Published: December 2024

IntroductionFruits are vital for promoting human health, as well as providing nutrients and other compounds linked to protection against many different diseases. Loengo (Anisophyllea boehmii Engl.) produces an edible stone fruit, plum-shaped (drupe), dark blue and maroon or carmine in the ripening stage, which is generally, consumed fresh in the production areas. Characterization of this fruit will contribute to estimate its nutritional and pharmaceutical potential impact. The present work aimed at the physic-chemical, nutritional and antioxidant activity characterization of loengo fruit.MethodsSoluble solid contents (SSC) in the pulp were assessed in juice, at room temperature. Total protein was determined using the Dumas method. In what concerns the mineral composition were determined by ICP-OES. Organic acids identification and quantification was accomplished using a high-performance liquid chromatography (HPLC) system. The total polyphenol contents (TPC) were determined in 96-well microplate assays. Antioxidant activity were determined by 2,2-diphenyl-1-picrylhydrazyl (DPPH) and the ferric reducing antioxidant power (FRAP) assay.Results and discussionComposition, in terms of fresh matter is as follows: pulp soluble sugar content (refractometer) is 19.5% ± 0.02%, and pulp titratable acidity 1.2% ± 0.1% expressed in citric acid; total protein content is 7.4% ± 0.02%, 8.0% ± 0.1%, 16.9% ± 0.2%, for the peel, pulp and seed, respectively. In what concerns the mineral composition, the results obtained show that it is a good source of minerals, mainly potassium and phosphorus, but also calcium, sulfur, and magnesium, with the pulp richer in potassium, the seed in phosphorus, and the peel in calcium. As expected, the pulp showed the highest total soluble sugar content, whereas the seed had the lowest. The main sugars found in the pulp were glucose and fructose. In the peel citric acid was the main organic acid found, together with malic, oxalic, and ascorbic acids. Most antioxidant activity was found in the seed. The results of this work provide important basic information to recommend the consumption of this fruit for its sweet taste, chemical and nutritional composition, and, most of all, for its richness in total phenolic compounds for it potential to formulate nutraceutical foods.

ObjectivesLimited data exists on attitudes and practices of young men in tertiary institutions towards contraception. This study assesses attitudes and practices regarding contraception among male students in a tertiary educational institution in northwestern Nigeria, identifying factors influencing these attitudes.MethodsThis cross-sectional study conducted from July to August 2021 at Kaduna Polytechnic, Nigeria, involved 160 male students chosen via multistage sampling. Structured questionnaires gathered information on socio-demographic characteristics, awareness, attitudes, and contraceptive practices. Analysis utilized SPSS version 23.0, employing descriptive statistics, bivariate, and multivariable logistic regression analyses to determine significant factors influencing contraception attitudes.ResultsFindings revealed a mean respondent age of 25.4 ± 3.5 years, with most being single (71.3%) and 51.2% sexually active. While awareness of contraceptives was high (85.6%), almost half (46.7%) exhibited negative attitudes towards contraception. Common concerns included reliability, impact on sexual pleasure, and traditional gender norms. Only 35.8% had ever used contraception, primarily using withdrawal and male condoms. Significant factors influencing positive attitudes included being aged 18–24 years compared to 26–35 years (AOR = 2.66, 95% CI: 1.22–5.82).ConclusionCulturally sensitive interventions are vital for improving negative attitudes and low contraceptive use among male Nigerian youth.

Published: December 2024

Background/Objectives: Neisseria gonorrhoeae is the third most common sexually transmitted infection (STI), which may become untreatable soon if resistance continues to drastically increase. Due to increases in resistance to recommended antibiotics, alternative sources of novel compounds to combat this threat are being explored. Interestingly, marine sponges have proven to produce a plethora of bioactive compounds that display anticancer, antiviral, antifungal, and antibacterial activity. Methods: In this study, the extracts of the sponge collected from Saint Thomas, US Virgin Islands were examined to determine their antibacterial activity against E. coli, S. aureus, and N. gonorrhoeae. Results: The ethyl acetate sponge extracts significantly inhibited growth of N. gonorrhoeae, while none inhibited S. aureus and E. coli. The bioassay-guided purification of the ethyl acetate extract resulted in the isolation of 6-desmethyl-6-ethylspongosoritin A (1) and plakortone B (2). To determine if the pure sponge metabolite could improve the efficacy of ceftriaxone against a high-level ceftriaxone (HTX)-resistant gonococcal strain, an antibiotic checkerboard assay was done by combining various concentrations of either precursor fractions or the purified compound 2 with ceftriaxone. Plakortone B (2) and ceftriaxone acted in synergy against gonococcal strains and inhibited growth by increasing membrane permeability when exposed for 4 h and 24 h. Conclusions: This suggests that marine sponges may serve as a source for novel bioactive compounds against antibiotic-resistant strains of N. gonorrhoeae, as well as improve the efficacy of currently prescribed antibiotics.
STUDYING IMAGES-SYMBOLS AT UKRAINIAN LITERATURE LESSONS
Authors: BONDARENKO A. , BONDARENKO Y. 
Published: December 2024

Admitting that literature is an art of the word, we should acknowledge that students’ work at the level of language organization of the text, which includes images-symbols, is of great importance. The paper’s author reveals his own methodological and literature studies propositions concerning an important didactical problem, i.e. the complex study of images-symbols on the basis of chronotopical structure of literature sources, their ideas and themes, word expression of symbolical creations. The main idea of the paper is that comprehension of images-symbols, their contents and artistic value should be based on the complete systematic analysis of a piece of literature, being a part of it. Images-symbols should be treated as specific «debris» (H.-G. Gadamer) of an artistic structure of the text in which they are an organic part and therefore can be explained only as its component.
The author illustrates his statements with the help of enormous literature material, included to the school curriculum. This include works by T. Shevchenko («Caucasus»), P. Kulish («The Black Council»), I. Franko («Faded Leaves», «Jay’s Wing», «The Legend about Eternal Life»), M. Kotsiubynskyi («Intermezzo»), V. Stefanyk («The Stone Cross») etc. It is demonstrated on the example of some of these pieces of literature that symbolic images play a unifying and generalizing role in the organization of a literary text, ensuring the expression of author’s main ideas. This is why the scientist suggests studying symbolic images at the final stage of literary work analysis, when students have mastered the entire system of meanings, which are embedded in the text, and the specificity of their figurative expression with the help of many other means used by the writer. As a result, the study of symbols becomes a kind of climax in the comprehension of a literary source by schoolchildren, becoming the quintessence of the artistic picture that students are trying to master. Therefore participants of the educational process should be given the task to comprehend author’s understanding of key worldview phenomena, i.e. the images of cosmos (nature), God, man, society and nation.

ChatGPT in the Context of Scientific Communication
Authors: Tikhonova Elena V. 
Published: December 2024

Introduction: The growing interest in the potential use of ChatGPT in the field of educational and scientific communication has prompted close attention from the editors of scientific journals, administrators, and educators to limit its impact on potential users. It's clear that a total ban on using ChatGPT in the realities of modern society is impossible, underscoring the need to reach a consensus on acceptable boundaries for its use. Purpose: To describe the primary opinions of editors of scientific publications and publishers that have emerged around the mechanisms of using content generated by ChatGPT by authors of scientific article manuscripts. Focus and Boundaries of Neural Networks in the Context of Scientific Communication: The established status quo concerning the partially permissible reliance on content generated by ChatGPT in certain sections of a scientific manuscript, especially those containing less original content, is accompanied by a range of questions about the ethical aspects of involving artificial intelligence in the realm of scientific creativity. One such question pertains to illustrations created by artificial intelligence tools upon an author's request. Conclusions: Although there is no clear answer to many questions related to the prospects of using neural networks in scientific communication, monitoring the current consensus on the issue will allow researchers to adhere to journal policies, uphold the ethics of scientific communication, and avoid the imitation of creating scientific content.
