The chemical composition of Sedum ewersii Ledeb., a plant indigenous to Kazakhstan and traditionally utilized in folk medicine, was comprehensively investigated, with a focus on its various plant parts. Fresh samples collected in May 2023 from the Almaty region underwent hydrodistillation to extract volatile components, followed by analysis using gas chromatography coupled with mass spectrometric detection, which identified a total of 71 compounds across different plant parts, including the root (underground part), root (aerial part), leaf, stem, and flowering aerial part. The predominant biologically active compound identified across all plant parts was Ethyl α-D-glucopyranoside. Monoterpenes, recognized as primary secondary metabolites, were notably abundant in each plant part, with varying compositions: the root (underground part) contained 28.58% aliphatic monoterpenes, 54.41% oxygenated monoterpenoids, 1.42% diterpenoids, and 15.59% other compounds; the root (aerial part) exhibited 1.34% aliphatic monoterpenes, 31.28% oxygenated monoterpenoids, 6.16% diterpenoids, and 61.22% other compounds; the stem and leaves showed 3.06% aliphatic monoterpenes, 21.49% oxygenated monoterpenoids, 17.99% diterpenoids, and 57.46% other compounds; and the flowering aerial part displayed 8.20% aliphatic monoterpenes, 53.18% oxygenated monoterpenoids, 23.75% diterpenoids, and 14.87% other compounds. Diterpenes, particularly Phytol, were prominently present in the leaf, stem, and flowering aerial parts. Additionally, a diverse array of organic acids, ketones, and phenolic compounds were identified across the plant parts, each potentially offering distinct pharmacological benefits. The presence of exclusive compounds in specific plant parts, such as Dihydroxyacetone in the root (aerial part), underscored the pharmacological diversity of S. ewersii. This study provides valuable insights into the chemical diversity and pharmacological potential of S. ewersii, suggesting promising applications in pharmaceutical and medicinal fields. Further research aimed at elucidating the individual and synergistic pharmacological effects of these compounds is crucial to fully harness the therapeutic benefits of this plant.

The article examines the current status of populations of Phedimus hybridus (L.) 't Hart (also known as Sedum hybridum L. and Aizopsis hybrida (L.) Grulich) and Hylotelephium ewersii (Ledeb.) H. Ohba (formerly Sedum ewersii Ledeb.) in the Kok-Zhailau Gorge, part of the flora of the Ile Alatau. The study explores the biology of these species, including their population dynamics and life forms, as well as their ecological responses to specific ecological-cenotic conditions. P. hybridus is valued in traditional medicine for its diverse therapeutic properties, such as anti-inflammatory effects, stimulation of the nervous system, antidepressant and wound-healing actions, and inhibition of leukocytosis. In contrast, H. ewersii is commonly cultivated as an ornamental plant. The article also includes a taxonomic, ecological, and geographical analysis of the flora associated with the populations of P. hybridus and H. ewersii in the Kok-Zhailau Gorge.

Public health risks associated with antibiotic residues in poultry food products

Antibiotic residues in the poultry food products pose significant public health risks, contributing to the growing global challenge of antimicrobial resistance (AMR). This paper focuses on the public health risks associated with antibiotic residues in poultry food products. The study found that the routine use of antibiotics in poultry farming for growth promotion and disease prevention has resulted in the accumulation of residues in food products, which can lead to adverse health effects in consumers. These include allergic reactions, toxicity, disruption of gut microbiota, and the promotion of antibiotic-resistant bacteria. Long-term exposure to antibiotic residues, even at low levels, exacerbates these risks, impacting not only individual health but also broader public health systems. Regulatory frameworks, such as the establishment of maximum residue limits (MRLs) and stringent monitoring, are crucial for ensuring food safety. However, there is a pressing need for alternative strategies in poultry production that reduce reliance on antibiotics while maintaining animal health. Public education, antimicrobial stewardship, and sustainable farming practices are vital to mitigate the risks posed by antibiotic residues. The global effort to address AMR should involve coordinated actions among stakeholders, including policymakers, farmers, and healthcare providers, to protect both food safety and public health. Future research needs to prioritize the development of alternative therapeutics and innovative farming practices to minimize the presence of antibiotic residues in poultry products. • Use of antibiotics in poultry could boost growth and wellbeing but also pose public health risks. • Ongoing misuse is driving an increase in environmental and organismal antibiotic residues. • Antibiotic residues can accumulate through the food chain with known and unknown One Health effects. • Factors affecting residues include antibiotic type, dosage, withdrawal and cultural practices. • Cooking reduces antibiotic residues, but consumption of poultry products may cause allergic and microbiota effects.

This study investigates the removal of fluoranthene (Flu) from vehicle-wash wastewater (VWW) using biochar (EWB) derived from eucalyptus wood waste. Analytical techniques such as surface area analysis (SAA), scanning electron microscopy (SEM), and fourier transform infrared spectroscopy (FT-IR) were employed to characterize the EWB. Optimal conditions for Flu adsorption (98.80%) were determined as 40 ppm initial concentration, 60 minutes contact time, pH 5, 60°C, and 0.4 g adsorbent dosage. The adsorption process was evaluated using kinetic models and isotherms, showing that Flu adsorption onto EWB follows a pseudo-second order kinetic model. The Langmuir isotherm provided the best fit for the experimental data. Thermodynamic analysis revealed that the adsorption process is exothermic and spontaneous, as indicated by the values of entropy (ΔS°), Gibbs free energy (ΔG°), and enthalpy (ΔH°). A comparative analysis with commercial adsorbents demonstrated the high efficacy of EWB in removing Flu from industrial wastewater, achieving over 98% efficiency.

ГЕНОМНАЯ ОЦЕНКА ГЕНЕТИЧЕСКОГО РАЗНООБРАЗИЯ ПОПУЛЯЦИЙ CALLIGONUM LEUCOCLADUM (SCHRENK) BUNGE ЛЕКАРСТВЕННОГО В ПУСТЫНЕ КЫЗЫЛКУМ C. LEUCOCLADUM

Calligonum leucocladum (Schrenk) Bunge - экологически важный пустынный кустарник, адаптированный к засушливым и полузасушливым условиям Центральной Азии. Эта работа впервые предлагает комплексную оценку генетического разнообразия, структуры популяции и фитохимической изменчивости вида с использованием генотипа SNP с высоким разрешением и хемометрического профиля. Было проанализировано 150 особей из трех географически разделенных популяций (P1, P2 и P3) пустыни Кызылкум и прилегающих регионов. Анализ распада связывающего равновесия (LD) показал, что популяция P3 характеризуется самым высоким уровнем рекомбинации (r2 резко падает на 10 кб), в то время как P2 демонстрирует сильную LD на больших расстояниях, что указывает на среднюю генетическую изоляцию. Базовый координатный анализ (PCoA) объяснил 76,55% общей генетической изменчивости и подтвердил фактическую дифференциацию P1, в то время как P2 и P3 показали генетическое родство. Анализ минимального связующего дерева (MST) дополнительно подтвердил эти закономерности. Фитохимический профиль впервые выявил популяционные различия в общих фенолах, флавоноидах и антиоксидантных способностях, которые соответствуют генетической структуре. Результаты показывают, что географическая изоляция, фрагментация среды обитания и экологический стресс способствуют расхождению популяций. Высокое генетическое и биохимическое разнообразие популяции P3 определяет ее как потенциальный резервуар адаптивных признаков. Эта работа является ценной основой для планирования природоохранных мероприятий и экологического восстановления пустынной флоры.
