Innovative molecular methods for fish species differentiation
… method for various market-relevant fish species have been developed. A DNA microarray was established using a set of 100 universal oligonucleotide probes. DNA probe signal patterns were observed to be speciesspecific, enabling species identification of unknown fish samples by comparing …

AN ANALYSIS OF LOBLOLLY PINE AND SHORTLEAF PINE HYBRIDIZATION USING CHROMATOGRAPHY AND GEOGRAPHIC INFORMATION SYSTEMS: A CASE STUDY IN EAST TEXAS
<p>East Texas forests contain three native pine species known to hybridize when site conditions are suitable. Due to increased gene flow from hybridization, quantifying hybridization spatially is a growing concern as southeastern United States pine forests are increasingly influenced by improved …

Cell Wall/Surface Proteome of Candida albicans: its Application in Rapid Identification of Yeast Species by Mass Signature and Characterization by in vitro and in vivo Chemical Labelings
… fungal cells yielded mass signatures for rapid species differentiation, strain grouping and yeast morphogenesis monitoring. Cell surface biotinylations at low temperature (4°C), enzymatic digestion of the intact fungal cell surface proteins ("whole cell shaving"), biotin-avidin affinity …

Seasonal trends in separability of leaf reflectance spectra for Ailanthus altissima and four other tree species
… the spectral separability of the invasive species Ailanthus altissima, commonly called tree of heaven, and four other native species. Leaves were collected from Ailanthus and four native tree species from May 13 through August 24, 2008, and spectral reflectance factor measurements were …

Walleye dermal sarcoma virus Orf C: a potential oncolytic therapy
… Say was reviewed. Five previously described species are recognized as valid: affinis, foveolatus, hirsutus, humeralis, and maculosus. One new species, tumulosus, from Texas is described as new. The following new synonymy is proposed: longior LeConte 1856 (= affinis LeConte 1856) and albidus …

The use of histological methods to distinguish between burned remains of human and non-human bone
… bone samples collected from four different species namely; humans (Homo sapiens), pig (Sus scrofa), wildebeest (Connochaetes gnou) and cow (Bos taurus). Unburned samples were compared to bone samples burned at 600°C, 700°C, 800°C and 900°C in a muffle furnace for 20 minutes. Bone samples …

Psychrophilic and psychrotrophic Clostridium spp. associated with meat spoilage
… studied with respect to their identification, differentiation and taxonomy, as well as spoilage aetiology. The aetiological study was conducted to establish whether a causal relationship exists between psychrophilic and psychrotrophic clostridia and the production of abundant gas in …

The Maintenance of Genetic Variation by Environmental Selection
… genetic variants can be inherited. For a species in natural environments, genetic variation is generated by mutation, eliminated by genetic drift or selective sweep, and maintained by balancing selection that favors different alleles in different environments or time. In my dissertation, I …

PROTEIN AND OPIOID ANALYSIS BY CAPILLARY ELECTROPHORESIS WITH LASER INDUCED FLUORESCENCE AND MASS SPECTROMETRY DETECTION
… was only able to determine the total morphine species concentration, whereas the new CE-ESI-QTOF-MS method described herein allowed for species differentiation in addition to total morphine determination. By this method, it was found that M3G and M6G metabolites were present, on average, in a …

Modelling cannibalism and inter-species predation for the Cape hake species Merluccius capensis and M. paradoxus
… and harvests two morphologically similar species, the shallow- water Cape hake Merluccius capensis and the deep-water Cape hake M. paradoxus. Since 1948, annual catches have exceeded 50 000 tons and the current total allowable catch (TAC) is about 150 000 tons, a quantity informed by …

A morphological and physiological classification of Spirilla
… devise a more satisfactory classification of the species, the type strains of 20 marine and fresh-water species of the genus Spirillum, plus additional strains of S. gracile, S. itersonii, S. serpens, and S. volutans, and 6 un-named strains of spirilla, were subjected to over 90 physiological …

The Role of NADPH Oxidase in ROS Mediated Differentiation
… pathway. Data from our lab shows PrE differentiation is accompanied by an increase in reactive oxygen species (ROS), which induces a conformational change in Nucleoredoxin preventing its ability to bind and inhibit Dishevelled. This in turn positively impacts on the WNT/β- catenin …
