Electroencephalogram Coherence In Children With And Without Autism Spectrum Disorders: Decreased Interhemispheric Connectivity In Autism, Audrey Meyer Carson, Nicole M.G. Salowitz, Robert A. Scheidt, Bridget K. Dolan, Amy V. Van Hecke

Biomedical Engineering Faculty Research and Publications

Electroencephalogram coherence was measured in children with autism spectrum disorders (ASD) and control children at baseline and while watching videos of a familiar and unfamiliar person reading a story. Coherence was measured between the left and right hemispheres of the frontal, parietal, and temporal-parietal lobes (interhemispheric) and between the frontal and parietal lobes in each hemisphere (intrahemispheric). A data-reduction technique was employed to identify the frequency (alpha) that yielded significant differences in video conditions. Children with ASD displayed reduced coherence at the alpha frequency between the left and right temporal-parietal lobes in all conditions and reduced coherence at the alpha …

In Vivo Imaging Of Human Cone Photoreceptor Inner Segments, Drew Scoles, Yusufu N. Sulai, Christopher S. Langlo, Gerald A. Fishman, Christine A. Curcio, Joseph Carroll, Alfredo Dubra

Biomedical Engineering Faculty Research and Publications

Purpose.

An often overlooked prerequisite to cone photoreceptor gene therapy development is residual photoreceptor structure that can be rescued. While advances in adaptive optics (AO) retinal imaging have recently enabled direct visualization of individual cone and rod photoreceptors in the living human retina, these techniques largely detect strongly directionally-backscattered (waveguided) light from normal intact photoreceptors. This represents a major limitation in using existing AO imaging to quantify structure of remnant cones in degenerating retina.

Methods.

Photoreceptor inner segment structure was assessed with a novel AO scanning light ophthalmoscopy (AOSLO) differential phase technique, that we termed nonconfocal split-detector, in two healthy …

Impact Of Education On Grandparents’ Actions In Raising Grandchildren, Diana Doggett, Dory M. Marken, Diana J. Caldwell

Journal of Extension

Grandparents raising grandchildren represent a population of adults who confront complex interpersonal and environmental challenges. The intent of this case study was to gather and interpret evaluative data to better understand the impact of a 1-day community education program for grandparents who raise their grandchildren. Extension's philosophy of systematic program evaluation to improve supports for families and communities furnished the framework for the project. Elements felt to be essential for a well-designed, 1-day grandparent education program have been extracted from past evaluation cycles and offered here as recommendations.

Hydrilla Infestations In Florida Freshwater Bodies: How Results From A Management Needs Assessment Survey Helped Develop Suitable Information Delivery Platforms, Jennifer L. Gillett-Kaufman, Verena-Ulrike Lietze, Joan P. Bradshaw, Kenneth T. Gioeli

Journal of Extension

Hydrilla is an invasive aquatic plant that is expensive to control and exhibits increasing resistance to commonly used herbicides. Alternative control tactics for implementation in novel integrated management strategies are being investigated, but information needs to be delivered to stakeholders so new tactics can be adopted and used. Here, we report results from a low-cost, Web-based survey that assessed stakeholder access to hydrilla management information in Florida. We highlight the general benefits of needs assessment surveys for project development and exemplify how results from such surveys can be used by Extension professionals to tailor their information platforms to stakeholder-preferred outlets.

Modulation Of Hcn Channels In Lateral Septum By Nicotine, Sodikdjon A. Kodirov, Michael Wehrmeister, Luis V. Colom

Health & Biomedical Sciences Faculty Publications

The effects of addictive drugs most commonly occur via interactions with target receptors. The same is true of nicotine and its multiple receptors in a variety of cell types. However, there are also side effects for given substances that can dramatically change cellular, tissue, organ, and organism functions.

In this study, we present evidence that nicotine possesses such properties, and modulates neuronal excitability. We recorded whole-cell voltages and currents in neurons situated in the dorsal portion of the lateral septum in acute coronal brain slices of adult rats. Our experiments in the lateral septum revealed that nicotine directly affects HCN …

Identification Of Novel Small Rnas And Characterization Of The 6s Rna Of Coxiella Burnetii, Indu Warrier, Linda D. Hicks, James M. Battisti, Rahul Raghavan, Michael F. Minnick

Biology Faculty Publications and Presentations

Coxiella burnetii, an obligate intracellular bacterial pathogen that causes Q fever, undergoes a biphasic developmental cycle that alternates between a metabolically-active large cell variant (LCV) and a dormant small cell variant (SCV). As such, the bacterium undoubtedly employs complex modes of regulating its lifecycle, metabolism and pathogenesis. Small RNAs (sRNAs) have been shown to play important regulatory roles in controlling metabolism and virulence in several pathogenic bacteria. We hypothesize that sRNAs are involved in regulating growth and development of C. burnetii and its infection of host cells. To address the hypothesis and identify potential sRNAs, we subjected total RNA isolated …

Inhibition Of Food Intake By Pacap In The Hypothalamic Ventromedial Nuclei Is Mediated By Nmda Receptors, Jon M. Resch, Brian Maunze, Kailynn A. Phillips, Sujean Choi

Biomedical Sciences Faculty Research and Publications

Central injections of pituitary adenylate cyclase-activating polypeptide (PACAP) into the ventromedial nuclei (VMN) of the hypothalamus produce hypophagia that is dependent upon the PAC1 receptor; however, the signaling downstream of this receptor in the VMN is unknown. Though PACAP signaling has many targets, this neuropeptide has been shown to influence glutamate signaling in several brain regions through mechanisms involving NMDA receptor potentiation via activation of the Src family of protein tyrosine kinases. With this in mind, we examined the Src-NMDA receptor signaling pathway as a target for PACAP signaling in the VMN that may mediate its effects on feeding behavior. …

A Chant Of Dilation: Walt Whitman, Phrenology, And The Language Of The Mind, Anton Borst

Dissertations, Theses, and Capstone Projects

A Chant of Dilation analyzes Walt Whitman's poetic engagement with two very modern ideas: the materiality of the mind and the discursive nature of science. During the antebellum period these ideas found expression in the popular science of phrenology, the theory that the mind was divided into various faculties physically located in different parts of the brain. This theory would find a ready audience in Whitman, a poet preoccupied with the body, the soul, and their connection. The writings and publications of premier American phrenologists Orson and Lorenzo Fowler, surveyed in this project, rhetorically mediated emerging conceptions of the brain-embodied …

The Representation Of Nonmonogamy On Feminist Blogs, Caitlin M.

Dissertations, Theses, and Capstone Projects

When young women look to enhance their understanding or knowledge about sexuality and relationships they often seek out internet resources. Young women, who are looking for knowledge that challenges norms surrounding relationships and sexuality, can go to feminist blogs to discuss and discern these topics. Therefore, it is important to note what these blogs are offering the women who read them and how the blogs challenge compulsory norms in our society.

This thesis will combine a study of content pertaining to nonmonogamy on feminist blogs and a literary analysis of cyberfeminist theories. Through these findings I will determine what information …

Computational Analysis Of Gene Expression And Connectivity Patterns In The Convoluted Structures Of Mouse Cerebellum, Tao Zeng

Computer Science Theses & Dissertations

One significant difference between evolved mammalian brains and other species is that mammalian brains exhibit increasingly convoluted structures in the cerebral cortex. Groove and ridge shaped structures named gyri and sulci expand surface area of cerebral cortex, making more functions possible. Prior studies using neuroimaging techniques such as dMRI and DTI have revealed that neural fibers are heavily connected to gyri comparing to those connected to sulci, such macro-scale experiments indicates that gyri are involved in large scale information processing while sulci process information locally. However, molecular and cellar level evidences, namely, gene expression pattern and its resulting neuronal connectivity …

Range Extension Of The Macroalgae Anadyomene Stellata (Wulf. In Jacquin) C. Agardh And Re-Appearance Of Caulerpa Sertularioides (S. G. Gmel.) M. Howe In The Lower Laguna Madre, Texas, Hudson R. Deyoe, Joseph L. Kowalski

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

We report one new species of macroalgae, Anadyomene stellata, for the Lower Laguna Madre of Texas, and range extensions that have occurred in the past 16 years for this and four other green algae. Anadyomene stellata occurs only as an epiphyte on the red macroalgae, Digenia simplex. Caulerpa sertularioides has not been seen in the Lower Laguna Madre since 1962. It has either been present in cryptic habitats for 50 years near the Lower Laguna Madre or has recently expanded its range again into the Lower Laguna Madre. Ecological consideration of the presence of these species is discussed.

The Social Environment, Apoe-E4, And Dementia: The Social Environment As A Moderating Factor Among Individuals Genetically Predisposed To Develop Dementia, Judith L. Poey

Graduate Doctoral Dissertations

Many studies have shown a relationship between the APOE-e4 allele and dementia, as well as a relationship between the social environment and dementia. However, relatively little investigation into the potential moderating effect of the social environment on the relationship between the APOE-e4 allele and cognitive well-being has been reported. Further, studies that did examine these relationships typically have employed clinical populations, along with regional and non-U.S. samples. This study contributed to the research literature, in part, by using the first U.S. nationally representative sample of older adults that included clinical diagnosis of cognition and dementia (Aging, Demographics, and Memory Study …

Y- Box Protein 2 (Ybx2) Is A Major Mrna Specific Regulator Of Translation In Spermatogenesis And The Translational Regulation Of The Sperm Mitochondria Associated Cysteine Rich Protein (Smcp) Mrna, Tamjid A. Chowdhury

Graduate Doctoral Dissertations

Spermatogenesis is the process by which diploid stem cells differentiate into haploid male gametes, spermatozoa. As haploid cells differentiate into spermatozoa, they undergo profound changes in morphology and physiology, including total reorganization of chromatin in the nucleus which results in the inability to synthesize new mRNAs about one week before the differentiation of sperm is complete. Consequently, many mRNAs, such as the protamine 1 (Prm1) mRNA and sperm mitochondria-associated cysteine rich-protein (Smcp) mRNA, are transcribed in early haploid spermatogenic cells and stored as translationally inactive messenger ribonucleoprotein particles (free-mRNPs) for several days to a week before the mRNA is translated …

Engaging Youth: Linking Design And Implementation Choices Of Out-Of-School Time Programs In Boston To The Development Of Political Engagement Attitudes In Youth Age 14 To 18, Felicia M. Sullivan

Graduate Doctoral Dissertations

Tens of thousands of youth in communities across the United States are engaged every day in out-of-school time (OST) programs. These young people seek opportunities to recreate and socially engage, enhance academic and leadership skills, express themselves creatively, explore important issues in their communities, and work toward affecting change. These programs provide important institutional learning environments in which young people begin to assimilate their roles as political actors and citizens. As the delivery of social services and public programs has increasingly devolved from the government to the nonprofit sector, these programs also shape how young people come to understand their …

Does Increased Family Income Reduce Fade Out Of Preschool Gains?, Colin C. Rose

Graduate Doctoral Dissertations

The current study examines the connection between a change of family income and the retention of academic gains for children in low-income households who have attended a center-based preschool program. These children are often shown to lose the academic advantage they gain during preschool as they move through k-12 education in a phenomenon called fade out. A theoretical framework was constructed positing that material and psychological effects of poverty inhibit the ability of these families to support and maintain growth during this critical time when children are highly nested in the family unit.

Treating family income as a causal risk …

Exploring The Link Between Otolith Growth And Function Along The Biological Continuum In The Context Of Ocean Acidification, Eric D. Wilcox Freeburg

Graduate Doctoral Dissertations

Oceans are acidifying as atmospheric CO₂ is drawn down. This process, known as ocean acidification (OA), is well known and documented. Over the next 100 years, pH of the surface ocean is projected to decrease by up to 0.35 units. This CO₂ draw down has a direct effect on dissolved inorganic carbon (DIC) balance in the ocean. OA is expected to impact calcifying organisms that rely on constituencies of the DIC system, specifically carbonate ion [CO₃2-]. It is clear that externally calcified structures, such as coral skeletons, bivalve shells, etc., will be significantly affected as pH, …

School of Dentistry Faculty Research and Publications

The orthodontic profession is constantly seeking to improve and optimize the aesthetics of orthodontic wires since the introduction of aesthetic brackets. Nickel-titanium (NiTi) wires since their introduction to orthodontics (Andreasen and Hilleman, 1971) have been extensively researched in vitro and are used as an initial levelling and aligning archwire because of its properties of springback and superelasticity (Burstone et al., 1985; Miura et al., 1986; Leu et al., 1990; Bishara et al., 1995; Bradley et al., 1996; Biermann et al., 2007; Berzins and Roberts 2010). Aesthetic wires are usually either coated NiTi wires or composite wires of reinforced polymers. Shape …

Investr: An R Package For Inverse Estimation, Brandon M. Greenwell, Christine M. Schubert Kabban

Faculty Publications

Inverse estimation is a classical and well-known problem in regression. In simple terms, it involves the use of an observed value of the response to make inference on the corresponding unknown value of the explanatory variable. To our knowledge, however, statistical software is somewhat lacking the capabilities for analyzing these types of problems. In this paper, we introduce investr (which stands for inverse estimation in R), a package for solving inverse estimation problems in both linear and nonlinear regression models.
