Genetic Diversity and Molecular Evolution of Hepatitis E Virus Within the Genus Chirohepevirus in Bats
Authors: Wang Bo , Cronin Peter , Mah Marcus G. , Yang Xing-Lou , Su Yvonne C. F.
Published: February 2025

Hepatitis E virus (HEV) is a major zoonotic pathogen causing hepatitis E, with strains identified in various animal species, including pigs, wild boar, rabbits, deer, camels, and rats. These variants are capable of crossing species barriers and infecting humans. HEV belongs to the family Hepeviridae, which has recently divided into two subfamilies: Orthohepevirinae and Parahepevirinae, and five genera: Paslahepevirus, Avihepevirus, Rocahepevirus, Chirohepevirus, and Piscihepevirus. Recent advances in high-throughput sequencing, particularly of bat viromes, have revealed numerous HEV-related viruses, raising concerns about their zoonotic potential. Bat-derived HEVs have been classified into the genus Chirohepevirus, which includes three distinct species. In this study, we analyzed 64 chirohepevirus sequences from 22 bat species across six bat families collected from nine countries. Twelve sequences represent complete or nearly complete viral genomes (>6410 nucleotides) containing the characteristic three HEV open reading frames (ORFs). These strains exhibited high sequence divergence (>25%) within their respective host genera or species. Phylogenetic analyses with maximum likelihood methods identified at least seven distinct subclades within Chirohepevirus, each potentially representing an independent species. Additionally, the close phylogenetic relationship between chirohepevirus strains and their bat hosts indicates a pattern of virus–host co-speciation. Our findings expand the known diversity within the family Hepeviridae and provide new insights into the evolution of bat-associated HEV. Continued surveillance of chirohepevirus will be essential for understanding its potential for zoonotic transmission and public health risks.

Published: February 2025

Background/Objectives: Limited research has compared tests assessing humoral and cellular immunity related to SARS-CoV-2 infection. This study evaluated immunoglobulin G for nucleocapsid (IgG(N)) and T-spot for nucleocapsid (T-spot(N)) assays against polymerase chain reaction (PCR) test results for identifying infected individuals. Methods: This study included participants who had completed five blood samplings since their second COVID-19 vaccination between 9 September 2021 and 6 November 2022. Chemiluminescent immunoassay (CLIA) tests measured the humoral immune response, IgG(S) and neutralizing activity tests the immune status, and IgG(N) tests the infection history. For cellar immunity, T-spot(S) indicated immune status, and T-spot(N) indicated infection history. Results: The primary outcome was the proportion of individuals who tested positive for PCR and the proportion who tested positive for IgG(N) and T-spot(N). Overall, this study included 2104 participants. In the PCR-negative group, 1838 individuals tested negative for IgG(N), whereas 64 tested positive at least once. The geometric mean of IgG(S) at T5 was 1541.7 AU/mL in the IgG(N)-negative group and 3965.8 AU/mL in the IgG(N)-positive group, which was 2.6 times higher. In the PCR-positive group, 25 individuals tested negative for IgG(N), while 177 tested positive at least once. The geometric mean of IgG(S) at T5 was 2700.6 AU/mL in the IgG(N)-negative group and 5400.8 AU/mL in the IgG(N)-positive group, showing higher values in the IgG(N)-positive group. Conclusions: A discrepancy was noted between PCR test results and the IgG(N) and T-spot(N) determinations. Combining multiple assays is required to accurately identify the past-infected population.

Authors: Elfeky Ahmed M. , Alfaisal Faisal M. , El-Shafei Ahmed
Published: February 2025

An alternative irrigation water supply that prioritizes quality standards, promotes sustainable water resource management, and uses ecologically friendly approaches is still being researched. The purpose of this study is to evaluate the thirteen physicochemical properties of Riyadh wastewater treatment plants (WWTPs) over eight years for their potential use in irrigation. Wastewater quality was assessed using the Comprehensive Water Pollution Index (CPI) and the Canadian Wastewater Quality Index (CWQI). Principal component analysis and heatmaps were also used to identify trustworthy parameters. The CWQI results, ranging from 72.95 to 95.55%, showed acceptable variations over eight years, indicating adequate quality. The CPI values varied from 0.19 to 0.77. However, the average CPI was determined to be 0.6, indicating that there had been some slight contamination throughout the study. The first and second components (PC1 and PC2) represented 32.6% of the data, revealing a dominant pattern for a better understanding of the effluent characteristics. The effluent parameters loaded onto PC1 were EC, Ca2++Mg2+, NO3, and COD, whereas NH4, DO, and turbidity were loaded onto PC2. The effluent from the Riyadh WWTPs is appropriate for irrigation, highlighting the necessity of TWW for agriculture and supporting Saudi Arabia’s Green Riyadh Initiative.

Published: February 2025

In this study, a millimeter-scale N/P-doped carbonaceous catalyst was synthesized via facile carbonization of the N/P-doped resin at 800 °C (NPCR-800). This work aimed to investigate the performance of the NPCR-800 catalyst in heterogeneous catalytic ozonation and the mechanism of reactive oxygen species (ROS) generation. The NPCR-800 achieved the highest oxalic acid (OA) degradation efficiency of 91% within 40 min. The first-order kinetics of OA degradation in the NPCR-800/O3 system was approximately twelve and three times higher than that in the O3 and O3/GAC system, respectively. In addition to excellent catalytic ozonation performance, the NPCR catalyst also exhibited good reusability and salt tolerance. The dominant ROS were identified by the electronic spin response and free radical quantitative experiments, being responsible for oxalic acid degradation in NPCR-800/O3 system. The effect of the doped N and P elements on enhancing the catalytic activity was understood, what was ascribed to the efficient reaction of the O3 molecule with the active site of the graphitic N, defect site and carbonyl/carboxyl groups of NPCR to generate the hydroxyl radical and singlet oxygen. A type of metal-free catalytic ozonation strategy was developed in this work, which is promising in the practical treatment of the refractory organic pollutants.

Published: February 2025

A cirurgia tem um papel essencial no tratamento da doença de Crohn, sendo indicada principalmente em casos refratários ao tratamento clínico ou quando há complicações como estenoses graves, fístulas complexas, perfurações ou hemorragias persistentes. Embora os avanços nas terapias medicamentosas tenham reduzido a necessidade de intervenções cirúrgicas, muitos pacientes ainda precisam de cirurgia ao longo da vida. As principais abordagens incluem a ressecção segmentar com anastomose primária, a estenoplastia para preservação do intestino e a proctocolectomia em casos mais severos. Com o avanço das técnicas minimamente invasivas, como a laparoscopia e a cirurgia robótica, houve uma significativa redução das complicações pós-operatórias, permitindo recuperação mais rápida e melhor qualidade de vida. No entanto, a preparação pré-operatória e o manejo pós-cirúrgico são fundamentais para o sucesso do tratamento. A otimização do estado nutricional, o controle da inflamação e o acompanhamento contínuo ajudam a prevenir a recorrência da doença e reduzem a necessidade de novas intervenções. Apesar das melhorias nas abordagens cirúrgicas, a doença de Crohn permanece um desafio, pois não há cura definitiva, e a inflamação pode reaparecer em outras regiões do trato digestivo. Dessa forma, a decisão pela cirurgia deve ser cuidadosamente planejada, levando em consideração não apenas a necessidade imediata da intervenção, mas também o impacto a longo prazo na funcionalidade intestinal e na qualidade de vida do paciente. A integração entre cirurgia, terapias medicamentosas e suporte multidisciplinar continua sendo a melhor estratégia para otimizar os desfechos e garantir um manejo eficaz da doença.
Satellite derived bathymetry as a tool for rapid assessment of storm-induced impacts to beach fill
Authors: Albada Edward , Signorin Morjana , Benedet Lindino , Ryan Chelsea , Hartmann Knut , Bödinger Christian
Published: February 2025

For state and federal beach nourishment projects, agencies often face challenges to provide rapid assessments of volume losses immediately after a storm event. These assessments play an important role in quantifying losses and assisting in the decision-making process regarding disaster declarations. Traditionally, the immediate post-storm beach assessment is conducted using visual estimates aided by limited measurements (beach elevation, scarp height, distance from dune to waterline, etc). Rapid assessments based on visual estimates and limited measurements often have a significant margin of error, especially due to the lack of data in the offshore part of the beach profile. Traditional beach profile surveys including the dry-beach and the offshore portion of the beach profile are only collected at a later date, after initial assessments and disaster declarations. Utilizing Satellite-Derived Bathymetry (SDB) to quantify the offshore portion of the profile immediately after a storm could address the issue of lack of offshore data when conducting rapid post-storm assessments for disaster declaration. SDB data is spatially complete, can be available for multiple dates pre- and post-storm (typically a few days after the storm), and it can be used to improve beach volume loss estimates of rapid post-storm assessments. However, SDB is also subject to limitations inherent in the methods and data processing which will be discussed in this paper.
The applicability of SDB is assessed here thorough comparative analysis between pre- and post- storm SDB datasets and traditional topo-bathy beach profile surveys. Both SDB data and traditional surveys were obtained at the same dates for the study area, Coquina Beach, located at the southern end of Anna Maria Island, Manatee County, Florida. By conducting this comparative analysis and examining the differences between traditional beach profile surveys and SDB data, the usefulness and limitations of using SDB in estimating preliminary volume losses after a storm event are elucidated. This analysis demonstrated that SDB data can contribute to greater accuracy in post-storm assessments to assist in initial economical loss estimate and disaster declarations as well as facilitate faster disaster response.

Authors: Yolbaş İdris
Published: February 2025

In this study, the elemental content of the endemic plant Allium pervariensis was determined using the ICP-OES method. The analysis revealed that the highest concentrations in the plant were calcium (Ca) and potassium (K), with calcium measured at 6.2278 ± 0.547 ppm and potassium at 5.5283 ± 0.482 ppm. Other elements such as sodium (Na) at 1.0325 ± 0.061 ppm, magnesium (Mg) at 0.9204 ± 0.051 ppm, and phosphorus (P) at 0.8356 ± 0.045 ppm were also quantified. Trace elements, including iron (Fe), copper (Cu), manganese (Mn), and zinc (Zn), were analyzed, while cobalt (Co) and nickel (Ni) were observed to be present at very low levels. These results indicate that the A. pervariensis plant is rich in nutrients and suggests potential health benefits. However, the study's limitation to samples from a specific geographical region necessitates caution in generalizing the results. Therefore, more extensive biochemical and clinical studies are needed in the future.

Authors: Hidayat Muhammad Nur , Yulianingsih Yulianingsih
Published: February 2025

Due to the regulation prohibiting the use of Antibiotic Growth Promoters (AGP), it is essential to explore alternative solutions for feed additives in the broiler industry. One promising approach is to utilize herbal plants as feed additives to enhance the performance and quality of broilers. This study aims to evaluate the effectiveness of herbal plant-based feed additives, specifically fermented garlic, cinnamon, and betel leaves, on the performance and quality of broiler carcasses. This study employed a completely randomized design (CRD) featuring four treatments and five replications. For a duration of 30 days, the treatments administered to the broilers included: P0 (control), P1 (herbal concoction at 1.5 ml per 500 ml of water), P2 (herbal concoction at 2.5 ml per 500 ml of water), and P3 (herbal concoction at 3.5 ml per 500 ml of water).The variables measured in this study included feed consumption, body weight gain, and feed conversion. The administration of herbal medicine did not have a significant effect (P > 0.05) on feed consumption, body weight gain, or feed conversion in broilers. However, the level of herbal medicine administration showed some trends: P3 (3.5 ml herbal medicine per 500 ml of water) was associated with better feed consumption and body weight gain, while P2 (2.5 ml herbal medicine per 500 ml of water) indicated a tendency for improved feed conversion.

The treatments in question are P0= CW-C, P1= CW-D, P2= CW-PQ, P3= CW-CD, P4= CW-CQ, and P5= CW-CDQ. Data were analyzed using one-way ANOVA and Duncan tests. Until the 6th day of storage, the P3 treatment produced higher semen quality than the control (P<0.05) except that the sperm abnormality variable showed no significant difference (P>0.05). On the other hand, treatment P3 showed no significant difference from treatments P1, P2, P4, and P5 (P>0.05). The quality of Bali cattle semen up to the sixth day of storage in treatment P3 was: 42.00%. 48.76%, 5.71%, 6.2 days respectively for the variables motility, viability, abnormalities and sperm survival. The results of this study concluded that a combination of chicken and duck egg yolks added to coconut water is the best diluent that can maintain the quality of Bali cattle sperm.

Introduction: Stunting is a serious public health problem, especially in developing countries, and can long-term impact children's physical and cognitive development. The nutritional status of pregnant women plays an important role in the growth and development of the fetus, which can affect the risk of stunting in children after birth. This study aims to analyze the influence of the nutritional status of pregnant women on the incidence of stunting in early childhood.
Research Methodology: This study uses a cohort study design involving pregnant women and their children under five years old. Data were collected through interviews, anthropometric measurements, and laboratory analysis to assess the mother's nutritional status, including macro and micronutrient intake.
Result: The analysis showed a significant relationship between the nutritional status of pregnant women and the incidence of stunting in children. Pregnant women with good nutritional status have a lower risk of giving birth to stunted children compared to pregnant women who are malnourished. In addition, factors such as maternal education, economic status, and access to health services also contribute to the incidence of stunting.
Conclusion: This study emphasizes the importance of adequate nutrition during pregnancy to prevent stunting in early childhood. Appropriate nutritional interventions and increased awareness of the importance of nutrition during pregnancy are urgently needed to improve maternal and child health. Recommendations for public health programs and nutrition policies were also discussed to address the stunting problem.

In organizing Umrah worship trips, there is a monitoring system launched by the Ministry of Religion in August 2019, namely the Umrah Integrated Management Computerization System. The purpose of this study is to determine the application of audits on the SISKOPATUH Application to evaluate and make the results as input to improve the management of this application at PT Inayah Haromain Tours & Travel. In the procedure for conducting an audit of this application carried out by researchers, it includes a process, namely: preliminary examination, further examination, examination results, discussion of examination results and recommendations / proposals, then an examination report. The results showed that there were problems that occurred in this Information System, namely the existence of a timer in the data entry system which caused the data to become more than one if the data input was long. The application of the SISKOPATUH Application Information System at PT Inayah Haromain Tours & Travel is still not efficient because there are still many resources that have not mastered this application, as well as the lack of government concern to socialize to technical personnel so that nothing detrimental to both parties occurs.

Published: February 2025

The rapid advancement of information technology, particularly in computer networking, has played a crucial role in supporting the operations of various institutions, including hospitals. RSUD Siti Fatimah is one such institution that leverages computer network technology to enhance performance and the quality of patient care. However, the hospital faces challenges with congested and slow network connections, which can hinder operational efficiency. To address this issue, a load balancing solution based on MikroTik was implemented using the Per-Connection Classifier (PCC) method, allowing the distribution of load across two ISPs for a more stable and faster connection. The PCC method was chosen for its ability to enhance connection speed and distribute network load evenly between the two gateways, thereby preventing overload. Additionally, a failover technique was applied to ensure that if one ISP connection fails, the network traffic is automatically switched to the other ISP, keeping the network operational without interruption. The implementation of this solution is expected to improve network efficiency and enhance healthcare services at RSUD Siti Fatimah.
