Solid dispersions (SDs) of ursolic acid (UA) were developed using polyvinylpyrrolidone K30 (PVP K30) in combination with non-ionic surfactants, such as D-α-tocopherol polyethylene glycol 1000 succinate (TPGS) or poloxamer 407 (P407) the aim enhancing solubility and vitro release UA. SDs investigated a 24 full factorial design, subsequently selected formulations characterized for water solubilit...

In this work attempts were made to evaluate K+-SDS and hydrocolloid polymer-SDS interactions in flocculation of megestrol acetate dispersions to enhancetheir stability as a part of suspension formulation. Different dispersions of micronized megestrol acetate and SDS were prepared. KCl and KH2PO4 and their corresponding sodium salts were added to the dispersions and the preparations were evaluat...

Initial characteristics of emulsions would lead to different structures during drying of emulsion-based films, which in turn will affect the behavior of the film. The objective of this work was to study the effect of oil concentration and the use of surfactant over bubble sizes, interfacial tension, rheological properties and stability of oil-in-water emulsions stabilized by hydroxypropyl methy...

Fractional flow analysis confirms the advantages of surfactant alternative gas injection (SAG) in enhanced oil recovery, but an adsorption phenomenon that has been affected by several factors, weakens the effectiveness of SAG injection. In this study, the effects of sacrificial agent, gas phase, and surfactant concentration on adsorption density on silica mineral were investigated by static and...

長年,アレルゲンの解析手法としてSDS-PAGEとWestern blottingが用いられてきた.この場合,タンパク質をできるだけ可溶化するために,SDSなどの変性剤を高濃度で添加することが多い.筆者らはこの手法を用いて,甲殻類アレルゲンの種特異的反応性の違いを検出した.ところが,別の患者血清では,この方法ではバンドが全く検出されなかった.そこでこの患者血清をdot blottingで調べたところ,生では強く反応したが,80°Cで15分加熱すると反応が失われた.そこで,生の試料をdot blotしたPVDF膜を0.1%SDSを含む電気泳動バッファー中で1時間インキュベートしたところ反応性は弱まったが,完全には反応が消失していなかった.そこで,0.1%SDSを含むSDS抽出液を用いてSDS-PAGEを行ったところ,トロポミオシンのバンドが弱く反応した.甲殻類アレルゲンのSDS変性を低...
