Angiogenesis is a tightly regulated process where a number of different players are involved. Recently, a role for membrane vesicles actively released from cells has been proposed. Virtually all cell types may release non-apoptotic membrane vesicles in the nano-size range containing critical components of the cell of origin. The two main categories of these vesicles include exosomes and microve...

In higher eukaryotes, phospholipid and cholesterol synthesis occurs mainly in the endoplasmic reticulum, whereas sphingomyelin and higher glycosphingolipids are synthesized in the Golgi apparatus. Lipids like cholesterol and sphingomyelin are gradually enriched along the secretory pathway, with their highest concentration at the plasma membrane. How a cell succeeds in maintaining organelle-spec...

Extracellular micro- and nano-scale membrane vesicles produced by different cells are recognised as an essential entity of physiological fluids in a variety of organisms and function as mediators of intercellular communication employed for the regulation of multiple systemic and local processes. In the last decade, an exponential amount of experimental work was dedicated to exploring the biogen...

Elastic theory of low-dimensional continua and its applications in bio-and nano-structures This review presents the elastic theory of low-dimensional (one-and two-dimensional) continua and its applications in bio-and nano-structures. First, the curve and surface theory, as the geometric representation of the low-dimensional continua , is briefly described through Cartan moving frame method. The...

      In this work we sought to determine whether vesicles (liposomes/niosomes) were able to enhance finasteride concentration in the dermis layer, including the pilosebaceous units (PSU). Such enhancement could be beneficial in the treatment of some androgen-related skin disorders. Hamster flank skin was used to study  <span styl...

Bacterial outer membrane vesicles (OMVs) are small unilamellar proteoliposomes, involved in various functions including cell-to-cell signalling and protein excretion. We have engineered the OMVs of Escherichia coli to nano-scaled bioreactors for biotransformation fatty acids by targeting a acid double bond hydratase Stentrophomonas maltophilia (SmOhyA) and/or photoactivated decarboxylase from C...
