the purpose of this study was to produce oil in water nano-emulsion by ultrasonication, and investigate the influence of inulin and β-cyclodextrin on the prosperities of nano-emulsion and morphology of spray dried microcapsules. the results showed that emulsion droplet size in samples containing β-cyclodextrin (8.28±0.11 nm) was less than inulin samples (97.12±4.2 nm). considering sem photos, β...
More than 4.5 billion people worldwide are affected by parasitic diseases, with helminth infections accounting for 99% of the total number. Niclosamide (NS) is a weakly acidic active pharmaceutical ingredient (API) used to treat infections. However, use pure niclosamide limited its low bioavailability due poor aqueous solubility. The aim this work mechanochemical preparation solid dispersions i...
فاضلاب واحدهای چاپ و رنگرزی در صنایع نساجی اغلب حاوی رنگ و مواد شیمیایی هستند. یکی از رنگ¬های مورد استفاده در این صنعت، رنگ آلیزارین زرد می¬باشد که دارای ترکیبات معطر، هتروسیکلیک، بسیار پایدار بوده و باعث سخت شدن فرآیند حذف رنگ از فاضلاب می¬شوند. در این تحقیق، جاذب¬های h5pv2w10o4 (hp)، hp+co و hp+co+k ساخته شد. جذب رنگ آلیزارین زرد بوسیله جاذب¬های hp، hp+co و hp+co+k توسط فرآیند جذب سطحی بررسی ...
While unesterified cholesterol (C) is essential for remodeling neuronal plasma membranes, its role in certain neurodegenerative disorders remains poorly defined. Uptake of sterol from pericellular fluid requires processing that involves two lysosomal proteins, lysosomal acid lipase, which hydrolyzes C esters, and NPC1 (Niemann-Pick type C1). In systemic tissues, inactivation of either protein l...
b-cyclodextrin glucosyl transferase (b-cgtase) hydrolyses starch to produce b-cyclodextrin by transglycosylation (cyclization) activity. the conventional method for detection of b-cgtase activity is based on detecting starch hydrolysis by iodine staining. this method reveals all amylolytic enzymes, but can not discriminate them. in the present study, we introduce a new method for specific detec...
Meclizine HCl is a poorly water-soluble drug having a very slow-onset of action. The effect of 2-hydroxypropyl-β-cyclodextrins and β-cyclodextrins on its aqueous solubility and dissolution rate was investigated. The phase solubility profile indicated that the solubility of Meclizine HCl was significantly increased in the presence of both 2-hydroxypropyl-β-cyclodextrin and β- cyclodextrin; an ex...
