In vitro fusion of single synaptic and dense core vesicles reproduces key physiological properties

Nature Communications, 2019
Regulated exocytosis of neuronal synaptic vesicles is substantially faster than that of endocrine dense core vesicles despite similar molecular machineries.

Structure of the cell envelope of Halobacterium halobium [PDF]

, 1976
The structure of the isolated cell envelope of Halobacterium halobium is studied by X-ray diffraction, electron microscopy, and biochemical analysis. The envelope consists of the cell membrane and two layers of protein outside. The outer layer of protein

Real-time monitoring of proton exchange membrane fuel cell stack failure [PDF]

, 2016
Uneven pressure drops in a 75-cell 9.5-kWe proton exchange membrane fuel cell stack with a U-shaped flow configuration have been shown to cause localised flooding.

LRRC45 Is a Centrosome Linker Component Required for Centrosome Cohesion

Cell Reports, 2013
During interphase, centrosomes are connected by a proteinaceous linker between the proximal ends of the centrioles, which is important for the centrosomes to function as a single microtubule-organizing center.

Plasma membrane integrity in health and disease: significance and therapeutic potential

Cell Discovery, 2021
Maintenance of plasma membrane integrity is essential for normal cell viability and function. Thus, robust membrane repair mechanisms have evolved to counteract the eminent threat of a torn plasma membrane.

A model of membrane contraction predicting initiation and completion of bacterial cell division [PDF]

, 2013
Bacterial cell division involves a complex and dynamic sequence of events whereby polymers of the protein FtsZ assemble at the division plane and rearrange to achieve the goal of contracting the cell membrane at the site of cell division, thus dividing ...

The Flemmingsome reveals an ESCRT-to-membrane coupling via ALIX/syntenin/syndecan-4 required for completion of cytokinesis

Nature Communications, 2020
ESCRT filaments drive the final abscission between two daughter cells but how they physically interact with the membrane is unclear. Using proteomics, the authors show that syndecan-4/syntenin/ALIX couples the ESCRT machinery to the abscission site and ...

The model of stress distribution in polymer electrolyte membrane [PDF]

Journal of The Electrochemical Society, 160 (10) F1129-F1137 (2013), 2014
An analytical model of mechanical stress in a polymer electrolyte membrane (PEM) of a hydrogen/air fuel cell with porous Water Transfer Plates (WTP) is developed in this work. The model considers a mechanical stress in the membrane is a result of the cell load cycling under constant oxygen utilization.
