Background
Human scabies is a debilitating skin disease caused by the “itch mite” Sarcoptes scabiei. Ordinary scabies is commonly treated with topical creams such as permethrin, while crusted scabies is treated with topical creams in combination with oral ivermectin. Recent reports of acaricide tolerance in scabies endemic communities in Northern Australia have prompted efforts to better understand resistance mechanisms and to identify potential new acaricides. In this study, we screened three essential oils and four pure compounds based on eugenol for acaricidal properties.
Methodology/Principal Findings
Contact bioassays were performed using live permethrin-sensitive S. scabiei var suis mites harvested from …A Toolkit For Rapid Gene Mapping In The Nematode Caenorhabditis Briggsae, Daniel C.

Background
The nematode C. briggsae serves as a useful model organism for comparative analysis of developmental and behavioral processes. The amenability of C. briggsae to genetic manipulations and the availability of its genome sequence have prompted researchers to study evolutionary changes in gene function and signaling pathways. These studies rely on the availability of forward genetic tools such as mutants and mapping markers.
Results
We have computationally identified more than 30,000 polymorphisms (SNPs and indels) in C. briggsae strains AF16 and HK104. These include 1,363 SNPs that change restriction enzyme recognition sites (snip-SNPs) and 638 indels that range between 7 …

Isoform-Specific Regulation And Localization Of The Coxsackie And Adenovirus Receptor In Human Airway Epithelia, Katherine J.D.A. Excoffon, Nicholas D. Gansemer, Matthew E. Mobily, Philip H. Karp, Kalpaj R. Parekh, Joseph Zabner

Adenovirus is an important respiratory pathogen. Adenovirus fiber from most serotypes co-opts the Coxsackie-Adenovirus Receptor (CAR) to bind and enter cells. However, CAR is a cell adhesion molecule localized on the basolateral membrane of polarized epithelia. Separation from the lumen of the airways by tight junctions renders airway epithelia resistant to inhaled adenovirus infection. Although a role for CAR in viral spread and egress has been established, the mechanism of initial respiratory infection remains controversial. CAR exists in several protein isoforms including two transmembrane isoforms that differ only at the carboxy-terminus (CAREx7 and CAREx8). We found low-level …

Freshwater planarians, Plathelminthes, have been an intriguing model animal of regeneration studies for more than 100 years. Their robust regenerative ability is one of asexual reproductive capacity, in which complete animals develop from tiny body fragments within a week. Pluripotent adult somatic stem cells, called neoblasts, assure this regenerative ability. Neoblasts give rise to not only all types of somatic cells, but also germline cells. During the last decade, several experimental techniques for the analysis of planarian neoblasts at the molecular level, such as in situ hybridization, RNAi and fluorescence activated cell sorting, have been established. Moreover, information about genes …
Constitutive And Jasmonate-Inducible Defenses In Phloem Of Two North American And Two Asian Ash Species Grown In A Common Garden, Qin Wang
Browse all Theses and Dissertations
Emerald Ash Borer (EAB) is more damaging to North American ashes than Asian ashes. Variation in the resistance of ash species to feeding by larvae of EAB may be related to variation in levels of chemical defenses in the phloem. I compared constitutive and methyl jasmonate (MeJA)-inducible levels of several chemical defenses in the phloem of young Manchurian, Chinese, white, and green ashes. Manchurian ash is known to be highly resistant to attack by EAB in the field, while white and green ashes are both susceptible. The hypotheses of this experiment were that: (1) Manchurian (Fraxinus mandshurica) and Chinese ash …
Impacts Of A Herbivorous Fish, Campostoma Anomalum (Central Stoneroller), On Nitrogen Fixation By Benthic Algae, Chad Robert Schwinnen

Herbivorous fish negatively impact algal biomass and promote the growth of cyanobacteria. In nutrient poor conditions that sustain high levels of productivity nitrogen fixing cyanobacteria can supply up to 28% of the available nitrogen (Higgins et al. 2001) We investigated the role of grazing fish in sustaining high levels of productivity in nutrient poor conditions. We used the grazing minnow, Campostoma anomalum, and the acetylene reduction technique in a controlled environment to analyze rates of nitrogen fixation and primary production by the periphyton. Fish grazing reduced algal biomass and promoted the growth of cyanobacteria but had no impact on overall …

The importance of ecological interactions in the origin and maintenance of species diversity remains unclear. The current study assesses how ecological interactions shape the process of evolutionary diversification using a gall midge-host plant system in Ohio involving the gall midge, Asteromyia carbonifera (Diptera: Cecidomyiidae), and its goldenrod (Solidago) host-plants. A. carbonifera form four morphologically distinctive gall morphs and differ genetically. I studied phenology, host-plant specialization, and parasitism at three field sites in Southwestern Ohio. Phenology was assessed for twelve weeks while host-plant distribution and pressure from parasitoids were measured by monthly plot and rearing gall collections. Relative gall frequencies and …

The neotropics harbor an enormous diversity of tachinid flies, yet the fauna remains poorly known. The tribe Blondeliini is particularly diverse in this region and desperately needs taxonomic attention. Here, I present a revision of the neotropical genus Erythromelana Townsend including the redescription of three previously described species and the description of 11 new species. Two species previously assigned into this genus, are resurrected as distinct genera. Erythromelana species are widely distributed from southern Mexico to northern Argentina, with the Andes being a hotspot of diversity. Erythromelana are specialized on geometrids in the genus Eois, which mainly feed on plants …

The prevalence of allergenic diseases and sensitization to stored product mites is increasing worldwide. Stored product mites are prevalent in homes, foods, and some work environments. Stored product mites need to be further studied so we can characterize their inflammatory properties to understand their role in skin disease, and provide proper treatment to patients with mite allergies. The purpose of the study was to show the role of stored product mites in modulating the inflammatory and immune response to human dermal endothelial cells in the skin. The epidermis serves as the first line of defense between the body and the …

Habitat and forage selection by deer can cause local extinction of plant species. In my research, I asked: 1) How do deer population growth rates in urban parks change through time? 2) Are culling rates and deer densities correlated? 3) Are browse rates on Trillium spp. and deer densities correlated? I used FLIR deer census data from Davis Aviation and culling data from Five Rivers MetroParks (Montgomery County, Ohio). I found that deer population growth rates generally declined from 2003 to 2008. The number of deer culled was positively correlated to the deer densities. The browse rates of Trillium spp. …
