    UNASSIGNED: The aim of this study was to identify potential causal cytokines in thymic malignancies and benign tumors from the FinnGen database using Mendelian randomization (MR).
    UNASSIGNED: In this study, data from genome-wide association studies (GWAS) of 91 cytokines were used as exposure factors, and those of thymic malignant tumors and thymic benign tumors were the outcome variables. Two methods were used to determine the causal relationship between exposure factors and outcome variables: inverse variance weighting (IVW) and MR-Egger regression. Sensitivity analysis was performed using three methods, namely, the heterogeneity test, the pleiotropy test, and the leave-one-out test.
    UNASSIGNED: There was a causal relationship between the expression of fibroblast growth factor 5, which is a risk factor for thymic malignant tumors, and thymic malignant tumors. C-C motif chemokine 19 expression, T-cell surface glycoprotein CD5 levels, and interleukin-12 subunit beta levels were causally related to thymic malignant tumors and were protective. Adenosine deaminase levels, interleukin-10 receptor subunit beta expression, tumor necrosis factor (TNF)-related apoptosis-inducing ligand levels, and TNF-related activation-induced cytokine levels showed a causal relationship with thymic benign tumors, which are its risk factors. Caspase 8 levels, C-C motif chemokine 28 levels, interleukin-12 subunit beta levels, latency-associated peptide transforming growth factor beta 1 levels, and programmed cell death 1 ligand 1 expression showed a causal relationship with thymic benign tumors, which are protective factors. Sensitivity analysis showed no heterogeneity.
    UNASSIGNED: Cytokines showed a causal relationship with benign and malignant thymic tumors. Interleukin-12 subunit beta is a common cytokine that affects malignant and benign thymic tumors.

    脑瘫(CP)是儿童运动障碍的主要原因,痉挛型CP约占所有CP病例的70-80%。我们研究的主要目的是确定痉挛型CP的中医(TCM)症状的特征,从而建立中医症状与疾病之间的相关性,为中医治疗痉挛型CP提供更科学的理论基础,能够更深入地理解临床干预措施,最终,改善中医治疗痉挛型CP的康复效果。
    我们对陕西中医药大学附属西安脑病医院4-14岁痉挛型CP患儿的中医症状进行了数据挖掘研究,从2021年10月到2023年3月。提取所有符合条件且完全痉挛的CP患者的病历,处理以进行数据清理,转换,并随后进行分析以辨别独特的中医症状。采用K-means聚类分析和关联规则分析进行数据挖掘。
    确定的痉挛CP的核心症状包括“运动障碍”,“言语受损”,“延迟开发”,“肢体僵硬度”,“四肢的刚性”,“智力障碍”,“对惊吓反应的胆怯和敏感性”,“肌肉浪费”,和“苍白或沉闷的肤色”。在症状的顶级关联中,出现“运动功能障碍”与“言语受损”交织在一起的模式,“运动功能障碍”与“发育迟缓”并存,和“言语受损”伴随着“延迟发展”。
    这项研究确定了痉挛型CP的核心症状,并初步表明痉挛型CP的临床表现与中医“肝旺脾虚”基本一致。这一发现促进了中医模式识别与医学疾病之间相关性的初步建立。预计这种相关性将为更多患有痉挛性CP的儿童带来切实的好处。
    UNASSIGNED: Cerebral palsy (CP) ranks as a major cause of motor disabilities in children, with spastic CP making up roughly 70-80% of all CP cases. The primary objective of our study is to identify characteristics of Traditional Chinese Medicine(TCM) symptom of spastic CP, thereby establishing correlations between the TCM symptom and the disease, providing a more scientific theoretical foundation for TCM treatments on spastic CP, enabling a deeper comprehension of clinical interventions, ultimately, improving rehabilitation outcomes in TCM treatment for spastic CP.
    UNASSIGNED: We conducted a data mining study on TCM symptom of spastic CP children aged 4-14 years old treated at Xi\'an Encephalopathy Hospital Affiliated to Shaanxi University of Chinese Medicine, from October 2021 to March 2023. The medical records of all eligible and complete spastic CP patients were extracted, processed for data cleansing, transformed, and subsequently analyzed to discern distinctive TCM symptom. K-Means Clustering Analysis and Association Rule Analysis were used for data mining.
    UNASSIGNED: Core symptoms identified for spastic CP encompassed \"Motor Dysfunction\", \"Impaired Speech\", \"Delayed Development\", \"Limb Stiffness\", \"Rigidity in the limbs\", \"Intellectual Impairment\", \"Timidity and susceptibility to startle responses\", \"Muscle Wasting\", and \"Pale or Dull Complexion\". Among the top-ranking associations of symptom, patterns emerge wherein \"Motor dysfunction\" intertwine with \"Impaired speech\", \"Motor dysfunction\" coexist with \"Delayed development\", and \"Impaired speech\" are accompanied by \"Delayed development\".
    UNASSIGNED: This study identified the core symptom of spastic CP and tentatively suggests that the clinical manifestations of spastic CP are essentially consistent with the TCM pattern \"liver exuberance and spleen weakness\". This finding has facilitated the preliminary establishment of correlations between TCM pattern differentiation and the disease in medicine. It is anticipated that this correlation will bring tangible benefits to a larger number of children with spastic CP.

    标准化和翻译来自不同数据库的物种名称是生物多样性研究中成功整合数据源的关键。有许多分类名称解析应用程序实现了越来越强大的名称清理和匹配方法,允许用户同时解析相对于多个主干的物种。然而,仍然没有原则性的方法来组合这些潜在的分类骨干的信息,使合并和合并具有不一致和冲突的分类学信息的物种列表的努力复杂化。这里,我们呈现的是巨大的,用于R编程环境的开源软件包,该软件包集成了四个公开可用的主干之间的分类关系,以改善树种的名称分辨率。通过映射跨骨干的关系,这个软件包可以用来解决具有冲突和不一致的分类起源的数据集,同时确保所产生的物种被接受并与单个参考主链一致。用户可以将从简单匹配到单个主干的不同功能链接在一起,使用数据库中所有主干的同义词接受的关系进行基于图的迭代匹配。此外,该软件包允许用户将一个树种列表转换为另一个树种列表,简化新数据到现有数据集或模型的同化。该软件包根据用例提供了灵活的工作流程,,并且可以用作独立的名称解析包,也可以与现有包一起用作名称解析管道中的最后一步。Treemendous包装是快速和易于使用,允许用户通过根据定期更新的数据库标准化其物种名称来快速合并不同的数据源。通过组合多个主干的分类信息,该软件包提高了匹配率并最大程度地减少了数据丢失,允许更有效地翻译树种数据集,以帮助研究森林生物多样性和树木生态学。
    Standardizing and translating species names from different databases is key to the successful integration of data sources in biodiversity research. There are numerous taxonomic name-resolution applications that implement increasingly powerful name-cleaning and matching approaches, allowing the user to resolve species relative to multiple backbones simultaneously. Yet there remains no principled approach for combining information across these underlying taxonomic backbones, complicating efforts to combine and merge species lists with inconsistent and conflicting taxonomic information. Here, we present Treemendous, an open-source software package for the R programming environment that integrates taxonomic relationships across four publicly available backbones to improve the name resolution of tree species. By mapping relationships across the backbones, this package can be used to resolve datasets with conflicting and inconsistent taxonomic origins, while ensuring the resulting species are accepted and consistent with a single reference backbone. The user can chain together different functionalities ranging from simple matching to a single backbone, to graph-based iterative matching using synonym-accepted relations across all backbones in the database. In addition, the package allows users to \'translate\' one tree species list into another, streamlining the assimilation of new data into preexisting datasets or models. The package provides a flexible workflow depending on the use case, and can either be used as a stand-alone name-resolution package or in conjunction with existing packages as a final step in the name-resolution pipeline. The Treemendous package is fast and easy to use, allowing users to quickly merge different data sources by standardizing their species names according to the regularly updated database. By combining taxonomic information across multiple backbones, the package increases matching rates and minimizes data loss, allowing for more efficient translation of tree species datasets to aid research into forest biodiversity and tree ecology.

    In response to growing concerns about the efficacy of antibiotic treatment, there has been a significant increase in research on bacteria that are resistant to antibiotics over the past two centuries. Such investigations might bring a spotlight on the field\'s evolution and future prospects. The study was aimed at conducting a measurable bibliometric review of the scientific literature on bacterial persistence and dormancy in the 21st Century. A scientific literature published during 21st Century was analyzed to gain insights into and identify research trends and outputs in persistent bacteria. Bibliometrix (R language package) and the VOS viewer were used to conduct a bibliometric investigation to determine the globally indexed persistent bacteria research output. WoS Core Collection databases were searched for persistent bacteria selected as the subject. A total of 1,160 published documents from 495 sources from the preceding two decades were reviewed. Maximum publications of 112 were observed in 2021 with 860 citations; however, 82 publications appeared in 2015 and were able to get the highest number of citations (4,214), only 43 (3.7%) were single-authored, whereas 1,117 (96.3%) publications are the result of collaborative works. Out of the top 10 countries ranked for publications, the USA took the top spot for the most highly productive country with 435 articles. Dormancy\' appeared 2,351 times, followed by \'Escherichia coli\" (1,744, and \'Growth\' 1,184 times) in research publications on bacterial persistence research. The findings from this study will aid in the creation of strategies and guidelines for regulating and avoiding bacterial persistence status.

    生态和进化研究通常需要高质量的生物多样性数据。这些信息可以通过许多在线数据库随时获得,这些数据库汇编了草本植物的生物多样性数据,博物馆,和人类的观察。然而,准备此信息进行分析的过程是复杂且耗时的。在这项研究中,我们用R语言开发了一个处理空间数据的协议(下载,合并,干净,并且正确)并提取气候数据,以人参科的一些属(天花科)为例。该协议提供了一种自动方式,可以独立地从多个在线数据库处理众多分类单元的空间和气候数据。该脚本使用GBIF,BIEN,和WorldClim作为在线数据源,但可以很容易地适应包括其他在线数据库。该脚本还使用属作为采样单位,但提供了一种使用物种作为目标的方法。清洁过程包括一个过滤器,以去除分类单元自然范围之外的事件,花园,和其他人类环境,以及错误的位置和对错位事件的空间校正(即,在与沿海边界相距一定距离的缓冲区内发生事件)。此外,协议的每个步骤都可以独立运行。因此,协议可以从数据清理开始,如果数据库已经编译,或者提取气候数据,如果数据库已经被解析。R脚本的每一行都有注释,因此它也可以由对R知之甚少的用户运行。
    Ecological and evolutionary studies often require high quality biodiversity data. This information is readily available through the many online databases that have compiled biodiversity data from herbaria, museums, and human observations. However, the process of preparing this information for analysis is complex and time consuming. In this study, we have developed a protocol in R language to process spatial data (download, merge, clean, and correct) and extract climatic data, using some genera of the ginseng family (Araliaceae) as an example. The protocol provides an automated way to process spatial and climatic data for numerous taxa independently and from multiple online databases. The script uses GBIF, BIEN, and WorldClim as the online data sources, but can be easily adapted to include other online databases. The script also uses genera as the sampling unit but provides a way to use species as the target. The cleaning process includes a filter to remove occurrences outside the natural range of the taxa, gardens, and other human environments, as well as erroneous locations and a spatial correction for misplaced occurrences (i.e., occurrences within a distance buffer from the coastal boundary). Additionally, each step of the protocol can be run independently. Thus, the protocol can begin with data cleaning, if the database has already been compiled, or with climatic data extraction, if the database has already been parsed. Each line of the R script is commented so that it can also be run by users with little knowledge of R.

    目的:男性和女性在某些特征中的性二态性程度因样本而异。尽管在生物人类学研究中经常报道性别的特征差异,很少有研究测试统计意义或提供原始数据。TestDimorph是第一个R包,致力于通过利用汇总统计数据来测试和比较不同样本之间的性二态性程度。
    方法:我们提供了两种分析样本间性别二态性程度差异的方法:两个或多个样本的单变量和多变量。该方法遵循主要来自AJBA的出版物。使用单向ANOVA比较样品之间的性别内大小变异性,随后使用对照进行多次成对比较。此外,我们使用相异指数计算两个正态分布的密度函数之间的重叠区域,以及使用95%置信区间的具有推理支持的Hedges\'g。最后,我们对样本之间的性二态模式差异进行了多变量分析。
    结果:我们展示了将TestDimorph函数应用于软件包提供的数据的各种结果。
    结论:该软件包具有许多功能,包括处理汇总统计数据的功能,模拟汇总统计数据,从原始数据中提取汇总统计数据,以便整个分析可以通过软件包进行。
    The degree of sexual dimorphism in certain traits between males and females differ from one sample to another. Although trait differences by sex are often reported in bioanthropological research, few studies test for statistical significance or make raw data available. TestDimorph is the first R package dedicated to testing and comparing the degree of sexual dimorphism among different samples by leveraging summary statistics.
    We provide two approaches of analysis of inter-sample differences in degree of sexual dimorphism: univariate and multivariate for two or more samples. The methods follow upon publications primarily from the AJBA. Within-sex size variability between samples is compared using one-way ANOVA followed by control for multiple pairwise comparisons. In addition, we compute the overlapping area between the density functions of two normal distributions from the mixture intersection index or the non-overlapping area using the dissimilarity index as well as Hedges\' g with inferential support using the 95% confidence interval. Finally, we use a multivariate analysis of differences in patterning of sexual dimorphism between samples.
    We demonstrate various results from applying TestDimorph functions to data supplied with the package.
    The package has many features including functionality for working with summary statistics, simulating data from summary statistics, and the extraction of summary statistics from raw data, so that the entire analysis can be performed through the package.
