Polarization and Characterization of M1 and M2 Human Monocyte-Derived Macrophages on Implant Surfaces.

Foreign body reaction (FBR), an immune-mediated complex healing process, plays a crucial role in integrating implants into the body. Macrophages, as the first line of immune system interaction with implant surfaces, play a bidirectional role in modulating the inflammation-regeneration balance. For a deep understanding and the evaluation of the reactions between implant materials and immune responses, reliable in vitro methods and protocols are pivotal.

Enhanced Experimental Setup and Methodology for the Investigation of Corrosion Fatigue in Metallic Biodegradable Implant Materials.

Biodegradable implants as bone fixations may present a safe alternative to traditional permanent implants, reducing the risk of infections, promoting bone healing, and eliminating the need for removal surgeries. Structural integrity is an important consideration when choosing an implant material. As a biodegradable implant is being resorbed, until the natural bone has regrown, the implant material needs to provide mechanical stability.

Competency-based training and supervision: development of the WHO-UNICEF Ensuring Quality in Psychosocial and Mental Health Care (EQUIP) initiative.

Globally, there has not been a standardised approach to ensure that the growing number of people who are not licensed clinicians but are delivering psychological interventions and mental health services have the competencies to deliver those interventions and services safely. Therefore, WHO and UNICEF developed Ensuring Quality in Psychosocial and Mental Health Care (EQUIP). EQUIP is a free resource with a digital platform that can be used to guide competency assessment.

Conventionally and digitally fabricated removable complete dentures: manufacturing accuracy, fracture resistance and repairability.

Objectives: Conventionally and digitally manufactured removable complete dentures with different dentition forms were examined for manufacturing accuracy (trueness, precision), fracture forces under torsional loading and subsequent repairability.

Methods: A total of 90 mandibular prostheses were manufactured. Ten were made using the injection molding technique and finished with prefabricated teeth.

Existence and convergence of the length-preserving elastic flow of clamped curves.

We study the evolution of curves with fixed length and clamped boundary conditions moving by the negative -gradient flow of the elastic energy. For any initial curve lying merely in the energy space we show existence and parabolic smoothing of the solution. Applying previous results on long-time existence and proving a constrained Łojasiewicz-Simon gradient inequality we furthermore show convergence to a critical point as time tends to infinity.
