Computed tomography (CT) showed a lymph node 47 mm in size that was located above the pancreas head and beneath the liver.

The covalent addition of nitric oxide (NO(•)) onto cysteine thiols, or S-nitrosylation, modulates the activity of key signaling proteins. The dysregulation of normal S-nitrosylation contributes to degenerative conditions and to cancer. To gain insight into the biochemical changes induced by low-dose ionizing radiation, we determined global S-nitrosylation(More)
