Influence of Nanoparticles on the Nervous Tissue Properties

Reshetov I.V., Chissov V.I., Sukharev S.S., Timoshenko V.Y., Sidletskiy V.Y., Forsh P.A., P.A.Hertzen Moscow Research Oncological Institute, RU

Interaction between the nanoparticles and nervous tissue in the process of the damage healing is the object of study in the present work. Laboratory animal (rat) was put into deep narcosis. The Nervus ischiadicus was [...]

In Vitro Diagnosis and Analysis of the Potential Effects of Carbon Nanotube Exposure on the Human Respiratory System

Bowen E., Purser F., Park Y.B., Lee J.S., Kwon S., Utah State University, US

Recent discoveries of various forms of carbon nanostructure have stimulated researches on their applications and hold promise for applications in medicine and many other related engineering areas. While carbon nanotubes (CNT’s) are already being produced [...]

Monte Carlo Multi-Criteria Risk Analysis of Single Wall Carbon Nanotube Production Processes Under Uncertain Manufacturing Costs, Occupational Health Risks, and Regulatory Standards

Ok Z.D., Isaacs J.A., Benneyan J.C., Northeastern University, US

Considerable uncertainty exists regarding full-scale manufacturing costs, occupational risks, and probable future regulatory standards for various single wall carbon nanotube (SWNT) manufacturing processes. Monte Carlo models have been developed to investigate these implications and compare [...]

Experimental evaluation of individual protection devices against nanoaerosols:

Golanski L., Rouillon F., Guiot A., Bernard S., Tardif F., CEA, FR

Analysts have estimated that the worldwide market for nanoparticles will be about 340 billion Euro in 2011 which would rank it alongside the automobile and microelectronic industries. However, potential impact of these new materials on [...]

Nanomaterials down the drain: perception and reality

Sellers K., Bergeson L.L., AMEC, US

The fate of nanoparticles in commercial products at the end of product life is not entirely clear. This uncertainty, coupled with the unknowns regarding the potential for risks to human health and the environment, could [...]

Shin D.C., Jang J.Y., Yang J-Y, Kim C.S., Kim S-H, Choi I.H., Lim Y.W., Kim C.S., Kim S-H, Lee G.T., Yonsei University, KR

This study was undertaken to address the current deficient knowledge of cellular response to nano sized particle exposure.[4] The aim of this study was to investigate the in vitro responses of human bronchial epithelial cells [...]

Effects-Based Risk Assessment of Emerging and Existing Nanomaterials

Chan-Remillard S., Kapustka L., Goudey S., Golder Associates Ltd. & HydroQual Laboratories Ltd., CA

Nanotechnology has been compared to the industrial revolution in its scope of applications and ability to dramatically transform new and existing technologies. Nanotechnology is a quickly emerging field where the toxicological effects on human and [...]

Development and Application of an Exposure-based Framework for Assessing Nanomaterial Safety

Long C.M., Gradient Corporation, US

Although the Project on Emerging Nanotechnologies estimates that there are already over 500 nanotechnology-based consumer products on the market, few published data are available to support thorough nanomaterial safety assessments. To address questions of product [...]

Differential Cytotoxicity of Metallic Oxide Nanoparticles in Mammalian Cells

Lai J.C.K., Lai M.B., Jandhyam S., Dukhande V.V., Bhushan A., Daniels C.K., Leung S.W., Lai J.C.K., Lai M.B., Idaho State University, US

Nanomaterials have been increasingly used in industrial applications (e.g., drug delivery, additives to drugs and cosmetics). Because of their wide use, occupational exposure to nanomaterials and nanoparticles may pose as health risks. Recent studies have [...]

Silicon Dioxide Nanoparticles Exert Dissimilar Cytotoxic Effects on Mammalian Cell Types

Jandhyam S., Lai J.C.K., Lai M.B., Dukhande V.V., Bhushan A., Daniels C.K., Leung S.W., Lai J.C.K., Lai M.B., Idaho State University, US

Applications of nanomaterials (e.g., silicon dioxide (SiO2) nanoparticles) are ubiquitous. Thus, environmental and occupational exposure to these nanoparticles could pose potential health risk. SiO2 microparticles are toxic in animals in vivo and SiO2 nanoparticles are [...]
