Reconstructed Polyamide Nanolayers via Two‐Stage Interfacial Polymerization Engineering for Precise Ion Sieving

Advanced Science
Efficient lithium extraction from brines remains challenging due to the comparable hydrated radii of Li+ and Mg2+ and the extreme ionic strength of the feed solutions. In this work, a reconstructed polyamide (PA) nanofiltration membrane was developed via

Cryo-EM structures of intermediates suggest an alternative catalytic reaction cycle for cytochrome c oxidase

Nature Communications, 2021
Cytochrome c oxidase is a fundamental enzyme of life and its mechanism is not fully understood yet. Here, the authors present four cryo-EM structures of different intermediate states, which suggest an alternative cytochrome c oxidase reaction cycle.

Receptor-Mediated Endocytosis of a Cylindrical Nanoparticle in the Presence of Cytoskeleton Substrate

, 2019
Internalization of particles by cells plays a crucial role for adsorbing nutrients and fighting infection. Endocytosis is one of the most important mechanisms of the particles uptake which encompass multiple pathways.

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

FEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Lipid membrane instability and poration driven by capacitive charging

, 2010
A new model for the interaction of an electric pulse with a lipid membrane is proposed. Using this model we show that when a DC electric pulse is applied to an insulating lipid membrane separating fluids with different conductivities, the capacitive ...

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Kinetic selectivity in metal-organic framework chemical sensors

Nature Communications
Selective detection of specific volatile organic compounds (VOCs) is crucial for health, safety, and environmental applications, but current sensors suffer from poor selectivity and struggle to measure specific VOCs in the presence of interfering ...

Techno-economic process optimization for a range of membrane performances: What provides real value for point-source carbon capture?

Carbon Capture Science & Technology
Membranes provide a unique opportunity for heavy industry decarbonization and a real solution requires optimal system design. We use a superstructure process model to minimize capital and operational expenses for post-combustion carbon capture systems ...
