Article Synopsis
- Researchers analyzed serum metabolites from 83 patients to find early markers for predicting SARS-CoV-2 infection severity.
- High levels of de-aminated amino acid catabolites, linked to nucleotide synthesis, were identified as potential early indicators of severe disease and correlated with viral load.
- Animal studies showed that amino acid de-amination and nucleotide synthesis led to abnormal cell growth in the lungs, suggesting that early lung tissue changes could indicate future inflammation and disease progression.
Article Synopsis
- * The new method enhances mirror production by addressing issues like corrosion and thermal deformation, providing better stability and performance for high-quality x-ray optics.
- * A vacuum degassing technique was developed to reduce bubble pit formation during fabrication, resulting in the successful creation of three pit-free mirrors for the FOXSI-4 project, with precise accuracy and performance comparable to leading x-ray missions.
Damage thresholds and structures on a metal aluminum and an aluminum oxide crystal induced by the soft x-ray free electron laser irradiations were evaluated. Distinctive differences in damage thresholds and structures were observed for these materials. On the aluminum oxide crystal surface, in particular, a novel, to the best of our knowledge, surface processing, which we suggest defining as "peeling," was recognized.

We found that anserine is present at low concentrations (low micromolar range) in both cardiac and skeletal muscles, and that anserine content in skeletal muscle is ~15 times higher than in cardiac muscle (cardiac muscle: 10.1 ± 13.

In OAM, a flow of slurry, dispersed with organic particles, locally removes the surface of a workpiece in contact with a rotating machining tool. A computer-controlled machining system was used to perform the selective removal of a fused silica surface at a spatial resolution of 200 µm.
