Biophan Receives Patent on Improved Medical Device Safety Under MRI Oct 4, 2005
Biophan's latest patent is one of a wide set of technologies developed to eliminate patient risks caused by the combination of these devices and the MRI signals and improve the image quality of these devices in MRI. Other Biophan technologies may be used to enhance the MRI visualization of interventional surgical tools that would otherwise be invisible under MRI. This eliminates the need for x-ray imaging to guide these procedures, limiting patient exposure to ionizing radiation and toxic... (Yahoo Finance -- Medical Equipment & Supplies)
What's New in Breast Health? Sep 28, 2005

Checking early for prostate cancer saves men's lives Sep 25, 2005
Asked to choose between surgery and the more complicated prospect of radiation therapy, in which the cancerous area is dosed with concentrated amounts of ionizing radiation, Gilroy says he felt most comfortable with the treatment that "seemed more finalized." For advanced cases of prostate cancer, however, professional opinions of effective treatments vary considerably. Some of the procedures in use today are chemotherapy, hormonal therapy and experimental treatments employing drugs, vaccines... (Chariho Times, RI)
Response teams lack manpower, test shows Sep 19, 2005

It is widely used in industry for scanning underground rivers but can also be used in dirty bombs. (Globe and Mail -- NationalTP)
The radioresistance kinase TLK1B protects the cells by promoting repair of double strand breaks Sep 13, 2005
Overexpression of TLK1B, a spliced variant of the TLK1 mRNA, in a model mouse cell line increases their resistance to ionizing radiation (IR) or the radiomimetic drug doxorubicin, also likely due to changes in chromatin remodeling. TLK1B is translationally regulated by the availability of the translation factor eIF4E, and its synthesis is activated by IR. The reason for this mechanism of regulation is likely to provide a rapid means of promoting repair of DSBs. (BioMed Central)
Bright Young Stars in Trumpler 14 Sep 10, 2005
In the meantime, the young, massive stars have a profound influence on their environment through the ionizing effects of their light, and the high-speed winds of particles that are pushed away from their surfaces by the intense radiation. Shock waves that develop in these winds can heat gas to millions of degrees Celsius and produce intense X-ray sources. (Universe Today)

Lake Shore's latest NASA project a smashing success Aug 14, 2005
The temperature sensors crafted by Lake Shore for Deep Impact were capable of working at minus 560 degrees Fahrenheit, while withstanding ionizing radiation and surviving the shaking that occurs during a rocket launch. Alas, some of those instruments are forever lost, embedded into Tempel 1 with the rest of the spacecraft that created the crater. (Columbus Business First, OH)

Folate system correlations in DNA microarray data Aug 5, 2005
For cells exposed to ionizing radiation, transient increases in both pathways are consistent with DNA damage driven dNTP demand, and a steadily decreasing backdrop is consistent with radiation induced cell cycle arrest. By and large, folate model based flux predictions paralleled these findings, the main differences being a gain of correlation information for the TEL-AML1 leukemia data, and the loss of one interesting inference, namely, that RNA repair driven DNPS precedes DNA repair driven DNTS...
