    Therocephalia是非哺乳动物疗法的重要分支,在其进化史上进化出各种各样的形态类型和体型。海洋动物的颅后解剖在很大程度上被忽视了,但对于理解它们的古生物学和系统发育关系仍然很重要。这里,通过检查南非化石收藏中的多个标本,我们提供了大型akidnognathideutherocephalianMoschorhinuskitchingi的首次颅后描述。我们还将颅后解剖结构与先前描述的头颅后材料进行了比较,并提供了最新的文献综述,以确保为将来的描述性工作提供可靠的比较基础。Moschorhinus具有远洋动物的所有颅后特征,这些特征将它们与早期发散的远洋动物区分开来,但在肩胛骨方面与其他远洋类群不同,锁骨间,胸骨,Manus,和股骨。这项贡献的新解剖学数据表明,Moschorhinus拥有一个矮胖的bauplan和一个特别健壮的肩胛骨,肱骨,和股骨。这些属性,再加上短而坚固的头骨,带有扩大的圆锥形犬齿,这意味着Moschorhinus装备精良,可以应付和制服猎物。此外,这些属性的组合不同于那些类似大小的中世纪戈戈诺帕斯人,在晚二叠纪生态系统中占据了类似的生态位。此外,Moschorhinus是已知在二叠纪-三叠纪大灭绝中幸存下来的唯一大型食肉动物。因此,微妙但重要的颅后差异可能暗示了在二叠纪-三叠纪大规模灭绝间隔期间捕食者公会中的一种生态位划分。
    Therocephalia are an important clade of non-mammalian therapsids that evolved a diverse array of morphotypes and body sizes throughout their evolutionary history. The postcranial anatomy of therocephalians has largely been overlooked, but remains important towards understanding aspects of their palaeobiology and phylogenetic relationships. Here, we provide the first postcranial description of the large akidnognathid eutherocephalian Moschorhinus kitchingi by examining multiple specimens from fossil collections in South Africa. We also compare the postcranial anatomy with previously described therocephalian postcranial material and provide an updated literature review to ensure a reliable foundation of comparison for future descriptive work. Moschorhinus shares all the postcranial features of eutherocephalians that differentiate them from early-diverging therocephalians, but is differentiated from other eutherocephalian taxa by aspects concerning the scapula, interclavicle, sternum, manus, and femur. The novel anatomical data from this contribution shows that Moschorhinus possessed a stocky bauplan with a particularly robust scapula, humerus, and femur. These attributes, coupled with the short and robust skull bearing enlarged conical canines imply that Moschorhinus was well equipped to grapple with and subdue prey items. Additionally, the combination of these attributes differ from those of similarly sized coeval gorgonopsians, which would have occupied a similar niche in late Permian ecosystems. Moreover, Moschorhinus was the only large carnivore known to have survived the Permo-Triassic mass extinction. Thus, the subtle but important postcranial differences may suggest a type of niche partitioning in the predator guild during the Permo-Triassic mass extinction interval.

    木霉属物种通过寄生和共生机制与植物建立共生关系。虽然一些木霉属物种作为植物病原真菌,其他人利用各种策略来保护和促进植物生长。
    木霉属新物种的系统发育位置是通过依赖于核糖体DNA的内部转录间隔区(ITS)区域的多基因分析确定的,翻译延伸因子1-α(tef1-α)基因,和RNA聚合酶II(rpb2)基因。此外,进行了致病性实验,并根据感染部位的横截面面积评估每个分离株的侵袭性。
    在这项研究中,13种木霉属,包括9个已知物种和4个新物种,即,T.delicatum,T.罗布图姆,T.perfasculatum,从云南天麻病块茎中分离出地下T。中国。在已知的物种中,T.hamatum的频率最高。T.delicatum属于Koningii进化枝。robustum和perfasciculatum被分配到Virens进化枝。T.Subulatum成为Spirale进化枝的新成员。对新物种T.robustum进行了致病性实验,T.delicatum,和T.perfasculatum,以及已知的T.hamatum物种,T.atroviride,还有T.harzianum.不同木霉属物种对白斑的感染能力不同,表明木霉是G.elata黑腐病的病原真菌。
    这项研究提供了新物种的形态特征,并讨论了与系统发育邻近物种的形态差异,为旨在预防和管理影响G.elata的疾病的研究奠定基础。
    UNASSIGNED: Trichoderma species establish symbiotic relationships with plants through both parasitic and mutualistic mechanisms. While some Trichoderma species act as plant pathogenic fungi, others utilize various strategies to protect and enhance plant growth.
    UNASSIGNED: Phylogenetic positions of new species of Trichoderma were determined through multi-gene analysis relying on the internal transcribed spacer (ITS) regions of the ribosomal DNA, the translation elongation factor 1-α (tef1-α) gene, and the RNA polymerase II (rpb2) gene. Additionally, pathogenicity experiments were conducted, and the aggressiveness of each isolate was evaluated based on the area of the cross-section of the infected site.
    UNASSIGNED: In this study, 13 Trichoderma species, including 9 known species and 4 new species, namely, T. delicatum, T. robustum, T. perfasciculatum, and T. subulatum were isolated from the diseased tubers of Gastrodia elata in Yunnan, China. Among the known species, T. hamatum had the highest frequency. T. delicatum belonged to the Koningii clade. T. robustum and T. perfasciculatum were assigned to the Virens clade. T. subulatum emerged as a new member of the Spirale clade. Pathogenicity experiments were conducted on the new species T. robustum, T. delicatum, and T. perfasciculatum, as well as the known species T. hamatum, T. atroviride, and T. harzianum. The infective abilities of different Trichoderma species on G. elata varied, indicating that Trichoderma was a pathogenic fungus causing black rot disease in G. elata.
    UNASSIGNED: This study provided the morphological characteristics of new species and discussed the morphological differences with phylogenetically proximate species, laying the foundation for research aimed at preventing and managing diseases that affect G. elata.

    先前的生态研究表明,斯珀蒙群岛的海绵多样性更高,苏拉威西岛西南部,印度尼西亚,与世界Porifera数据库相比。这项研究旨在提供Spermonde群岛海绵的最新清单,特别关注沿海地区。通过几次观察进行了系统抽样,用巡回技术,例如,浮潜和SCUBA潜水。使用水下数码相机拍摄了现场海绵照片。一些标本被收集并储存在自然生物多样性中心,莱顿使用光学和扫描电子显微镜分析样品的碎片。从Spermonde群岛的沿海地区共编目了27个海绵(Calcarea和Demospongiae)。其中一些是苏拉威西海/望加锡海峡海洋生态区的新记录,包括四个潜在的新分类群。提供了所有检查样品的初步形态学描述。这项研究强调了在浅水区蓬勃发展的海绵组合,其特征是缺乏活珊瑚和大型藻类的主要环境,岩石,还有瓦砾.
    Previous ecological studies show higher sponge diversity in the Spermonde Archipelago, SW Sulawesi, Indonesia, compared to the World Porifera Database. This study aims to provide an updated checklist of sponges of the Spermonde Archipelago, focusing particularly on the littoral area. Systematic sampling was executed through several observations, with roving techniques, e.g., snorkeling and SCUBA diving. In situ photographs of living sponges were taken using an underwater digital camera. Some specimens were collected and stored at the Naturalis Biodiversity Center, Leiden. Fragments of samples were analyzed using light and scanning electron microscopy. A total of 27 sponges (Calcarea and Demospongiae) were catalogued from the littoral area of the Spermonde Archipelago. Some of these are new records for the Sulawesi Sea/Makassar Strait marine ecoregion, including four potentially novel taxa. Preliminary morphological descriptions of all examined samples are presented. This study highlights the sponge assemblage flourishing in a shallow area characterized by a paucity of live corals and a predominant environment by macroalgae, rocks, and rubble.

    下一代测序技术现在可用于对自然历史收藏品中的历史标本进行测序,一种被称为博物馆组学的方法。博物馆组学允许从博物馆保存的旧标本中获得分子数据,尽管这些标本通常是命名类型的独特样本,对于解决科学问题至关重要,但生物分子的资源在很大程度上未得到充分利用。尽管最近的技术进步,板球有丝分裂基因组在数据库中仍然很少,每年从新鲜收集的材料中产生的新材料很少。
    在这项研究中,我们使用基因组撇脂方法对三个新的完整的有丝分裂基因组进行测序和组装,它们代表了板球亚科的两个部落:两个是从旧的,Xenogrylluslamottei(68岁)和X.maniema(80岁)的历史类型材料,第三个来自新收集的Nisitrusvittatus标本。我们比较了它们的基因组组织和碱基组成,并重建了Gryllidae家族的分子系统发育。
    我们的研究不仅证实了下一代测序使用的基因组撇脂方法使我们能够有效地从干钉的历史标本中获得整个有丝分裂基因组,但我们也证实了它是多么有希望的大规模比较研究的有丝分裂基因组利用资源从自然历史收集。在系统发育环境中使用的新有丝分裂基因组证明有丝分裂基因组数据包含有价值的信息,并且还强烈支持多个时间尺度的系统发育关系。
    UNASSIGNED: Next-generation sequencing technology can now be used to sequence historical specimens from natural history collections, an approach referred to as museomics. The museomics allows obtaining molecular data from old museum-preserved specimens, a resource of biomolecules largely underexploited despite the fact that these specimens are often unique samples of nomenclatural types that can be crucial for resolving scientific questions. Despite recent technical progress, cricket mitogenomes are still scarce in the databases, with only a handful of new ones generated each year from freshly collected material.
    UNASSIGNED: In this study, we used the genome skimming method to sequence and assemble three new complete mitogenomes representing two tribes of the cricket subfamily Eneopterinae: two were obtained from old, historical type material of Xenogryllus lamottei (68 years old) and X. maniema (80 years old), the third one from a freshly collected specimen of Nisitrus vittatus. We compared their genome organization and base composition, and reconstructed the molecular phylogeny of the family Gryllidae.
    UNASSIGNED: Our study not only confirmed that the genome skimming method used by next generation sequencing allows us to efficiently obtain the whole mitogenome from dry-pinned historical specimens, but we also confirmed how promising it is for large-scale comparative studies of mitogenomes using resources from natural history collections. Used in a phylogenetic context the new mitogenomes attest that the mitogenomic data contain valuable information and also strongly support phylogenetic relationships at multiple time scales.

    非酒精性脂肪性肝病(NAFLD),或代谢功能障碍相关的脂肪变性肝病(MASLD),是一种与超重有关的肝脏疾病,肥胖,糖尿病,和代谢综合征。非酒精性脂肪性肝炎(NASH),或代谢功能障碍相关脂肪性肝炎(MASH),是NAFLD/MASLD的一种形式,随着时间的推移而发展。虽然脂肪变性是一个突出的组织学特征,并且在显微镜下可以大致识别,NASH/MASH患者的肝活检可能表现出其他几种异常,例如门静脉和小叶区域的单核炎症,以膨胀和程序性细胞死亡(凋亡)为特征的肝细胞损伤,错误折叠的肝细胞蛋白内含物(Mallory-Denk体,MDB),巨型线粒体作为透明内含物,和纤维化。球囊性肝细胞损伤仍然是NASH/MASH的定义特征。纤维化模式的特征是窦周纤维化(“鸡丝”)和中央静脉周围纤维化的初始表达。儿童可能患有以脂肪变性为特征的进行性NAFLD/MASLD的替代形式,炎症,和纤维化,主要在肝腺泡的Rappaport1区。为了识别,合成,并分析在综合叙述回顾中使用评分评估NAFLD/MASLD的含义所产生的科学知识。文章的搜索是在2000年1月1日至2023年12月31日期间在PubMed/MEDLINE上进行的,Scopus,WebofScience,和Cochrane数据库。这个搜索得到了灰色搜索的补充,包括互联网浏览器(例如,谷歌)和教科书。以下研究问题指导了该研究:“使用评分评估NAFLD/MASLD的基本数据是什么?”选择过程的所有阶段均由作者进行。在发现的1783篇文章中,75个样本被包括在分析中,这是通过参考文献和灰色文献中的另外25篇文章实施的。分析的研究表明对肝活检进行评分的有益效果。尽管酒精性脂肪性肝炎(ASH)和NASH/MASH之间存在相似性,在肝脏酒精性疾病中看到的某些肝细胞损伤模式在NASH/MASH中不会发生,包括以脂肪性肝炎为特征的胆汁淤积,酒精性泡沫变性,和硬化性以透明坏死为主.一般来说,富含中性粒细胞的细胞浸润,突出的透明夹杂物和MDB,胆汁淤积,与NASH/MASH相比,明显的细胞周围纤维化应更有利于酒精引起的肝细胞损伤的诊断。多种分级和分期方法可在调查和临床试验中实施,每个都有优点和缺点。主要使用的系统是Brunt,NASHCRN(NASH临床研究网络),和SAF(脂肪变性,活动,和纤维化)系统。临床研究已经利用几种方法将实验室和人口统计学观察与组织学发现与快速商业化药物临床试验的最佳平台联系起来。机器学习程序(人工智能)对于开发新平台以评估当前和未来药物配方的益处至关重要。
    Nonalcoholic fatty liver disease (NAFLD), or metabolic dysfunction-associated steatotic liver disease (MASLD), is a liver condition that is linked to overweight, obesity, diabetes mellitus, and metabolic syndrome. Nonalcoholic steatohepatitis (NASH), or metabolic dysfunction-associated steatohepatitis (MASH), is a form of NAFLD/MASLD that progresses over time. While steatosis is a prominent histological characteristic and recognizable grossly and microscopically, liver biopsies of individuals with NASH/MASH may exhibit several other abnormalities, such as mononuclear inflammation in the portal and lobular regions, hepatocellular damage characterized by ballooning and programmed cell death (apoptosis), misfolded hepatocytic protein inclusions (Mallory-Denk bodies, MDBs), megamitochondria as hyaline inclusions, and fibrosis. Ballooning hepatocellular damage remains the defining feature of NASH/MASH. The fibrosis pattern is characterized by the initial expression of perisinusoidal fibrosis (\"chicken wire\") and fibrosis surrounding the central veins. Children may have an alternative form of progressive NAFLD/MASLD characterized by steatosis, inflammation, and fibrosis, mainly in Rappaport zone 1 of the liver acinus. To identify, synthesize, and analyze the scientific knowledge produced regarding the implications of using a score for evaluating NAFLD/MASLD in a comprehensive narrative review. The search for articles was conducted between 1 January 2000 and 31 December 2023, on the PubMed/MEDLINE, Scopus, Web of Science, and Cochrane databases. This search was complemented by a gray search, including internet browsers (e.g., Google) and textbooks. The following research question guided the study: \"What are the basic data on using a score for evaluating NAFLD/MASLD?\" All stages of the selection process were carried out by the single author. Of the 1783 articles found, 75 were included in the sample for analysis, which was implemented with an additional 25 articles from references and gray literature. The studies analyzed indicated the beneficial effects of scoring liver biopsies. Although similarity between alcoholic steatohepatitis (ASH) and NASH/MASH occurs, some patterns of hepatocellular damage seen in alcoholic disease of the liver do not happen in NASH/MASH, including cholestatic featuring steatohepatitis, alcoholic foamy degeneration, and sclerosing predominant hyaline necrosis. Generally, neutrophilic-rich cellular infiltrates, prominent hyaline inclusions and MDBs, cholestasis, and obvious pericellular sinusoidal fibrosis should favor the diagnosis of alcohol-induced hepatocellular injury over NASH/MASH. Multiple grading and staging methods are available for implementation in investigations and clinical trials, each possessing merits and drawbacks. The systems primarily used are the Brunt, the NASH CRN (NASH Clinical Research Network), and the SAF (steatosis, activity, and fibrosis) systems. Clinical investigations have utilized several approaches to link laboratory and demographic observations with histology findings with optimal platforms for clinical trials of rapidly commercialized drugs. It is promising that machine learning procedures (artificial intelligence) may be critical for developing new platforms to evaluate the benefits of current and future drug formulations.

    RNA病毒的特征在于广泛的宿主范围和高水平的遗传多样性。尽管最近在宏基因组测序后已知的病毒层有所扩大,我们对RNA病毒物种的认识排名遗传多样性,以及他们被错误分配和错误分类的频率,是有限的。我们对代表1897个已建立的RNA病毒物种的7801RNA定向RNA聚合酶(RdRp)序列进行了聚类分析。由此,我们发现,在GenBank数据库和国际病毒分类学委员会(ICTV)之间,某些病毒物种之间存在显著的遗传差异,并且RNA病毒分配不一致.特别是,27.57%的病毒物种包括多个病毒操作分类单位(vOTU),包括流感甲型流感病毒,拉萨哺乳动物病毒,苹果茎点蚀病毒,和轮状病毒A,每个都有超过100个votu。此外,单个指定物种内vOTUs之间的平均氨基酸同一性分布显示出相对较低的阈值:<90%,有时<50%.然而,当只分析病毒物种的样本序列时,将1889年ICTV指定的RNA病毒物种(99.58%)聚集到单个vOTU中。来自不同病毒物种的RdRp序列的聚类还表明,17个vOTU包含两个不同的病毒物种。通过系统发育分析证实了这些潜在的错误分配。对70%至97.5%的平均核苷酸同一性(ANI)值的进一步分析显示,在82.5%的ANI下,1559(82.18%)的1897病毒物种可以正确地聚集到一个单一的vOTU中。然而,在ANI值>82.5%时,越来越多的物种聚集到两个或更多的vOTUs中。总之,我们仅基于对RdRp序列的分析,就确定了RNA病毒物种的一些不一致和错误分配,这对自动化RNA病毒分类系统的开发具有重要意义。
    RNA viruses are characterized by a broad host range and high levels of genetic diversity. Despite a recent expansion in the known virosphere following metagenomic sequencing, our knowledge of the species rank genetic diversity of RNA viruses, and how often they are misassigned and misclassified, is limited. We performed a clustering analysis of 7801 RNA-directed RNA polymerase (RdRp) sequences representing 1897 established RNA virus species. From this, we identified substantial genetic divergence within some virus species and inconsistency in RNA virus assignment between the GenBank database and The International Committee on Taxonomy of Viruses (ICTV). In particular, 27.57% virus species comprised multiple virus operational taxonomic units (vOTUs), including Alphainfluenzavirus influenzae, Mammarenavirus lassaense, Apple stem pitting virus, and Rotavirus A, with each having over 100 vOTUs. In addition, the distribution of average amino acid identity between vOTUs within single assigned species showed a relatively low threshold: <90% and sometimes <50%. However, when only exemplar sequences from virus species were analyzed, 1889 of the ICTV-designated RNA virus species (99.58%) were clustered into a single vOTU. Clustering of the RdRp sequences from different virus species also revealed that 17 vOTUs contained two distinct virus species. These potential misassignments were confirmed by phylogenetic analysis. A further analysis of average nucleotide identity (ANI) values ranging from 70% to 97.5% revealed that at an ANI of 82.5%, 1559 (82.18%) of the 1897 virus species could be correctly clustered into one single vOTU. However, at ANI values >82.5%, an increasing number of species were clustered into two or more vOTUs. In sum, we have identified some inconsistency and misassignment of the RNA virus species based on the analysis of RdRp sequences alone, which has important implications for the development of an automated RNA virus classification system.
