Modeling Of The Dorsal Gradient Across Species Reveals Interaction Between Embryo Morphology And Toll Signaling Pathway During Evolution, Priscilla Ambrosi, Juan Sebastian Chahda, Hannah R. Koslen, Hillel J. Chiel, Claudia Mieko Mizutani

Faculty Scholarship

Morphogenetic gradients are essential to allocate cell fates in embryos of varying sizes within and across closely related species. We previously showed that the maternal NF-κB/Dorsal (Dl) gradient has acquired different shapes in Drosophila species, which result in unequally scaled germ layers along the dorso-ventral axis and the repositioning of the neuroectodermal borders. Here we combined experimentation and mathematical modeling to investigate which factors might have contributed to the fast evolutionary changes of this gradient. To this end, we modified a previously developed model that employs differential equations of the main biochemical interactions of the Toll (Tl) signaling pathway, which …

Comparative Assessment Of Diverse Strategies For Malaria Vector Population Control Based On Measured Rates At Which Mosquitoes Utilize Targeted Resource Subsets, Gerry F. Killeen, Samson Sifael Kiware, Aklilu Seyoum, John E. Gimnig, George Corliss, Jennifer Stevenson, Christopher J. Drakeley, Nakul Chitnis

Electrical and Computer Engineering Faculty Research and Publications

Background

Eliminating malaria requires vector control interventions that dramatically reduce adult mosquito population densities and survival rates. Indoor applications of insecticidal nets and sprays are effective against an important minority of mosquito species that rely heavily upon human blood and habitations for survival. However, complementary approaches are needed to tackle a broader diversity of less human-specialized vectors by killing them at other resource targets.

Methods

Impacts of strategies that target insecticides to humans or animals can be rationalized in terms of biological coverage of blood resources, quantified as proportional coverage of all blood resources mosquito vectors utilize. Here, this concept …

Electrospinning Of Ceria And Nickel Oxide Nanofibers, Jyothi Swaroop Reddy Yerasi

Theses

Electrospinning uses an electrical charge to draw very fine fibers from a liquid. It has very high potential for industrial processing. Electrospinning is cost effective, repeatable and it can produce long, continuous nanofibers. Polymers such as polyalcohol, polyamides, and PLLA can be easily electrospun. The increase in demand for clean energy combined with the research work in progress and the potential advantages of electrospun electrodes over conventionally fabricated SOFCs makes electrospinning a strong candidate. In this thesis, ceramic nanofibers (ceria and nickel oxide) that can potentially be used in SOFCs are fabricated.

A three-phase approach is implemented in the fabrication …

A Rhetorical Analysis Of The Rethinking Aids Website, Jennifer Dettmann

Journal of Undergraduate Research at Minnesota State University, Mankato

A group of scientists known as the Group for Scientific Reappraisal of the HIV-AIDS hypothesis created a web site title, Rethinking AIDS. The group behind the web site argues that AIDS is not a sexually transmitted disease. They even question the existence of the virus entity. My analysis is driven by the critical question: Does the web site construct a reality that affectively alters our perception of HIV-AIDS? In order to answer this question, Goodnight and Poulakos 1981 article, Conspiracy rhetoric: from pragmatism to fantasy to public discourse (Western Journal of Speech), will be utilized.

Dining With John And Catharine Butler Before The Close Of The Eighteenth Century, Eva Macdonald, Suzanne Needs-Howarth

Northeast Historical Archaeology

The partial excavation of the homestead of Colonel John Butler in the town of Niagara-on-the-Lake has afforded the opportunity to explore the daily activities of one Loyalist family after the establishment of the British colony of Upper Canada in the 1780s. In particular, the large collection of zooarchaeological material (over 14,5000 specimens) can provide information about the availability of wild animal species, as well as the types of domestic animals that the Butlers kept on their farm. Butchering marks provide further insight into the types of meat cuts used in cooking meals for the family and guests. These are compared …

The Power Of Choice: Reflections Of Economic Ability, Status, And Ethnicity In The Foodways Of A Free African American Family In Northwestern New Jersey, Megan E. Springate, Amy Raes

Northeast Historical Archaeology

The choices people make concerning food involve decisions well beyond biological sustenance. Food procurement and consumption, as well as the way in which a dish is served, are choices that are embedded with both overt and less obvious implications of social aspirations and validations (McKee 1999; Reitz, Ruff, and Zierden 2006). Food and the means by which it is prepared and consumed embody and communicate cultural traditions, as well as factors such as social identity, ethnicity, status, class, and consumer choice. In this article, we examine the faunal remains, tablewares, and food-preparation vessels recovered during excavations within a free African …

Health Risks Caused By Wireless Technologies, Durreeshahwar Zafarahmed, Qurrat-Ul-Ain Zafarahmed

Journal of Undergraduate Research at Minnesota State University, Mankato

There are many health issues related to the use of cellular phones, wireless local area networks, and other devices that emit electromagnetic radiation (EMR). Some of these systems have become a part of our daily lives and many of us are in direct or indirect contact for extended period of times with these devices. However, the general public is unaware of the health risks associated with the use of these devices. Our research covers studies done by individuals as well as organizations on the harmful effects on the health of people from these devices and their claims. We also present …

Chromosome Counts For Packera Paupercula Variety Gypsophila, Chad Larson

Journal of Undergraduate Research at Minnesota State University, Mankato

New plant species develop when diploid plants (having two sets of chromosomes) spontaneously double their chromosomes and the resulting tetraploids (having four sets of chromosomes) are no longer able to back cross to diploid members of the population. The North American plant species Packera paupercula (balsam-leafed ragwort), is widespread and morphologically diverse. An isolated group of populations from the chalky soils of west-central Alabama was recently named Packera paupercula variety gypsophila (the chalk-loving balsam ragwort). The variety’s large diameter pollen grains suggest it may be tetraploid. This project attempts the first chromosome count for the variety by examining cells undergoing …

The Effects Of Room Color On Stress Perception: Red Versus Green Environments, Teresa M. Kutchma

Journal of Undergraduate Research at Minnesota State University, Mankato

The purpose of the study was to investigate the effects of red versus green room colors on individual perception of stress. Room color was found through previous studies to have specific effects on psychomotor activity and emotional states. Correlations were found between red room color and emotional and physical stimulation, while green was associated with inhibitory effects. Additionally, Goldstein’s theory of color perception showed that red has stimulating effects on human behavior. Subjects consisted of 15 female and 15 male college freshmen at Minnesota State University, Mankato. An experimental booth was used for red, green and white room conditions. Subjects …

Nisin Resistance Of Bacillus Cerus: Preparation Of Nisin, Peter Weber

Journal of Undergraduate Research at Minnesota State University, Mankato

Nisin is a peptide that is made by the bacterium Lactococcus lactis. Nisin is a small molecule that kills gram positive bacteria by binding to their membrane and by disrupting the proton motive force. When food is processed it is heated to kill bacteria, but some bacteria still survive. Adding nisin to the food provides a second barrier for the growth of the bacteria. Purified nisin has become quite expensive in the current marketplace. Therefore this study is directed at producing nisin and purifying it. L. lactis was grown in five different media (BHI, BHI + 1% glucose, BHI + …

The Innate Immune Response In Eisenia Fetida To Microbial Challenges, Aaron Schindler

Journal of Undergraduate Research at Minnesota State University, Mankato

The common earthworm, Eisenia fetida, exhibits a rudimentary immune system. The earthworm needs cellular and chemical responses against a constant microbial exposure from its natural environment. Some cellular and chemical responses are found in the coelomic fluid and have been shown to demonstrate anti-microbial characteristics. This project uses microscopy and modified staining techniques to differentiate and categorize the cellular components found in the coelomic fluid. Following a microbial challenge by Klebsiella pneumoniae, an inflammatory response was initiated. Six groups of earthworms were injected with 0.05 ml of 1.0 x 106 cfu /ml K. pneumoniae on day one and tested over …

An Economic Analysis Of Small-Scale Biodiesel Production: Implementation Of Ethyl Ester Production In A Job Shop Setting, Scott Haase, Benjamin Craig

Journal of Undergraduate Research at Minnesota State University, Mankato

Biodiesel is becoming a demanded consumer automotive alternative fuel used in diesel vehicles today. An emerging trend is toward small-scale biodiesel production performed by the final consumer. A limited source of commercially available production systems exists and has resulted in many systems being designed and built by the user. Preliminary research conducted by the authors has shown biodiesel to be the least-cost alternative to petroleum diesel after as few as 8 months of system use. This study examines the economic viability of building and producing biodiesel using a small-scale production system versus buying consumer petroleum diesel. During production, measurements were …

Comparison Of Sequence Alignment Algorithms, Tejas Gandhi

Journal of Undergraduate Research at Minnesota State University, Mankato

The fact that biological sequences can be represented as strings belonging to a finite alphabet (A, C, G, and T for DNA) plays an important role in connecting biology to computer science. String representation allows researchers to apply various string comparison techniques available in computer science. As a result, various applications have been developed that facilitate the task of sequence alignment. The problem of finding sequence alignments consists of finding the best match between two biological sequences. A best match can infer an evolutionary relationship and functional similarity. However, there is a lack of research on how reliable and efficient …

Distinguishing Observed Inattentive Behaviors In The College Classroom As They Correlate To Brain Wave Activity Utilizing A Wireless Electroencephalograph, Christopher J. Aura, Matthew R. Stanton

Journal of Undergraduate Research at Minnesota State University, Mankato

A significant amount of research has been devoted to the behavioral correlates of inattention in children (A.P.A., 2000; Arnold, 2000; Gordon & Barkley, 1998). It is proposed by the authors that college students, in their several years of experience, are much more capable of masking these trademark behaviors. When a child loses interest they will begin to openly look around the room, shift in their seat, or chat with their neighbors (Sandberg, Rutter & Taylor, 1978; Arnold, 2000). College students however, are proposed to candidly fidget, shift in their seat, or even maintain eye contact with their instructor while “daydreaming”. …

Histological Evaluation Of The Cryo-Destruction Of The Zona Glomerulosa (Outermost Layer) Of The Adrenal Cortex, Huda Ahmed, Jonida Pone

Journal of Undergraduate Research at Minnesota State University, Mankato

The outer portion, or cortex, of the adrenal gland produces three hormones, two of which are highly critical to normal function of the body. The cortex itself is divided into three layers, each responsible for a certain hormone synthesis. The outermost layer (zona glomerulosa) produces aldosterone, a hormone involved in the regulation of body sodium, blood volume, and blood pressure. The middle layer produces co rticosterone, a hormone that is active in a variety of biological functions, and necessary for life. Due to its effects on blood volume, aldosterone has been implicated in the development of hypertension, or high blood …

Childhood Stress: A Qualitative Analysis Of The Intergenerational Circumstances Of Child Hunger, Mariana Chilton, Molly Knowles

University of Kentucky Center for Poverty Research Discussion Paper Series

Adverse Childhood Experiences (ACEs), including abuse, neglect, and household instability, affect lifelong health and economic potential. While relationships between household food insecurity and caregiver’s childhood exposure to abuse and neglect are underexplored, preliminary evidence indicates that caregivers reporting very low food security report traumatic events in their childhoods that lead to poor physical and mental health. Building on this evidence, this study investigates how adverse childhood experiences are associated with the intergenerational transmission of household food insecurity.

The Jak2 Small Molecule Inhibitor, G6, Reduces The Tumorigenic Potential Of T98g Glioblastoma Cells In Vitro And In Vivo, Rebekah Baskin, Sung O. Park, György M. Keserű, Kirpal S. Bisht, Heather L. Wamsley, Peter P. Sayeski

Chemistry Faculty Publications

Glioblastoma multiforme (GBM) is the most common and the most aggressive form of primary brain tumor. Jak2 is a non-receptor tyrosine kinase that is involved in proliferative signaling through its association with various cell surface receptors. Hyperactive Jak2 signaling has been implicated in numerous hematological disorders as well as in various solid tumors including GBM. Our lab has developed a Jak2 small molecule inhibitor known as G6. It exhibits potent efficacy in vitro and in several in vivo models of Jak2-mediated hematological disease. Here, we hypothesized that G6 would inhibit the pathogenic growth of GBM cells expressing hyperactive Jak2. To …
