Manipulation Of Prenatal Hormones And Dietary Phytoestrogens During Adulthood Alter The Sexually Dimorphic Expression Of Visual Spatial Memory, Edwin D. Lephart, Trent D. Lund Dec 2001

Manipulation Of Prenatal Hormones And Dietary Phytoestrogens During Adulthood Alter The Sexually Dimorphic Expression Of Visual Spatial Memory, Edwin D. Lephart, Trent D. Lund

Faculty Publications

In learning and memory tasks, requiring visual spatial memory (VSM), males exhibit higher performance levels compared to females (a difference attributed to sex steroid hormonal influences). Based upon the results from our companion investigation, this study examined the influence of prenatal sex steroid hormone manipulations on VSM in adulthood, as assessed in the radial arm maze. Additionally, the influence of dietary soy phytoestrogens (i.e., the presence of high or low estrogen-like compounds present in the animal's diet) on VSM was examined in combination with the prenatal hormonal manipulations. Results: Radial arm maze performance on a phytoestrogen-rich diet: 1) females treated …

Glycoprotein K Specified By Herpes Simplex Virus Type 1 Is Expressed On Virions As A Golgi Complex-Dependent Glycosylated Species And Functions In Virion Entry, T. P. Foster, G. V. Rybachuk, K. G. Kousoulas Dec 2001

Glycoprotein K Specified By Herpes Simplex Virus Type 1 Is Expressed On Virions As A Golgi Complex-Dependent Glycosylated Species And Functions In Virion Entry, T. P. Foster, G. V. Rybachuk, K. G. Kousoulas

Faculty Publications

To facilitate detection of glycoprotein K (gK) specified by herpes simplex virus, a 12-amino-acid epitope tag was inserted within gK domain III. Recombinant virus gKprotC-DIII, expressing the tagged gK, was isolated. This virus formed wild-type plaques and replicated as efficiently as the wild-type KOS virus in Vero cells. Anti-protein C MAb detected high-mannose and Golgi complex-dependent glycosylated gK within cells as well as on purified virions. The gK-null virus ΔgK (gK-/-) entered Vero cells substantially more slowly than the wild-type KOS (gK+/+), while ΔgK virus grown in complementing VK302 cells (gK-/+) entered with entry kinetics similar to those of the …

Herbivore-Mediated Effects On Ecosystem Processes In A Near-Arctic Salt Marsh, Brian Thomas Person Dec 2001

Herbivore-Mediated Effects On Ecosystem Processes In A Near-Arctic Salt Marsh, Brian Thomas Person

Biological Sciences

Herbivores influence, and often regulate energy flow. I investigated interactions between herbivory and the foods on which geese rely while nesting and rearing their broods on the Yukon-Kuskokwim Delta in southwestern Alaska. In a captive Cackling Canada gosling (Branta Canadensis minima) experiment I decoupled the effects of seasonal declines in forage quality and availability on gosling development. An 11% decline in forage quality translated to goslings that were structurally smaller and 100 g lighter at 31 days of age. Forage availability had similar effects on gosling size, and the combined magnitude of these effects are similar to those observed in …

Diets Of Juvenile Flatfishes Near Kodiak Island, Alaska, Brenda A. Holladay Dec 2001

Diets Of Juvenile Flatfishes Near Kodiak Island, Alaska, Brenda A. Holladay

Fisheries

Flathead sole, Pacific halibut, rock sole, and yellowfin sole were found co-existing near Kodiak Island as juveniles (<200 mm) during late summer. Dietary differences were attributed to fish species, size, and depth-sediment characteristics of their habitat. Two to three size classes were assigned within each species. Across all habitats, significant differences in dietary composition, stomach fullness, and diet diversity were found between size classes of different flatfish species. Within a single depth-sediment habitat, flatfishes of different species and size classes ate similar prey. Seven of nine species size classes had similar prey composition across multiple habitats. Significant differences in dietary composition across habitats were detected only for small Pacific halibut and small rock sole. The juvenile flatfishes near Kodiak were opportunistic feeders, and appeared to select habitat based on parameters other than the presence of specific prey taxa.

The Ecology Of Age-1 Copper Rockfish (Sebastes Caurinus) In Vegetated Habitats Of Sitka Sound, Alaska, Michael M. Byerly Dec 2001

The Ecology Of Age-1 Copper Rockfish (Sebastes Caurinus) In Vegetated Habitats Of Sitka Sound, Alaska, Michael M. Byerly

Fisheries

Variables that may indicate habitat quality were measured to assess the relative value of shallow subtidal vegetated habitats to age-1 copper rockfish (Sebastes caurinus). All habitats studied appeared beneficial to fish with respect to the particular variable measured. Relative growth rate was significantly higher in kelp than in other habitats while energy content was highest in eelgrass. Though fish in eelgrass had lower growth rates, they were significantly larger, and had high densities. Mixed kelp and eelgrass habitat was suboptimal with respect to growth and energy content but also had high densities. Fish in mixed habitat moved the least both …

Despite High-Tech Entertainment Age, Books Still Enthrall Young Children, Deidra Jackson Dec 2001

Despite High-Tech Entertainment Age, Books Still Enthrall Young Children, Deidra Jackson

University of Mississippi News

UNIVERSITY, Miss. -- When classic stories such as "Charlotte's Web," "Goodnight Moon," and "The Snowy Day" are passed on from one generation to another, they continue to prove at least one concept unrivaled by CD burners, video games, and other high-tech toys: books stand the test of time. Whether bought as presents or borrowed or purchased to fill idle vacation time before and after the holidays, a traditional page-turner can still hold a child's interest and help establish firm reading habits, said Dr. Martha Chambless, coordinator of elementary education in The University of Mississippi (UM) School of Education's Curriculum and …

A Window To The Past: Macrofossil Remains From An 18,000 Year-Old Buried Surface, Seward Peninsula, Alaska, Victoria Goetcheus Wolf Dec 2001

A Window To The Past: Macrofossil Remains From An 18,000 Year-Old Buried Surface, Seward Peninsula, Alaska, Victoria Goetcheus Wolf

Geosciences

Macrofossil remains and pollen from an 18,000 year old buried surface from the northern Seward Peninsula enable a reconstruction of the full-glacial environment of an upland portion of the Bering Land Bridge. The buried surface represents a dry meadow and herb-rich tundra. Prostrate shrubs were rare on the landscape, but abundant locally. A large and diverse insect fauna populated the surface, preying on the plants and each other. Small mammals and their predators lived on the surface. Large mammals, such as caribou and bison, were present as well. The productivity of the surface was maintained by a continual influx of …

Visual Spatial Memory Is Enhanced In Female Rats (But Inhibited In Males) By Dietary Soy Phytoestrogens, Edwin D. Lephart, Trent D. Lund, Timothy W. West, Lilyan Y. Tian, Lihong H. Bu, Daniel L. Simmons, Kenneth Setchell, Herman Adlercreutz Dec 2001

Visual Spatial Memory Is Enhanced In Female Rats (But Inhibited In Males) By Dietary Soy Phytoestrogens, Edwin D. Lephart, Trent D. Lund, Timothy W. West, Lilyan Y. Tian, Lihong H. Bu, Daniel L. Simmons, Kenneth Setchell, Herman Adlercreutz

Faculty Publications

In learning and memory tasks, requiring visual spatial memory (VSM), males exhibit superior performance to females (a difference attributed to the hormonal influence of estrogen). This study examined the influence of phytoestrogens (estrogen-like plant compounds) on VSM, utilizing radial arm-maze methods to examine varying aspects of memory. Additionally, brain phytoestrogen, calbindin (CALB), and cyclooxygenase-2 (COX-2) levels were determined. Results: Female rats receiving lifelong exposure to a high-phytoestrogen containing diet (Phyto-600) acquired the maze faster than females fed a phytoestrogen-free diet (Phyto-free); in males the opposite diet effect was identified. In a separate experiment, at 80 days-of-age, animals fed the Phyto-600 …

Abundance And Ecology Of Martens (Martes Americana) In Interior Alaska, Brad Shults Dec 2001

Abundance And Ecology Of Martens (Martes Americana) In Interior Alaska, Brad Shults

Biological Sciences

I studied marten (Martes americana) abundance and ecology in the Yukon-Charley Rivers National Preserve during 1991-1993. Using a multiple sample, mark-recapture estimator, I estimated marten densities to be 0.69, 0.41, and 0.45 martens/km² during each August for 1991-1993, respectively. Density estimates were derived with the boundary-strip method to address the edge effect inherent in live-trapping studies. During the study, marten density declined 43% between 1991 and 1992 and remained low during 1993. I hypothesize that a decline in primary prey (i.e., microtine rodents) and increased environmental stress (i.e., cold temperatures and snow cover) contributed significantly to the decline in marten …

Role Of Wetlands And Endogenous Factors On Incubation Behavior Of Nesting Spectacled Eiders On The Yukon-Kuskokwim Delta, Alaska, William Todd O'Connell Dec 2001

Role Of Wetlands And Endogenous Factors On Incubation Behavior Of Nesting Spectacled Eiders On The Yukon-Kuskokwim Delta, Alaska, William Todd O'Connell

Biological Sciences

Patterns of nest attendance in ducks vary with endogenous and environmental factors. We examined variation in nest attendance of spectacled eiders on the Yukon-Kuskokwim Delta, Alaska, during 1997-1998. We also examined spatial and temporal variation in wetland characteristics and potential foods available to nesting spectacled eiders. Time spent foraging was greater when spectacled eiders traveled farther to feed, and nest attendance was lower when food was more abundant, suggesting that females made tradeoffs between foraging and energetic requirements of nesting in response to food abundance and wetland conditions. Wetlands were dynamic, and food abundance varied with pond depth and total …

Calving Ground Habitat Selection: Teshekpuk Lake And Western Arctic Caribou Herds, Rebecca A. Kelleyhouse Dec 2001

Calving Ground Habitat Selection: Teshekpuk Lake And Western Arctic Caribou Herds, Rebecca A. Kelleyhouse

Biological Sciences

Barren-ground caribou (Rangifer tarandus granti) exhibit relative fidelity to calving grounds each spring. The Western Arctic Herd (WAH) and Teshekpuk Lake Herd (TLH) calve separately on Alaska's north slope, each selective of the dominant vegetation type. The WAH consumed mostly sedges, though the TLH diet varied. Despite differing snow conditions between the calving grounds, both herds were selective of the lowest snow cover class. Rugged terrain was avoided by both herds. While the TLH selected a high rate of increase in biomass, the WAH selected high biomass at calving and at peak lactation. Climate trends (1985-2001) were variable. There was …

Trace Mineral Reserves For Reproduction And Development In Muskoxen, Emmajean Pearl Rombach Dec 2001

Trace Mineral Reserves For Reproduction And Development In Muskoxen, Emmajean Pearl Rombach

Biological Sciences

In muskoxen (Ovibos moschatus), trace minerals required for reproduction and development are unknown. I described use of copper in pregnant muskoxen and concurrent accumulation of copper in fetuses. Utilization of copper was examined in neonates during early development and importance of milk as a source of copper was assessed. Additionally, I examined the effect of maternal copper supplementation during gestation on copper reserves acquired in-utero, and during lactation on mineral status of milk. During gestation, the fetus must acquire reserves of copper adequate to support early neonatal development because milk is a poor source of copper. The transition from milk …

Longitudinal Variation In Muscle Protein Expression And Contraction Kinetics Of Largemouth Bass Axial Muscle, Tierney M. Thys, Jason M. Blank, David J. Coughlin, Fred Schachat Dec 2001

Longitudinal Variation In Muscle Protein Expression And Contraction Kinetics Of Largemouth Bass Axial Muscle, Tierney M. Thys, Jason M. Blank, David J. Coughlin, Fred Schachat

Biological Sciences

The present study investigates muscle protein expression in largemouth bass Micropterus salmoides through intra- and intermyomeric comparisons of white muscle. Using denaturing SDS-polyacrylamide gel electrophoresis, muscle protein expression in the arm and cone regions of sequential myomeres was compared for three bass. Low percentage (4.75 %) polyacrylamide-SDS gels and cyanogen bromide (CNBr) peptide mapping revealed no obvious intramyomeric differences between the myosin heavy chains of the arm and cone regions. Electrophoresis of myofibrils and muscle homogenates on higher percentage gels also failed to demonstrate any significant differences between arm and cone regions in either the myosin light chains or any …

Physics Conference Proceedings And The Electronic Environment—An Investigation Of New Dissemination Patterns., Michael Fosmire Dec 2001

Physics Conference Proceedings And The Electronic Environment—An Investigation Of New Dissemination Patterns., Michael Fosmire

Libraries Research Publications

The electronic publication of articles from physics conference proceedings on the arXive preprint server and on dedicated conference web sites is investigated. Several subdisciplines within physics were sampled. Except for high-energy theory conferences, and to a lesser extent astrophysics, there is almost no publication of proceedings articles on the preprint server. Only one conference out of all those sampled had a web site with conference presentations on it. That web site contained audio files of the presentations and images of the overheads used and thus had much different content than the published proceedings.

Evaluation Of Chitosan As A Cell Scaffolding Material For Cartilage Tissue Engineering, Dana Lynn Nettles Dec 2001

Evaluation Of Chitosan As A Cell Scaffolding Material For Cartilage Tissue Engineering, Dana Lynn Nettles

Theses and Dissertations

Current articular cartilage tissue engineering endeavors, using synthetic polymers as scaffolds, have been somewhat successful. However, the use of these materials has not yielded a satisfactory, functional replacement for articular cartilage. Therefore, this project focuses on an alternative to these materials, chitosan, which is a naturally occurring biopolymer. The first project objective was to fabricate and analyze bulk, porous chitosan scaffolds, based on total porosity, average pore diameter, mechanical integrity, and degradation susceptibility. Secondly, scaffolds were evaluated in terms of their ability to support neochondrogenesis, including assessments of cell attachment and viability, cell morphology, and the biosynthesis of proteoglycan and …

Evaluation Of An Attached Growth Organic Media Bioreactor For Swine Waste Treatment And Odor Abatement, Allison Paige Kirkpatrick

Theses and Dissertations

The objective of this study was to determine if an organic media attached growth bioreactor could effectively be used as a means of odor control for swine waste. The pilot-scale attached growth bioreactor system was evaluated against a standard pit recharge system, which served as the control. Performance was based on water quality testing, odor assessments by a human sensory panel, and air phase measurements of ammonia and hydrogen sulfide. The affect of aeration on the system was also evaluated, along with various types of organic media (kenaf, hardwood mulch, and corncobs). Overall, the bioreactor systems were effective in reducing …
