Gel-Assisted Formation of Giant Unilamellar Vesicles [PDF]
Biophysical Journal, 2013 Giant unilamellar vesicles or GUVs are systems of choice as biomimetic models of cellular membranes. Although a variety of procedures exist for making single walled vesicles of tens of microns in size, the range of lipid compositions that can be used to grow GUVs by the conventional methods is quite limited, and many of the available methods involve ...

Bulk Self-Assembly of Giant, Unilamellar Vesicles
ACS Nano, 2020 The desire to create cell-like models for fundamental science and applications has spurred extensive effort towards creating giant unilamellar vesicles (GUVs). However, a route to selectively self-assemble GUVs in bulk has remained elusive. In bulk solution, membrane-forming molecules such as phospholipids, single-tailed surfactants, and block ...

Electric Fields and Giant Vesicles [PDF]
Biophysical Journal, 2010 Electric fields are omnipresent in our world, and are relevant not only from a physics point of view. Indeed, they also play a crucial role in several biological mechanisms occurring in living organisms, and they can turn out to be useful and easy-to-use tools to alter or to measure various biomaterials properties [1].Provided they have the appropriate

The giant seminal vesicle cyst: MRI findings.
Journal of the Belgian Society of Radiology, 2012 A 73-year-old man suffering from supra-pubic pain, dysuria and urinary retention for 3 months was slightly hypertensive, normoglycaemic, with normal renal biochemical parameters.

Bio-Protocol, 2022 Transbilayer movement of phospholipids in biological membranes is mediated by a diverse set of lipid transporters. Among them are scramblases that facilitate rapid bi-directional movement of lipids without metabolic energy input.

Membranes, 2022 Yeast S. cerevisiae has been shown to suppress a sterol biosynthesis as a response to hyperosmotic stress. In the case of sodium stress, the failure to suppress biosynthesis leads to an increase in cytosolic sodium. The major yeast sterol, ergosterol, is

Giant vesicles under oxidative stress [PDF]
Biophysical Journal, 2009 We use optical microscopy to observe giant unilamellar vesicles (GUVs) during the initial steps of membrane oxidative damage. A photo-sensitive molecule consisting of a porphyrine linked to a lipid headgroup (PE-porf) is incorporated in the lipid bilayer, thus generating singlet oxygen at the bilayer surface.
