Cofeeding Intra- And Interspecific Transmission Of An Emerging Insect-Borne Rickettsial Pathogen, Lisa D. Brown, Rebecca C. Christofferson, Kaikhushroo H. Banajee, Fabio Del Piero, Lane D. Foil, Kevin R. Macaluso

Faculty Publications

© 2015 The Authors. Molecular Ecology Published by John Wiley & Sons Ltd. Cat fleas (Ctenocephalides felis) are known as the primary vector and reservoir of Rickettsia felis, the causative agent of flea-borne spotted fever; however, field surveys regularly report molecular detection of this infectious agent from other blood-feeding arthropods. The presence of R. felis in additional arthropods may be the result of chance consumption of an infectious bloodmeal, but isolation of viable rickettsiae circulating in the blood of suspected vertebrate reservoirs has not been demonstrated. Successful transmission of pathogens between actively blood-feeding arthropods in the absence of a disseminated …

Combined Next-Generation Sequencing And Morphology Reveal Fine-Scale Speciation In Crocodile Skinks (Squamata: Scincidae: Tribolonotus), Eric N. Rittmeyer, Christopher C. Austin Jan 2015

Combined Next-Generation Sequencing And Morphology Reveal Fine-Scale Speciation In Crocodile Skinks (Squamata: Scincidae: Tribolonotus), Eric N. Rittmeyer, Christopher C. Austin

Faculty Publications

© 2014 John Wiley & Sons Ltd. Next-generation sequencing has vast potential to revolutionize the fields of phylogenetics and population genetics through its ability to collect genomic scale data sets of thousands of orthologous loci. Despite this potential, other types of data (e.g. morphology, ecology) remain important, particularly for studies endeavouring to delimit species. Here, we integrate next-generation sequencing with morphology to examine divergence between populations of Tribolonotus pseudoponceleti on the islands of Buka and Bougainville in the Solomon Archipelago. We used the Ion Torrent PGM to collect over 648 Mbp of sequence data for 12 samples, representing 1526 loci …

Comparative Gut Microbiota Of 59 Neotropical Bird Species, Sarah M. Hird, César Sánchez, Bryan C. Carstens, Robb T. Brumfield

Faculty Publications

© 2015 Hird, Sánchez, Carstens and Brumfield. The gut microbiota of vertebrates are essential to host health. Most non-model vertebrates, however, lack even a basic description of natural gut microbiota biodiversity. Here, we sampled 116 intestines from 59 Neotropical bird species and used the V6 region of the 16S rRNA molecule as a microbial fingerprint (average coverage per bird ~80,000 reads). A core microbiota of Proteobacteria, Firmicutes, Bacteroidetes, and Actinobacteria was identified, as well as several gut-associated genera. We tested 18 categorical variables associated with each bird for significant correlation to the gut microbiota; host taxonomic categories were most frequently …

Similarity Thresholds Used In Dna Sequence Assembly Fromshort Reads Can Reduce The Comparability Of Population Histories Across Species, Michael G. Harvey, Caroline Duffie Judy, Glenn F. Seeholzer, James M. Maley, Gary R. Graves, Robb T. Brumfield Jan 2015

Similarity Thresholds Used In Dna Sequence Assembly Fromshort Reads Can Reduce The Comparability Of Population Histories Across Species, Michael G. Harvey, Caroline Duffie Judy, Glenn F. Seeholzer, James M. Maley, Gary R. Graves, Robb T. Brumfield

Faculty Publications

© 2015 Harvey et al. Comparing inferences among datasets generated using short read sequencing may provide insight into the concerted impacts of divergence, gene flow and selection across organisms, but comparisons are complicated by biases introduced during dataset assembly. Sequence similarity thresholds allow the de novo assembly of short reads into clusters of alleles representing different loci, but the resulting datasets are sensitive to both the similarity threshold used and to the variation naturally present in the organism under study. Thresholds that require high sequence similarity among reads for assembly (stringent thresholds) as well as highly variable species may result …

An Investigation Of Bag3 Knockdown And Its Effects On The Cytotoxicity Of Laromustine, Colin Sheehan Jan 2015

An Investigation Of Bag3 Knockdown And Its Effects On The Cytotoxicity Of Laromustine, Colin Sheehan

Honors Theses

Laromustine is a sulfonylhydrazine anticancer prodrug whose main cytotoxic arises from its ability to interfere with DNA replication of dividing cells. Multiple studies have suggested that Laromustine induces a form of cell death known as apoptosis. In a previous study investigating the mechanism of apoptosis, bcl2-associated athanogene 3 (BAG3) demonstrated significant upregulation in the presence of Laromustine. Given its anticancer ability, we selected BAG3 as a target for further investigation. BAG3 knockdown through transient shRNA transfections was performed in U138 glioblastoma multiforme cells and verified using qRT-PCR analysis. Finally, cell death assays were used to assess Laromustine’s cytotoxic effect on …

Acl Injuries In Female Athletes: Are Prevention Programs The Answer?, Brooke Chandor Jan 2015

Acl Injuries In Female Athletes: Are Prevention Programs The Answer?, Brooke Chandor

Honors Theses

Around 400,000 people tear their anterior cruciate ligaments (ACLs) every year in the United States. The majority of these injuries occur during athletics, and most commonly to females. Their neuromuscular abilities, anatomies, and hormones put female athletes at a much higher risk of ACL injury than male athletes. The current gold standard of treatment, ACL reconstruction, is an imperfect technique at best. It leaves patients with much higher risk of both ACL reinjury and early onset of osteoarthritis. Prevention programs, aimed at reducing the neuromuscular risk factors in female athletes, have proved to effectively reduce the number of noncontact ACL …

Mathematical Modeling Of Emiliania Huxleyi And A Host-Specific Virus, Julia Middleton Jan 2015

Mathematical Modeling Of Emiliania Huxleyi And A Host-Specific Virus, Julia Middleton

Honors Theses

The world’s oceans provide the basis for life on the planet. One microscopic algae, the coccolithophores, and Emiliania huxleyi in particular, is a major source of carbon drawdown in the context of the global carbon cycle and account for a significant amount of the primary production in oceanic ecosystems. We know that the oceans are packed with marine viruses and they have an important role in the rise and fall of plankton populations but current mathematical models do not accurately account for virus-host interactions when predicting plankton blooms. Therefore I am using model optimization and comparison techniques to evaluate current …

The Growing Crisis In Maine: Neonatal Abstinence Syndrome, Olivia Avidan Jan 2015

The Growing Crisis In Maine: Neonatal Abstinence Syndrome, Olivia Avidan

Honors Theses

Neonatal Abstinence Syndrome (NAS) is a Maine epidemic. In addition to having medical repercussions, NAS is intrinsically linked to social, political and economic factors. NAS is a conglomeration of symptoms, short-term and long-term, that affect a child that has been exposed to opioids in utero. These factors that impact NAS are interdependent. The past decade is characterized by a dramatic rise in NAS cases in Maine. This paper explores the social, political and economic landscape surrounding NAS in an effort to describe fully the syndrome’s effect on both individuals and the community as a whole.

A Constellation Of Caring: The Dynamic And Fluctuating Nature Of Pediatric Cancer Care, Anne Friedrich Jan 2015

A Constellation Of Caring: The Dynamic And Fluctuating Nature Of Pediatric Cancer Care, Anne Friedrich

Honors Theses

This honors thesis explores the fluctuating and dynamic nature of pediatric cancer care. I discuss the ways in which pediatric medical providers make meaningful interactions both for themselves and for their patients by enacting a caring liminality that allows them to fight disease while also creating a more personal, relational, and social moment of care. Providers care and work in shifting landscapes of care, what I call carescapes. The carescapes of the built environment, of value, and of physical movement all make the provider’s liminality visible. Ultimately, I argue that care is a way of being in the world, …

Assessing The Carbon Impacts Of Colby College’S Biomass Plant, Alice Hotopp Jan 2015

Assessing The Carbon Impacts Of Colby College’S Biomass Plant, Alice Hotopp

Honors Theses

Biomass energy plants are considered to be carbon neutral systems under some definitions. However, this concept of carbon neutrality needs to be rethought in order to understand the true carbon impact of biomass plants upon global climate change. A biomass plant’s wood source, the extent to which the biomass plant emits carbon dioxide, and the timescale over which the biomass plant emits carbon should all be taken into account. In this study, I consider the Colby College biomass plant’s role in carbon cycling. Colby’s Physical Plant Department provided me with information on how much carbon (tons of woodchips) is used …

N-Acetylcysteine Increased Rice Yield, Mohd Nozulaidi, Md Sarwar Jahan, Mohd Khairi, Mohammad Moneruzzaman Khandaker, Mat Nashriyah, Yusop Mohd Khanif

Turkish Journal of Agriculture and Forestry

N-acetylcysteine (NAC) biosynthesized reduced glutathione (GSH), which maintains redox homeostasis in plants under normal and stressful conditions. To justify the effects of NAC on rice production, we measured yield parameters, chlorophyll (Chl) content, minimum Chl fluorescence (Fo), maximum Chl fluorescence (Fm), quantum yield (Fv/Fm), net photosynthesis rate (Pn), photosynthetically active radiation (PAR), and relative water content (RWC). Four treatments, N1G0 (nitrogen (N) with no NAC), N1G1 (N with NAC), N0G0 (no N and no NAC), and N0G1 (no N but with NAC), were arranged in a completely randomized design with five replications. Nitrogen significantly increased yield and yield parameters of …

Auxin-Mediated Growth Of Rice In Cadmium-Contaminated Soil, Hussna Farooq, Hafiz Naeem Asghar, Muhammad Yahya Khan, Muhammad Saleem, Zahir Ahmad Zahir Jan 2015

Auxin-Mediated Growth Of Rice In Cadmium-Contaminated Soil, Hussna Farooq, Hafiz Naeem Asghar, Muhammad Yahya Khan, Muhammad Saleem, Zahir Ahmad Zahir

Turkish Journal of Agriculture and Forestry

Pollution from heavy metals is a global problem that is very dangerous to the environment. Among the heavy metals, cadmium is receiving more and more attention because it is one of the most ecotoxic, making it very harmful for biological activity in soil, biodiversity, plant metabolism, and human and animal health. Phytohormones, produced by plants, control or regulate germination, growth, metabolism, or other physiological activities, and they can alleviate the toxic effects of heavy metals on plant growth. Auxin is the most abundant natural growth hormone, controlling apical dominance, tropism, elongation of shoots, and initiation of roots in plants. However, …

A Simpler Route To Building Photochromic Cinnamaldehyde Semicarbazones, Byron R. Ebbert Jan 2015

A Simpler Route To Building Photochromic Cinnamaldehyde Semicarbazones, Byron R. Ebbert

Masters Theses

Photochromic semicarbazones are an interesting group of compounds that show potential in a broad range of applications, including as a more environmentally friendly replacement for photochromic metal complex compounds. Previous work has shown the feasibility to synthesize photochromic cinnamaldehyde semicarbazones (CSCs) from a benzaldehyde and a protected acetaldehyde Wittig reagent. A new, quicker, and cheaper approach to constructing these CSCs from crotonaldehyde was explored in this research. A three reaction sequence would convert crotonaldehyde to a CSC; first, an allylic bromination of the semicarbazone with N-bromosuccinimide (NBS); second, an Arbuzov reaction to prepare the semicarbazone phosphonate; and finally a condensation …

Creative Writing Pedagogy: The Autobiographical Narrative In Hybrid Projects As A Means To Explore Intersectionality, Tana G. Young Jan 2015

Creative Writing Pedagogy: The Autobiographical Narrative In Hybrid Projects As A Means To Explore Intersectionality, Tana G. Young

Masters Theses

My thesis addresses the role of creative writing methods in fostering close observation, attention to detail, critical thinking and a keener awareness of intersectionalities in writing classrooms across disciplines, but most especially the humanities and social sciences. I contend that the "real work" of the academy is critical thinking. Further, using creative writing, specifically autobiographical narrative in FYC, anticipates multimodal projects and digital storytelling, all of which fosters creative and critical thinking.

Derivatization And Separation Of Natural Estrogens (Estrone, 17Β-Estradiol, And Estriol) Using Gas Chromatography With Flame Ionization Detection (Gc-Fid), Dena L. Guptill Jan 2015

Derivatization And Separation Of Natural Estrogens (Estrone, 17Β-Estradiol, And Estriol) Using Gas Chromatography With Flame Ionization Detection (Gc-Fid), Dena L. Guptill

Masters Theses

A major cause of concern for estrogens found in the environment is that even at very low concentrations (10-100 ng/L) they can have a negative effect on aquatic ecosystems by disrupting endocrine systems. Due to the increasing importance of monitoring the levels of estrogens in the environment, a detection method was developed to identify and quantify three natural estrogens (estrone, 17β-estradiol and estriol) using gas chromatography with flame ionization detection (GC-FID). In addition, the efficacy of two derivatizing agents, N,O-bis(trimethylsilyl) acetamide (BSTA) and N,O-bis(trimethylsilyl)trifluoroacetamide (BSTFA), was evaluated. The GC detector (FID) was most responsive with E3, followed by E1 and …
