Cystic partially differentiated nephroblastoma (CPDN) is extremely rare in adults. Only 2 cases have been documented in the English literature. Herein, we present a third case of CPDN with unique morphological and immunohistochemical features. A 45-year-old man had a multicystic right renal mass, with a maximum diameter of 3 cm on magnetic resonance imaging. Being unable to rule out malignancy,...

The purpose of this study was to evaluate the influence of ceramic surface texture on the wear of rounded rod specimens. Plate specimens were fabricated from zirconia (ZrO2), feldspathic porcelain, and lithium disilicate glass ceramics (LDG ceramics). Plate surfaces were either ground or polished. Rounded rod specimens with a 2.0-mm-diameter were fabricated from type 4 gold alloy and heat-press...

BACKGROUND The sagittal diameter of the cervical spinal canal is of clinical importance in traumatic, degenerative, and inflammatory conditions. A small canal diameter has been associated with an increased risk of injury; however, there is a lack of reliable normative data on spinal canal diameters in different age groups in the United States population. The purpose of this study was to use dir...

Testate amoebae are common single-celled eukaryotic organisms in aquatic ecosystems. Despite their important role in these ecosystems, and their potential as bioindicators and paleoindicators, they remain poorly studied in Mexico. The major objectives of this study were to: 1) increase knowledge of testate amoebae in Mexico’s tropical lakes, and 2) create a catalog of high-quality scanning elec...

BACKGROUND Extension of a single incision for the purpose of specimen extraction in single-port laparoscopic surgery (SPLS) can undermine the merits of SPLS, either by hurting cosmesis or by increasing wound morbidity. METHODS We retrospectively analyzed the clinical outcomes of patients undergoing SPLS sigmoidectomy, either with transanal specimen extraction (TASE, n = 15) or transumbilical ...

In this chapter we discuss the latest developments in the field of high-pressure freezing (HPF). The Leica HPF machine EM HPM100 is discussed in detail due to significant changes compared to its predecessor model. Its centerpiece is a multipart polymer cartridge which holds the specimen carrier sandwich and guides it automatically through the freezing process until immersed in liquid nitrogen. ...

Three-point bend (TPB) and wedge splitting (WS) tests have been conducted on three different concretes and the specific fracture energy GF determined on the basis of the concept of local fracture energy. The latter is influenced by the free back surface of a notched test specimen, as explained by Hu and Wittmann. Tests on three or four specimen sizes with four notch to depth ratios confirm the ...

Modern optical diagnostics for quantitative characterization of polydisperse sprays and other aerosols which contain a wide range of droplet size encounter difficulties in the dense regions due to the multiple scattering of laser radiation with the surrounding droplets. The accuracy and efficiency of optical measurements can only be improved if the radiative transfer within such polydisperse tu...

Please cite this article in press as: Jang, D., et Int. J. Plasticity (2010), doi:10.1016/j.ijplas.20 We report results of uniaxial compression tests on Zr35Ti30Co6Be29 metallic glass nanopillars with diameters ranging from 1.6 lm to 100 nm. The tested pillars have nearly vertical sidewalls, with the tapering angle lower than 1 (diameter >200 nm) or 2 (diameter 100 nm), and with a flat pillar t...
