Preparation of Ag-Metal organic frameworks-loaded Sodium Alginate Hydrogel for the treatment of periodontitis.

Periodontitis, a common chronic inflammatory condition caused by bacteria, leads to loss of attachment, resorption of alveolar bone, and ultimately tooth loss. Therefore, reducing bacterial load and fostering alveolar bone regeneration are essential components in the treatment of periodontitis. In this study, we prepared smaller-sized Ag-Metal Organic Frameworks (Ag@MOF) and loaded with sodium alginate (Alg) hydrogel for periodontitis treatment.

Hereditary diffuse gastric cancer is characterized by an increased risk of diffuse gastric cancer and lobular breast cancer, and is caused by pathogenic germline variants of E-cadherin and -E-catenin, which are key regulators of cell-cell adhesion. However, how the loss of cell-cell adhesion promotes cell dissemination remains to be fully understood. Therefore, a three-dimensional computer model was developed to describe the initial steps of diffuse gastric cancer development.

Objectives: To use finite element (FE) modeling and in vivo optical coherence tomography (OCT) imaging to explore the effect of ciliary muscle traction on optic nerve head (ONH) deformation during accommodation.
Methods: We developed a FE model to mimic the ciliary muscle traction during accommodation, and varied the stiffness of the sclera, choroid, Bruch's membrane (BM), prelaminar neural tissue and lamina cribrosa (LC) to assess their effects on accommodation-induced ONH strains. To validate the FE model, OCT images of the right eyes' ONHs from 20 subjects (25 ± 1.
Conceptual foundations of a REFRAME-based approach to discriminate across total knee implant designs based on the positions of functional centres of rotation.

In modern knee arthroplasty, surgeons increasingly aim for individualised implant selection based on data-driven decisions to improve patient satisfaction rates. The identification of an implant design that optimally fits to a patient's native kinematic patterns and functional requirements could provide a basis towards subject-specific phenotyping. The goal of this study was to achieve a first step towards identifying easily accessible and intuitive features that allow for discrimination between implant designs based on kinematic data.

Composite gels are a type of soft matter, which contains a continuous three-dimensional crosslinked network and has been embedded with non-gel materials. Compared to pure gels, composite gels show high flexibility and tunability in properties and hence have attracted extensive interest in applications ranging from cancer therapy to tissue engineering. In this study, we incorporated triethylenetetramine (TETA)-functionalized cobalt ferrite nanoparticles (ANPs) into a hydrogel consisting of sodium alginate (SA) and methyl cellulose (MC), and examined the resulting composite gels for controlled drug release.
