Article Abstract
Type specimens of four species of (Myxomycetes, Amoebozoa)-, and have been studied using an integrative approach including application of traditional taxonomy methods, i.e., morphological study under stereoscopic and compound microscopes, detailed analysis of micromorphological characters using scanning electron microscopy, and molecular analysis by way of Sanger sequencing of molecular markers (nuc 18S rDNA and elongation factor 1-alpha gene, ). Results of the study revealed that is conspecific with is a malformed specimen of , whereas and represent two well-defined morphologically and genetically separate species. Phylogeny of Physarales shows the polyphyletic character of the genus . The type species of clusters together with , whereas other representatives of this genus form a monophyletic, well-supported clade. The species from this clade are proposed to belong to the genus described by A. Corda in 1842 that is resurrected and emended here. Nine species of are transferred to . A new key to Didymiaceae including is provided.

Dissecting Causal Relationships Between Antihypertensive Drug, Gut Microbiota, and Type 2 Diabetes Mellitus and Its Complications: A Mendelian Randomization Study.

Limited research has investigated the impact of antihypertensive medications on type 2 diabetes mellitus (T2DM) and whether gut microbiome (GM) mediates this association. Thus, we conducted a two-sample Mendelian randomization (MR) analysis to estimate the potential impact of various antihypertensive drug target genes on T2DM and its complications. Genetic instruments for the expression of antihypertensive drug target genes were identified with expression quantitative trait loci (eQTL) in blood, which should be associated with systolic blood pressure (SBP).

A facultative anaerobic, Gram-stain-negative, non-motile, rod-shaped bacterial strain AGMB14963 was isolated from the feces of a dairy cow. A 16S rRNA gene sequence-based phylogenetic analysis revealed that strain AGMB14963 belongs to the genus Gallibacterium, with Gallibacterium salpingitidis F150 being the closest species (95.8% 16S rRNA gene sequence similarity).

Background: Common variable immunodeficiency (CVID) is characterized by hypogammaglobulinemia and recurrent infections. Significant morbidity and mortality are caused by immune dysregulation complications (CVIDid), which affect around one-third of CVID patients and have a poorly understood etiology. Here, we investigate the hypothesis that gut microbial dysbiosis contributes to the inflammation underlying CVIDid.

As a universal language across the bacterial kingdom, the quorum sensing signal autoinducer-2 (AI-2) can coordinate many bacterial group behaviors. However, unknown AI-2 receptors in bacteria may be more than what has been discovered so far, and there are still many unknown functions for this signal waiting to be explored. Here, we have identified a membrane-bound histidine kinase of the pathogenic bacterium , AsrK, as a receptor that specifically detects AI-2 under low boron conditions.

E-mail: ORCID: 0000-0003-1086-1181.
The present paper comprises a systematic survey of trematodes and acanthocephalans based on helminthological examinations of 64 specimens of 14 species of freshwater fishes, belonging to six families of four fish orders, mostly from localities in Hubei Province, central China, collected in the autumn of 2002. A total of 15 trematode species (in 12 families) and 5 acanthocephalan species (in four families) was recorded. Almost all parasites are briefly described and illustrated and problems concerning their morphology, taxonomy, hosts and geographical distribution are discussed.
