Nanoparticles of corn prolamine protein zein (NPQ) containing 0.005–0.26 g/g quercetin (Q) were prepared by desolvation of a 25–30 mg/mL ethanol protein solution containing the encapsulated compound with an aqueous polystyrene sulfonate. The size of zein nanoparticles and their aggregates was characterized by dynamic light scattering and atomic force microscopy; the quercetin content – by the Folin-Ciocalteu assay. While the quercetin/zein ratio in solution is less than 0.08 g/g, the polyphenol is quantitatively included in the nanoparticles, and their hydrodynamic diameter is 60–75 nm. As the quercetin/zein ratio rises to 0.20 g/g, the average particle diameter increases to 150 nm. In concentrated dispersions, aggregates with a diameter of 500–600 nm are formed. The kinetics of quercetin release from NPQ with different mass fractions of Q in distilled water and solutions simulating the environment of the stomach and intestines at 37 °C were studied.Zein nanoparticles exhibit weak activity in the reaction with ABTS cation-radicals. Quercetin encapsulated in the zein matrix generally retains the antiradical activity characteristic of the free flavonoid, however, the rate of decolorization of ABTS cation-radicals decreases due to the prolonged release of quercetin from NPQ. The cytoprotective properties of quercetin in zein nanoparticles are significantly reduced and manifest themselves only in partial preservation of the integrity of cell membranes and a decrease in the release of lactate dehydrogenase from UV-C irradiated HaCaT cells. In contrast to free quercetin, the introduction of Q in zein nanoparticles or their submicron aggregates increases the number of metabolically dead UV-C-irradiated HaCaT cells, enhancing the cytotoxic effect of UV radiation. Empty zein aggregates of submicron size have a similar effect.
Features of electrolyte coagulation of modified polyamide resin and its effect on the properties of paper and cardboard
Authors: Borkina Ya. V. , Fleisher V. L. 
Published: November 2024

The article is devoted to the study of the features of coagulation of a modified polyamide resin for paper and cardboard in the presence of aluminum polyoxychloride. It has been established that the resin under study, the component composition of which is represented by modified polyaminoamides, free resin acid, sodium resinates and maleopimarate, is resistant to water hardness salts, however, the sodium resinates present in its composition are subject to hydrolysis. The process of coagulation of the modified polyamide resin under the influence of aluminum polyoxychloride is multi-stage and ends with the complete deposition of adhesive particles at a system pH of 7.05, which corresponds to an electrolyte consumption of 0.051 g Al2O3/g of resin. The composition of the adhesive deposit formed under such conditions is as follows: aluminum-resin complexes (aluminum resinates and products of the interaction of aluminum ions with modified polyamino- amides) – 88.50 % wt.; free resin acids – 11.47 % wt. Further introduction of the electrolyte into the dispersed system leads to the protonation of the amino groups of modified polyaminoamides and aluminum-resin complexes, which provides with a positive charge. Due to its composition and the ongoing coagulation processes, the modified polyamide resin has a waterrepellent and strengthening effect on paper pulps in a wide pH range (5.8–7.5). Sequential introduction of resin into waste paper suspensions in an amount of 0.25 % of absolutely dry fiber and aluminum polyoxychloride until the paper pulps are achieved makes it possible to improve the hydrophobic and physical-mechanical properties of paper by 70.2–87.2 and 19.5–23.2 %, respectively.

The Institute for Nuclear Problems of the Belarusian State University (INP BSU) has developed equipment and optimized the technology for synthesizing boron-doped pyrocarbon, a material for application in heart valve endoprostheses.The purpose of this work was to evaluate the general and biochemical blood tests, mass coefficients of animal organs and the dynamics of reactions of rat tissues to implantation of pyrocarbon material in the subcutaneous tissues of the interscapular region. Animals were monitored for 90 days. According to the morphometric data, the boron-doped pyrocarbon, synthesized in INP BSU, was found to be non-irritating to the tissue in comparison with the control sample during all periods of observation. There was no significant effect of implantation of pyrolytic carbon on the parameters of the blood general and biochemical analysis in rats compared with healthy animals. The results of necropsy showed that the mass of organs and mass coefficients of animals did not deviate from the physiological norm during different periods of pyrocarbon sample implantation.Thus, the boron-doped pyrocarbon material synthesized in INP BSU can be used for manufacturing heart valve endoprostheses.

The gut microbiota plays an important role in the formation of the body’s regulatory systems (nervous, endocrine, immune), which is especially important at an early age. Hence, gut dysbiosis can lead to an impaired development of both the intestinal microbiota and these regulatory systems. Prebiotics can have a positive effect on the development of the intestinal microbiome, which can correct negative changes.The aim of this study is to investigate the features of development of antibiotic-associated dysbiosis in the early postnatal period in rats and to evaluate the effect of 2′-fucosyllactose in health and during dysbiosis.The study was conducted on Wistar rats aged 12–26 days. To develop dysbiosis at an early age, the following mixtures were used: a mixture of ampicillin trihydrate 75 mg/kg and metronidazole 50 mg/kg and a mixture of amoxicillin 30 mg/kg and cephalexin 20 mg/kg for three days, starting on the 12th day of life. As a prebiotic 2′-fucosyllactose at a dose of 1 g/kg was used, starting on the 12th day and to the last experiment day.In healthy animals, there is a decrease in the gut content of Bifidobacterium spp. and Enterococcus spp. at the age of 26 days. A mixture of ampicillin trihydrate 75 mg/kg and metronidazole 50 mg/kg leads to gut dysbiosis – growth suppression of bifidobacteria, lactobacilli and enterococci. After the end of antibiotics application and continued lactation, the titer of the described bacteria is restored. 2′-fucosyllactose has an effect on the preservation of the titer of Bifidobacterium spp. and Enterococcus spp., both in healthy animals and after early dysbiosis.Our results indicate that antibiotic-associated dysbiosis at an early age is characterized by a temporary but powerful effect. At the same time, the use of 2′-fucosyllactose leads to preserving important probiotic groups of intestinal bacteria, both in health and after dysbiosis.

Published: November 2024

The antihypoxic effect of a combination of bemethyl and thymoquinone after single intraperitoneal injection was studied in a model of hypercapnic hypoxia in a hermetic volume in mice. Thymoquinone had a dose-dependent protective effect by increasing the resistance of animals to hypoxia. At a dose of 10 mg/kg, it increased the life expectancy by 75.9 % compared with the control group, and at a dose of 30 mg/kg – by 90.2 %. The average effective dose of thymoquinone calculated by the regression analysis in this model was 14.1 mg/kg and the average effective dose of bemethyl was 148 mg/kg. As part of a combination of bemethyl and thymoquinone in the ratio of 5 : 1, the activity of the compounds increases significantly, ED50 of bemethyl decreases to 39.0 mg/kg, the same indicator for thymoquinone becomes 7.8 mg/kg. Administration of a combination of 100 mg/kg of bemethyl and 20 mg/kg of thymoquinone to mice leads to increasing their lifespan under the standard hypoxic conditions up to 41.2 ± 5.7 minutes, which is 120.5 % more than in animals receiving placebo. The analysis of pharmacodynamics of a combination of drugs according to T. Chou showed an additive type of interaction typical for compounds with different mechanisms of primary action. It was established that a combination of bemethyl and thymoquinone in the weight ratio of 5 : 1 demonstrate synergism, which makes it possible to reduce 1.8–4.0 times the doses of components in their combined use.
A la sombra de la violencia. Las experiencias de las maestras rurales durante el Movimiento Cristero en Michoacán, 1921-1929
Authors: Rojas Rodríguez Julio Alberto 
Published: November 2024

El objetivo de este artículo es analizar las experiencias de las maestras rurales en Michoacán durante el Movimiento Cristero (1926-1929), con el fin de comprender el contexto de violencia que prevaleció en torno a su labor educativa. Con ello se busca contribuir a la historiografía de la educación, al visibilizar el papel de las mujeres en la construcción del sistema educativo nacional, ya que frecuentemente han sido excluidas o minimizadas en los estudios de corte histórico. En esta investigación se busca demostrar que, como resultado de la federalización de la educación en la entidad, impulsada por el gobierno federal a través de la Secretaría de Educación Pública (SEP), el sistema educativo popular enfrentó múltiples adversidades que afectaron de manera significativa el desarrollo de las actividades escolares realizadas por las maestras rurales. Entre estas dificultades sobresalieron las acciones de resistencia de buena parte de la población, así como la intensa campaña de descrédito promovida por la jerarquía eclesiástica. Posteriormente, en medio del fuego cruzado entre cristeros y federales, las profesoras se vieron envueltas en un ambiente turbulento y hostil, toda vez que fueron consideradas como agentes oficiales de gobierno, lo cual las situaba entre los principales blancos de ataque. Sin embargo, algunas profesoras desafiaron la normativa oficial al incorporar contenidos religiosos en las escuelas oficiales, aspecto que no ha sido suficientemente abordado. El presente trabajo constituye un primer acercamiento al estudio de las maestras rurales michoacanas, dado que las investigaciones al respecto son limitadas. El texto se fundamenta en fuentes primarias novedosas, tales como el Archivo Histórico de la Secretaría de Educación Pública –actualmente bajo custodia del Archivo General de la Nación–, el Archivo Histórico Municipal de Morelia y el Archivo Histórico de la Casa de la Cultura Jurídica del Estado de Michoacán, así como en diversos estudios especializados.

Published: November 2024

Branding is an effort to build a positive identity and image for an institution. This research aims to understand the branding process carried out by the Dehasen Library through its Instagram account <a href="mailto:@perpustakaan_unived">@perpustakaan_unived</a>. Using Field Research methods with a qualitative approach, data was collected through three techniques: observation, interviews, and documentation. This study analyzed the digital marketing communication strategy of the library based on the SOSTAC theory. The research results indicate that although branding through Instagram is an essential effort to promote the library, the branding efforts by the Unived Library are not yet optimal. The Dehasen Library has implemented digital branding management steps including situation analysis, objective setting, strategy development, tactic determination, action implementation, and control. However, several indicators have not been properly implemented, such as communication, time-setting, program planning, and training. One of the reasons for this is the lack of attractive Instagram content management and the absence of dedicated human resources (HR) for managing the Instagram account. In summary, despite the Dehasen Library following some of the digital branding management steps according to the SOSTAC model, there are key aspects that need improvement to optimize digital branding. Recommendations for improvement include enhancing the quality and frequency of Instagram content, involving suggestions and feedback from followers to create more engaging content, and providing training for the staff responsible for managing social media. With these steps, the library is expected to increase the number of Instagram viewers and strengthen its positive image among students and the academic community.
Unveiling Awareness: Exploring Antibiotic Hypersensitivity among International Islamic University Malaysia (IIUM) Undergraduates in Kuantan, Pahang
Authors: Sepian Suhada , Ruslan Rusila 
Published: November 2024

Background: The condition known as antibiotic hypersensitivity, or antibiotic allergy, poses serious problems for the medical field. Despite its importance, little is known about the awareness of antibiotic hypersensitivity, particularly among undergraduate students in Malaysia. The purpose of this study is to assess the awareness of antibiotic hypersensitivity among IIUM Kuantan undergraduate students to improve drug allergy education and healthcare practices.
Methods: A general qualitative design was used to conduct the study. Semi-structured interviews were used to gather information about the awareness of antibiotic hypersensitivity. Due to their similar prevalence of antibiotic hypersensitivity, medical students served as a representative sample of Malaysia's adult population among undergraduate students from a variety of faculties. Thematic analysis was used to analyse the data.
Results: Six people in all were enlisted to take part in the study. Most of the participants were female Malay students at International Islamic University Malaysia (IIUM) Kuantan Campus, Pahang, Malaysia. Two primary themes emerged from the study: (1) Antibiotic hypersensitivity awareness and (2) Factors contributing to antibiotic hypersensitivity. This finding indicated that students' knowledge of antibiotic hypersensitivity is still lacking.
Conclusion: The research found evidence to suggest that additional intervention is necessary to raise awareness within the current community. Putting skill training into practice could be a good way to raise students' awareness in this area. On the other hand, more information is needed to determine the precise kind of skill training that Malaysia should adopt.

Published: November 2024

Background: The Objective Structured Clinical Examination (OSCE) is widely recognized in healthcare education for assessing clinical skills, yet its application in evaluating soft skills is still evolving. Soft skills, such as communication, empathy, and teamwork, are essential in patient-centered care but are not consistently included in OSCE assessment.
Methods: This systematic review aims to identify undergraduate nursing and healthcare students' perceptions of integrating soft skills and their assessment within OSCE. A comprehensive literature review was conducted, adhering to PRISMA guidelines, yielding 29 relevant studies published between 2017 and 2023. Studies were appraised using the Joanna Briggs Institute (JBI) Critical Appraisal Checklist for Quasi-Experimental Studies, the Critical Appraisal Skills Programme (CASP) Qualitative Research Checklist, and the Mixed Methods Appraisal Tool (MMAT).
Results: Three themes emerged from the analysis: (1) Perception and satisfaction of nursing students towards OSCE, (2) Perception and satisfaction of other healthcare students towards OSCE, and (3) Implementation of soft skills in OSCE. The findings indicate a positive reception of OSCE as an objective assessment tool, with students appreciating its structure and consistency. However, students highlighted challenges related to the time constraints and stress associated with OSCEs, particularly when soft skills are evaluated. Incorporating soft skills enhances students’ readiness for real-world clinical practice, yet its assessment remains inconsistent across studies.
Conclusion: Integrating soft skills into OSCE is critical for developing well-rounded healthcare professionals. Future research should focus on standardizing soft skill assessments in OSCE and exploring their impact on student performance and patient outcomes to meet the evolving demands of healthcare practice.

Published: November 2024

Background: Cervical cancer is mainly caused by the Human Papilloma Virus (HPV) and it is the most common malignancy among women worldwide with significant number of mortality rates. The objective of this study is to assess the level of knowledge and attitude regarding cervical cancer and pap smear screening and its association with sociodemographic characteristics among female students at International Islamic University Malaysia (IIUM) Kuantan Campus, Pahang.
Methods: A quantitative cross-sectional study using the convenience sampling method was conducted among 369 female undergraduate students of IIUM Kuantan Campus, from March to May 2023. Data were collected using a physical questionnaire which was available in the English Language that was distributed to all female undergraduate students in the campus. Data analysis was done by using SPSS version 27.
Results: This study demonstrated that the majority of the female students have average knowledge of cervical cancer (35.8%) and low knowledge of pap smear screening (37.9%). In addition, they have a low attitude toward cervical cancer (37.9%) and an average attitude toward pap smear screening (40.4%). It is also demonstrated that age, kulliyyah and year of study are significantly associated with knowledge level towards cervical cancer and pap smear screening (p<0.05). For attitude level of cervical cancer, there is a significant association between kulliyyah, family history of cancer and family history of cervical cancer (p<0.05). In addition, there is a significant association between year of study and family history of cervical cancer towards attitude level of pap smear screening (p<0.05). This study also demonstrated that most of the participants are unaware if vaccinating males can reduce the incidence of cervical cancer or not (57.2%), agreed that a woman who had a hysterectomy performed does not need to do a pap smear anymore (55.8%), which is incorrect, agreed that they feel shy, embarrassed and reluctant during pap smear test examinations (46.1%) and they afraid the results may show that they are positive for cancer (54.7%),
Conclusion: Hence, it is imperative to plan and implement targeted health promotion initiatives aimed at elevating the knowledge and reshaping the attitudes of female undergraduates pertaining on cervical cancer and the importance of pap smear screening test.
