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). ...

Biometrics based authentication provides various advantages over other authentication methods, it has replaced the password based authentication and token based authentication. Biometrics plays a major role in Automated Teller Machine (ATM) system, E-Commerce, Online banking, Passports. The growth in electronic transactions has been increased tremendously; there is a greater demand for fast and...

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...

background in rhinoplasty, functional and cosmetic problems of the nose are corrected. these problems cause imbalance between the nasal subunit and face. throughout these deformities, there are 4 variants, so there is a need for careful preoperative evaluation either for treatment or prevention of the occurrence. according to functional and aesthetic effects of these variables in rhinoplasty, e...

Human vaults are the largest cytoplasmic ribonucleoprotein and are overexpressed in cancer cells. Vaults reportedly function in the extrusion of xenobiotics from the nuclei of resistant cells, but the interactions of xenobiotics with the vault-associated proteins or non-coding RNAs have never been directly observed. In the present study, we show that vault RNAs (vRNAs), specifically the hvg-1 a...

Deep inside a mountain on the island of Spitzbergen within the Arctic Circle, the world's first Global Seed Vault was launched last month as the ultimate in safe repository for plant material from seed stores around the world that may be subject to climate change or other unpredictable catastrophies. Every nation has been invited by the Norwegian government to place seeds in its vault. The seed...
