Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Key considerations for preparing ion-milled lithium metal cross-sectional samples

Methods in Microscopy
Detailed understanding of lithium anode morphology is essential for solid-state battery technology development. Non-optimal interfacial contacts and structural changes during cycling present significant challenges, limiting both battery performance and ...

Extending the measurement capabilities of 3D X-ray microscopy to dimensional metrology

International Journal of Metrology and Quality Engineering
In the industry of manufactured and assembled devices, the miniaturization and integration of small components with feature sizes on the order of 10 mm or smaller leads to new demands for inspection measurement systems.

Fracture mechanics by three-dimensional crack-tip synchrotron X-ray microscopy

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2015
To better understand the relationship between the nucleation and growth of defects and the local stresses and phase changes that cause them, we need both imaging and stress mapping.

Finding novel vulnerabilities of hypomorphic BRCA1 alleles

Molecular Oncology, EarlyView.
Synthetic lethality screens performed to identify novel vulnerabilities often model complete gene loss, thereby overlooking patient‐derived hypomorphic mutations. In this study, we have performed genome‐wide CRISPR screens on BRCA1 hypomorphic mutations, showing BRCA1I26A behaves like wild‐type, while BRCA1R1699Q mimics deficiency. Furthermore, we have

Assessment of deep-learning-based resolution recovery algorithm relative to imaging system resolution and feature size

Methods in Microscopy
High-resolution X-ray microscopy is crucial for non-destructive materials characterization, but achieving both high resolution and maintaining a wide field of view often necessitates time-consuming approaches. Deep learning super-resolution methods based

Phase evolution in single-crystalline LiFePO4 followed by in situ scanning X-ray microscopy of a micrometre-sized battery

Nature Communications, 2015
LiFePO4 is one of the most frequently studied positive electrode materials for lithium-ion batteries during the last years. Nevertheless, there is still an extensive debate on the mechanism of phase transformation.

Cancer cell‐intrinsic type 1 interferon: production, signaling, and outcomes within sex‐biased, female malignancies

Molecular Oncology, EarlyView.
The cell‐autonomous roles of interferon type 1 vary based on duration and intensity. While acute, robust signaling results in cancer cell cytotoxic effects, sustained, low‐level signaling is associated with tumor‐promoting effects. This review summarizes current research of IFN‐1 in cancer and within the clinical setting, with an emphasis on female ...

Characterising the structural properties of polymer separators for lithium-ion batteries in 3D using phase contrast X-ray microscopy

, 2016
Separators are an integral component for optimising performance and safety of lithium-ion batteries; therefore, a clear understanding of how their microstructure affects cell performance and safety is crucial. Phase contrast X-ray microscopy is used here
