Introduction. The relevance of the study is due to the need to assess the real expansion of West Nile fever (WNF) in Russia, analyze the manifestations of epizootic and epidemic processes and study the population structure of West Nile virus (WNV).
Aim. To obtain objective data on the intensity of WNV circulation in certain territories of Russia and study the properties of the isolated strains of the pathogen.
Materials and methods. 4564 samples of field material from 23 subjects of the Russian Federation and 1547 samples of clinical material from 12 subjects of the Russian Federation were examined. A set of laboratory diagnostic methods was used: ELISA, RT-PCR, virological, sequencing.
Results. In 20 out of 1331 (1.5%) examined febrile patients, IgM antibodies to WNV were detected, including positive cases identified for the first time in the Karachay-Cherkess Republic, Tver and Vladimir regions. The presence of immunity to WNV was found on average in 8.6% of 11 federal subjects' population with high seroprevalence rates in Zaporozhye (24,5%), Tula (15,4%) and Kursk (11,1%) regions. Low-avidity IgG antibodies were detected in 44 (33,1%) samples from a population of 9 federal subjects. Intensive circulation of WNV lineage 2 in the epizootic cycle in the southern part of European Russia was confirmed. 12 WNV isolates were obtained, including those isolated for the first time in the Republic of Crimea, the Karachay-Cherkess Republic and the Stavropol Territory. The heterogeneity of circulating WNF causative agent's strains related to the two clades of the WNV lineage 2 formed in 2021 and 2022 was established.
Conclusion. In the course of comprehensive monitoring studies, a new northern border of the WNF range was established, which as of 2022 passes through the territory of the Tver region. Data from seroepidemiological studies, including the detection of low-avidity IgG antibodies, confirm fairly intense, but undiagnosed contact of the population of the European part of Russia with the WNF pathogen. In the southern region of the European part of Russia, WNV genotype 2 predominantly circulates, belonging to at least two clades formed in 2021 and 2022.

Objective: to investigate the regional peculiarities of Streptococcus pneumoniae carriage in the pediatric population and characterize the dominant serotypes of the pathogen.
Materials and methods. The clinical study group consisted of 509 healthy children attending preschool institutions. Examination of nasopharyngeal samples for the detection of S. pneumonae was carried out by classical bacteriological and molecular biological methods. The serotype was determined by real-time PCR. Genome-wide sequencing of the serogroups 15 and 11 isolates and bioinformatic analysis were performed.
Results. The S. pneumoniae bacterial carriers in the group of healthy children was detected in 207 children (40.7%), while the frequency of detection of S. pneumoniae in urban children living in Kazan was significantly higher than in children living in rural area and amounted to 53.4 and 31.1%, respectively (p 0.05). Among children vaccinated with the 13-valent pneumococcal conjugate vaccine (PCV-13), S. pneumoniae carriers were not detected in 57.5% of cases. There were no significant differences in the degree of nasopharyngeal contamination depending on the vaccination status. Analysis of the serotype composition indicates the predominance of vaccine serotypes (57.7%), while the share of serotypes included in the PСV-13 vaccine accounts for only 24.7%, the share of non-vaccine serotypes was 32.1%, untyped — 10.2%. In unvaccinated children, vaccine serotypes that are part of the PCV-13 and 23-valent polysaccharide pneumococcal vaccine prevailed (PPSV-23): 6ABCD (21%), 11 AD (15%), 14 (13%). In vaccinated children, serotypes not included in the active vaccines dominated: 15AF (17.4%), 23A (19.2%), as well as 11AD (19.6%) (11А is included in PPSV-23). The 27 Kz isolate (serotype 15C) belonged to one of the most common sequence types ST1025. The 105_Kz isolate (serotype 11D) belonged to another common sequence type ST 62.
Conclusion. In order to improve epidemiological surveillance of pneumococcal infection, it is necessary to introduce the monitoring of circulating clonal complexes of dominant S. pneumoniae serogroups and analyze the genetic determinants of antibiotic resistance and virulence depending on the sequence type.

Humans create an estimated 6.4 trillion litres of pee annually, which is often considered to be waste even though it has the potential to be a large source of liquid fertilizer, power, and other resources that may be used to grow the economy. This article addresses physicochemical properties, energetic value, hydrogen production methodology, socioeconomic uses, and sustainable energy sources for household use that might aid in the urea's conversion into hydrogen molecules at low-cost energy generation. The results of the laboratory examination of the examined urine showed 0.01% magnesium, 0.01% calcium, 0.03% uric acid, 0.04% ammonia, 0.1% sodium, 0.11% creatinine, 0.11% phosphate, 0.16% sulphate, 0.5% potassium, 0.61% chlorine, and 1.82% urea. Urea represents 52% of urine constituents with the highest concentration (1.82%), making it a significant source of clean fuel and the main producer of hydrogen gas. 1.08 g of hydrogen gas was produced from 15 litres of used urinals, and the amounts were 78.9 g, 146.2 g, 218 g, 289 g, and 343.5 g, respectively. In the same amount of time, a generator powered by gasoline consumes more fuel than one powered by hydrogen. Hydrogen burns more effectively than gasoline, using 33KW energy consumption compared to 33.5 MJ for the same amount of 1 kg of gasoline. When used as a generator fuel, Hydrogen is around 15% more efficient than gasoline. Hydrogen is a fully clean source of energy for both the industrial and home markets because its combustion yields solely water vapour.

Authors: Kareem Sarah Jamal
Published: March 2024

Background: Early childhood caries is a biofilm-dependent, critical, widespread health problem in both developing and industrialized countries. The interleukin-6 (IL-6) has several roles in the body's response to inflammation and tissue damage. TNF-α is a pleiotropic cytokine that acts as a pro-inflammatory cytokine. Aim of Study: The purpose of this research was to assess the salivary concentrations of TNF-α and IL-6 in children with dental caries and study the correlation between cytokines and DMFs index. Materials and Methods: Eighty children aged four and five took part in the study. Forty children with ECC served as the research group, whereas 40 caries-free children of the same age and gender served as the control group. Clinical parameters were assessed after an oral examination and measurement. All participants had saliva samples obtained. IL-6 and TNF-α concentrations in saliva were estimated using an ELISA test. Results: The current study found a significant elevation (P<0.05) in mean levels of TNF-α and IL-6 among children with ECC in comparison to caries free children. Moreover, there is significant positive correlation between IL-6 and TNF-α levels in caries children. Conclusion: Based on these results, it seems likely that elevated levels of TNF-α and IL-6 are involved in ECC.

A Síndrome do Desconforto Respiratório Agudo (SDRA) resulta de insuficiência pulmonar devido à ventilação alveolar primária e é exacerbada por uma série de fatores de risco, particularmente aqueles que afetam bebês pequenos (BPN). Revisar as evidências clínicas disponíveis sobre o manejo da síndrome do desconforto respiratório agudo em bebês gravemente enfermos para fornecer recomendações clínicas baseadas em evidências e na experiência para o manejo de pacientes com SDRA. Este estudo é uma revisão da Base de Dados de Enfermagem para o Manejo da Síndrome do Desconforto Respiratório Agudo em Bebês Prematuros (BDENF), Scientific Electronic Library Online (SCIELO), PubMed e Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS). O objetivo do manejo moderno da SDRA é aumentar a sobrevivência dos recém-nascidos por meio de métodos e diretrizes e reduzir as complicações da SDRA. As diretrizes dos EUA e da Europa recomendam a aplicação precoce de ventilação não invasiva (VNI) para tratar dificuldades respiratórias em bebês prematuros para melhorar os resultados. O suporte respiratório contínuo é um dos pilares do tratamento da SDRA em recém-nascidos, e vale ressaltar que a administração de surfactantes exógenos contribuiu para a sobrevivência desses lactentes. Em resumo, questões importantes precisam ser abordadas para melhorar o manejo e os resultados da SDRA em bebês prematuros. A terapia com surfactante desempenha um papel importante no tratamento da SDRA porque melhora a sobrevida e reduz o pneumotórax.

O uso de sais metálicos no tratamento de água e efluentes apresentarem baixo custo e grande eficiência na remoção de particulados. Porém, a possível presença remanescente de íons metálicos pode comprometer a saúde humana e o ecossistema. Assim, os coagulantes naturais derivados de taninos surgem como uma alternativa sustentável ao propor a formação de lodo biodegradável, de menor volume e fácil disposição no meio ambiente. Objetivou-se avaliar a eficiência do coagulante natural Acácia Negra nas etapas de coagulação, floculação e decantação do tratamento de efluente doméstico. Em laboratório, o efluente foi submetido aos ensaios no equipamento Jar Test, onde foram adicionadas seis diferentes concentrações de sulfato de alumínio e acácia negra (40, 80, 120, 160, 200 e 240 mg.L-1), com três repetições cada experimento. A eficiência de tratamento foi medida por meio de análises físico-químicas das amostras tratadas sob os parâmetros de cor, condutividade, turbidez, sólidos sedimentáveis, pH e alcalinidade parcial e total. Os testes revelaram que nas concentrações de 40 e 80 mg.L-1, as amostras tratadas com Acácia Negra apresentaram maior eficiência na remoção de turbidez e cor, redução no volume de sólidos sedimentáveis e a preservação da alcalinidade da massa líquida quando comparados com o sulfato de alumínio.

Los objetivos centrales de la indagatoria fueron analizar la asociación entre el estrés académico y el autoconcepto, comparar dichos fenómenos psicológicos entre géneros e identificar el poder predictivo de los factores del autoconcepto en los índices de estrés académico en estudiantes universitarios. Los resultados confirmaron una asociación negativa entre las variables abordadas y diferencias hombres y mujeres. Adicionalmente, se realizaron dos análisis de regresión lineal múltiple para cado uno de los géneros. En mujeres, los factores emocional, académico-laboral, social, familiar y físico del autoconcepto aportaron a la explicación del estrés académico; en el de los hombres, solo se integraron las dimensiones emocional y académico-laboral. Se concluye que el autoconcepto aporta a la predicción del comportamiento del estrés académico en estudiantes de educación superior. Por tales razones, resulta conveniente suscitar en las instituciones universitarias, actividades tendientes a la mejora de la percepción de sí mismos por parte de los jóvenes.

The study aimed to compare the knowledge, attitudes, and practices of doctors and medical students about stethoscope hygiene and investigate the microbial load and prevalence of MRSA on stethoscopes. This cross-sectional, experimental study surveyed 100 participants, including 50 doctors and 50 medical students, and used microbiological tests to determine the microbial load and presence of MRSA on the stethoscopes. The results showed that medical students had a significantly higher median bacterial load than doctors, and 8 stethoscopes were contaminated with MRSA. All participants had excellent knowledge of nosocomial pathogen spread and the role of stethoscopes in transmission. However, only half acknowledged cleaning their stethoscopes after each patient; time constraints, complacency over time, and too many patients were common reasons for not cleaning frequently. The study suggests that hospital management and quality specialists should introduce rigorous quality assurance and infection control training.

Zingiber zerumbet (L.) Roscoe ex Sm. is a herbaceous medicinal plant from the Zingiberaceae family. Previous studies have mainly focused on the essential oils of the plant with little attention to its secondary metabolites. LCMS-Orbitrap is used to analyze ethanolic extract of Z. zerumbet rhizome. Dereplication is a technique applied to identify chemical constituents based on their accurate mass and comparison with custom databases, Dictionary of Natural Products (DNP), and literature using an operating system named MZmine 2.53. In this study, we have identified chemical constituents related to several classes, including flavonoids, terpenoids, diarylheptanoids, terpenes, phenolic compounds, and fatty acids. Our results provide useful information for further isolation and identification of other unknown compounds and mass spectroscopy-based metabolite profiling of Zingiber species.

This study aims to develop and obtain the validity and usability of The Isometric Trio Kit, a teaching aid (BBM) in teaching and facilitation (PdPc) for the Form Two Translation topic. The design of this study is referred to as the Design and Development Research (DDR). It only involves the first two phases, namely the Analysis Phase and the Design and Development Phase which apply to the use of the ADDIE model. The kit’s validation process is performed by five experts, namely four Mathematics lecturers in a public university and one mathematics teacher in a secondary school to evaluate the kit. Next, using the simple random sampling, 30 trainee mathematics teachers from Universiti Pendidikan Sultan Idris (UPSI) were chosen to determine the usability of the kit by completing the kit’s usability questionnaires. Feedback from experts was analyzed using the Content Validity Index (CVI), while the usability of the kit was determined through the mean score value. The analysis results showed that the CVI value for the RPH content validity, the face and kit content validity were 1.00, which is satisfactory. The analysis results also show that the developed kit has a high level of usability with a mean score of 3.71. As a conclusion, the RPH and the kit are feasible and can be referenced and used to meet the learning standards and align with the Form Two Translation topic. This study provides new ideas, guidance, and information to teachers, particularly mathematics teachers in order for them to use the teaching aid in the classroom.

This case study is on purpose to analyze the oral mode communication strategy in teaching mathematics (SKMLPM) of five form-one (T1) Dual Language Programme (DLP) class mathematics teachers, at national-type secondary schools, Kinta Utara, Ipoh, Perak. SKMLPM consists of noise-extinguisher, voice-controller, voice-equalizer, voice-mixer and voice-recorder. T1-DLP-mathematics teacher faces challenge to implement oral mathematics communication and needs a detailed guide. This study provides a guide for T1-DLP-mathematics teacher to implement oral mathematics communication, and a reflection to Secondary School Standard Curriculum planner about learning and facilitating’s situation in school from communication perspective. Data collection methods were teaching observation, interview, fieldwork’s note and document analysis. Content analysis method was used to analyze the data. The research’s findings indicate that the number of participants who had the SKMLPM’s goal, cognitive domain (five), affective domain (four), and psychomotor domain (none). Affective domain’s level is limited within receiving and giving response. Five participants implemented SKMLPM at component phase. Only two participants implemented half-voiced voice-recorder. Five participants had the common problem, time constraint and teaching aids (ABM) voice-mixing problem. Conclusion, the SKMLPM’s goals of the participants were not holistic. The participants implemented SKMLPM through enhancing the constructing sound and lessening the disturbing sound. Participants faced problem during implementing SKMLPM. The implication of this study is teachers should (i) plan holistic SKMLPM’s goals. (ii) enhance SKMLPM component performance skills. (iii) plan time management and ABM selection. Future study is required to study the effectiveness of SKMLPM, teacher’s understanding about SKMLPM’s goals, the relation between voice-level practice and student’s ability to control voice-level, and teacher’s perspective towards the implementation of half-voiced voice-recorder.

Published: March 2024

There is a need for a collective consideration among experts in special education to reach a mutual agreement when constructing an instrument to find a solution as expected. This study collected the perspectives of 10 special education experts to determine the elements for the Learning Styles-Based Mathematics Intervention Instrument for Students with Learning Disabilities (IMGaP) using the Fuzzy Delphi Analysis. The first round of FDM involved interviews with six experts to obtain extensive data based on the themes and sub-themes identified. The instrument determination table was constructed as a guideline to develop the IMGaP Fuzzy Delphi survey form. In the second round of the Fuzzy Delphi Method (FDM) study, the themes and sub-themes identified were used to develop the items in the IMGaP instrument survey. The IMGaP instrument was designed as a questionnaire with a 7-point Likert scale. There are 79 items from four dimensions. The findings showed all expert panels reached >75%, agreement and consensus, the threshold value of d≤0.2, and defuzzification (Amax) of >0.5, as prescribed. In this regard, the Fuzzy Delphi Method successfully interpreted the decisions made by expert panels based on priorities as guidelines and best practices. It has proved that the IMGaP implementation mechanism could determine the importance of considering learning styles as an important factor when conducting mathematics interventions for students with learning disabilities.

Mentha pulegium, a species of Lamiaceae family, is flowering plant native to Europe, North Africa and the Middle East. Crushed M. pulegium leaves exhibit a very strong fragrance like spearmint. The objective of the study was to investigate the phytochemical constituents and antibacterial activity of M. pulegium stems and leaves vacuum liquid chromatography (VLC) fractions. The powdered leaves and stems were macerated with absolute methanol then filtered using Buchner system. The filtrate was evaporated, then submitted to VLC using different solvents, and their fractions were collected. Phytochemical screening tests were done to investigate the chemical composition of methanol extract. The antibacterial effect of both methanol crude and the five extracts was studied on gram positive (S. aureus and S. haemolyticus) and gram negative (P. aeruginosa and K. pneumoniae) bacteria using minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC). The results indicate the presence of flavonoids, saponins, tannins in plant aerial parts with the presence of alkaloids but in a lesser degree. The result of antibacterial assay showed that MICs of methanol fraction were approximately 900 µg/ml for gram positive bacteria (S. aureus and S. haemolyticus), 225 µg/mL for P. aeruginosa and 450 µg/mL for K. pneumonia. While the best MBCs of the five fractions along with MOHM extract gave, the bactericidal effect in concentrations 450 μg/mL for P. aeruginosa. Our study is the first report on phytochemical screening and antibacterial activity of VLC fractions of Mentha pulegium.
