in this work a new resistance model has been presented based on that of henis-tripodi which can be used for interpretation of gas permeation data in composite and asymmetric membranes. in contrast to the previous works, in this model the fraction of the support layer surface that includes the pores filled with coating material has been taken into account. the influences of the filled pores on s...

Imaging membranes in live cells with nanometer-scale resolution promises to reveal ultrastructural dynamics of organelles that are essential for cellular functions. In this work, we identified photoswitchable membrane probes and obtained super-resolution fluorescence images of cellular membranes. We demonstrated the photoswitching capabilities of eight commonly used membrane probes, each specif...
Membrane proteins remain challenging targets for structural biology, despite much effort, as their native environment is heterogeneous and complex. Most methods rely on detergents to extract membrane proteins from their native environment, but this removal can significantly alter the structure and function of these proteins. Here, we overcome these challenges with a hybrid method to study membr...
Alzheimer's disease (AD) is the most common neurodegenerative disease characterized clinically by progressive memory loss and decline in cognitive abilities and characterized pathologically by the presence of two types of abnormal deposits, i.e., senile plaques (SP) and neurofibrillary tangles (NFT), and by extensive synapse and neuronal loss. SP are composed of fibrillar amyloid beta-peptide (...
