Background: Expansion of the use of magnetic fields in metals, mining, transport, research, and medicine industries has led to a discussion about the effects of magnetic fields and whether their strength is negligible. The aim of this study was to investigate the effects of magnetic field on the viability and proliferation rate of HeLa cells. Materials and methods: We studied the effects of ma...
Shiga toxins (Stxs) are bacterial virulence factors produced by Shigella dysenteriae serotype 1 and Escherichia coli strains. Stxs are critical factors for the development of diseases such as severe bloody diarrhea and hemolytic uremic syndrome. Additionally, Stxs trigger the secretion of pro- inflammatory cytokines and chemokines, particularly in monocytes or macrophages. The inflammatory cyto...
Cervical cancer ranks third in incidence worldwide and is the most frequent gynecological developing countries. This study aimed to investigate effect of crocin on resistance HELA/Ara-C cells chemo-agent Ara-C. which was defined as Ara-C-resistant HELA cell line, were treated with crocin. After that, proliferation, apoptosis, cycle assay examined by MTT assay, AO/EB staining, flow cytometry, re...
The HeLa cell line is the oldest, most widely distributed, permanent human cell line. As a nearly ubiquitous inhabitant of laboratories using tissue culture techniques, its aggressive growth characteristics make it a problematic contaminant that can overgrow less robust cell lines. Consequently, HeLa contamination is common in both the research laboratory and cell line repository contexts, and ...
Aim: to identify biological interactions between proliferating fibroblasts and HeLa cells in vitro. Materials and Methods: Fibroblasts were isolated from both normal and tumour human tissues. Coverslip co-cultures of HeLa and fibroblasts in various ratios with medium replacement every 48 h were studied using fixed cell staining with dyes such as Giemsa and silver staining, with immunochemistry ...
Background: Plants are a proven source of anti-tumor compounds and it is reasonable to assume that many such substances remain to be discovered. In Iranian folk medicine, ethanolic extract of the aerial parts of Daphne mucronata Royle is used against various skin disorders.Objective: In order to evaluate anti-neoplastic plants, we initiated a cytotoxic study using Daphne mucronata that is indig...
