Assessing the microstructure of simple rhamphothecae in chickens (Aves: Galliformes: Gallus gallus domesticus)

open access: yesJournal of Anatomy, EarlyView.
Simple rhamphotheca are externally homogeneous but internally are composed of several corneous layers with varying hardness. Areas under more mechanical stress such as the rostral portion and the tomia are significantly harder than other areas. Abstract Corneous sheaths on the jaws of beaked tetrapods, or rhamphothecae, are classified as simple or ...

A bristle‐nosed Jurassic ray‐finned fish (Actinopterygii) bears true dermal odontodes on its snout

open access: yesJournal of Anatomy, EarlyView.
Teeth show extreme diversity, including tooth‐like dermal odontodes or “skin teeth” in many extant fishes. We describe the anatomy of enlarged tubercles on the snout of Redfieldius, an extinct early Jurassic fish. We found that the tubercles in Redfieldius are dermal odontodes that evolved independently from those of living species. Abstract Comparison

Characterisation of sleep apneas and respiratory circuitry in mice lacking CDKL5

open access: yesJournal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary CDKL5 deficiency disorder is a rare genetic disease caused by mutations in the CDKL5 gene. Central apneas during wakefulness have been reported in patients with CDKL5 deficiency disorder. Studies on CDKL5‐knockout mice, a CDKL5 deficiency disorder model, reported sleep apneas, but it is still unclear whether these events are central (central ...

Potential of VIS‐IR imaging spectroscopy and SEM‐EDS and EMPA to map the mineralogical composition of NWA 7317 (CR6)

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Asteroid compositional analysis relies on comparing reflectance spectra with laboratory data from well‐characterized meteorites. To advance this comparison, we performed a comprehensive laboratory analysis on a slab of the Northwest Africa (NWA) 7317—CR6 carbonaceous chondrite.

Association Between Facial Profile Attractiveness and Full‐Face Attractiveness in Individuals With Convex Facial Profiles

open access: yesOrthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objectives Facial attractiveness significantly influences social and personal outcomes, and therefore, interventions in orthodontics and maxillofacial surgery often aim at enhancing facial appearance. This study investigated the relationship between facial profile attractiveness and overall (frontal and profile) facial attractiveness to ...

Multi‐Omics Analyses Reveal the Red and Far‐Red Light Combination Enhancing Heterologous Protein and Metabolite Production in Nicotiana benthamiana

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Transient expression of exogenous protein in Nicotiana benthamiana leaves via agroinfiltration offers a rapid and efficient platform for functional gene discovery and heterologous production of valuable eukaryotic proteins and metabolites. Though light quality is an important factor for plant photomorphogenesis, its impact on the efficiency of

Methyl Jasmonate Seed Priming Mitigates the Defence‐Growth Trade‐Off and Tailors Plant Response to Specific Pests

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Seed defence priming is emerging as a novel, cost‐efficient and environmentally safe tool for pest management. It has been proposed as a means to uncouple the defence‐growth trade‐off in plants by enhancing defence responses with minimal fitness costs, but the mechanisms underlying this role remain elusive.

Size of chloroplasts in Arabidopsis mesophyll cells affects jasmonate biosynthesis

open access: yesPlant Biology, EarlyView.
The relationship between chloroplast structure and hormone biosynthesis capacity is poorly understood. This study shows that mutants harbouring giant chloroplasts produce more jasmonic acid upon mechanical stress than wild‐type plants, suggesting that organellar architecture is a previously unrecognized factor associated with plant hormone biosynthesis
