Large unilamellar liposomes with low uptake into the reticuloendothelial system
FEBS Letters, 1987 Particulate drug carriers, including liposomes, are rapidly removed from blood by cells of the reticuloendothelial system (RES) with resulting adverse effects on this important host defense system. In order to overcome this and other major disadvantages of liposomes, we have altered liposome composition in an effort to achieve prolonged circulation ...

Functionalization and higher-order organization of liposomes with DNA nanostructures
Nature Communications, 2023 Small unilamellar vesicles (SUVs) are indispensable model membranes, organelle mimics, and drug and vaccine carriers. However, the lack of robust techniques to functionalize or organize preformed SUVs limits their applications.

Effect of ultrasound parameters for unilamellar liposome preparation [PDF]
Ultrasonics Sonochemistry, 2010 In this study, it was investigated the effects of ultrasound, namely power input, distance from ultrasound tip to base of reactor and treatment time, in the formation of liposomes. Results indicate a dependence on cavitation events that are a function of power input, and consequently dependent on the position of the probe within the reaction vessel and

Tailoring the Lamellarity of Liposomes Prepared by Dual Centrifugation
Pharmaceutics, 2023 Dual centrifugation (DC) is a new and versatile technique for the preparation of liposomes by in-vial homogenization of lipid-water mixtures. Size, size distribution, and entrapping efficiencies are strongly dependent on the lipid concentration during DC-

Ultraviolet A-Induced Peroxidation of Phosphatidylcholine in Unilamellar Liposomes [PDF]
Bioscience, Biotechnology, and Biochemistry, 2009 Unilamellar liposomes of 1-palmitoyl-2-linoleoyl-3-sn-phosphatidylcholine (PLPC) were exposed to ultraviolet A (UVA) light at 37 degrees C. The UVA-induced PLPC peroxidation was inhibited by free radical scavengers, while singlet oxygen quenchers showed slight inhibition. When pre-existing hydroperoxides were reduced, UVA irradiation could not initiate

Using small molecules to facilitate exchange of bicarbonate and chloride anions across liposomal membranes [PDF]
, 2009 Bicarbonate is involved in a wide range of biological processes, which include respiration, regulation of intracellular pH and fertilization. In this study we use a combination of NMR spectroscopy and ion-selective electrode techniques to show that the ...

Encapsulation of ropivacaine in a combined (donor-acceptor, ionic-gradient) liposomal system promotes extended anesthesia time. [PDF]
PLoS ONE, 2017 Ropivacaine is a local anesthetic with similar potency but lower systemic toxicity than bupivacaine, the most commonly used spinal anesthetic. The present study concerns the development of a combined drug delivery system for ropivacaine, comprised of two
