Authors: Соколов Н.С.
Published: April 2024

В статье рассматривается проблема строительства высокоскоростной магистрали в долине рек Волга, Ока, Сура на основаниях со сложными инженерно-геологическими условиями с перемеживающимися слабыми грунтами (просадочные, биогенные представленные илами, торфами и сапропелями, набухающие и т.д.). Наличие в основании сильно деформируемых инженерно-геологических элементов усложняет безопасную эксплуатацию скоростных поездов. Предельно допустимая осадка земляного полотна при скоростях движения до 400 км/ч не должна превышать Su = 15 мм. Для обеспечения требований безопасной эксплуатации подвижного состава высокоскоростных магистралей (ВСМ) требуется армирование слабых оснований с передачей внешних нагрузок на инженерно-геологические элементы с высокой несущей способностью и низкой деформативностью.

Authors: Ninghardjanti‬ Patni , Rusmana Dede , Subarno Anton , Winarno  , Wirawan Arif Wahyu
Published: April 2024

The study addresses the crucial yet under-researched analytical and planning skills of pre-service college administrators (APsCA) necessary for effective educational leadership. It pioneers by developing a situational judgment test (SJT) to evaluate these skills, given the absence of suitable assessment tools. Focusing on three constructs—cause/goal analysis, constraint analysis, and planning—the research utilizes exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), along with Fornell's discriminant validity test, to establish and confirm the psychometric properties of the SJT. Through regression and correlation analyses, it assesses the impact of demographic and academic variables on APsCA, particularly highlighting the different effects in urban versus rural environments. The EFA and CFA results with factor loadings above 0.30 and the average variance extracted (AVE) over 0.50 confirm the test's validity. Significant findings reveal a strong influence of urban settings in enhancing APsCA, underscored by a statistical significance of p < 0.05. Administrators' capabilities in cause/goal analysis are predominantly high, whereas constraint analysis varies, and planning skills need bolstering. Overall, the APsCA levels are classified as high to very high, suggesting a promising baseline for future educational leaders but also indicating specific areas for targeted skill development.

The main reasons that make mankind look for new sources of energy are decreasing dependence on fossil fuels and reducing pollution. Wastewater treatment with the help of microbial fuel cells is an area where these two goals can be combined. Microbial fuel cells, in which microorganisms catalyze the oxidation of organic substances, represent a new and promising alternative for electricity generation. The creation of an efficient cathode in such systems is the important problem. It is evident that in these applications an oxygen (air) electrode is a promising cathode. In this study, the oxygen biocathode based on the laccase enzyme Pleurotus ostreatus HK-35 was developed and its electrochemical properties were studied depending on the immobilization method of the enzyme on the surface of a carbon-graphite electrode and the type of the electrolyte. It was experimentally established that laccase injection using a sol-gel matrix was the effective method for immobilizing laccase on the surface of a carbon-graphite electrode. It was shown that the more efficient operation of the laccase-based biocathode was observed in a phosphate-citrate (pH 4.0) buffer solution, i.e., in an acidic environment.

This article discussessome aspects of the methodology for preparingsludge andcoresamples for lithological and petrophysicalstudies. Methods for obtainingrockmaterial(sludge,core) are described interms of determiningthemoment of openingthereservoir layer,tyingthecore in depth, and sampling the sludge. A sludge collector has been proposed that makes it possible to obtain sludge of overall fractions washed from the drilling fluid. The effectiveness of the harmonic analysis method, which takes into account the lithology of the studied section and changes in drilling parameters to optimize the frequency of sludge sampling during drilling, is shown. A system for placing sludge sampling points has been justified to increase the information content of the study of well sections. An analysis of the actual material on the connection of sludge to formations using natural gamma activity in wells drilled in the conditions of the Saratov Volga region was carried out. The distribution of the residual values of the burial depths according to thesludge and well logging allowed us toconclude that in the vast majority (> 75%) ofcases, the binding ofsludge during geological testing iscarried out withsatisfactory accuracy. The implementation ofsome elements of the above described interpretation techniques is shown using the example of one of the wells located in the northwestern part of the near-shore zone of the Caspian basin.

Znaczna część gazu ziemnego w Polsce jest zaazotowana oraz zawiera dwutlenek węgla, co niejednokrotnie rodzi problemy z jego zagospodarowaniem. Tymczasem nawet niewielkie zmniejszenie zawartości azotu i CO2 w gazie wpływa na zwiększenie jego wartości energetycznych jako produktu handlowego. Celem pracy było zbadanie możliwości usunięcia części niepalnych składników z gazu ziemnego i gazu towarzyszącego wydobywanej ropie naftowej. Wiąże się to z jednoczesnym podwyższeniem ich jakości i kaloryczności. Można to uzyskać z wykorzystaniem separacyjnej technologii membranowej zastosowanej w najkorzystniejszych warunkach prowadzenia takiego procesu. Otrzymywany w ten sposób główny wysokociśnieniowy strumień gazu wzbogaconego (np. około 85% obj. strumienia gazu surowego) stanowiłby produkt handlowy. Niskociśnieniowy strumień gazu zubożonego (pozostałe 15% obj.) można wykorzystać na potrzeby własne kopalni gazu ziemnego. W ramach pracy dokonano przeglądu literatury w zakresie charakterystyki gazu ziemnego oraz separacji składników na membranach. Opracowano projekt instalacji, dobrano i skalibrowano przyrządy pomiarowe oraz utworzono stanowisko badawcze membranowego rozdziału gazów z wykorzystaniem membran poliimidowych. Wytworzono mieszanki gazowe na bazie rzeczywistego gazu ziemnego, które zawierały od 7% do 90% azotu oraz od 0,2% do 6% dwutlenku węgla. Przeprowadzono testy ich separacji na membranach w tanim jednostopniowym układzie pod kątem wydzielenia z gazu ziemnego części dwutlenku węgla i azotu. Badania na membranach były prowadzone w funkcji współczynnika podziału związanego ściśle ze stosunkiem ilości wysokociśnieniowego strumienia gazu wzbogaconego do gazu wlotowego. W artykule dokonano również porównania zmian wartości energetycznej (liczby Wobbego i wartości opałowej) uzyskiwanych produktów w stosunku do surowego gazu wlotowego. Badania usuwania dwutlenku węgla z gazu mogą mieć istotne znaczenie, gdyby doszło do znacznego wzrostu ilości tego składnika w strefie gazowej złoża podczas procesów intensyfikacyjnych.
Mikroinstalacje wiatrowe źródłem energii odnawialnej dla indywidualnych gospodarstw domowych
Authors:   Instytut Nafty i Gazu – Państwowy Instytut Badawczy, Ciechanowska Maria
Published: April 2024

W artykule przedstawiono mikroinstalacje wiatrowe jako źródło pozyskiwania alternatywnej energii z wiatru przeznaczone dla indywidualnych gospodarstw domowych oddalonych od sieci elektroenergetycznej. Instalacje te mogą stanowić główne źródło zasilania w zależności od wielkości zapotrzebowania na energię lub pełnić funkcję źródła wspomagającego inny typ zasilania, np. fotowoltaiczny. Omówiono mikroinstalacje OZE (o mocy zainstalowanej elektrycznej <50 kW), które w roku 2022 dostarczyły w kraju energii o mocy ponad 9,3 GW. Z około 1,2 mln mikroinstalacji zarejestrowanych i podłączonych do sieci ponad 99% stanowiły mikroinstalacje fotowoltaiczne. A zatem energia pozyskana z wiatru dzięki zastosowaniu mikroinstalacji ma na obecnym etapie minimalny udział w bilansie energetycznym OZE. Przedstawiono charakterystyki mikroinstalacji wiatrowej i obowiązki wynikające z zamierzenia budowlanego w świetle przygotowywanych zmian wprowadzanych poprzez nowelizację prawa budowlanego i ustawy o odnawialnych źródłach energii. Zaprezentowano konstrukcję mikroinstalacji wiatrowej, zwracając uwagę na dobór mocy turbiny wiatrowej – uzależniony od zapotrzebowania na przyłączeniową moc elektryczną – jak i na warunki wietrzne panujące w danym regionie. Wskazano na bardzo duże zainteresowanie europejską inicjatywą obywatelską w zakresie łącznego zastosowania mikroinstalacji fotowoltaicznej i wiatrowej w każdym gospodarstwie UE. Takie przedsięwzięcie stanowiłoby podstawę tzw. zielonej europejskiej unii energetycznej. Deklaracje poparcia inicjatywy podpisało 27 krajów członkowskich Unii, niemniej na obecnym etapie wniosek wycofano z dalszego procedowania ze względów formalnych. Być może powróci on do realizacji w innej formie.
Идеология космополитизма в современном информационном обществе (в печати)
Authors: Терлецкий В.А.
Published: April 2024

Актуальность. В работе рассмотрен феномен космополитизма в современном мире. В статье представлены работы различных теоретиков, политических философов для разработки авторской терминологии  каждой из этих концепций и интегрирования субъективистского подхода в эти обозначения. Современные исследователи по-разному подходят к теории космополитизма и идее реализации всемирного гражданства, это приводит к актуализации самой темы. А в связи с тем, что тема космополитизма полемична, поиск оснований, природы, статуса космополитической идеи, ее интерпретации, становится на данный момент главной задачей сторонников всеобщего гражданства, в то время как цель критиков представленной теории заключается в последовательном критическом анализе современных проектов и самой идеи всемирного гражданского состояния. Цель статьи – выявить специфику идеологии «космополитизм» и критические характеристики утопической идеи «мирового гражданства». Объектом исследования является представленность политических идеологий. В соответствии с объектом исследования был определён предмет исследования –  специфика процесса возникновения и развития идей космополитизма. Результаты: доказано, что современное информационное общество создано для реализации концепции космополитизма и мирового гражданства. В современном мире благодаря глобализации стираются грани между этнической, конфессиональной и культурной самоидентичностью. Появляются предпосылки нового гражданства – мирового. Выводы: выявлены два наиболее явных отрицательных аспекта космополитизма, которые придают идеологии утопический замысел: во-первых, потеря индивидуализма и идентичности; во-вторых, ослабление национальных и культурных особенностей конкретного государства, которые веками складывались на данной территории, приверженцы патриотизма относятся к космополитическим идеям негативно, полагая, что они подрывают их ценности.
Структурно-функциональный анализ православной общины как традиционного общества в современных условиях (в печати)
Authors: Атаманов А.В.
Published: April 2024

В статье проведен социально-философский анализ православной религиозной общины как традиционного общества в современных условиях. В настоящее время российское общество представляет собой сложную структурированную систему, представленную различными группами традиционной, религиозной, индустриальной и постиндустриальной культуры. Достаточно широкое распространение имеют религиозные структуры Русской Православной Церкви, представленные юридически чаще всего как Местная религиозная организация Православный Приход Русской Православной Церкви (Московский Патриархат). Целью статьи является анализ и осмысление функций структурных компонентов данного общества заложенных его Уставом. В исследовании социальной системы приходской общины применяется структурно-функциональный подход Р. Мертона и юнгианское понимание архетипа как поведенческой модели. Выделены следующие структурные акторы приходской общины: храм, клир, причт, прихожане, воскресная школа, богадельня, братство, кладбище, приходская больница и подобные приходские организации. Каждый структурный элемент прихода характеризуется своим функционалом. Описанные функции структурных компонентов изучаемого общества сгруппированы по основным критериям, которые отражают цели и задачи существования данного социума, такие как морально-этические, религиозно-мировоззренческие, культурно-просветительские, социально-политические и системообразующие. Анализ основных моделей поведения акторов прихода выявил некоторые противоречия в структурных связях общины, что позволит при дальнейшем изучении  данного феномена определить пути его развития и трансформации. Отмечен возрастающий интерес к религиозным общинам с присущими им глубокими историческими и социальными предпосылками. Формат современного православной общины является малопривлекательным, поскольку имеет недостатки управленческий структуры, приводящие к формализации различных сфер деятельности. Следствием чего является трансформация религиозных функций и отсутсвие горизонтальных социальных связей.

Algumas mães, contudo, não são capazes de identificar esses indicadores, cabendo ao profissional de saúde, a responsabilidade de avaliar e informar o estado de saúde/doença às mães.
Conclusão: Essa percepção da mãe no reconhecimento da condição de saúde de seus filhos otimiza a busca pelo tratamento adequado, o que pode favorecer o tempo para o manejo clínico adequado. Esse atributo é desejável nas comunidades quilombolas do estudo, devido às condições de acesso aos serviços de saúde.
Balance of work and personal life in the perception of civil servants of the metropolitan megalopolis
Authors: Pinchuk Antonina , Tikhomirov Dmitry , Kulikova Anna
Published: April 2024

The article presents the results of a sociological study to identify the peculiarities of the perception of work-life balance by modern civil servants of the metropolitan megalopolis. As the empirical basis the materials of questionnaires and interviewing carried out by the authors in 2022 in several ministries of the city of Moscow were used. Using modern methods of textual data analysis, the authors visualise with the help of a word cloud the answers of respondents to an open-ended question about their subjective understanding of work-life balance. Such terms as "time", "opportunity" and "family" prevail in the interpretation of the interviewed civil servants, that allows to find out what meaning civil servants put into the concept of work-life balance. Thus, being a subjective phenomenon, this concept is primarily associated with the proportional distribution of time for family and work. Based on the results of the questionnaire survey, the authors distinguish two groups of civil servants who do and do not experience a sense of work-life balance and analyse their socio-demographic characteristics, life priorities, attitude to work, assessments of time resources and level of satisfaction with various life spheres. Representing subjective assessments, the authors note that just over half of the civil service employees surveyed do not experience work-life balance. Statistical analysis showed that the selected groups do not have significant socio-demographic differences. It was also found that civil servants, who differently assess the presence of work-life balance, do not differ significantly in determining the leading life priorities, putting family and work in the foreground. However, statistically significant links were found between subjective indicators of work-life balance and peculiarities of differentiation of work and personal problems, assessment of sufficiency of time for everyday practices and satisfaction with private life. It was found that the state of imbalance is more characteristic of people who note the influence of work on personal affairs, experience a lack of time for everyday private life and are not satisfied with its main components. The interviewing focused on a group of external factors that relate to the conditions of employment, which is important to consider in matters of personnel policy and work organisation in the public service. The obtained materials allowed to consider the existing working regime from the point of view of civil servants, to discuss initiatives for its improvement, opportunities and limitations of remote work.

Interleukin-1 gene polymorphism in a Well-maintained periodontal patient population
Authors: Caffesse Raul G. , De La Rosa R. Manuel , De La Rosa G. Manuel
Published: April 2024

Genetics is considered one of the systemic factors which modulates the host response to bacterial plaque. Individuals showing interleukin-1 gene polymorphism are more prone to develop moderate to severe periodontitis. The prevalence of genotype positive individuals has been estimated around 30% in different populations studied. We have determined a 26% prevalence in a Hispanic population. At the present, minimal information is available related to the response of genotype positive subjects to periodontal therapy. This study assessed restrospectively the response to periodontal treatment in a Hispanic population according to genotype polymorphism. 28 Hispanic subjects regularly maintained in a private practice after receiving comprehensive periodontal therapy, were tested for the interleukin-1 gene polymorphism applying the PST Genetic Test*. Full mouth gingival index, probing pocket depth and clinical attachment levels were recorded, as well as their age and smoking habit. Mean values were compared for genotype positive and negative subjects. Records were reviewed to establish an individual profile of the maintenance needs for each subject. The prevalence of genotype positive subjects was 28%. No differences were found in any of the parameters evaluated between genotype positive and negative subjects. No teeth were lost during maintenance (ranging from 4 to 30 years). However the maintenance demands of the genotype positive subjects were much more stringent, requiring shorter recall intervals, routine scaling and root planing and surgical retreatment almost on an yearly basis. Within the limits of this study it can be concluded that 1) periodontal health can be maintained after treatment in spite of genotype, and 2) genotype positive subjects require closer supervision and more surgical retreatments to achieve periodontal stability.

Published: April 2024

Euonymus bungeanus Maxim. is a tree species with high ornamental, industrial, and medicinal value. Establishing a method for rapid and efficient regeneration of E. bungeanus is essential to achieve industrial-scale production. The aim of this study was to establish a rapid tissue propagation technique for E. bungeanus and provide a foundation for the industrial production of tissue-cultured seedlings. Using stem segments of E. bungeanus as explants, we investigated effects of explant collection time, sterilization method, various culture media, and ratios of plant growth regulators on the initiation, subculture, and rooting stages of the tissue culture process for E. bungeanus. The optimal explant collection time was mid-April; a combination of 75% ethanol for 20 s, followed by 0.1% HgCl2 for 7 min was suitable for disinfection, yielding a survival rate of 55.00% for the explants. Initiation culture using the woody plant medium (WPM) supplemented with 1.0 mg L-1 of 6-benzylaminopurine (6-BA) and 0.2 mg L-1 of α-naphthalene acetic acid (NAA) achieved an induction rate of 87.22% for explants. Proliferation culture on ¼ WPM medium containing 2.0 mg L-1 of 6-BA and 0.1 mg L-1 of NAA resulted in a propagation coefficient of 4.98. Rooting culture on ½ Murashige and Skoog (MS) medium supplemented with 0.2 mg L-1 of indole-3-butyric acid achieved a rooting rate of 78.33%. However, the rooting rate was low, indicating the need for further optimization of rooting and acclimatization. This study is the first to develop a rapid and efficient regeneration system for E. bungeanus using stem segments.

Published: April 2024

Air pollution has been a significant environmental and public health concern in Ulaanbaatar, the capital city of Mongolia, for many years. The city experiences severe air pollution, particularly during the winter months. To gain better insights into this issue, the present study investigated the annual trends of outdoor and indoor PM2.5 concentrations at two neighboring sites in Ulaanbaatar: an Office and a household, using low-cost sensors. Both locations exhibited similar fluctuations in outdoor PM2.5 concentrations over time, with ambient PM2.5 levels rising in October and declining in April. During the mid-term of the heating season (November to February), hourly averaged PM2.5 concentrations were exceptionally high, with peak pollution events exceeding ~ 1000 µg/m³. Notably, PM2.5 concentrations were elevated during this heating season period. Time-activity patterns showed a decrease in PM2.5 concentrations during the periods of 6–8 AM and 2–6 PM. Besides, the study found that the indoor environment could remain safe when windows were well-sealed, even under severe outdoor pollution conditions. Overall, this study provided accurate insights into the annual patterns of PM2.5 concentrations and demonstrated how they fluctuated during the heating season when pollution levels were particularly high. The findings offer valuable recommendations for individuals to consider when going outside and taking action to improve indoor air quality in Ulaanbaatar.

Background
There has been an ongoing debate surrounding the optimal range for plasma colloid oncotic pressure (COP) in infants during CPB. Previous studies have focused primarily on the impact of low COP, while little attention has been paid to the potential risks of high COP, which may also lead to adverse effects. This retrospective study aimed to investigate the relationship between post-CPB COP and postoperative AKI in neonates and infants under 10kg.
Method
This retrospective clinical study consecutively included neonates and infants under 10kg who were diagnosed with CHD and underwent cardiopulmonary bypass at our center between May 2020 and September 2022. According to the median value of post-CPB COP in the study population, infants were classified into the low COP group (post-CPB COP ≤ 16mmHg) and the high COP group (post-CPB COP > 16mmHg). Demographic information, CPB details, COP measurements, renal adverse events, and clinical outcomes were compared between the two groups. The independent association of post-CPB COP with postoperative AKI was identified and adjusted using multivariable logistic regression analysis.
Results
131 neonates and infants with CHD under 10kg underwent cardiac surgery with CPB were included in the study. The incidence of postoperative AKI was significantly higher in the higher post-CPB COP group (COP >16mmHg) than lower post-CPB COP group (COP ≤ 16mmHg) [7(10%) vs. 17(27.9%), p = 0.008)]. A higher post-CPB COP level independently increased the risk of postoperative AKI[OR(95%CI) 1.259(1.029,1.541), p = 0.025], controlling for age, gender, cardiopulmonary duration, 25%ALB infusion per kg and circulatory arrest. Subgroup analysis showed that post-CPB COP above 16 was an independent predictor for postoperative AKI[OR(95%CI) 4.985(1.315, 18.895), p = 0.018] in infants ≤ 6 months.
Conclusion
The present study demonstrated that elevated post-CPB COP was associated with increased risks of postoperative AKI in neonates and infants under 10kg, especially in infants below 6 months.

Aside from being a significant source of highly nutritious and medicinally valuable mushrooms, mushroom cultivation is an important means of environmental remediation. Oyster (Pleurotus ostreatus) mushroom is very easy-to grow type of mushroom which can be simply grown in different environmental conditions and various types of non-composted lignocellulosic wastes. This study was conducted to assess the growth response of oyster mushroom on sesame stalk. Spawn was prepared from a mycelium culture grown on Potato Dextrose Agar. The spawn was inoculated to the substrates formulated from sesame stalk and wheat straw and incubated at room temperature in the dark for 21 days. Data was analyzed using Minitab software version 19. Significant (P<0.05) differences in days taken for mycelial colonization, primordial appearance and maturity as well as yield was observed between the substrate formulations. Treatment 1 was fastest (19.00 days) in mycelial colonization period but statistically parity with Treatment 2. Treatment 2 was faster (3.33 days) for primordial appearance while Treatment 1 was faster (6.67 days) in maturity. The highest yield (1850 g) and biological efficiency (185%) was recorded by Treatment 1. Pearson’s correlation showed that cap diameter and stipe length directly correlate with its yield and biological efficiency and faster substrate colonization leads to quicker maturation. This study suggests that sesame stalks can be a highly viable alternative to expensive substrates for successful cultivation of oyster mushrooms.

Neuronal apoptosis persists throughout ischemic stroke and leads to massive neuron loss, which severely hampers the recovery of neurological function. Clinical evidence has confirmed that EA effectively improves neurological function after stroke, but the undergoing mechanism still needs to be fully clarified. In this study we found that apoptosis and autophagy were activated after ischemic stroke, howerver EA further upregulated autophagy and inhibit neuronal apoptosis. Furthermore, the neuroprotective effect of EA was associated with the activation of mitophagy. Mechanistically, EA upregulated the expression of PGAM5 to promote FUNDC1 dephosphorylation, and then enhanced the affinity of FUNDC1 with LC3, ultimately activating PGAM5/FUNDC1-dependent mitophagy. Enhanced mitochondrial autophagy reduced the release of ROS and Cytc from damaged mitochondria, inhibited the activation of Caspase3 and subsequent neuronal apoptosis. Meanwhile, it also upregulated the level of FUNDC1 and further promoted mitophagy through the PGAM5/FUNDC1 pathway. Notably, inhibition of mitophagy by lateral ventricle injection of 3-MA significantly reversed the neuroprotective effect of EA. In summary, activating mitophagy by EA to inhibit neuronal apoptosis is a potential mechanism in post-stroke neurorepair.
AUG exhibits the strongest pulse intensity within the ribosomal decoding site

Within a messenger RNA (mRNA) are the instructions for building proteins. mRNA provides this information using nucleotides in groups of three, called codons. The ribosome moves along the mRNA and reads each codon within the ribosomal decoding site. Once the codon with nucleotides AUG appears in the decoding site, protein synthesis begins. The corresponding transfer RNA (tRNA) then brings the correct protein to the ribosome. What motion is occurring within the decoding site as AUG begins this translation process? Here we show codons interacting with the decoding site’s moving parts, flippers A1492 and A1493. Using an equation for motion, both the codons and the decoding site have numbers applied to them that are closely associated with a Pulse Grading Scale (PGS). This scale is used to grade the intensity (strength) of pulsations such as those found in the wrist, the heart, and other places within a biological system. Cells in these pulsing places also contain ribosomes that are reading mRNA. Therefore, pulsing is happening during translation. When accounting for velocities, variable constants, molar masses, and acceleration and deceleration, AUG is the mRNA codon creating the strongest level of pulse strength within the ribosomal decoding site.

Background:
The timely recognition of risk factors assumes paramount importance in the prevention of IBD. Our objective is to elucidate the relationship between risk factors and IBD risk.
Methods:
To investigate the associations between 24 modifiable risk factors and IBD, a combination of univariate and multivariate MR analysis methods was employed. The final outcomes were assessed through a comprehensive analysis of three large independent GWAS.
To mitigate confounding biases, we conducted univariate MR analysis for each individual factor. Multivariate MR analysis was performed within each group to account for the influence of multiple factors simultaneously.
Results:
RA, asthma, the intake of cheese spread, carotene, and college or university degree were negatively associated with IBD risk. MS, PSC, AS, alcohol consumption, gut microbiota abundance, smoking, and sweet intake exhibited positive correlation with IBD risk. Type 2 diabetes, omega-3 fatty acids were correlated with reduced IBD risk. Total testosterone levels and albumin exhibited associations with IBD risk. Primary hypertension, body fat percentage, and whole-body fat mass suggested increased IBD risk. Three large-scale GWAS independently confirmed that gut microbiota abundance, primary hypertension, MS, PSC, AS, whole-body fat mass, and body fat percentage exhibited stronger associations with IBD risk. Conversely, omega-3 fatty acids, RA, asthma, type 2 diabetes, and attainment of a college or university degree were related to decreased IBD risk.
Conclusions:
Such robust evidence has the potential to inform preventive measures for IBD and, notably, illuminate pathways for future research endeavors.

Notch signaling is a critical regulator of multiple developmental processes through its ability to control gene expression, and thereby influence cell fate specification and cell proliferation, through direct cell-cell communication. Although Notch signalling has been implicated in myogenesis during late embryogenesis, the role of Notch signalling in early mesoderm development has been largely unexplored. Endocytosis of the Notch ligand Delta and the Notch receptor extracellular domain, a critical step in Notch pathway activation, has been extensively observed in the ventral mesoderm of the early Drosophila embryo, indicating a potential for Notch signalling activity in this early germ layer. Here we present evidence that genes critical to mesoderm development require and are responsive to Notch signalling activity. Using a novel light-inducible Optogenetic variant of the Notch intracellular domain (OptoNotch), which affords precise spatial and temporal control over ectopic activation of Notch signalling. Using a combination of high-resolution fluorescent RNA in situ hybridization and qPCR, we identified a set of mesodermal genes that are directly regulated by Notch signalling. We also provide evidence that Notch signalling indirectly regulates the dorsal-ventral patterning program mediated by the Toll signalling pathway through the Dorsal/ Twist/ Snail network. Our findings demonstrate that Notch signalling regulates ventral mesoderm patterning and is critical for establishing the mesoderm-mesectoderm-ectoderm boundary by regulating gene expression patterns and providing negative feedback on the upstream patterning network.

We leveraged machine learning (ML) techniques, namely logistic regression (LR), random forest (RF), support vector machine (SVM), extreme gradient boosting (XGBoost), and LightGBM to predict coronary heart disease (CHD) and identify the key risk factors involved. Based on the Suita study, 7672 men and women aged 30 to 84 years without cardiovascular disease were recruited from 1989 to 1999, in Suita City, Osaka, Japan. Over an average period of 15 years, participants were diligently monitored until the onset of their initial cardiovascular event or relocation. CHD diagnoses encompassed primary heart attacks, sudden death, or coronary artery disease with bypass surgery or intervention. RF achieved the highest AUC (95% CI) of 0.79 (0.70–0.87), outperforming LR, SVM, XGBoost, and LightGBM. Shapley Additive Explanations (SHAP) on the best model identified the top CHD predictors. Notably, systolic blood pressure, non-HDL-c, glucose levels, age, metabolic syndrome, HDL-c, estimated glomerular filtration rate, hypertension, elbow joint thickness, and diastolic blood pressure were key contributors. Remarkably, elbow joint thickness was identified as a previously unrecognized risk factor associated with CHD. These findings indicated that ML methods accurately predict incident CHD risk. Additionally, ML has identified new incident CHD risk variables.
