Abstract:
A hybrid bioreactor for cell culture is disclosed. To simultaneously apply compressive strain for cell differentiation and shear strain for cell proliferation to cells, the hybrid bioreactor includes a plurality of reactor tube assemblies (100), a compressive strain motor (5), a shear strain motor (25), a lower anchor mount (20) having a plurality of toothed anchors (70) to respectively anchor the lower ends of the reactor tube assemblies (100) to the lower anchor mount (20), a ball screw (90) operated in conjunction with the compressive strain motor (5), an upper anchor mount (60) which engages with the ball screw (90) to vertically move upward and downward and having a plurality of compressive strain anchors (80) to anchor the upper ends of the reactor tube assemblies (100) to the upper anchor mount (60), a power transmission unit to transmit the rotating force of the shear strain motor (25) to the toothed anchors (70).
Abstract:
The present invention relates to a paclitaxel composition and the preparation methods thereof to solubilize paclitaxel wherein said composition comprises 4~90% by weight of at least one selected from the monoglycerides, 0.01~90% by weight of at least one oil and 0.01~20% by weight of paclitaxel. Also the present invention relates to a paclitaxel composition including emulsifiers and the preparation methods thereof to solubilize paclitaxel wherein said composition comprises 4~90% by weight of at least one selected from the monoglycerides, 0.01~90% by weight of at least one oil, 0.01~90% by weight of at least one emulsifier and 0.01~20% by weight of paclitaxel. The composition of the present invention is an effective paclitaxel delivery system since the composition solubilizes paclitaxel, does not form aggregates after being dispersed in water, adsorbs well on the intestinal wall, and therefore has high bioavailability.
Abstract:
The present invention relates to a liquid insulin formulation and the preparation method thereof. More particularly, the present invention relates to a liquid and powder formulations comprising a monoglyceride, an emulsifier, organic solvent, insulin and acidic aqueous solution. The present invention relates to the liquid and powder insulin formulations with a higher encapsulation efficiency of insulin, higher bioavailability upon oral administration with higher patient compliance and the preparation method thereof.
