Final Aiha Report On Semi Project In Kazahkstan, Armin Weinberg
Final Aiha Report On Semi Project In Kazahkstan, Armin Weinberg
Works on Radiation Effects: 1990-2020
An executive summary of the last year of the AIHA supported activities that were supported as a part of the payback (Project Sapphire) for dismantling nuclear weapons in Kurchatov. An extremely meaningful set of mutually agreed upon objectives by both sides served as a solid base to establish a multidimensional effort. See more at Armin Weinberg, PhD Papers and its finding aid.
Disinfection Of Dentin By Intracanal Laser Irradiation: An In Vitro Model, Silvia Cristina Mafra Cecchini
Disinfection Of Dentin By Intracanal Laser Irradiation: An In Vitro Model, Silvia Cristina Mafra Cecchini
Loma Linda University Electronic Theses, Dissertations & Projects
A possible cause for root canal failure is the persistence of bacteria that have colonized dentinal tubules. To reduce this risk and, if possible, to also shorten the time consuming endodontic therapy, new equipment and materials are constantly being introduced. The aim of the present investigation was to study the effect of disinfection of dentinal tubules by intracanal laser irradiation using an in vitro model. The groups irradiated by various lasers were compared with calcium hydroxide, a material frequently used as intracanal medication between appointments. Freshly extracted, intact bovine incisors were used. The root cementum was removed and the teeth …
Connexin-32 Contributes To Radiation Resistance In Thyroid Follicles, Da-Thao Dinh Tran
Connexin-32 Contributes To Radiation Resistance In Thyroid Follicles, Da-Thao Dinh Tran
Loma Linda University Electronic Theses, Dissertations & Projects
The objective of this study was to examine the role of gap junctions in the radiation resistance of thyroid follicles. The question of whether gap junctional intercellular communication plays an important role in the “contact effect”, wherein cells in direct apposition are more resistant to the damaging effects of radiation, has been debated for years. We used the Fischer rat thyroid cell line (FRTL-5) to carry out our experiments. This thesis is divided into two parts: 1) characterization of gap junctional properties in FRTL-5 cells and, 2) exposure of these cells to radiation.
We found that, unlike primary thyroid cells, …
Detection And Modeling Of Radiation Induced Effects In Tissues By Dielectric Spectroscopy, Dorin A. Todor
Detection And Modeling Of Radiation Induced Effects In Tissues By Dielectric Spectroscopy, Dorin A. Todor
Physics Theses & Dissertations
The work presented here is applied physics research in the field of radiation treatment. We address the development of a new and innovative method, in vivo and possibly non-invasive, for tumor and healthy tissues control during and after the radiation treatment. The radiation treatment is delivered in an almost standardized manner for particular classes of tumors. The large variance in the individual radio sensitivity of healthy tissues and tumors often leads to local recurrence of neoplastic growth and/or distant metastatic disease which often remains untreated. The method is based on the measurement and analysis of electrical impedance data in …
