Span 80 (sorbitan monooleate) vesicles behaved differently from conventional phospholipid vesicles (liposomes) because the former had a more fluid interface. After doxorubicin hydrochloride (DOX) was encapsulated into the Span 80 vesicle (loading efficiency: 63 %), DOX-loaded Span 80 vesicles (DVs) were thereafter added to Colon 26 cells. It was suggested, from the flow cytometric analysis and ...

Simultaneous encapsulation of multiple active substances in a single carrier is essential for therapeutic applications of synergistic combinations of drugs. However, traditional carrier systems often lack efficient encapsulation and release of incorporated substances, particularly when combinations of drugs must be released in concentrations of a prescribed ratio. We present a novel biodegradab...

BACKGROUND Given the importance of complementary and alternative medicine (CAM) to cancer patients, there is an increasing need to learn more about possible interactions between CAM and anticancer drugs. Mistletoe (Viscum album L.) belongs to the medicinal herbs that are used as supportive care during chemotherapy. In the in vitro study presented here the effect of standardized mistletoe prepar...

Through the high affinity of the β-cyclodextrin (β-CD) cavity for adamantane moieties, novel polysaccharide-gold nanocluster supramolecular conjugates (HACD-AuNPs) were successfully constructed from gold nanoparticles (AuNPs) bearing adamantane moieties and cyclodextrin-grafted hyaluronic acid (HACD). Due to their porous structure, the supramolecular conjugates could serve as a versatile and bi...

A new approach of fabricating supramolecular nanoparticles generated by self-assembly polyrotaxanes for antitumor drug delivery has been reported. Cinnamic-acid-modified poly(ethylene glycol) chains were threaded in α-cyclodextrins to form polyrotaxanes. The polyrotaxanes self-assembled supramolecular nanoparticles. The morphology of the nanoparticles was changed from nanovesicle to micelle aft...

OBJECTIVE To investigate a new chemotherapeutic regimen as an adjunct to the conventional surgical management of patients with advanced adenocystic carcinoma of the lacrimal gland. PATIENTS AND METHODS Two patients with extensive adenocystic carcinoma of the lacrimal gland were treated with intracarotid cisplatin and intravenous doxorubicin hydrochloride prior to orbital exenteration. Postope...

buprenorphine is a partial mu agonist and kappa antagonist which is used for the treatment of pain and opioid addiction. a mixture of buprenorphine hydrochloride and naloxone hydrochloride has been approved for the treatment of opioid dependence.in this study a third order derivative spectrophotometric method based on zero-crossing technique has been used for the simultaneous determination of b...
