Temperature Affects Adhesion Of The Acorn Barnacle (Balanus Amphitrite), Laurel A. Johnston

Master's Theses

Biofouling is the accumulation of sessile marine organisms, such as algae, tube worms and barnacles on man-made substrata and has negative economic and ecological implications. Ship hulls are readily fouled, which significantly increases drag while decreasing ship fuel efficiency when moving through water. Fouled hulls have also become important vectors of invasive species. These problems are minimized when hulls are painted with a toxic anti-fouling or non-toxic foul-release coating. Due to recent restrictions of anti-fouling paint use, research and development of non-toxic alternatives has increased.

Novel hull coating efficiency is often quantified by the critical removal stress value of barnacles …

Developing A Source Water Protection Plan For Boron In The San Luis Obispo County Water Supply, Jenny Macartney

Master's Theses

The goal of this project is to design a feasible way to develop a protection plan for boron in the surface waters and groundwater of San Luis Obispo County. Boron is a micronutrient needed by all plants and animals but the threshold for toxicity in plants is narrow. As the need for water increases and the production of wastewater and irrigation water infiltrates the soil and waters of the County, an understanding of background soil and water concentrations, as well as anthropogenically produced sources of boron must be quantified and mapped so that intelligent planning decisions can be made.

Don't Tease Me, I'M Working: Examining Humor In A Midwestern Organization Using Ethnography Of Communication, Ajay K. Ojha, Taimmy L. Holmes

The Qualitative Report

Within organizations, the communicative phenomenon of humor is commonplace. Humorous talk is just as important and frequent to regular discourse that takes place between organizational members. In this inquiry we examine humor as a particular way of communicating between members of a small Midwestern United States organization. Specifically, we examine how three functions of humor (i.e., joking, sarcasm, and teasing) are used amongst members during normal business hours (8:00 a.m. - 5:00 p.m.). Using ethnography of communication, we conduct both fieldwork and interviews discovering that this organization exemplifies humor as a socially constructed phenomenon to complete the typical workday.

Parity-Induced Decrease In Systemic Growth Hormone Alters Mammary Gland Signaling: A Potential Role In Pregnancy Protection From Breast Cancer, Robert K. Dearth, David A. Delgado, Jill K. Hiney, Thushangi Pathiraja, Steffi Oesterreich, Dan Medina, W. Les Dees, Adrian V. Lee

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

Early full-term pregnancy is an effective natural protection against breast cancer in both humans and experimental rodents. The protective effect of an early pregnancy is in part linked to changes in circulating hormones that are involved in both normal breast development and breast cancer. For example, a reduction in circulating growth hormone (GH) has been shown to protect rats from carcinogen-induced mammary tumors. We examined the ability of a full-term pregnancy to alter the endocrine GH/IGF-I axis and how this change affected normal mammary gland function in two commonly used rat models (Sprague-Dawley and Wistar-Furth). Circulating GH and IGF-I were …

Cardioprotection By Regular Ethanol Consumption: Potential Mechanisms And Clinical Application., Masami Miyamae, Kazuhiro Kaneda, Naochika Domae, Vincent M. Figueredo, M.D.

Division of Cardiology Faculty Papers

Epidemiological studies demonstrate that excessive drinking is associated with hypertension, cerebral bleeding and loss of cardiac contractility. Conversely, studies have shown that mortality rates for people who regularly drink ethanol in moderation are lower than in abstainers, primarily due to decreased fatal ischemic heart disease. Further, moderate ethanol consumers have lower rates of myocardial infarction compared with abstainers. These beneficial cardiac effects may be due to pleiotropic effects of ethanol on lipids, platelets, and fibrinolytic activity. During the past decade, studies conducted in several animal models have revealed that light to moderate regular ethanol consumption renders hearts more tolerant to …

Molecular Diagnosis Of A Previously Unreported Predator-Prey Association In Coffee: Karnyothrips Flavipes Jones (Thysanoptera: Phlaeothripidae) Predation On The Coffee Berry Borer, Juliana Jaramillo, Eric G. Chapman, Fernando E. Vega, James D. Harwood

All Peer-Reviewed Publications

The coffee berry borer, Hypothenemus hampei, is the most important pest of coffee throughout the world, causing losses estimated at US 500 million/year. The thrips Karnyothrips flavipes was observed for the first time feeding on immature stages of H. hampei in April 2008 from samples collected in the Kisii area of Western Kenya. Since the trophic interactions between H. hampei and K. flavipes are carried out entirely within the coffee berry, and because thrips feed by liquid ingestion, we used molecular gut-content analysis to confirm the potential role of K. flavipes as a predator of H. hampei in an organic …

Sequence Analysis Of Leuconostoc Mesenteroides Bacteriophage Φ1-A4 Isolated From An Industrial Vegetable Fermentation, Jean Lu, Eric Altermann, Frederick Breidt, Sergei Kozyavkin

Faculty Articles

Vegetable fermentations rely on the proper succession of a variety of lactic acid bacteria (LAB) including Leuconostoc mesenteroides. L. mesenteroides initiates the fermentation, producing lactic and acetic acids, CO2, and many flavor compounds. As the fermentation proceeds, L. mesenteroides dies off and other LAB complete the fermentation. Phage infecting L. mesenteroides may significantly influence the die-off of L. mesenteroides. However, no L. mesenteroides phages have been previously sequenced and genetically characterized. Knowledge of more phage genome sequences may provide new insights into phage genomics and phage-host interactions. We have determined the complete genome sequence of L. mesenteroides phage (phi)1-A4, which …

Sailing Stormy Seas: The Illness Experience Of Persons With Parkinson's Disease, Melinda Stanley-Hermanns, Joan Engebretson

The Qualitative Report

Parkinson's disease is a chronic, progressive disorder with no known cause or promising cure. While substantial information is known about the pathophysiology, little is known about the illness experience of living with the disease. A qualitative study using an ethnographic approach was conducted to provide a rich understanding of the illness experience. The illness experience was apprehended through field work in two support groups and the personal accounts of 14 participants with Parkinson's disease. The metaphor, "Sailing the Sea in The Eye of the Storm," is the overarching theme and was chosen to conceptualize the voyage of persons living with …

Dispersion Of Single-Walled Carbon Nanotubes In Organic Solvents, Qiaohuan Cheng

Doctoral

This thesis contains a systematic study of the dispersion of pristine HiPco Single Walled Carbon Nanotubes (SWNTs) in a series of organic solvents. A double beamed UV-Vis-NIR absorption spectrometer coupled with an integrating sphere was employed to demonstrate the dispersibility of SWNTs in different solvents. Raman Spectroscopy and Atomic Force Microscopy (AFM) were used to confirm the debundling and exfoliation of SWNTs aggregates. An investigation of the solubility of SWNTs in four chlorinated aromatic solvents demonstrated that the similarity in structure between solvent molecules and nanotube sidewall is not a dominant factor to obtain stable SWNT solutions. A comparative study …

Top-K Aggregation Queries Over Large Networks, Xifeng Yan, Bin He, Feida Zhu, Jiawei Han

Research Collection School Of Computing and Information Systems

Searching and mining large graphs today is critical to a variety of application domains, ranging from personalized recommendation in social networks, to searches for functional associations in biological pathways. In these domains, there is a need to perform aggregation operations on large-scale networks. Unfortunately the existing implementation of aggregation operations on relational databases does not guarantee superior performance in network space, especially when it involves edge traversals and joins of gigantic tables. In this paper, we investigate the neighborhood aggregation queries: Find nodes that have top-k highest aggregate values over their h-hop neighbors. While these basic queries are common in …

Medially: A Provenance-Aware Remote Health Monitoring Middleware, Atanu Roy Chowdhury, Ben Falchuk, Archan Misra

Research Collection School Of Computing and Information Systems

This paper presents MediAlly, a middleware for supporting energy-efficient, long-term remote health monitoring. Data is collected using physiological sensors and transported back to the middleware using a smart phone. The key to MediAlly's energy efficient operations lies in the adoption of an Activity Triggered Deep Monitoring (ATDM) paradigm, where data collection episodes are triggered only when the subject is determined to possess a specified context. MediAlly supports the on-demand collection of contextual provenance using a novel low-overhead provenance collection sub-system. The behaviour of this sub-system is configured using an application-defined context composition graph. The resulting provenance stream provides valuable insight …

Yeast Cell Adhesion Molecules Have Functional Amyloid-Forming Sequences, Caleen B. Ramsook, Cho Tan, Melissa C. Garcia, Raymond Fung, Gregory Soybelman, Ryan Henry, Anna Litewka, Shanique O’Meally, Henry N. Otoo, Roy A. Khalaf, Anne M. Dranginis, Nand K. Gaur, Stephen A. Klotz, Jason M. Rauceo, Chong K. Jue, Peter N. Lipke

Publications and Research

The occurrence of highly conserved amyloid-forming sequences in Candida albicans Als proteins (H. N. Otoo et al., Eukaryot. Cell 7:776–782, 2008) led us to search for similar sequences in other adhesins from C. albicans and Saccharomyces cerevisiae. The beta-aggregation predictor TANGO found highly beta-aggregation-prone sequences in almost all yeast adhesins. These sequences had an unusual amino acid composition: 77% of their residues were beta-aggregation aliphatic amino acids Ile, Thr, and Val, which is more than 4-fold greater than their prevalence in the S. cerevisiae proteome. High beta-aggregation potential peptides from S. cerevisiae Flo1p and C. albicans Eap1p rapidly formed insoluble …

Structure And Function Of Glycosylated Tandem Repeats From Candida Albicans Als Adhesins, Aaron T. Frank, Caleen B. Ramsook, Henry N. Otoo, Cho Tan, Gregory Soybelman, Jason M. Rauceo, Nand K. Gaur, Stephen A. Klotz, Peter N. Lipke

Publications and Research

Tandem repeat (TR) regions are common in yeast adhesins, but their structures are unknown, and their activities are poorly understood. TR regions in Candida albicans Als proteins are conserved glycosylated 36-residue sequences with cell-cell aggregation activity (J. M. Rauceo, R. De Armond, H. Otoo, P. C. Kahn, S. A. Klotz, N. K. Gaur, and P. N. Lipke, Eukaryot. Cell 5:1664–1673, 2006). Ab initio modeling with either Rosetta or LINUS generated consistent structures of three-stranded antiparallel beta-sheet domains, whereas randomly shuffled sequences with the same composition generated various structures with consistently higher energies. O- and N-glycosylation patterns showed that each TR …

Platelet Alpha- And Beta- Secretase Activities Are Not Significantly Affected By Dementia Or Mild Cognitive Impairment In Swedish Patients., Paul Gorham, Natalie Bark, Ingemar Bjorkhem, Steve Meaney, Milita Crisby

Articles

The processing of the Amyloid Precursor Protein (APP) is a critical event in the formation of amyloid plaques which are composed of the 4kDa amyloid β-peptide (Aβ). Processing of APP occurs through a non-amyloidogenic pathway, mediated by initial α-secretase cleavage or through an amyloidogenic pathway via sequential cleavage by β- and γ- secretase enzymes, which produces Aβ peptides. Currently, the diagnosis of probable or possible Alzheimer's disease (AD) is primarily based on neuropsychological and neuroradiological assessment. Recent reports indicate that platelet β- secretase activity is moderately increased in patients with AD and mild cognitive impairment (MCI). To our knowledge platelet …

Partitioning Paternity: The German Approach To A Disjuncture Between Genetic And Legal Paternity With Implications For American Courts, Shelly Ann Kamei

San Diego International Law Journal

This paper will address the strengths and weaknesses of the German approach as well as the potential use of this approach by American states, with particular emphasis given to the conflict between the right to know one’s origins and a child’s right to care and support. Part II discusses the challenge of defining legal paternity in an age of genetic certainty. It will first give a brief explanation of how courts have used functional–social and genetic considerations in defining legal paternity. It will then evaluate the legal implications of this approach on the rights of the father, mother, and child. …

An Investigation Into Factors Influencing The Sensory Properties Of Selected Irish Grown Organic And Conventional Vegetables, Clare Gilsenan

Doctoral

Research studies conducted on organic produce have given conflicting results whether they have superior sensory qualities when compared to conventionally cultivated produce. The development and implementation of a reliable testing system is therefore required. In this study Irish grown organic and conventional carrots (cv. Nairobi), potatoes (cv. Orla) and tomatoes (cv. Amoroso) were selected for physicochemical (size, colour, dry matter, texture, sugars, o Brix & pH), volatile emissions and sensory analysis (trained and consumer panels). All vegetables were tested in both a raw and cooked state. Few significant differences were apparent between the organic and conventional vegetables for the physicochemical …

A Five‐Gene Signature As A Potential Predictor Of Metastasis And Survival In Colorectal Cancer, J Hao, J Chen, H Sui, X Si‐Ma, Et Al

School of Biomedical Sciences

To understand the molecular mechanisms of metastasis and prognosis of colorectal cancer (CRC), we isolated single cell-derived progenies (SCPs) from SW480 cells in vitro and compared their metastatic potential in an orthotopic CRC tumour model in vivo. Two groups of SCPs with the capability of high and low metastasis, respectively, were obtained. By analysing the gene expression profiles of high (SCP51), low (SCP58) metastatic SCPs, and their parental cell line (SW480/EGFP), we demonstrated that 143 genes were differentially expressed either between SCP51 and SCP58 or between SCP58 and SW480/EGFP. Gene-annotation enrichment analysis of DAVID revealed 80 genes in the top …
