Primary Utricle Structure Of Six Halimeda Species And Potential Relevance For Ocean Acidification Tolerance, Katherine E. Peach, Marguerite S. Koch, Patricia Blackwelder, Debbie Guerrero-Given, Naomi Kamasawa

Marine & Environmental Sciences Faculty Articles

Variations in utricle morphology may be responsible for different tolerances to ocean acidification (OA) within the macroalgal genus Halimeda, an important sediment producer on reefs. However, differences in species’ utricle morphology and their relationship to calcification and crystal formation have not been well articulated. In the present study, we characterized the utricle morphologies of six Halimeda species. Primary utricle ultrastructure was quantitatively and qualitatively compared to tissue inorganic content and crystal microstructure. Morphologies differed across species and several morphometric relationships were revealed. Primary utricle size (r²=0.70) and diffusion pathway length (r²=0.87) had inverse relationships with …

Academic Voice In Scholarly Writing, Garry Gray

The Qualitative Report

Tensions across disciplines and methodologies over what constitutes appropriate academic voice in writing is far from arbitrary and instead is rooted in competing notions of epistemology, representation, and science. In this paper, I examine these tensions as well as address current issues affecting academic voice such as gender bias and the rise of social media. I begin by discussing reflexivity in research and then turn to the ways in which personal-reflexive voice has been hidden and revealed by academic writers. I also illustrate how the commercialization of academic science intersects with the use of distant-authoritative voice in sometimes corrupting ways. …

Ocular Sensory Dominance And Viewing Distance, Karen Squier

Student Theses, Dissertations and Capstones

Abstract Purpose: It is not clear as to whether sensory dominance is affected by test distance. Jiang et al previously reported that that the sensory dominant eyes may be affected by refractive error; however this study was done at a near distance only (60 cm). In this study, we investigated the effect of two different test distances (near, 60 cm vs distance, 6 meters) on the laterality of ocular dominance. Methods: Ocular sensory dominance was quantified in 60 subjects with a technique that involves the dichoptic presentation of a Mondrian noise and a Gabor patch. The threshold to detect the …

Comparison Of Three Clinical Tests Of Accommodation To Hofstetter's Norms To Guide Diagnosis And Treatment, Marc Brian Taub

Student Theses, Dissertations and Capstones

Purpose. It has been documented previously that the push up (PU) and pull away (PA) methods overestimate accommodative amplitude (AA), while the minus lens-to-blur (MLB) method underestimates it. It also has been shown that the PU and PA methods produce similar results. We sought to compare data obtained from these three clinically used methods to determine AA in children and young adults with base-line normative data predicted by Hofstetter.

Methods. Ninety healthy subjects (mean 11.7 years, range: 6-36 and 50F/40M), split into two groups, children (mean 9.8 years, range: 6-13 and 38F/22M) and young adults (mean 25.5 years, range: 21-36 …

Moral Reasoning And Moral Emotions Linking Hoarding And Scrupulosity, Keith Lit

Theses and Dissertations

Hoarding and scrupulous OCD are part of the Obsessive-Compulsive and Related Disorders, which are characterized by obsessional preoccupation and ritualistic behavior. Prior research has found a statistical relationship between hoarding and scrupulosity after controlling for these common factors, suggesting the existence of other features shared by these two disorders. Clinical accounts and empirical research of hoarding and scrupulosity suggest three such shared factors: a tendency to experience intense guilt and shame, rigid moralistic thinking, and general cognitive rigidity. However, results of the current study show that, although both hoarding and scrupulosity were related to cognitive rigidity and a tendency to …

The Influence Of Trauma, Locus Of Control, And Health-Related Quality Of Life On A Child’S Self-Worth, Anita Alexander

Theses and Dissertations

Previous literature has shown that childhood trauma and adverse experiences are related to a wide range of negative outcomes that can span into adulthood (e.g., low self-worth, poor physical health, and increased likelihood of co-morbid psychological symptoms). However, a gap remains in the existing literature regarding early interventions that may target complicated outcomes (i.e., self-esteem and self-worth) while the survivor is still in childhood. This paper attempts to elucidate the impact that traumatic childhood experiences may have on self-worth, and the importance of implementing targeted intervention before the child reaches adulthood. Therefore, an extensive review was first conducted to gain …

Ptsd Subtypes, Depressive Presentation, Dissociation, And Cognitive Appraisals And Their Impact On Cardiovascular Reactivity Responses To Stress, Dyona Augustin

Theses and Dissertations

Both posttraumatic stress disorder (PTSD) and major depressive disorder (MDD) are related to an increased risk for cardiovascular disease (CVD), with links to ischemic heart disease, myocardial infarction, cardiac mortality, and other cardiac conditions. Given that these disorders are associated with increased medical costs, disability, and employer burden, research has investigated which factors increase the likelihood that one will develop CVD. While one hypothesis suggests that individuals who exhibit exaggerated responses to stress are at greater risk of developing CVD, individuals with PTSD/depression have been shown to exhibit both exaggerated and blunted stress responses. The purpose of the present study …

The Er Retention Protein Rer1 Promotes Alpha-Synuclein Degradation Via The Proteasome, Hyo-Jin Park, Daniel Ryu, Mayur Parmar, Benoit I. Giasson, Nikolaus R. Mcfarland

HPD Articles

Abnormal accumulation of α-synuclein (αSyn) has been linked to endoplasmic-reticulum (ER) stress, defective intracellular protein/vesicle trafficking, and cytotoxicity. Targeting factors involved in ER-related protein processing and trafficking may, therefore, be a key to modulating αSyn levels and associated toxicity. Recently retention in endoplasmic reticulum 1 (RER1) has been identified as an important ER retrieval/retention factor for Alzheimer's disease proteins and negatively regulates amyloid-β peptide levels. Here, we hypothesized that RER1 might also play an important role in retention/retrieval of αSyn and mediate levels. We expressed RER1 and a C-terminal mutant RER1Δ25, which lacks the ER retention/retrieval function, in HEK293 and …
