Iron tailings from the mining process occupy vast land areas and pose a significant ecological risk. In order to reuse iron tailings resources and carry out in situ ecological restoration of a mine, in this study, a medium of mixed iron tailings and mining topsoil (m:m = 3:1) was used to plant landscape grasses, including Lolium perenne L. (L. perenne), Pennisetum alopecuroides (L.) Spreng. (P. alopecuroides), Melilotus officinalis (L.) Lam. (M. officinalis), and Medicago sativa L. (M. sativa). Biochar and chicken manure were used as biochar organic fertilizers and indigenous microorganisms were isolated from the rhizosphere soil of tested grasses. They were applied to enhance landscape grass growth by regulating rhizosphere microbial communities and nutrient conditions. The results showed that the biochar organic fertilizers significantly promoted the growth of the four landscape grasses, notably P. alopecuroides, increasing plant height, root length, root weight, and leaf fresh weight by 169%, 60%, 211%, and 388%, respectively. Additionally, L. perenne exhibited the greatest height increase (10%) following the application of bacterial solutions. Moreover, indigenous bacterial solutions enhanced chlorophyll content and phenylalanine ammonia-lyase (PAL) activity, with P. alopecuroides showing the highest chlorophyll increase of 58% and M. sativa exhibiting a 30.58% rise in PAL activity. The biochar organic fertilizer also significantly elevated soluble protein content in P. alopecuroides and M. sativa by 195% and 152%, respectively. It also effectively enhanced peroxidase (POD) activity in Poaceae grasses by 120% to 160%. After adding indigenous microorganisms, the rhizosphere soil of the landscape grass showed the highest Shannon–Wiener diversity index, reaching 3.561. The rhizosphere soil of M. officinalis had the highest microbial richness, with a value of 39. Additionally, the addition of indigenous microorganisms increased the nitrogen, phosphorus, and potassium content of the four plants by 8–19%, 6–14%, and 8–18%, respectively. This study offers a new approach for managing mining waste and ecological restoration in mining areas.

Soil remediation for cadmium (Cd) toxicity is essential for successful tobacco cultivation and production. Melatonin application can relieve heavy metal stress and promote plant growth; however, it remains somewhat unclear whether melatonin supplementation can remediate the effects of Cd toxicity on the growth and development of tobacco seedlings. Herein, we evaluated the effect of soil-applied melatonin on Cd accumulation in tobacco seedlings, as well as the responses in growth, physiological and biochemical parameters, and the expression of stress-responsive genes. Our results demonstrate that melatonin application mitigated Cd stress in tobacco, and thus promoted plant growth. It increased root fresh weight, dry weight, shoot fresh weight and dry weight by 58.40%, 163.80%, 34.70% and 84.09%, respectively, compared to the control. Physiological analyses also showed significant differences in photosynthetic rate and pigment formation among the treatments, with the highest improvements recorded for melatonin application. In addition, melatonin application alleviated Cd-induced oxidative damage by reducing MDA content and enhancing the activities of enzymatic antioxidants (CAT, SOD, POD and APX) as well as non-enzymatic antioxidants (GSH and AsA). Moreover, confocal microscopic imaging confirmed the effectiveness of melatonin application in sustaining cell integrity under Cd stress. Scanning Electron Microscopy (SEM) observations illustrated the alleviative role of melatonin on stomata and ultrastructural features under Cd toxicity. The qRT-PCR analysis revealed that melatonin application upregulated the expression of photosynthetic and antioxidant-related genes, including SNtChl, q-NtCSD1, NtPsy2 and QntFSD1, in tobacco leaves. Together, our results suggest that soil-applied melatonin can promote tobacco tolerance to Cd stress by modulating morpho-physiological and biochemical changes, as well as the expression of relevant genes.

Published: October 2024

Phytohormones are organic compounds produced in trace amounts within plants that regulate their physiological processes. Their physiological effects are highly complex and diverse. They influence processes ranging from cell division, elongation, and differentiation to plant germination and rooting. Therefore, phytohormones play a crucial regulatory role in plant growth and development. Recently, various studies have highlighted the role of PHs, such as auxin, cytokinin (CK), and abscisic acid (ABA), and newer classes of PHs, such as brassinosteroid (BR) and peptide hormone, in the plant responses toward environmental stresses. These hormones not only have distinct roles at different stages of plant growth but also interact to promote or inhibit each other, thus effectively regulating plant development. Roots are the primary organs for water and mineral absorption in plants. During seed germination, the radicle breaks through the seed coat and grows downward to form the primary root. This occurs because the root needs to quickly penetrate the soil to absorb water and nutrients, providing essential support for the plant’s subsequent growth. Root development is a highly complex and precisely regulated process influenced by various signals. Changes in root architecture can affect the plant’s ability to absorb nutrients and water, which in turn impacts crop yield. Thus, studying the regulation of root development is of great significance. Numerous studies have reported on the role of phytohormones, particularly auxins, in root regulation. This paper reviews recent studies on the regulation of root development by various phytohormones, both individually and in combination, providing a reference for researchers in this field and offering perspectives on future research directions for improving crop yields.

Since its introduction into Europe in the first half of the 20th century, Cryphonectria parasitica has been gradually spreading across the natural range of the sweet chestnut (Castanea sativa Mill.), infecting the trees and causing lethal bark cankers. Serendipitously, a hyperparasitic Cryphonectria hypovirus 1 (CHV1), which attenuates C. parasitica virulence in combination with more tolerant European chestnut species, was able to ward off the worst effect of the disease. In North America, unfortunately, the native Castanea dentata is now functionally extinct since it occurs only as root sprouts in eastern deciduous forests where it was once dominant. In our work, we investigated changes in C. parasitica populations over time and the regional variability in chestnut populations’ tolerance toward the blight disease. While vegetative compatibility (vc) type diversity and prevalence of hypovirulence remained similar as in previous studies, in the Buje population, unlike in previous studies, we were unable to find any hypovirulent fungal strains. The most common vegetative compatibility types (vc types) were EU-1, EU-2 and EU-12. However, several rare EU-types were found, including one previously unreported: EU-46. By inoculating several C. parasitica strains on tree stems from several chestnut populations, we observed that the induced lesion size was affected by the type of inoculum (CHV1-free or CHV1-infected), genotype-related individual chestnut stem and chestnut stem population of origin-related variability. The largest lesions were induced by CHV1-free fungal isolate DOB-G: 20.13 cm2 (95% C.I. 18.10–22.15) and the smallest by CHV1-infected L14/EP713: 2.49 cm2 (95% C.I. 1.59–3.39). Surprisingly, the size of the lesions induced by other CHV1-infected strains fell somewhere in between these extremes. The size of induced lesions was dependent on the population of origin as well and ranged from 11.60 cm2 (95% C.I. 9.87–13.33) for stems from the Moslavačka gora population to 17.75 cm2 (95% C.I. 15.63–19.87) for stems from Ozalj.

Green fiber (GF) is a naturally colored fiber. A limited understanding of its color formation mechanism restricts the improvement of colored cotton quality. This experiment used upland cotton green fiber germplasm 1-4560 and genetic inbred line TM-1; the lipid profiles of green fibers at 30 (white stage) and 35 days post-anthesis (DPA) (early greening stage), as well as those of TM-1 at the same stages, were revealed. Among the 109 differential types of lipids (DTLs) unique to GF, the content of phosphatidylserine PS (16:0_18:3) was significantly different at 30 and 35 DPA. It is speculated that this lipid is crucial for the pigment accumulation and color formation process of green fibers. The 197 DTLs unique to TM-1 may be involved in white fiber (WF) development. Among the shared DTLs in GF35 vs. GF30 and WF35 vs. WF30, sulfoquinovosyldiacyl-glycerol SQDG (18:1_18:1) displays a significant difference in the content change between green fibers and white fibers, potentially affecting color formation through changes in content. The enriched metabolic pathways in both comparison groups are relatively conserved. In the most significantly enriched glycerophospholipid metabolic pathway, 1-acyl-sn-glycero-3-phosphocholine (C04230) only appears in white cotton. This indicates differences in the metabolic pathways between white and green fibers, potentially related to different mechanisms of color formation and fiber development. These findings provide a new theoretical basis for studying cotton fiber development and offer important insights into the specific mechanism of green fiber color formation.

It is a consensus that Earth’s climate has been warming. The impact of global warming is asymmetric, that is, there is more substantial warming in the daily minimum surface air temperature and lower warming in the maximum surface air temperature. Previous studies have reported diurnal temperature differences greatly affecting winter wheat yield. However, only a few studies have investigated the impact of global warming on the growth and yield of winter wheat, yet the influence of night warming on quality has not been deeply evaluated. In this study, two wheat cultivars were used as materials: Jimai 44 (JM44) with strong gluten and Jimai 22 (JM22) with medium gluten, to explore the effects of high nighttime temperatures (HNTs) on the growth, yield, and quality of wheat. The results show that HNTs significantly shortened seedling emergence and anthesis periods in both cultivars compared with ambient temperatures (ATs). In addition, HNTs increased the respiration rate at anthesis and grain-filling stages, impeding wheat pollination and grain maturity. HNTs also accelerated leaf senescence and increased the number of sterile spikelets and plant height, but decreased the effective tiller number, the number of spikes per unit area, and grains per spike. As a result, the grain yield of JM22 and JM44 was decreased by 24.6% and 21.2%, respectively. Moreover, HNTs negatively influenced the flour quality of the two wheat cultivars. The current findings provide new insights into the effects of HNTs on the growth, development, yield, and quality of different wheat genotypes during the whole growth period.

Published: October 2024

Owing to the limitations of physical experiments on heavy oil, this study establishes a mathematical model for heavy oil–water two-phase flow based on the theory of multiphase flow, considering factors such as heavy oil viscosity, mixed flow velocity, and inlet water cut. Through transient calculations of 650 groups of heavy oil–water two-phase flows based on this model, six typical heavy oil–water two-phase flow patterns were identified by monitoring flow pattern cloud images, liquid holdup, and the probability density function (PDF) of liquid holdup: water-in-oil bubble flow, transitional flow, water-in-oil slug flow, oil-in-water bubble flow, oil-in-water very fine dispersed flow, and water-in-oil core-annular flow. Five sets of flow pattern maps for a heavy oil–water two-phase flow with different viscosities were established based on the inlet water cut and mixed flow velocity. The results showed that different heavy oil viscosities lead to different oil–water two-phase flow patterns. When the heavy oil viscosity is 100 mPa·s, the flow patterns include water-in-oil bubble flow, transitional flow, water-in-oil slug flow, oil-in-water bubble flow, and oil-in-water very fine dispersed bubble flow. When the heavy oil viscosity reaches 600 mPa·s, a water-in-oil core-annular flow appears, and the oil-in-water very fine dispersed bubble flow disappears. After the heavy oil viscosity exceeds 1100 mPa·s, the oil-in-water bubble flow disappears. Among the different flow patterns, the range of the water-in-oil slug flow is most affected by the viscosity and flow velocity. The greater the heavy oil viscosity, the larger the range. When the viscosity remained constant, a larger flow velocity resulted in a smaller range. The accuracy of the flow pattern predictions in the maps was verified by comparing them with field production data, confirming that the research results can provide a theoretical basis for understanding oil–water two-phase flow patterns in heavy oil wellbores.
The Involvement of the Catholic Laity in the Promotion of Peace
Authors: Ujházi Lóránd
Published: October 2024

In accordance with their constitutional prerogatives, members of the Church engage in activities that align with their designated roles and responsibilities. A review of both the history of the Church and the documents in force reveals that the Church, in its broadest sense, is concerned with the promotion of peace. Such areas are, by definition, those which fall within the purview of laypeople. The Second Vatican Council accorded particular attention to the promotion of social justice and peace, as well as to the apostolate of lay faithful. Consequently, the two areas were brought into contact and underwent further development. This paper presents the historical trajectory that has culminated in the most comprehensive positioning of the laity in the promotion of social justice, elucidating the legal distinctions pertaining to the most prevalent methods through which they can promote peace.

The Republic of Bulgaria regulates the quality of surface waters for drinking and domestic purposes, monitoring anions like F-, Cl-, Br-, I-, BrO3-, NO2-, NO3-, SO42-, PO43-, and SCN-. The presence of NO3- and NO2- in water is undesirable, as they have a harmful effect on human health. It is also well known that CN- as opposed to SCN- has acute toxic and lethal effects on living organisms including humans. In the present study, an instrumental method was developed and optimized for the separation and quantification of inorganic anions in surface and drinking water using ion chromatography. The analytical characteristics of the proposed instrumental method were determined. The oxidation of CN- to OCN- was investigated, and the optimal experimental conditions for the oxidation were established. The achieved low LOD and LOQ of the analyzed inorganic anions allows their detection and quantification in surface and drinking waters. The applicability of the proposed chromatographic method was determined in the analysis of surface and bottled waters. The analyzed anions in bottled waters were close to the label's values, only one spring water showed significant deviations.

Published: October 2024

Este artigo analisa a evolução da taxa de homicídios em Curitiba, Paraná, entre 2012 e 2022, destacando o impacto das políticas de segurança pública implementadas nesse período. O estudo se baseia em dados do Atlas da Violência e fontes oficiais para investigar as variações nas taxas de homicídios e outros crimes violentos, como roubos e latrocínios. Curitiba apresentou uma redução significativa nas taxas de homicídios, de 35,5 para 24,6 por 100 mil habitantes, graças ao aumento do policiamento ostensivo e à modernização das forças de segurança. No entanto, o artigo também explora os desafios dessas políticas, como o deslocamento da criminalidade para áreas menos monitoradas e a necessidade de complementar o policiamento com políticas de inclusão social. Conclui-se que, embora o policiamento ostensivo tenha mostrado eficácia na redução dos homicídios, é necessário uma abordagem integrada, que envolva desenvolvimento social e policiamento comunitário para garantir a sustentabilidade dos resultados.

Данная теория является развитием Общей когнитивной теории. Общая когнитивная теория описывает принципы построения психики и взаимодействия людей в результате которого возникает культура. Теория говорит о том, что наша психика представляет собой иерархическую систему взаимно возбуждаемых групп (популяций) нейронов, сохраняющих последовательности сигналов рецепторов, совпадающих по времени с возбуждением популяций клеток, отвечающих за инстинкты (эмоции). Но в Общей когнитивной теории не описывается, каким именно образом сохраняются последовательности афферентных сигналов от рецепторов, последовательности таких последовательностей и следующие уровни иерархии. Данная статья, посвящена конкретным механизмам сохранения таких последовательностей.

This theory is a development of the General Cognitive Theory. General cognitive theory describes the principles of building the psyche and the interaction of people as a result of which culture arises. The theory suggests that our psyche is a hierarchical system of mutually excited groups (populations) of neurons that store sequences of receptor signals that coincide in time with the excitation of cell populations responsible for instincts (emotions). But the General Cognitive Theory does not describe exactly how the sequences of afferent signals from receptors, the sequences of such sequences, and the next levels of the hierarchy are stored. This article is devoted to specific mechanisms for saving such sequences.

Поставлен вопрос относительно предпочтения левой или правой сторон в вестибулярной системе. Важным отличием вестибулярной системы от других систем является то, что она не имеет первичной локализации в коре головного мозга. Цель исследования: изучить специфику латеральных предпочтений в вестибулярной и слуховой системе в онтогенезе. Было обследовано 383 ребёнка (290 мальчиков, 93 девочки) в возрасте от 1,1 до 13,7 года (средний возраст 5,5±2,4 года; формат M±SD). Все дети посещали дошкольные учреждения общеразвивающего вида или общеобразовательные школы. Для проведения исследования были получены разрешения родителей. В процессе исследования был использован следующий набор методик: регистрация акустических стволовых вызванных потенциалов с использованием метода VI пика; оценка функции полукружных каналов вестибулярного аппарата путём регистрации длительности поствращательного нистагма, оценка отолитовой функции вестибулярного аппарата проводилась методом цервикальных вестибулярных миогенных вызванных потенциалов. Для оценки изменений выраженности асимметрии в онтогенезе был применён многомерный анализ. Данные свидетельствуют о том, что асимметрия в слуховой сфере закладывается при рождении, тогда как асимметричные изменения нистагма и вестибулярной функции постепенно усиливаются и связаны с постепенным преобладанием правого полушария в переработке информации.

The question was raised regarding the preference of the left or right sides in the vestibular system. An important difference between the vestibular system and other systems is that it does not have a primary localization in the cerebral cortex. The purpose of the study: to study the specifics of lateral preferences in the vestibular and auditory systems in ontogeny. We examined 383 children (290 boys, 93 girls) aged 1.1 to 13.7 years (mean age 5.5±2.4 years; M±SD format). All children attended preschool institutions of a general developmental type or general education schools. Parental permission was obtained for the study. During the study, the following set of techniques was used: registration of acoustic stem evoked potentials using the VI peak method; assessment of the function of the semicircular canals of the vestibular apparatus by recording the duration of postrotational nystagmus, assessment of the otolithic function of the vestibular apparatus was carried out by the method of cervical vestibular myogenic evoked potentials. To assess changes in the severity of asymmetry in ontogeny, a multivariate analysis was used. The data suggest that asymmetry in the auditory sphere is established at birth, while asymmetric changes in nystagmus and vestibular function gradually increase and are associated with the gradual predominance of the right hemisphere in information processing.

В статье приведён обзор диагностических методик с использованием стабилометрических критериев у детей с нарушениями двигательных функций, которые обусловлены отставанием созревания структур головного мозга, ответственных за реализацию процессов управления построением движений, что приводит к нарушению тонкой моторики и поддержания статического и динамического баланса тела. Стабилометрия является методом функциональной диагностики опорно-двигательной системы и может быть использована в качестве объективного метода оценки развития детей младшего школьного возраста. Стабилометрическое тестирование подтвердило актуальность использования данного метода для диагностики диспраксии, а также выявления дефицита когнитивных функций.

The article provides a review of diagnostic techniques using stabilometry criteria in children with impaired motor functions, which are caused by delayed maturation of the brain structures responsible for the realization of control processes of movement construction, which leads to impairment of fine motor skills and maintenance of static and dynamic body balance. Stabilometry is a method of functional diagnostics of the musculoskeletal system and can be used as an objective method for assessing the development of children of primary school age. Stabilometry testing confirmed the relevance of using this method for diagnosing dyspraxia as well as detecting cognitive deficits.

Останні дослідження в галузі стоматології зосереджені на впливі оксидативного стресу на запальні процеси після фіксації імплантатів, що може спричиняти ускладнення. Тому актуальним є пошук нових терапевтичних підходів для мінімізації цих негативних наслідків і забезпечення антиоксидантного захисту. Метою дослідження було оцінити біохімічні маркери антиоксидантно-прооксидантної системи в яснах щурів при фіксації імплантату та вплив лікувальних заходів на ці маркери за допомогою експерименту. Матеріали та методи. У дослідженні було використано 45 щурів самців 7-місячного віку, середньою вагою 340-370 г. Тваринам дослідних груп фіксували імплантат, і з наступного дня перорально вводили комплекс препаратів; контрольній групі у тому ж об’ємі вводили воду. Щурів розподілили на 3 групи. По закінченні експерименту проводили відсепаровування ділянки слизової оболонки ясен для біохімічних досліджень: визначали показники антиоксидантно-прооксидантної системи. Статистично значущу відмінність між альтернативними кількісними ознаками з розподілом, відповідним нормальному закону, оцінювали за допомогою t-критерію Стьюдента. Різницю вважали статистично значущою при р<0,01. Результати дослідження. Дані демонструють, що фіксація імплантату викликає значні зміни в яснах щурів: наявність запальних процесів, інтенсифікацію процесів ПОЛ, а також одночасне зниження активності антиоксидантного захисту в тканинах ясен. Застосування розробленого лікувального комплексу препаратів на тлі фіксації імплантату призводить до нормалізації цих показників, що практично відповідають показникам інтактної групи. Висновки. Отримані результати свідчать про розвиток оксидативного стресу і запального процесу в тканинах ясен після імплантації. Застосування лікувального комплексу препаратів ефективно знижує оксидативний стрес та відновлює антиоксидантний захист, що свідчить про його потенційну ефективність у профілактиці та лікуванні запальних ускладнень після імплантації, з перспективою впровадження в клінічну практику.
