Abstract: In the setting of myocardial ischemia, recovery of myocardial function by revascularization procedures depends on the extent of coronary disease and myocardial scar burden. Currently, computed tomographic (CT) imaging offers superior evaluation of coronary lesions but lacks the capability to measure the transmural extent of myocardial… Continue reading

Significant toxic role for single-walled carbon nanotubes during normal embryogenesis – Corrected Proof
Abstract: In order to investigate the effect of SWCNTs in the embryo, we examined the outcome of SWCNTs in avian embryo at an early stage of development. We found that SWCNTs-treatment inhibits the angiogenesis of the chorioallantoic membrane (CAM) and in the chicken embryo. Moreover, we showed that SWCNTs can harm the normal development of the… Continue reading
New system to improve DNA sequencing
A sensing system developed at Cambridge is being commercialised in the UK for use in rapid, low-cost DNA sequencing, which would make the prediction and diagnosis of disease more efficient, and individualised treatment more affordable…. Continue reading
Guía OEPM: Patentes en nanotecnología
El número de solicitudes de patente europea para invenciones relacionadas con la nanotecnología se ha más que triplicado desde mediados de los años noventa.
Este folleto de la OEPM explica cómo iniciar la búsqueda de invenciones en el sector de la nanotecnología en bases de datos de patentes, y qué tener en cuenta si tiene previsto presentar una solicitud de patente de nanotecnología ante la Oficina Europea de Patentes.
Single low-dose un-adjuvanted HBsAg nanoparticle vaccine elicits robust, durable immunity – Corrected Proof
Abstract: Chitosan nanoparticles were evaluated as a vaccine delivery system for hepatitis B surface antigen (HBsAg) in the absence of adjuvant. Nano-encapsulated HBsAg (HBsAg chitosan-NP) was endocytosed more rapidly and efficiently by dendritic cells compared to soluble HBsAg. FRET analysis demonstrated that intact nanoparticles were taken up by… Continue reading
Dietary crystalline common-, micro-, nanoscale and emulsified nanoscale sitosterol reduce equally the cholesterol pool in guinea pigs, but varying nanosystems result in different sterol concentrations in serosal jejunum – Corrected Proof
Abstract: Due to hypocholesterolemic effects, sitosterol is used in functional foods and nanoscale dispersions. To investigate the influence of dietary sitosterol on sterol concentrations in Dunkin Hartley guinea pigs, seven groups consisting of eight animals each were fed either a basal diet (BD), a high-cholesterol diet (HC) or a… Continue reading
UK HSE posts guidance on controlling occupational exposure to manufactured nanomaterials
Including carbon nanotubes (CNTs) and other bio-persistent high aspect ratio nanomaterials (HARNs). The United Kingdom”s Health and Safety Executive (HSE) has posted a guidance document describing how to control occupational exposure to manufactured nanomaterials in the workplace…. Continue reading
Corrigendum to “Enhanced antiproliferative activity of Herceptin (HER2)-conjugated gemcitabine-loaded chitosan nanoparticle in pancreatic cancer therapy” [Nanomed Nanotechnol Biol Med. 2011;7:859–870]
The authors regret that in the earlier version of the article initially published, a typographical error and a minor unintentional mistake in Figures 3 (A) were observed. The errors have been corrected in the revised article. It is noteworthy that these changes do not alter the conclusion drawn from this study. The authors apologize to the readers… Continue reading
