Eco-Interoception: What Plants, Fungi And Protista Have Taught My Body, Sara Riley Dotterer

Art Theses and Dissertations

To me, ecology is the relational, full-body awareness that I am made up of and deeply connected to everything around me; and for better or worse, this is reciprocal. I form ecotones, an ecological transitional zone between two ecosystems, with the world around me. I use this ecotonal lens to blur binaries and dissolve boundaries between me and the world “outside my body.” During my Masters of Fine Arts at Southern Methodist University, I have continuously explored and represented the lives of various more-than-human species outside of my body, including plants, fungi and protista through an ecotonal lens. Although these …

Anatomy And Physiology Preparatory Course Textbook (2nd Edition), Carlos Liachovitzky

Open Educational Resources

The goal of this preparatory textbook is to give students a chance to become familiar with some terms and some basic concepts they will find later on in the Anatomy and Physiology course, especially during the first few weeks of the course.

Organization and functioning of the human organism are generally presented starting from the simplest building blocks, and then moving into levels of increasing complexity. This textbook follows the same presentation. It begins introducing the concept of homeostasis, then covers the chemical level, and later on a basic introduction to cellular level, organ level, and organ system level. This …

Impact Of 17-Beta Estradiol And Moderate-Intensity Exercise On Mesenteric Arterial Function Of Uc Davis Type-2 Diabetes Mellitus Rats, Md Rahatullah Razan

University of the Pacific Theses and Dissertations

The studies in this dissertation were designed to investigate the impacts of estrogen (17-β estradiol/E2) and moderate-intensity exercise (MIE) on the mesenteric arterial (MA) function of the University of California Davis type-2 diabetes mellitus (UCD-T2DM) Rat model. Our recent report suggests that diabetes impairs MA vasorelaxation in both sexes of the UCD-T2DM model. Particularly, we reported that MA from prediabetic male rats showed a greater impairment compared to that in prediabetic females. However, when females become diabetic, they exhibit a greater vascular dysfunction than males. Therefore, the aim of the first study was to investigate whether female sex hormone, specifically …

Diabetes Debunked: What You Need To Know, Maggie Hutson

Honors Theses

The goal of this Honors creative project is to encourage health literacy in populations who are curious about Type 2 Diabetes or have Type 2 Diabetes. From personal experience, I have seen noncompliance in diabetics and wondered why since it is a serious, progressive disease. After researching, I found that some diabetics do not understand the scope of their disease, especially since many of the dangerous complications that arise from Type 2 Diabetes do not present until later in the disease when it is too late. For my senior project, I decided to write an educational paper as a supplement …

Human Anatomy And Physiology Preparatory Course (1st Edition), Carlos Liachovitzky

Open Educational Resources

The overall purpose of this preparatory course textbook is to help students familiarize with some terms and some basic concepts they will find later in the Human Anatomy and Physiology I course.

The organization and functioning of the human organism generally is discussed in terms of different levels of increasing complexity, from the smallest building blocks to the entire body. This Anatomy and Physiology preparatory course covers the foundations on the chemical level, and a basic introduction to cellular level, organ level, and organ system levels. There is also an introduction to homeostasis at the beginning.

Roles Of Dopamine Receptor On Chemosensory And Mechanosensory Primary Cilia In Renal Epithelial Cells, Viralkumar S. Upadhyay, Brian S. Muntean, Samred H. Kathem, Jangyoun J. Hwang, Wissam A. Aboualaiwi, Surya M. Nauli

Pharmacy Faculty Articles and Research

Dopamine plays a number of important physiological roles. However, activation of dopamine receptor type-5 (DR5) and its effect in renal epithelial cells have not been studied. Here, we show for the first time that DR5 is localized to primary cilia of LLCPK kidney cells. Renal epithelial cilia are mechanosensory organelles that sense and respond to tubular fluid-flow in the kidney. To determine the roles of DR5 and sensory cilia, we used dopamine to non-selectively and fenoldopam to selectively activate ciliary DR5. Compared to mock treatment, dopamine treated cells significantly increases the length of cilia. Fenoldopam further increases the length of …

Sirtuins, Nuclear Hormone Receptor Acetylation And Transcriptional Regulation, James R. Whittle, Michael J. Powell, Vladimir M. Popov, L. Andrew Shirley, Chenguang Wang, Richard G. Pestell

Department of Cancer Biology Faculty Papers

Endocrine signaling via nuclear receptors (NRs) is known to play an important role in normal physiology as well as in human tumor progression. Hormones regulate gene expression by altering local chromatin structure and, thereby, accessibility of transcriptional co-regulators to DNA. Recently it has been shown that non-histone proteins involved in hormone signaling, such as nuclear receptors and NR co-activators, are regulated by acetylation, resulting in their altered transcriptional activity. NAD-dependent protein deacetylases, the sirtuins (Sir2-related enzymes), directly modify NRs. Because sirtuins have been shown to regulate tumor cellular growth, aging, metabolic signaling and endocrine hormone signaling, they might play a …

Cyclin D1 Repression Of Nuclear Respiratory Factor 1 Integrates Nuclear Dna Synthesis And Mitochondrial Function., Chenguang Wang, Zhiping Li, Yinan Lu, Runlei Du, Sanjay Katiyar, Jianguo Yang, Maofu Fu, Jennifer E Leader, Andrew Quong, Phyllis M Novikoff, Richard Pestell

Department of Cancer Biology Faculty Papers

Cyclin D1 promotes nuclear DNA synthesis through phosphorylation and inactivation of the pRb tumor suppressor. Herein, cyclin D1 deficiency increased mitochondrial size and activity that was rescued by cyclin D1 in a Cdk-dependent manner. Nuclear respiratory factor 1 (NRF-1), which induces nuclear-encoded mitochondrial genes, was repressed in expression and activity by cyclin D1. Cyclin D1-dependent kinase phosphorylates NRF-1 at S47. Cyclin D1 abundance thus coordinates nuclear DNA synthesis and mitochondrial function.

Regulation Of Collagenase Gene Expression By Il-1 Beta Requires Transcriptional And Post-Transcriptional Mechanisms, Matthew P. Vincenti, Charles I. Coon, Oneil Lee, Constance E. Brinckerhoff

Dartmouth Scholarship

Interleukin-1 beta is believed to contribute to the pathophysiology of rheumatoid arthritis by activating collagenase gene expression. We have used a cell culture model of rabbit synovial fibroblasts to examine the molecular mechanisms of IL-1 beta-mediated collagenase gene expression. Stimulation of rabbit synovial fibroblasts with 10 ng/ml recombinant human IL-1 beta resulted in a 20-fold increase in collagenase mRNA by 12 h. Transient transfection studies using collagenase promoter-CAT constructs demonstrated that proximal sequences responded poorly to IL-1 beta, possibly due to insufficient activation of AP-1 by this cytokine. More distal sequences were required for IL-1 beta responsiveness, with a 4700 …
