Functional and ultrastructural studies of liposomes injected i.v. into inbred C57BL/6N mice were performed to determine whether free liposomes can traverse capillaries. In the liver and spleen, organs with discontinuous (sinusoidal) capillaries, ultrastructural and cell fractionation studies revealed that small (300- to 800-A diameter), sonicated, unilamellar liposomes were more efficient in pe...
Intravenously administered liposomes are versatile carriers for drugs, contrast agents, biologics, and DNA. Liposomes and other colloidal particles are currently under investigation as lymph node delivery vehicles. After s.c. injection, conventional liposomes move into the lymphatic vessels, but are poorly retained in each draining lymph node (<2% injected dose). In this report, we describe a n...
Maleimide is a stable and easy-to-handle moiety that rapidly and covalently conjugates thiol groups of cysteine residues in proteins or peptides. Herein, we use maleimide to modify the surface of liposomes in order to obtain an advanced drug delivery system. Employing a small amount (0.3 mol%) of maleimide-polyethylene glycol (PEG) to modify the surface of the liposomes M-GGLG-liposomes, compos...
objective:platycladus orientalis or thuja orientalis is a native plant of iran different parts of which are used in the treatment of various diseases such as: gout, rheumatoid arthritis, common cold, cough, bronchitis, asthma, high blood pressure and hormonal disorders like hirsutism and baldness. also, various organs of this species have been used as appetizer. the purpose of this study was to...
Purpose: In this study, cytotoxicity and whitening effects of liposomes non-liposomes containing Geranium maculatum (G. maculatum) were measured to confirm their functionality as a cosmetic material.Methods: The test was used measure the effect G. in on B16F10 cells, performed inhibitory melanin tyrosinase production. Furthermore, LPS-induced NO production determined RAW 264.7 cells. Cell viabi...
Viruses are known to hijack the intracellular organelles, including mitochondria, endoplasmic reticulum, lipid droplets, and cytoskeleton promote its replication. The host responds invading viruses by mounting antiviral responses rearrangement of organelles. In particular, mitochondria one target organelles exploited their proteins suppress response. this review, we have comprehensively summari...
This investigation determined the organ distribution of liposomes containing egg phosphatidylcholine and cholesterol with egg phosphatidylglycerol (PG liposomes) or without (PC liposomes) and the effect of each liposome on platelet distribution in rabbits. Eight minutes after 51chromium-labelled platelets were given intravenously, either saline (n = 7), iodinated PG liposomes (n = 5) or iodinat...
In this study, long-circulating Arg-Gly-Asp (RGD)-modified aclacinomycin A (ACM) liposomes were prepared by thin film hydration method. Their morphology, particle size, encapsulation efficiency, and in vitro release were investigated. The RGD-ACM liposomes was about 160 nm in size and had the visual appearance of a yellowish suspension. The zeta potential was -22.2 mV and the encapsulation effi...
Liposomes (lipid vesicles) are often considered to be a versatile tool for the synthesis of advanced materials, as they allow various control mechanisms tune materials’ properties. Among diverse calcium phosphates (CaPs) and carbonates (CaCO3) using liposomes has attracted particular attention in development novel (bio)materials biomineralization research. However, preparation materials not yet...
Liposomes are nanocarriers consisting of a phospholipid bilayer, similar in composition and structure to cell membrane. Such feature provides several possibilities related the transport delivery biologically active substances specific cells organisms. It is now becoming more popular modify lipid carrier shells achieve higher specificity efficiency into cells, reduce immunogenicity. The article ...
