Comparative results were obtained in the experiments conducted on dogs in cranioplasty using allogenic bones, one-piece or small-fragmentized brephoxenotransplants. It was found out that allogenic bones and brephoxenotransplants, when conserved in the solution of 0.2% of formaline and 0.1% of gl. aldehyde, were a perfect material for cranioplasty. These materials ensure a reparative osteogenesis in the recipient's organism after grafting. The process in small-fragmentized brephoxenotransplants is more active and ensures the bone recuperation of the vault of skull in 1.5 years.

Background: The impact of tongue protrusion forces on the formation of malocclusions is well documented in academic literature. In the case of bone dehiscence of the buccal wall in front of the lower frontal teeth, this process may be even more pronounced. Augmentation with 3D customized allogenic bone blocks (CABB) has been proposed as a potential solution for treating such defects.

Background: Given the risks associated with autologous bone transplantation and the limitations of allogeneic bone transplantation, scaffolds in bone tissue engineering that incorporate bioactive peptides are highly recommended. Teriparatide (TPTD) plays a significant role in bone defect repair, although achieving controlled release of TPTD within a bone tissue engineering scaffold remains challenging. This work reports a new approach for treatment of teriparatide using a water-in-oil-in-water (w/o/w) microspheres be equipped on gelatin (GEL)/Poly lactic-glycolic acid (PLGA)/attapulgite (ATP) scaffold.

Myeloproliferative neoplasm-associated myelofibrosis is a clonal stem cell process characterized by pronounced bone marrow fibrosis associated with extramedullary hematopoiesis and splenomegaly. Allogeneic hematopoietic stem cell transplantation (allo-HSCT) represents the only curative treatment leading to bone marrow fibrosis regression. Here we provide an in-depth skeletal characterization of myelofibrosis patients before and after allo-HSCT utilizing clinical high-resolution imaging, laboratory analyses, and bone biopsy studies.

Diseases and injuries can cause significant bone loss, leading to increased medical expenses, decreased work efficiency, and a decline in quality of life. Bone tissue engineering (BTE) is gaining attention as an alternative to autologous and allogeneic transplantation due to the limited availability of donors. Biomaterials represent a promising strategy for bone regeneration, and their design should consider the three key processes in bone tissue engineering: osteogenesis, bone conduction, and bone induction.

Cell salvage (CS) is a tool where autologous blood lost during surgery is collected and recycled with anticoagulation, centrifugation to separate red blood cells, and washing to be reinfused back to the patient. The purpose of this study was to investigate our experience with CS in pelvic and acetabular surgery and its relationship to perioperative transfusion requirements.
