The author performed immunohistochemical staining of blood group antigen (BGA), CEA, BMG, Leu-M1 and H-Ag on 43 patients with primary superficial bladder tumor to evaluate the malignant potential of bladder tumor. There were no obvious relationships among reactivities to BGA, CEA, BMG, Leu-M1 and H-Ag in identical tissue. Although BGA, CEA and Leu-M1 could be used individually as indicators of ...

OBJECTIVE Presentation of an experience in benchmarking in 13 university Spanish thoracic surgery services. METHODS The minimum basic data set (MBDS) for hospitalization, corresponding to 2007, including all registered hospital discharges, was used. The performance of the hospitals was compared using an external reference pattern (SN) and internal average (BMG). Cases were chosen in which a m...

Background: In several conditions we have face cranial bone defects. Reconstruction of these defects remains one of the most challenging problems encountered by craniofacial surgeons. Objective: To evaluate bone repair in cranial bone defects by use of an implant made of octacalcium phosphate in combination with bone matrix gelatin (OCP/BMG). Methods: We used 40, 5–6-week-old male Sprague-Dawle...

The mechanical properties of bulk metallic glasses (BMGs) and their composites have been under intense investigation for many years, owing to their unique combination of high strength and elastic limit. However, because of their highly localized deformation mechanism, BMGs are typically considered to be brittle materials and are not suitable for structural applications. Recently, highly-toughen...

The number of processors embedded in high performance computing platforms is growing daily to solve larger and more complex problems. However, as the number of components increases, so does the probability of failure. The logical network topologies must also support the fault-tolerant capability in such dynamic environments. This paper presents a self-healing mechanism to improve the fault-tole...

It is known that the glass forming-ability (GFA) of bulk metallic glasses (BMGs) can be greatly enhanced via minor element additions. However, direct evidence has been lacking to reveal its structural origin despite different theories hitherto proposed. Through the high-resolution transmission-electron-microscopy (HRTEM) analysis, here we show that the content of local crystal-like orders incre...

A model Zr41.25Ti13.75Ni10Cu12.5Be22.5 (at.%) bulk metallic glass (BMG) is selected to explore the structural evolution on the atomic scale with decreasing temperature down to cryogenic level using high energy X-ray synchrotron radiation. We discover a close correlation between the atomic structure evolution and the strength of the BMG and find out that the activation energy increment of the co...

Respondents from eight Korean and U.S. higher education institutions were surveyed as to their knowledge and experience with various forms of computer malware. The surveys provide insight into knowledge of rootkits that have become coffee lounge discussion following the once secretive Sony rootkit news break in late 2005 and then the rash of accusations and acknowledgements of other rootkits th...

BACKGROUND Urethral stricture disease is prevalent, and many surgical techniques have been developed to treat it. Currently, urethroplasty for bulbar strictures implies ventral or dorsal stricturotomy and a buccal mucosa graft (BMG) patch. OBJECTIVE To describe the surgical approach of the ventral patch BMG urethroplasty for proximal bulbar urethral stricture and to analyze 11 consecutive cas...
