The congruency sequence effect (CSE) is one of the most investigated effects in the cognitive control literature. The conflict monitoring theory suggests that the CSE is the result of adjustments in cognitive control based on perceived conflict. A recent paper by Zhang and colleagues, has investigated whether the manipulation of conflict level by changing distractor incompatibility in a flanker task affects the amount of adjustments in cognitive control. Their study produced mixed findings, somewhat supporting the original conflict monitoring theory, but also suggesting other explanations, such as the repetition expectancy account. We replicated the experimental design in a multisite online study (N = 347), with Hungarian, Italian, and Singaporean participants. Our results supported the prediction that changes in the level of conflict trigger conflict adaptation, revealing that increasing conflict levels induced stronger adaptive control. Bayesian hypothesis testing indicated a monotonic reduction in congruency effects as a function of previous conflict strength. This finding is in line with the extension of the traditional conflict monitoring theory, as well as other theories like affective signaling and expected value of control, implying that the relationship between conflict and interference effects is gradual, rather than a binary function.

Published: February 2024

Several studies have documented that treatment by cold atmospheric pressure plasma (CAPP) on plants foster seed germination and growth in recent years. However, the molecular processes that underlie the action of CAPP on the seeds and plants remain mostly enigmatic. We here introduce gemmae of Marchantia polymorpha, a basal liverwort, as a novel model plant material suitable for CAPP research. Treating the gemmae with CAPP for a constant time interval at low power resulted in consistent growth enhancement, while growth inhibition at higher power in a dose-dependent manner. These results distinctly demonstrate that CAPP irradiation can positively and negatively regulate plant growth depending on the plasma intensity of irradiation, offering a suitable experimental system for understanding the molecular mechanisms underlying the action of CAPP in plants.

In cancer patients, psychological distress, which encompasses anxiety, depression, and somatization, arises from the complex interplay of emotional and behavioral reactions to the diagnosis and treatment, significantly influencing their functionality and quality of life. The aim was to investigate factors associated with psychological distress in cancer patients. This prospective and multicenter study, conducted by the Spanish Society of Medical Oncology (SEOM), included two cohorts of patients with cancer (localized resected or advanced unresectable). They completed surveys assessing psychological distress (BSI-18) before and after cancer treatment and coping (MINI-MAC) and spirituality (FACIT-sp) prior to therapy. A multivariable logistic regression analysis and a Structural Equation Modeling (SEM) were conducted. Between 2019 and 2022, 1807 patients were evaluated, mostly women (54%), average age 64 years. The most frequent cancers were colorectal (30%), breast (25%) and lung (18%). Men had lower levels of anxiety and depression (OR 0.66, 95% CI 0.52–0.84; OR 0.72, 95% CI 0.56–0.93). Colorectal cancer patients experienced less anxiety (OR 0.63, 95% CI 0.43–0.92), depression (OR 0.55, 95% CI 0.37–0.81), and somatization (OR 0.59, 95% CI 0.42–0.83). Patients with localized cancer and spiritual beliefs had reduced psychological distress, whereas those with anxious preoccupation had higher level. SEM revealed a relationship between psychological distress and coping strategies, emphasizing how baseline anxious preoccupation exacerbates post-treatment distress. This study suggests that age, sex, extension and location of cancer, coping and spirituality influence psychological distress in cancer patients.

Published: February 2024

DNA damage response (DDR) is an essential mechanism by which living organisms maintain their genomic stability. In plants, DDR is important also for normal growth and yield. Here, we explored the DDR of a temperate model crop barley (Hordeum vulgare) at the phenotypic, physiological, and transcriptomic levels. By a series of in vitro DNA damage assays using the DNA strand break (DNA-SB) inducing agent zeocin, we showed reduced root growth and expansion of the differentiated zone to the root tip. Genome-wide transcriptional profiling of barley wild-type and plants mutated in DDR signaling kinase ATAXIA TELANGIECTASIA MUTATED AND RAD3-RELATED (hvatr.g) revealed zeocin-dependent, ATR-dependent, and zeocin-dependent/ATR-independent transcriptional responses. Transcriptional changes were scored also using the newly developed catalog of 421 barley DDR genes with the phylogenetically-resolved relationships of barley SUPRESSOR OF GAMMA 1 (SOG1) and SOG1-LIKE (SGL) genes. Zeocin caused up-regulation of specific DDR factors and down-regulation of cell cycle and histone genes, mostly in an ATR-independent manner. The ATR dependency was obvious for some factors associated with DDR during DNA replication and for many genes without an obvious connection to DDR. This provided molecular insight into the response to DNA-SB induction in the large and complex barley genome.

Published: February 2024

Distractions are omnipresent and can derail our attention, which is a precious and very limited resource. To achieve their goals in the face of distractions, people need to regulate their attention, thoughts, and behavior; this is known asself-regulation. How can self-regulation be supported or strengthened in ways that are relevant for everyday work and learning activities? To address this question, we introduce and evaluate a desktop application that helps people stay focused on their work and train self-regulation at the same time. Our application lets the user set a goal for what they want to do during a defined period of focused work at their computer, then gives negative feedback when they get distracted, and positive feedback when they reorient their attention towards their goal. After this so-called focus session, the user receives overall feedback on how well they focused on their goal relative to previous sessions. While existing approaches to attention training often use artificial tasks, our approach transforms real-life challenges into opportunities for building strong attention control skills. Our results indicate that optimal attentional feedback can generate large increases in behavioral focus, task motivation, and self-control—benefitting users to successfully achieve their long-term goals.

In this study, we provide a comprehensive clinical and molecular biological characterization of radiation-induced gliomas (RIG), including a risk assessment for developing gliomas. A cohort of 12 patients who developed RIG 9.5 years (3–31 years) after previous cranial radiotherapy for brain tumors or T-cell acute lymphoblastic leukemia was established. The derived risk of RIG development based on our consecutive cohort of 371 irradiated patients was 1.6% at 10 years and 3.02% at 15 years. Patients with RIG glioma had a dismal prognosis with a median survival of 7.3 months. We described radiology features that might indicate the suspicion of RIG rather than the primary tumor recurrence. Typical molecular features identified by molecular biology examination included the absence of Histon3 mutation, methylation profile of pedHGG-RTK1 and the presence of recurrent PDGFRA amplification and CDKN2A/B deletion. Of the two long-term surviving patients, one had gliomatosis cerebri, and the other had pleomorphic xanthoastrocytoma with BRAF V600E mutation. In summary, our experience highlights the need for tissue diagnostics to allow detailed molecular biological characterization of the tumor, differentiation of the secondary tumor from the recurrence of the primary disease and potentially finding a therapeutic target.
Hypothermia increases adenosine monophosphate and xanthosine monophosphate levels in the mouse hippocampus, preventing their reduction by global cerebral ischemia

Published: February 2024

Global cerebral ischemia (GCI) caused by clinical conditions such as cardiac arrest leads to delayed neuronal death in the hippocampus, resulting in physical and mental disability. However, the mechanism of delayed neuronal death following GCI remains unclear. To elucidate the mechanism, we performed a metabolome analysis using a mouse model in which hypothermia (HT) during GCI, which was induced by the transient occlusion of the bilateral common carotid arteries, markedly suppressed the development of delayed neuronal death in the hippocampus after reperfusion. Fifteen metabolites whose levels were significantly changed by GCI and 12 metabolites whose levels were significantly changed by HT were identified. Furthermore, the metabolites common for both changes were narrowed down to two, adenosine monophosphate (AMP) and xanthosine monophosphate (XMP). The levels of both AMP and XMP were found to be decreased by GCI, but increased by HT, thereby preventing their decrease. In contrast, the levels of adenosine, inosine, hypoxanthine, xanthine, and guanosine, the downstream metabolites of AMP and XMP, were increased by GCI, but were not affected by HT. Our results may provide a clue to understanding the mechanism by which HT during GCI suppresses the development of delayed neuronal death in the hippocampus.

Disease outbreaks can drastically disturb the environment of surviving animals, but the behavioural, ecological, and epidemiological consequences of disease-driven disturbance are poorly understood. Here, we show that an outbreak of High Pathogenicity Avian Influenza Virus (HPAIV) coincided with unprecedented short-term behavioural changes in Northern gannets (Morus bassanus). Breeding gannets show characteristically strong fidelity to their nest sites and foraging areas (2015–2019; n = 120), but during the 2022 HPAIV outbreak, GPS-tagged gannets instigated long-distance movements beyond well-documented previous ranges and the first ever recorded visits of GPS-tagged adults to other gannet breeding colonies. Our findings suggest that the HPAIV outbreak triggered changes in space use patterns of exposed individuals that amplified the epidemiological connectivity among colonies and may generate super-spreader events that accelerate disease transmission across the metapopulation. Such self-propagating transmission from and towards high density animal aggregations may explain the unexpectedly rapid pan-European spread of HPAIV in the gannet.

Published: February 2024

Embryo-maternal crosstalk is essential to establish pregnancy, with the equine embryo moving throughout the uterus on days 9–15 (ovulation = day 0) as part of this interaction. We hypothesized that the presence of a mobile embryo induces local changes in the gene expression of the endometrium. On Day 12, the endometrial transcripts were compared among three groups: uterine horn with an embryo (P+, n = 7), without an embryo (P−, n = 7) in pregnant mares, and both uterine horns of nonbred mares (NB, n = 6). We identified 1,101 differentially expressed genes (DEGs) between P+ vs. NB and 1,229 DEGs between P− vs. NB. The genes upregulated in both P+ and P− relative to NB were involved in growth factor pathway and fatty acid activation, while downregulated genes were associated with oxytocin signaling pathway and estrogen receptor signaling. Comparing the transcriptome of P+ to that of P−, we found 59 DEGs, of which 30 genes had a higher expression in P+. These genes are associated with regulating vascular growth factors and the immune system, all known to be essential in early pregnancy. Overall, this study suggests that the mobile embryo influences the endometrial gene expression locally.
Into the Holocene, anatomy of the Younger Dryas cold reversal and preboreal oscillation
Authors: Velay-Vitow Jesse , Chandan Deepak , Peltier W. Richard
Published: February 2024

During the most recent deglaciation, the upwards trend of warmer Northern Hemisphere (NH) temperatures was punctuated by a rapid and intense return to glacial conditions: the Younger Dryas (YD). The end of this event marks the beginning of the Holocene. Using the University of Toronto version of CCSM4, a model of the climate prior to the YD was created with correct boundary conditions. Various amounts of freshwater forcing were then applied to the Beaufort Gyre for forcing intervals ranging from 1 to 125 years. In several cases, this was sufficient to collapse the Atlantic Meridional Overturning Circulation (AMOC) and cause significant cooling over the NH. Crucially, after the forcing was ceased, the AMOC stayed in an off state for approximately a millennium before mounting a rapid recover to pre-YD levels. This recovery, which permanently reduced the extent of NH sea ice, occurred through the mechanism of a Polynya opening in the Irminger Sea during winter and led to a pronounced “overshoot” of the AMOC, during which NH temperatures were higher than before the YD.

Proinflammatory cytokines, such as (IL: interleukin) IL-6 and IL-17A, and complement fixation are critical in the immunopathogenesis of neuromyelitis optica spectrum disorders (NMOSD). Blocking the IL-6 receptor or the C5 complement pathway reduces relapse risk. However, the role of interleukin (IL)-6 and complement in aquaporin-4 (AQP4) autoimmunity remains unclear. To investigate the role of the anti-AQP4 immunoglobulin (AQP4-IgG)/AQP4 immunocomplex on the induction and profile of ex vivo cytokine and surface marker expression in peripheral blood mononuclear cells (PBMC) culture. Isolated PBMCs obtained from 18 patients with AQP4-IgG-seropositive-NMOSD (8 treatment-naive, 10 rituximab-treated) or ten healthy controls were cultured with AQP4-immunocomplex with or without complement. Changes in PBMC surface markers and cytokine expression were profiled using flow cytometry and ELISA. PBMCs derived from treatment-naive NMOSD patients stimulated with a complex mixture of serum complement proteins produced significant elevations of IL-17A and IL-6. Rituximab-treated patients also exhibited higher IL-6 but not IL-17A release. IL-6 and IL-17A elevations are not observed without complement. Co-stimulation of PBMCs with AQP4-IgG/AQP4 immunocomplex and complement prompts a Th17-biased response consistent with the inflammatory paradigm observed in NMOSD. A possible inflammation model is proposed via antigen-specific autoreactive peripheral blood cells, including NK/NKT cells.

Published: February 2024

Sparganii Rhizoma-Curcumae Rhizoma (SR-CR) is a classic drug pair for the treatment of castration-resistant prostate cancer (CRPC), but its mechanism has not been clarified. The study aims to elucidate the potential mechanism of SR-CR in the management of CRPC. The present study employed the TCMSP as well as the SwissTargetPrediction platform to retrieve the chemical composition and targets of SR-CR. The therapeutic targets of CRPC were identified through screening the GeneCards, Disgenet, and OMIM databases. Subsequently, the Venny online platform was utilized to identify the shared targets between the SR-CR and CRPC. The shared targets were enrichment analysis using the Bioconductor and Kyoto encyclopedia of genes and genomes (KEGG) databases. The active ingredients and core targets were verified through molecular docking and were validated using PC3 cells in the experimental validation phase. A total of 7 active ingredients and 1126 disease targets were screened from SR-CR, leading to a total of 59 shared targets. Gene Ontology (GO) analysis resulted in 1309 GO entries. KEGG pathways analysis yielded 121 pathways, primarily involving cancer-related signaling pathways. The results from molecular docking revealed stable binding interactions between the core ingredients and the core targets. In vitro cellular assays further demonstrated that SR-CR effectively suppressed the activation of the Prostate cancer signaling pathway in PC3 cells, leading to the inhibition of cell proliferation and promotion of apoptosis. The SR-CR exert therapeutic effects on CRPC by inhibiting cell proliferation and promoting apoptosis through the Prostate cancer signaling pathway.
Climatological Madden-Julian Oscillation during boreal spring leads to abrupt Australian monsoon retreat and Asian monsoon onsets
Authors: Wang Bin , Dai Lun , Cheng Tat Fan , Lee Sun-Seon , Wang Tianyi , Jin Chunhan
Published: February 2024

Abrupt monsoon onsets/retreats are indispensable targets for climate prediction and future projection, but the origins of their abruptness remain elusive. This study establishes the existence of three climatological Madden-Julian Oscillation (CMJO) episodes contributing to the rapid Australian summer monsoon retreat in mid-March, the South China Sea (or East Asian) summer monsoon onset in mid-May, and the Indian summer monsoon onset in early June. The CMJO displays a dynamically coherent convection-circulation structure resembling its transitionary counterpart, demonstrating its robustness as a convectively coupled circulation system and the tendency of the transient MJOs’ phase-lock to the annual cycle. The CMJO is inactive during the boreal winter due to destructive year-to-year modulations of El Niño-Southern Oscillation. We hypothesize that the interaction between atmospheric internal variability (MJO) and the insolation-forced slow annual cycle generates the sudden monsoon withdrawal/onset during the boreal spring. Understanding the factors determining the timing and location of the MJO’s phase-locking and its variability is vital for monsoon forecasting and climate projection.

Published: February 2024

The characterization of the vibrations of the middle ear ossicles during sound transmission is a focal point in clinical research. However, the small size of the structures, their micrometer-scale movement, and the deep-seated position of the middle ear within the temporal bone make these types of measurements extremely challenging. In this work, dynamic synchrotron-based X-ray phase-contrast microtomography is used on acoustically stimulated intact human ears, allowing for the three-dimensional visualization of entire human eardrums and ossicular chains in motion. A post-gating algorithm is used to temporally resolve the fast micromotions at 128 Hz, coupled with a high-throughput pipeline to process the large tomographic datasets. Seven ex-vivo fresh-frozen human temporal bones in healthy conditions are studied, and the rigid body motions of the ossicles are quantitatively delineated. Clinically relevant regions of the ossicular chain are tracked in 3D, and the amplitudes of their displacement are computed for two acoustic stimuli.

The company has several suppliers to meet the needs of raw materials for t-shirt products. Currently, the selection of suppliers is considered not optimal because there are still problems that result in hampering the production process. Therefore, companies need the right way to select suppliers. This problem can be overcome using the Fuzzy Analytical Hierarchy Process (F-AHP) method. This method is a combination of Analytical Hierarchy Process (AHP) method with fuzzy concept. Fuzzy overcomes the weaknesses of the AHP method, minimizing the level of subjectivity in an assessment of AHP to get more accurate decision results. The result of F-AHP method is supplier priority with more objective results based on priority selection criteria.

Published: February 2024

Alternatives to traditional fossil-based energy generation are required to combat climate change and air pollution. Solar power has become increasingly appealing due to its infinite supply, ability to mitigate climate change, and non-polluting nature. The semi-transparent photovoltaics have a portion of the cell that allows light to pass through while the rest of the cell generates electricity. Energy analysis on semi-transparent photovoltaic is needed to determine their performance. The studied semi-transparent photovoltaic systems consist of ten modules combined in one panel and two separate panels. The system consists of 2x10 pieces 165 Wp Solarwatt Vision modules with 3,3 kWp capacity. The installation site’s location is the latitude 47.5946° N, 19.3619° E.

HFCs group refrigerants are still widely used in refrigerated pickup trucks. This refrigerant is a synthetic chemical and has a high potential to cause global warming and damage the ozone layer. This study aims to obtain performance data from the use of HCs as refrigerant in refrigerated pickup trucks. The research was conducted experimentally on a pickup truck with a 1500 cc engine capacity. The size of the refrigerated room is 2300 mm long, 1500 mm wide and 1400 mm high. A commercial refrigeration system (C-250e MAX, Thermo King Europe, Belgium). The size of the evaporator, which consists of a cold air supply fan and an intake fan, is 133 mm long, 985 mm wide and 525 mm high. The cooling capacity is 2770 W. The volumetric flow rate of cold air is 1100 m3/hr. The test started at 9 am and the temperature value in a gallon of water was measured for 120 minutes. The results showed that the optimal refrigerant filling was the use of R290 (35%) and R1270 (20%). The value of the coefficient of system performance obtained from the use of the two variations of HCs is 4. Thus, refrigerant HCs R290 and R1270 can replace refrigerant HFCs in refrigerated pickup trucks with refrigerant mass variations of R290 (35%) and R1270 (20%).

Organic 3.0 agro-technologies have been gaining popularity over the last decades in light of the search for solutions for sustainable environmental management and sustainable development of territories. The International Sustainable Development Goals recommend the transfer and search for new agro-technologies of gentle impact on the environment in order to maximize resource conservation and minimize anthropogenic impact on nature for future generations. The trend of transition of many countries to organic production requires additional investment and building new mechanisms of interaction in the sphere of agro-industrial complex. The paper studies the established market of organic products, assesses its structure and makes a forecast of its future expansion. Climate change and the reduction of areas suitable for the production of food raw materials impose an additional burden on agricultural production, which should use more effective methods and technologies to increase productivity in the current conditions. The conclusions are drawn about the key role of Russia in the development of the organic trend of agro-industrial complex as a country with vast agrarian territories and resources.

The digital ecosystem for the agro-industrial complex emerged as a platform that unites agrarians from all regions of Russia and stimulates the promotion of agro-technologies in rural areas. The successes demonstrated by the agribusiness sector since 2017 need to be consolidated and developed, which is why a unique industry ecosystem “Your Farm” was built on the basis of the Russian Agricultural Bank (RusAg) in the conditions of digital interaction. The digital platform is a unique megaservice that unites farmers and allows them to solve questions on the sale and supply of agricultural products. It is also used to attract various types of state support, find or train qualified employees, develop agro-tourism and promote rural areas. It also allows farmers to form a real estate database. RusAg ecosystem continues to develop and expand its services, the number of users of the platform’s services is increasing, the popularity of rural lifestyle is growing. The “Your Farm” digital ecosystem has turned an industry bank into a technological platform. It promotes technical modernization of the agro-industrial complex, expands its export potential, attracts specialists to work in rural areas, and improves the quality of life in the regions.

The current stage of national state formation is characterized by democratization and improvement of the national legal system. In such conditions, special attention is paid to the formation of the legal base of Uzbekistan, taking into account the experience of the world communities. The main vector of the constitutional reform started in Uzbekistan is to ensure the decentralization of national power, which today serves as the main tool for changing social relations and is characterized by the maximum approach of power, management tools and service to every citizen. The global business arena provides great opportunities for healthy competition, new goods and services, and activities aimed at stimulating entrepreneurial initiative. Small business only needs to overcome the technological backwardness, increase the competitiveness of local products, and finally get out of the monopolized, unprofitable economy and oligarchy that everyone is familiar with.

The results of three years of research (2021-2023) are presented to study the effectiveness of pre-sowing treatment of seeds of grain crops (spring wheat, spring barley and oats) to regulate growth and development, increase yields and improve product quality. The research was carried out on leached chernozem of the Novosibirsk Ob region (JSC Irmen breeding plant, Ordynsky district, Novosibirsk region) and on gray forest soil (TPP “Michurintsev Garden”). The varieties of grain crops (spring wheat Licamero, spring barley Paustian and oats – Max) were studied. An increase in leaf area parameters was established against the background of the use of preparations for treating seeds with subsequent spraying of plants in the tillering phase with the following growth regulators Siliplant 0.01% (based on chelate forms), Epin-Extra 0.005%, Zircon 0.005%, Toro Combi 0.02% solution and Turmax 0.025% (chelate forms of macro and microelements). It was shown that the use of growth regulators increased the rate of growth and development, productivity and product quality. It was statistically established that the yield of grain crops depended on the elements - 38%, the crop under study - 31%, growth regulators and year conditions by 24%.

This study demonstrates the possibility of crop rotation selection based on the assessment of productivity and sustainability of crop production under different atmospheric moisture conditions. The study considers 8 crop rotations oriented to grain production. The data obtained in long-term field experiments in the forest-steppe of the Novosibirsk region were used. As a result of the implementation of the decision tree (CART) and the use of ensemble algorithm (Random Forest) the construction of a model characterized by a fairly high predictive ability was performed. Standardized Precipitation Index was chosen as the main predictor characterizing atmospheric moistening in different periods of vegetation. The most stable from the point of view of stability of crop yield – grain-fallow with winter rye, grain-fallow with legumes (vetch-oats), in conditions of manifestation of atmospheric drought of different severity were selected. The possibility of using machine learning methods (CART, Random Forest) as effective tools in the selection of crop rotation for sustainable grain production without the use of chemicalization in soil and climatic conditions of Siberia, as well as the assessment of possible risks in the transition of crop production to organic technologies were scientifically substantiated.

The development of physical models that take into account the combined influence of the dynamics of surface and ground waters is an important task for solving the problem of flooding of settlements during floods. These models allow improving the accuracy of modeling considering more complex physical processes, adapting to changing climatic conditions and integrating with other control systems. This paper explores the use of cyber-physical methods for modeling the flood zones of settlements during floods. The MODFLOW software product was used to simulate the flood zones of settlements. The developed model makes it possible to analyze hydrological processes, including groundwater dynamics and interaction with surface water bodies. Neural network models have also been developed and tested that use geographic, meteorological, hydrological, and structure and infrastructure data to predict the boundaries of flood zones.

The quality of vegetable oils intended for consumption depends on the complete and perfect deodorization process. Unpleasant taste and odor volatile substances contained in vegetable oils are composed of a complex complex of substances with different composition in terms of quality and quantity. They have more vapor elasticity compared to triglycerides, that is, they create volatility. In the process of deodorization, the odorous substances in the liquid layer move to the evaporation layer, and the molecules of the evaporated substances are lost. Based on the scientific results obtained on the improvement of the deodorization technology of oils on the basis of the computer model of the deodorization process in the liquid-steam-floating nozzle system: in a short time and using modern cleaning methods, it is possible to recommend the optimal conditions for the preparation of high-quality, harmless cottonseed oil for the human body.
