Electroporation of cell membranes [PDF]

open access: yesBiophysical Journal, 1989
Electric pulses of intensity in kilovolts per centimeter and of duration in microseconds to milliseconds cause a temporary loss of the semipermeability of cell membranes, thus leading to ion leakage, escape of metabolites, and increased uptake by cells of drugs, molecular probes, and DNA.

Antibody binding reports spatial heterogeneities in cell membrane organization [PDF]

open access: yes, 2022
The spatial organization of cell membrane glycoproteins and glycolipids is critical for mediating the binding of ligands, receptors, and macromolecules on the plasma membrane. However, we currently do not have the methods to quantify the spatial heterogeneities of macromolecular crowding on live cell surfaces.

Oxygen reduction at the silver/hydroxide-exchange membrane interface [PDF]

open access: yes, 2008
A solid-state cell is used to study the electrocatalysis of oxygen reduction at the silver/hydroxide-exchange membrane interface. The catalyst/membrane interface exhibits improved performance in comparison to a catalyst/aqueous sodium hydroxide interface.

RNAi screening reveals a large signaling network controlling the Golgi apparatus in human cells

open access: yesMolecular Systems Biology, 2012
The Golgi apparatus has many important physiological functions, including sorting of secretory cargo and biosynthesis of complex glycans. These functions depend on the intricate and compartmentalized organization of the Golgi apparatus.

Immunocytochemical localization of the main intrinsic polypeptide (MIP) in ultrathin frozen sections of rat lens. [PDF]

open access: yes, 1983
The in situ distribution of the 26-kdalton Main Intrinsic Polypeptide (MIP or MP 26), a putative gap junction protein in ocular lens fibers, was defined at the electron microscope level using indirect immunoferritin labeling of ultrathin frozen sections ...

Human hepatic cell behavior on polysulfone membrane with double porosity level [PDF]

open access: yes, 2013
In the membrane-based bioartificial livers developed up to now,the hepatic cells were located either in the fibers lumen or in the cartridge,with limited capacity for cell hosting.Here,we designed a polysulfone (PSU) membrane with a double porosity ...

Rab35 GTPase couples cell division with initiation of epithelial apico-basal polarity and lumen opening

open access: yesNature Communications, 2016
Establishment and maintenance of apico-basal polarity in epithelial organs needs to be tightly coupled with cell division. Here the authors show that the Rab35 GTPase tethers intracellular vesicles containing key apical determinants at the cleavage site,

Mechanics and regulation of cytokinetic abscission

open access: yesFrontiers in Cell and Developmental Biology, 2022
Cytokinetic abscission leads to the physical cut of the intercellular bridge (ICB) connecting the daughter cells and concludes cell division. In different animal cells, it is well established that the ESCRT-III machinery is responsible for the ...

Automated Segmentation of Cells with IHC Membrane Staining [PDF]

open access: yes, 2011
This study presents a fully automated membrane segmentation technique for immunohistochemical tissue images with membrane staining, which is a critical task in computerized immunohistochemistry (IHC).
