Efficacy of Dipeptide-Coated Magnetic Nanoparticles in Lung Cancer Models Under Pulsed Electromagnetic Field.

Lung cancer is the leading cause of cancer deaths and the overall 5-year survival rate is less than 17%. Hyperthermia is an alternative approach for the treatment of lung cancer and is associated with fewer side effects. We employed ironoxide nanoparticles in inducing localized hyperthermia in lung cancer cells using a pulsed electromagnetic field (PEMF).

Molecular mechanism of anti-cancer activity of phycocyanin in triple-negative breast cancer cells.

Background: Triple-negative breast cancers represent an important clinical challenge, as these cancers do not respond to conventional endocrine therapies or other available targeted agents. Phycocyanin (PC), a natural, water soluble and non-toxic molecule is shown to have potent anti-cancer property.

Methods: In this study, we determined the efficacy of PC as an anti-neoplastic agent in vitro on a series of breast cancer cell lines.

Nanomedicine: towards development of patient-friendly drug-delivery systems for oncological applications.

The focus on nanotechnology in cancer treatment and diagnosis has intensified due to the serious side effects caused by anticancer agents as a result of their cytotoxic actions on normal cells. This nonspecific action of chemotherapy has awakened a need for formulations capable of definitive targeting with enhanced tumor-killing. Nanooncology, the application of nanobiotechnology to the management of cancer, is currently the most important area of nanomedicine.

Blood compatibility of iron-doped nanosize hydroxyapatite and its drug release.

Nanosize hydroxyapatite (nHAp) doped with varying levels of Fe(3+) (Fe-nHAp of average size 75 nm) was synthesized by hydrothermal and microwave techniques. The samples were characterized for physiochemical properties by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), inductively coupled plasma optical emission spectrometer (ICP-OES), transmission electron microscopy (TEM), vibrating sample magnetometer (VSM), mechanical and dielectric properties. The biological properties like hemocompatibility, antibacterial efficacy, in vitro bioactivity and the cell proliferation of the samples were determined.
