Nacre‐inspired layered composite with excellent mechanical support and osteogenic potential for cervical interbody cage

BMEMat, EarlyView.
The cervical interbody cage needs to take both biomechanical and biological requirements into account. Here, a new‐style degradable, multicomponent, and bioinspired nacre‐like cervical interbody cage composite, which exhibits promising mechanical‐support‐related behavior and osteogenesis‐related potential, is designed and prepared.

Evidence for adaptive explanations of semelparity in animals

Biological Reviews, EarlyView.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

Anatomy of the Soft Palate and Its Role in Upper Airway Function: A Narrative Review

Clinical Anatomy, EarlyView.
ABSTRACT The soft palate is a complex anatomical structure, located at the posterior aspect of the oral and nasal cavities, able to dynamically create valve closure of the nasal and the oral cavities. Its precise movement is critical for speech, swallowing, and respiration. Despite its functional importance, detailed characterization of its constituent

Tooth autotransplantation combined with bone augmentation for reconstruction of the esthetic zone: A case report

Clinical Advances in Periodontics, EarlyView.
Abstract Background Reconstruction of cleft‐associated defects in the anterior maxilla is complicated by deficient hard and soft tissues, scarring, and altered anatomy. This case report describes tooth autotransplantation with simultaneous autogenous bone augmentation for replacement of a congenitally absent maxillary lateral incisor. Methods A 20‐year‐

Percutaneous Left Atrial Appendage Closure Using a PFO Occluder After an Incomplete Surgical Ligation

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT The case regards a 73‐year‐old male who was referred for consideration of percutaneous left atrial appendage closure. His left atrial appendage was ligated during prior mitral valve surgery, but was noted to be patent on a recent transesophageal echocardiography. An Amulet device was selected based on CT planning.
