Authors: Nyamtsu E. , Klechkovskyi Yu.
Published: February 2025

Goal. To determine the mebrocarbon mixtures with minimum consumption rates of methyl bromide effective against the Guatemalan potato moth (Tecia solanivora Povolny) and to develop fumigation regimes for the protection of fresh potato tubers from this pest.
Methods. Bibliographic and analytical, laboratory, mathematical and statistical methods, as well as the method of analogous modeling were used in the research.
Results. The technical effectiveness of mebrocarbon mixtures against potato moth was determined by the experimental method. Ten mixtures of methyl bromide with carbon dioxide and the standard were studied at a temperature of 4—8°C in four replicates, namely, five at a carbon dioxide temperature of 0°C when introduced into the fumigation space of the chamber and five at a temperature of 25°C. Technical methyl bromide was used as a standard. The standard consumption rate was 60 g/m3. The standard was introduced into the fumigation space of the chamber at a temperature of 25°C. The consumption rates of technical methyl bromide in the mixtures were gradually reduced by 30%, 40%, 50%, 60% and 70%, i.e., they were 42 g/m3, 36 g/m3, 30 g/m3, 24 g/m3 and 18 g/m3. For CO2, the consumption rate in the mixtures was 160 g/m3. The exposure time corresponded to 5 hours. After the treatment of fresh potato tubers with methyl bromide dosages of 42 g/m3, 36 g/m3, 30 g/ m3, provided that CO2 at a temperature of 0°C was introduced into the fumigation space, no live insects were found in the biotests, i.e. the technical efficiency was 100.00%. In tubers with biotests treated with mixtures with methyl bromide dosages reduced by 60% and 70% (24 g/m3 and 18 g/m3), an average of 1.5 and 5 live insects were found, respectively. At the same time, the technical efficiency was 98.50 and 95.00%, respectively. In the case when carbon dioxide was introduced into the fumigation space at a temperature of 25°C, no live insects were found in the biotests of the first four mebrocarbon mixtures, i.e., the technical efficiency was 100.00%. In the biotests of tubers treated with a mixture with a 70% reduction in CH3Br, i.e., with a consumption rate of 18 g/m3, two live insects were found. The technical efficiency was 98.00%.
Conclusions. Taking into account the results of the research, it is advisable to use mebrocarbon mixtures in the fumigation of imported fresh potato tubers against the quarantine pest Tecia solanivora Pov. At the same time, there is a 2.5-fold reduction in the load of methyl bromide on the environment with 100% treatment efficiency and the absence of its phytotoxic effect on the treated plant products.

Authors: Panchenko T. , Chervyakova L. , Tsurkan O.
Published: February 2025

Goal. Development of the method of analytical determination of the mixture of phosphoric acid and aluminum phosphite in the fruits of stone and grain crops by the photometric method.
Method. The mixture of active substances was determined by the photometric method. The linear range of dependence of the optical density of solutions of the derivative on the mass concentration of active substances was estimated by a mathematical and statistical method.
Results. The determination of inorganic compounds includes the same steps as the determination of organic compounds: sampling and storage of samples, extraction of the pesticide from the sample, purification of the extract from co-extractive compounds and concentration, identification and quantification by an appropriate method. Taking into account that aluminum phosphite and phosphoric acid are polar compounds (according to the extraction method), the mixture of the active substances under study is extracted with a solution of mineral acid with an appropriate dielectric constant. Identification of the phosphite mixture is carried out after performing a qualitative reaction of phosphorus-molybdenum derivative formation. The quantitative determination of the mixture of phosphoric acid and aluminum phosphite in the sample is determined by the calibration dependence of the optical density of the resulting solution of phosphorus-molybdenum derivative (D) on the mass concentration of phosphites in the extract (C, μg/ml). This dependence is linear in the concentration range of 0.25—0.50 μg/ml and is described by the regression equation D = 0.0450 × С + 0.0091.
Conclusion. The developed method for determining the mixture of phosphoric acid and aluminum phosphite provides for the determination of the mass fraction of active substances in stone fruit and pome fruits in the concentration range from 0.10 mg/kg to 2.00 mg/kg with high accuracy (2.7—6.6%) and reproducibility and can be used to control the quality of fruit products at the level of hygienic standards.

Authors: Safronova T.
Published: February 2025

Goal. To study the impact of hormonal origin preparations under controlled conditions on the ontogenesis and productivity of potato varieties-differentiators in culture in vitro.
Methods. The researches conducted in biotechnological laboratory of agriculturaal crops Ukrainian science-research plant quarantine station Institute of Plant Protection NAAS. The Murasige-Skoog (MS) nutrient medium was used with adding of various concentration of growth regulators: Epin-Maxi (2.4-epibrassinolide, 0.012 g/l) and Poteytin (2.6-dimethylpyridine-1-oxide with succinic acid, 0.15 mg/l) in the presence of adenine (0.5 mg/l) in the medium during the experiment. The study was conducted on potato wart cultivar — differentiators of different ripeness groups: Glazurna — early, Chervona Ruta-medium-ripened. The plants were grown in a cultivation room at a 16-hour photoperiod with a lighting intensity of 2000—2500 Lx, a temperature of 21—25°C and an air humidity of 60—80%. Each cultivar cuttings were carried out in the amount of 25 plants, with three times repetition of the experiment.
Results. The morphogenesis were the highest in comparison with control during the input into the nutrient medium MS growth medium Epin-Maxxi (0.025 g/l) or Poteytin (0.3 mg/l). The increased ability to grow and form more internodes was recorded on 10—15% on 21 st day of cultivation. The root forming intensity was determined during the present phytohormones adding. The microtubers average number and average mass increased.
Conclusions. The researched preparations usage allowed to increase productivity cultivar-differentiators for wart potato in culture in vitro with minimal costs. Growth stimulators Epin-Maxi and Poteytin increased the morphometric indexes at plants during their input into the medium. They favored the culture growth and development. They favored the root-forming of potato plants and microtubers quantity increase. Adenine, is as a component of nucleic acids and coenzymes. It plays an important role in plant metabolism. It favors the effective energy usage and impacts on photosynthesis intensity. It causes the Adenine impact as cytoconin on potato growth, development and resistance to stress factors (drought, excessive moisture nutrient lack).

Published: February 2025

Goal. To investigate the effect of water extracts of weeds on the germination of corn seeds.
Methods. Informational and analytical, laboratory research, mathematical and statistical. Weed plants (10 g) were crushed, poured with boiling water (200 ml), infused until cooled, 1 ml of the finished solution was taken and placed in Petri dishes and corn seeds were laid out. Seed germination was recorded after 3—4 days. The effect of aqueous extracts of 17 types of weeds was investigated.
Results. Weed plants showed both inhibitory and stimulating effects on the germination of corn seeds. Seeds germinated intensively with 100% germination in plant extracts of Chenopodium album L., Setaria glauca L. and Galium aparine L. Other species inhibited seed germination to one degree or another. The greatest suppression was shown by the plants of Barbaréa vulgáris R. Br., Polygonum convolvulus L., Elymus repens (L.) Gould and Erigeron canadensis L., in the extracts of which only 65—75.0% of seeds. A slight inhibitory effect on the germination of corn seeds was also exerted by sorghum, birch mustard, common flatleaf, and yellow thistle with a germination rate of 80%, 83% and 85%. In the extracts of such plants as Ambrosia artemisiifolia L., Convolvulus arvensis L., Taraxacum officinale Wigg., Portulaca oleracea L., Equisetum arvense L. maize seed germination had a depressed appearance, with small stems without root formation, indicating an indirect effect of these plants on maize seed germination.
Conclusions. Water-soluble secretions from weed plants showed a direct inhibitory, mediated, or stimulating effect on the germination of corn seeds. Chenopodium album L., Setaria glauca L. and Galium aparine L. had no negative effect on corn seed germination. However, most weeds inhibited seed germination. The greatest suppression was shown by the extracts of Barbaréa vulgáris R. Br., Polygonum convolvulus L. and Erigeron canadensis L.
Assessment of the influence of weather conditions and the protection system on the development of harmful organisms in the Western Forest zone
Authors: Snizhok O. , Pershuta V.
Published: February 2025

Goal. To study the influence of weather conditions and protection system on the species composition of pests on sunflower crops in the Western Polissya region.
Methods. Visual — to determine the phenological phases of growth and development of the crop; counting — to determine the development of diseases, pests, parameters of the crop structure and crop yield; chemical — to determine the content of nutrients in the soil; mathematical and statistical — to assess the reliability of the research results.
Results. It was found that in the sunflower agrocenosis, weather conditions and the protection system have a significant impact on the species composition of pests in the Western Polissya region. It was found that climate change (the average annual air temperature in Ukraine has increased by more than 0.9°C over the past century) and the creation of new early-ripening sunflower varieties and hybrids have led to favorable conditions for growing the crop in the Western regions. The analysis of statistical data showed that the area under sunflower in Rivne region increased from 3 thou hectares in 2015 to 49 thou hectares in 2023, and in Volyn region — from 2 to 41.8 thou hectares. However, these regions are subject to fluctuating weather conditions, with heavy short-term rains alternating with drought. Violations of agricultural practices also contribute to the problem. These factors lead to an increase in pathogenic infections and the number of weeds. Studies have shown that the species composition and development of diseases and weeds are directly dependent on weather conditions. In 2022, the average daily air temperature was 11.1°C, which is 2.0°C lower than long-term data, and there was 49.6 mm of precipitation (the climatic norm is 24 mm). Such weather conditions significantly slowed down the development of sunflower and contributed to a high density of weeds (816.0 plants/m2). In 2021 and 2023, the number of weeds did not exceed 487 units/m2. During the growing season, the optimum air temperature (19.8°C) and frequent precipitation (283.8 mm of precipitation) in 2022 caused a significant development of septoria (30.2—32.4%) and white rot on sunflower stems (28.0—35.0%) in variants without fungicides, and the development on baskets was 59.0—65.0%.
Conclusions. In the Western Polissya zone, the most common weeds during (2021—2023) were common spurge (Echinochloa crus-galli L.), wild violet (Viola arvensis Murr.), common bindweed (Amaranthus retroflexus L.), white quinoa (Chenopodium album L.), bindweed (Polygonum convolvulus L.), pink thistle (Cirsium arvense L.), medium starthistle (Polygonum convolvulus L.), rape stubble (Brassica napus L.), common shepherd’s purse (Capsella bursa-pastoris L.); diseases — Septoria helianthi Ell. and white rot (Sclerotinia sclerotiorum Lib.).

Authors: Fron A. , Iordosopol O. , Batco M.
Published: February 2025

Goal. The study aimed primarily at monitoring the walnut fly Rhagoletis complete Cresson and other fly species damaging the walnut tree Juglans regia L.
Methods. Monitoring of the walnut fly R. completa was conducted using EC Firuț traps with food attractants and yellow Card Cue traps, placed 2.5 meters above the ground. The traps were installed at the end of May and the beginning of June, both in industrial walnut orchards and isolated walnut stands in urban areas.
Results. Harvesting of damaged fruits began in mid-August, and the analysis involved removing the endocarp and examining the kernel to count the ontogenetic stages of pest species. During, the spring-summer period, no walnut flies were found in the traps, but a few specimens of Rhagolethis cerasi were observed. By the end of summer, two species of flies were identified. The first species, Polyodaspis ruficornis, the second species, Odinia meijerei. They can be taxonomically differentiated by pupae and adults.
Conclusions. Monitoring with food pheromones did not indicate the presence of R. completa in the central region of Moldova, but characteristic damage of this species was observed. Fruit analysis showed that the damage was caused by the cereal fly P. ruficornis. Maximally, up to 97 pupae and larvae were found in a single fruit. In the stations, an average number of 0.01 to 18.4 per 50 analyzed fruits was recorded, which constituted 68% of affected fruits. Additionally, parasitism of the pupae by more than two species of parasites and from the Pteromalidae, Eulophidae families was observed. The results underscore the importance of ongoing monitoring and research of local pests, as well as their significant impact on walnut production in Moldova. The study highlights the need for effective pest management measures to protect walnut crops and maintain sustainable production.

Authors: Andriychuk T.
Published: February 2025

Goal. To evaluate the damage of potatoes by tracheomycoses and to identify the most common tracheomycotic diseases, to study the symptoms of diseases, to analyze and clarify their etiology.
Methods. The research was conducted during 2022—2023 at the Ukrainian Research Station of Plant Quarantine of the Institute of Plant Protection, using field (survey of potato plantations to identify and establish the spread of tracheomycotic diseases of potatoes) and laboratory (identification of pathogens) methods.
Results. Studies conducted during 2022—2023 showed that tracheomycosis is a significant disease of potatoes. The main pathogens that dominated the potato plantations were the fungi Fusarium oxysporum Schl., Verticillium albo-atrum Reinke and Berthold; Colletotrichum coccodes (Wallr.) Hughes. The first manifestations of wilting, both in 2022 and 2023, were observed in the second decade of June in the budding-flowering phase. The number of affected bushes of different varieties ranged from 11 to 25%. In the second half of the growing season, the number of affected bushes increased to 35%, each of them had several dried stems. By the end of the potato growing season, wilt damage of various etiologies had already reached 65—75%. The surveys and analysis of the selected samples showed that Fusarium wilt was the most widespread in the research area in 2022 and 2023. The disease prevalence in 2022 for different varieties was 27.2—36.7%. Verticillium wilt was less common, the number of affected bushes of the studied varieties was 10.5—22.1%. In the third decade of July, symptoms of anthracnose were detected. The disease prevalence in 2022 was 14.3—25.3%. A similar situation was observed in 2023 with the dominance of Fusarium wilt, the prevalence of which was 31.7—45.3%.
Conclusions. Changes in climatic conditions have led to a significant spread of wilt diseases (Fusarium wilt, verticillium wilt, anthracnose) of potatoes and now pose a threat to the production of quality seed and food potatoes.

Authors: Pérez-Velasco Arturo Alejandro , Álvarez-Hernández Gabriel Alejandro
Published: February 2025

El presente estudio analiza la percepción y experiencia de estudiantes de la Escuela Nacional de Antropología e Historia (ENAH) sobre la Inteligencia Artificial (IA), que ha cobrado gran relevancia en el ámbito académico actual. Se busca comprender e interpretar cómo los estudiantes conciben y experimentan esta tecnología.
La información recuperada permite afirmar que los estudiantes de la ENAH no solo tienen un amplio conocimiento sobre la IA (98%), sino que también la utilizan frecuentemente (42%) para el desarrollo de sus actividades académicas. Los estudiantes la consideran una herramienta valiosa que facilita la comunicación, el aprendizaje, la investigación y la recuperación de información.
Al mismo tiempo, la visión de los estudiantes no se limita únicamente a los aspectos prácticos de la IA en su trayectoria académica. También expresan inquietudes sobre las implicaciones éticas de su uso, destacando el potencial sesgo en los resultados, la ausencia de comprensión emocional y la posibilidad de un uso irresponsable de la herramienta.
A pesar de estas preocupaciones, los estudiantes reconocen el potencial transformador de la IA en los procesos educativos. Identifican su capacidad para agilizar el acceso a la información, fomentar la colaboración y promover un aprendizaje personalizado. No obstante, enfatizan que este potencial solo se materializará si se promueve un uso responsable y ético de la IA en el contexto académico.
El estudio subraya la necesidad de desarrollar recursos educativos que guíen a los estudiantes en la aplicación de buenas prácticas en el aula, así como la importancia de generar investigaciones que exploren el impacto de la IA en el proceso de enseñanza-aprendizaje.
Factores institucionales y subjetivos que intervienen en la reprobación en la Licenciatura en Geografía de la UAEMéx
Authors: Reyes-Torres Carlos , Carreto-Bernal Fernando
Published: February 2025

La investigación constituye una aproximación cuantitativa –cualitativa sobre la reprobación escolar, se basó en el análisis de la información estadística documentada en el historial académico de los estudiantes y de los testimonios obtenidos de los educandos a través de la encuesta y la entrevista.
El interés por indagar sobre la reprobación se vincula con la carencia en la Facultad de Geografía de estudios de carácter cuanti-cualitativos que dimensionen este fenómeno y se constituyan en un dispositivo de diagnóstico.
Teóricamente se fundamenta en la perspectiva sociológica-crítica-reflexiva sobre la reprobación (Pérez y Sacristán, 1992); que enfoca la interrelación de factores objetivos y subjetivos, también retoma la propuesta de articulación de los paradigmas representados por Durkheim y Weber planteada por Tarrés (2007).
La metodología integra factores institucionales circunscritos al ámbito académico y subjetivo que inciden en la reprobación. El propósito es comprender el sentido que los educandos atribuyen a sus vivencias, causas y motivos académicos y no académicos que propician la reprobación.
Los resultados obtenidos se sistematizaron por períodos escolares correspondientes a la estructura del plan de estudios, el diagnóstico cuantitativo nos permite advertir que la mayor incidencia de reprobación está en los primeros cuatro semestres correspondientes al núcleo básico y sustantivo, así como en los cursos talleres, en menor proporción cursos. Las materias de mayor incidencia en la reprobación son: matemáticas, geodesia, topografía, edafología, geografía de México, climatología y estadística. Los factores subjetivos se organizaron en las categorías indiferencia, desenganche y baja autoestima. Se concluye sobre el carácter integral de la reprobación.

Published: February 2025

Implication Statement
Ultrasonography has become a valuable procedural guide and diagnostic tool across many medical specialties. A 2017 descriptive cross-sectional survey at Memorial University of Newfoundland found that there was support to integrate preclinical and clinical applications of point of care ultrasound (POCUS) into the undergraduate medical anatomy curriculum. Unlike previous studies that have focused on scanning a single body system, our group utilized a station-based model that allowed medical students to scan several different body systems throughout the year. Our experience in creating the syllabus, collecting feedback, and creating multiple choice assessment questions will be useful to other educators who may wish to integrate POCUS into their curriculum.

Legitimizing design thinking: Addressing barriers to corporate adoption
Authors: Passadouro Mariana , Patrício Rui , Casaca Joaquim
Published: February 2025

The design domain has long been recognized as a source of value creation, with a recent paradigm shift in both academic and practitioner circles conceptualizing design as a comprehensive innovation management practice. Design thinking (DT) has gained prominence for fostering engagement and confidence in creative processes. However, outcomes can be influenced by various factors and conditions, making direct attribution to DT challenging. While organizational maturity can impact DT implementation, this relationship is complex and warrants further investigation. More in-depth research and appropriate methodologies are needed to assist organizations in establishing the legitimacy of DT, acknowledging that legitimacy often derives from the perceived quality of work outcomes, which is inherently subjective. Therefore, it is essential to develop more objective criteria and evaluation methods to provide a clearer and more reliable basis for assessing the success and impact of DT initiatives. This paper addresses the need for legitimacy in adopting DT as an innovation strategy, with a focus on both individual and social structural perspectives. Drawing on organizational workplace theories and employee perceptions, we developed and tested hypotheses to overcome barriers to the adoption of DT. Although based on a small sample size, our study offers valuable insights into the factors influencing DT adoption within organizations. Using a quasi-experimental approach, we examined how organizational practices, leadership, and physical spaces affect the legitimacy and widespread adoption of DT. By assessing both qualitative and quantitative indicators, we combined participant feedback with observable behaviors for a more comprehensive evaluation. Recognizing the subjectivity of legitimacy measurement, we enhanced our approach by integrating multiple data sources. This study lays the groundwork for future research, refining legitimacy assessments and investigating the long-term impact of DT adoption. We hope our findings inspire further exploration of additional variables that influence the success of DT across diverse organizational contexts.
The mind-body connection: Sleep disruptions, dream processes and their effect on psychosomatic disorders
Authors: Ghiță Leon Victor , Clichici Simona Valeria
Published: February 2025

Sleep is recognized as a crucial link between mental and physical health, bridging the unconscious and conscious realms. However, the impact of both physiological and pathological sleep on the progression of diseases with significant psychological burdens, such as psychosomatic disorders, remains insufficiently understood. Gaining a deeper understanding of this relationship would offer a more comprehensive insight into both the physiology and pathophysiology of sleep, as well as the mechanisms underlying the development and progression of psychosomatic conditions. This knowledge could also guide the development of therapeutic strategies aimed at enhancing the quality of life for patients affected by these disorders. This review aimed to investigate the relationship between sleep, sleep deprivation, and dreaming in relation to psychosomatic diseases, the dependency relationships that can be established between these factors, and the medical and psychological implications that the links found have in the assessment and treatment of patients. Using a broad PubMed database search, primary and secondary studies were analyzed to understand how scientific research on this issue has evolved over time and what are the missing elements in this interconnected relationship. The study revealed that psychosomatic illnesses are complex, multifactorial conditions, strongly influenced by both normal and pathological sleep. It also highlighted that therapeutic interventions targeting sleep pathophysiology can alleviate patients’ symptoms. In addition, the theoretical insights gained from this relationship serve as an initial step toward a comprehensive understanding of the connection between the mind and body.

A study of teachers' perceptions of early childhood language and literacy education: Importance-performance analysis
Authors: Kim Soonhwan , Jang Minyoung
Published: February 2025

This study analyzes kindergarten teachers' perceptions of the importance and performance in early childhood language and literacy education in hopes of identifying practical ways to support early childhood language and literacy development. The research questions were as follows. First, how do kindergarten teachers’ perceptions of the importance differ from their perceptions of performance in early childhood language and literacy education? Second, what does an IPA analysis reveal about kindergarten teachers’ importance- and performance-related perceptions of specific areas of early childhood language and literacy? Analyzing a sample of 200 kindergarten and daycare teachers responsible for classes of 3-, 4-, and 5-year-olds, we examined differences in importance- and performance-related perceptions regarding early childhood language and literacy education. Our analysis focused on four areas (listening, speaking, reading, writing) in 22 sub-items. The results revealed similarities and differences between kindergarten teachers’ importance- and performance-related perceptions of listening, speaking, reading, and writing. The IPA analysis showed that Quadrant 1 had a high proportion of listening, speaking, and reading, mainly featuring elements related to attitude and comprehension, while Quadrant 3 had a high proportion of writing, mainly featuring elements related to the technical aspects of language, such as phonemes, fluency, and accuracy. Exploring the extent to which teachers' perceptions of the importance of each area of early childhood language and literacy education are connected to practice, the results of this study highlight the need for specific support and education in areas where discrepancies exist between perceptions and implementation.
South Korean early childhood educators’ perceptions of North Korean defectors and unification education
Authors: Seo Jiah
Published: February 2025

This study investigates South Korean early childhood educators’ perceptions of North Korean defectors, their national identity, reunification, and unification education (UE) to provide some suggestions for an effective integrated education between the children of the two Koreas and related teacher education. Fourteen educators participated in this research in which qualitative semi-structured interviews were employed. Key findings included that most educators regarded North Koreans as the ‘Same Korean race’, with the exception of young educators in their 20s, whose view was that North Koreans are not a member of the Korean people. In addition, the participants felt there were ideological, cultural, language, and economic differences between them and North Korean defectors and their children. Some participants argued that UE for young children is not inherently ineffective due to a lack of understanding of the concept of unification. Alternately, some educators addressed North and South Korean UE through multicultural educational approaches. Recommendations are made for the application of UE via multicultural education approaches at government level, in the class and teacher training.
‘We can make a difference’: School leaders’ claims about School-Age Educare in areas with socioeconomic challenges
Authors: Wernholm Marina , Ackesjö Helena
Published: February 2025

The aim of this study is to explore how School-Age Educare Centers (SAEC) adapt to the circumstances and needs of pupils living in areas with socioeconomic challenges, and how SAEC can contribute to promote pupils’ continued learning and knowledge development for further education and for life. The Swedish school-age educare offers education and care for children aged 6-12 years old, before and after school. The following research question guides the study: What claims are made about the SAEC contribution to pupils in terms of subjectification and qualification? Data consist of 13 interviews with school leaders working in schools in vulnerable areas, neighborhoods at risk, and particularly exposed zones identified by the Swedish Police. Qualitative content analysis was applied. The study is theoretically grounded in Biesta’s concepts subjectification and qualification, which are used as aspects of education. This study contributes with nuanced descriptions of how the SAEC mission to compensate and complement is claimed to be put into practice. One conclusion is that school-age educare centers can make a difference in children’s life conditions and prerequisites for succeeding in school. Another conclusion is that school-age educare centers emerge as potential arenas for crime prevention.

This study aims to describe aspects of the character hierarchy and offer an interpretation of the basic needs for survival of the characters through a literary psychology approach which can be used as an alternative to literary studies. The data source is the Malik & Elsa novel published by PT Transmedia Distributor. The focus of his research is the hierarchy of needs of figures with the theory launched by Maslow, the theory is named Abraham Maslow's hierarchy of needs t The formulation of the problem discusses physiological needs, a sense of security, belonging and love, and self-esteem. The research method used is descriptive-qualitative. Data collection techniques are reading, analysis and corpus techniques. The results showed that (1) Malik's physiological needs were met when he won the guessing game with Elsa. (2) The safety needs needed by Malik, in financial form. The aspect of feeling secure is fulfilled by working as a porter in the market. (3) Malik needs a love connection, in the form of love and affection from the opposite sex, namely Elsa. The sense of love and belonging between the two characters is fulfilled. However, due to caste differences between the two, they could not unite. (4) The esteem needs of Malik's character continue his college education.
Combined effect of topical sulfasalazine for oral lichen planus management: a randomized clinical trial
Authors: Zakaria Mai , Mostafa Basma , El Refai Ibrahim
Published: February 2025

Aim: The present study was designed to assess the effectiveness of topical application of sulfasalazine in combination with topically applied corticosteroids versus using topical steroids alone as the standard control in management of symptomatic oral lichen planus (OLP). Methods: The trial involved 46 participants having symptomatic OLP. Subjects included were divided into two equal groups at random. Group C (control group), in this group patients were treated with topically applied corticosteroids only as the standard treatment of OLP. In Group T (test group) topical sulfasalazine was used in combination with topical corticosteroids in management of the OLP cases. The patients used the topical applications four times per day in an alternate sequence (in Group T). The treatment schedule was continuous for 4 weeks with one visit weekly as a follow-up. Oral hygiene measures were strictly applied with total elimination of plaque with calculus deposits removal as they implement inflammation intra-orally and ‎exaggerate together distribution and signs of OLP lesions. Each group underwent pain assessment and sign score recordings both before and after the used management strategies. Results: The results of all patients reported no unwanted reactions or complications using both treatment strategies. Both study groups reported a significant decrease in the pain scale and sign score recordings over time as shown within the intragroup findings. Group T experienced a significantly higher reduction in pain scale (starting at two weeks) and sign score results (starting at three weeks) as compared to Group C.
Conclusions: Based on the data presented in this study, combination of topical sulfasalazine with topical corticosteroids is an efficient treatment in management of OLP in terms of decreasing pain scale and sign score values (Clinical Trials.gov with registration number NCT06060301).
Network pharmacology and in vivo study: Unraveling the therapeutic mechanisms of Panax ginseng in potentially treating ulcerative colitis

Published: February 2025

BACKGROUND

Ulcerative colitis (UC), a chronic and challenging condition, necessitates the development of more effective treatments owing to the unsatisfactory efficacy and side effects associated with current medications. Traditional Chinese medicine (TCM), known for its multi-stage and multi-targeted approach, has a long history in treating gastrointestinal diseases and offering a promising alternative UC treatment. Panax ginseng (P. ginseng ), a commonly used remedy for UC in TCM, exemplifies this potential, although the specific components and mechanisms through which its therapeutic effects are exerted remain to be fully elucidated, highlighting the need for further research to unlock its full potential as a treatment option.

AIM

To investigate the key constituents and biological pathways through which P. ginseng exerts therapeutic effects on UC.

METHODS

Network pharmacology investigated the UC-alleviating mechanism of P. ginseng , including “active ingredient-target-disease” network analysis, and Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses. Panaxadiol (PD; active ingredient of P. ginseng ) was tested in a mouse model of 3% dextran sulfate sodium-induced UC, with assessments of body weight, Disease Activity Index scores, and colon length. Colitis and intestinal barrier integrity were analyzed via hematoxylin-eosin and Alcian blue and periodic acid-Schiff staining, immunohistochemistry, real time-quantitative PCR, and western blotting.

RESULTS

By integrating and analyzing the targets of P. ginseng and UC, 15 critical hub genes were discovered. Kyoto Encyclopedia of Genes and Genomes pathway analysis revealed the mechanisms involved to be linked to MAPK and PI3K-Akt signaling. Among the 10 main active ingredients identified as potentially effective, PD was most abundant and was validated in vivo to mitigate weight loss, reduce Disease Activity Index scores, and prevent colon shortening. PD also reduced inflammation and suppressed expression of pro-inflammatory cytokines and mediators. In addition, PD increased expression of mucin and tight junction proteins. Ultimately, PD counteracted effects of dextran sulfate sodium by inhibiting phosphorylation of NF-кB and MAPK, while increasing phosphorylation of AMPK and expression of NRF2 and NQO1.

CONCLUSION

PD alleviates colitis and aids intestinal barrier repair, partly via modulation of the MAPK/NF-кB and AMPK/NRF2/NQO1 pathways. These findings also suggest new research methods for treatment of UC with TCM.

BACKGROUND

Metabolic-associated fatty liver disease (MAFLD) is characterized by lipid accumulation in hepatocytes and is closely associated with oxidative stress. Increasing clinical evidence indicates that MAFLD is linked to bone metabolic disorders, including osteoporosis. Recent studies indicate that the expression profiles of liver circular RNAs (circRNAs) are altered in MAFLD. However, the effects of these changes on bone metabolism remain poorly understood.

AIM

To investigate the effects and mechanism of differently expressed circRNAs secreted by the liver on osteogenic differentiation in MAFLD.

METHODS

RNA sequencing was performed to identify highly expressed circRNAs in the liver, validated by quantitative real-time reverse transcription polymerase chain reaction, and localized using fluorescence in situ hybridization (FISH). A mouse model induced by a high-fat diet was used to simulate MAFLD.

RESULTS

CircSOD2 was significantly upregulated in liver tissues and primary hepatocytes from subjects with MAFLD. CircSOD2 was induced by oxidative stress and attenuated by antioxidants in the mouse model. In addition, circSOD2 was delivered from hepatocytes to bone marrow mesenchymal stem cells (BMSCs). Furthermore, circSOD2 inhibited the osteogenic differentiation of BMSCs and in vivo bone formation by sponging miR-29b. Moreover, miR-29b inhibition reversed the stimulatory effect of circSOD2 silencing on osteogenic differentiation of BMSCs and in vivo bone formation. Mechanistically, the interaction between circSOD2 and miR-29b confirmed through a luciferase reporter assay and the co-localization in the cytoplasm evidenced by FISH indicated that circSOD2 acted as a sponge for miR-29b.

CONCLUSION

This study provides a novel mechanism underlying the liver-bone crosstalk, demonstrating that circSOD2 upregulation in hepatocytes, induced by oxidative stress, inhibits osteogenic differentiation of BMSCs by sponging miR-29b. These findings offer a better understanding of the relationship between MAFLD and osteoporosis.
