Liposomes are artificially prepared vesicles consisting of natural and synthetic phospholipids that are widely used as a cell membrane mimicking platform to study protein-protein and protein-lipid interactions, monitor drug delivery, and encapsulation. Phospholipids naturally create curved lipid bilayers, distinguishing itself from a micelle. Liposomes are traditionally classified by size and n...

Liposomes are sphere-shaped vesicles made up of one or more bilayers phospholipids. The ability delayed to transport medications, vaccines, diagnostic specialists, and other bioactive operators has accelerated development in the liposomal drug delivery system. system's pharmacyelements pharmacokinetics properties have been altered, resulting a higher therapeutic index lower overall toxicity. Th...

We investigated flexible liposomes as a potential oral drug delivery system. However, enhanced membrane fluidity and structural deformability may necessitate liposomal surface modification when facing the harsh environment of the gastrointestinal tract. In the present study, silica-coated flexible liposomes loaded with curcumin (CUR-SLs) having poor water solubility as a model drug were prepare...

Natural food pigments are commonly utilized for the improvement of the qualitative properties of foods and/or inhibit the development of chronic and degenerative diseases. Several studies have documented the beneficial health effects of natural food pigments, such as anthocyanins, chlorophylls, and carotenoids. These effects mainly depend on the stability, bioactivity, and bioavailability of th...

Emodin is a multifunctional Chinese traditional medicine with poor water solubility. D-α-tocopheryl polyethylene glycol 1000 succinate (TPGS) is a pegylated vitamin E derivate. In this study, a novel liposomal-emodin-conjugating TPGS was formulated and compared with methoxypolyethyleneglycol 2000-derivatized distearoyl-phosphatidylethanolamine (mPEG2000-DSPE) liposomal emodin. TPGS improved the...

objective: this study aimed to evaluate a co-encapsulated pegylated nano-liposome system based on two herbal anti-tumor drugs, silibinin and glycyrrhizic acid, for delivery to a hepatocellular carcinoma (hcc) cell line (hepg2). materials and methods: in this experimental study, co-encapsulated nano-liposomes by the thin layer film hydration method with hepes buffer and sonication at 60% amplitu...

OBJECTIVE To discuss the influences of the concentrations of sodium cholate, cholesterol and drug, preparation temperature, ultrasonic time and power on the particle size and encapsulation efficiency of Flos Magnoliae volatile oil nano-liposome through film-ultrasonic wave technique together with membrane filter method. METHODS The nano-liposomes were prepared by film-ultrasonic wave techniqu...

Nanoliposomes are drug release systems that increase bioavailability and used for encapsulation of therapeutic active ingredients. Terebinth, which is a medicinal plant grows in many parts Türkiye, has antibacterial, antioxidant, anti-inflammatory activity. The antibacterial activity nanoliposomes incorporated with ethanol extract terebinth leaves (TLE) was investigated to determine the effects...

Cholesterol plays a critical role in liposome composition. It has great impact on the behavior of liposome in vitro and in vivo. In order to verify the possible effects from cholesterol charge, surface shielding and chemical nature, two catalogs of liposomes with charged and PEGylated cholesterols were synthesized. Anionic liposomes (AL) and cationic liposomes (CL) were prepared, with charges f...

Nuclear factor erythroid 2-related factor 2 (Nrf2) has been recognized as a transcription factor that controls mechanisms of cellular defense response by regulation of three classes of genes, including endogenous antioxidants, phase II detoxifying enzymes and transporters. Previous studies have revealed roles of Nrf2 in resistance to chemotherapeutic agents and high level expression of Nrf2 has...
