description: Background: There are currently no recommendations guiding when best to perform coronary artery calcium (CAC) scanning among young adults to identify those susceptible for developing premature atherosclerosis. Objectives: The purpose of this study was to determine the ideal age at which a first CAC scan has the highest utility according to atherosclerotic cardiovascular disease (ASCVD) risk factor profile. Methods: We included 22,346 CAC Consortium participants aged 30-50 years who underwent noncontrast computed tomography. Sex-specific equations were derived from multivariable logistic modeling to estimate the expected probability of CAC >0 according to age and the presence of ASCVD risk factors. Results: Participants were on average 43.5 years of age, 25% were women, and 34% had CAC >0, in whom the median CAC score was 20. Compared with individuals without risk factors, those with diabetes developed CAC 6.4 years earlier on average, whereas smoking, hypertension, dyslipidemia, and a family history of coronary heart disease were individually associated with developing CAC 3.3-4.3 years earlier. Using a testing yield of 25% for detecting CAC >0, the optimal age for a potential first scan would be at 36.8 years (95% CI: 35.5-38.4 years) in men and 50.3 years (95% CI: 48.7-52.1 years) in women with diabetes, and 42.3 years (95% CI: 41.0-43.9 years) in men and 57.6 years (95% CI: 56.0-59.5 years) in women without risk factors. Conclusions: Our derived risk equations among health-seeking young adults enriched in ASCVD risk factors inform the expected prevalence of CAC >0 and can be used to determine an appropriate age to initiate clinical CAC testing to identify individuals most susceptible for early/premature atherosclerosis.

description: In the field of children’s literature studies, much attention has been devoted to investigating differences between children’s and adult literature. Works of crosswriters, authors who write for both readerships in different works, are an excellent source for this research. This article applies stylometry, the computational method of analysing style, to the oeuvres of 10 Dutch and English crosswriters to trace potential differences in their individual style and similarities between the authors. The analyses also take into account the age of the intended reader (as listed in the paratext) and the publication date, to study the influence these aspects have on writing style. Four case studies zoom in on a specific author or age category of the intended readership to study general tendencies as well as outliers. The results from the stylometric analyses are complemented with peritextual information about the author’s view on style and writing for readerships of different ages. The main conclusion drawn from the case studies is that the style of the texts usually correlates more strongly with the age of the intended reader than with the time period in which it was written. Young adult literature clusters more closely with adult literature. The style associated with a younger readership is distinct in the oeuvres of most authors studied in this article and even transcends the differences between authors.

description: Wax deposition in crude oil pipelines critically undermines flow efficiency and increases operational costs, yet the aging behavior of wax deposits in polyethylene pipelines under water-containing conditions remains underexplored. This study presents systematic investigation into the water-containing aging dynamics of wax deposits in polyethylene pipelines, addressing a gap in multiphase flow deposition research. A flow loop with interchangeable polyethylene and steel test sections was employed to conduct wax deposition experiments under water contents (0–50 vol%) and temperature conditions (bulk 25–29 °C, wall 19–23 °C). Differential scanning calorimetry was used to quantify wax content, while heat transfer and wax precipitation analysis provided insights. Innovatively, polyethylene pipes demonstrated 16.3–68.3% lower aging rates than steel pipes under identical conditions, directly attributed to their 15.6–32.2% lower radial concentration gradients. This reduction is linked to polyethylene’s inherently lower thermal conductivity, establishing a novel material-driven correlation in wax deposition dynamics. Notably, when the water content reaches 50 vol%, this causes phase inversion of the emulsion, resulting in negative aging rates of the deposition layer. These findings redefine design parameters for high-water-cut polyethylene pipelines, enabling predictive maintenance to minimize pigging frequency.

description: This presentation serves as a reader-friendly guide to the fundamental basics and modern implications of standard nuclear magnetic resonance imaging (NMRI) modalities and practical applications. The discussion begins on the sub-atomic level with the precession of protons within the body. This discussion walks through each step in the NMRI process- from proton alignment to transverse and longitudinal relaxation, and pulse sequences. Furthermore, a focus is placed on the quantitative aspect of NMRI. Quantitative measurements such as related formulas, time constants, and more are analyzed. Included in the discussion are modern implications of NMRI. Specifically, the usage of T1 and T2 images in order to study Multiple Sclerosis (MS) demyelination and progression over time.

description: Science communication and science education are closely interlinked. Science education provides uniquely powerful opportunities to advocate Drosophila by reaching out to audiences at young age. This workshop will introduce to effective strategies and resources for extracurricular school events, curricular lessons taught by teachers, K12 practicals, and the training of university students. All these modalities use the fly as a teaching tool, introducing students to the idea of Drosophila research through teaching science WITH flies rather than educating ABOUT flies. Both, the scientist and the teacher perspective will be explained, alerting to the need of engaging in true school collaboration.

description: This article aimed to display the stability and demulsification characteristics of oil displacing Pickering emulsions, which have excellent stability and exhibit fast demulsification properties under the action of non-uniform, high-frequency, high-voltage electric fields. The surface of SiO2 nanoparticles was modified by silane coupling agent to obtain hydrophobic modified SiO2 nanoparticles for preparing the Pickering emulsion. Experiments showed that the stability of Pickering emulsions improved with increasing nanoparticles concentration. Applying a non-uniform electric field at high frequency and high voltage for 4 min was shown to successfully demulsify and dehydrate Pickering emulsions. The dehydration efficiency gradually increased when the electric field voltage was increased from 3 to 7 kV, but the growth rate gradually decreased; when the electric field frequency increased from 1 to 5 kHz, the dehydration efficiency increased in a stepwise manner, but the variation was extremely limited. The best dehydration effect was achieved at 7 kV and 5 kHz, with a dehydration efficiency of 63.6%. Based on the electric field distribution characteristics and particle force analysis, it is proposed that the intrinsic cause of emulsion demulsification is the movement and redistribution of nanoparticles along the electric field intensity gradient direction at the droplet interface by dielectrophoretic force.

description: Metabolic mechanisms underlying the heterogeneity of major adverse cardiovascular (CV) event (MACE) risk in individuals with type 2 diabetes mellitus (T2D) remain unclear. We hypothesized that circulating metabolites reflecting mitochondrial dysfunction predict incident MACE in T2D. Targeted mass-spectrometry profiling of 60 metabolites was performed on baseline plasma samples from the Trial Evaluating Cardiovascular Outcomes with Sitagliptin (TECOS; discovery cohort) and Exenatide Study of Cardiovascular Event Lowering (EXSCEL; validation cohort) biomarker substudy cohorts. A principal components analysis metabolite factor comprising medium-chain acylcarnitines (MCACs) was associated with MACE in TECOS and validated in EXSCEL, with higher levels associated with higher MACE risk. Meta-analysis showed that long-chain acylcarnitines (LCACs) and dicarboxylacylcarnitines were also associated with MACE. Metabolites remained associated with MACE in multivariate models and favorably changed with exenatide therapy. A third cohort (Cardiac Catheterization Genetics [CATHGEN]) with T2D was assessed to determine whether these metabolites improved discriminative capability of multivariate models for MACE. Nine metabolites (MCACs and LCACs and 1 dicarboxylacylcarnitine) were associated with time to MACE in the CATHGEN cohort. Addition of these metabolites to clinical models minimally improved the discriminative capability for MACE but did significantly down reclassify risk. Thus, metabolites reporting on dysregulated mitochondrial fatty acid oxidation are present in higher levels in individuals with T2D who experience subsequent MACE. These biomarkers may improve CV risk prediction models, be therapy responsive, and highlight emerging risk mechanisms.

description: This article pinpoints the problem of multiple clusters of crack extensions with perforation erosion, proposes a modified calculation formula for the variation of perforation diameter. Established a proposed three-dimensional numerical model to analyze the effect of different construction and completion parameters on fracture extension. The results show that: (1) With the pumping of sand-carrying fluid, the perforation erosion will lead to the increase of the flow coefficient and diameter of each cluster of perforation, which shows that the perforation erosion exacerbates the imbalance in flow distribution at the fracture inlet of each cluster as well as the non-uniform expansion of multi-cluster cracks. (2) The effect of perforation erosion increases with the enhancement of limited entry, and although the negative effect of perforation erosion is overall smaller than the positive effect of limited entry, it somewhat weakens the flow restriction ability of the perforation. (3) When the effect of limited entry is strengthened, considering the effect of perforation erosion the flow difference coefficient and the fracture length variation coefficient are significantly increased, and show a tendency to decrease (4) Use low proppant concentration to minimize damage to fractured pipe columns while meeting fracture inflow capacity.

description: The present work tries to demonstrate that, in South America, there is still a strong tendency towards irredentism that is expressed through the interpretation of maps. Said tendency, of course, is propitiated by many of the States of the region in question to a greater or lesser extent, for which reason, many of the claims that the South American States make against each other are generally contradictory. What is intended here is to list these territorial claims, through a slightly more impartial eye, and demonstrate that these ones, especially thanks to tools such as the internet and social networks, are still more than alive.

description: Objective Ideal cardiovascular health (CVH) was developed to promote CVH as a key component of primordial prevention. Mobile short message service (SMS) is useful for improving health behaviours. We aim to test the effectiveness of SMS intervention in women to improve CVH. Methods In a single-blinded, randomised, controlled study, 620 women, aged 35-70 years, without cardiovascular disease, were enrolled in SMS intervention versus no SMS. CVH metrics by self-report, and biochemical laboratory, anthropometric and blood pressure measurements were collected during home visits at baseline and 9 months. Women were categorised as having poor (0-2), intermediate (3-4) or ideal (5-7) CVH according to the number of ideal CVH metrics. Participants were randomised 1:1 to SMS intervention versus control. SMS was sent every 5-6 days for 9 months. The primary outcome was the difference in the proportion of women with ideal CVH between SMS and control groups at 9 months. Rates of intermediate CVH, poor CVH and each of the seven ideal CV health metrics at 9 months were key secondary endpoints. Results At 9 months, there was no significant difference between groups for the primary outcome (16.3% at baseline and 13.3% at 9 months, and 10.1% and 11.1%, in SMS and control groups, respectively, adjusted RR 1.0; 95% CI 0.6 to 1.6). Similarly, there were no significant differences between groups for the key secondary endpoints. SMS had an acceptance rate of 94.9%. Conclusions Behavioural SMS intervention did not improve rates of ideal CVH in women, despite being feasible and well received. Trial registration number 6377.

description: Recent advances in the field of immunotherapy have profoundly opened up the potential for improved cancer therapy and reduced side effects. However, the tumor microenvironment (TME) is highly immunosuppressive, therefore, clinical outcomes of currently available cancer immunotherapy are still poor. Recently, nanomaterial-based strategies have been developed to modulate the TME for robust immunotherapeutic responses. In this review, the immunoregulatory cell types (cells relating to the regulation of immune responses) inside the TME in terms of stimulatory and suppressive roles are described, and the technologies used to identify and quantify these cells are provided. In addition, recent examples of nanomaterial-based cancer immunotherapy are discussed, with particular emphasis on those designed to overcome barriers caused by the complexity and diversity of TME.

description: The açaí industry generates 1,300,000 tons of primary waste (açaí pits) annually, part of which is used to produce electricity, generating secondary waste (açaí ash) that is often discarded in rivers or on land. Meanwhile, the oil industry seeks solutions to reduce the environmental impacts of its exploratory processes. This research addresses both challenges by reusing açaí ash as an eco-friendly, low-cost additive for water-based drilling fluids. Chemical characterization via X-ray fluorescence (XRF) showed the ash is rich in potassium, phosphorus, silicon, and calcium. Fourier-transform infrared spectroscopy (FTIR) detected phosphate groups linked to carbon chains, while scanning electron microscopy (SEM) revealed an amorphous structure with high polydispersity. Açaí ash was tested as a thickening agent in eight fluid formulations, using particle sizes smaller and larger than 300 µm, compared to CaCO3. Results indicated that replacing CaCO3 with açaí ash increased plastic viscosity by 30% and yield point by 28%, with pH values between 8 and 11. Filtrate volumes ranged from 5.2 to 7.0 mL, compared to 7.3 mL for CaCO3. These findings demonstrate that açaí ash improves drilling fluid properties and mitigates environmental impacts, providing a sustainable solution for both industries.

description: Removing nitrogenous compounds from liquid fuels is essential, and adsorption de-nitrogenation is a new process for this goal. This work has the purpose of investigating quinoline adsorption using Iron functionalized Activated carbon (IFAC) mesoporous nanocomposite. The mesoporous nanocomposite was synthesized in a one-step process by chemical activation of the walnut shell using Iron chloride as the activation and modification agent. The IFAC mesoporous nanocomposite was utilized to remove quinoline from isooctane as the liquid fuel via a discontinuous (batch) process by examining the effect of initial concentration, contact time, and temperature. The effect of contact time on the adsorption ability of IFAC for quinoline was well described by the pseudo-second-order model. The Langmuir model described the equilibrium manner of the process well, and the adsorbent could retain 344.82 mg/g of quinoline (37.37 mg N/g). The thermodynamic parameters show the endothermic (ΔH°= +30.070 kJ/mol) and spontaneity of the adsorption process. The regeneration experiments indicated that functionalized AC’s adsorption ability for quinoline adsorption decreased by 23% after five cycles. The obtained data indicate that the functionalization of activated carbon surface with iron particles leads to improving its adsorption ability toward N-containing compounds from liquid fuels.

description: In order to solve the problem that the asphaltene in YM35-6 crude oil is easy to precipitate and accumulate, resulting in wellbore blockage. In this paper, an oil-soluble amphiphilic polymer asphaltene inhibitor (SYRJ) was developed. The wellbore environment was simulated by static experiments and high temperature and high-pressure dynamic experiments. The inhibition effect on asphaltene was evaluated respectively. The inhibition rate reached 84.65% and 82.03% respectively at 400 ppm dosage. Furthermore, the inhibitor showed good inhibition effect on different high asphaltene crude oils. Even at 120 °C, the inhibition rate was more than 85%. Finally, the microstructure and particle size of asphaltene after adding SYRJ were studied by scanning electron microscopy and laser scattering system. The results show that SYRJ adsorbs on the surface of asphaltene and penetrates into its crevices by virtue of its ultra-long carbon chain and hyperbranched structure. The interlayer spacing between asphaltenes is increased. Thus, the interaction between asphaltene molecules is hindered, and the growth and aggregation of asphaltene particles are inhibited. The average particle size of asphaltene molecules was reduced from 409.5 nm to 189.3 nm.

description: Breast cancer is classified into multiple distinct histologic types, and many of the rarer types have limited characterization. Here, we extend The Cancer Genome Atlas Breast Cancer (TCGA-BRCA) dataset with additional histologic type annotations in a total of 1,063 breast cancers. We analyze this extended dataset to define transcriptomic and genomic profiles of six rare, special histologic types: cribriform, micropapillary, mucinous, papillary, metaplastic, and invasive carcinoma with medullary pattern. We show the broader applicability of our constructed special histologic type gene signatures in the TCGA Pan-Cancer Atlas dataset with a predictive model that detects mucinous histologic type across cancers of other organ systems. Using a normal mammary cell differentiation score analysis, we order histologic types into a continuum from stem cell-like to luminal progenitor-like to mature luminal-like. Finally, we classify TCGA-BRCA into 12 consensus groups based on integrated genomic and histological features. We present a rich, openly accessible resource of genomic, molecular, and histologic characterization of TCGA-BRCA to enable studies across the range of breast cancers.

description: Hydraulic fracturing plays a crucial role in extracting natural gas from tight sandstones. Temperature and in-situ stress significantly influence the effectiveness of fracturing. However, the mechanisms through which these parameters enhance reservoir permeability require further investigation. We executed hydraulic fracturing and seepage experiments on tight sandstones across varying temperatures, analyzed the variation of injection pressure during the fracturing process, and compared permeability changes before and after fracturing. Our findings indicate that as the temperature rises, the breakdown pressure of the specimen decreases, with a maximum reduction of ∼26.15%, and existing theoretical models can estimate the breakdown pressure range. The specimen permeability before and after fracturing exhibited exponential decline with increased axial stress. However, the formation of penetrating fractures notably enhanced the specimen permeability after fracturing, surpassing before-fracturing levels. To quantify the impact of hydraulic fracturing on permeability, we introduced a permeability improvement coefficient, which peaked at around 15.7. This coefficient decreased as axial stress increased, with higher temperatures associated with more significant reductions. The insights from this study can guide hydraulic fracturing construction.

description: Designer receptors exclusively activated by designer drugs (DREADDs) represent a powerful chemogenetic technology for the remote control of neuronal activity and cellular signalling1–4. The muscarinic receptor-based DREADDs are the most widely used chemogenetic tools in neuroscience research. The Gq-coupled DREADD (hM3Dq) is used to enhance neuronal activity, whereas the Gi/o-coupled DREADD (hM4Di) is utilized to inhibit neuronal activity5. Here we report four DREADD-related cryogenic electron microscopy high-resolution structures: a hM3Dq–miniGq complex and a hM4Di–miniGo complex bound to deschloroclozapine; a hM3Dq–miniGq complex bound to clozapine-N-oxide; and a hM3R–miniGq complex bound to iperoxo. Complemented with mutagenesis, functional and computational simulation data, our structures reveal key details of the recognition of DREADD chemogenetic actuators and the molecular basis for activation. These findings should accelerate the structure-guided discovery of next-generation chemogenetic tools.

description: This paper represents a reevaluation of previous knowledge of the distinctive bronze lamp in the shape of a ship, discovered on the locality of Mezul, near Smederevo in Serbia, as well as new interpretations based on written sources, analogies and iconographic interpretation. The lamp is specific due to its shape and decoration, its inscription, as well as extraordinary dimensions, since it is, by far, the biggest of all the late antique lamps in the shape of a ship so far encountered. Even though many authors have written about it, numerous unanswered questions remain. Particular attention is dedicated to the ship’s symbolism in early Christianity, then to the symbolism of lamp in the shape of a ship, as well as to the complex meanings of the decoration on the lamp discovered near Smederevo. By linking the context of the finding and the lamp’s decoration with the written and material sources that testify to the historical circumstances in the Danube region in the late Roman period, this paper presents the possible connection of the lamp with yet undiscovered Christian sacral building, and its role on the local martyr cult.

description: The exploration of shale gas has increasingly emerged in recent years. In this work, the ionic liquid (IL) of 1-butyl-3-methylimidazole ferric tetrachloride was firstly used as a chemical additive to improve the dissolution of shale and enhance shale gas desorption. The analyses of total organic carbon (TOC), Fourier transform infrared spectroscopy, X-ray diffractometer, X-ray photoelectron spectroscopy, and Brunauer–Emmett–Teller measurement were performed. The results revealed that the TOC content was reduced by 66.2% using a concentration of 0.1 mol/L 1-butyl-3-methylimidazole ferric tetrachloride with a solid-liquid ratio of 1:20 at 60 °C and a duration of 48 hr and the dissolution rate of shale was 18.95 wt%. Inorganic minerals within shale were dissolved, and irregular pores were observed, which improve the permeability of shale and the flow of shale gas. Meanwhile, the characterization of residues in the solution presented that the structures of long carbon chain, carbon-sulfur and amines, amides, or heterocyclic within kerogen may be disrupted, which is beneficial for the shale gas desorption. The isothermal adsorption results proved that the adsorption capacity of methane on the kerogen treated was decreased by 53.16%, which inferred that the desorption ability of shale gas can be improved. 1-butyl-3-methylimidazole ferric tetrachloride was firstly employed to enhance shale gas desorption.The total organic carbon (TOC) content in shale treated was reduced by 66.2%.A possible reaction mechanism of shale with 1-butyl-3-methylimidazole ferric tetrachloride was proposed.The adsorption capacity of methane on kerogen was decreased by 53.16% at a pressure of 30 MPa. 1-butyl-3-methylimidazole ferric tetrachloride was firstly employed to enhance shale gas desorption.

description: The introduction of the cyclostratigraphy theory has successfully solved the high-frequency cycle division and correlation of fine-grained sedimentary rocks. However, the high-frequency cycle division of continuously deposited thick-bedded sandstones still faces major challenges. In this study, MATLAB and Acycle2.0 free software were used to divide the high-frequency cycles of the Y sandstone group in the X well area of the South Tambay Gas Field, and detailed sedimentary facies analysis was carried out on the long eccentricity cycles. The results show that the Y sandstone group was divided into four long eccentricity cycles, which were primarily formed in meandering river delta facies transformed by tide and developed delta plain and front subfacies. The subfacies were further subdivided into distributary channels, swamp, underwater distributary channels, distributary channel mouth bars, and interdistributary bay microfacies. Sandstone bodies were primarily formed in the distributary channel, underwater distributary channel, and distributary channel mouth bar microfacies. A representative and instructive sedimentary model was established. The results of the high-frequency cycle division and the new understanding of sedimentary facies agree well with the practice of oil and gas exploration and development, indicating that the cyclostratigraphy theory is applicable to high-frequency cycle division and correlation of sandstone strata. The high-frequency cycles of the Y sandstone group in the X well area of the South Tambay Gas Field were divided.Detailed sedimentary facies analysis was carried out on the long eccentricity cycles.A representative and instructive sedimentary model of the meandering river delta was established.

description: Dew point pressure plays a crucial role in the efficient development of gas condensate reservoirs. In this work, 680 experimental data points were collected and six hybrid machine learning models were developed. Each model was based on different optimization algorithms, to predict dew point pressure. The results revealed that the Extreme Learning Machine (ELM) model, optimized by the Dung Beetle Optimizer (DBO), achieved the highest prediction accuracy. Furthermore, this research introduced the novel application of an interpretable tool to reveal the underlying variation patterns between input features and output predictions. The analysis identified MWC7+ and SGC7+ as the key factors influencing dew point pressure. Finally, the proposed model’s reliability was validated, achieving a performance verification of 95.15% through domain applicability analysis. These findings offer significant insights into the prediction and optimization of dew point pressure for gas condensate reservoir development.

description: On a number of pilgrimage objects from Late Antiquity, St Thecla, a highly revered saint, also known as Thecla the Protomartyr, is shown accompanied by St Menas, whose tomb in Egypt was the pilgrimage centre associated with healing miracles. The saintly couple appear in ad bestias compositions or in a simplified variant as two saints with a cross. Although the popularity of Sts Menas and Thecla, as well as their shrines, is well known in Late Antiquity, the connection between the two cults seems to be insufficiently analysed. By means of comparing and analysing hagiographic texts, epigraphic material and objects of visual culture that depict Menas and Thecla, the paper debates the nature and origin of this cult community, aspects of pilgrimage related to the saints, as well as the iconographic patterns on which the common image of the saintly couple is based.
