BackgroundMechanical ventilation can lead to lung injury and diaphragmatic dysfunction. Rapid bilateral anterolateral magnetic phrenic nerve stimulation (rBAMPS) may attenuate both of the aforementioned issues by inducing diaphragm activation. However, in order for rBAMPS to become part of standard of care, the reliability of inspiratory responses to rBAMPS needs to be established.MethodsEighteen healthy participants (9F) underwent five blocks of 1-s rBAMPS at 25 Hz starting at 20% of maximal stimulator output with 10% increments. Three blocks were completed on the same day to test within-day reliability, and two additional blocks were each completed on subsequent days to test between-day reliability. Mean transdiaphragmatic pressure (Pdi,mean), tidal volume (VT), discomfort, pain, and paresthesia were recorded for each rBAMPS. Relative and absolute reliability of both Pdi,mean and VT were quantified by calculating intraclass correlation coefficients (ICC) and standard error of measurements (SEM), respectively. An ordinal regression was used to determine changes of sensory ratings within and between days.ResultsAt all stimulator outputs, within-day Pdi,mean displayed “good” reliability (ICC range 0.78–0.89). Between days, Pdi,mean reliability was also “good” (ICC range 0.79–0.87) at stimulator outputs of 20%–50% of maximum, but “moderate” (ICC range 0.56–0.72) at stimulator outputs of 60%–100%. SEM for Pdi,mean within day ranged from 0.9 to 3.4 across tested stimulator outputs and increased on average by 1.4 ± 0.9 between days. The VT reliability was “good” to “excellent” within (ICC range 0.82–0.94) and between (ICC range 0.81–0.96) days at all stimulator outputs. SEM for VT within day ranged from 0.08 to 0.36 and from 0.11 to 0.30 between days and tended to be larger at stimulator outputs greater than 50% of maximum. Subsequent blocks within day were associated with decreased discomfort and pain (P ≤ 0.043), while subsequent days were associated with decreased discomfort and paresthesia (P &lt; 0.001).DiscussionrBAMPS appears to induce reliable diaphragmatic contractions, while select sensory responses become blunted over repeated stimulations. However, as reliability is slightly lower between days compared to within day, stimulation parameters may need to be adjusted to achieve similar responses on different days.

IntroductionConstructed wetlands have become crucial ecosystems for the purification of industrial and agricultural water. The health of wetland plants and the efficacy of water purification are strongly influenced by root-associated bacteria. However, our understanding of the functions of bacterial communities in the plant different root components (i.e., rhizosphere, rhizoplane, and endosphere) and their impact on water purification is still limited.MethodsTo address this knowledge gap, we employed high-resolution 16S rRNA deep amplicon sequencing to explore the bacterial community structure and assembly within the root components of three plant species (i.e. Iris ensata, Canna indica, and Hymenocallis littoralis) found in constructed wetlands.ResultsOur findings revealed that the pollutant removal efficiency was higher in the wet season than in the dry season. The specific root compartment, plant species, environmental factors, and seasonality significantly influenced the bacterial composition, diversity and abundance. Across all three plant species, Proteobacteria emerged as the dominant bacterial groups in all root components. The abundance and diversity of bacterial communities exhibited a decline from the rhizosphere to the endosphere, accompanied by an increase in the number of distinctive biomarkers from the rhizosphere to the endosphere. The bacterial composition exhibited significant similarity in the rhizosphere in the dry season and the endosphere in the wet season. Bacterial genes in the rhizosphere-rhizoplane were associated with environmental information processing, transportation and metabolism, while those in the rhizoplane-endosphere primarily handle metabolic processes. The bacterial community positively correlated with total nitrogen content, chemical oxygen demand, and NO4+-N in the dry season, while associated with total phosphorus, total organic carbon, and NO3+-N content in the wet season.DiscussionThe structure and function of the bacterial community within the root rhizoplane-endosphere can serve as indicators of the water purification efficacy of constructed wetlands.

Published: February 2025

IntroductionIsochronous rhythm has been shown to induce temporal expectation, allocated attention to specific points in time to optimize behavioral performance, both within a single modality and across different modalities, in younger adults. However, it remains unclear how an isochronous rhythm in one modality influences the temporal allocation of attention in another modality among older adults. Moreover, whether the cross-modal temporal expectation effect in aging is influenced by tempo has not yet been explored.MethodsTo address these issues, both younger and older participants performed a rhythmic temporal expectation task in which auditory isochronous rhythms, presented at either 600 ms (faster) or 1,400 ms (slower) tempo, were used to trigger temporal expectation for a visual target.ResultsThe results demonstrated a cross-modal temporal expectation effect, with participants exhibiting significantly faster responses when the visual target appeared in synchrony with the preceding auditory rhythm compared to out-of-synchrony trials. This effect was evident in both younger and older groups and was not influenced by tempo.DiscussionThese findings suggest that the ability to utilize auditory isochronous rhythms to drive the temporal allocation of visual attention can be preserved in normal aging, highlighting the robustness of cross-modal temporal expectations across both younger and older adults.
Validation of the death reflection scale among older people
Authors: Richter Lukas 
Published: February 2025

BackgroundHuman beings possess the capacity to cognize their own mortality, which compels them to process death awareness. The present study seeks to validate the Death Reflection Scale (DRS) among older individuals, which measures growth-oriented cognitions and prosocial behavior following confrontation with death awareness.Materials and methodsDRS was validated using a cross-sectional online survey of older adults (50+). To assess configural, metric, and scalar measurement equivalence across age groups of older adults, a multi-group confirmatory factor analysis was conducted in conjunction with dynamic fit index cutoffs. Construct validity was evaluated using Pearson’s correlation and analysis of variance (ANOVA). The data were obtained from an online survey. The survey was conducted in May 2023 and people aged 50 and over were recruited from an online panel using quota sampling (by age, gender and federal state). A total of 1,806 individuals completed the survey.ResultsConfirmatory factor analysis showed a good fit of the originally proposed 5-factor (CFI 0.949, SRMR 0.058, RMSEA 0.070) and bi-factor model (CFI 0.956, SRMR 0.067, RMSEA 0.067) with a general factor and five subscales. In light of several considerations, it is recommended that the DRS should be considered as a five-factor model, as originally proposed. Alpha ranges from 0.807 to 0.875 and Omega from 0.811 to 0.875, indicating good reliability. Partial scalar invariance was obtained, therefore mean comparisons can be made between groups of older people. Testing the construct validity showed only a partial confirmation. The exploratory analysis of the DRS with the Big Five personality traits revealed a correlation structure that can be plausibly explained by considering the facets of personality traits.ConclusionThe value of the DRS lies in its perspective that death awareness should not only be viewed as a threat, but rather as a potential for a positive and growth-oriented perspective on death awareness and has been validated for older adults. The present study demonstrated that mean comparisons could be conducted between groups of older adults. Tests of construct validity yielded inconclusive results, indicating the necessity for further analysis.

IntroductionParents' negative parenting style is an important cause of anxiety, depression, and suicide among university students. Given the widespread use of social media, microblogs offer a new and promising way for non-invasive, large-scale assessment of parenting styles of students' parents.MethodsIn this study, we have two main objectives: (1) investigating the correlation between students' microblog discourses and parents' parenting styles and (2) devising a method to predict students' parenting styles from their microblog discourses. We analyzed 111,258 posts from 575 university students using frequency analysis to examine differences in the usage of topical and emotional word across different parenting styles. Informed by these insights, we developed an effective parenting style assessment method, including a correlation injection module.ResultsExperimental results on the 575 students show that our method outperforms all the baseline NLP methods (including ChatGPT-4), achieving good assessment performance by reducing MSE by 14% to 0.12.DiscussionOur study provides a pioneering microblog-based parenting style assessment tool and constructs a dataset, merging insights from psychology and computational science. On the one hand, our study advances the understanding of how parenting styles are reflected in the linguistic and emotional expressions of students on microblogs. On the other hand, our study provides an assisting tool that could be used by healthcare institutions to identify students' parenting styles. It facilitates the identification of suicide risk factors among microblog student users, and enables timely interventions to prevent suicides, which enhances human wellbeing and saves lives.

IntroductionAperema (Rhinoclemmys punctularia) is a South American semi-aquatic freshwater turtle characterized by a highly curved, dark brown to black carapace and is distributed across Central and South America. Climate change affects freshwater turtles in a number of ways, including temperature, hatchling sex, and survival.MethodsTherefore, we analyzed temperature variations in these turtles through electrocardiographic recordings, since studies on temperature variations in R. punctularia are limited.Results and discussionElectrocardiography (ECG) is a highly relevant diagnostic tool as it allows for precise assessments of cardiac events and is non-invasive. The development of non-invasive ECG measurement methods is crucial for evaluating and maintaining the health of chelonian individuals during veterinary treatment or experimental procedure. Our findings revealed that heart rate is temperature-dependent, showing that lower environmental temperatures result in decreased heart rates. Therefore, we demonstrated through the electrocardiographic patterns observed during the experiment that a reduction in the ambient temperature to which Rhinoclemmys punctularia are exposed can modulate the conductivity and automaticity of cardiac cells, subsequently leading to a decrease in heart rate.

IntroductionTicks are important ectoparasites of livestock. Ticks and tick-borne diseases (TBDs) cause losses to the animal husbandry industry and also present a major hidden danger to public health and safety. However, the tick species and prevalence of TBDs in border regions of China, Russia, and North Korea remain unknown. The purpose of this study was to identify the tick species and tick-borne pathogens endemic in these regions.MethodsMorphological and molecular identification of ticks was performed by microscopy and polymerase chain reaction (PCR), and the distribution of tick species, pathogen, and risk factors of infection were analyzed.ResultsIn total, 1,187 ticks were collected from the border areas of 13 localities in eight cities. Five tick species were identified: Haemaphysalis longicornis (39.68%), Ixodes persulcatus (25.36%), Haemaphysalis japonica (15.50%), Dermacentor silvarum (15.42%), and Haemaphysalis concinna (4.04%). There were more female than male ticks, and nymphs were the least frequently collected. I. persulcatus was the main species in the forest environment, while H. longicornis was the main species in grasslands and animal surface. Four pathogens were detected: Rickettsia, Bartonella, Anaplasma, and Babesia.DiscussionPathogen detection in ticks differed significantly among the environments and between Sexes. There were significant differences in the proportion of ticks infected with Rickettsia, Bartonella, Anaplasma, and Babesia among regions, species, sexes, and environments. The results of this survey of the tick species in border areas of China, Russia, and North Korea provided a scientific basis for the prevention and control of TBDs.

IntroductionHaemonchus contortus (H. contortus) infection has a significant impact on the health of pregnant ewes and adversely affects fetal development, highlighting the critical need for a non-toxic feed additive as an alternative and sustainable control strategy. Tannin is a kind of polyphenol compound, which has certain antiparasitic. The objective of this study was to evaluate the impact of dietary tannin supplementation on fecal egg count (FEC), packed cell volume (PCV), complete blood count (CBC), hormone levels, inflammatory markers, placental inflammation, and fetal growth and development in pregnant ewes infected with H. contortus.MethodsHulunbuir ewes were randomly divided into three groups: control group (CON), gastrointestinal nematode infection group (GIN), and tannin group, which was infected by H. contortus with tannin feeding therapy (TAN). After artificial insemination was completed, and the ewes were confirmed for pregnancy and infection; stools were collected for FEC, and blood samples were collected for PCV and CBC, hormonal, and inflammation levels. The mRNA levels of hypothalamic–pituitary–ovarian axis-related hormone receptors and placental tissue inflammation genes were detected by quantitative reverse transcription polymerase chain reaction (RT-qPCR). Finally, fetal weights were measured, and fetal ovarian tissue samples were taken for transcriptomic analysis.ResultsThe results showed that tannins increased the levels of gonadotropin-releasing hormone (GnRH), follicle-stimulating hormone (FSH), luteinizing hormone (LH), estrogen (E2), progesterone (P4), human chorionic gonadotropin (hCG), red blood cell (RBC) counts, packed cell volume (PCV), and mRNA levels of gonadotropic axis receptors in pregnant ewes infected with H. contortus (p &lt; 0.05). In addition, tannin reduced fecal egg count (FEC), leukocyte counts, and mRNA levels of inflammatory markers (p &lt; 0.05). In addition, fetal ovarian sequencing further showed that tannin may alleviate the delay in fetal growth and development induced by H. contortus infection (p &lt; 0.05).ConclusionIn summary, tannins have anthelmintic effects, restore reproductive hormone levels in pregnant ewes, reduce inflammation levels, and alleviate fetal growth retardation caused by H. contortus infection. Therefore, tannin is a suitable potential alternative to antibiotics as a feed additive.

Предпосылкой исследования является гипотеза о том, что для сравнения визуальных образов требуется гораздо меньше времени, чем для сравнения на слух двух мелодий. Данное исследование призвано ответить на два вопроса: можно ли при помощи визуального образа воспринять ритм сразу, без последовательного во времени изменения изображения, и насколько точно человек может воспроизвести этот ритм. Цель исследования состоит в том, чтобы определить параметр, по которому можно объективно оценивать восприятие ритма человеком, лучший вид стимула для передачи информации о ритме человеку и какое количество циклов восприятия ритмической конструкции в прослушиваемой мелодии или в синтезируемом изображении орнамента требуется человеку для того, чтобы он мог повторить этот ритм.
The premise of the study is the hypothesis that it takes much less time to compare visual images than to compare two melodies by ear. This study aims to answer two questions: is it possible to perceive the rhythm immediately with the help of a visual image, without changing the image sequentially over time; and how accurately a person can reproduce this rhythm. The purpose of the study is to determine the parameter by which a person’s perception of rhythm can be objectively assessed, the best type of stimulus for transmitting information about rhythm to a person, and how many cycles of perception of a rhythmic structure in a listened melody or in a synthesized image of an ornament is required for a person to be able to repeat this rhythm.
