| effect of temperature and yeast extract on microbial respiration of sediments from a shallow coastal subsurface and vadose zone. | as a part of our study on microbial heterogeneity in subsurface environments, we have examined the microbial respiration of sediment samples obtained from a coastal site near oyster, va. the sediments at the site are unconsolidated, fine to coarse beach sand and gravel. a columbus instruments micro-oxymax respirometer was used to measure the rate of carbon dioxide (co2) production during the respiration of the sediment samples. the rate of respiration of the sediment samples ranged from 0.035-0. ... | 1996 | 8669920 |
| modeling regulatory networks at virginia tech. | the life of a cell is governed by the physicochemical properties of a complex network of interacting macromolecules (primarily genes and proteins). hence, a full scientific understanding of and rational engineering approach to cell physiology require accurate mathematical models of the spatial and temporal dynamics of these macromolecular assemblies, especially the networks involved in integrating signals and regulating cellular responses. the virginia tech consortium is involved in three specif ... | 2003 | 14583117 |
| the diagnostic accuracy of serologic markers in children with ibd: the west virginia experience. | to assess the sensitivity/specificity of the serologic markers: perinuclear antineutrophil cytoplasmic antibody (panca) and anti-saccharomyces cerevisiae antibody (asca) in children diagnosed with inflammatory bowel disease (ibd), living in west virginia. | 2005 | 16082274 |
| phaeohyphomycosis in a free-living eastern box turtle (terrapene carolina carolina). | a free-ranging eastern box turtle (terrapene carolina carolina) was referred to the wildlife center of virginia with a three-month history of marked swelling of the right hind limb initially diagnosed as chromomycosis by histopathology. hematology revealed severe anemia (9%), leukocytosis (12.8 cells x 10(3)/microl), heterophilia (6.14 cells x 10(3)/microl), and monocytosis (0.51 cells x 10(3)/microl). gross necropsy revealed a firm, encapsulated 3 x 1 cm subcutaneous mass filled with dark brown ... | 2006 | 17255461 |
| reproductive health of bass in the potomac, u.s.a., drainage: part 2. seasonal occurrence of persistent and emerging organic contaminants. | the seasonal occurrence of organic contaminants, many of which are potential endocrine disruptors, entering the potomac river, usa, watershed was investigated using a two-pronged approach during the fall of 2005 and spring of 2006. passive samplers (semipermeable membrane device and polar organic chemical integrative sampler [pocis]) were deployed in tandem at sites above and below wastewater treatment plant discharges within the watershed. analysis of the samplers resulted in detection of 84 of ... | 2009 | 19108592 |
| Effects of watershed densities of animal feeding operations on nutrient concentrations and estrogenic activity in agricultural streams. | Application of manures from animal feeding operations (AFOs) as fertilizer on agricultural land can introduce nutrients and hormones (e.g. estrogens) to streams. A landscape-scale study was conducted in the Shenandoah River watershed (Virginia, USA) in order to assess the relationship between densities of AFOs in watersheds of agricultural streams and in-stream nutrient concentrations and estrogenic activity. The effect of wastewater treatment plants (WWTPs) on nutrients and estrogenic activity ... | 2011 | 22088420 |
