Simultaneous hyperthermia-chemotherapy with controlled drug delivery using single-drug nanoparticles
We previously investigated the utility of μ-oxo N,N'- bis(salicylidene)ethylenediamine iron (Fe(Salen)) nanoparticles as a new anti-cancer agent for magnet-guided delivery with anti-cancer activity. Fe(Salen) nanoparticles should rapidly heat up in an alternating magnetic field (AMF), and we hypothesized that these single-drug nanoparticles would be effective for combined hyperthermia-chemother...
Abstract Background Thermal stressors in tropical aquaculture are unavoidable and cause many harmful effects. This study assessed the effects of ascorbic acid (AA) iron nanoparticles supplementation diet African catfish, Clarias gariepinus , exposed to hyperthermia-induced stress. C. juveniles weighing 6.89 ± 0.05 g were randomly distributed into plastic tanks 48 cm by 30 31 dimension at ten fi...
Background & Aim: Molecular imaging enables us to non-invasively visualize tissue microstructures and lesion characterization, allowing accurate diagnosis of diseases at early stages. A successful molecular imaging requires a nontoxic contrast agent with high sensitivity. Nowadays, a wide range of nanoparticles have been developed as contrast agents for medical imaging modalities. Here, we revi...
Since cancer cells produce large amounts of lactate via aerobic glycolysis and since an acidic pH has been shown to selectively enhance the cytotoxic effects of hyperthermia, we are examining the influence of cell exposure to drugs which inhibit lactate transport and lower intracellular pH upon cytotoxic effects of hyperthermia. Quercetin, a bioflavonoid that produces lactate transport inhibiti...
Magnetic nanoparticles attracted a great deal of attention in the medical applications due to their unique properties. The most exceptional property of magnetic particles is their response to a magnetic force, and this property has been utilized in applications such as drug targeting, bioseparation, contrast agents in magnetic resonance imaging (MRI) and heating mediators for cancer therapy. In...
As with other forms of psychological stress, conditioned fear causes an increase in body temperature. The mechanisms underlying this stress-induced hyperthermia are not well understood, but previous research suggests that nonshivering thermogenesis might contribute, as it does during cold exposure. The major source of nonshivering thermogenesis in the rat is brown adipose tissue (BAT), and the ...
BACKGROUND The ER chaperone GRP78/BiP is a homolog of the Hsp70 family of heat shock proteins, yet GRP78/BiP is not induced by heat shock but instead by ER stress. However, previous studies had not considered more physiologically relevant temperature elevation associated with febrile hyperthermia. In this report we examine the response of GRP78/BiP and other components of the ER stress pathway ...
