Reproductive Biology Of The Female Bottlenose Dolphin (Tursiops Truncatus), Holley Stone Muraco

Theses and Dissertations

The goal of this long-term study was to better understand the reproductive biology of the female bottlenose dolphin (Tursiops truncatus) and provide a hypothesis for how dolphins may communicate reproductive readiness to one another. Utilizing conditioned dolphins in aquaria, this dissertation examined several previously unknown aspects of dolphin reproduction, including ovarian follicular dynamics during the luteinizing hormone surge, urinary prolactin levels, estrus behavior, vaginal fluid arboriform arrangement, in-situ vaginal and cervical anatomy during estrus, reversed-phase high-performance liquid chromatography (RP-HPLC) of urine samples to identify proteins and peptides that may be used in chemical communication, and a review and anatomical analysis …

Territorial Defense Strategies In The Northern Cardinal (Cardinalis Cardinalis): Who Is The Bigger Threat?, Kaylee M. Gentry

Master's Theses

This thesis examines the use of defensive strategies in relation to territories year round in the northern cardinal (Cardinalis cardinalis). Responses to recorded neighbor song and stranger song playback from the middle of a focal male’s territory were measured. This allowed for an estimation of aggression in both the winter and spring seasons. Each focal male was subjected to both treatments (stranger song and neighbor song). Males were more responsive over-all to neighbor song playback, however in the winter months, persistence of response to neighbor song playback increased. It was also shown that southeastern United States cardinals show …

Racial Experience As An Alternative Operationalization Of Race, Jada Benn Torres, Gabriel A. Torres Colón

Human Biology Open Access Pre-Prints

The study of human variation is central to both social and biomedical sciences; however, despite agreeing that variation is integral to the human experience, social and biomedical scientists diverge in how variation is theorized and operationalized. Race becomes especially problematic because it is a cultural concept that contains implicit and explicit understandings of how collective bodies differ. In this paper, we propose an operationalization of race that is attentive to both racial experience and human biological diversity—placing them within the same ontological sphere. Furthermore, we argue that this approach can more effectively advance antiracist pedagogy and politics.

We argue that …

The Role Of The Scribble Protein Complex In The Regulation Of Dendrite Formation, Bingru Sun

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

During neuronal development, the neuronal cell polarizes to specify the structures of axons and dendrites. This polarized architecture regulates the input/output functions of the neuronal cell. In my thesis, I studied the molecular mechanisms of dendrite formation. My main hypothesis was that dendrite specification results from local elevation of the cGMP signal. Soluble guanylyl cyclase (sGC) is the major enzyme for the synthesis of cGMP in the embryonic brain. I study the molecular mechanism that activates sGC and leads to dendrite specification during neuronal polarization.Scribble is a scaffold protein, part of a polarity complex that establish apical-basal polarity in epithelial …

The Role Of Valproic Acid, A Histone Deacetylase Inhibitor, In Reducing Anxiety Levels In Rats: An Epigenetics Study, Juliet Buteme

Honors College Theses

Rats, like humans, show personality traits: they are born with different anxiety levels (i.e., high (HAn) or low anxiety (LAn) levels). In this study, we investigated (1) if treatment with valproic acid (VPA) can lower anxiety level in trait anxiety rats and (2) how VPA may interact with environment (e.g., enriched (EE), standard (SE) and isolated environments (IE)). VPA is a deacetylase inhibitor that increases Histone 3 acetylation, a known epigenetic mechanism that interacts with stress response proteins, and treats epilepsy and mood disorders. Since rats reared in IE exhibit heightened anxiety levels as compared to those in EE, we …

The Role Of Nitric Oxide In Skeletal Simulated Microgravity Response, Luan Tran

Master's Theses

Prolonged exposure to the space environment leads to bone loss. Using a ground-based model for microgravity (hind-limb unloading), it has been shown in rodents that proliferation and differentiation activity of osteoprogenitors are decreased with exposure to simulated microgravity (Kostenuik et al., 1997). Osteoblast mineralization activity has been shown to increase with nitric oxide supplementation (Afzal et al., 2004; Koyama et al., 2000). I hypothesized that the degenerative effects of microgravity exposure result from chronic changes in nitric oxide regulation in osteoprogenitors, and that supplementation with exogenous nitric oxide following exposure would ameliorate these changes. In 20 C57Bl/6 mice, hind-limb unloading …

Gardner-Webb Student Explores Opportunities In Field Of Science, Office Of University Communications

Gardner-Webb NewsCenter Archive

Wendy Harmon grew up with the mountains, rivers, lakes, and streams of western North Carolina at her back door. Some of her fondest memories are of outdoor exploratory excursions with her parents, Tommy and Darlene Harmon, where she literally first got her feet wet in ecology — the study of how organisms interact with their environments. Her mother was a Gardner-Webb graduate, but Harmon wanted to make her own decision about where to go to college.

Serum Proteins Enhance Dispersion Stability And Influence The Cytotoxicity And Dosimetry Of Zno Nanoparticles In Suspension And Adherent Cancer Cell Models, Catherine B. Anders, Jordan J. Chess, Denise G. Wingett, Alex Punnoose

Biomedical Research Institute Publications and Presentations

Agglomeration and sedimentation of nanoparticles (NPs) within biological solutions is a major limitation in their use in many downstream applications. It has been proposed that serum proteins associate with the NP surface to form a protein corona that limits agglomeration and sedimentation. Here, we investigate the effect of fetal bovine serum (FBS) proteins on the dispersion stability, dosimetry, and NP-induced cytotoxicity of cationic zinc oxide nanoparticles (nZnO) synthesized via forced hydrolysis with a core size of 10 nm. Two different in vitro cell culture models, suspension and adherent, were evaluated by comparing a phosphate buffered saline (PBS) nZnO dispersion (nZnO/PBS) …

A Phenomenological Study Of Public School Biology Teachers Who Believe In The Literal Genesis Account Of Creation, Eric Dougherty

Doctoral Dissertations and Projects

he purpose of this phenomenological study was to understand the experiences of Christian public high school biology teachers who believe in a literal, young earth account of creation as revealed in the book of Genesis. There is a gap in the literature regarding understanding the teaching experiences of Christians who believe in a strict interpretation of the biblical book of Genesis. This study was conducted by interviewing 11 Christian public school biology teachers from multiple states who met the criteria for being identified as young earth creationists. Data were also collected through a focus group and reflective vignettes. Data were …

How Science Teachers Balance Religion And Evolution In The Science Classroom: A Case Study Of Science Classes In A Florida Public School District, Pierre Willems

Doctoral Dissertations and Projects

The purpose of this case study was to research how science teachers balance both religion and evolution in the science classroom with as little controversy as possible. In this study I attempted to provide some insight on how teachers are currently teaching evolution in their science classes in light of the religious beliefs of the students as well as their own. The case study was conducted in a school district in Florida where I attempted to answer the following questions: (a) How do science teachers in the Florida School District (FSD) approach the religion–evolution issue in preparing students for a …

This includes databases of the sequences and structural information as well methods to access, search, visualize and retrieve the information. Bioinformatics concern the creation and maintenance of databases of biological information whereby researchers can both access existing information …

Science & Spaghetti Monsters: Understanding The Nature Of Scientific Knowledge & Research, Sarah O'Leary-Driscoll

Nature of Science

What is science?

When students are asked to define science, many of them define science as “a body of knowledge gained by performing experiments.”

A more appropriate definition, however, is that “Science is … a process of inquiry aimed at building a testable body of knowledge open to rejection or confirmation” (Shermer, 2005).

There are three important points that this definition makes:

Sequence Alignments

Now that you have learned how to do the four basic sequence alignments (Pairwise and Multiple for both nucleotide and protein sequences) select a gene/protein, it may be one that you've used before, and run each of these alignments.

Alignment Information, Sarah O'Leary-Driscoll

Sequence Alignments

Pairwise DNA alignment is frequently used to identify similar regions that will show how two sequences have functional or structural similarities. It can also be used to show how exons and introns change between different sequences and whether they have an effect on the final structure of the RNA after the DNA is processed within a cell.
