In vitro toxicity evaluation of single walled carbon nanotubes on human A549 lung cells.
This paper describes the in vitro cytotoxicity assessment of single walled carbon nanotubes (SWCNT) on A549 cells, a human lung cell line. Cellular viability was determined using the alamar blueExpand
A new approach to the toxicity testing of carbon-based nanomaterials--the clonogenic assay.
The cellular toxicity of three types of carbon nanoparticles, namely HiPco single-walled carbon nanotubes (SWCNT), arc discharge SWCNT and Printex 90 carbon black nanoparticles, was studied on threeExpand
Aquatic ecotoxicity of the selective serotonin reuptake inhibitor sertraline hydrochloride in a battery of freshwater test species.
Sertraline hydrochloride is a selective serotonin reuptake inhibitor (SSRI) widely prescribed to patients suffering from psychiatric disorders. Pharmaceutical products such as sertraline have beenExpand
Production of a signal by irradiated cells which leads to a response in unirradiated cells characteristic of initiation of apoptosis
This study investigated the ability of medium from irradiated cells to induce early events in the apoptotic cascade, such as mobilization of intracellular calcium, loss of mitochondrial membraneExpand
The Involvement of Calcium and MAP Kinase Signaling Pathways in the Production of Radiation-Induced Bystander Effects
Abstract Lyng, F. M., Maguire, P., McClean, B., Seymour, C. and Mothersill, C. The Involvement of Calcium and MAP Kinase Signaling Pathways in the Production of Radiation-Induced Bystander Effects.Expand
Spectroscopic analysis confirms the interactions between single walled carbon nanotubes and various dyes commonly used to assess cytotoxicity
The cytotoxicity of single walled carbon nanotubes was evaluated in the A549 human alveolar carcinoma cell line. Cell viability was assessed using the following indicator dyes, Commassie Blue, AlamarExpand
Reactive oxygen species (ROS) induced cytokine production and cytotoxicity of PAMAM dendrimers in J774A.1 cells.
The immunotoxicity of three generations of polyamidoamine (PAMAM) dendrimers (G-4, G-5 and G-6) was evaluated in mouse macrophage cells in vitro. Using the Alamar blue and MTT assays, a generationExpand
Single walled carbon nanotubes induce indirect cytotoxicity by medium depletion in A549 lung cells.
The ability of two types of single walled carbon nanotubes (SWCNT), namely Arc Discharge (AD) and HiPco single walled carbon nanotubes, to induce an indirect cytotoxicity in A549 lung cells by meansExpand
Rapid Androgen Actions on Calcium Signaling in Rat Sertoli Cells and Two Human Prostatic Cell Lines: Similar Biphasic Responses Between 1 Picomolar and 100 Nanomolar Concentrations1
Abstract Androgen-induced calcium fluxes and gap junctional intercellular communication (GJIC) were studied in three different cell types. A transient (2–3 min duration) increase in intracellularExpand
Reactive oxygen species-induced release of signalling factors in irradiated cells triggers membrane signalling and calcium influx in bystander cells
Purpose: The aim of this study was to elucidate the sequence of very early bystander signalling events and to determine the role of the different signalling molecules in both the production of theExpand
