The material properties of cortical bone from the diaphyses of long bones (e.g., the femur and tibia) vary by direction, such that bone is stiffer and stronger along its long axis. This configuration improves the abilities of these structures to resist axial compressive loads coupled with bending. As in long bones, cortical bone from the cranial vault is subject to mechanical loads from various...

Bones of the cranial vault appear to be highly conserved among tetrapod vertebrates. Moreover, bones identified with the same name are assumed to be evolutionarily homologous. However, recent developmental studies reveal a key difference in the embryonic origin of cranial vault bones between representatives of two amniote lineages, mammals and birds, thereby challenging this view. In the mouse,...

PURPOSE To investigate the effectiveness of fibrin glue in comparison with polyglycolic acid suture to promote the closure of rabbit's vaginal vault, after abdominal hysterectomy. METHODS Twenty female, adults, New Zealand rabbits, were submitted to abdominal hysterectomy and randomly distributed to polyglycolic acid suture (G-PA / n=10) or fibrin glue closure of vaginal vault (G-FG / n=10). ...

objective: urogynecologists are constantly looking for simple, safe and effective ways to cure vaginal apex prolapse. the aim of this study was to evaluate the results of posterior intravaginal slingplasty (pivs). materials and methods : a total of 38 patients with advanced vaginal apical prolapse underwent posterior intravaginal slingplasty in vali-e-asr hospital in tehran. in this clinical tr...
