Crosslinking by ZapD drives the assembly of short FtsZ filaments into toroidal structures in solution [PDF]
Cell division in Escherichia coli relies on the Z ring, a cytoskeletal structure that acts as a scaffold for the assembly of the divisome. To date, the detailed mechanisms underlying the assembly and stabilization of the Z ring remain elusive. This study

Real-world modeling and simulation for the self-organized toroidal packing of a DNA chain [PDF]
We performed experiments to elucidate the conformations of a single centimeter-sized bead chain through the mechanical vertical agitation under different crowding levels mediated by granular spheres.

An adenine model of inborn metabolism errors alters TDP-43 aggregation and reduces its toxicity in yeast revealing insights into protein misfolding diseases [PDF]
TDP-43 is linked to human diseases such as amyotrophic lateral sclerosis (ALS) and frontotemporal degeneration (FTD). Expression of TDP-43 in yeast is known to be toxic, cause cells to elongate, form liquid-like aggregates, and inhibit autophagy and ...

Crystal structure and catalytic mechanism of PL35 family glycosaminoglycan lyases with an ultrabroad substrate spectrum [PDF]
Recently, a new class of glycosaminoglycan (GAG) lyases (GAGases) belonging to PL35 family has been discovered with an ultrabroad substrate spectrum that can degrade three types of uronic acid-containing GAGs (hyaluronic acid, chondroitin sulfate and ...

Research Note: Reticulocytes and related erythroid atypia of ducks—indicators of stress or pathology? [PDF]
: Two kinds of reticulocytes, and atypical erythroid cells, were found in the blood of apparently healthy ducks with Wright–Giemsa (W–G) stain. The reticulin of network-type examples (nRtc) is of a large complex (3-D) form.

Complete and robust magnetic field confinement by superconductors in fusion magnets [PDF]
The fusion created by magnetically confined plasma is a promising clean and essentially unlimited future energy source. However, there are important problems hindering controlled fusion like the imperfect magnetic confinement and the associated plasma ...

The ring-shaped spatial distribution of the argon excimer, $$\hbox {Ar}_2^{*}$$ Ar 2 ∗ , in the effluent of the kINPen-sci [PDF]
Spatially resolved measurements of the argon excimer, $$\hbox {Ar}_2^{*}$$ Ar 2 ∗ , were performed in the effluent of a cold atmospheric plasma jet (CAPJ), the so called kINPen-sci, using cavity ringdown spectroscopy.

Cryopreservation of bovine sperm causes single-strand DNA breaks that are localized in the toroidal regions of chromatin [PDF]
Background Sperm cryopreservation is widely used in the cattle industry, as it allows for disassociating the localization of sires and the collection of semen from the timing of artificial insemination.
