Background: Medulloblastoma is the most common malignant brain tumor in children. The important factors in predicting survival are the extent of disease, proliferation index of the tumor cells, histopathologic class and the age at diagnosis. The percentage of Ki-67 positive cells reflects the proliferation  of the cells and is one of the critical factors which determine the growth of the tumor....

This study aimed to investigate how the production process of metal impregnated biochars (MIBs) affects their selectivity in simultaneous adsorption organic matter and dissolved phosphorus from aqueous phase. MIBs were produced via a two-step pyrolysis procedure including impregnation oxides structure softwood-derived biochars, resulting copper-impregnated biochar (Cu-MIB) iron-impregnated (Fe-...

BACKGROUND Argyrophilic nucleolar organizer regions (AgNORs) and MIB-1 as proliferating activities have been applied separately to assess the malignant potential of cancer cells. We conducted staining of AgNORs and MIB-1 in 42 surgically-resected invasive breast carcinomas. MATERIALS AND METHODS Paraffin-embedded sections were used for double staining and the mean AgNOR counts in 100 MIB-1-po...

AIM To determine the interobserver variation in scoring presence and grade of vulvar intraepithelial neoplasia (VIN) in haematoxylin/eosin (H/E) slides, MIB 1 slides, and the combined use of H/E and MIB 1 slides. METHODS 10 slides were stained with H/E and MIB 1 with each of the following diagnoses: normal vulvar skin, VIN 1, VIN 2, and VIN 3. Six observers first scored the H/E slides separat...

Notch signaling pathway defines an evolutionarily conserved mechanism in cell-fate determination in a broad spectrum of developmental processes through local cell interactions. mind bomb (mib) encodes an E3 ubiquitin ligase that is involved in Notch activation through Delta ubiquitylation and internalization. To further dissect the function of Mib, two yeast two-hybrid screens for zebrafish Mib...

Purpose: A number of studies have indicated that the tumor proliferation marker MIB-1 and cell cycle inhibitor p27 expression are of prognostic importance in a variety of cancers. The present study was performed to evaluate the prognostic value of these molecules in Wilms’ tumors. Experimental Design: MIB-1 and p27 expressions were investigated by the means of immunohistochemical analysis of 62...
