'Ant bridge'-inspired nanoparticle assembly fixes broken electrical circuits
Colonies of social insects are capable of self-organizing and accomplishing complex tasks through individual interactions. For example, to march across large gaps, ants grip the bodies of each other, forming a living bridge that allows the colonies to reach the other side. Inspired by this swarm behavior of ants, scientists from the Chinese University of Hong Kong developed a nanoparticle self-ass

Spontaneous waves of cortical spreading depolarization (CSD) are induced in the setting of acute focal ischemia.

Furthermore, CSD induces secondary irreversible damage in the ischemic brain, suggesting that K+ homeostasis might constitute…

The most common underlying causes of genetic intractability are restriction-modification (RM)…

Protective role for the N-terminal domain of {alpha}-dystroglycan in Influenza A virus proliferation [Medical Sciences]
α-Dystroglycan (α-DG) is a highly glycosylated basement membrane receptor that is cleaved by the proprotein convertase furin, which releases its N-terminal domain (α-DGN). Before cleavage, α-DGN interacts with the glycosyltransferase LARGE1 and initiates functional O-glycosylation of the mucin-like domain of α-DG. Notably, α-DGN has been detected in a wide variety…

FGF23 levels are regulated by the transcriptional event and posttranslational cleavage into inactive fragments before its secretion. For…
