While adequate, catgut and the more recently developed regenerated collagens have inherent disadvantages common to many complex natural substances, particularly variability in composition and properties.A new synthetic absorbable suture has been developed from polyglycolic acid .This material was chosen after testing a wide variety of polymers for the appropriate absorbability behavior in animals and for the required physical and mechanical properties. packaging and industrial products applications Polyglycolic Acid (PGA) Resin The Pursuit of Excellence MPa PGA 100 80 60 40 20 0 1 3 5 7 9 11 13 15 17 19 21 23 25 Days Biodegradation (%) Tested by ISO14855 standards PGA Cellulose 1,000 100 10 1 O2TR (cm3/m2•day•atm, 30°C, 80%RH) WVTR Researchers have extensively investigated the potential of PLGA nanoparticles for target specific and controlled delivery of various micro and macromolecules including drugs, peptides, proteins, monoclonal antibodies, growth factors and DNA in multifarious biomedical applications like neurodegenerative and cardiovascular diseases, inflammatory disorders, cancer and other dreadful health disorders. For this, the PECNs were produced initially by polyelectrolytic complexation (bottom-up method) and subsequently subjected to ultra-high pressure homogenization-UHPH (top-down method). Thirty-two mice were analyzed over a 7-week period with respect to volume, weight and microscopic evaluations with hematoxylin and eosin (H&E), epidermal growth factor (EGF) and vascular endothelial growth factor (VEGF) staining.ResultsThe volume and weight were maintained at 80% and 83%, respectively, in the ADM/HA filler group and 56.5% and 49.7%, respectively, in the fat-grafted group by the 7th week. For example, PGA sutures can be completely absorbed in the body within 4-6 months. Polyglycolic acid (PGA) and poly lactic- co -glycolic acid (PLGA) sutures were introduced in the 1970s as the first synthetic absorbable synthetic sutures and are still used today. It is difficult to obtain PGA porous scaffolds with controllable morphology as well as outstanding mechanical properties without toxic solvents. Micronized acellular dermal matrix (ADM) has been considered as a stable, biocompatible soft tissue coverage material that can be used as a volume filler. biodegradability and biocompatibility.
