Intermolecular Multiple Quantum Coherences Enable Accurate Thermal Imaging of Red Bone Marrow During Thermal Therapy of Bone Metastases

Prostate and breast cancers are two of the most common types of cancer in the United States, and those cancers metastasize to bone in more than two thirds of patients. Recent evidence suggests that thermal therapy is effective at treating metastatic bone cancer. For example, thermal therapy enables targeted drug delivery to bone, ablation of cancer cells in bone marrow, and palliation of bone pain. Thermal therapy of bone metastases would be greatly improved if it were possible to image the temperature of the tissue surrounding the disease, which is usually red bone marrow (RBM). Unfortunately, current thermal imaging techniques are inaccurate in RBM.

This dissertation shows that many of the difficulties with thermal imaging of RBM can be overcome using a magnetic resonance phenomenon called an intermolecular multiple quantum coherence (iMQC). Herein, iMQCs are detected with a magnetic resonance imaging (MRI) pulse sequence called multi-spin-echo HOMOGENIZED with off resonance transfer (MSE-HOT). Compared to traditional methods, MSE-HOT provided ten-fold more accurate images of temperature change. Furthermore, MSE-HOT was translated to a human MRI scanner, which enabled imaging of RBM temperature during heating with a clinical focused ultrasound applicator. In summary, this dissertation develops a MRI technique that enables thermal imaging of RBM during thermal therapy of bone metastases.

El papel de la red latinoamericana de etnomatemática en la conformación de una comunidad académica

El presente trabajo tiene como objetivo dar a conocer a los educadores matemáticos y a los etnomatemáticos la existencia y la labor que ha desempeñado, en sus primeros cinco años, la Red Latinoamericana de Etnomatemática (RELAET) en América Latina, en la conformación y consolidación de una comunidad académica interesada en los aspectos sociales y culturales de la Educación Matemática.

[Organiser of Stirling's Red Buildings Conference for the Twentieth Century Society]

The aim of the conference is to review the three 'Red Buildings' with experts who have studied their history and their performance, and to discuss their future. Work is due to take place on the Leicester and Oxford buildings in the relatively near future, and technical knowledge can be shared in a context of understanding the design intention. Also to celebrate Stirling and Gowan's careers from a broader perspective and to assert the value of looking after these special buildings as assets for the future. The speakers in the afternoon session are people who knew the two architects well, and in some cases worked for them. [From University of Leicester]
