Granular cell tumor rarely occurs in the thyroid. This case report describes the cytologic features of a granular cell tumor seen in a fine needle aspirate obtained from a 27-year-old woman with a gradually enlarging thyroid nodule. The aspirate showed single as well as syncytial clusters of cells with abundant granular cytoplasm. The differential diagnosis in this case included granular cell tumor, Hurthle cell lesion/neoplasm, and a histiocytic reparative process. Immunohistochemical studies, including S-100 protein and CD68, performed on a cell block preparation were helpful in supporting the diagnosis. Diagn.

Background: During septoplasty surgery, the formation of dead space between the mucosal flaps must be minimized to prevent septal hematoma and promote healing. Historically, this has been achieved by using techniques such as nasal packing or the continuous septal quilting or whip suturing. This study presents the first clinical results using a septal stapling device that uses bioresorbable staples to achieve mucoperichondrial flap coaptation during septoplasty. Methods: The septal stapler was used in 24 subjects. The primary outcome measure was whether septal coaptation was accomplished 1 week postoperatively. The extent of tissue reaction at the site of staple placement was also evaluated. Results: In all subjects, coaptation with septal staples was successfully accomplished with no septal hematoma formation. At 1 week follow-up, there was either no (79%) or minimal (21%) tissue reaction at the site of staple placement. Conclusion: The use of bioresorbable staples appears to be a safe, efficient, and effective alternative to other methods used for mucoperichondrial flap coaptation in septoplasty surgery.

Within the Western Interior Basin of North America, hundreds of small carbonate mounds associated with Late Cretaceous hydrocarbon emissions or seeps form the most extensively distributed occurrence of fossil seep mounds that is known, the Tepee Buttes. Analysis of the stratigraphic literature for the basin reveals that Tepee Butte formation occurred intermittently over a 10-m.yr. period within a narrowly restricted paleogeographic region. The modern geographic distribution of the Tepee Buttes is constrained roughly to between 101°30″ and 105°30″W longitude and ranges from the northern Black Hills southward into southern Colorado. Four discernible intervals of seep activity are identified over a time span of 10 m.yr., from late Middle Campanian (78.7 Ma) through the Early Maastrichtian (69.1 Ma). Comparisons of the paleobiogeography of the Tepee Buttes to subsurface structures, basinal subsidence patterns, and shoreline position indicate an association between mound formation, western shoreline migration, and changes in basin tectonics. Initiation of the Tepee Butte formation is concurrent with changes in the basin tectonics and the subsequent eastward shift of maximum subsidence and sediment deposition within the basin. Mound distribution is basinward of the loci of maximum subsidence and is inferred to delineate the forebulge region of the basin during the period of Tepee Butte formation. Each determined interval of mound formation can be tied to migration of the basin's western shoreline, with mound formation starting at maximum transgressive phases and ending at maximum regressive phases. It is postulated that shoreline migration altered sediment loading across the basin, affecting the degree of flexure of the forebulge region and thus affecting hydrocarbons emissions and mound formation. © 2010 by The University of Chicago.

Senter's strategy of arguing against creationism using their own methodology focused on demonstrating a morphological continuum between birds and nonavian dinosaurs using classical multidimensional scaling (CMDS), a method used by some creationists to assign species to assist in the detection of phylogenetic 'discontinuities.' Because creationists do not typically use CMDS in the manner Senter used it, his results were re-examined using 'distance correlation,' a method used to assign species to 'created kinds.' Distance correlation using Senter's set of taxa and characters supports his conclusion of morphological continuity, but other sets of taxa with more characters do not. These results lessen the potential impact that Senter's strategy might have on creationism; however, it is possible that future fossil discoveries will provide stronger support for morphological continuity between dinosaurs and birds. © 2011 The Author.

MicroRNAs (miRNAs) are a class of small nonprotein-coding RNAs (ncRNAs) that have been shown to promote the degradation of target messenger RNAs and inhibit the translation of networks of protein-coding genes to control the development of cells and tissues, and facilitate their adaptation to environmental forces. In this chapter, we will discuss recent data that show that miRNAs are an important component of the epigenetic landscape that regulates the transcription as well as the translation of protein-coding gene networks. We will discuss the evidence that implicates miRNAs in both developmental and adult effects of alcohol consumption. Understanding the interactions of this novel class of ncRNAs with the epigenome will be important for understanding the etiology of alcohol teratology and addiction as well as potential new treatment strategies. © 2014 Elsevier Inc.
