ADAMTS13 activity and inhibitor.

Thrombotic thrombocytopenic purpura (TTP) is often associated with acquired or congenital deficiency of the von Willebrand factor-cleaving metalloprotease, ADMATS13 (Lammle B et al., J Thromb Haemost 2005;3:1663-1675; Schneppenheim et al., Blood 2003;101:1845-1850).

Intermediate filamentous proteins in adult granulosa cell tumors. An immunohistochemical study of 25 cases.

Adult granulosa cell tumors (AGCTs) are classified as sex cord-stromal tumors of the ovary. However, they may be confused with other primary ovarian neoplasms. Intermediate filaments, specifically vimentin and cytokeratins, have been identified in AGCTs by immunohistochemistry performed on frozen and formalin-fixed, paraffin-embedded tissue and two-dimensional electrophoresis.
