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 ...

Surface roughness, stainability, and translucency of an additively manufactured interim resin reinforced with a commercially available ceramic composite concentrate after coffee thermal cycling

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose To compare the surface roughness (Ra), stainability, and translucency of a ceramic composite concentrate‐reinforced interim resin with its corresponding non‐reinforced formulation and with a ceramic‐filled resin indicated for definitive use after coffee thermal cycling.

Substrate Stiffness and Viscoelasticity Influence Fibroblast Senescence

open access: yesJournal of Biomedical Materials Research Part A, Volume 114, Issue 7, July 2026.
ABSTRACT Senescent cell accumulation has been implicated in aging and fibrotic disease, which are both characterized by increased tissue stiffness. However, the direct connection between tissue mechanics and senescence induction remains disputed in the literature.

Fatigue Strength Analysis of a Cladded Steel Subjected to Tensile Predeformation

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 7, Page 2767-2779, July 2026.
ABSTRACT Cladded steels are a subset of layered metal composites in which a thin functional layer is bonded to a dissimilar substrate, thereby integrating the benefits of both constituent materials. However, the resulting heterogeneous properties of such layered metal composites collectively complicate deformation and fatigue behavior, making reliable ...
