Приведены результаты расчетов экономической эффективности клонального микроразмножения лесных ягодных растений рода Vaccinium на примере выращивания в культуре in vitro клюквы болотной, брусники обыкновенной, голубики узколистной. В условиях повышения потребительского спроса на ягодную продукцию организация выращивания лесных ягодников путем создания промышленных плантаций имеет большое практическое значение для сохранения пищевых и лекарственных ресурсов леса и активизации их контролируемой заготовки в России. Традиционные методы вегетативного размножения лесных ягодных растений не обеспечивают стабильность результатов и являются трудозатратными при создании ягодных плантаций, поэтому необходимо использовать экономически эффективные и экологически безопасные технологии выращивания. Представлены данные по составу и структуре производственных затрат и себестоимости выращивания посадочного материала лесных ягодных растений рода Vaccinium в условиях культуры in vitro и в производственных условиях (в пересчете на 1 га плантационной площади). Показана экономическая эффективность производства (рентабельность - 187,7-475,4 %) с использованием метода клонального микроразмножения при получении посадочного материала лесных ягодных растений рода Vaccinium для промышленного выращивания.
The results of calculations of the economic efficiency of clonal micropropagation of forest berry plants of the genus Vaccinium are presented on the example of cultivation of European cranberry, lingonberry and narrow-leaved blueberry in in vitro. The organization of growing forest berries through the creation of industrial plantations is of great practical and relevant importance for the conservation of non-timber forest resources and the activation of their controlled harvesting in Russia in the context of increasing consumer demand for berry products. Traditional methods of vegetative reproduction of forest berry plants don’t provide stable results and are labor-intensive when creating berry plantations, and therefore this is necessary to use optimal cost-effective and environmentally friendly growing technologies. The data on the composition and structure of production costs and the cost of growing planting material of forest berry plants of the genus Vaccinium in in vitro culture and under production conditions (in terms of 1 ha of plantation area) are presented. The economic efficiency of production (profitability - 187.7-475.4 %) using the method of clonal micropropagation in obtaining planting material of forest berry plants of the genus Vaccinium for industrial cultivation at enterprises is shown.

Для выявления последовательности разрушения древесины и определения организмов, способных выступать в качестве биоиндикаторов, обследованы 65 модельных деревьев ели европейской в зоне хвойно-широколиственных лесов Московской обл. Разработан метод исследования модельного дерева, позволяющий получить данные, характеризующие степень разрушения древесины в результате влияния биологических и абиотических факторов. Предложена шкала стадий разрушения древесины ели под воздействием ксилотрофных базидиомицетов и сапроксильных насекомых. На основе показателей модельных деревьев выделены биоиндикаторы стадий биодеструкции и последовательность их смены в зависимости от состояния древесного субстрата. Сделан вывод о том, что ксилолиз является единым динамическим процессом, происходящим под воздействием комплексов мико- и зоодеструкторов. При этом определить биоиндикаторы можно только для 1–4-й стадий разрушения древесины. Для 5-й стадии характерна бурая мягкая гниль с уровнем разложения древесины более 80 %, что делает выявление биоиндикаторов ксилолиза в полевых условиях невозможным.
The process of natural destruction of wood combines two lines of decomposition of wood matter: mycogenic destruction of wood, which occurs under the influence of xylotrophs and mechanical destruction of the structure of wood matter during the vital activity of xylobionts. To identify the sequence of destruction and identify organisms capable of acting as bioindicators, 65 model trees of European spruce in the zone of coniferous-deciduous forests of the Moscow region were examined. To conduct the study, a method for studying a model tree has been developed that allows to obtain integrated data on the destruction of wood under the influence of biological and abiotic factors. A scale of stages of the destruction of spruce wood under the influence of xylotrophic basidiomycetes and saproxyl insects is proposed. Based on data from model trees, bionditactors of biodestruction stages and the sequence of their change depending on the state of the wood substrate are identified. It is concluded that xylolysis is a single dynamic process that takes place under the influence of complexes of mycodestructors and zoodestructors. Determination of bioindicators is possible for 1–4 stages of destruction of wood. Stage 5 is characterized by brown soft rot with a wood decomposition level of more than 80 %, which makes it almost impossible to identify biological indicators of xylolysis in the field.

Проанализирована динамика смены пород в тополевой полезащитной лесной полосе, произрастающей рядом с лесными культурами сосны обыкновенной, в условиях Республики Башкортостан. В лесной полосе появился благонадежный подрост сосны, подрост тополя ни на одной учетной площадке не обнаружен. Характеристика подроста сосны (густота, средние возраст, высота, диаметр) и состояние деревьев тополя изучены в 2008 и 2020 г. Выявлено, что произошла смена конструкции лесной полосы с ажурной на плотную, наблюдается частичное усыхание тополя, на некоторых участках отмечается выход подроста сосны в первый ярус. В процессе учетов 2008 и 2020 г. наибольшая густота подроста сосны (свыше 1,5 тыс. шт./га) установлена на расстоянии до 200 м от лесных культур сосны, наименьшая густота (не более 0,4 тыс. шт./га) – в центре лесной полосы. В 2020 г. мелкий подрост не обнаружен, преобладал крупный подрост, часть из которого вступила в репродуктивную фазу. Аналогичная картина наблюдается и в соседних лесных полосах, что позволяет сделать выводы о возможности смены пород в полезащитных лесных полосах, которая должна сопровождаться проведением рубок ухода.
The dynamics of the change of rocks in the poplar protective forest belt growing next to the forest crops of the Scotch pine is analyzed. A forest belt 450 m long and 10 m wide grows near the village of Shigaikulbash in the Buzdyaksky district of the Republic of Bashkortostan. Accounting sites are laid every 50 m. Reliable pine undergrowth grows in the forest belt, poplar undergrowth was not found on any of the accounting areas. Characteristics of pine undergrowth (density, average age, height, diameter) and the condition of poplar trees were compared for 2008 and 2020. It was revealed that there was a change in the design of the forest belt from openwork to dense, there is a partial shrinkage of poplar, in some areas there is an exit of pine undergrowth to the first tier. For both periods, the highest density of pine (over 1.5 thousand units/ha) was detected at a distance of up to 200 meters from pine forest crops, the lowest density (no more than 0.4 thousand units/ha) – in the center of the forest belt. In 2020, the category of small undergrowth was not found, most of it is large undergrowth, some of which have entered the reproductive phase. A similar pattern is observed in neighboring forest belts, which allows us to draw conclusions about the possibility of changing the species of protective forest strips, which should be accompanied by logging.

Оптимизированный метод оценки позволяет разрабатывать рекомендации по проведению специаль­ных мероприятий, повышающих биологическую устойчивость радиоактивно загрязненных насаждений, с целью возвращения обследованных участков в хозяйственный оборот.
The article is devoted a method for assessing the biological stability of pine plantations using the fluctuating asymmetry index (IFA) with automatic processing of scanned images of needles. This method makes it possible to eliminate errors associated with the influence of the human factor in order to obtain up-to-date data on the assessment of disturbances in the development of woody plants for the purpose of early diagnosis of a decrease in the biological stability of forest ecosystems. Aspects of the bioindicative assessment of disturbances in the stability of plant development based on morphometric traits using the index of fluctuating asymmetry and criticism of this method are considered. The results of a bioindicative evaluation of disturbances in the developmental stability of Scots pine under conditions of radioactive contamination are presented, taking into account the shortcomings of the method. To eliminate system errors associated with the influence of the human factor, digital images of pine needles were processed in a semi-automatic mode. At the end of the article, recommendations are given for carrying out special measures that increase the biological stability of plantations in order to return the surveyed areas to economic circulation.

Одним из ключевых направлений обеспечения безопасности природных экосистем и разработки эффективных пожарно-профилактических мероприятий является понимание природы возникновения лесных пожаров. При установлении закономерностей влияния природных и антропогенных факторов на возгорание растительности могут быть усовершенствованы способы и методы охраны лесов от пожаров, что особенно актуально в условиях глобального потепления климата. В работе представлены результаты экспериментальных исследований процесса воспламенения наземного лесного горючего материала в виде мха, травы, опада листвы, еловой и сосновой хвои, мелких веток, коры под воздействием солнечного излучения, сфокусированного стеклянной тарой. Установлено, что способность к воспламенению под воздействием сфокусированного теплового потока из исследуемых материалов проявляют мох, трава и опад листвы либо живой напочвенный покров с их преобладанием в составе. К возникновению горения могут привести оставленные в лесу стеклянные банки вместимостью 1 л и более, наполненные водой или другой прозрачной жидкостью. Пустые стеклянные банки вместимостью от 0,5 до 10 л, пустые и наполненные жидкостью бутылки вместимостью от 0,33 до 1 л, а также осколки стекла от указанной тары не способны сфокусировать поток солнечного излучения до величины, достаточной для воспламенения напочвенного покрова влажностью 10–30 %.
One of the key areas for ensuring the safety of natural ecosystems and developing effective fire prevention measures is understanding the nature of forest fires. By establishing the patterns of influence of natural and anthropogenic factors on the burning of vegetation, the ways and methods of protecting forests from fires can be improved, which is especially important under conditions of global warming. The paper presents the results of experimental studies of the process of ignition of ground forest combustible material in the form of moss, grass, leaf litter, spruce and pine needles, small branches, and bark by solar radiation focused by glass containers. It has been established that from the materials under study, moss, grass and leaf litter, or ground cover with their predominance in composition exhibit the ability to ignite under the influence of a focused heat flux. Glass jars with a capacity of 1 liter or more filled with water or other transparent liquid left in the forest can cause fire. Empty glass jars with a capacity of 0.5 to 10 liters, empty and liquid-filled bottles with a capacity of 0.33 to 1 liter, as well as glass fragments from the said containers are not capable of focusing the flux of solar radiation to a value sufficient to ignite the ground cover with a humidity of 10–30 %.

Abstract

OBJECTIVE
To investigate the effect of intranasal (IN) flunixin meglumine (FM) and intra-inguinal (IG) lidocaine on castration inflammation using prostaglandin E2 (PGE2) concentration as a biomarker.

METHODS
This randomized controlled trial was conducted in March 2022. Blood was collected at −24, 1, and 24 hours postcastration for PGE2 quantification from 195 piglets that received 1 of 8 treatments: (1) saline (1.5 mL) applied IG and IN (0.2 mL) followed by surgical castration (n = 24); (2) saline (1.5 mL) IG and IN (0.2 mL) followed by sham castration (25); (3) lidocaine (20 mg/kg or 1.5 mL) IG followed by surgical castration (24); (4) lidocaine (20 mg/kg or 1.5 mL) IG followed by sham castration (25); (5) FM (2.2 mg/kg) IN followed by surgical castration (25); (6) FM (2.2 mg/kg) IN followed by sham castration (24); (7) lidocaine (20 mg/kg or 1.5 mL) IG and FM (2.2 mg/kg) IN followed by surgical castration (24); and (8) lidocaine (20 mg/kg or 1.5 mL) IG and FM (2.2 mg/kg) IN followed by sham castration (24).

RESULTS
Prostaglandin E2 concentrations did not increase following the castration procedure and were not an effective biomarker of castration inflammation. Piglets that received lidocaine demonstrated no difference in PGE2 levels across all time points. Piglets administered FM had lower PGE2 concentrations at 1 hour and 20 minutes postdrug administration in both the sham and castrated piglets.

CONCLUSIONS
Prostaglandin E2 was not an effective biomarker to quantify castration inflammation. Flunixin meglumine was able to reduce PGE2 concentration in piglets regardless of castration procedure, but lidocaine had no impact. Decreased PGE2 levels in FM-treated pigs are likely associated with the drug’s ability to mitigate a noncastration-associated inflammatory process occurring independent of the castration procedure.

CLINICAL RELEVANCE
Flunixin meglumine reduced circulating PGE2 concentration in the blood, regardless of the castration procedure, indicating a potential for the drug to mitigate an inflammatory process unrelated to castration.
A review of the current standing of microRNA expression in canine urothelial carcinoma

Published: July 2024

Abstract
Urothelial carcinoma (UC) is the most common urogenital cancer in dogs. With early diagnosis, the disease can be controlled, to reduce progression of disease, in most dogs with a good quality of life. MicroRNAs (miRNAs) have been identified as a potential diagnostic and prognostic tool due to their stability and presence in both bodily fluids and tissues. MiRNAs have been frequently researched in human medicine and human UC; however, few manuscripts regarding miRNAs in canine UC are available. A search was performed on both PubMed and Google Scholar evaluating original research manuscripts with experimentally validated results for the terms “canine” or “dog”; “urothelial carcinoma,” “bladder cancer,” “transitional cell carcinoma,” “TCC,” “MIBC,” “IMBUC,” or “BLCA”; and “miRNA” or “microRNA.” We identified 3 peer-reviewed manuscripts evaluating miRNA expression in canine UC and compared the reported miRNA expression studies to human UC to identify experimentally validated targets of the dysregulated miRNA. In this review, we highlight the similarities and differences between what is reported in canine UC and human UC and discuss the literature gaps that call for further evaluation.

Abstract
Classroom teaching mode is an important factor affecting classroom quality and students’ performance. The use of science and technology combined with advanced teaching concepts to rationalize classroom teaching innovation and change has become a research hotspot in the field of education. In this paper, we use the BOPPPS teaching mode on the basis of big data technology to promote teaching innovation in the existing classroom teaching chemical principles. Using a questionnaire survey to study the teaching status of chemical principles in a city university, it is found that the current chemical principle classroom teaching is generally characterized by the problems of solidified teaching mode design, single teaching evaluation method, random design of teaching objectives, etc. The BOPPPS model is applied to the teaching of chemical principles at a city university. The BOPPPS model is applied to the teaching practice of chemical principles in a university, and the student’s classroom performance before and after the change of teaching mode shows obvious differences. After the experiment, 64.17% of the students expressed hope that the BOPPPS teaching model could be promoted in other disciplines. Cluster analysis of students’ performance before and after the experiment using an optimized K-means clustering algorithm shows that the performance of the seven students extracted from the experiment significant improvement after the experiment. The use of the BOPPPS teaching mode makes the students’ score range increase from 60-70 before the test to 80-90 after the test.
Study on the enhancement of dielectric properties of epoxy resin composites by fullerene doping
Authors: Zhang Zaizhen , Zhang Yuanyuan , Liu Hongchang 
Published: July 2024

Abstract
Based on the fact that C60 is one of the most abundant and readily available molecular configurations in the fullerene family, this paper investigates the effect of doping fullerenes on the dielectric properties of epoxy composites using C60 as a representative. The structure and properties of fullerene molecules are thoroughly examined from the point of view of materials chemistry. The equipment required for the experiment is selected, the experimental sample preparation plan is formulated, and the structure and dielectric properties of the prepared samples are analyzed by corresponding data analysis. The results show that in the range of r less than 1.03 Å, the particle distribution probability of the fullerene-doped epoxy composites in this interval is 0. As r continues to increase, the probability density of the fused C60 epoxy composites is higher than that of the epoxy matrix. The frequency band of 1 MHz has an enhancement of 0.053 and 0.043. However, the dielectric constant of the composite epoxy resin in the high-frequency interval gradually falls back with the increase of filler, while the enhancement of the dielectric constant occurs in the low-frequency interval, and the fullerene is also optimized in terms of the dielectric constant and dielectric loss properties. Fullerene’s excellent dielectric properties have been confirmed by this study, which is important to broaden the epoxy resin market and improve the competitiveness of products.

Abstract
With the deepening of the reform of civic education in colleges and universities, the traditional mode of civic education has gradually revealed its limitations. The integration of red cultural resources into the ideological education of colleges and universities has become a more common method of ideological education. According to the attributes of red cultural resources in civic education, the study combines the HMM model, BiLSTM model, and BiLSTM-CRF model to construct a red cultural resource base for civic education courses in colleges and universities so as to dynamically integrate red cultural resources in civic education in colleges and universities, analyze the textual features of the red cultural resources in the research methods in the college and university education resource base, and explore the teaching of civic education in colleges and universities. The top five high-frequency words in the mainstream research methods are “history” (540), “comparison” (538), “literature” (486), “system” (334), “discipline” (245), and the most frequent words in the empirical research method are “case” (67), “investigation “(26), “interview” (23), “culture” (15), and “qualitative research” (18). The degree of understanding of the content of Yan’an red cultural resources by students of colleges and universities in Shaanxi Province is Yan’an spirit (14.65%), celebrity heroes’ deeds (26.19%), red literary writings (3.59%), red attractions (35.95%), the course of the revolutionary struggle (25.16%), deeds of poverty alleviation (19.54%), and no understanding (8.57%).
