Combined use of isotopic and hydrometric data to conceptualize ecohydrological processes in a high‐elevation tropical ecosystem

Few high‐elevation tropical catchments worldwide are gauged, and even fewer are studied using combined hydrometric and isotopic data. Consequently, we lack information needed to understand processes governing rainfall–runoff dynamics and to predict their influence on downstream ecosystem functioning. To address this need, we present a combination of hydrometric and water stable isotopic observations in the wet Andean páramo ecosystem of the Zhurucay Ecohydrological Observatory (7.53 km2). The catchment is located in the Andes of south Ecuador between 3400 and 3900 m a.s. l. Water samples for stable isotopic analysis were collected during 2 years (May 2011–May 2013), while rainfall and runoff measurements were continuously recorded since late 2010. The isotopic data reveal that andosol soils predominantly situated on hillslopes drain laterally to histosols (Andean páramo wetlands) mainly located at the valley bottom. Histosols, in turn, feed water to creeks and small rivers throughout the year, establishing hydrologic connectivity between wetlands and the drainage network. Runoff is primarily composed of pre‐event water stored in the histosols, which is replenished by rainfall that infiltrates through the andosols. Contributions from the mineral horizon and the top of the fractured bedrock are small and only seem to influence discharge in small catchments during low flow generation (non‐exceedance flows < Q35). Variations in source contributions are controlled by antecedent soil moisture, rainfall intensity, and duration of rainy periods. Saturated hydraulic conductivity of the soils, higher than the year‐round low precipitation intensity, indicates that Hortonian overland flow rarely occurs during high‐intensity precipitation events. Deep groundwater contributions to discharge seem to be minimal. These results suggest that, in this high‐elevation tropical ecosystem, (1) subsurface flow is a dominant hydrological process and (2) (histosols) wetlands are the major source of stream runoff. Our study highlights that detailed isotopic characterization during short time periods provides valuable information about ecohydrological processes in regions where very few basins are gauged.

Advancing precision in histocompatibility and immunogenetics: a comprehensive review of the UCLA exchange program

Precise typing of human leukocyte antigens (HLA) is crucial for clinical hematopoietic stem cell and solid organ transplantations, transfusion medicine, HLA-related disease association, and drug hypersensitivity analysis. The UCLA Cell Exchange program has played a vital role in providing educational and proficiency testing surveys to HLA laboratories worldwide for the past 5 decades. This article highlights the significant contribution of the UCLA Cell and DNA Exchange Programs in advancing HLA antibody testing, genotyping, crossmatches, and, more recently, virtual crossmatches. Additionally, we discuss future directions of the UCLA Cell Exchange program to support histocompatibility testing to adapt to the fast-evolving field of immunotherapy, tolerance and xenotransplantation.
STRUCTURE IN PRIMARY SONG OF THE MOCKINGBIRD (MIMUS POLYGLOTTOS)

MOST of what has been written about the song of the Mockingbird has been concerned with interspecific mimicry (Whittle, 1922; Visscher, 1928; Mayfield, 1934; Bent, 1948; Bedichek, 1947) or with various aspects of the song in relation to ontogenetic and behavioral phenomena in addition to mimicry (Laskey, 1935, 1944; Michener and Michener, 1935). The present study presents a quantitative description of certain aspects of primary or advertising song of male Mockingbirds on territory in spring and early summer. Tentative suggestions concerning the significance and function of various parameters of the song are included.
Assessment of Antimicrobial Activity of Nanocomposites Based on Nano-Hydroxyapatite (HAP), Chitosan, and Vitamin K2

Objective: The objective of this study was to evaluate the antimicrobial potential of nanocomposites containing vitamin K2, hydroxyapatite nanoparticles (nHAP), and chitosan (Chito)-coated dental implants against clinically relevant microbial strains. Materials and Methods: Four test compounds were prepared: vitamin K2 + nHAP, K2 + Chito + nHAP, vitamin K2, and vitamin K2 + Chito. Agar well diffusion test was conducted to assess the antimicrobial activity of these compounds against Staphylococcus aureus (S. aureus), Streptococcus mutans (S. mutans), Enterococcus faecalis (E. faecalis), and Candida albicans (C. albicans). Results: The vitamin K2 + nHAP nanocomposite exhibited antimicrobial activity against all tested microorganisms, with E. faecalis showing the highest sensitivity (25 mm zone of inhibition at 100 µL concentration). The K2 + Chito + nHAP nanocomposite demonstrated potent antimicrobial activity with C. albicans displaying the highest sensitivity (28 mm zone of inhibition at 100 µL concentration). Pure vitamin K2 showed limited antimicrobial activity, vitamin K2 combined with chitosan exhibited significant susceptibility to C. albicans, resulting in a substantial inhibition zone of 24 mm diameter at a concentration of 100 µL. Conclusion: The synergistic effects of vitamin K2 with nHAP and chitosan highlight the potential of these nanocomposites for biomedical applications. These findings contribute to the development of effective nanocomposites to address antimicrobial resistance and improve infection control in various biomedical fields.
Interventricular Septal Hematoma Complicating Left Bundle Branch Area Pacing: A Case Report—The Devil Is Not So Black as He Is Painted

Background: This case report outlines the presentation of an emerging complication arising from left bundle branch area pacing (LBBAP). Case summary: A 43-year-old male with no history of cardiac problems experienced recurrent episodes of syncope with no prodromal symptoms. During monitoring in the emergency department, the patient underwent an episode of asystole, leading to LBBAP implantation. The procedure encountered technical challenges, resulting in an interventricular septal hematoma and subsequent ventricular arrhythmias. Despite initial concerns, conservative management led to resolution, demonstrated through echocardiographic follow-ups. Discussion: This report underscores the significance of ventricular arrhythmias as indicators of interventricular septal hematoma, providing insights into its diagnosis, management, and implications for LBBAP procedures.
On the Advantages of Using a Strict Hierarchy to Model Astrodynamical Problems

In this paper an algorithm is developed that combines the capabilities and advantages of several different astrodynamical models of increasing complexity. Splitting these models in a strict hierarchical order yields a clearer grasp on what is available. With the effort of developing a comprehensive model overhead, the equations for the spacecraft motion in simpler models can be readily obtained as particular cases. The proposed algorithm embeds the circular and elliptic restricted three-body problems, the four-body bicircular and concentric models, an averaged n-body model, and, at the top hierarchic ladder, the full ephemeris spice-based restricted n-body problem. The equations of motion are reduced to the assignment of 13 time-varying coefficients, which multiply the states and the gravitational potential to reproduce the proper vector field. This approach is powerful because it allows, for instance, an efficient and quick way to check solutions for different dynamics and parameters. It is shown how a gradual increase of the dynamics complexity greatly improves accuracy, the chances of success and the convergence rate of a continuation algorithm, applied to low-energy transfers.
Label-Free Liquid Chromatography–Mass Spectrometry Quantitation of Relative N- and O-Glycan Concentrations in Human Milk in Japan

Human milk is abundant in carbohydrates and includes human milk oligosaccharides (HMOs) and N/O-glycans conjugated to proteins. HMO compositions and concentrations vary in individuals according to the maternal secretor status based on the fucosyltransferase 2 genotype; however, the profile of N/O-glycans remains uninvestigated because of the analytical complexity. Herein, we applied a label-free chromatography–mass spectrometry (LC–MS) technique to elucidate the variation in the composition and concentration of N/O-glycans in human milk. We used label-free LC–MS to relatively quantify 16 N-glycans and 12 O-glycans in 200 samples of Japanese human milk (1–2 months postpartum) and applied high performance anion exchange chromatography with pulsed amperometric detection to absolutely quantify the concentrations of 11 representative HMOs. Cluster analysis of the quantitative data revealed that O-glycans and several HMOs were classified according to the presence or absence of fucose linked to galactose while N-glycans were classified into a different group from O-glycans and HMOs. O-glycans and HMOs with fucose linked to galactose were more abundant in human milk from secretor mothers than from nonsecretor mothers. Thus, secretor status influenced the composition and concentration of HMOs and O-glycans but not those of N-glycans in human milk.
Association of structural connectivity with functional brain network segregation in a middle-aged to elderly population

Introduction The deterioration of white matter pathways is one of the hallmarks of the ageing brain. In theory, this decrease in structural integrity leads to disconnection between regions of brain networks and thus to altered functional connectivity and a decrease in cognitive abilities. However, in many studies, associations between structural and functional connectivity are rather weak or not observed at all. System segregation, defined as the extent of partitioning between different resting state networks has increasingly gained attention in recent years as a new metric for functional changes in the aging brain. Yet there is a shortage of previous reports describing the association of structural integrity and functional segregation. Methods Therefore, we used a large a large sample of 2,657 participants from the Hamburg City Health Study, a prospective population-based study including participants aged 46–78 years from the metropolitan region Hamburg, Germany. We reconstructed structural and functional connectomes to analyze whether there is an association between age-related differences in structural connectivity and functional segregation, and whether this association is stronger than between structural connectivity and functional connectivity. In a second step, we investigated the relationship between functional segregation and executive cognitive function and tested whether this association is stronger than that between functional connectivity and executive cognitive function. Results We found a significant age-independent association between decreasing structural connectivity and decreasing functional segregation across the brain. In addition, decreasing functional segregation showed an association with decreasing executive cognitive function. On the contrary, no such association was observed between functional connectivity and structural connectivity or executive function. Discussion These results indicate that the segregation metric is a more sensitive biomarker of cognitive ageing than functional connectivity at the global level and offers a unique and more complementary network-based explanation.
The Effectiveness of Combined Exercise and Self-Determination Theory Programmes on Chronic Low Back Pain: A Systematic Review and Metanalysis

Low back pain is a pervasive issue worldwide, having considerable prevalence and a significant impact on disability. As low back pain is a complicated condition with many potential contributors, the use of therapeutic exercise, combined with other techniques such as self-determination theory programmes, has the potential to improve several outcomes. The aim of this systematic review was to explore the effectiveness of combined exercise and self-determination theory programmes on chronic low back pain. This study was designed according to Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines. A systematic search in three databases (PubMed/MEDLINE, Web of Science, and Scopus) was conducted from September to November 2023. After screening, a total of five random control trials with patients with chronic low back pain were included in this systematic review and meta-analysis. The results showed significant differences in disability (SMD = −0.98; 95% CI = −1.86, −0.09; p = 0.03) and in quality of life (SMD = 0.23; 95% CI = 0.02, 0.44; p = 0.03) in favour of the intervention group versus the control group.
Polyelectrolyte–Surfactant Complex Nanofibrous Membranes for Antibacterial Applications

Polyelectrolyte–surfactant complexes (PESCs) have garnered significant attention due to their extensive range of biological and industrial applications. Most present applications are predominantly used in liquid or emulsion states, which limits their efficacy in solid material-based applications. Herein, pre-hydrolyzed polyacrylonitrile (HPAN) and quaternary ammonium salts (QAS) are employed to produce PESC electrospun membranes via electrospinning. The formation process of PESCs in a solution is observed. The results show that the degree of PAN hydrolysis and the varying alkyl chain lengths of surfactants affect the rate of PESC formation. Moreover, PESCs/PCL hybrid electrospun membranes are fabricated, and their antibacterial activities against both Gram-negative Escherichia coli (E. coli) and Gram-positive Staphylococcus aureus (S. aureus) are investigated. The resulting electrospun membranes exhibit high bactericidal efficacy, which enables them to serve as candidates for future biomedical and filtration applications.
Novel Therapeutic Targets on the Horizon: An Analysis of Clinical Trials on Therapies for Bone Metastasis in Prostate Cancer

Simple Summary Prostate cancer is the most common non-cutaneous malignancy among men in the United States. Bone metastases and health are crucial issues in prostate cancer patient management. The aim of our review was to summarize the novel therapeutic targets of prostate cancer with bone metastasis, including treatments to palliate pain and therapies to prevent complications of osseous metastasis. Additionally, our study offers a comprehensive overview of the research on bone metastases in prostate cancer, which can be a valuable resource for researchers in the field. Abstract In the absence of early detection and initial treatment, prostate cancer often progresses to an advanced stage, frequently spreading to the bones and significantly impacting patients’ well-being and healthcare resources. Therefore, managing patients with prostate cancer that has spread to the bones often involves using bone-targeted medications like bisphosphonates and denosumab to enhance bone structure and minimize skeletal complications. Additionally, researchers are studying the tumor microenvironment and biomarkers to understand the mechanisms and potential treatment targets for bone metastases in prostate cancer. A literature search was conducted to identify clinical studies from 2013 to 2023 that focused on pain, performance status, or quality of life as primary outcomes. The analysis included details such as patient recruitment, prior palliative therapies, baseline characteristics, follow-up, and outcome reporting. The goal was to highlight the advancements and trends in bone metastasis research in prostate cancer over the past decade, with the aim of developing strategies to prevent and treat bone metastases and improve the quality of life and survival rates for prostate cancer patients.
Caractérisation d'un bassin d'avant-pays dans le Carbonifère des Pyrénées : faciès, chronologie de la tectonique synsédimentaire

A foreland basin has been characterized in the pre-Stephanian Carboniferous series of the Pyrenees. The carbonate series, where storm deposits have been recognixed in the «Calcaires a laminites» Formation, correspond to a platform retrograding towards the south-west. The Culm is interpreted as a syntectonic turbidite series including channelized siliciclastic systems and slope-apron carbonate systems fed by the collapse of platforms which were established on a northeastern orogenic margin. The diachronism of the carbonates-Culm boundary indicates the migration of the orogenesis from Late Visean to Westphalian
Postoperative intensity-modulated radiation therapy provides favorable local control and low toxicities in patients with soft tissue sarcomas in the extremities and trunk wall

Purpose To investigate the efficacy and toxicity of postoperative intensity-modulated radiation therapy (IMRT) for patients with soft tissue sarcomas (STSs) in the extremities and trunk wall. Patients and methods Eighty patients with localized STSs in the extremities and trunk wall treated with function-conserving surgery and postoperative IMRT were analyzed. The primary locations were in the extremities in 51 patients and in the trunk wall in 29 patients. The margins were positive in nine patients and negative in 71 patients. The median dose of IMRT was 64 Gy. Results At a median follow-up time of 38 months, eight patients developed local recurrences. The 5-year local control (LC) rate was 88.1%. The patients with negative margins exhibited much better LC than did those with positive margins (90% vs 64.8%, P=0.023). Multivariate analysis revealed that positive margin was an independent risk factor for LC. The 5-year distant metastasis-free survival, disease-free survival, and overall survival rates were 75.2%, 72.6%, and 83.6%, respectively. Large tumor size (>5 cm) was significantly associated with poor overall survival. Edema and joint stiffness were observed in 17.6% and 9.8% of patients with extremity STSs, respectively. Conclusion IMRT provides excellent LC and low toxicity for patients with STSs in the extremities and trunk wall.
Protocol for Cerebellar Stimulation for Aphasia Rehabilitation (CeSAR): A randomized, double-blind, sham-controlled trial

In this randomized, double-blind, sham-controlled trial of Cerebellar Stimulation for Aphasia Rehabilitation (CeSAR), we will determine the effectiveness of cathodal tDCS (transcranial direct current stimulation) to the right cerebellum for the treatment of chronic aphasia (>6 months post stroke). We will test the hypothesis that cerebellar tDCS in combination with an evidenced-based anomia treatment (semantic feature analysis, SFA) will be associated with greater improvement in naming untrained pictures (as measured by the change in Philadelphia Picture Naming Test), 1-week post treatment, compared to sham plus SFA. We will also evaluate the effects of cerebellar tDCS on naming trained items as well as the effects on functional communication, content, efficiency, and word-retrieval of picture description, and quality of life. Finally, we will identify imaging and linguistic biomarkers to determine the characteristics of stroke patients that benefit from cerebellar tDCS and SFA treatment. We expect to enroll 60 participants over five years. Participants will receive 15, 25-minute sessions of cerebellar tDCS (3-5 sessions per week) or sham tDCS combined with 1 hour of SFA treatment. Participants will be evaluated prior to the start of treatment, one-week post-treatment, 1-, 3-, and 6-months post treatment on primary and secondary outcome variables. The long-term aim of this study is to provide the basis for a Phase III randomized controlled trial of cerebellar tDCS vs sham with concurrent language therapy for treatment of chronic aphasia.
The impact of social hierarchies on neural response to feedback evaluations after advice giving

Abstract Advisors generally evaluate advisee‐relevant feedback after advice giving. The response to these feedback—(1) whether the advice is accepted and (2) whether the advice is optimal—usually involves prestige. Prior literature has found that prestige is the basis by which individuals attain a superior status in the social hierarchy. However, whether advisors are motivated to attain a superior status when engaging in advice giving remains uncharacterized. Using event‐related potentials, this study investigates how advisors evaluate feedback after giving advice to superior (vs. inferior) status advisees. A social hierarchy was first established based on two advisees (one was ranked as superior status and another as inferior status) as well as participants' performance in a dot‐estimation task in which all participants were ranked as medium status. Participants then engaged in a game in which they were assigned roles as advisors to a superior or inferior status advisee. Afterward, the participants received feedback in two phases. In Phase 1, participants were told whether the advisees accepted the advice provided. In Phase 2, the participants were informed whether the advice they provided was correct. In these two phases, when the advisee was of superior status, participants exhibited stronger feedback‐related negativity and P300 difference in response to (1) whether their advice was accepted, and (2) whether their advice was correct. Moreover, the P300 was notably larger when the participants' correct advice led to a gain for a superior‐status advisee. In the context of advice giving, advisors are particularly motivated to attain a superior status when the feedback involving social hierarchies, which is reflected in higher sensitivity to feedback associated with superior status advisees at earlier and later stages during feedback evaluations in brains.
Pets, furry animal allergen components, and asthma in childhood

Abstract Background The use of component‐resolved allergy diagnostics has provided a clearer understanding of the species‐specific sensitization and severity of potential allergic reactions. This cross‐sectional study aimed to determine whether sensitization to allergen components in furry animals is indicative of blood eosinophilia, a positive fractional exhaled nitric oxide (FeNO) test, abnormal lung function, and asthma symptoms in children. Additionally, we investigated whether having pets during childhood affects the development of asthma or allergic sensitization to furry animals. Methods We recruited 203 children aged 4–17 years with asthma diagnosis based on abnormal lung function and 33 controls. IgE‐sensitization to allergen components for dogs, cats, and horses was analyzed using a multiplex microarray. Children were tested with FeNO, impulse oscillometry, spirometry, methacholine challenge, and skin prick test. A questionnaire was used to investigate pet ownership and symptom profile. Results FeNO results and blood eosinophilia revealed a correlation with sensitization to all furry animal allergens, particularly lipocalins (r = 0.203–0.560 and 0.206–0.560, respectively). Can f 3 was found to correlate with baseline R5 (r = 0.298). No association between methacholine challenge results and sensitization to furry animal allergens was found. Children with asthma who were sensitized to Can f 1, Can f 6, or both frequently reported asthma symptoms. Dog ownership was associated with a lower level of IgE‐sensitization to lipocalins, fewer asthma symptoms, and less blood eosinophilia. Conclusion Furry animal allergen component IgE‐sensitization is a risk factor for type 2‐inflammation and asthma symptoms.
