The impact of radiation-induced bystander effect (RIBE) is still not well understood in radiotherapy. RIBEs are biological effects expressed by nonirradiated cells near or far from the irradiated cells. Most radiological studies on cancer have been based biochemical characterization. However, biophysical investigation with label-free techniques to analyze and compare direct irradiation RIBE has...

The biological application of nanoparticles (NPs) is a rapidly developing area of nanotechnology that raises new possibilities in the treatment of human cancers. The cytotoxicity was evaluated by MTT and LDH assays. The apoptotic effect of free ICD-85 and ICD-85 NPs on HeLa cells was assessed using caspase-8 colorimetric assay. The MTT assay showed that ICD-85 NPs could enhance the in-vitro cyt...

It has been reported that latex and extracts of different species of Ficus are cytotoxic to some human cancerous cell lines. In this study, cytotoxicity of fruit and leaf extracts as well as the latex of Ficus carica L. on HeLa cell line were evaluated. Ethanolic extracts of leaves and fruits were prepared through percolation and ethyl acetate and dichloromethane extracts were prepared by reflu...

The objective of this study was to observe the apoptosis-inducing effect and mechanism of baicalin on human cervical cancer HeLa cells. The inhibitory effect of baicalin on the growth of HeLa cells was measured by MTT assay, and cell proliferation and migration was analyzed by cell scratch assay. Morphological changes of apoptotic cells were viewed by the light microscope and electron microscop...

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...

OBJECTIVE(S) Radiation effect induced in nonirradiated cells which are adjacent or far from irradiated cells is termed radiation-induced bystander effect (RIBE). Published data on dose-response relationship of RIBE is controversial. In the present study the role of targeted and bystander cells in RIBE dose-response relationship of two cell lines have been investigated. MATERIALS AND METHODS T...
