Matrix Composition Affects The Spatial Ecology Of A Prairie Planthopper, Kyle J. Haynes, James T. Cronin

Faculty Publications

To date, there is a lack of well-controlled field experiments that disentangle the effects of the intervening matrix from other landscape variables (e.g., patch geography or quality) that might influence animal dispersal among patches. We performed a field experiment to investigate how the movement of a delphacid planthopper (Prokelisia crocea) among discrete patches of prairie cordgrass (Spartina pectinata) is affected by the composition of the matrix (mudflat, native nonhost grasses, and the introduced grass smooth brome [Bromus inermis]). Within each matrix type, marked planthoppers were released onto experimental cordgrass patches that were made identical in size, isolation, and host plant …

Two Rna Binding Proteins, Hen4 And Hua1 Act In The Processing Of Agamous Pre-Mrna In Arabidopsis Thaliana, Yulan Cheng, Naohiro Kato, Wenming Wang, Junjie Li, Xuemei Chen

Faculty Publications

AGAMOUS, a key player in floral morphogenesis, specifies reproductive organ identities and regulates the timely termination of stem cell fates in the floral meristem. Here, we report that strains carrying mutations in three genes, HUA1, HUA2, and HUA ENHANCER4 (HEN4), exhibit floral defects similar to those in agamous mutants: reproductive-to-perianth organ transformation and loss of floral determinacy. HEN4 codes for a K homology (KH) domain-containing, putative RNA binding protein that interacts with HUA1, a CCCH zinc finger RNA binding protein in the nucleus. We show that HUA1 binds AGAMOUS pre-mRNA in vitro and that HEN4, HUA1, and HUA2 act in …

Natural Bovine Lentiviral Type 1 Infection In Holstein Dairy Cattle. I. Clinical, Serological, And Pathological Observations, T. G. Snider, B. F. Jenny, P. G. Hoyt, K. S. Coats, K. F. Graves, C. R. Cooper, R. W. Storts, D. G. Luther

Faculty Publications

Clinical, serological, and pathological abnormalities observed in Holstein cows naturally infected with bovine lentivirus 1 bovine immunodeficiency virus (BIV) and other infections were progressive and most commonly associated with weight loss, lymphoid system deficiency, and behavioral changes. Clinical evidence of meningoencephalitis was dullness, stupor, and occasional head or nose pressing postures. The polymerase chain reactions associated the BIV provirus with the lesions in the central nervous system and lymphoid tissues. Multiple concurrent infections developed in retrovirally infected cows undergoing normal stresses associated with parturition and lactation. A major functional correlate of the lymphoreticular alterations was the development of multiple secondary …

Allelic Heterogeneity In Line-1 Retrotransposition Activity, Sheila M. Lutz, Bethaney J. Vincent, Haig H. Kazazian, Mark A. Batzer, John V. Moran

Faculty Publications

De novo LINE-1 (long interspersed element-1, or L1) retrotransposition events are responsible for ∼1/1,000 disease-causing mutations in humans. Previously, L1.2 was identified as the likely progenitor of a mutagenic insertion in the factor VIII gene in a patient with hemophilia A. It subsequently was shown to be one of a small number of active L1s in the human genome. Here, we demonstrate that L1.2 is present at an intermediate insertion allele frequency in worldwide human populations and that common alleles (L1.2A and L1.2B) exhibit an ∼16-fold difference in their ability to retrotranspose in cultured human HeLa cells. Chimera analysis revealed …

Haplotypes In The Dystrophin Dna Segment Point To A Mosaic Origin Of Modern Human Diversity, Ewa Ziȩtkiewicz, Vania Yotova, Dominik Gehl, Tina Wambach, Isabel Arrieta, Mark Batzer, David E.C. Cole, Peter Hechtman, Feige Kaplan, David Modiano, Jean Paul Moisan, Roman Michalski, Damian Labuda

Faculty Publications

Although Africa has played a central role in human evolutionary history, certain studies have suggested that not all contemporary human genetic diversity is of recent African origin. We investigated 35 simple polymorphic sites and one Tn microsatellite in an 8-kb segment of the dystrophin gene. We found 86 haplotypes in 1,343 chromosomes from around the world. Although a classical out-of-Africa topology was observed in trees based on the variant frequencies, the tree of haplotype sequences reveals three lineages accounting for present-day diversity. The proportion of new recombinants and the diversity of the Tn microsatellite were used to estimate the age …

Effect Of Horn Fly (Haematobia Irritans) Control On Growth And Reproduction Of Beef Heifers, S. M. Derouen, L. D. Foil, A. J. Mackay, D. E. Franke, D. W. Sanson, W. E. Wyatt

Faculty Publications

The influence of horn fly control with commercially available ear tags was studied on beef replacement heifers (n = 670) for growth and reproductive performance. The study was conducted at five sites in Louisiana over 3 yr. Heifers used were yearling replacement females that were exposed to fertile bulls during a limited spring breeding season that coincided with the horn fly season. In mid to late May of each year, heifers were randomly assigned to one of two horn fly treatments: untreated and treated for horn fly control. The trial continued each year until September or October at the end …

Synthesis Of Montiporynes A And B, Traci Jenelle Speed

Honors Theses

This thesis reports the first complete synthesis of monriporynes A and B. isomeric diacetylenes that bear α, β unsaturated ketone functionalities. Recently isolated from the stony coral Montipora sp. these compounds are reported to possess in vitro cytotoxic activity against several human solid tumor cells. We have synthesized both isomers in three simple steps. In the first step, l-iodononyne was prepared by reacting 1-nonyne with N-iodosuccinimide and a catalytic amount of silver nitrate. This iodoalkyne was then coupled with propargyl alcohol using copper iodide as the catalyst to give 2,4dodecadiynyl alcohol. Finally, the diacetylenic alcohol was subjected to the Swern …

Quantitative Analysis Of Diepoxybutane Damage Within The Chicken Β-Globin Domain, André M. Pilon

Honors Theses

In industrial polymer and synthetic rubber production facilities, workers are exposed to 1,3-butadiene. This compound is converted in vivo to 1,2,3,4-diepoxybutane (DEB) and has been linked to increased incidences of cancer in these individuals. Carcinogenesis has been attributed to formation of DEB induced DNA interstrand cross-links. Previous studies have demonstrated that DEB cross-links deoxyguanosine residues within 5'-GNC sequences in synthetic DNA, in restriction fragments, and in defined sequence nucleosomes. The current study utilized the polymerase chain reaction (PCR) to examine DEB damage frequencies within nuclear genes, found within "open" regions of chromatin, as compared to regions of unexpressed sequence that …

Double Stranded Dna-Binding Studies Of Potential Rhodium(Ll) Antitumor Complexes, Amity Elizabeth Burr

Honors Theses

In 1952, Dwyer and coworkers began testing a series of metal complexes for potential inhibition of cancer cell proliferation in animals.[l] The complexes tested were unsuitable for such studies due to their high toxicity. Therefore, no further work was done on the project. However, in 1965, Rosenberg and coworkers revisited the possibility of potential metal-based drugs. Serendipitously, they discovered that cis-diamminedichloroplatinum(lI) (cisplatin) inhibits cell division in E. coli.[2] Further studies of this and other platinum compounds revealed inhibition of tumor cell lines sarcoma 180 and leukemia LI2l0 in mice.[l] Cisplatin was approved by the Food and Drug Administration in 1970 …

Chlorobenzenes And Chloronitrobenzenes Interaction With Iron (O), Manuel Alejandro Serratos

Masters Theses

Degradation of chlorobenzene, dichlorobenzenes and chloronitrobenzenes (ClB, x-Cl2B and x-ClNO2B) was tested by trying to make them react with metallic iron, Fe (0), in water solvent.

The experiments consisted of optimizing the parameters of the reactions (like minimum mass of iron needed) and analytical detection conditions. Analytical techniques used were gas and liquid chromatography (GC and HPLC), mass spectrometry (MS) and UV-Vis spectroscopy.

No substances other than the initial ClB and x-Cl2B were detected in their tests with Fe (0) after shaking for periods of up to three days, although 10%weight average decreases in concentration were observed.

The ClNO2B isomers …

Individual Phonological Awareness Training For Speech/Language Impaired First Graders, Sarah Weaver

Masters Theses

The purpose of the present study is to determine the effects of individual phonological awareness and phonics training emphasizing auditory, motoric, and alphabetic properties of phonemes with 3 children who did not make substantial gains following classroom phonological awareness intervention. Subjects were enrolled in the first grade and exhibited speech and/or language impairments. The individual phonological awareness program contained 3 parts: (1) phonological awareness, (2) phoneme-grapheme correspondence, and (3) decoding and spelling and employed a single subject multiple probe baseline across behaviors design. Results indicated that individual treatment was successful for teaching phonological awareness, phoneme-grapheme correspondence, and decoding and spelling. …

Lacunae: Narrative "Lacks, Holes Or Gaps" In Faulkner's And Morrison's Novels, Phyllis Ann Karpus

Masters Theses

The moment a reader opens a book, turns to the opening lines and begins to read, a circular relationship immediately develops with the author and the text. An implied alliance is formed wherein the author, most often through a narrator, omniscient or otherwise, proposes to the reader that he/she accept a degree of responsibility for understanding the plot, theme, and the underlying meaning in the work.

Retrospectively the theory sounds simple and, with many authors, it is effective. William Faulkner and Toni Morrison, however, not only command but also demand, the reader's absolute attention in, and responsibility to, many of …

Nest-Site Selection In The Eastern Box Turtle, Terrapene Carolina Carolina, In A Population In Central Illinois, Beth Flitz

Masters Theses

Nest site selection in turtles might allow females to increase the survival of their offspring but little is known about the variables that influence that choice. I examined the microhabitat variables at nest sites of the eastern box turtle, Terrapene carolina carolina, at a Boy Scout camp in Shelby County, Illinois, to determine if females chose nest sites that differed from random sites within the camp. Nest sites differed from random sites in vegetation height and composition, percentage ground and canopy cover, and light intensity. All females placed their nests in open habitat within the camp or a pasture bordering …

Middle School Student Attitudes Towards Robotics, Science And Technology, J. Jill Rogers

Masters Theses

In 2000, the National Science Foundation (NSF) conducted a biennial study on the status of women and minorities in science and engineering. It was revealed that the numbers of women receiving bachelor's degrees in computer science are on the decline. This fact calls for innovative changes in the traditional science curriculum. Science instruction with the implementation of robotics could provide female students the needed motivation. Therefore, the examination of female middle school student attitudes towards robotic enhanced science instruction is needed. Descriptive research was conducted to assess middle school student attitudes towards robots, technology and science. Gender differences were studied. …

Anthropogenic-Induced Changes To Weather And Climate: An Overview, Robert Cataneo

Masters Theses

Human activities, since the beginning of the Industrial Revolution, have caused measurable and significant changes to local and regional weather and climate, as well as to global climate.

There is substantial evidence to show that anthropogenic influences have caused statistically significant changes to local and regional weather and climate, and have played a major role in the 0.6°C increase in global, low level temperature observed in the last 100 years. There is also an abundance of data that establishes a causal relationship between the 32% increase in atmospheric CO₂ concentration that has occurred since the beginning of the Industrial …

Motherlands Of The Mind: A Study Of The Women Characters Of Attia Hosain's Sunlight On A Broken Column And Salman Rushdie's Midnight's Children, Umme Sadat Nazmun Nahar Al-Wazedi

Masters Theses

In my thesis I examine the portrayal of women characters by two post-colonial Indian writers, Attia Hosain and Salman Rushdie, respectively in Sunlight on a Broken Column (1961) and Midnight's Children (1980). I show how Hosain's and Rushdie's ideas of identity, nation and nationality influence their depiction of these women characters.

In the section analyzing Sunlight on a Broken Column, I argue that there is a spatial veil separating the feudal world of "Ashiana" from the outside world with its political disturbances, the life of a woman as an individual from the life of a woman as a part …

The Relationship Between Thigh Muscle Size And 1rm Squat Strength Among Bodybuilders, Powerlifters, And Olympic Weightlifters, James Dinaso

Masters Theses

The purpose of this study was to determine if a significant difference exists in the relationship between measures of muscle size and strength among elite bodybuilders, powerlifters, and Olympic weightlifters. Fifteen male subjects between the ages of 16 and 48 years participated in the study. All three subject groups, Olympic weightlifters (OWL, n=5), powerlifters (PL, n=5), and bodybuilders (BB, n=5), were highly trained and currently involved in competition training. All test subjects were of similar body weight and weighed between 76-96 kilograms. Measures of body weight, body composition (bioelectrical impedence), shoulder width, thigh circumference (proximal, distal, and mid-thigh), and thigh …

Storying The Body : Women's Narratives Through The Lens Of Breast Cancer, Janet A. Griffin

Theses : Honours

What can women's narratives contribute to our understanding of breast cancer and to feminist theories of the body? This thesis explores the meanings women construct to make sense of embodied experiences of breast cancer, and the profound experience of breast loss. Rich contextual data was elicited from in depth, guided conversations with five premenopausal women who have undergone mastectomy. Adopting feminist methodology, biographic-narrative was used to place the body at the heart of inquiry. This thesis explores the personal and theoretical meanings of mastectomy, embedded in the larger story of how these five women experience their breasts, throughout their lives. …

The Effects Of Sleep On The Acquisition Of Skill, Peter G. Croy

Theses : Honours

The current research was designed to evaluate the effect of sleep on memory for the declarative and procedural knowledge components of a cognitive skill. In a training phase, 17 participants in a no-sleep control group practised 120 repetitions of a simple algebra equation at Sam and 22 participants in a sleep group practised the task at 8pm. Novel task inputs were introduced withh1 the same task structure in a transfer phase conducted 12 hours after training for each group. Overnight sleep conferred a 29% performance deficit on the transfer tusk compared to no-sleep controls. The results support the hypothesis that …

The Recovery Of Birds Through Farmland Revegetation In The Shire Of Goomalling, Western Australia, Rebecca Heath

Theses : Honours

The birds of grazed paddocks, early revegetation (less than three years in age), three to seven year old revegetation, older revegetation (greater than seven years in age) and remnant vegetation were surveyed over the course of one year to determine whether revegetation recovers avian biodiversity in agricultural landscapes. Habitat features that were useful to the birds, and those that were missing from revegetation, were identified in order to broaden the knowledge base of faunal use of farmland revegetation, and aid in the devising of successful revegetation strategies. Notable differences in the abundance and composition of birds were found between the …
