GeneCards (www.genecards.org) is a comprehensive, authoritative compendium of annotative information about human genes, widely used for nearly 15 years. Its gene-centric content automatically mined and integrated from over 80 digital sources, resulting in web-based deep-linked card each >73 000 gene entries, encompassing the following categories: protein coding, pseudogene, RNA gene, genetic locus, cluster uncategorized. We now introduce Version 3, featuring speedy sophisticated search...
New materials of emerging technological importance are single-walled carbon nanotubes (SWCNTs). Because SWCNTs will be used in commercial products huge amounts, their effects on human health and the environment have been addressed several studies. Inhalation studies vivo submerse applications vitro described with diverging results. Why some indicate a strong cytotoxicity do not is what we report here. Data from A549 cells incubated fake cytotoxic effect within MTT assay after 24 h that...
Nanosilver is one nanomaterial that currently under a lot of scrutiny. Much the discussion based on assumption nanosilver something new has not been seen until recently and advances in nanotechnology opened completely application areas for silver. However, we show this analysis form colloidal silver used more than 100 years registered as biocidal material United States since 1954. Fifty-three percent EPA-registered products likely contain nanosilver. Most these applications are...
BackgroundHumans have been exposed to fine and ultrafine particles throughout their history. Since the Industrial Revolution, sources, doses, types of nanoparticles changed dramatically. In last decade, rapidly developing field nanotechnology has led an increase engineered with novel physical chemical properties. Regardless whether this exposure is unintended or not, a careful assessment possible adverse effects needed. A large number projects carried out assess consequences...
Graphing graphene: Because the naming of graphene-based materials (GBMs) has led to confusion and inconsistency, a classification approach is necessary. Three physical-chemical properties GBMs have been defined by GRAPHENE Flagship Project European Union for unequivocal these (see grid).
Nanoparticle exposure in utero might not be a major concern yet, but it could become more important with the increasing application of nanomaterials consumer and medical products. Several epidemiologic vitro studies have shown that nanoparticles can potential toxic effects. However, also offer opportunity to develop new therapeutic strategies treat specifically either pregnant mother or fetus. Previous mainly addressed whether are able cross placental barrier. transport mechanisms underlying...

Efficient drug delivery is essential for many therapeutic applications. Some cell-penetrating peptides, peptide mimetics, and peptoids express transport function that, however, lack in most cases specific intracellular destination. In this study, carrier-peptoids with either amino or guanidinium side chains, were investigated regard to their cellular uptake, toxicity, localization. Transport specifically the cytosol nuclei was observed, thus providing a powerful tool targeted delivery.
Abstract Background During production and processing of multi-walled carbon nanotubes (MWCNTs), they may be inhaled enter the pulmonary circulation. It is essential that interactions with involved body fluids like surfactant, blood others are investigated, particularly as these could lead to coating tubes affect their chemical physical characteristics. The aim this study was characterize possible coatings different functionalized MWCNTs in a cell free environment. Results To simulate first...
A comprehensive in vitro assessment of two commercial metal oxide nanoparticles, TiO2 and ZnO, was performed using human monocyte-derived macrophages (HMDM), dendritic cells (MDDC), Jurkat T cell leukemia-derived line. nanoparticles were found to be non-toxic whereas ZnO caused dose-dependent death. Subsequently, global gene expression profiling identify transcriptional response underlying the cytotoxicity by nanoparticles. Analysis done with doses 1 µg/ml 10 after 6 24 h exposure....
