Decoupled and diverse: A morphological examination of the two‐jaw system in Mormyridae (Osteoglossiformes)

open access: yesThe Anatomical Record, EarlyView.
Abstract The tongue‐bite apparatus (TBA) is a secondary jaw system found in Osteoglossomorpha and, convergently, Salmonidae. It is thought to have similar prey‐processing functions as the pharyngeal jaws, possibly allowing the oral jaws to evolve separately for more efficient prey capture.

Bioerosion traces in bones reveal an increase in ethological diversity in the insect exploitation of carcasses in the late Triassic

open access: yesThe Anatomical Record, EarlyView.
Abstract This study presents the first detailed description of bioerosion traces produced by insects in bones from the Santa Cruz Sequence (early Carnian, Santa Maria Supersequence, Brazil). An array of traces is reported, consisting of notches, a tube, trails of grooves attributed to the ichnotaxon Osteocallis mandibulus and ornamented depressions ...

Clock Genes Regulate Ca2+ Signaling and Mitochondrial Bioenergetics to Inhibit Sjögren Disease

open access: yesArthritis &Rheumatology, EarlyView.
Objective Although Ca2+ signaling and metabolism have been identified as key determinants for the development of Sjögren disease (SjD), the intricate connection between them and salivary gland physiology remains poorly understood. Methods Fluorescence‐based Ca2+ imaging, RNA sequencing, and mitochondrial activity were used to investigate the effects of
