The present invention provides: an adhesive composition comprising an isobutylene-based polymer (A), a diene-based rubber (B) that includes a hydroxyl group, and a crosslinking agent (C); an adhesive sheet comprising an adhesive layer that is formed using the adhesive composition; and an electr...
An intravaginal drug delivery device according to the present invention was prepared by blending 100 parts by weight of a hydrophobic elastomeric polymer (polydimethylsiloxane) containing about 25% w/w diatomaceous earth as the filler, with 2.5 parts by weight of a cross-linking agent, n-propylort...
The action mechanism thereof is thought to be based on inhibition of DNA synthesis or protein synthesis via cross-linking with DNA bases, similar to precedent platinum-based complex anti-cancer agents such as cisplatin (CDDP) and carboplatin (CBDCA). However, oxaliplatin (L-OHP) exhibits an ...
