Structural, functional, and regulatory evaluation of a cysteine post-translationally modified Gcn5-related N-acetyltransferase.

Polyamines within the cell are tightly regulated by spermidine/spermine N-acetyltransferase (SSAT) enzymes. While several SSATs have been investigated in different bacterial species, there is still a significant gap in knowledge about which proteins are functional SSATs in many organisms. For example, while it is known that Pseudomonas aeruginosa synthesizes the polyamine spermidine, the SSAT that acetylates this molecule and its importance in regulating intracellular polyamines remains unknown.

N-terminal domain swapping: A new paradigm for spermidine/spermine N-acetyltransferase (SSAT) protein structures?

Enterococcus faecalis is a multi-drug-resistant human pathogen that is found in a variety of environments and is challenging to treat. Under stress conditions, some bacteria regulate intracellular polyamine concentrations via polyamine acetyltransferases to reduce their toxicity. The E.

Impact of myelodysplasia-related and additional gene mutations in intensively treated patients with -mutated AML.

This study aimed to evaluate the impact of the myelodysplasia-related gene (MRG) as well as additional gene mutations on outcomes in intensively treated patients with -mutated ( ) AML. Targeted DNA sequencing of 263 genes was performed in 568 AML patients (median age: 59 years) entered into the prospective AMLSG 09-09 treatment trial. Most commonly co-mutated genes were (49.

Introducing the forearm fracture index to define the diametaphyseal junction zone through clinical evaluation in a cohort of 366 diametaphyseal radius fractures.

Background: Unstable diametaphyseal radius fractures (DMRFs) can be prone to complications, and treatment strategies are heterogeneous. Studies are difficult to interpret as definitions of the diametaphyseal junction zone (DMJZ) are impractical for clinical use, imprecise, or prone to error.

Methods: We introduce the forearm fracture index (FFI) to define DMRFs in radiographs and ultrasound.

Hybrid Virtual Coaching and Telemonitoring in COPD Management: The CAir Randomised Controlled Study.

Objective: To investigate the effectiveness of 12-weeks hybrid virtual coaching on health-related quality-of-life (HrQoL) in patients with stable COPD.

Methods: We equipped all patients with a CAir Desk for telemonitoring, the intervention group additionally received hybrid virtual coaching through the built-in smartphone. The multimodal intervention based on the Living well with COPD programme, containing educational content, physical activity coaching, and home-based exercises.
