PURPOSE To evaluate the effectiveness of mitomycin C (MMC) in preventing recurrence of pterygium following conjunctival autograft transplantation (CAT). Ki-67 antigen to evaluate epithelial cell proliferation and fibroblast nuclear kariometry were used to assist treatment evaluation. METHODS Twenty-nine patients with recurrent pterygium were divided into three groups: Group (G) 1--CAT and pla...

The present study aimed at analysing the intensity of apoptosis, as related to the expression of pro- and anti-apoptotic cellular markers (cas-3, MT, Ki-67 antigen), and at evaluating their expression in relation to the survival time of patients with colorectal adenocarcinoma. Material for the studies was obtained from 40 patients with primary colorectal adenocarcinomas (G2, T3N0M0), treated at...

It has been claimed that the commercially available Ki-67 monoclonal antibody recognizes a nuclear antigen which is solely expressed in cycling cells. Therefore, at present, Ki-67 is increasingly used as a tool in evaluating growth fractions (GFs) of human tumors. Here we describe specific patterns in the expression and topological distribution of this antigen during the cell cycle in MCF-7 hum...

Metallothionein (MT) is a low molecular weight protein, which participates in differentiation and proliferation of normal and tumour cells. In some malignant tumours (mammary, renal, ovarian cancers), its increased expression is thought to represent an unfavourable prognostic factor. Non-small-cellular lung cancers (mainly squamocellular cancer and adenocarcinoma) are characterised by ill-defin...

Two cases of Brenner tumor of the vagina were encountered in postmenopausal asymptomatic women who presented with polypoid lesions measuring 0.5 and 1.2 cm, respectively, in the upper and mid-vagina. DNA flow cytometry in one tumor showed a diploid histogram, and Ki-67 (MIB-1) proliferation marker was very low in both tumors. To the best of our knowledge, only two vaginal Brenner tumors have be...

The chemical name of the title compound in the paper by Kia, Fun & Kargar [Acta Cryst. (2009), E65, m289] is corrected.[This corrects the article DOI: 10.1107/S1600536809005078.].
