Serial amplification of tau filaments using Alzheimer's brain homogenates and C322A or C322S recombinant tau

FEBS Letters, EarlyView.
We investigated the seeded assembly of 0N3R tau and two variants, C322A and C322S, designed to model the mutation landscape at residue 322, using Alzheimer's disease brain homogenates in a real‐time quaking‐induced conversion (RT‐QuIC) assay. The C322A variant formed filaments that partially resembled the paired helical filament (PHF) structure ...

A Community-Driven Validation Service for Standard Medical Imaging Objects [PDF]

, 2018
Digital medical imaging laboratories contain many distinct types of equipment provided by different manufacturers. Interoperability is a critical issue and the DICOM protocol is a de facto standard in those environments.

Single cis‐elements in brassinosteroid‐induced upregulated genes are insufficient to recruit both redox states of the BIL1/BZR1 DNA‐binding domain

FEBS Letters, EarlyView.
Phytohormone brassinosteroid‐induced gene regulation by the transcription factor BIL1/BZR1 involves redox‐dependent DNA‐binding alternation and interaction with the transcription factor PIF4. The reduced BIL1/BZR1 dimer binds preferred cis‐elements, while oxidation alters its oligomerization state and disrupts DNA‐binding ability.

ACSS2 involved in acetyl‐CoA synthesis regulates skeletal muscle function

FEBS Letters, EarlyView.
The enzyme acyl‐coenzyme A synthetase short‐chain family member‐2 (ACSS2) catalyzes the conversion of acetate to acetyl‐CoA, but its function in skeletal muscle is unclear. We studied ACSS2 deficiency in mouse and fly models. Skeletal muscle from the mouse model showed atrophic fibers, excess lipid, and depleted NADH.

Catheter-Directed Thrombolysis in the treatment of acute Portomesenteric Vein Thrombosis after Laparoscopic Sleeve Gastrectomy

Thrombosis Journal, 2022
Background Portomesenteric Vein Thrombosis (PMVT) following Laparoscopic Sleeve Gastrectomy (LSG) is an uncommon but potentially debilitating complication.

Mechanistic basis for inhibition of the extended‐spectrum β‐lactamase GES‐1 by enmetazobactam and tazobactam

FEBS Letters, EarlyView.
Antimicrobial resistance (AMR) is of huge importance, resulting in over 1 million deaths each year. Here, we describe how a new drug, enmetazobactam, designed to help fight resistant bacterial diseases, inhibits a key enzyme (GES‐1) responsible for AMR. Our data show it is a more potent inhibitor than the related tazobactam, with high‐level computation

C9orf72 ALS‐causing mutations lead to mislocalization and aggregation of nucleoporin Nup107 into stress granules

FEBS Letters, EarlyView.
Mutations in the C9orf72 gene represent the most common genetic cause of amyotrophic lateral sclerosis (ALS), a fatal neurodegenerative disease. Using patient‐derived neurons and C. elegans models, we find that the nucleoporin Nup107 is dysregulated in C9orf72‐associated ALS. Conversely, reducing Nup107 levels mitigates disease‐related changes.
