Phase separation in giant vesicles
Giant vesicles may contain several spatial compartments formed by phase separation within their enclosed aqueous solution. This phenomenon might be related to molecular crowding, fractionation and protein sorting in cells. To elucidate this process we used two chemically dissimilar polymers, …

Engineered Vesicles for Perchlorate Degradation
This study demonstrates the use of engineered vesicles to reduce perchlorate. Specifically, cell-free extracts containing perchlorate reductase and chlorite dismutase enzymes were encapsulated in a triblock copolymer vesicle functionalized with the outer membrane porin OmpF. The porin allows for …

Microfluidic Transport Studies on Lipid Vesicles
… Assembly (OLA) technique to obtain lipid vesicles which serve as model membrane for our studies. We perform a literature review, where we discuss OLA and other techniques to obtain liposomes in detail, before we provide a biophysical analysis of liposomes generated with OLA and compare …

Giant vesicles compressed by actin polymerization
… mechanical properties of synthetic Giant Vesicles with the well understood biochemistry of actin polymerization. Giant Vesicles mimic the structural features of eukaryotic cell membranes. We find that Giant Vesicles coated with a protein that catalyzes actin polymerization form thick actin …

Resistive Pulse study of Vesicles and Liposomes
… of the liposomes, the artificially created vesicles by various methods, are explored by a resistive pulse method using micropipettes. The fact that vesicles are fundamental in the wide range of functionalities they fulfill as organelles strengthen the desire of understanding the properties …

Plasma membrane-derived vesicles: composition and function
Plasma membrane-derived vesicles (PMVs) are small, intact, membrane vesicles, which are released by most cells upon activation with various extracellular stimuli. This study identified that procedures used in the isolation of PMVs could be further improved by first sonicating (sonicating …

Characterizing Oxylipins in Human Milk Extracellular Vesicles
<p>Extracellular vesicles (EVs) are non-replicating lipid bilayer membrane-bound particle formed by a parent cell and secreted into the extracellular environment. EVs in human milk are bioavailable and influence physiologic pathways that may contribute to newborn growth and development. There is …

Manufacturing and engineering of therapeutic extracellular vesicles
… to dispose of unwanted material, extracellular vesicles (EVs) have emerged as potent messengers that package and disseminate biochemical signals. This newly recognized mode of communication between cells has brought unprecedented therapeutic opportunities; at least 8 clinical trials and 7 …

THE ROLE OF EXTRACELLULAR VESICLES IN HEART DISEASES
Background and Aim: Heart diseases, including hypertrophic cardiomyopathy (HCM) and heart failure (HF), remain among the leading causes of morbidity and mortality worldwide. Epidemiological data indicate that their burden will continue to rise in the coming years, with HF representing an expanding …

The stability of phospholipid and biomimetic polymer vesicles
… AqpZ. Previous research conducted on AqpZ:ABA vesicles showed permeabilities exceeding commercial RO membranes and high selectivity. These properties make biomimetic materials promising for RO, but investigation of their long-term chemical and physical stability under water treatment conditions …

The seminal vesicles : anatomy, comparative anatomy and development.
There are many reasons which induced me to choose this subject for a thesis. I would like to mentioned only the most important one. Between 1942 and 1945, while in the South African Medical Corps, I was posted to the Wynberg Military Hospital. During this time I was closely associated with the …

Brain-derived Extracellular vesicles as biomarkers of Parkinson’s disease
… In contrast, brain-derived extracellular vesicles (EVs) are found to be in substantial concentrations in systemic circulation, allowing for the possibility of a diagnostic blood test. In this study, we demonstrate that a higher concentration of alpha synuclein (aSyn) and phosphorylated …
