Melanoma is a cancer with a rising incidence, and metastatic disease is almost always lethal. We investigated the feasibility of targeting melanin, an intracellular melanocyte pigment, to deliver cytotoxic radiation to human melanoma cells in vivo by using a melanin-binding mAb (6D2). Nude mice bearing MNT1 pigmented human melanoma tumors were treated with mAb 6D2 labeled with 1.5 mCi (1 Ci = 3...
AIM Previously, we showed that radioimmunotherapy (RIT) for cryptococcal infections using radioactively labeled antibodies recognizing the cryptococcal capsule reduced fungal burden and prolonged survival of mice infected with Cryptococcus neoformans. Here, we investigate the effects of RIT on bystander mammalian cells. MATERIALS & METHODS Heat-killed C. neoformans bound to anticapsular antib...
No significant improvement in therapy of pancreatic cancer has been reported over the last 25 y, underscoring the urgent need for new alternative therapies. Here, we coupled a radioisotope, (188)Rhenium, to an attenuated (at) live Listeria monocytogenes (Listeria(at)) using Listeria-binding antibodies, thus creating a unique radioactive Listeria(at) (RL). We then demonstrated in a highly metast...
A series of eight Rhenium(I)-N-heterocyclic carbene (NHC) complexes of the general form [ReCl(CO)3(C^C)] (where C^C is a bis(NHC) bidentate ligand), [ReCl(CO)3(C^C)]2 (where C^C is a bis-bidentate tetra-NHC ligand) and [Re(CO)3(C^N^C)](+)[X](-) (where C^N^C is a bis(NHC)-amine ligand and the counter ion X is either the ReO4(-) or PF6(-)) have been synthesised using a Ag2O transmetallation proto...
NaRe$_2$(PO$_4$)$_3$ phosphate-based ceramic with the structure of kosnarite mineral was obtained by spark plasma sintering. Rhenium (Re) served as a chemical and structural analog technetium. The relative density 85%. mechanism Re static leaching from at room temperature investigated. rate rhenium $1.3\times10^{-5}$ g/(cm$^2$*day).
Intra-arterial metabolic radiotherapy (using lipiodol labelled with iodine-131 or rhenium-188) is a therapeutic approach that can be used for the treatment of hepatocellular carcinomas (HCC). We propose a detailed description of the tumoral model using the N1-S1 cell line as well as a technique for intra-arterial injection of radiolabelled lipiodol in order to undertake preclinical studies nece...
There is an increasing interest in irradiation to control restenosis after balloon angioplasty by an internal radioactive source. Differences in radiosensitivity of the predominant cells of the human coronary artery (i.e. endothelial cells (HCAEC), smooth muscle cells from the media (HCMSMC) and from plaque material (HCPSMC), are issues of controversal discussion. Therefore, we investigated the...
A thermal stress range analysis of tungsten-rhenium thin film thermocouples based on ceramic substrates is presented to analyze the falling off and breakage problems caused by the mismatch of the thermal stresses in thin film thermocouples (TFTCs) and substrate, and nano-indentation experiments are done to measure and calculate the film stress to compare with the simulation results. Optimal des...
Selective dissolution of a tungsten (85 wt.%)–rhenium (15 wt.%) alloy with rhenium in hydrochloric acid at the temperature 298 K and anodic polarization modes was carried out to develop porous catalytic substrate recycle rare metals. The parameters effective selective tungsten–rhenium alloy, including differences applied potentials electrolyte composition, were found. It established that sample...
