Thoracic index in the Negro
… were undertaken in order to determine the thoracic index, (i. e. the ratio of the antero-posterior to the transverse diameter) according to age and sex in the Negro, by means of a series of measurements made upon the living body. In addition, a number of observations were made to determine …

Imaging microcalcium in thoracic aortic disease
BACKGROUND: Disease of the thoracic aorta occurs in two major forms; atheroma and aneurysm formation. Both disease processes progress silently before catastrophic complications occur, such as stroke or aortic dissection. Current management strategies focus on preventative interventions which can …

The Biomechanics of Thoracic Skeletal Response
… impact collisions, it has been reported that thoracic injuries are the most common type of serious injury (AIS≥3) to vehicle occupants in both near side and far side crashes which do not involve a rollover. In addition, rib fractures are the most frequent type of thoracic injury observed in …

Advances in real-time thoracic guidance systems
Substantial tissue motion: >1cm) arises in the thoracic/abdominal cavity due to respiration. There are many clinical applications in which localizing tissue with high accuracy: <1mm) is important. Potential applications include radiation therapy, radio frequency ablation, lung/liver biopsies, and …

4D Study of Thoracic Cancer Radiation Treatment
… added uncertainty in the radiation treatment of thoracic malignancies due to an increase in the normal tissue irradiated and an uncertainty in the radiation coverage of the tumor. This results in a potential increase in complications from treatment and may be insufficient to ensure coverage of …

Scanned Ion Beam Therapy For Thoracic Tumors
… studied the robustness of dose distributions in thoracic targets to uncertainties in patient motion. Finally, we investigated whether using carbon-ion therapy instead of proton therapy would significantly reduce the predicted risk of second cancer in the breast for a sample of Hodgkin lymphoma …

Patient-specific thoracic endovascular aoratic repair (TEVAR)
Endovascular aortic repair (EVAR) is a minimally invasive procedure to treat aortic aneurysms. Current off-the-shelf devices may not fit the patient perfectly, potentially increasing the chance of post-operative complications. This project aims to provide proof of concept for rapidly creating …

Outcomes after thoracic endovascular aortic repair (TEVAR) in patients with traumatic thoracic aortic injuries (TTAI) - a single center retrospective review
Background: Blunt and penetrating traumatic thoracic aortic injuries constitute surgical emergencies that are attended with high mortality rates. Most patients do not survive long enough, post injury, to reach a hospital. On-site mortality rates may approach approximately 85%. Two main treatment …

Thoracic Radiotherapy Treatment Planning With Cine Pet/Ct
Purpose: Respiratory motion causes substantial uncertainty in radiotherapy treatment planning. Four-dimensional computed tomography (4D-CT) is a useful tool to image tumor motion during normal respiration. Treatment margins can be reduced by targeting the motion path of the tumor. The expense and …

Characteristics of Thoracic Organ Injuries in Frontal Crashes
… of airbags has not significantly reduced serious thoracic injury for belted occupants in frontal crashes. This thesis has investigated the effectiveness of airbags and the characteristics of residual thoracic organ injury incurred by belted occupants in vehicles equipped with airbags. This study …

Penetrating injuries of the thoracic aorta and its branches
Penetrating injuries of the intrathoracic great vessels are well recognized although uncommon. In the First World War no survivors with thoracic vascular injury were recorded among soldiers treated with penetrating injuries to the chest as recorded by Makins. The first record of successful repair …

DPN-linked isocitrate dehydrogenase from fly thoracic muscle mitochondria
… dehydrogenases have been identified in the thoracic muscle mitochondria from the face fly and the American cockroach. The DPN-linked enzyme from these two insects is closely related on the basis of chromatographic pattern. DPN-linked IDH has been isolated from face fly thoracic muscle …

Resident angiogenic mesenchymal stem cells from multiorgan donor thoracic aortas
… at identifying in situ and isolating MSCs from thoracic aortas of young and healthy heart-beating multiorgan donors. Immunohistochemistry performed on fresh and frozen human thoracic aortas demonstrated the presence of the vasculogenic zone between the media and the adventitial layers in which a …

A Journey Through The Thoracic Aorta: From Root To Arch
… the knowledge of pathology affecting the thoracic aorta so that it can help guide clinical management in the future. Aims: This thesis aims to investigate the effects of pathology on the aortic valve and thoracic ascending aorta through determination of: 1. The pathophysiology of proximal …

The Role of IGF-1 and Notch Signaling in Thoracic Malignancies.
<p>Thoracic malignancies are one of the deadliest of all cancers, being the leading cause of cancer death in the Western world. Thoracic malignancies arise from different tissues; however the most common are of epithelial (commonly referred to as non-small cell lung cancer, or NSCLC), …
