Induction Of Immune Surveillance Of The Dysmorphogenic Lens., Caitlin M. Logan, Caitlin J. Bowen, A. Sue Menko
Induction Of Immune Surveillance Of The Dysmorphogenic Lens., Caitlin M. Logan, Caitlin J. Bowen, A. Sue Menko
Department of Pathology, Anatomy, and Cell Biology Faculty Papers
The lens has been considered to be an immune privileged site not susceptible to the immune processes normally associated with tissue injury and wound repair. However, as greater insight into the immune surveillance process is gained, we have reevaluated the concept of immune privilege. Our studies using an N-cadherin lens-specific conditional knockout mouse, N-cadΔlens, show that loss of this cell-cell junctional protein leads to lens degeneration, necrosis and fibrotic change, postnatally. The degeneration of this tissue induces an immune response resulting in immune cells populating the lens that contribute to the development of fibrosis. Additionally, we demonstrate that the lens …

Ros Control Mitochondrial Motility Through P38 And The Motor Adaptor Miro/Trak., Valentina Debattisti, Akos A. Gerencser, Masao Saotome, Sudipto Das, György Hajnóczky
Department of Pathology, Anatomy, and Cell Biology Faculty Papers
Mitochondrial distribution and motility are recognized as central to many cellular functions, but their regulation by signaling mechanisms remains to be elucidated. Here, we report that reactive oxygen species (ROS), either derived from an extracellular source or intracellularly generated, control mitochondrial distribution and function by dose-dependently, specifically, and reversibly decreasing mitochondrial motility in both rat hippocampal primary cultured neurons and cell lines. ROS decrease motility independently of cytoplasmic [Ca2+], mitochondrial membrane potential, or permeability transition pore opening, known effectors of oxidative stress. However, multiple lines of genetic and pharmacological evidence support that a ROS-activated mitogen-activated protein kinase (MAPK), p38α, is …
Understanding The Chondrogenic Potential Of Articular Chondrocytes, Krishna Sarma
Understanding The Chondrogenic Potential Of Articular Chondrocytes, Krishna Sarma
Theses & Dissertations
Articular cartilage is a smooth, visco-elastic, aneural, avascular tissue made of water, an exquisitely organized framework of proteoglycans, glycosaminoglycans, and collagen fibrils and articular chondrocytes. It’s beautiful organization and composition provide it with the flexibility and strength to cover, protect and lubricate the ends of long bones in a diarthrodial joint. Cartilage homeostasis relies on articular chondrocytes to translate the mechanical forces of daily activity into efficient remodeling of the extracellular matrix. Age, joint injury, or other insulting factors can progressively incapacitate articular chondrocytes, resulting in cartilage lesions that devolve to degenerative joint disease. Therefore, the central idea explored in …
Strength-Based Physiological Profiles Of Ncaa Division I Womens Basketball And Gymnastics Athletes: Implications For Injury Risk Assessment, Curtis Cazier
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
The purpose of this study was to provide a comprehensive strength-based physiological profile of women’s collegiate basketball and gymnastic athletes; and to make sport-specific comparisons for various isokinetic and maximal and rapid isometric strength characteristics of the knee flexor and extensor muscles. A focus on antagonist muscle balance (hamstrings to quadriceps ratios, H:Q) will help elucidate particular vulnerabilities in these at-risk female athletes. Fourteen Division I collegiate level women’s basketball and 13 women’s gymnastics athletes performed isokinetic and isometric strength testing of the knee extensors and flexors. Outcome measures included absolute and body mass normalized (relative) isokinetic and isometric peak …
New Paradigms In The Treatment Of Acute Complicated And Uncomplicated Type B Aortic Dissection, Eric S. Weiss
New Paradigms In The Treatment Of Acute Complicated And Uncomplicated Type B Aortic Dissection, Eric S. Weiss
Eric Weiss, MD, MPH
The treatment of acute type B aortic dissection is a rapidly evolving field, due in a large part to the advent of thoracic endovascular aortic repair (TEVAR). This review will summarize the current literature on the management of both complicated and uncomplicated type B dissections, with special attention paid to emerging evidence supporting earlier aggressive treatment.

Consecutive recruitment of 17 patients (14 males) awaiting OLT at a single tertiary hospital. Dietary intake, food behaviours and anthropometry were recorded at baseline, and 6 and 12 months post-transplant.
Results:
By 12 months, patients had gained on average 7.3% of body weight. The prevalence of overweight or obesity increased from baseline 53% …
A Deeper Look Into The Vastus Medialis: A Stabilizer For The Knee, Connie Nicole Barnes
A Deeper Look Into The Vastus Medialis: A Stabilizer For The Knee, Connie Nicole Barnes
Undergraduate Honors Capstone Projects
Anterior cruciate ligament tears are one of the most common injuries that occur, especially in female athletes. It requires surgery and months of physical therapy to get these athletes back in playing condition. The angle of women’s hips and lack of strength of inner quadriceps muscles enhances the risk of injuries to the knees. One specific muscle that is known for being a stabilizer of the knee and may help in preventing ACL tears is the vastus medialis. By understanding what exercises activate this muscle the most, conditioning plans and preventative workouts need to be created to help female athletes …

Introduction
Cytology is integral in the assessment of urothelial cell carcinoma (UCC). However, upper urinary tract (UUT) specimens are cytologically challenging due to limited tissue and reactive atypia. At our institution UUT biopsies are processed as cell blocks (CB). We compared our institution’s reporting system (IRS) with the recently proposed Paris System for Reporting Urine Cytology (PRS) (Table 1) in UUT specimens and correlated the findings with CB and follow-up resections.

Abstract
The presence of axonal spheroids is unusual in the absence of a clinical history of CNS injury. Nevertheless, increased numbers of axonal spheroids in the lower brainstem have been consistently observed in autopsied diabetic patients. A prospective comprehensive investigation of the density, size, and distribution of axonal spheroids in the brainstem and spinal cord was undertaken in 22 patients and correlated with comorbidities, age, and gender. In most cases, an increased density of axonal spheroids was identified within the nucleus gracilis of the lower brainstem. Moreover, the highest densities (p = 0.013) and circumferences (p = 0.002) of axonal …

Cartilaginous structures are at the core of embryo growth and shaping before the bone forms. Here we report a novel principle of vertebrate cartilage growth that is based on introducing transversally-oriented clones into pre-existing cartilage. This mechanism of growth uncouples the lateral expansion of curved cartilaginous sheets from the control of cartilage thickness, a process which might be the evolutionary mechanism underlying adaptations of facial shape. In rod-shaped cartilage structures (Meckel, ribs and skeletal elements in developing limbs), the transverse integration of clonal columns determines the well-defined diameter and resulting rod-like morphology. We were able to alter cartilage shape by …

Pathologic findings encountered during cadaver dissection provide an opportunity for integrating the preclinical basic sciences and encouraging critical thinking. The objective of this study was to determine whether it is possible to make a pathologic diagnosis of an unknown mass from an embalmed cadaver. Diagnoses would have to be based solely on gross and microscopic appearance of tissue, without clinical histories of the cadaveric donors. The tissue samples we removed from each mass were surprisingly well preserved and showed minimal autolysis. Indeed, some of the histological detail was as clear as may be found in any textbook. We were able …

The Reliability Of The Navicular Drop Test And Its Transferability To Dynamic Movement, Joshua Krispin
The Reliability Of The Navicular Drop Test And Its Transferability To Dynamic Movement, Joshua Krispin
Electronic Theses and Dissertations
Background: Navicular drop can be defined as the distance the navicular tuberosity moves from a standing weight bearing to a standing neutral position, as the subtalar joint moves from a relaxed position to a neutral position. Navicular drop is an important measurement for clinicians used to describe foot function, pronation, and excessive movement seen in several pathologies. Objective: The purpose of this study is to see if navicular drop is influenced by mode or speed of locomotion, if it is will there be other influences such as the forefoot and heel soft tissue, and will those factors influence those measures. …
