A Large Volume Striped Bass Incubation Chamber: Design And Comparison With A Traditional Method, Chris Harper Sep 2008

A Large Volume Striped Bass Incubation Chamber: Design And Comparison With A Traditional Method, Chris Harper

All Theses

I conducted a comparative study of a new jar design (experimental chamber) with a standard egg incubation vessel (McDonald jar). Experimental chambers measured 0.4 m in diameter by 1.3 m in height and had a volume of 200 L. McDonald hatching jars measured 16 cm in diameter by 45 cm in height and had a volume of 6 L. Post-hatch survival was estimated at 48, 96 and 144 h. Stocking rates resulted in an average egg density of 21.9 eggs ml-1 (range = 21.6 - 22.1) for McDonald jars and 10.9 eggs ml-1 (range = 7.0 - 16.8) for experimental …

Evolution Of The Holozoan Ribosome Biogenesis Regulon, Seth J. Brown, Michael D. Cole, Albert J. Erives Sep 2008

Evolution Of The Holozoan Ribosome Biogenesis Regulon, Seth J. Brown, Michael D. Cole, Albert J. Erives

Dartmouth Scholarship

The ribosome biogenesis (RiBi) genes encode a highly-conserved eukaryotic set of nucleolar proteins involved in rRNA transcription, assembly, processing, and export from the nucleus. While the mode of regulation of this suite of genes has been studied in the yeast, Saccharomyces cerevisiae, how this gene set is coordinately regulated in the larger and more complex metazoan genomes is not understood. Here we present genome-wide analyses indicating that a distinct mode of RiBi regulation co-evolved with the E(CG)-binding, Myc:Max bHLH heterodimer complex in a stem-holozoan, the ancestor of both Metazoa and Choanoflagellata, the protozoan group most closely related to animals. These …

Markham, Frederic Beaudoin, Johnathan A. Napier, Jean-Denis Faure

Department of Biochemistry: Faculty Publications

Very-long-chain fatty acids (VLCFAs) are synthesized as acyl-CoAs by the endoplasmic reticulum-localized elongase multiprotein complex. Two Arabidopsis genes are putative homologues of the recently identified yeast 3-hydroxy-acyl-CoA dehydratase (PHS1), the third enzyme of the elongase complex. We showed that Arabidopsis PASTICCINO2 (PAS2) was able to restore phs1 cytokinesis defects and sphingolipid long chain base overaccumulation. Conversely, the expression of PHS1 was able to complement the developmental defects and the accumulation of long chain bases of the pas2–1 mutant. The pas2–1 mutant was characterized by a general reduction of VLCFA pools in seed storage triacylglycerols, cuticular waxes, …

Muscular Strength And Body Composition Comparison Between The Charlotte-Mecklenburg Fire And Police Departments, Robert W. Boyce‡, Satya Ciulla*, Glenn R. Jones‡, Edward L. Boone‡, Steven M. Elliott‡, Clarice S. Combs‡

International Journal of Exercise Science

Firefighters and police have different physical job requirements and selection processes. Firefighters have on-duty exercise time and police do not. This could affect body composition and strength. The purpose of this investigation was to compare body composition and bench press strength between firefighters and police officers in the Charlotte-Mecklenburg departments. Current 2006 fitness records were analyzed to compare firefighters and police (N = 2330). Variables included: gender, age, body mass, percent body-fat, fat mass, lean mass, bench press strength, bench press/lean mass, bench press/body mass, and percent that were obese. Significant (p ≤ 0.05) differences were found between male firefighters …


Lis1 And Ndel1 Influence The Timing Of Nuclear Envelope Breakdown In Neural Stem Cells, Sachin Hebbar, Mariano T. Mesngon, Aimee M. Guillotte, Bhavim Desai, Ramses Ayala, Deanna S. Smith Sep 2008

Lis1 And Ndel1 Influence The Timing Of Nuclear Envelope Breakdown In Neural Stem Cells, Sachin Hebbar, Mariano T. Mesngon, Aimee M. Guillotte, Bhavim Desai, Ramses Ayala, Deanna S. Smith

Faculty Publications

Lis1 and Ndel1 are essential for animal development. They interact directly with one another and with cytoplasmic dynein. The developing brain is especially sensitive to reduced Lis1 or Ndel1 levels, as both proteins influence spindle orientation, neural cell fate decisions, and neuronal migration. We report here that Lis1 and Ndel1 reduction in a mitotic cell line impairs prophase nuclear envelope (NE) invagination (PNEI). This dyneindependent process facilitates NE breakdown (NEBD) and occurs before the establishment of the bipolar spindle. Ndel1 phosphorylation is important for this function, regulating binding to both Lis1 and dynein. Prophase cells in the ventricular zone (VZ) …

To Love Your Neighbor: A Christian Perspective On The Study Of Microbiology And Immunology, Joy Doan Sep 2008

To Love Your Neighbor: A Christian Perspective On The Study Of Microbiology And Immunology, Joy Doan

Faith Learning Integration Papers

I have been blessed with enough of a sense of adventure to have experienced the awe-inspiring beauty of a rain forest at night, the top of Half Dome at Yosemite National Park, the sheer cliffs and rushing waters of the Narrows at Zion National Park, Plateau Point—which seems suspended in the Grand Canyon, and the top of a 14,000-foot peak in the Rocky Mountains of Colorado. These are the types of places about which one of the characters in Robert Pirsig’s Zen and the Art of Motorcycle Maintenance observes, “This is the hardest stuff in the world to photograph. You …

Next Generation Dna Sequencing And The Birth Of A Golden Era For Microbial Ecology Sep 2008

Next Generation Dna Sequencing And The Birth Of A Golden Era For Microbial Ecology

Core for Applied Genomics and Ecology (CAGE)

In 2005, a breakthrough technology was Announced that provided a quantum leap In DNA sequencing capacity.

This technology differed from the Sanger method In many ways:
1. Eliminates cloning—completely circumvents cloning bias
2. Uses bead technology—DNA templates are attached to sepharose beads
3. Relies on pyrosequencing chemistry—synthesis is sequential not partial
4. Parallelizes the sequencing process—hundreds of thousands of beads can be sequenced in parallel

The bottom line: it makes production-scale sequencing available to the common man.


Seasonal Variations In Nutrient Concentrations And Speciation In The Chena River, Alaska, Yihua Cai, Laodong Guo, Thomas A. Douglas, Terry E. Whitledge Sep 2008

Seasonal Variations In Nutrient Concentrations And Speciation In The Chena River, Alaska, Yihua Cai, Laodong Guo, Thomas A. Douglas, Terry E. Whitledge

Faculty Publications

To better understand the seasonal controls on nutrient abundances, speciation, and fluxes in a watershed underlain by discontinuous permafrost, we collected water samples biweekly from the Chena River during 2005-2006 to measure inorganic and organic N, P, and Si in dissolved and particulate phases. Nitrate concentrations were low (8-14 mu M) during the winter and summer dry seasons but were elevated during the spring freshet (15-24 mu M). Ammonium varied from 8 to 13 mu M during the winter but dropped dramatically during the ice-open season to 0.1-3 mM. Phosphate was very low throughout the year (ranging from 0.03 to …


Metabolic Engineering Of A Thermophilic Bacterium To Produce Ethanol At High Yield, A. Joe Shaw, Kara K. Podkaminer, Sunil G. Desai, John S. Bardsley, Stephen R. Rogers, Philip G. Thorne, David A. Hogsett, Lee R. Lynd Sep 2008

Metabolic Engineering Of A Thermophilic Bacterium To Produce Ethanol At High Yield, A. Joe Shaw, Kara K. Podkaminer, Sunil G. Desai, John S. Bardsley, Stephen R. Rogers, Philip G. Thorne, David A. Hogsett, Lee R. Lynd

Dartmouth Scholarship

We report engineering Thermoanaerobacterium saccharolyticum, a thermophilic anaerobic bacterium that ferments xylan and biomass-derived sugars, to produce ethanol at high yield. Knockout of genes involved in organic acid formation (acetate kinase, phosphate acetyltransferase, and L-lactate dehydrogenase) resulted in a strain able to produce ethanol as the only detectable organic product and substantial changes in electron flow relative to the wild type. Ethanol formation in the engineered strain (ALK2) utilizes pyruvate:ferredoxin oxidoreductase with electrons transferred from ferredoxin to NAD(P), a pathway different from that in previously described microbes with a homoethanol fermentation. The homoethanologenic phenotype was stable for >150 generations …


Intraretinal Signaling By Ganglion Cell Photoreceptors To Dopaminergic Amacrine Neurons, Dao-Qi Zhang, Kwoon Y. Wong, Patricia J. Sollars, David M. Berson, Gary E. Pickard, Douglas G. Mcmahon Sep 2008

Intraretinal Signaling By Ganglion Cell Photoreceptors To Dopaminergic Amacrine Neurons, Dao-Qi Zhang, Kwoon Y. Wong, Patricia J. Sollars, David M. Berson, Gary E. Pickard, Douglas G. Mcmahon

School of Veterinary and Biomedical Sciences: Faculty Publications

Retinal dopaminergic amacrine neurons (DA neurons) play a central role in reconfiguring retinal function according to prevailing illumination conditions, yet the mechanisms by which light regulates their activity are poorly understood. We investigated the means by which sustained light responses are evoked in DA neurons. Sustained light responses were driven by cationic currents and persisted in vitro and in vivo in the presence of L-AP4, a blocker of retinal ON-bipolar cells. Several characteristics of these L-AP4-resistant light responses suggested that they were driven by melanopsin-expressing intrinsically photosensitive retinal ganglion cells (ipRGCs), including long latencies, marked poststimulus persistence, and a peak …

Aquatic Ecosystem Response To Storm Water Abatement Measures In The Ravines Of The Gvsu Allendale Campus: Establishment Of Base-Line Biological Condition, Eric Snyder, Jason Nelson, Jason Drogowski, Michelle Harju

Technical Reports

The ravine tributary streams surrounding Grand Valley State Universities Allendale campus represent unique and understudied ecosystems, worthy of significant restoration efforts and of long-lasting protection. They are variously affected by storm water runoff, representing a spectrum from severely impacted to relatively pristine. Quantitative macroinvertebrate samples taken from six streams in late June 2007, indicated that insect diversity was positively correlated to ammonium (p=0.057), while total abundance was negatively correlated to phosphate and chlorophyll-a concentration (n.s.). In addition, phosphate, nitrate, sulfate and iron concentrations were elevated in streams that experience significant storm-water runoff and these streams also tended to have …
