Adding mechanistic depth to understanding permeability switching transients in a biological membrane and its implications to nerve conduction regulation

Computational and Mathematical Biophysics
We have developed a quadratic control policy describing permeability switching transients in a biological membrane and the mechanisms which govern nerve conduction regulation.

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

FEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

Increasing phospholipid biomimicry governs water permeability in droplet interface bilayers

Droplet
Water transport across lipid bilayers is a fundamental biological process, but most model systems fail to capture the molecular complexity of biological cell membranes.

Phenylalanine Increases Membrane Permeability [PDF]

Journal of the American Chemical Society, 2017
Biological membranes are a crucial aspect of living systems, controlling the organization and distribution of different chemical components. Control of membrane permeability is especially important for processes such as electron transport in metabolism and signal propagation in nerve cells.

Thin film composite hollow fibre membrane for pharmaceutical concentration and solvent recovery

, 2021
A 100-piece hollow fibre thin-film composite membrane module was successfully developed for pharmaceutical concentration and solvent recovery. To increase its packing density, thinner P84 polyimide hollow fibre substrates were spun using a smaller ...

Hydrostatic pressure activates HIF‐1α via β‐catenin to promote stemness in breast cancer cells

FEBS Open Bio, EarlyView.
To mimic the elevated intestinal fluid pressure in breast cancers, we loaded human breast cancer cells (MCF‐7, MDA‐MB‐453, and BT‐474) to 50 mmHg hydrostatic pressure. Hydrostatic pressure exposure upregulated HIF‐1α and induced stemness in MCF‐7 and BT‐474 cells.

ULTRASTRUCTURE AND PERMEABILITY OF NUCLEAR MEMBRANES [PDF]

The Journal of Cell Biology, 1965
The fine structures of nuclear envelopes known to have different permeability properties were compared. Membranes of salivary gland cell nuclei of Drosophila (third instar) and Chironomus (prepupae), which are strong barriers to ion diffusion, and membranes of oocyte nuclei (germinal vesicle) of Xenopus and Triturus, which are much more ion-permeable ...

Aquaporin‐3 and aquaporin‐5 impact the development of pancreatic ductal adenocarcinoma spheroids

FEBS Open Bio, EarlyView.
Schematic representation of the role of aquaporin‐3 (AQP3) and aquaporin‐5 (AQP5) in pancreatic ductal adenocarcinoma (PDAC). Both proteins are upregulated in PDAC and are associated with tumor progression and metastatic potential. Silencing AQP3 or AQP5 in PDAC spheroids results in decreased diameter, area, and overall growth, underscoring their key ...
