Biomechanical Testing Of Two-Level Cervical Disc Arthroplasty, Laura J. Gilmour
Biomechanical Testing Of Two-Level Cervical Disc Arthroplasty, Laura J. Gilmour
Theses and Dissertations (ETD)
In vitro biomechanical studies comparing two-level cervical disc arthroplasty with two-level fusion were completed using an established cadaveric cervical spine model. Three conditions were tested: non-instrumented, instrumented with two-level fusion (C5-C6 and C6-C7), and instrumented with two-level arthroplasty (C5-C6, C6-C7) using the Prestige Low-Profile (Medtronic Sofamor Danek, Memphis TN) or ProDisc-C (Synthes Spine, West Chester PA) prosthetic disc. Specimens were tested non-destructively in physiologic flexion-extension, lateral bending, and axial rotation to an end-limit load of 3-Nm or 45o rotation. Rotations at the superior, implanted, and inferior motion segment units (MSU) of the instrumented conditions were normalized to the non-instrumented condition …

Biomedical Imaging and Biosignal Analysis Laboratory
A micofluidic system is provided that includes a substrate, a first microchannel disposed in the substrate for providing a reactant to a reaction zone, a second microchannel disposed in the substrate, the third microchannel providing fluid communication between the first and second microchannels. The system also typically includes first and second electrodes, positioned at opposite ends of the second microchannel, for providing an electric field within the second microchannel. In operation, when the reactant is in the reaction zone, a reaction product is produced having a net electric charge different from the electric of the reactant.

Demographic Change And Response: Social Context And The Practice Of Birth Control In Six Countries, Sangeeta Parashar, Harriet B. Presser, Megan L. Klein Hattori, Sara Raley, Zhihong Sa
Department of Sociology Faculty Scholarship and Creative Works
This paper expands on Kingsley Davis’s demographic thesis of change and re- sponse. Specifically, we consider the social context that accounts for the primacy of particular birth control methods that bring about fertility change during specific time periods. We examine the relevance of state policy (including national family planning programs), the international population establishment, the medical profession, organized religion, and women’s groups using case studies from Japan, Russia, Puerto Rico, China, India, and Cameroon. Some of these countries are undergoing the second demographic transition, others the first. Despite variations in context, heavy reliance on sterilization and/or abortion as a means …

Manuscripts, Articles, Book Chapters and Other Papers
BACKGROUND: Pyloric stenosis, the most common surgical condition of infants, is treated by longitudinal myotomy of the pylorus. Comparative studies to date between open and laparoscopic pyloromyotomy have been retrospective and report conflicting results. To scientifically compare the 2 techniques, we conducted the first large prospective, randomized trial between the 2 approaches.
METHODS: After obtaining IRB approval, subjects with ultrasound-proven pyloric stenosis were randomized to either open or laparoscopic pyloromyotomy. Postoperative pain management, feeding schedule, and discharge criteria were identical for both groups. Operating time, postoperative emesis, analgesia requirements, time to full feeding, length of hospitalization after operation, and complications …

Preliminary Results For A Monocular Marker-Free Gait Measurement System, Jane Courtney, Annraoi Depaor
Preliminary Results For A Monocular Marker-Free Gait Measurement System, Jane Courtney, Annraoi Depaor
Articles
This paper presents results from a novel monocular marker-free gait measurement system. The system was designed for physical and occupational therapists to monitor the progress of patients through therapy. It is based on a novel human motion capture method derived from model-based tracking. Testing is performed on two monocular, sagittal-view, sample gait videos – one with both the environment and the subject’s appearance and movement restricted and one in a natural environment with unrestricted clothing and motion. Results of the modelling, tracking and analysis stages are presented along with standard gait graphs and parameters.

The structure of the type I tetraheme cytochrome c3 from Desulfovibrio desulfuricans G20 was determined to 1.5 A˚ by X-ray crystallography. In addition to the oxidized form, the structure of the molybdate-bound form of the protein was determined from oxidized crystals soaked in sodium molybdate. Only small structural shifts were obtained with metal binding, consistent with the remarkable structural stability of this protein. In vitro experiments with pure cytochrome showed that molybdate could oxidize the reduced cytochrome, although not as rapidly as U(VI) present as uranyl acetate. Alterations in the overall conformation and thermostability of the metal-oxidized protein were investigated …
Forensic Nursing: Death Investigation, Lauren Palazzo
Forensic Nursing: Death Investigation, Lauren Palazzo
Senior Honors Projects
Forensic Nursing is a fairly new exciting nursing specialty. Television shows such as CSI portray forensic nurses and investigators in a less than realistic manner. Forensic nursing and investigation are exciting fields to specialize in, but the role of the forensic nurse and investigator are often misunderstood. For my project I wrote a research paper on forensic nursing, joined the international association of Forensic nurses, attended the international conference in washington dc and set in on a few meetings with a board, including lawyers, represenatives from the rape crisis center, clinical managers from W&I ED, nurses, NP’s, etc. in discussing …

There are many reports about the associations between blood lipids, body mass index (BMI) and dietary cholesterol intakes both within the individual and between related individuals. The purpose of this descriptive research project was to investigate the relationships between LDL and HDL cholesterols, body mass index and dietary cholesterol intakes for a sample of African American (AA) mothers and their daughters and to attempt to separate the contribution of genetic versus environmental factors. Mother and daughter participants (n =42 and 66, respectively) were 12-14-hours fasted when blood samples were drawn, heights and weights measured, and 24 hour food recalls completed.
Laparoscopic Surgery In Children--Anaesthetic Considerations, Aliya Ahmed
Laparoscopic Surgery In Children--Anaesthetic Considerations, Aliya Ahmed
Department of Anaesthesia
Laparoscopic surgery has several advantages over conventional surgery for the patient. An increasing number of diagnostic and surgical procedures are being done laparoscopic not only in adults but also in paediatrics patients. In addition to the routine anaesthetic considerations for any surgical patient, the choice of the anaesthetic technique in patients undergoing laparoscopic procedures should consider the patient's underlying cardio respiratory functions induced by the pneumoperitoneum and carbon dioxide [CO2] insufflations. This article describes the physiological alterations induced by laparoscopic procedures in children and the anaesthetic implications of laparoscopic in the paediatric patient population.

We present a hybrid committee classifier for computer-aided detection (CAD) of colonic polyps in CT colonography (CTC). The classifier involved an ensemble of support vector machines (SVM) and neural networks (NN) for classification, a progressive search algorithm for selecting a set of features used by the SVMs and a floating search algorithm for selecting features used by the NNs. A total of 102 quantitative features were calculated for each polyp candidate found by a prototype CAD system. 3 features were selected for each of 7 SVM classifiers which were then combined to form a committee of SVMs classifier. Similarly, features …

Colonie polyps appear like elliptical protrusions on the inner wall of the colon. Curvature based features for colonie polyp detection have proved to be successful in several computer-aided diagnostic CT colonography (CTC) systems. Some simple thresholds are set for those features for creating initial polyp candidates, sophisticated classification scheme are then applied on these polyp candidates to reduce false positives. There are two objective functions, the number of missed polyps and false positive rate, that need to be minimized when setting those thresholds. These two objectives conflict and it is usually difficult to optimize them both by a gradient search. …
