 Context examples 


The researchers have used exosomes as “Trojan horses” to deliver palladium (Pd) catalysts into cancer cells.

When used to treat prostate cancer, radioactive seeds (small pellets that contain radioactive palladium) are placed in the prostate.

(Palladium Pd-103, NCI Dictionary)

A radioisotope of the metal palladium used in brachytherapy implants or 'seed'.

(Palladium Pd-103, NCI Thesaurus)

Upon oral administration, the alpha-lipoic acid-palladium/vitamin/mineral supplement acts as a free radical scavenger, crosses the cell membrane and is able to transfer electrons from fatty acids to DNA via the electron transport chain in mitochondria, which protects against DNA damage.

(Alpha-lipoic Acid-Palladium/Vitamin/Mineral Supplement, NCI Thesaurus)

With a half-life of 17 days, palladium 103 administered with brachytherapy allows continuous, tumor-site specific low-energy irradiation to the tumor cell population while sparing normal adjacent tissues from radiotoxicity.

(Palladium Pd-103, NCI Thesaurus)

A radioactive form of palladium (a metallic element that resembles platinum).

(Palladium Pd-103, NCI Dictionary)

A proprietary water- and lipid-soluble polymer-based nutritional supplement composed of a complex mixture of alpha-lipoic acid bound to palladium (Palladium Lipoic Acid Complex (PdLA)) and other minerals, vitamins and amino acids, including vitamins B1, B2 and B12, formylmethionine, acetyl cysteine, and trace amounts of molybdinum, rhodium, and ruthenium, with potential anti-oxidant and cytoprotective activities.

(Alpha-lipoic Acid-Palladium/Vitamin/Mineral Supplement, NCI Thesaurus)

Having demonstrated the effectiveness of this process in their study, the researchers observe: “We collected exosomes of the same type of cancerous cell that was to be treated, we loaded them with the palladium catalyst and returned them to the culture medium. There, thanks to their selective tropism, the exosomes deliver the catalyst to the original cell.
