Abstract The nucleolus is a membrane-less organelle sequestered from the nucleus by liquid droplet formation through liquid–liquid phase separation (LLPS). It plays important roles in cell homoeostasis its internal thermodynamic changes. Reversible nucleolar transitions between coalescence and dispersion are dependent on concentrations, conformations interactions of molecular droplet-forming co...

Orientational memory in interfacial liquid crystal films occurs when cells heated above the isotropic transition temperature return to their initial ordered texture upon cooling. First observed over 80 years ago, the origins of orientational memory, which is sometimes called the surface memory effect, remain poorly understood. In this study, films of the thermotropic liquid crystal 4'-octyl-4-c...

We perform molecular dynamics simulations of 512 waterlike molecules that interact via the TIP5P potential and are confined between two smooth hydrophobic plates that are separated by 1.10 nm. We find that the anomalous thermodynamic properties of water are shifted to lower temperatures relative to the bulk by approximately 40 K. The dynamics and structure of the confined water resemble bulk wa...

Lipid rafts are localized mainly at the level of the plasma-membrane, but they can also form within internal membrane compartments, such as the Golgi appara-Lipid Rafts, Caveolae, and Caveolins For many years, scientists viewed the lipid bilayer of the tus (Gkantiragas et al., 2001). Therefore, the partitioning of caveolins into these liquid-ordered domains may be-plasma membrane as a two-dimen...

Bulk endocytosis contributes to the maintenance of neurotransmission at the amphibian neuromuscular junction by regenerating synaptic vesicles. How nerve terminals internalize adequate portions of the presynaptic membrane when bulk endocytosis is initiated before the end of a sustained stimulation is unknown. A maturation process, occurring at the end of the stimulation, is hypothesised to prec...

Flexoelectric liquid crystalline membranes immersed in asymmetric viscoelastic media is a material system model with physiological applications such as outer hair cells (OHCs), where membrane oscillations generate bulk flow. Motivated by this process, here we extend our previous work characterizing the force transmission output of addition to fluid flow, since solid–fluid interactions are an es...

The role of liquid membrane phenomenon has been studied in the anti bacterial activity of cephalosporins i.e. Cefuroxime sodium. In our earlier publication [1] it was reported that hydraulic permeability data obtained to demonstrate the existence of liquid membrane in series with supporting membrane generated by Cefuroxime sodium. Transport of selected permeants (glucose, PABA, glycine, and ion...

A mathematical model considering mass and momentum transfer was developed for simulation of ethanol dewatering via pervaporation process. The process involves removal of water from a water/ethanol liquid mixture using a dense polymeric membrane. The model domain was divided into two compartments including feed and membrane. For a description of water transport in ...

The dynamics of water confined in various self-assembled liquid-crystalline phases of the system Dimodan U/J–R(+)-limonene–water have been investigated by dielectric relaxation spectroscopy (DRS) over a wide range of frequencies (0.2 # n/GHz # 50). For all phases, two water-related Debye processes were detected, one slightly slower, the other considerably slower, than bulk water. Besides these ...
