Factors Affecting Gingival Recession in the Esthetic Zone: A Human Cadaver Study
… recession to the following parameters in fresh cadavers: gingival thickness, buccal bone loss, buccal bone thickness, shape of bony dehiscence defect, and age. A secondary aim was to evaluate predictors for gingival recession.</p> <p>Sixteen fresh cadavers were used in this study. Gingival …

Biomechanical Comparison of Wire Circlage and Rigid Plate Fixation for Median Sternotomy Closure in Human Cadaver Specimens
… and anterior-posterior (transverse) shear in a cadaveric model. Methods: Forty-two fresh cadaver models were divided into three test groups: group A, B, and C. A cardiothoracic surgeon divided each cadaveric sternum longitudinally and repaired peristernal wires or one of two Sternalock …

Biomechanics of Eustachian Tube Dysfunction: From Mechanics to Assessment
… the mechanics of the ET is studied in both human and sheep cadaver specimens to gain a better understanding of the ET opening process. First, this research investigated the acoustics of the ET in a controlled environment using three models of the ET transmission line. Based on these results, …

Polypyrrole : an interactive substrate for bone regeneration
… from a donor site) and allografts (bone from human cadaver). However, these methods are plagued with disadvantages. There is a clear and urgent need to provide alternatives for regenerating and repairing bone. Bone is known to be one of the many connective tissues in the body that are …

Verification of the <i>Ex Vivo</i> Thiel Embalmed Model for Liver Treatment with Magnetic Resonance-guided Focused Ultrasound (MRgFUS) before Clinical Practice
… more favourable than the fresh or formalin-fixed cadavers, due to its long-lasting, tissue-mimicking properties, and limited health risks.<br/><br/>This thesis verified the Thiel embalmed liver, as a model for MRgFUS treatment before clinical practice, by using explanted organs and whole cadavers. …

Biomechanical Comparison of Lumbar Disc Replacements
… of motion and flexibility were obtained. Seven human cadaver lumbar spines (L1-S1) were tested in flexion, extension, left and right lateral bending, and left and right axial rotation. Testing conditions, in order, were the harvested state, ProDisc-L at L5-S1, Maverick at L5-S1, and a pedicle …

Models for Testing Contemporary Ultrasound Systems
… in medical simulation, soft-embalmed Thiel human cadaver models being considered for their suitability as a model for testing shear wave elastography and interventional ultrasound systems. The results indicate significant similarities between the Thiel-embalmed cadavers, and human's in-vivo …

Lateral and Posterior Dynamic Bending of the Mid-Shaft Femur: Fracture Risk Curves for the Adult Population
… injury risk functions for dynamic bending of the human femur in the lateral-to-medial and posterior-to-anterior loading directions. A total of 45 experiments were performed on human cadaver femurs using a dynamic three-point drop test setup. All 45 tests resulted in mid-shaft femur fractures with …

Microbial succession in human rib skeletal remains and fly-human microbial transfer during decomposition
Human decomposition is a dynamic process partially driven by the actions of microbes. It can be defined by the fresh, early decomposition, advanced decomposition, and skeletonization stages. The microbial communities that facilitate decomposition change in a predictable, clock-like manner, which …

Ethical issues relating to the 'donation' of human and animal organs for transplantation
… of two sorts of donors which are already in use: humans declared dead according to brain-based criteria and nonhuman animals. In the first chapter I attempt to provide a theoretical underpinning for the brainstem criterion of brain death. I also criticise certain rival theories. In the second …

Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) as a Biomonitoring Tool
… spectrometry (LA-ICP-MS) this research analyzed human cadaver hair for gadolinium and mice hair samples for cadmium. This project combined fundamental bench science (analytical chemistry and animal studies), and insight into exposures to an emerging contaminant. This study demonstrated the …

Proof of Concept and Evaluation of a Novel Implant Device for Plantar Plate Repair
… repair in anatomically relevant orientations. A human cadaver tissue model protocol was employed to evaluate the integrity of the native plantar plate tissue, a simulated conventional repair, and our novel implant fixation repair. These methodologies used uniaxial tensile testing with custom test …

Lymphocyte subset variability between human lymphoid tissues
… are in the lymphoid tissues. However, studies of human lymphocytes to date have primarily investigated cells from the blood, and lymphoid tissues remain poorly studied. This thesis explores the hypothesis that there is local variation of B cell subsets between the tissues that are …

A novel encapsulation favorably modifies the skin disposition of topically-applied N,N-diethyl-3-methylbenzamide (DEET)
… w/w) was confined. Measurements were made using human cadaver skin and modified Franz diffusion cells which allowed for simultaneous sampling of both skin absorption and evaporation. Quantitative DEET analysis was performed using HPLC. After 48 hours, microencapsulation led to a 30% reduction in …

Effects of Ca2+, microRNAs, and rosuvastatin on insulin-secreting beta cell function
… cells, rodent animal models, and islets from human cadaver donors has been used. Whole-cell patch clamp was used to study exocytosis measured as changes in cell membrane capacitance. In beta cells, biphasic exocytotic pattern was previously mainly attributed to insulin granule pool depletion. …

Using electrical stimulation responses to understand cochlear implant status
… I show how SCINSEVs can be used, both in a human cadaver model and in CI patients, as a visual tool to detect extracochlear electrodes and I introduce an automated detection and quantification tool for those clinicians less familiar with SCINSEVs. This measure might be able to prevent …
