Characterization Of Anti-Tumor Immunity In Oyster Toadfish (Opsanus Tau), And The Effects Of 7,12 -Dimethylbenz(A)Anthracene On This Immune Response, Kenneth R. Seeley

Dissertations, Theses, and Masters Projects

Cell-mediated lysis of cultured tumor target cells by nonspecific cytotoxic cells (NCC) was examined in the oyster toadfish (Opsanus tau), an estuarine teleost. NCC activity was evaluated in cells taken from the head kidney, peripheral blood, spleen and peritoneal cavity. NCC activity was a property of plastic nonadherent cells which lacked phagocytic activity, indicating that in terms of their functional capacity, the cells which mediate nonspecific cytoxic immune responses in oyster toadfish do not appear to be monocytes or macrophages. However, light and electron microscopic examination of these cells revealed that morphologically, they resemble monocytes and macrophages. A new technique …

Effect Of Unilateral Temporal-Lobe Excision On Perception And Imagery Of Songs, Robert J. Zatorre, Andrea R. Halpern

Faculty Journal Articles

Auditory imagery for songs was studied in two groups of patients with left or right temporal-lobe excision for control of epilepsy, and a group of matched normal control subjects. Two tasks were used. In the perceptual task, subjects saw the text of a familiar song and simultaneously heard it sung. On each trial they judged if the second of two capitalized lyrics was higher or lower in pitch than the first. The imagery task was identical in all respects except that no song was presented, so that subjects had to generate an auditory image of the song. The results indicated …

The Effects Of Turf Compression On Plants Growth Regulator Efficacy, William Lyle Petersen

Masters Theses

A 150kg lawn roller was used in combination with various Plant Growth Regulators (PGR) (Embark & Event, Event & Oust, Embark & Oust, Escort & Oust, Telar & Oust, Event & Balan, Oust & Balan, and Balan) to evaluate its affects on the growth rate of rough turf at the Coles County Airport. The rolled plots were evaluated for height, reduction of seedheads, phytotoxicity, and weed control. Rolling was of no significance to treated or untreated turf. PGR combinations containing Oust were significantly better at reducing turf height than combinations lacking Oust. PGR combinations lacking Oust discolored turf significantly less …

The Effect Of Heart Rate And Rating Of Perceived Exertion While Exercising On The Stairmaster 4000pt With And Without Upper Body Support, Nicole Lamkin

Masters Theses

The purpose of this study was to determine if any differences exists between heart rate and rating of perceive exertion during exercise on the StairMaster 4000pt with and without upper body support. Thirteen female intercollegic athletes were examined during a 1.5 mile run and eight minutes of supported and eight minutes of non-supported StairMaster exercise. The subjects worked at a slow step rate for the first two minutes (4.9 METs) and the last six minutes each subject worked at 70% of their submaximal level achieved on the 1.5 mile run. Variables measured included HR and RPE. A one factor ANOVA …

Cardiovascular Responses Of Trained Cyclists To Different Pedaling Rates At A Constant Power Output On A Cycle Ergometer, David C. Immke

Masters Theses

Previous research has not resolved the issue as to which pedaling rate is the most efficient in terms of oxygen uptake (VO₂) for competitive cyclists. The purpose of this study was to determine the most efficient pedaling rate (30, 60, or 90 rpm) at steady state submaximal cycling (720 kpm/min) for trained cyclists. Eight healthy subjects (all male) were examined during steady state exercise for each of the three trials for which work rate was kept constant with varying pedal rate and resistance. Variables included oxygen uptake, cardiac output, heart rate, stroke volume, arterio-venous O₂ difference, respiratory …

The Effect Of Age On Recovery Of Heart Rate After Exercise, Shari A. Delisle

Masters Theses

The purpose of this study was to determine if heart rate recovery, following exercise, of active women aged between 50-63 years was significantly slower than the recovery of active women aged 23-24 years when both groups exercised at the same relative perceived intensity. Ten female subjects, five young and five older, were tested during a five minute bout of treadmill exercise while working at a rating of perceived exertion(RPE) of 14. Heart rate was measured prior to and during testing and into recovery using the Vantage Performance Monitor. The time, measured in seconds, it took for each subject to drop …

Effects Of Music And Sensory Deprivation On Ratings Of Perceived Exertion And Exercise Affect, James Chinery

Masters Theses

Music as an ergogenic aid is a novel concept, and one that has been sporadically researched. The purpose of this thesis was to study the effects of music and sensory deprivation on ratings of perceived exertion during exercise.

Eleven active males (i.e. they exercised at least 3 times a week), were tested in three different conditions (music, sensory deprivation, control). They exercised in each condition, at workloads corresponding to 50, 70 and 90% of their maximal oxygen consumption. The sessions and workloads within each session were randomized.

No significant differences were found for heart rate between conditions. Significantly lower perceived …

The Effects Of Nest-Box Visibility And Proximity On The Frequency Of Brood Parasitism In Wood Ducks, Roger W. Jansen

Masters Theses

I studied the effects of nest box visibility and clustering on the rate of intraspecific brood parasitism (IBP) in Wood Ducks (Aix sponsa) at Lake Shelbyville Fish and Wildlife Area in Moultrie County, IL from 2 March 1992 to 22 June 1992. Sixty-eight percent of the nest boxes sampled were used and 33% of the nests were destroyed by predators. Mean clutch sizes of unparasitized (x = 9.2) and parasitized (x = 15.2) nests were significantly different. The parasitism rate in Wood Duck nests was 54%. More visible boxes had a tendency to be parasitized at a higher rate than …

Phylogenetic Relationships Within The Batagur Complex (Testudines: Emydidae: Batagurinae), Jean M. Capler

Masters Theses

Relationships between 10 species of the batagurine genera Batagur, Callagur, Kachuga, Hardella, and Morenia are discussed based on a cladistic analysis of 35 morphological characters. Ocadia sinensis (Emydidae: Batagurinae) was used as the outgroup species. Four cladograms were produced with a length of 59.0 steps and a 0.75 consistency index. In contrast with previous studies, Hardella and Morenia do not appear as a monophyletic clade. Instead, Hardella is included with the remaining ingroup taxa (exclusive of Morenia) based on five synapomorphies. The present genus Kachuga was determined to be paraphyletic, having excluded the present genera Batagur and Callagur. The pangshura …

Growth And Survival Of Larval Fishes: The Role Of Zooplankton Abundance And Competition, Michael T. Welker

Masters Theses

Interactions among larval gizzard shad, bluegill and zooplankton prey were examined via a controlled mesocosm experiment and field sampling in Lake Shelbyville, Illinois. In the mesocosm experiment gizzard shad growth and survival were negatively correlated with shad density and positively correlated with macrozooplankton prey. Bluegill growth was also positively correlated with prey availability, but survival was uniformly high despite differences in zooplankton abundance and fish density. Declines in macrozooplankton and copepod biomass were related to fish density. In Lake Shelbyville limnetic overlap of larval gizzard shad and bluegill was limited to a three week period, with the interval of greatest …

An Investigation Of The Host Specificity Of The Brown-Headed Cowbird, Brian D. Peer

Masters Theses

We attempted to determine the factors associated with the lack of parasitism of the Common Grackle (Quiscalus quiscula) by the Brown-headed Cowbird (Molothrus ater). We investigated the breeding phenology of the two species, the responses of colonial- and noncolonial-nesting grackles to female cowbird models, the frequency of artificial egg rejection by grackles, incubation success of cowbird eggs transferred into grackle nests, and the survival rates of cowbirds cross-fostered into grackle nests.

By the time cowbirds began egg-laying at our study sites, 88.5 % of all grackle nests were beyond the point of successful parasitism. Grackles responded …

Biotic, Abiotic, And Behavioral Patterns Associated With The Nocturnal Movements Of Shrews, Patrick T. Sullivan

Masters Theses

Thirteen trails left by shrews coated with fluorescent powder were examined for microhabitat documentation. Thirteen data parameters were collected from each trail, two of which differed significantly between Blarina brevicauda and Sorex longirostris. The small soricid Sorex longirostris was captured in areas with higher grass content, and lower wooded content, than the larger Blarina brevicauda. The difference in microhabitat use may be a key mechanism in reducing competition between these two species.

Lichen Communities On White Oaks In East-Central Illinois, Michael R. Thon

Masters Theses

This study was conducted as a survey of epiphytic lichen communities occurring on white oak trees at Walnut Point State Park (Douglas Co.) and Fox Ridge State Park (Coles Co.). Using a system of cover classes to estimate lichen cover, quantitative data on the distribution and abundance of epiphytic lichens was obtained. These data were used to calculate summary statistics of each community including total cover, species richness, and Shannon diversity. A total of ten taxa representing six genera were found. The foliose lichen Physcia millegrana had the highest cover in the open canopy habitats while all other taxa had …

Corticolous Bryophytes Of East-Central Illinois, R. Korkut Canayakin

Masters Theses

Among the numerous factors that influence epiphytic corticolous bryophytes, inclination, "raintracks", aspect, and phorophyte seem to play important role.

In order to determine the effects of these factors, 203 forest trees located in five sites has been examined. The results were arranged in tables and charted.

Vegetation And Tree Survival In A Savanna Restoration Project, Vermilion County, Illinois, Mary Claire Hruska

Masters Theses

This study involved pre-burn and post-burn inventories of herbaceous and woody vegetation, a post-burn tree survival survey, the development and implementation of a management plan for the savanna restoration site and the development of general guidelines for savanna restoration. An herbarium collection was made, 242 species representing 64 families were found on the site.

There were several significant changes in the density and frequency of vegetation after the burn. The following herbaceous species increased significantly in frequency: Agalinis tenuifolia (Vahl.) Raf, Ambrosia artemisiifolia L., Carex spp., Cassia fasciculata Michx., Desmodium glabellum (Michx.) DC., Dichanthelium acuminatum (Sw.) Gould & Clark var. …

An Electromyographic Study Of Forward Vs Retrograde Stair Climbing On The Stairmaster 4000 Pt Machine, W. Lynette Rasmussen Thornburgh

Masters Theses

The purpose of this study was to investigate, through electromyography, whether forward or retrograde stair climbing on the StairMaster 4000 PT machine demonstrates a greater muscle contraction duration, differences in intensity of muscle contractions, or variation in initiation of muscle contractions. The muscles examined were the Rectus Femoris, Vastus Medialis, and Biceps Femoris. A gender difference was also evaluated.

Twenty-one subjects apparently healthy volunteered for this study. There were two groups of ten male subjects and eleven female subjects. Subjects were assigned to subgroups according to gender. The subgroups determined which position the subject was tested in first.

The descriptive …

Effects Of Predator Size And Female Receptivity On Courtship Behavior Of Captive-Bred Male Guppies, Given Harper, Kristin Braun

Given Harper

The effects of predator size and female receptivity on the courtship behavior of captivebred male guppies (Poecilia reticulata) were investigated. Male guppies exhibited riskreckless courtship behavior in that they did not decrease the amount of time spent performing visually conspicuous sigmoid displays and increase the frequency of attempted forced copulations when large predatory fish were present. Female receptivity (i.e., virgin or non-virgin females) also had no effect on male courtship behavior.

Ultrastructure Of The Coeloms Of Auricularia Larval (Holothuroidea Echinodermata): Evidence For The Presence Of An Axocoel, E. J. Balser, E. E. Ruppert, William Jaeckle

William Jaeckle

A hallmark feature of echinoderm larvae is the development of the left anterior coelom. This coelom, called the axohydrocoel, consists of the morphologically distinct, but undivided, left axocel and hydrocel. The axocoelic portion forms a duct that opens to the exterior via a pore on the dorsal surface of the animal. Holothuroid larvae are thought to lack an axocoel, but develop an anterior coelom, duct, and pore that are regarded as parts of the hydrocoel. New ultrastructural data, however, show that holothuroid auricularia larvae possess an axocel and hydrocel united together into an axohydrocoel. During development the anterior coelom consists …
