Case Report: Hidden Posterior Dislocation Of The Clavicular Head, David F. Koziel

Rowan-Virtua Research Day

Reported is a case of a 24-year-old male who presented with left shoulder pain and decreased range of motion of the same shoulder upon awakening, diagnosed with a posterior dislocation of the proximal clavicle, with the clavicular head residing in the mediastinum. In the conscious, ambulatory, young adult it is arguably much more common for major bony trauma involving the upper extremity and shoulder to present with pain, deformity, and a known mechanism. This is an example that lacks all three of these characteristics and highlights the importance of details in the physical examination as well as clinical gestalt.

Overlooked Dental Disease In Cbct Imaging And The Impact Of Oral Radiologist Interpretation, Jared Fausnaught

Annual Research Symposium

This study aims to underscore the necessity for a comprehensive interpretation of Cone Beam Computed Tomography (CBCT) volume images obtained by dentists. The research demonstrates and quantifies potentially overlooked dental pathology, categorizing incidental findings into three groups: 1) requiring some form of treatment or follow-up, 2) necessitating follow-up (monitoring) only, and 3) demanding no further treatment or follow-up.

Rna Isolation In Duchenne Muscular Dystrophy (Dmd) Mice Models, Salem Abu Al-Burak

Undergraduate Student Research Internships Conference

Fibrosis is a progressive and typically irreversible disease process characterized by the excessive deposition of collagen in organs and in tissues of the musculoskeletal (MSK) system^1,2. This process, which causes loss of organ and tissue function, can be initiated by micro-traumas³, an excessive and/or prolonged immune response¹, the activation and proliferation of fibrosis-inducing progenitor cells⁴, and a pro-fibrotic extra-cellular microenvironment⁵. In parallel with the events that initiate fibrosis, genetic or environmental influences may cause cells and tissues to become predisposed to fibrosis development prior to initiation. This suggests that these …

Creating A Protein Chimera To Study Regulation Of Muscle Diversity, Shannon Scarboro

Symposium of Student Scholars

Creating a protein chimera to study regulation of muscle diversity.

Body muscles are made of many individual super-cells, called muscle fibers, that have distinct properties and determine every individual’s strength and endurance. Initially all muscle fibers have identical characteristics, but become differentiated into specific types in adults. The mechanism of such transition is not well understood, despite its obvious importance for shaping human physicality.

Remarkable conservation of the muscle tissue enables us to use fruit flies to study the mechanisms of muscle fiber diversity. We hypothesized that the transcription factor Mef2 acts as a molecular switch that activates structural genes …

Oral Contraceptives As Possible Acl Injury Prevention Method, Haley Schweizer

Capstone Showcase

ABSTRACT

Introduction: Anterior Cruciate Ligament (ACL) injuries are an upsetting setback for many athletes that require a long and costly recovery process. The injury rates are four times greater in women than men. Preventative measures that help to prevent ACL injuries are limited to stretching and strengthening. Therefore, this review aims to investigate if oral contraceptive [I] usage provides a possible new avenue for prevention of ACL injury [O] in young female athletes (ages 18-30) [P] compared to those that do not take oral contraceptives [C].

Methods: A literature review was performed though PubMed, Google Scholar, SCOPUS Database, and ClinicalKey …

The Role Of Osteocyte Estrogen Receptor Beta (Erβ) In Regulating The Skeletal Response To Mechanical Loading, Julia P. Townsend, Russell P. Main

The Summer Undergraduate Research Fellowship (SURF) Symposium

Estrogen’s biological functions are mediated by estrogen binding to estrogen receptors (ER). Understanding what role both ERα and ERβ have in bone maintenance and formation can contribute to possible treatment of osteoporosis. This study examined osteocyte specific deletion of ERβ in mice. The cross of ERβ-floxed mice with DMP1-8kb-Cre mice provided both experimental knockout mice as well as littermate control mice. At 24 weeks of age the left tibiae of all mice were mechanically loaded five days per week for two weeks to induce bone formation. Analysis of cortical bone was conducted using microcomputed tomography (microCT) to measure load-induced changes …
