West Nile Virus (WNV) poses a significant global public health threat as a mosquito-borne pathogen. While laboratory mouse models have historically played a crucial role in understanding virus biology, recent research has focused on utilizing immunocompromised models to study arboviruses like dengue and Zika viruses, particularly their interactions with Aedes aegypti mosquitoes. However, there has been a shortage of suitable mouse models for investigating WNV and St. Louis encephalitis virus interactions with their primary vectors, Culex spp. mosquitoes. Here, we establish the AG129 mouse (IFN α/β/γ R−/−) as an effective vertebrate model for examining mosquito–WNV interactions. Following intraperitoneal injection, AG129 mice exhibited transient viremia lasting several days, peaking on the second or third day post-infection, which is sufficient to infect Culex quinquefasciatus mosquitoes during a blood meal. We also observed WNV replication in the midgut and dissemination to other tissues, including the fat body, in infected mosquitoes. Notably, infectious virions were present in the saliva of a viremic AG129 mouse 16 days post-exposure, indicating successful transmission capacity. These findings highlight the utility of AG129 mice for studying vector competence and WNV–mosquito interactions.

Authors: Rai Chung-I , Kuo Tsu-Hsiang , Chen Yuan-Chuan
Published: September 2024

Traditional vaccines can be classified into inactivated vaccines, live attenuated vaccines, and subunit vaccines given orally or via intramuscular (IM) injection or subcutaneous (SC) injection for the prevention of infectious diseases. Recently, recombinant protein vaccines, DNA vaccines, mRNA vaccines, and multiple/alternative administering route vaccines (e.g., microneedle or inhalation) have been developed to make vaccines more secure, effective, tolerable, and universal for the public. In addition to preventing infectious diseases, novel vaccines have currently been developed or are being developed to prevent or cure noninfectious diseases, including cancer. These vaccine platforms have been developed using various biotechnologies such as viral vectors, nanoparticles, mRNA, recombination DNA, subunit, novel adjuvants, and other vaccine delivery systems. In this review, we will explore the development of novel vaccines applying biotechnologies, such as vaccines based on novel administration routes, vaccines based on novel vectors, including viruses and nanoparticles, vaccines applied for cancer prevention, and therapeutic vaccines.

The annual co-circulation of two influenza A subtypes, H1N1 and H3N2, viruses in humans poses significant public health threats worldwide. However, the continuous antigenic drift and shift of influenza viruses limited the effectiveness of current seasonal influenza vaccines, necessitating the development of new vaccines against both seasonal and pandemic viruses. One potential solution to this challenge is to improve inactivated vaccines by including multiple T-cell epitopes. In this study, we designed stabilized trimeric recombinant mosaic HA proteins named HAm, which contain the most potential HA T-cell epitopes of seasonal influenza A virus. We further evaluated the antigenicity, hemagglutinin activity, and structural integrity of HAm and compared its immunogenicity and efficacy to a commercial quadrivalent inactivated influenza vaccine (QIV) in mice. Our results demonstrated that the HAm vaccine was able to induce broadly cross-reactive antibodies and T-cell responses against homologous, heterologous, and heterosubtypic influenza-naive mice. Additionally, the HAm antigens outperformed QIV vaccine antigens by eliciting protective antibodies against panels of antigenically drifted influenza vaccine strains from 2009 to 2024 and protecting against ancestral viruses’ lethal challenge. These results suggest that the HAm vaccine is a promising potential candidate for future universal seasonal and pandemic influenza vaccine development.

Authors: Horiuchi Tae , Furukawa Kyohei , Kikusato Motoi
Published: September 2024

Background: This study aimed to evaluate the suppressive effects of β-hydroxybutyrate (BHB) administration on lipopolysaccharide (LPS)-induced inflammation in broiler chickens. Methods: Twenty-day-old male broiler chickens were randomly allocated to three groups, each of which was treated with saline (control), intraperitoneal administration of LPS [1.5 mg/kg body weight (BW), Escherichia coli O127:B8], or LPS plus BHB (3 mmol/kg BW). Results: Plasma albumin and total protein concentration were significantly reduced by LPS administration, while BHB co-treatment partially attenuated the effects. The LPS treatment significantly induced plasma aspartate and alanine aminotransferase activities, and interleukin (IL)-6 concentration, with the increases suppressed by BHB co-treatment (p < 0.05). The LPS treatment significantly increased the gene expression levels of IL-1β, IL-6, and IL-18 in the spleen and peripheral blood monocytes (PBMC), while the increases were partially attenuated by BHB in the spleen. Relatively higher levels of BHB dehydrogenase 1 and succinyl-CoA:3-ketoacid CoA transferase were observed in the spleen and skeletal muscle, while these gene levels were lower in PBMC and the liver. Conclusions: The present results suggest that BHB can suppress LPS-induced inflammation, in which ketolytic enzyme expression levels may be involved in broiler chickens.

Objective:
We aim to develop a dual-functional bone regeneration scaffold (Q
x
-D) with antibacterial and osteogenic properties for infected bone defect treatment.
Impact Statement:
This study provides insights into antibacterial components that could be combined with naturally derived materials through a facile Schiff base reaction, offering a potential strategy to enhance antibacterial properties.
Introduction:
Naturally derived decalcified bone matrix (DBM) has been reported to be porous and biodegradable. DBM can induce various cell differentiations and participate in immune regulation, making it an ideal bone regeneration scaffold for bone defects. However, DBM does not exhibit antimicrobial properties. Therefore, it is essential to develop antibacterial functionalization method for DBM.
Methods:
DBM was modified with a macromolecular quaternary ammonium salt (QPEI). A series of Q
x
-D with tunable feeding ratios were synthesized through Schiff base reaction. The morphology, chemical property, in vitro antibacterial efficiency, in vitro biocompatibility, osteogenic property, and in vivo anti-infection performances were characterized.
Results:
All Q
x
-D exhibited marked antibacterial properties. Small adjustments in feed concentration could not induce changes in antibacterial properties. However, cell viability slightly decreased with increasing feed concentration. Q10-D demonstrated significant antibacterial properties and could promote recovery of infected bone defect in an animal model.
Conclusion:
Q
x
-D shows marked antibacterial properties and good biocompatibility. Moreover, Q10-D could be a potential choice for infected bone defects.

The Effect of Self-Citation on Scholarly Recognition and Visibility
Authors: Aljarah Ibrahim
Published: September 2024

Self-citation, an important aspect of academic work [1], requires careful oversight to protect the integrity and perception of scholarly contributions. Although self-referencing is often necessary for expanding upon past research, an excessive amount can negatively affect a researcher's reputation and rankings in academic indices. Indices/Lists like the Highly Cited Researcher (HCR) [2] index by Clarivate Analytics often adjust or exclude metrics associated with high self-citation rates to provide a more accurate representation of a researcher's impact, thereby enhancing visibility and credibility. According to the authors of [3] [4], self-citation rates typically range from 7.38% in Economics & Business to 15.6% in Mathematics. The same authors in [3] recommend keeping self-citations below 10%, which aligns with the general agreement among academic institutions and researchers. Maintaining this limit helps in qualifying for prestigious rankings and awards, promoting fair competition in academia. There are several methods to verify the self-citation ratio, with two of the most popular ones being the use of the Scopus platform [5] and the Web of Science (WOS) portal by Clarivate [6]. Scopus and WOS do not directly display the self-citation rate, but they do offer both the total citation count and the count excluding self-citations. Additionally, these portals can generate a citation report for authors, providing details on the number of citations, h-index, citing articles (with an option to exclude self-citations), and a year-by-year breakdown of citation counts. To find the self-citation rate Scopus and WOS, subtract the number of citations excluding self-citations from the total citations, divide this result by the total number of citations, and then multiply by 100 to get the percentage. For instance, if the total citations are 12,526 and the citations excluding self-citations are 12,000, the difference of 526 self-citations divided by the total results in a rate of 4.199%. This percentage indicates how much self-citations add to the overall citation count, which is important for maintaining appropriate citation standards.

The Influence of Concept Map Method on Student Learning Outcomes at MA NW Kotaraja
Abstract
This study aims to analyze the influence of the concept map method on student learning outcomes in physics at MA NW Kotaraja. The research employed an experimental design with two groups: an experimental group that received instruction using the concept map method and a control group that received conventional teaching methods. The sample consisted of 56 tenth-grade students, divided into two groups: 31 students in the experimental group and 25 in the control group. The results showed that the average post-test score for students in the experimental group was 75 with a standard deviation of 10, while the control group averaged 57 with a standard deviation of 9. Hypothesis testing revealed that the t-value of 7.148 exceeded the critical value of 1.671 at a 95% confidence level, indicating a significant difference between the two groups. These findings suggest that the concept map method significantly enhances student learning outcomes compared to conventional methods. Recommendations for future research include the application of concept maps in other subjects and the integration of technology in teaching.

Hal ini menunjukkan bahwa pengendalian suhu pelapisan sangat penting untuk mengoptimalkan sifat estetika dan mekanik dari logam yang dilapisi. Temuan ini sangat relevan bagi industri seperti otomotif dan dirgantara, di mana peningkatan performa mekanik dan kualitas permukaan sangat penting. Penelitian ini berkontribusi pada pemahaman yang lebih baik tentang peran suhu dalam proses elektroplating dan memberikan wawasan praktis untuk meningkatkan kualitas produk melalui optimasi suhu.
Analysis of Impact Test on Decorative Chrome Electroplating Using Copper Base Metal with Temperature Variations
Abstract
This study investigates the effect of temperature variations during the decorative chrome electroplating process on the impact strength and brightness of copper-based metal. Electroplating was conducted at three different temperatures: 50°C, 60°C, and 70°C. The results indicated that higher electroplating temperatures lead to increased brightness and impact strength of the coated copper samples. Specifically, the impact strength increased progressively from 1.8371 joules/mm² at 50°C to 1.9259 joules/mm² at 70°C. This suggests that controlling the plating temperature is crucial for optimizing both the aesthetic and mechanical properties of electroplated metals. These findings are particularly relevant for industries such as automotive and aerospace, where enhanced mechanical performance and surface quality are critical. The study contributes to a better understanding of the role of temperature in the electroplating process and provides practical insights for improving product quality through temperature optimization.

Orality in Song and the Advancement of Traditional History: The Experiences of Saidu Faru
Authors: Aminu, PhD Taofiki , Ibrahim Mal. Ahmed
Published: September 2024

Since antiquity, orality has been the only genre through which thoughts and ideas are commuted and disseminated by heart, either as songs or traditional historical antecedents to the nascent and generation unborn. It is usually in the form of traditional history by which information is collected, commuted and disseminated in song form through the mouth. Albeit, songs of variegated types have tremendously been instrumental to a plethora of transformations evident in all human global societies. This is a similitude of the invaluable multivariate songs sung by Mal. Saidu Faru- an African iconic song composer from Faru village in Talata Mafara in the present Zamfara State, Nigeria. Historically, some of his songs to some extent have indelibly contributed positively to the remoulding and repositioning of human life, psyche, and characters, and especially in strengthening, the governance, religion (Islam), cultural heritage and political advancement of northern Nigeria society. The nature of philosophical songs soothes the human mind, bringing solace and redirection of hopes through religious proclivity that has culminated in the serene ambience that makes Mal. Saidu Faru songs were indispensable. Based on the foregoing prism, the paper adopted the historical paradigm of data collection (primary and secondary sources) and equally used qualitative content analysis for interpretation. The paper recommended that Mal. Saidu Faru songs should be listened to, especially to derive the invaluable benefits in remoulding human character, repositioning societal malaises toward the creation of peace, and harmonious relations, as quintessential to good governance in Nigerian society.
