Six solid phases of [Mn(DMSO)6](ClO4)2 have been detected by differential scanning calorimetry. The phase transitions were found between the following solid phases: stable KIc ↔ stable KIb at TC5 = 225 K, metastable KIII ↔ metastable KII at TC4 = 322 K, stable KIb → stable KIa at TC3 = 365 K, metastable KII ↔ overcooled K0 at TC2 = 376 K and stable KIa → stable K0 at TC1 = 379 K. The title comp...
We determined estrogen receptor protein and carcinoembryonic antigen in cytosols prepared from 189 human breast carcinoma tissues, 85 benign or normal breast biopsies, and 101 tissue specimens metastatic from breast carcinoma. Carcinoembryonic antigen was observed in 70% of the primary carcinomatous tissues, 15% of the benign or normal specimens, and 51% of the metastases. Ninety-six of the 189...
BACKGROUND The present study aimed at evaluating the expression intensities of the Mcm-2 protein and Ki-67 antigen in squamocellular carcinomas of the oral cavity and comparing their prognostic value. MATERIALS AND METHODS Forty-nine patients, operated on and treated with radiotherapy for carcinoma of the oral cavity floor and/or the mobile part of the tongue, were retrospectively analyzed. ...
We investigated the staining characteristics of serrated polyps with abnormal proliferation (SPAP) using MIB-1 and MCM-2 to determine if they could provide assistance in delineating SPAPs from traditional hyperplastic polyps (HPs). Using published morphologic criteria we reviewed H&E slides of 107 polyps from 80 patients. Thirty-nine (36.4%) polyps met the criteria for SPAP Within a given regio...
In 1983, Gerdes, Schwab, Lemke and Stein reported upon a new monoclonal antibody which was generated by immunizing mice with nuclei of the Hodgkin lymphoma cell line L428. This antibody was found to label nuclei of proliferating cells including tumor cells. In their report the authors therefore concluded that “Ki-67 (a name derived from the city of Kiel where the authors worked, and the number ...
AIMS To compare the proliferative activity of intraepithelial melanocytes in primary acquired melanosis (PAM) without atypia and PAM with atypia by immunohistochemical staining for the Ki-67 antigen and the proliferating cell nuclear antigen (PCNA). METHODS Formalin fixed, paraffin embedded sections from 35 archival specimens of PAM without atypia (n = 19) and with atypia (n = 16) were studie...
This study investigated expression of proliferating cell nuclear antigen (PCNA), proliferation-associated nuclear antigen (Ki-67) and cyclooxygenase-2 (COX-2) in tissues of breast invasive ductal carcinoma, and analyzed the correlations between these indexes and X-ray features in mammography. A total of 90 patients who were admitted to Huangshi Central Hospital and diagnosed as breast invasive ...
Pituitary adenomas sometimes show rapid growth and recurrence, and about one third invade the structures surrounding the sella turcica. In an attempt to determine aggressive behavior at an early stage, we used the MIB-1 antibody to identify the Ki-67 antigen. The present study was designed to evaluate pituitary adenomatous tissue in terms of secretion and proliferation and to correlate the Ki-6...
