При исследовании гармонических волн вводится понятие фазовой скорости как скорости изменения состояния среды, при этом фазовая скорость выражается через частоты собственных колебаний и поэтому исследование распространения гармонических волн имеет прямое отношение к проблемам определения собственных форм и частот колебание ограниченных в плане плоских элементов. В работе рассматривается ряд задач колебания плоских прямоугольных элементов при произвольных граничных условиях по краям элемента с целью определения частот собственных колебаний и рассматривается некоторые задачи о распространении гармонических волн при различных свойствах материала. В зависимости от рассматриваемых частных видов плоского элемента в общих решениях трехмерной задачи выбираются основные неизвестные функции: перемещения или деформации в точках фиксированной плоскости плоского элемента, в частности, в срединной плоскости пластинки постоянной толщины. Перемещения и напряжения в произвольной точке плоского элемента выражаются через основные неизвестные функции, которые определяются из граничных условий на поверхностях плоского элемента. Общее решение относится к уравнению гиперболического типа, которое и описывает колебательный и волновой процесс в плоском элементе. Ограничиваясь в рядах общего уравнения конечным числом первых слагаемых, получаем приближенные уравнения колебания того или иного плоского элемента. Далее в работе рассматривается ряд задач колебания плоских прямоугольных элементов при произвольных граничных условиях по краям элемента с целью определения частот собственных колебаний методом Бленда и Филиппова. Этот метод приближённый позволяет находить частоты собственных колебаний плоских элементов. Задачи для вязкоупругого материала плоского элемента решаются аналогично. Изложили постановку метода на случай плоского элемента, когда материал элемента упругий. В дальнейшем метод будем применяться и для элементов из вязкоупругого материала.

Universal access to safe drinking water is not only a fundamental need but also a basic human right. Water reuse and rainwater harvesting systems provide essential technical alternatives for water supply management. There are several alternative water sources available for reuse after some needed treatment: rainwater, stormwater, greywater, drainage water etc. The integration of on-site non-potable water reuse enhances the environmental goals of a green building by lowering the consumption of potable water and decreasing the volume of storm-water and wastewater that must be sent to the City's Wastewater Treatment Plants for treatment. The purpose of the article is to analyze two approaches for partially replacing tap water (rainwater harvesting and treated greywater reuse), to compare the constructive characteristics of these systems and calculate annual volume the potential water savings in Ukraine's residential areas using each option. Both methods offer sustainable solutions to alleviate water scarcity but differ significantly in construction, application, and operational mechanisms. For a comparative analysis of the two indicated alternative sources, are present the constructive features of water supply in the context of rainwater collection and use, and greywater. The volume of greywater generated in low-rise residential areas and rainwater that can be harvested from roofs was counted using Ukranian normative documents. The result shows at a building density of 0.4, the greywater volume is 1.45 times greater than that of rainwater; at a density of 0.54, it is 1.49 times greater under Ukraine's maximum annual precipitation of 750 mm. With comprehensive water recycling systems, it is possible to reduce freshwater demand by approximately 30% through greywater reuse and by around 10% with rainwater harvesting. These savings offer both economic and environmental benefits, making water recycling especially advantageous for water-scarce regions seeking to mitigate the impacts of climate change.

ObjectiveMyocardial protection is important for a successful procedure cardiac surgery, and the key element of myocardial protection is cardioplegia. We compared Del Nido cardioplegia (DN) and Bretschneider histidine-tryptophan-ketoglutarate cardioplegia (HTK) regarding cardioprotective effects in a porcine model of prolonged ischaemia.MethodsLandrace pigs weighing 50–60 kg were randomized to receive either DN (n = 9) or HTK (n = 9). All pigs underwent cardiac arrest for 90 min followed by 120 min of reperfusion/convalescence. A detailed set of laboratory, histological and functional parameters was acquired at baseline, during cardiac arrest and following reperfusion/convalescence.ResultsPressure-volume measurements revealed better systolic and diastolic left ventricular performance in DN as compared to HTK (both p &lt; 0.05). Haemoglobin decreased after application of the cardioplegic solution. The decrease was more pronounced in the HTK group than in the DN group (p &lt; 0.01). In contrast to DN, sodium (p &lt; 0.01) and chloride levels (p &lt; 0.05) were significantly decreased in the HTK group after initiation of CPB and remained decreased after reperfusion. The number of animals requiring defibrillations to restore sinus rhythm significantly differed between the groups [HTK: 100% (n = 9/9) vs. DN: 44.4% (n = 4/9), p = 0.03]. Expression of ICAM-1 as a marker of endothelial dysfunction was lower in the DN group compared to the HTK group (p = 0.02). Histological evaluation, oxidative and nitrosative stress, mitochondrial membrane integrity and apoptosis markers were comparable between DN and HTK groups (all p &gt; 0.05).ConclusionsIn this porcine model with prolonged ischaemia, DN was superior to HTK in terms of haemoglobin levels, blood electrolytes, spontaneous return of sinus rhythm, left ventricular function, and endothelial injury. Histomorphological parameters indicative of ischaemia/reperfusion injury, oxidative stress and mitochondrial function as well as apoptosis-inducing factors did not differ.

ObjectiveThe left atrial stiffness index (LASI) holds significance in the atrioventricular coupling function and heart failure progression. To assess left atrial function and evaluate the relationship between LASI and exercise capacity in hypertension-related heart failure with preserved ejection fraction (HT-HFpEF).MethodsThe study involved 62 healthy subjects and 163 patients with HT (112 patients in simple HT group and 51 patients in HT-HFpEF group). Each patient performed exercise stress test and standard ultrasonic images were evaluated. A comprehensive evaluation of atrioventricular function, along with investigation into the correlation between these functional parameters and exercise capacity. And further to investigate the feasibility of predicting exercise intolerance using three-dimensional derived left atrial strain index (LASI) (E/e'/LASr and E/e'/LASr-c).ResultsCompared to healthy subjects, HT group demonstrated the elevation in left atrial volume accompanied by decrease in strain value (P &lt; 0.05). In HT-HFpEF group, further significant reductions were observed in both longitudinal (LASr) and circumferential strain (LASr-c, LASct-c) (P &lt; 0.05). Univariate regression demonstrated that both E/e'/LASr and E/e'/LASr-c were significantly correlated with metabolic equivalents (METs) (r = −0.462, P &lt; 0.001; r = −0.381, P &lt; 0.001). The E/e'/LASr demonstrates comparable diagnostic efficacy to exercise-E/e' in assessing exercise intolerance in HT-HFpEF patients (AUC: 0.836 vs. 0.867, P = 0.239).ConclusionProgressive LA remodeling contributes to decreased atrioventricular compliance in HT and HT-HFpEF patients.E/e'/LASr serves as an independent indicator of exercise intolerance in patients with HT-HFpEF.

IntroductionAlthough adaptive instruction has become increasingly important as a component of effective instruction, the mechanism of adaptive instruction remains underexplored. This study examined the potential associations between school climate and teacher emotions on adaptive instruction.MethodsThis study used cross-sectional approach with a sample included 2,880 primary school teachers from Chongqing, China.ResultsThe results indicated that of the five dimensions of school climate examined, teacher collaboration, student relations, and instructional innovation had positive and significant associations with adaptive instruction. Regarding teachers’ emotions, enjoyment was positively while anxiety was negatively associated with teachers’ adaptive instruction.DiscussionAs teachers’ positive emotions play important roles in adaptive instruction, policymakers and educators should focus on fostering teachers’ experiences of positive emotions. The finding of an adverse role of a teacher’s negative emotion in shaping adaptive instruction may be used in intervention programs and pieces of training for both pre-service and in-service teachers.

IntroductionRegional carbon storage is a significant indicator of ecosystem service functions. Examining the impact of changes in land use on carbon stock in the Chang-Zhu-Tan urban agglomeration under different topographic reliefs is paramount for sustainable land resource utilization and realizing carbon peaking and neutrality goals.MethodsThis study focuses on the Chang-Zhu-Tan urban agglomeration, using the InVEST model in combination with land use data to explore the distribution pattern of land use change and carbon storage from the perspective of topographic relief.ResultsThe research results show that:(1) the optimal analysis window for topographic reliefs in the study area is 17 × 17, covering an area of 0.26 km², with an average topographic relief of 78.58 m. (2) Between 2000 and 2020, Cultivated land and forest land decreased by 592.27 km² and 421.5 km², respectively, while the built-up land area increased by 982.36 km². (3) Due to human activities, carbon stock in the study area showed a decreasing trend, with a total reduction of 13.37 × 106 tons over the past 20 years. (4) The distribution of carbon stock across topographic reliefs mainly exhibits low-value and moderate-value carbon stock concentrations in flat and slightly undulating areas. In contrast, moderately high-value and high-value carbon stock concentrations are concentrated in gently and moderately undulating areas.DiscussionThese research findings provide a scientific foundation for optimizing the spatial pattern of the study area and formulating carbon peak and carbon-neutral policies.

IntroductionThe coronavirus disease 2019 (COVID-19) global pandemic has been the most severe public health emergency since 2019. Currently, the Omicron variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been the most dominant. The most prominent symptom of SARS-CoV-2 infection is respiratory. Meanwhile, the fatality of COVID-19 was mainly from pneumonia. However ,in patients with SARS-CoV-2 infection who have pneumonia and those who do not, the differences in the immune repertoire still require further investigation.MethodsWe conducted seven-chain adaptome immune repertoire analyses on patients with SARS-CoV-2 Omicron infection, both with and without pulmonary infiltration.ResultsPatients with pulmonary infiltration exhibit lymphopenia, a decreased proportion of the overall TCR repertoire alongside an increased BCR repertoire, reduced IGHD and IGHM isotype expression, a shorter mean CDR3 length for TRG, and a longer mean length for TRD, as well as diminished clonality and diversity in the TCR/BCR repertoire. Meanwhile, patients with pulmonary infiltration have distinct V-J gene usage and unique CDR3 signature, as well as BCR class switch recombination pattern. Finally, prior vaccination triggered less BCR IGHM/IGHD somatic hypermutation response, preserved the diversity of the entire adaptive immune repertoire, and provided clinical protection against severe or critical conditions following Omicron infection.DiscussionWe report a unique, comprehensive adaptive immune system signature in patients with pulmonary infiltration, which may serve as potential immunological biomarkers and therapeutic targets.
Leveraging single-cell and multi-omics approaches to identify MTOR-centered deubiquitination signatures in esophageal cancer therapy
Authors: Tian Kang , Yao Ziang , Pan Da 
Published: December 2024

BackgroundEsophageal squamous cell carcinoma (ESCC) remains a significant challenge in oncology due to its aggressive nature and heterogeneity. As one of the deadliest malignancies, ESCC research lags behind other cancer types. The balance between ubiquitination and deubiquitination processes plays a crucial role in cellular functions, with its disruption linked to various diseases, including cancer.MethodsOur study utilized diverse analytical approaches, encompassing Cox regression models, single-cell RNA sequencing, intercellular communication analysis, and Gene Ontology enrichment. We also conducted mutation profiling and explored potential immunotherapeutic agents. Furthermore, in vitro cellular experiments and in vivo mouse models were performed to validate findings. These methodologies aimed to establish deubiquitination-related gene signatures (DRGS) for predicting ESCC patient outcomes and response to immunotherapy.ResultsBy integrating datasets from TCGA-ESCC and GSE53624, we developed a DRGS model based on 14 deubiquitination-related genes (DUBGs). This signature effectively forecasts ESCC prognosis, drug responsiveness, and immune cell infiltration patterns. It also influences the mutational landscape of patients. Those classified as high-risk exhibited reduced survival rates, increased genetic alterations, and more complex cellular interactions, potentially explaining their poor outcomes. Notably, in vitro and in vivo experiments identified MTOR, a key component of the signature, as a promising therapeutic target for ESCC treatment.ConclusionOur research highlights the significance of 14 DUBGs in ESCC progression. The risk score derived from this gene set enables clinical stratification of patients into distinct prognostic groups. Moreover, MTOR emerges as a potential target for personalized ESCC therapy, offering new avenues for treatment strategies.
