The fluid mosaic membrane model proved to be a very useful hypothesis in explaining
many, but certainly not all, phenomena taking place in biological membranes. New …

Increased levels of apolipoprotein B (apoB)-containing lipoproteins, such as low density
lipoproteins (LDL) and chylomicron remnants, are associated with the development of …

In the last few years several experimental strategies based on epi-, confocal and two photon
excitation fluorescence microscopy techniques have been employed to study the lateral …

Extracellular vesicles (EVs) contribute to several pathophysiological processes and appear
as emerging targets for disease diagnosis and therapy. However, successful translation from …

Lipid rafts are specialized regions of cell membranes enriched in cholesterol and
sphingolipids that are involved in immune activation and signaling. Studies in T-cells …

Lipid-bilayer membranes are formed by self-assembly processes. The molecular
interactions within the bilayer and with the environment impart a unique trans-bilayer lateral …

Contents Native sperm is only marginally stable after collection. Cryopreservation of semen
facilitates transport and storage for later use in artificial reproduction technologies, but …

The concept of transient nanometric domains known as lipid rafts has brought interest to
reassess the validity of the Singer–Nicolson model of a fluid bilayer for cell membranes …

The cryopreservation of human spermatozoa has been an option for patients undergoing
chemo or radiotherapies since the late 1950s. Presently, there are different techniques for …

Presence of microdomains has been postulated in the cell membrane, but two-dimensional
distribution of lipid molecules has been difficult to determine in the submicrometer scale. In …
