Distinctly organized domains of receptors, ion channels, transporters, signaling molecules, cell adhesion molecules, and contractile proteins are crucial to cardiac function. Interactions between adaptor proteins such as ankyrins and cytoskeletal proteins such as obscurin play a pivotal role in organizing these functional domains in cardiomyocytes. Therefore, dysfunction of both ankyrin as well as obscurin lead to a host of cardiovascular diseases such as arrhythmias and cardiomyopathies. Alternative splicing of ankyrin yields numerous isoforms that interact with obscurin at various sub-cellular domains. And while some of these obscurin-ankyrin complexes have been studied, many others have not been characterized. Further, previous studies ...


Differential Vulnerability To Window Collision Mortality Among Migratory Songbird Species, Olivia M. Colling 2019 The University of Western Ontario

Differential Vulnerability To Window Collision Mortality Among Migratory Songbird Species, Olivia M. Colling

Electronic Thesis and Dissertation Repository

Millions of birds die annually in North America by colliding with windows. I investigated differential vulnerability to window collision among migratory songbird species using long-term citizen science datasets from two bird banding stations and the fatal light awareness program. I used negative binomial regressions to model species-specific catch ratios, a mixed-effects negative binomial regression to model trophic guild-specific catch ratios and mixed-effects logistic regressions to model the odds of catching different age classes. Species-specific vulnerability varied significantly. Blue-headed Vireos, Yellow-rumped Warblers and Ruby-crowned Kinglets were least vulnerable, while Ovenbirds, Common Yellowthroats, Fox Sparrows and Bay-breasted Warblers were most vulnerable. Foraging ...


Does Thermotolerance In Daphnia Depend On The Mitochondrial Function?, Rajib Hasan 2019 East Tennessee State University

Does Thermotolerance In Daphnia Depend On The Mitochondrial Function?, Rajib Hasan

Electronic Theses and Dissertations

Thermotolerance limit in aquatic organism is set by the ability to sustain aerobic scope to sudden temperature shifts. This study tested the genetic and plastic differences in thermotolerance of Daphnia that can be explained by the differences in the ability to retain mitochondrial integrity at high temperatures. Five genotypes with different biogeographic origins were acclimated to 18C and 25C. We developed a rhodamine 123 in-vivo assay to measure mitochondrial membrane potential and observed higher fluorescent in heat damaged tissues as the disruption of the mitochondrial membrane potential. Significant effects on temperature tolerance were observed with CCCP ...


Assessment Of Culverts And Bridges As Roosting Habitat For Perimyotis Subflavus (Tri-Colored Bat) And Disease Transmission Corridors For Pseudogymnoascus Destructans, Kelly Lutsch 2019 Kennesaw State University

Assessment Of Culverts And Bridges As Roosting Habitat For Perimyotis Subflavus (Tri-Colored Bat) And Disease Transmission Corridors For Pseudogymnoascus Destructans, Kelly Lutsch

Master of Science in Integrative Biology Theses

Pseudogymnoascus destructans is an emerging fungal pathogen causing precipitous declines in North American bats due to the development of white-nose syndrome. Since 2006, 34 U.S. states and 7 Canadian provinces have confirmed the presence of P. destructans. Due to the rapid spread of P. destructans across the eastern United States, habitat characterization and disease monitoring has become vital to conserving remnant populations. Bats have been observed in multiple states using non-traditional habitat, such as interstate culverts, for roosting. To investigate their use of anthropogenic structures in coastal Georgia, an area where P. destructans has yet-to-be detected, comprehensive bridge and ...

Using Instream Stationary Antennas To Monitor The Movements Of Warm Water Fishes In A Reach Of Stream Bisected By A Culvert, William Commins

Master of Science in Integrative Biology Theses

In this study I investigated the differences in the non-migratory movement patterns of six fish species in a 280m reach of stream bisected by a culvert (impeded), and a 300m reach of stream with no movement barriers (unimpeded). This study took place between July 1, 2018 and November 14, 2018 in Raccoon Creek, Paulding County, Georgia. I used 12mm passive integrated transponder tags and four instream stationary antennas to monitor the movements 429 fishes. The antennas redetected 262 of the 429 individuals (61.1%), and 48% of fishes were redetected more than 10 times. The proportion of tagged individuals detected ...


The Developmental And Behavioral Effects Of Δ9-Tetrahydrocannabinol On A Spastic Mutant, Victoria Mendiola 2019 Kennesaw State University

The Developmental And Behavioral Effects Of Δ9-Tetrahydrocannabinol On A Spastic Mutant, Victoria Mendiola

Master of Science in Integrative Biology Theses

Hyperekplexia is a neurological disorder affecting infants and can be characterized by excessive startle reactions in response to unexpected stimuli. This disease can be modeled in zebrafish in the bandoneon (beo) mutant, where the glrbbmutation results in glycine receptor (GLYR) loss of function glycine receptors and ultimately, improper inhibitory signaling. Though hyperekplexia is a glycinergic-based signaling disorder, disease symptoms are often alleviated with GABA-agonistic benzodiazepines. Exogenous cannabinoids also modulate GABAergic signaling, and THC, one of the natural compounds that prompted the discovery of the endocannabinoid system mimics the effects of endogenous cannabinoids at endocannabinoid and non-cannabinoid sites in the ...


Delivering Signal-Altering Bacterial Effector Proteins To Mammalian Cells Using Cell-Penetrating Peptide Technology, Robert Dickson 2019 Kennesaw State University

Delivering Signal-Altering Bacterial Effector Proteins To Mammalian Cells Using Cell-Penetrating Peptide Technology, Robert Dickson

Master of Science in Integrative Biology Theses

A major role of the mitogen activated protein kinase (MAPK) pathway in eukaryotes is to activate the bacterial pathogen defense response upon the detection of bacterial products in the environment. This defensive signaling results in the induction of inflammation, the transcription of antimicrobial peptides, the modulation of the cell cycle and cell survival. Some Gram-negative bacteria have evolved needle-like structures called Type III Secretion Systems (T3SS) that secrete signal-altering molecules into the host cell to interrupt signaling pathways that would otherwise lead to the elimination of the bacterial infection. These signal-altering molecules are known as bacterial effector proteins (BEPs). Bacterial ...

Structure-Based Design Of Hepatitis C Virus Vaccines That Elicit Neutralizing Antibody Responses To A Conserved Epitope, Brian G. Pierce, Elisabeth N. Boucher, Kurt H. Piepenbrink, Ejemel Monir, Chelsea A. Rapp, William D. Thomas Jr., Eric J. Sundberg, Zhiping Weng, Yan Wang

Kurt Piepenbrink

Despite recent advances in therapeutic options, hepatitis C virus (HCV) remains a severe global disease burden, and a vaccine can substantially reduce its incidence. Due to its extremely high sequence variability, HCV can readily escape the immune response; thus, an effective vaccine must target conserved, functionally important epitopes. Using the structure of a broadly neutralizing antibody in complex with a conserved linear epitope from the HCV E2 envelope glycoprotein (residues 412 to 423; epitope I), we performed structure-based design of immunogens to induce antibody responses to this epitope. This resulted in epitope-based immunogens based on a cyclic defensin protein, as ...

Loss Of Id4 Promotes Stemness In Prostate Cancer Cells, Dhanushka Hewabostanthirige 2019 Atlanta University Center

Loss Of Id4 Promotes Stemness In Prostate Cancer Cells, Dhanushka Hewabostanthirige

Electronic Theses & Dissertations Collection for Atlanta University & Clark Atlanta University

Inhibitor of differentiation 4 (ID4), a member of the helix-loop-helix family of transcriptional regulators has emerged as a tumor suppressor in prostate cancer (PCa). Recent studies have shown that Id4 is highly expressed in the normal prostate and decreases in prostate cancer due to epigenetic silencing. Id4 knockdown in androgen sensitive LNCaP cells has been shown to lead to castration resistant prostate cancer (CRPC) in vitro and in vivo. Id4-/- mice leads to underdeveloped prostate with PIN like lesions without the loss of Androgen Receptor (AR) expression. In this study we demonstrate that the loss of ID4 expression in PCa ...

Observations And Applications Of Husbandry Methodologies On A Backyard Poultry Farm In Dangriga, Belize, Bailey Carpenter

Animal Science Undergraduate Honors Theses

This study explores the husbandry methodologies on a backyard poultry farm in Dangriga, Belize, with the purpose of producing a set of guidelines for backyard poultry growers that have limited resources in similar regions. The majority of data collection occurred through survey questions approved by the IRB, necropsies approved by IACUC, and general observations. There has been a steady increase in poultry production in developing regions due to its positive effects on income and relative nutrition. However, due to a lack of accessible communication and education regarding effective and safe poultry production, these operators typically see poor productivity and/or ...

What Controls Tropical Reef Fish Populations: Recruitment Or Benthic Mortality? An Example In The Caribbean Reef Fish Haemulon Flavolineatum, M. J. Shulman, John C. Ogden 2019 Fairleigh Dickinson University

What Controls Tropical Reef Fish Populations: Recruitment Or Benthic Mortality? An Example In The Caribbean Reef Fish Haemulon Flavolineatum, M. J. Shulman, John C. Ogden

John Ogden

Recruitment from a planktonic larval stage has been proposed to be an important factor in limiting populations of marine organisms, particularly tropical reef fishes. We monitored recruitment and population densities of juvenile size classes In French grunt Haemulon flavolineatum (Haemulidae) from October 1978 through December 1980 In a portion of Tague Bay, St. Croix, U. S. Virgin Islands. Within our study area, 95 % of new recruits settled onto the sand and seagrass lagoon floor and within a few weeks migrated to nearby reefs; the remaining 5'10 settled directly onto reef structures. Mean annual recruitment rate was 1.8 recruits ...

The Caricomp Network Of Caribbean Marine Laboratories (1985–2007): History, Key Findings, And Lessons Learned, Jorge Cortes, Hazel A. Oxenford, Brigitta I. Van Tussenbroek, Eric Jordan-Dahlgren, Aldo Croquer, Carolina Bastidas, John C. Ogden

John Ogden

Caribbean Coastal Marine Productivity (CARICOMP) was a basin-wide cooperative, international network of marine laboratories established in 1985. Recognizing major trends of change in coastal ecosystems and the importance of the linkages among them, our goal was to monitor synoptically with standardized methods the physical environment and to document trends in measures of the structure and functioning of coral reefs, seagrasses and mangroves. Between 1985 and 1993, the CARICOMP Steering Committee established a data management center and wrote a methods manual. Marine laboratories joined the program by appointing a Site Director and signing an agreement specifying the cost sharing and responsibilities ...

Scale And Community Structure Of Coral Reef Fishes: A Long-Term Study Of A Large Artificial Reef, John C. Ogden, J. P. Ebersole

John Ogden

he fish community of a large artificial reef made In 1960 of 800 concrete blocks in a seagrass bed on the south coast of St. John, U.S. Virgin Islands, was studied by comparing a series of visual censuses (1975-1979) with each other and with a 1962 total-poison station collection (Randall, 1963). Discounting the presence of some cryptic species in the poison station that would not normally be seen in visual censuses (N = 10), as well as discounting seagrass-bed residents and roaming species only transient on the reef (N = 13), all of the censuses and the poison station (range 31-40 ...


Herbivory Effects On Thalassia Testudinum Leaf Growth And Nitrogen Content, J. C. Zieman, R. L. Iverson, John C. Ogden 2019 University of Virginia

Herbivory Effects On Thalassia Testudinum Leaf Growth And Nitrogen Content, J. C. Zieman, R. L. Iverson, John C. Ogden

John Ogden

The pattern of turtle grazing on Thalassia testudinum in St. Croix seagrass beds begins with the establishment of a grazing plot by initial removal of leaf blades, followed by repeated grazing of several centimeter-long leaf blades within a maintained grazing area. Plants within the grazed area exhibit increased specific growth rate as a consequence of increased light flux to unepiphytized leaf bases. Leaf width is reduced in the grazed area as a consequence of grazing stress. The leaf bases contain a higher proportion of nitrogen and a lower lignin content than the leaf tips, in addition to lacking epiphytes. Our ...
