To improve the outcomes of current treatments for stuttering, researchers are looking at additional tools such as transcranial Direct Current Stimulation (tDCS). The purpose of this paper is to review the literature investigating the effectiveness of tDCS for people who stutter (PWS) and offer some directions for future research. To achieve the objective of this study, we conducted a narrative review of the existing literature. Articles were selected using these inclusion criteria: participants, tDCS protocol, control group, and primary outcomes. Our literature search was limited to studies published in English with no limits on the publication year. We only extracted data from studies that investigated the effects of tDCS on PWS. Systematic reviews, meta-analyses, and other forms of reviews regarding tDCS were not included. 101 studies were identified during the exploratory phase. Ultimately, 7 studies met our inclusion criteria. Of the included papers, five studies reported mixed effects, one study showed no effect, and one study showed positive effects of tDCS. We summarized the studies in terms of several methodological features and the observed effects from tDCS. We also used the SimNIBS software to compare the effects of different stimulation parameters on brain activity and outcomes. The studies reviewed in this study have reported a variable effectiveness of tDCS for enhancing speech fluency in PWS. As a result, it remains unclear whether tDCS is an effective tool for stuttering intervention, and the optimal stimulation parameters are not yet established. Several suggestions for future research are offered.

：Long term underground coal mining results in land subsidence and deformation above the goaf area, causing damage to agriculture and degradation of soil, it is crucial to understand the geographical variability of soil nutrients in areas affected by coal mining for effective grain production and targeted reclamation activities. This study utilizes a multi-fractal methodology to clarify the influence of coal mining subsidence on the spatial diversity of soil nutrients in coal and grain composite areas with high groundwater levels. An inquiry was conducted in five selected regions in Zhao Gu Yi Mine, located in Henan Province. In addition to the control check (CK), the selected regions located in the coal mining subsidence area included the perennial subsidence ponding (PSP), seasonal subsidence ponding (SSP), neutral zone (NZ) and horizontal deformation zone (HDZ). Parameters such as generalized dimension parameters( and ) and singularity spectrum parameters( and )were utilized to quantitatively analyze the soil nutrients. The results showed that the heterogeneity of soil organic carbon (SOC) distribution in the horizontal deformation zone increased significantly compared with other regions, and the spatial variability of SOC was dominated in the high value region of the topsoil layer. Total phosphorus (TP) showed great heterogeneity only in the surface layer of seasonal subsidence ponding and horizontal deformation zone, and TP was dominated by low value and high value respectively. Water transport made the two water-soluble nutrients, available nitrogen (AN) and available phosphorus (AP), showed strong heterogeneity in the seasonal subsidence ponding, and showed a more sensitive state in the low value area. Compared with the uncertainty of field management, coal mining subsidence did noy show significant influence on the spatial distribution of soil total nitrogen (TN). Compared with classic geostatistical methods, multi-fractal methods are better suited for evaluating the spatial variability of soil nutrients in coal mining subsidence sites. By acquiring accurate data on the variability of soil nutritional characteristics at various levels, it offers scientific, theoretical, and technical assistance for targeted and precise land reclamation plans.

Human adolescents are frequently exposed to ethanol and/or to noise, agents that put brain development at risk. As the use of animal models has been demonstrated to reproduce human findings, the aim of the present study was to investigate if two weeks of ethanol intake, with an intermediate noise exposure, can affect different hippocampal-related behaviors in adolescent rats of both sexes. In addition, the enriched environment was used as an environmental housing strategy to prevent hippocampal-related behavioral changes. Importantly, although partial neuroprotection has been found in an animal model of brief ethanol intake, little is known about longer intake paradigms. Adolescent Wistar rats of both sexes were subjected to voluntary intermittent two-bottle choice paradigm of ethanol intake in for 2 weeks (6 sessions). A subgroup was exposed to noise for two hours after the third session. Some rats from both groups were housed in enriched environment cages. Finally, an assessment of hippocampal-related behaviors was performed. Data show different alterations in hippocampal-related behaviors, some of which were sex-specific and differ from those observed after a brief ethanol consumption. Most behavioral changes were prevented, at least partially, by enriched environment. These findings suggest that common environmental factors present in human adolescent venues may influence behavior that differs among sexes, as observed in the present animal model of extended ethanol intake. Additionally, an enriched environment proved to be a partially effective neuroprotective strategy in both sexes. Thus, implementation of non-pharmacological approaches may provide benefits against various challenges.

Neural development begins in gestation and continues throughout early life. The environmental effect of infant diet is a subject of increasing study as it is the caloric fuel which supports all developmental processes. Previous research in our group has found small but significant effects of nutrition on early cognitive developmental tests between children primarily fed human milk (BF), soy-based formula (SF), and dairy-based formula (MF) for the first 12 months of life. This investigation uses this same dataset: a study throughout infancy from 2 to 12 months of life. High-density electroencephalographic (EEG) recordings were taken at 2, 3, 4, 5, 6, 9, and 12 months of age using a five-minute silent video baseline. Using Specparam (formerly fitting oscillations and one-over-F or “FOOOF”), aperiodic activity was computed through a power spectral density (PSD) analysis for each session, which were then averaged per dietary group over left, right, and medial frontal and parietal regions of interest (ROIs) and one occipital ROI. Aperiodic activity is a potential marker of neuromaturation, as it is hypothesized to relate to excitatory/inhibitory (E/I) balance and structural development in GABAergic systems. Consistent with previous findings, the aperiodic exponent steadily decreased for the first five months before stabilizing. We found that this effect was largely independent of early infant diet.

Background Anaphylaxis is a severe allergic reaction with diverse clinical presentations. Identifying symptom patterns based on allergen molecules and age could improve diagnosis and management. This study assessed anaphylaxis manifestations in children, focusing on the impact of allergen molecules and age on symptom distribution. Methods A retrospective analysis was conducted on 185 pediatric patients (0–18 years) hospitalized for anaphylaxis between 2020 and 2024. Molecular allergen-specific IgE profiles were determined using the ALEX 2 test. Symptom frequencies across different organ systems were analyzed in relation to allergen molecules and age groups. Statistical analyses included Cochran’s Q test and Pearson’s χ 2 test with post-hoc adjustments. Results The most frequent molecular triggers were Ara h 2 (18.79%), Gal d 1 (9.09%), and Ana o 3 (9.09%). Significant differences in symptom distribution were observed within individual allergen molecules (p < 0.05), but no molecule-specific symptom pattern was identified. Age influenced respiratory symptom prevalence, with significant differences between infants and older children (p = 0.003). For the gastrointestinal system, results suggest the potential presence of differences that may not be detectable due to sample size limitations (p=0.051). Cardiovascular symptom differences by allergen type and age were suggested but not statistically confirmed. Conclusions Anaphylaxis symptom profiles vary across organ systems but do not show clear molecule-specific patterns. However, age-related differences in respiratory symptoms suggest that age is a relevant factor in anaphylaxis presentation. Larger studies are needed to confirm potential associations between allergen molecules, age, and symptom distribution.

Galactic rotation curve discrepancies are typically attributed to dark matter or modified gravity. This paper proposes an alternative candidate: a relativistic observational effect causing apparent galactic compression, rooted in the hypothesis that gravity arises from spacetime flow dynamics. Using an inverse problem approach, this study demonstrates that Newtonian dynamics can be reconciled with observed galactic rotation curves by incorporating a space scale factor, which accounts for relativistic observational effects. The analysis of 175 SPARC galaxies reveals a significant correlation between the proposed effect curvature and the Ricci curvature. This supports the hypothesized relativistic observational effect and reinforces the idea that general relativity remains a consistent and unified framework for understanding gravitational phenomena. All results and code associated with this study are available for review and further analysis.

Aim: Efforts to mitigate underreporting have focused on the ability of different methods, independent of spontaneous reporting, to identify ADRs. However, there is limited data on the effectiveness of these methods in detecting ADRs of interest. In this study, we collected data on this issue using the ICD-10 codes we routinely employ to detect unreported ADRs. Methods: We defined ADRs of interest as those that were severe, involved biological agents or drugs under additional monitoring, affected a child, and were previously unknown, while providing sufficient data on both the reaction and the drug. We generated a list of all patients whose discharge reports included any of the selected codes. The medical records of these patients were manually reviewed to verify the presence of an ADR and determine whether it met the criteria for being of interest. Results: We observed a significant difference between a code’s ability to detect ADRs and its effectiveness in identifying ADRs of interest. Of the 50 codes analysed, 17 were useful in identifying ADRs of interest. Conclusions: There isn‘t a small set of codes that allow to identify interesting ADRs nor any ADR related code identifies an interesting ADR every time it appears. Every unit going to use this method to identify ADRs should previously explore the utility of each code, although the codes proposed by us seems to be a good starting point.

Early and accurate detection of distributed bearing faults is critical for preventing equipment failures and minimizing downtime in industrial environments. This study explores the optimal selection of input signal sources for high-accuracy distributed fault classification, employing wavelet transform and machine learning algorithms. We utilize a comprehensive dataset encompassing three-axis vibration, stray magnetic flux, and two-phase current signals to diagnose six distinct bearing fault conditions. Wavelet transform is applied to extract frequency-domain features, capturing intricate fault signatures. To identify the most effective input signal combinations, we systematically evaluate Random Forest, XGBoost, and Support Vector Machine (SVM) models. Our analysis reveals that specific signal pairs significantly enhance classification accuracy. Notably, combining vibration signals and stray magnetic flux consistently achieves the highest performance across models, with Random Forest reaching perfect 100% test accuracy and SVM demonstrating robust performance. These findings underscore the importance of optimal source selection and the effectiveness of wavelet-transformed features for improved machine learning model performance in fault classification tasks, contributing to more reliable and cost-effective predictive maintenance systems for industrial machinery.

Species occurrence data form the basis of the establishing Species Distribution Models (SDMs). As a new technology, environmental DNA (eDNA) has been widely used for species monitoring and species diversity assessment, but it is still unclear whether it can replace or supply traditional trawl surveys to provide occurrence data for SDMs. This study took a bifurcated estuary with seawater flow backward phenomenon - the Yangtze River estuary as the research area, and the typical marine benthos - Collichthys lucidus as the research object, we carried out a comparative survey during two trips in August and November 2021, aiming to use trawl-survey data as the control group to assess the results of habitat modeling using eDNA data alone or in combination. The results showed that the trawl surveys indicated that C. lucidus inhabited almost exclusively the nearshore waters of estuaries with high salinity, which is consistent with the traditional perception that it does not inhabit freshwater (i.e. marine species). However, eDNA sampling suggested that this species was also widely distributed in the freshwater rivers of the south branch of the Yangtze River, which is likely a result of seawater intrusion from the north branch. Consequently, the Maximum Entropy Model (MaxEnt) predictions based on eDNA expanded the suitable habitat range of C. lucidus in the estuarine area. Moreover, imprecise spatial information affects the identification of key environmental requirements, underestimating the importance of salinity in habitat selection for C. lucidus. Our study highlights that in highly dynamic and open water environments like estuaries, cautious evaluation is necessary when using eDNA as species occurrence data for prediction with spatially explicit models requiring precise spatial information.

This study examines the gut microbiome from fecal samples of a reptilian model (Sceloporus undulatus). Vertebrates display a diverse range of variability in gut microbiota. The dynamic host-symbiote interactions between gut microbiota are essential in various metabolic processes and overall health of the host organism. We used 16S rRNA gene sequencing to profile the bacterial community from the guts of wild Eastern Fence Lizards. Microbiome profiles were collected at four distinct time points when lizards were actively foraging in the environment and across four age groups, aiming to characterize the natural variation in bacterial diversity among wild specimens. Bioinformatic analysis was conducted using QIIME2/DADA2 pipelines. Successional changes in the gut microbiome of lizards from the juvenile stage to adulthood revealed a pattern of increased functionality and diversity. Environmental bacteria such as Mycobacterium and Pantoea in young of year (YOY) lizards underwent successional microbiome changes to taxa including Caproiciproducens, Eubacterium, Fusobacterium, and Roseburia in adults, reflecting dietary shifts from maternal nutrients and early-stage prey to fiber-rich arthropod diets. Juvenile lizards exhibited a simple gut microbiome dominated by pioneer colonizers (Firmicutes, Bacteroidota, and Proteobacteria), with alpha diversity increasing rapidly within a month to near adult-levels. This research extends our understanding of reptilian microbiomes, capturing a snapshot of the ecological complexities of Eastern Fence Lizard microbiomes.

In this paper, we report the investigation of the thermal enhancement and the behavior of GaN Schottky diodes grown by metal organic chemical vapor deposition (MOCVD) on sapphire substrates for RF power applications and their potential to operate under extreme temperature. The Schottky barrier diodes show a Schottky barrier height (ϕB) close to 0.93 eV and an ideality factor (η) near unity with 1.03. Pt/Au anodes annealed at 500°C and 600ºC show an improvement of the electrical characteristics and a breakdown voltage as high as 130 V for a drift layer thickness of 1 µm and doping of 10^16 cm-3.

Objective: Data concerning effect on early postoperative pain and patient satisfaction after laparoscopic sacrocolpopexy (LSC) is lacking. Design: Double-blind randomized controlled trial Setting: Tertiary urogynaecology care centre, Faculty of Medicine in Pilsen, Charles University Population: Women undergoing LSC for stage > 2 pelvic organ prolapse were included. The exclusion criteria were concomitant vaginal surgery including suburethral sling or where vagina was opened during the surgery (including hysterectomy). Women with lost or incompletely filled-in McGill pain questionnaire were additionally excluded from the postoperative pain and satisfaction analysis. Methods: Women were randomized to vaginal packing after LSC with a sterile gauze. The subjective perceptions of pain were measured using McGIll Pain Questionnaire on day one before pack extraction and satisfaction was assessed using VAS on postoperative day 1 and 4. Main outcome measures: Postoperative pain on day after the surgery, patient satisfaction with the surgery and postoperative course on day one and four. Results: In total, 274 women were included in analysis, vaginal pack was inserted in 132 (48%) women. The groups did not differ in basic preoperative nor surgical characteristics. Very low and comparable values of all scores of the McGill Pain Questionnaire were observed (VAS pain 3.2 ±1.8 vs. 3.4±1.9, p=0.330). No difference in patient satisfaction on day one (7.3±1.8 vs. 7.4±1.7, p=0.633) nor overall satisfaction on day 5 (8.7±1.3 vs. 8.8±1.1,p=0.719) was observed. Conclusion: Laparoscopic sacrocolpopexy is associated with low levels of pain and high patient satisfaction regardless of vaginal pack insertion. Vaginal packing does not harm the patients.

Southern Ocean plankton dynamics are climate-sensitive. Using CMIP6 multi-model ensemble projections, we find that the seemingly stable Southern Ocean plankton biomass under climate change masks opposing trends across different geographic zones. Plankton in the subpolar zone is projected to remain relatively stable due to compensatory changes in bottom-up and top-down processes. Plankton in the subtropical and seasonal ice zones are projected to experience negative and positive trophic amplification, respectively, with zooplankton decreasing and increasing proportionally more than phytoplankton. The predicted trophic amplification arises from uneven seasonal changes in zooplankton grazing, driven by changes in phytoplankton. The negative trophic amplification in the subtropical zone primarily originates during the shallow mixed-layer period, where further shoaling of the mixed layer in the changing climate accentuates nutrient limitation. The consequent reduction in phytoplankton growth and concentration leads to a disproportionate decline in zooplankton grazing and biomass. The positive trophic amplification in the seasonal ice zone also occurs mainly during the shallow mixed-layer season. Improved light availability due to shoaling of the relatively deep mixed layer, sea ice retreat, and warmer temperatures boost phytoplankton growth, together with further suppressing surface phytoplankton, resulting in a disproportionate increase in zooplankton grazing and biomass. Our results underscore the importance of assessing seasonal and regional variations in plankton dynamics to unveil the nuanced effects of climate change on marine plankton ecosystems.

To mitigate the adverse effects of climate change, development of stress-resilient crops has assumed widespread significance. Though, the dehydration-responsive element binding protein (DREB) transcription factors have been demonstrated to be crucial for stress tolerance in model plants, their role in economically important crops largely remain unclear. In the present study, the role of MusaDREB1G in overcoming drought or cold tolerance was investigated in banana, a plant that is vital for global agriculture and food security. Stress profiling revealed transcription of MusaDREB1G to alter in response to with drought, cold, salinity, or ABA exposures, which was corroborated with stress-induced activation of Pro MusaDREB1G-GUS. Pro MusaDREB1G, which harbors various-stress-associated cis-elements, was primarily active in vascular tissues under control growth conditions. Interestingly, in response to drought, salinity, or cold, the Pro MusaDREB1G was also activated in non-vascular tissues. Overexpression of MusaDREB1G led to a dwarf phenotype, but surprisingly these banana lines showed improved drought or cold tolerance. The overexpression line was characterized in detail to obtain mechanistic insights into this phenomenon. Results showed a distinct elevation in abscisic acid (ABA) and jasmonic acid (JA) content, which correlated well with enhanced expression of stress-related genes in transgenic lines. These findings unveil a novel MusaDREB1G-driven common mechanism for cold/drought tolerance and paves the way for engineering stress-resistant banana crops using MusaDREB1G.

Title: A Rare Clinical Scenario of papillary renal cell carcinoma type 2

IntroductionNeonatal pustular eruptions encompass a group of disorders characterized by various forms of pustulosis occurring within the first four weeks of life. The differential diagnosis for these eruptions can be quite extensive, presenting significant diagnostic challenges even for experienced physicians. It is critical to consider potentially life-threatening conditions, such as herpes simplex virus infections, among the infectious causes. Among non-infectious entities, erythema toxicum neonatorum, transient neonatal pustular melanosis, and miliaria pustulosa are the most common.Knowing the typical and less common clinical presentation, diagnostic criteria, can aid in making the correct diagnosis and avoid unnecessary investigations and referrals.

Case Report

The electrochemical CO 2 reduction reaction is crucial for reducing atmospheric CO 2 and achieving carbon neutrality. Recent researches have predominantly focused on the development of high-performance catalysts, evaluating their performance remains time-consuming. Concurrently, in situ spectroscopic techniques have been instrumental in elucidating catalytic mechanisms and fundamental reaction pathways. In this study, we employ constant potential ab initio molecular dynamics simulations to precisely model the adsorption behavior of CO 2 molecules on Cu-Ag alloy surfaces, with a particular focus on tracking variations in the bond angles of the adsorbed CO 2. By generating 2600 unique spectral datasets, we leverage convolutional neural networks to extract key spectral features and train a deep learning model to predict the bond angles of adsorbed CO 2 based on the corresponding spectral information. Given that the bond angle of adsorbed CO 2 serves as a crucial descriptor of a catalyst’s ability to activate CO 2 molecules, our approach demonstrates the efficacy of AI in predicting catalytic activity. Furthermore, we extend this model’s applicability to Cu-Au and Cu-Zn alloys, establishing the potential for AI-driven preliminary catalyst screening based on spectral data. This methodology has the capacity to significantly accelerate the catalyst development pipeline by reducing the reliance on analyzing conventional experimental results manually.

Background: Foreign body (FB) aspiration is a typical emergency experienced by young children and associated with significant morbidity and mortality unless diagnosed early and treated adequately. Data on anesthetic management, applicability, complications and risk factors in the context of foreign body removal (FBR) is scarce, especially for flexible techniques, which are increasingly being used. Aim: To analyze the complication rate and risk factors as well as the anesthetic management of two different techniques (rigid versus flexible) for FBR in children. Method: This is a retrospective single center analysis of 160 cases who underwent bronchoscopy for suspected FB aspiration under general anesthesia between January 2014 and January 2022 at a tertiary hospital. Results: An FB was detected in 67 patients (median age 1.8 years). The preferred anesthesia regimes were total intravenous anesthesia (91.9%) and laryngeal mask (95%) for flexible bronchoscopy. Flexible bronchoscopy was used in 52.2%, rigid bronchoscopy in 31.3%, and both techniques were used in 16.4% of cases. The complication rate was 2.19 vs. 1.29/patient in rigid vs. flexible bronchoscopy, respectively. Independent risk factors for severe complications were rigid bronchoscopy (OR 11.6, p<0.01) and airway infections (OR 4.1, p<0.01). We observed flexible bronchoscopy being increasingly used for FBR during the observational period. Conclusion: FBR can result in serious complications that require experienced pediatric anesthetic management. In our series, the use of a rigid bronchoscope and preexisting airway infection were independent risk factors for severe complications. Flexible bronchoscopy was shown to be a safe, fast and successful tool for FBR with fewer adverse events compared to rigid bronchoscopy. Total intravenous anesthesia and a laryngeal mask airway for FBR are feasible and safe.

A visible-light photoredox-catalyzed difunctionalization of diazomethyl radicals with two heteroatomic nucleophiles (saturated bonds) generated in situ from the reaction of secondary amines with CS 2 or CO 2 has been developed for the first time. This reaction provides a new and modular approach for the synthesis of valuable but difficultly accessible S-alkyl di-dithiocarbamates and O-alkyl di-carbamates from readily available starting materials in a single step.

We establish a rigorous proof of the Riemann Hypothesis (RH), which asserts that all non-trivial zeros of the Riemann zeta function lie on the critical line \( (s) = {2} \). This proof synthesizes: (1) analytic number theory via logarithmic derivatives, (2) prime distribution analysis using Weil’s explicit formula, and (3) functional space spectral density using Beurling-Nyman’s criterion. By deriving explicit contradictions for any off-critical zero, we resolve RH formally.

Introduction: The ablation index (AI) standardizes lesions in radiofreqency ablation (RF) of atrial fibrillation (AF). High-power, short-duration ablation (HPSD) shortens procedures, but AI is histologically unvalidated in HPSD. We evaluated esophageal safety with voltage-adapted AF ablation using an optimized, AI-guided HPSD (AI-HPSD) protocol. Methods: Consecutive AF patients undergoing AI-HPSD at 50W (AI=400-450 for posterior left atrium (LA); AI ≥500 anteriorly) were compared with a recent AF cohort who underwent AI-guided low-power, long-duration ablation (AI-LPLD). All participated in our ablation registry. Esophageal endoscopy was performed 1-3 days post-ablation. Posterior wall lesion characteristics and endoscopically-detected esophageal lesions (EDEL) were compared. Results: AI-LPLD (n=100) and AI-HPSD (n=100) groups had similar baselines, except AI-LPLD had slightly larger LA-area. VISITAG numbers were comparable, but total posterior wall RF time was shorter with AI-HPSD versus AI-LPLD (4.5±1.6 versus 11.9±5.1 s, p<0.001). Mean AI and mean impedance drop were higher in AI-HPSD (449±17 versus 401±39; p<0.001 and 8.8±2.3 versus 7.8±2.5; p<0.001). AI standard deviation was lower with AI-HPSD (30±15 versus 49±19; p<0.001). Although Max AI values were higher in AI-HPSD (517±46 versus 496±55; p=0.003), maximum impedance drop did not differ significantly. EDEL rate was comparably low at 2% (AI-HPSD) and 4% (AI-LPLD), but Max AI >520 occurred more with AI-HPSD (3.5±5.5 versus 2.5±5.2; p=0.048). Conclusion: In routine practice, optimized AI-HPSD at 50W with posterior LA target AI =400-450 was not associated with more EDEL. However, a signal for more unacceptable Max AI values existed. We recommend limiting AI to 400 and developing an automatic, AI-guided ablation stop.
