Mass spec : the biography of a scientific instrument
Over the past century, the mass spectrometer has become commonplace in scientific fields ranging from chemistry to geology to environmental science. Its ability to identify compounds and determine concentrations of those compounds leads to a wide variety of applications, from environmental …

ATR SIGNALING IN GENOME REPLICATION AND MAINTENANCE
… and may also involve protein stabilization of specific HR factors. Interestingly, cancer cells seem to exhibit a stronger dependency on ATR signaling for maintaining the levels of HR factors, and I propose that elevated constitutive ATR signaling caused by augmented replication stress in cancer …

Mechanisms and regulation of dsDNA break repair in the Sulfolobus genus of thermophilic archaea
… life. Double stranded DNA (dsDNA) breaks are especially toxic as both antiparallel strands of DNA are severed. The most high fidelity mechanism available to repair this damage is homologous recombination, a mechanism that uses homology from the sister chromatid to replace any lost information. …

Reactions of S-nitrosothiols with biomimetic iron complexes and other transition metals
… Br, or I, were prepared, and structurally and spectroscopically characterized. The reactivity of these complexes toward NO (g) and NO₂ (g) in solution was explored and characterized. These complexes were then incorporated into test strips and syringes to provide devices that can qualitatively, …

Structure Elucidation of Bioactive Compounds Isolated from Endophytes of Alstonia scholaris and Acmena graveolens
… and identified based on NMR, infrared, and mass spectral data. The compounds identified are 19,20-epoxycytochalasin C; 19,20epoxycytochalasin D; and xylobovide. Two other compounds, fusaric acid and dehydrofusaric acid, were discovered in an endophyte of the Hypocreales family inhabiting the …

The metabolic sequelae of oesophago-gastric resection
… of day and night time hypoglycaemia. RNAseq and mass spectrometry based peptidomics of human and murine enteroendocrine cells in the pre- and post-operative populations revealed no significant change in the underlying cellular pathways for nutrient sensing and gut hormone secretion, indicating …
