The aim of this study was to prepare micronized taxifolin powder using the supercritical antisolvent precipitation process to improve the dissolution rate of taxifolin. Ethanol was used as solvent and carbon dioxide was used as an antisolvent. The effects of process parameters, such as temperature (35-65 °C), pressure (10-25 MPa), solution flow rate (3-6 mL/min) and concentration of the liquid ...
The goal of the present work was to study the feasibility of 10-hydroxycamptothecin (HCPT) nanoparticle preparation using supercritical antisolvent (SAS) precipitation. The influences of various experimental factors on the mean particle size (MPS) of HCPT nanoparticles were investigated. The optimum micronization conditions are determined as follows: HCPT solution concentration 0.5 mg/mL, the f...
The purpose of this investigation was to determine whether shellac, a naturally occurring material with enteric properties, could be processed in supercritical CO2 (sc-CO2) using the particles from gas saturated solution (PGSS) process and how process parameters affect the physico-chemical properties of shellac. In-situ attenuated total reflection fourier transform infra-red (ATR-FTIR) spectros...
The aim of the present work is to emphasize about the importance and to make a capsule review on self micro emulsifying drug delivery system. Oral route of drug administration has been the most prominent way of drug delivery system, because of its ability to prepare the formulation in an economical way, easy to administer, does not require any specific storage condition compared with parenteral...
با توجه به شیوع سرطان در جوامع امروزی، یافتن داروهای جدید برای درمان آن از اهمیت بالایی برخوردار است. استفاده از داروهای شیمیایی موجود به دلیل عوارض جانبی که دارند با محدودیت مصرف روبه رو می باشند. از این رو محققین درصدد یافتن مواد طبیعی با خاصیت ضد سرطانی می باشند. هدف اصلی این پایان نامه بررسی اثرات ضد سرطانی lactoferrin وwhey acidic protein موجود در شیر شتر می باشد. در تحقیق حاضر تأثیر lacto...
The high need for polymeric materials and the availability of agro-industrial wastes, such as rice production chain, demand development technologies to obtain composites based on these waste materials. Therefore, this work aims develop using low density polyethylene (LDPE) a polymer matrix husk or ash, prepared by micronization in whirlwind mill, reinforcing fillers. processing was carried out ...
