Method and composition for detection of proteolytic products and diagnosis of malignant neoplastic disease
Tumor invasion and metastasis is accompanied by significant activations of specific proteolysis enzymes. Tumor area is known to have increased infiltration of immunoglobulins G (“IgG”), so IgG may undergo proteolysis in this area. Serine proteases usually cleave peptide bonds between positively charged amino acids lysine and arginine. Since the intact PLG molecules as well as its fragments have lysine binding sites, they can bind to damaged IgG or fragments thereof with free C-terminal lysine that can appear in a circulation after proteolysis in the malignant tumor area. In the present invention we demonstrated the increased binding of damaged IgG or fragments thereof with free C-terminal lysine to fragments of PLG in samples from patients with breast cancer, ovarian cancer, lung cancer, colorectal cancer, prostate cancer vs. samples from healthy donors, and thus we proposed a novel diagnostic method. |

Power cable health monitoring method
A power cable monitoring method which can be used to measure the mechanical state of health of subsea power cables.

This force is predominantly axial. The strength of the F0 signal is used as an indicator of strain in the cable, where changes over time can be used to monitor the mechanical integrity of the cable structure. 2F0 signals are complex sums of axial, radial and tangential forces which are difficult to analyze. The 2F0 signal is therefore predominantly used to normalize the F0 signal. |
