The elusive scleral cartilages: Comparative anatomy and development in teleosts and avians
The Anatomical Record, EarlyView., 2023 Abstract The sclera of all vertebrate eyes is comprised of connective tissue, with some organisms developing cartilage within this tissue. A review of the cartilages that have been described in the vertebrate sclera and their anatomical relationships is discussed together with their potential homology.

Angewandte Chemie, EarlyView.Secondary metabolites (SMs) are essential across all life domains, yet those originating from the Archaea domain remain poorly understood. Here, the systematic genome mining and the pioneering heterologous expression of archaeal SMs have revealed the chemical landscape of archaeal lanthipeptides, showing both canonical and non‐canonical forms.

TAPIR enables high-throughput estimation and comparison of phylogenetic informativeness using locus-specific substitution models [PDF]
arXiv, 2012 Massively parallel DNA sequencing techniques are rapidly changing the dynamics of phylogenetic study design by exponentially increasing the discovery of phylogenetically useful loci. This increase in the number of phylogenetic markers potentially provides researchers the opportunity to select subsets of loci best-addressing particular phylogenetic ...

Angewandte Chemie, EarlyView.The structure and biosynthetic origin of the enigmatic “yellow affinity substance” (YAS) from the anaerobe thermophile Clostridium thermocellum (now: Acetivibrio thermocellus) were elucidated. YAS is a complex of unusual antibacterial arylpolyene alkaloids (celluxanthenes) that are produced by various cellulolytic anaerobes.

Antibacterial Siderophores of Pandoraea Pathogens and Their Impact on the Diseased Lung Microbiota
Angewandte Chemie, EarlyView.Genome mining of environmental and pathogenic Pandoraea species identified a conserved NRPS gene cluster and led to the discovery of novel siderophores, pandorabactins, which exert their antibacterial activity by depleting iron from competitors. Bioinformatic analysis of sputum from cystic fibrosis patients coupled with bioassays indicates that ...

Alterations in gut microbiota and metabolites contribute to postoperative sleep disturbances
Animal Models and Experimental Medicine, EarlyView.In this study, we classified postoperative patients into poor sleepers (PS) and good sleepers (GS) based on the bispectral index (BIS), and transplanted their fecal microbiota to pseudo‐germ‐free rats to analyze the sleep changes in rats and the potential mechanism.
