation factor 1 (ARF1) antigen encapsulated within poly lactic-co-glycolic acid (PLGA). This study aimed to assess the effectiveness of this nanovaccine in providing protection against H. contortus infection. Methods: Fifteen goats were randomly divided into three groups. The experimental group received two doses of the PLGA encapsulated rHcARF1 (rHcARF1-PLGA) nanovaccine on days 0 and 14. Fourteen days after the second immunization, both the experimental and positive control groups were challenged with 8000 infective larvae (L3) of H. contortus, while the negative control group remained unvaccinated and unchallenged. At the end of the experiment on the 63rd day, all animals were humanly euthanized. Results: The results showed that the experimental group had significantly higher levels of sera IgG, IgA, and IgE antibodies, as well as increased concentrations of cytokines, such as IL-4, IL-9, IL-17, and TGF-β, compared to the negative control group after immunization. Following the L3 challenge, the experimental group exhibited a 47.5% reduction in mean eggs per gram of feces (EPG) and a 55.7% reduction in worm burden as compared to the positive control group. Conclusions: These findings indicate that the nanovaccine expressing rHcARF1 offers significant protective efficacy against H. contortus infection in goats. The results also suggest the need for more precise optimization of the antigen dose or a reassessment of the vaccination regimen. Additionally, the small sample size limits the statistical rigor and the broader applicability of the findings.
Impact of Immunosuppressants and Vaccination on COVID-19 Outcomes in Autoimmune Patients and Solid Organ Transplant Recipients: A Nationwide Propensity Score-Matched Study
Authors: Sung Mindong , Kim Young-Sam , Cho Changjin , Son Yongeun , Kim Dong-Wook , Lee Su-Hwan
Published: October 2024

Purpose: This study investigates the impact of varying degrees of immunosuppression on the clinical outcomes of immunocompromised individuals, particularly those with autoimmune diseases or post-solid organ transplant statuses, in the context of COVID-19. By focusing on these highly vulnerable populations, the study underscores the significant health inequalities faced by immunocompromised patients, who experience disproportionately worse outcomes in comparison to the general population. Methods: A retrospective cohort analysis of the K-COV-N dataset was conducted, comparing the effects of immunosuppression in autoimmune and transplant groups with matched control groups. Propensity score matching was employed to minimize inequalities in baseline characteristics, ensuring a more equitable comparison between immunocompromised and non-immunocompromised individuals. Outcomes included COVID-19-related in-hospital mortality, 28-day mortality, ICU admissions, and the need for respiratory support among 323,890 adults in the Republic of Korea. Patients with cancer or other immunosuppressive conditions, such as HIV, were excluded. Subgroup analyses assessed the influence of specific immunosuppressive medications and vaccination extent. Results: Significantly elevated in-hospital mortality was found for patients with autoimmune diseases (adjusted Odds Ratio [aOR] 2.749) and transplant recipients (aOR 7.567), with similar patterns in other outcomes. High-dose steroid use and a greater number of immunosuppressant medications markedly increased the risk of poor outcomes. Vaccination emerged as a protective factor, with a single dose substantially improving outcomes for autoimmune patients and at least two doses necessary for transplant recipients. Conclusions: Immunocompromised patients, particularly those with autoimmune diseases and transplant recipients, are highly vulnerable to severe COVID-19 outcomes. High-dose steroid use and multiple immunosuppressants further increase risks. Vaccination significantly improves outcomes, with at least one dose benefiting autoimmune patients and two doses necessary for transplant recipients. Personalized vaccination schedules based on immunosuppression levels are essential to mitigate healthcare inequalities and improve outcomes, particularly in underserved populations, informing both clinical and public health strategies.

Published: October 2024

The study aimed to assess the agreement between OptoTab SERIES, alternating Cover Test, Modified Thorington test, and Von Graefe method in measuring heterophoria and accommodative convergence over accommodation (AC/A) ratio. In an initial step, heterophoria was assessed at both distance and near in a cohort of 76 healthy young volunteers using the previously described tests. Subsequently, to determine the AC/A ratio, near-vision measurements were repeated with +1.00 D and −1.00 D lenses. All tests were performed in a randomized order across participants under consistent conditions. Significant differences were found between the Modified Thorington test and all other tests at distance (Wilcoxon test, all p ≤ 0.001) and between Von Graefe and all other tests at near (Wilcoxon test, all p ≤ 0.005). Regarding the AC/A ratio, significant differences were observed between all methods in +1.00 D AC/A ratio, except for the Modified Thorington test vs. the alternating Cover Test (Wilcoxon test, p = 0.024). In the −1.00 D AC/A ratio, differences were observed between OptoTab POCKET and all the other tests (Wilcoxon test, all p ≤ 0.001). The results indicate that all methods are interchangeable except the Modified Thorington test at distance and Von Graefe at near. For the AC/A ratio, only the Modified Thorington test is interchangeable with the alternating Cover Test using +1.00 D lenses and all are interchangeable using −1.00 D lenses except OptoTab POCKET.
Insurance Coverage and Flood Exposure in the Gulf of Mexico: Scale, Social Vulnerability, Urban Form, and Risk Measures
Authors: Hyde Anissa , Habans Robert , Valladares-Castellanos Mariam , Douthat Thomas
Published: October 2024

Increasing flood losses in the Gulf of Mexico related to development patterns and climate hazards pose serious threats to resilience and insurability. The purpose of this study is to understand how scale, social vulnerability, risk, and urban form relate to National Flood Insurance Program (NFIP) policy coverage and flood exposure. Our multilevel models identify that flooding is significantly clustered by region and counties, especially shoreline counties. Our measures of risk suggest that the Federal Emergency Management Agency (FEMA) special flood hazard area (SFHA) underestimates risk and exposure when compared with the Flood Factor and that there is some compensation in terms of insurance coverage, suggesting a pattern of adverse selection. Older housing stock appears both less insured and less exposed, raising questions of whether current growth patterns are increasing risk independent of environmental change. Our models suggest that census tracts with higher percentages of black residents are less insured and more exposed, and a similar pattern exists for rural areas. Our results highlight the need to seek common solutions across the Gulf of Mexico, concentrating on the most flood-exposed counties, and that specific resilience strategies may be necessary to protect areas with socially vulnerable populations, especially in rural areas. Underlying challenges exist due to the spatial relationship between exposure and social vulnerability and the potential for adverse selection in insurance markets due to different measures of risk.
Optimization of Water Distribution Network Demand Patterns Using Real-Coded Genetic Algorithms
Authors: Kim Dong-Hwi , Jang Dong-Woo
Published: October 2024

The penetration rate of water supply via water supply facilities in the Republic of Korea has reached 99%, with 94% of the energy for operation consumed by pumps transporting water. Consequently, developing efficient pump operation techniques is crucial for reducing energy costs in water supply systems. This study employs real-coded genetic algorithm techniques to compute optimized demand patterns, considering the utilization of water tanks within networks. Hydraulic appropriateness is verified by evaluating pressure within nodes determined by derived patterns through numerical analysis simulations. Furthermore, after calculating flows supplied to the networks, pump power is determined, and resultant energy costs are estimated to evaluate economic feasibility. Results indicate that pressure distribution in networks with optimal patterns is hydraulically appropriate, meeting hydrodynamic pressure conditions suggested in water supply design standards. Additionally, this study demonstrates a 9% reduction in network energy costs compared to existing patterns. The model presented herein offers a means to efficiently operate water supply systems through water tanks, thereby reducing energy costs.

Published: October 2024

The independence of students in elementary schools is considered to be still low, because many students are still dependent on teachers for learning, and friends who are more brilliant in doing questions. The culture of cheating when taking exam questions reflects that students do not have confidence in their abilities. This research aims to provide a description of the use of the Wordwall application as a learning medium for Natural and Social Sciences (IPAS) in cultivating the independent character of students in elementary schools. Researchers used descriptive qualitative research with data sources from interviews, observation and documentation. The data obtained was then narrated to get a general overview of the application of the Wordwall application in cultivating the independent character of Bustanul Ulum Islamic Elementary School students. The results of the research show that there is a change in attitude that occurs after using learning media in the form of the Wordwall application. Changes can be seen from students' activeness during the learning process, and the reduced habit of asking more brilliant friends when doing questions and exams. Educators are expected to be able to innovate and think creatively with existing features as alternative learning media to achieve learning goals, one of which is the formation of student character.

Published: October 2024

Одной из глобальных проблем городского хозяйства является обеспечение комфортности проживания людей, где наибольшее внимание должно уделяться таким аспектам, как чистота воды и воздуха. Изучению и оценке подлежит нормативно-техническая документация по анализу городской воздушной среды и сточных вод, транспортируемых по самотечным водоотводящим сетям, в подсводном пространстве которых наблюдается наличие дурнопахнущих газов. Рассмотрены источники загрязнения вредными для здоровья человека запахами, являющимися результатом протекания интенсивных биохимических процессов в безнапорных сетях, а также проанализированы мероприятия, позволяющие снизить или ликвидировать пагубные последствия вредных для здоровья человека газов. Проведен аналитический обзор результатов потенциального анализа проб сточной воды и воздуха, содержащегося в подсводном пространстве водоотводящих сетей. Отмечено, что некоторые виды микроорганизмов, находящихся в замкнутом воздушном пространстве канализационных колодцев, способны оказывать негативное воздействие на человеческий организм, что представляет угрозу здоровью обслуживающему персоналу водоотводящих сетей при проведении им работ в колодцах без средств индивидуальной защиты дыхательных путей. Рассмотрены химические, механические и гидродинамические методы нейтрализации веществ, провоцирующих появление запахов.

One of the global tasks of the municipal services is to ensure comfortable living conditions for people, for which purpose the greatest attention should be paid to such aspects as clean water and air. The regulatory and technical documentation on the analysis of the urban air and wastewater transported through gravity sewers with malodorous gases present in the underroof space, are subject to study and assessment. The sources of pollution with odors detrimental to human health that result from the intensive biochemical processes in gravity networks are considered, as also measures are analyzed to reduce or eliminate the harmful effects of gases detrimental to human health. An analytical review of the results of potential analysis of samples of wastewater and air in the underroof space of sewers was conducted. It was noted that some types of microorganisms present in the enclosed airspace of sewer manholes could produce a negative impact on the human body, i.e. pose health risks to the maintenance staff of sewer networks while working in manholes without individual respiratory protective means. Chemical, mechanical and hydrodynamic methods for neutralizing substances that provoke the appearance of malodors are considered.
