Uveal melanoma cell cycling, quantified by bromodeoxyuridine (BrdUrd)-labeling index and mitotic index, is predictive of tumor-related mortality. Serial sections from 36 formalin-fixed melanoma specimens were labeled with BrdUrd and stained with hematoxylin and eosin. All tumors were assessed for the area of highest cell cycling activity and counts for mitotic figures and BrdUrd labeling were p...

Distilled water (negative control), dimethyl sulfoxide (DMSO), ethyl methane sulfonate (EMS, positive 5% 10% doses V. E. extracts applied for 24 48 hours. Cytotoxicity genotoxicity by calculating %mitotic index %chromosomal abe...

The incidence of male breast cancer (MBC) is rising. Current treatment regimens for MBC are extrapolated from female breast cancer (FBC), based on the assumption that FBC prognostic features and therapeutic targets can be extrapolated to MBC. However, there is yet little evidence that prognostic features that have been developed and established in FBC are applicable to MBC as well. In a recent ...

BACKGROUND Cell proliferation is associated with the pathogenesis of cancer because it provides opportunities for accumulating genetic mutations. However, biomarkers of cell proliferation in response to environmental stimuli have not been adequately explored for breast cancer risk. METHODS In a case-control study of 200 breast cancer patients and 360 healthy controls, we investigated the asso...

Background: Most of the cytogenetic dosimetry, except Premature Chromosome Condensation assay, saturates at 6 Gy. Present studies are aimed to assess feasibility of simple CB-MN assay for prescreening of high dose accidental exposures. Materials and Methods: Human peripheral blood lymphocytes from two donors were gamma irradiated to different doses ranging from 0-15Gy, cultured for 72 h. Cytoch...

In this current study, antiproliferative effect of Hec1/Nek2 Mitotic Pathway inhibitor INH1 was investigated in adenocarcinomic human alveolar basal epithelial cells A549 and cervix carcinoma HeLa cell lines vitro. To end index values by xCELLigence Real‐Time Cell Analysis DP instrument, mitotic index, BrdU proliferation assay apoptotic analysis were used. The results the study showed that had ...

INTRODUCTION The term atypical pituitary adenoma (APA) was revised in the 2004 World Health Organization (WHO) classification of pituitary tumors. However, two of the four parameters required for the diagnosis of APAs were formulated rather vaguely (i.e., "extensive" nuclear staining for p53; "elevated" mitotic index). Based on a case-control study using a representative cohort of typical pitui...

A hyperproductive mucosal state in gluten-sensitive enteropathy has been proposed on the basis of an elevated mitotic index, but this parameter is dependent on the mitotic duration when used as an index of proliferative status. The mitotic duration was therefore measured in two control patients with normal villous mucosae and in two patients with the flat avillous mucosa of untreated gluten-sen...
