Effect Of Posture On Acromiohumeral Distance With Arm Elevation In Subjects With And Without Rotator Cuff Disease Using Ultrasonography, Nitin Kalra
Theses and Dissertations
Objectives: To examine the effects of posture on subacromial (SA) space with arm elevation in patients with rotator cuff disease (RCD) and healthy subjects. Background: Poor posture has been linked to altered scapular mechanics, theorized to lead to excessive SA space narrowing. However, no study has examined the direct effects of posture on SA space using ultrasonography. We hypothesize that when compared to a neutral posture, upright posture will increase SA space and slouched posture will decrease SA space. Methods: Subjects with painful RCD (n=31) and healthy (n=29) shoulders participated. SA space was measured on ultrasound generated images using the …

Retinoic Acid Induced 1 Gene Analysis In Humans And Zebrafish, Bijal Vyas
Theses and Dissertations
Smith-Magenis syndrome (SMS) is a complex mental retardation syndrome caused by deletion of 17p11.2 region or mutation of the RAI1 gene (retinoic acid induced 1). Individuals with SMS typically exhibit speech and motor delays, mental retardation, characteristic craniofacial and skeletal anomalies, and a distinct neurobehavioral phenotype that includes sleep disturbances, stereotypes, and maladaptive and self-injurious behaviors. RAI1 is thought to be a transcription factor modulating the expression of genes involved in a variety of cellular functions. Previous studies have shown the RAI1 gene being induced by retinoic acid (RA), a derivative of vitamin A. RA plays a significant role in …
