[ 3 ] - Development and Validation of HPLC Method for Determination of Crocetin, a constituent of Saffron, in Human Serum Samples
Objective(s):The present study reports the development and validation of a sensitive and rapid extraction method beside high performance liquid chromatographic method for the determination of crocetin in human serum. Materials and Methods:The HPLC method was carried out by using a C18 reversed-phase column and a mobile phase composed of methanol/water/acetic acid (85:14.5:0.5 v/v/v) at the flow...
[ 4 ] - The Effect of Linear PEI on Characteristics and Transfection Efficiency of PEI-Based Cationic Nanoliposomes
The development of efficient and safe carrier system to transfer DNA into cells is essential in non-viral gene therapy. The aim of the present study was to evaluate the effect of linear polyetheneimine (lPEI) (2500 Da) on the physicochemical and biological properties of lipopolyplexes constructed from liposomes and lPEI. Materials and Methods Different lipopolymers were synthesized from lPEI ...
[ 5 ] - Nanoencapsulation and delivery of curcumin using some carbohydrate based systems: A review
Nanoencapsulation is commonly used to improve nutritional properties, rheological behavior and flavor profile of phytochemicals. The particles commonly utilized to encapsulate the functional ingredients are natural polymers such as polysaccharides and proteins. There is an ever-growing interest for use of polysaccharides to encapsulate hydrophobic phytochemicals like curcumin. Curcumin is a pol...
[ 6 ] - The effect of mesoporous silica nanoparticles loaded with epirubicin on drug-resistant cancer cells
Objective (s): In chemotherapy for cancer treatment, the cell resistance to multiple anticancer drugs is the major clinical problem. In the present study, mesoporous silica nanoparticles (MSNs) were used as a carrier for epirubicin (EPI) in order to improve the cytotoxic efficacy of this drug against the P-glycoprotein (P-gp) overexpressing cell line. Materials and Methods: MSNs with phosphonat...
[ 7 ] - Preparation, characterization and transfection efficiency of nanoparticles composed of alkane-modified polyallylamine
Objective(s): Although viral vectors are considered efficient gene transfer agents, their board application has been limited by toxicity, immunogenicity, mutagenicity and small gene carrying capacity. Non-viral vectors are safe but they suffer from low transfection efficiency. In the present study, polyallylamine (PAA) in two molecular weights (15 and 65 kDa) was modified by alkane derivatives ...
[ 8 ] - Evaluation of cyclosporine A eye penetration after administration of liposomal or conventional forms in animal model
A lot of researches have investigated the effects of topical cyclosporine A on the eye surface layers’ diseases. By now the main limitation in cyclosporine application is the low permeation of the drug into the posterior segments of the eye. The aim of present study was to formulate high permeable dosage form can be beneficial in the topical treatment of the uveitis. To reach higher corneal dru...
[ 9 ] - تهیه قطره چشمی تاکرولیموس با استفاده از سیکلودکسترین ها
Background and Aim: Application of topical tacrolimus in Vernal Keratoconjunctivitis is considered as an alternative to steroids. Due to the low aqueous solubility of the drug, preparing a solution of the drug has got particular importance. In the present study, tacrolimus eye drop was prepared using cyclodextrin, as a drug solubility enhancer. Materials and Methods: To improve the aqueous s...
[ 10 ] - بررسی نانوکمپلکس آلبومین سرم گاوی-کورکومین به روش طیف‌سنجی فلوئورتابی
یکی از مهم‌ترین عملکردهای زیستی آلبومین، توانایی پیوند با ترکیبات زیست‌فعال طبیعی و سنتزی است. لذا آلبومین به‌عنوان حامل، برای پیوند با موادی مانند ترکیبات گیاهی با ویژگی‌های درمانی و دارویی گزینه مناسبی به نظر می‌رسد. از سوی دیگر پیشرفت‌های اخیر در زمینه علم نانو و انتقال غذا داروها، مستلزم پژوهش‌های گسترده در زمینه تهیه و بررسی ساختار نانوکمپلکس مواد زیست فعال است. در این مطالعه، برهم‌کنش آلب...
[ 11 ] - Curcumin improved liposomal mitomycin-induced cell toxicity in bladder cancer cell
Objective (s): This study aimed at investigation of preparation and stability study of Mitomycin and Mitomycin loaded nanoliposems and efficacy of the combination of Mitomycin -loaded nanoliposomes and Curcumin versus Mitomycin in suppressing HTB-9 and L929 cell lines, in vitro.Materials and Methods: An HPLC method was validated based on Q2 (R1) International Conference on Harmonization (ICH) g...
[ 14 ] - Effect of the nanoliposomal formulations of rifampin and N-acetyl cysteine on staphylococcus epidermidis biofilm
Objective(s): Staphylococcus epidermidis is a common cause of medical device-associated infections due to biofilm formation, and its elimination is extremely challenging. Although rifampin efficacy against S. epidermidis biofilms has been confirmed, its use as a single agent may lead to resistance. As such, it is assumed that the combination of rifampin and N-acetylcysteine (NAC) could exert ad...
[ 15 ] - Application of mesoporous silica nanoparticles for drug delivery to cancer cells
Cancer is one of the main causes of death worldwide. Chemotherapy is the most common method for cancer therapy which represent non-specific side effects on normal cells and tissues and drug resistance in cancer cells. There are two main mechanisms for Multi Drug Resistance (MDR) in cancer cells including: drug efflux pump and activation of anti-apoptotic pathways. Cancer chemotherapy disadvanta...
