Easy and Fast Preparation of Large and Giant Vesicles from Highly Confined Thin Lipid Films Deposited at the Air–Water Interface
(Springer New York LLC, 2018-03-31)
Lipid vesicles are supramolecular structures of great interest for industrial and research applications. They can be used simply to compartmentalize solutions and pack active molecules in femtoliter-scale volumes or as ...
Cholesterol modulates curcumin partitioning and membrane effects
(2018-01-01)
Curcumin, a polyphenol molecule, presents a wide range of biological activities as antioxidant, anticancer, anti-inflammatory, antimicrobial and wound healing. Although some strengths attributed to curcumin derive from ...
Photo-activated phase separation in giant vesicles made from different lipid mixtures
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
Using giant unilamellar vesicles (GUVs) made from POPC. DPPC, cholesterol and a small amount of a porphyrin-based photosensitizer that we name PE-porph, we investigated the response of the lipid bilayer under visible light, ...
Role of Rab27 in synaptic transmission at the squid giant synapse
(NATL ACAD SCIENCES, 2008)
Small GTPase Rab is a member of a large family of Ras-related proteins, highly conserved in eukaryotic cells, and thought to regulate specific type(s) and/or specific step(s) in intracellular membrane trafficking. Given ...
Ultrastructure and histochemistry of the digestive gland of the giant predator snail Adelomelon beckii (Caenogastropoda: Volutidae) from the SW Atlantic
(Elsevier, 2015-04)
This study deals with the structure of the digestive gland of the carnivorous gastropod Adelomelon beckiiin Mar del Plata area (Argentina) and discusses the function of its cell types and compare with othergastropods. ...
Primary Giant Splenic Echinococcal Cyst Treated by Laparoscopy
(American Society of Tropical Medicine and Hygiene, 2016)
Cystic echinococcosis (CE) is a zoonosis caused by the larval stage of the dog tapeworm Echinococcus granulosus. Liver and lungs are the most commonly affected organs whereas splenic infection is rarer and its primary ...
Phosphatidylserine lipids and membrane order precisely regulate the activity of Polybia-MP1 peptide
(2017-06-01)
Polybia-MP1 (IDWKKLLDAAKQIL-NH2) is a lytic peptide from the Brazilian wasp venom with known anti-cancer properties. Previous evidence indicates that phosphatidylserine (PS) lipids are relevant for the lytic activity of ...
Efeito do pH e da composição lipídica na interação do peptídeo antimicrobiano MP1 e seu análogo H-MP1 com membranas modelo
(Universidade Estadual Paulista (Unesp), 2019-05-20)
Peptídeos líticos com propriedades antimicrobianas são catiônicos e atuam na membrana celular desestabilizando o empacotamento lipídico levando a célula à lise. Polybia-MP1 ou MP1 (IDWKKLLDAAKQIL-NH2) é um potente bactericida, ...
Effect of Triton X-100 on Raft-Like Lipid Mixtures: Phase Separation and Selective Solubilization
(Amer Chemical Soc, 2017)
Under certain conditions, biological membranes exhibit resistance to solubilization, even at high detergent concentration. These insoluble fragments are enriched in sphingolipids, cholesterol, and certain proteins having ...
Direct Visualization Of The Action Of Triton X-100 On Giant Vesicles Of Erythrocyte Membrane Lipids
(Biophysical Society, 2014)
