Design and characterisation of casein coated and drug loaded magnetic nanoparticles for theranostic applications.

Theranostic systems enable early cancer diagnostic and treatment. In this work, we prepared Na-caseinate coated magnetic nanoparticles (MNP) to assess their capability as a theranostic system. This system enables monitoring by magnetic particle imaging (MPI), drug delivery and magnetic hyperthermia.

Colorimetric detection of oral bacteria using functionalized gold nanoparticles as a plasmonic biosensor array.

Early detection of specific oral bacterial species would enable timely treatment and prevention of certain oral diseases. In this work, we investigated the sensitivity and specificity of functionalized gold nanoparticles for plasmonic sensing of oral bacteria. This approach is based on the aggregation of positively charged gold nanoparticles on the negatively charged bacteria surface and the corresponding localized surface plasmon resonance (LSPR) shift.

E-Selectin Targeted Gold Nanoshells to Inhibit Breast Cancer Cell Binding to Lung Endothelial Cells.

Extravasation of circulating tumor cells (CTCs) from the vasculature is a key step in cancer metastasis. CTCs bind to cell adhesion molecules (CAMs) expressed by endothelial cells (ECs) for flow arrest prior to extravasation. While a number of EC-expressed CAMs have been implicated in facilitating CTC binding, this work investigated the efficacy of inhibiting cancer cell binding to human lung microvascular ECs via antibody blocking of E-selectin using antibody-functionalized gold nanoshells (NS).

[Transvaginal access for NOTES].

NOTES ("natural orifice transluminal endoscopic surgery") has the potential to optimize minimally invasive surgery. In gynecology there is extensive experience with the transvaginal approach to the abdominal cavity. It is easy to perform, closure is safe and there is little risk of infection.

Laparoscopic Toupet fundoplication.

This article and video presents our Toupet procedure. It is a modern adaptation of Toupet's original technique. Toupet described his technique of fundoplication in 1963 (Toupet, Mem Aca Chir 89:394, 1963).
