Exploring the Influence of Biologically Relevant Ions on the Corrosion Behavior of Biodegradable Zinc in Physiological Fluids.

This work presents a study on the influence of biologically relevant ions on the corrosion of zinc (Zn) in physiological fluids. Electrochemical techniques were used to investigate the degradation of pure Zn exposed to different physiological electrolytes containing chlorides, carbonates, sulfates, and phosphates. The corrosion behavior of Zn in the solutions over a 7-day period was also assessed.

Design, mechanical and degradation requirements of biodegradable metal mesh for pelvic floor reconstruction.

Pelvic organ prolapse is the herniation of surrounding tissue and organs into the vagina and/or rectum and is a result of the weakening of pelvic floor muscles, connective tissue, and fascia. It is widely accepted that 50% of women will develop prolapse, with the prevalence increasing with age, and up to 10-20% of those seek evaluation for their condition. Suture repairs of pelvic floor defects are associated with a high failure rate, and permanent meshes were introduced to reduce the recurrence rate.

Is remaining intervertebral disc tissue interfering with bone generation during fusion of two vertebrae?

Study Design: laboratory research.

Background: Through the increasing number of minimally invasive procedures in spinal fusion surgery, the complete removal of intervertebral disc (IVD) tissue has become more a challenge. Remaining IVD may interfere with the biological process of bone formation.
