PURPOSE Evaluation of doxorubicin stability over time when stored into the DC Bead embolic agent, in various containers, which are used for the delivery of the doxorubicin-loaded beads to the patients for up to 14 days under refrigerated conditions. METHODS The doxorubicin was loaded through the ionic exchange mechanism into the calibrated polyvinyl alcohol-based hydrogel beads (DC Bead), wit...

Attempts have been made to optimize immobilization parameters, catalytic property, and stability of immobilized α-amylase in agar. The work compares natural entrapment efficiency of agar with the ionotropically cross-linked agar hydrogel, with the advantage of easy scale-up and cost and time effectiveness. Beads prepared with 3% (w/v) agar and 75 mM calcium chloride and hardened for 20 minutes ...

A new hydrogel beads-sponge structure (these beads combine the properties of with sponge character) a super rate swelling in water and wastewater large porosity was created during this research. New biosorbents were obtained by modification three parts Moringa oleifera (seeds, leaves husks). Prepared adsorbent characterised some analytical methods, viz. FT-IR, SEM SEM-EDX. The effects operation...

Microencapsulation has become a common technique in the production of controlled release dosage forms. Many results have been reported, concerning the use of alginate beads as controlled release drug formulations. Alginate has a unique gel-forming property in the presence of multivalent cations, in an aqueous medium. Ibuprofen is an excellent analgesic and antipyretic, non-steroidal anti-inflam...

• Anion species-triggered antibody separation under optimized constant temperature. species-responsive retention of antibodies by thermo-resopnsive polymer column. Successful therapeutic monoclonal from contaminants. Although the field drugs has grown larger, production still faces several challenges. Effective purification is required, but conventional method for cost intensive and often cause...
