Cortical bone distribution in the human mandibular symphysis: Ontogenic and morphometric approaches in archeological context

open access: yesThe Anatomical Record, EarlyView.
Abstract The human mandibular symphysis concentrates multiaxial loads during function and remodels throughout growth, but the precise mechanisms underlying cortical bone shape during growth remain relatively unexplored. Approaches based solely on thickness or external cortical contours provide only partial insights and do not capture the functional ...

Description of large, well‐preserved Enchodus specimens from the Bearpaw Formation of Alberta, Canada

open access: yesThe Anatomical Record, EarlyView.
Abstract Fishes of the genus Enchodus were abundant and cosmopolitan in the Late Cretaceous, but are primarily known from isolated remains in Canada. Four well‐preserved fish skulls were recovered in recent years from ammolite mines sampling the Bearpaw Formation of Southern Alberta, and are here referred to Enchodus petrosus Cope, 1874.

Postnatal craniomandibular growth in Harbor seals (Phoca vitulina vitulina)

open access: yesThe Anatomical Record, EarlyView.
Postnatal ontogeny in Harbor seals (Phoca vitulina vitulina). Cranium and mandible grow rapidly until 5 years of age, followed by a deceleration and finally a stagnation. Abstract As secondarily aquatic carnivores, seals display several phenotypic differences compared to their terrestrial relatives.

Targeting neutrophil extracellular traps in metabolic and immune niche: Nanomaterials for diabetes tissue regeneration

open access: yesBMEMat, EarlyView.
The effects of NETs on regeneration of various diabetic tissues, and strategies targeting NETs for diabetes tissue regeneration. In the diabetic environment, NETs undergo complex metabolic and immune reprogramming, leading to dynamic changes in antibacterial and proinflammatory functions, and affecting regeneration of multiple systemic tissues.

Optimized micro‐sized cell sphere‐matrix niche co‐aggregates promote efficient oral and craniomaxillofacial bone regeneration

open access: yesBMEMat, EarlyView.
The construct of cell‐niche co‐aggregates (GelMA‐SHED sphere‐DDMPs) promotes cranial and periodontal bone regeneration and ensures angiogenic‐osteogenic coupling by downregulating miR‐34c‐5p to enhance the expression of NOTCH1 and its intracellular domain (NICD).
