Sealed Source Disposal And National Security – Problem Statement And Solution Set
While gamma rays have been a reliable source, the isotopes, primarily cobalt-60 and cesium-137, used to generate these gamma rays have come under heavy scrutiny worldwide in recent years. To quote the abstract of a recent publication, “Recent fears of terrorism have...

Reduction of Vibrio Vulnificus in Pure Culture, Half Shell and Whole Shell Oysters by X-Ray
Mahmoud BS, Coastal Research & Extension Center, Mississippi State University, Pascagoula, 39567, USA. bm547@msstate.edu Abstract: The purpose of this investigation was to study the inactivation effect of X-ray treatments on inoculated Vibrio vulnificus in pure...
Suppression of Radiation-Induced Salivary Gland Dysfunction by IGF-1
AbstractBackground Radiation is a primary or secondary therapeutic modality for treatment of head and neck cancer. A common side effect of irradiation to the neck and neck region is xerostomia caused by salivary gland dysfunction. Approximately 40,000 new cases of...
Insect Pest Control News – Joint FAO/IAEA Programme Nuclear Techniques in Food and Agriculture, 2009
Continuing difficulty in obtaining and shipping isotopic irradiators has made evaluation of X irradiation as an alternative to gamma radiation more pressing. Work on the evaluation of the RS 2400 X ray irradiator has continued with the manufacturer supplying us with...
Dose Characterization of the Rad Source 2400 X-Ray Irradiator for Oyster Pasteurization
Wagner JK, Dillon JA, Blythe EK, Ford JR., Department of Nuclear Engineering, Texas A&M University, College Station, TX 77843-3133, USA. jenkoop@gmail.com Abstract: The RS 2400’s cylindrical X-ray source yields dose rates high enough to allow the irradiator to...
X-Ray-Induced Sterility in Aedes albopictus (Diptera: Culicidae) and Male Longevity Following Irradiation
Authors: Yamada, H.1, 2; Parker, A. G.2; Oliva, C. F.3, 4, 2; Balestrino, F.5; Gilles, J.R.L.2 Source: Journal of Medical Entomology Abstract: The mosquito Aedes albopictus (Skuse, 1895) is a potent vector of several arboviral diseases, most notably chikungunya and...
Sterile Insect Technique: A Model for Dose Optimization for Improved Sterile Insect Quality

Pericytes and Endothelial Precursor Cells: Cellular Interactions and Contributions to Malignancy
Abstract: Tumor vasculature is irregular, abnormal, and essential for tumor growth. Pericytes and endothelial precursor cells (EPC) contribute to the formation of blood vessels under angiogenic conditions. As primary cells in culture, pericytes and EPC share many...
Expression of common chromosomal fragile site genes, WWOX/FRA16D and FHIT/FRA3B is downregulated by exposure to environmental carcinogens, UV, and BPDE but not by IR
Abstract: Common chromosomal fragile sites are unstable genomic loci susceptible to breakage, rearrangement, and are highly recombinogenic. Frequent alterations at these loci in tumor cells led to the hypothesis that they may contribute to cancer development. The two...
The Sesquiterpene Lactone Parthenolide Induces Apoptosis of Human Acute Myelogenous Leukemia Stem and Progenitor Cells
Abstract: Recent studies have described malignant stem cells as central to the initiation, growth, and potential relapse of acute and chronic myelogenous leukemia (AML and CML). Because of their important role in pathogenesis, rare and biologically distinct leukemia...
Passive and Active Mechanisms Trap Activated CD8+ T Cells in the Liver
Abstract: The liver is a site where activated CD8(+) T cells are trapped and destroyed at the end of an immune response. The intrahepatic accumulation of activated murine TCR transgenic CD8(+) T cells was significantly reduced when either ICAM-1 or VCAM-1 was blocked...
