There are still a limited number of primary interventions for prevention breast cancer. For women at high risk developing cancer, the most effective intervention is prophylactic mastectomy. This drastic surgical procedure in which mammary epithelial cells that can give rise to cancer completely removed along with surrounding tissue. The goal this protocol demonstrate feasibility minimally invas...

Scaffold-free cartilage engineering techniques may provide a simple alternative to traditional methods employing scaffolds. We previously reported auricular chondrocyte-derived constructs for use in an engineered trachea model; however, the construct generation methods were not reported in detail. In this study, methods for cartilage construct generation from auricular and articular cell source...

Uncemented acetabular components are associated with a significant incidence of polyethylene wear and secondary osteolysis. The new tantalum/polyethylene composite (Hedrocel) acetabular component is designed to reduce the polyethylene wear and to increase the longevity of the acetabular cups. We report our short- term clinical outcome and patient satisfaction following use of an uncemented tant...

Tantalum nitride nanoparticles (NPs) and cubic bixbyite-type Ta2N3 nanocrystals (NCs) were grown in (Ta-N+Al2O3)/Al2O3 periodic multilayers (MLs) after thermal treatment. The MLs were prepared by magnetron deposition at room temperature and characterized using grazing incidence small-angle X-ray scattering (GISAXS), X-ray reflectivity (XRR), grazing incidence X-ray diffraction (GIXRD), secondar...

Scintillations in solid tantalum capacitors are momentarily local breakdowns terminated by a self-healing or conversion to a high-resistive state of the manganese oxide cathode. This conversion effectively caps the defective area of the tantalum pentoxide dielectric and prevents short-circuit failures. Typically, this type of breakdown has no immediate catastrophic consequences and is often con...

A series of triborane and tetraborane analogues have been isolated structurally characterized utilizing chalcogenatoborate ligands Li[BH3(EPh)] (E=S or Se). Thermolysis [Cp*TaCl4] in the presence Li[BH3(SPh)] afforded bimetallic tantallaheteroborane [(Cp*Ta)2(?-?3:?3-B2H4S)(?-?2:?2-SBH3)] (1) hexasulfido trimetallic complex [(Cp*Ta)3(?-S)4(?-SPh)2] (2). Compound 1 is a fused ditantallaheterobor...

OBJECTIVE To evaluate a mixed technique of acetabular reconstruction, which uses trabecular metal in the form of tantalum augments associated with lyophilized bovine xenograft. METHODS Fifteen patients were evaluated prospectively, who underwent acetabular reconstruction with impacted lyophilized bovine xenograft associated with the use of tantalum augments. The main outcome was the failure o...
