Thermally assisted ion beam etching of polytetrafluoroethylene, a new technique for high aspect ratio etching of MEMS [PDF]

, 1996
In micromechanics, the etching of high aspect ratio structures in polymers is a prime technology. Normally, oxygen-based reactive ion etching or the LIGA technique are used to achieve this goal.

Adversarial Erasing Enhanced Multiple Instance Learning (siMILe): Discriminative Identification of Oligomeric Protein Structures in Single Molecule Localization Microscopy

Advanced Intelligent Systems, EarlyView.
Hallgrimson et al. introduce a machine learning algorithm, siMILe, that takes features of single‐molecule localization microscopy localization clusters (e.g., size and sphericity) and finds the clusters that are associated with certain cell conditions (such as differential protein expression or drug treatment).

Therapeutic Applications of Stimuli‐Based Release and Engineering of Extracellular Vesicles

Advanced NanoBiomed Research, EarlyView.
This review summarizes the effects of endogenous and exogenous stimuli, their effects on the natural release of extracellular vesicles, as well as their uptake and release. It also gives an overview of stimuli‐responsive EVs and their therapeutic applications. Extracellular vesicles (EVs), nano‐ to microsized lipid bilayer membrane‐bound particles, are

Regulation of membrane scission in yeast endocytosis

, 2018
Endocytosis is an ancient pathway that regulates communication of the cell with its environment. During this process, the plasma membrane is reshaped in a controlled sequence: a flat membrane forms an invagination that undergoes scission to produce a cargo-filled vesicle. Breaking the membrane invagination to form a vesicle is perhaps the most dramatic

Recruitment dynamics of ESCRT-III and Vps4 to endosomes and implications for reverse membrane budding

eLife, 2017
The ESCRT machinery mediates reverse membrane scission. By quantitative fluorescence lattice light-sheet microscopy, we have shown that ESCRT-III subunits polymerize rapidly on yeast endosomes, together with the recruitment of at least two Vps4 hexamers.

Thermal oxidation kinetics of additive free polyamide 6-6 [PDF]

, 2013
Thermal aging of an additive free PA 6-6 has been elucidated at 90, 100, 120, 140, 150 and 160 C in airventiled ovens by Fourier transform infrared spectrophotometry, viscosimetry in molten state and uniaxial tensile testing.

Advancing design strategies in smart stimulus‐responsive liposomes for drug release and nanomedicine

BMEMat, EarlyView.
Schematic illustration of stimulus‐responsive liposomes designed for controlled drug release and nanomedicine. The innermost circle represents different liposomal structures, including unilamellar, multilamellar, and multivesicular liposomes. The middle layer illustrates the responsive phospholipid components.

Regulators of Lysosome Function and Dynamics in Caenorhabditis elegans

G3: Genes, Genomes, Genetics, 2017
Lysosomes, the major membrane-bound degradative organelles, have a multitude of functions in eukaryotic cells. Lysosomes are the terminal compartments in the endocytic pathway, though they display highly dynamic behaviors, fusing with each other and with

Macrocyclic colibactin induces DNA double-strand breaks via copper-mediated oxidative cleavage. [PDF]

, 2019
Colibactin is an assumed human gut bacterial genotoxin, whose biosynthesis is linked to the clb genomic island that has a widespread distribution in pathogenic and commensal human enterobacteria.
