Introduction: The failure of closure of the dorsal wall of the sacral canal (SC) has been known since the eve of modern osteology, appearing in prehistoric times.Variants include partial or complete absence of the dorsal wall of the SC.SC presents a pathway for minimally invasive therapeutic and diagnostic procedures for spinal diseases and for ens

Successful osseointegration involves the biological behavior of bone marrow stem cells (BMSCs) on an implant surface; however, the role of BMSC-derived extracellular vesicles (EVs)/exosomes in osseointegration is little known.This study aimed to: (i) explore the interaction force between exosomes (Exo) and cells on a titanium surface; (ii) discuss

Abstract The water-lubricated bearings are usually the state of turbulent cavitating flow under high-speed conditions.And the distribution of cavitation bubbles and the interface effect between the two phases have not been included in previous studies on high-speed water-lubricated bearings.In order to study the influence of interface effect and ca

Abstract Understanding what makes a community vulnerable to invasion is integral to the successful management of invasive species.Our understanding of how characteristics of resident plant interactions, such as the network architecture of interactions, can affect the invasibility of plant communities is limited.Using a simulation model, we tested h
