Role Of Meibum And Tear Phospholipids In The Evaporative Water Loss Associated With Dry Eye., Samiyyah M. Sledge Dec 2021

Role Of Meibum And Tear Phospholipids In The Evaporative Water Loss Associated With Dry Eye., Samiyyah M. Sledge

Electronic Theses and Dissertations

It is generally believed that the tear film lipid surface film inhibits the rate of evaporation (Revap) of the underlying tear aqueous. It is also generally believed that changes in the composition of the tear film lipid layer is responsible for an increase in Revap in patients with dry eye. Both of these ideas have never been proven. The purpose of the current studies was to test these ideas. Revap was measured in vitro gravimetrically. Lipid spreading was measured using Raman spectroscopy and microscopy. The influence of the following surface films on the Revap of the sub phase of physiologically …


A Literature Review On The Development Of Upper Limbs In Humans, Anh T. Phan Sep 2021

A Literature Review On The Development Of Upper Limbs In Humans, Anh T. Phan

The Cardinal Edge

The development of tetrapod upper limbs shares an evolutionary origin and has been adapted and specialized for different functions for different species, such as flight in birds, swimming and balance in sea mammals, and coordination and grabbing objects in humans. The basis of tetrapod limb development has common developmental patterns, starting with the formation of the limb bud via Sonic hedgehog (Shh) signaling, where later developmental steps are modified for specialized functions. This review covers the basic developmental patterns of mammalian tetrapod development seen in humans, beginning with the formation of the limb bud, to the axis development of the …

Seen In Science: Lgbtq+ Inclusivity In Anatomy & Physiology Texts, Harshini Sirvisetty, Kat Ray King, Linda Catherine Fuselier

Undergraduate Arts and Research Showcase

Biology is unique from other science disciplines in that concepts taught in core classes can inform our student’s understanding of sex and gender. A biology major encounters lessons on sex determination, sexual reproduction, and sex characteristics in their courses. The language used in these units matters. It is imperative that educators consider how the language, examples, and content that we use in classrooms drive (or not) inclusivity for gender- and sexuality-diverse (GSD) (aka LGBTQ+) individuals. We chose to analyze four college-level human anatomy/physiology (AP) textbooks for GSD population inclusivity. We adopted a queer theory framework to critically examine how sex, …


Effects Of Step Training On The Kidneys Following Spinal Cord Injury In Rats., Pradeepa Poudyal Dec 2014

Effects Of Step Training On The Kidneys Following Spinal Cord Injury In Rats., Pradeepa Poudyal

Electronic Theses and Dissertations

Detrusor-sphincter dyssynergia after chronic spinal cord injury (SCI) leads to over-distention, high bladder pressures and vesico-ureteric reflux into the kidney, resulting in repeated infections and pyelonephritis. Given the importance/limited knowledge of SCI effects on the upper urinary tract, this study assessed expression of two proteins in the kidneys of contused (T9) male rats relative to controls that are indicative of tissue stress/damage (TGFβ, CD11b). The impact of two therapeutic rehabilitation strategies, 60 minutes of step training and general exercise, was then assessed on these protein levels relative to non-trained SCI controls, plus the effectiveness of a shorter training duration (30 …


Boundary Contour Based Surface Representation., Yong Su Dec 2014

Boundary Contour Based Surface Representation., Yong Su

Electronic Theses and Dissertations

We receive most information about our surrounding space and objects through the eyes. To reconstruct the 3D space and objects in the visual system from the 2D retinal images, surface representation must be a critical intermediate stage in the visual processing stream. It is hypothesized in the dissertation that the visual system represents textured surface by a border-to-interior strategy: boundary contours would be encoded first and then border-ownership assignments would be resolved. This process would solve the related problems such as figure-ground segregation, surface depth relationship, occlusion, transparency, etc. As a result, the boundary contours of the surfaces would be …
