Dual‐Targeted Biomimetic MoSe2 Nanozymes for Enhancing Peri‐Implant Soft Tissue Integration

Advanced Science, EarlyView.
A dual‐targeting biomimetic nanozyme, MoSe2@SPMM, selectively targets Staphylococcus aureus and oxidatively stressed macrophages. Near‐infrared activation couples contact‐enhanced photothermal bacterial eradication with reactive oxygen species scavenging to disrupt the pathogenic–immunological amplification loop.

Peri-Implant Soft Tissue in Contact with Zirconium/Titanium Abutments from Histological and Biological Perspectives: A Concise Review

Cells
Dental implants are crucial in contemporary oral rehabilitation, necessitating optimal integration with the surrounding soft tissues for durable success. The attachment between the implant surface and peri-implant mucosa should establish a secure seal to

A second species of non‐crocodyliform crocodylomorph from the Late Triassic fissure deposits of southwestern UK: Implications for locomotory ecological diversity in Saltoposuchidae

The Anatomical Record, EarlyView.
Abstract The Late Triassic–Early Jurassic fissures of the Bristol Channel area (southwest England and south Wales) are renowned for their diverse vertebrate faunas. These assemblages have yielded an array of predominantly small‐bodied forms that are crucial to our understanding of the early evolution of several major tetrapod clades.

The mechanism of labor in nonhuman primates: A look inside

The Anatomical Record, EarlyView.
Abstract While in humans, the flexed position of the fetus and its rotating course down the birth canal are well documented, in other primates the mechanism of labor is unknown. Despite the lack of comparative data, it is commonly assumed that the human obstetric mechanism is unique, and anthropologists have disputed when and why the transition to the ...
