摘要： The identification and use of two major DNA-PKcs autophosphorylation sites. Threonine (T) 2609 and Serine (S) 2056, including antibodies specific for phosphorylated T2609 and 52056. Peptides and polynucleotides encoding same, that feature these two sites of phosphorylation. The antibodies do not bind to the unphosphorylated DNA-PKcs protein or peptide, thus providing diagnostic tools to monitor the effectiveness of treatments which target the DNA repair pathway of cancer cells, and the ability to intervene or inhibit in phosphorylation of T2609 or 52056, either through application of a drug or an antibody, to increase the radiosensitivity of cancer cells.

摘要： A voltage level shifting device for translating a lower operating voltage to a higher operating voltage includes a first input node coupled to a first pull down device and a second input node coupled to a second pull down device. The second node receives a complementary logic signal with respect to the first input node, the first and second input nodes associated with the lower operating voltage. A first pull up device is in series with the first pull down device and second pull up device is in series with the second pull down device, with the first and second pull up devices coupled to a power supply at the higher operating voltage. An output node is between the second pull down device and the second pull up device, the output node controlling the conductivity of the first pull up device. A clamping device is in parallel with the first pull up device, and configured to prevent the second pull up device from becoming fully saturated.

摘要： A voltage level translating circuit that allows low voltage signals to be translated to higher voltages, a design structure utilized in the design, manufacture, and/or testing of the voltage level translating circuit, and a method of manufacturing the voltage level translating circuit are described. The translating circuit utilizes two different voltage domains. The high voltage rail of the low voltage domain acts as the ground of the high voltage domain. The translating circuit also utilizes a voltage buffer electrically connected to the high voltage domain and to the low voltage domain to prevent the circuit devices in either domain from seeing too high of a voltage. The translating circuit allows the circuits after the translating circuit to work with signals utilizing the high voltage rail of the high voltage domain.
