Summary: The spontaneous formation of phospholipid vesicles was explored for the production of liposomal encapsulations of bioactive compounds. Stable vesicles were produced from unrefined soybean and sunflower lecithin, and their structure and encapsulation capacity were evaluated. These vesicles demonstrated high thermal and oxidative stability, making them suitable for food applications.

Summary: Subtle variations in lipid membrane structure and composition can greatly affect the transport of functional molecules and cell functions. This study compares the permeability of bilayers made of three lipids and reveals that the structural mismatch between saturated and unsaturated alkane chains leads to looser packing in lipid bilayers and better permeability. It also shows that surface curvature in certain vesicles disturbs the bilayer structure. This information provides clues for drug development and other medical and biological studies.

Summary: The study demonstrates that SiO2 NPs can efficiently induce membrane fusion in biomimetic model membranes, likely by increasing lateral membrane tension. Real-time microscopy reveals three distinct mechanistic pathways for membrane fusion. SiO2 NPs show significant potential for inclusion in the synthetic biology toolkit for membrane remodeling and fusion in artificial cells.

Summary: This study investigates the suitability of photosensitizer PN grafted with lipid chains to form nano assemblies or mixed lipid vesicles for photodynamic therapy. The results show that PN-C-18 conjugates can control the thermodynamic and structural properties of mixtures, leading to the disintegration of vesicles due to pi-pi interactions between PN molecules.

Summary: Cellular abscission is the final step of cytokinesis. ALIX and TSG101 proteins are involved in recruiting ESCRT-III to the midbody, and together with CHMP4B, they form spiral-like structures from the midbody to the abscission site. ALIX and CHMP4B are transported in vesicles along microtubules by the kinesin-1 motor protein to the cytokinetic bridge and midbody, contributing to abscission.

Summary: This study demonstrates that the power factor of carbon nanotube (CNT) networks embedded in a polymer matrix can be significantly enhanced by adding electrically insulating microscale particles. The addition of silica particles improves the connectivity and tunneling efficiency between CNTs, leading to an increase in electrical conductivity and Seebeck coefficient, thereby boosting the power factor by more than a factor of six.
