Advances in Isotope Labeling for Solution Nucleic Acid Nuclear Magnetic Resonance Spectroscopy

ChemPlusChem, EarlyView.
Recent advances in the field of nucleic acid nuclear magnetic resonance (NMR) are presented. Stable isotope labeling protocols and new approaches to segmentally label nucleic acid with NMR‐active residues are summarized. The novel methods will have a strong impact on the future of nucleic acid NMR and the characterization of structure and dynamics of ...

Mechanical unloading is accompanied by reverse metabolic remodelling in the failing heart: Identification of a novel citraconate‐mediated pathway

European Journal of Heart Failure, EarlyView.
Aims Although functional recovery of the failing heart with left ventricular assist device (LVAD) unloading can occur, the underpinning mechanism is unclear. We aimed to characterize the effect of myocardial biochemical effect of LVAD support in vivo and in vitro.

Can adenine nucleotides predict primary nonfunction of the human liver homograft? [PDF]

, 1994
Sixty-eight primary liver grafts were analyzed to see whether adenine nucleotides (AN: ATP, ADP, and AMP) or purine catabolites (PC: adenosine, inosine, hypoxanthine, and xanthine) of tissue or effluent can predict primary graft nonfunction.

Interpretation of in vitro concentration‐response data for risk assessment and regulatory decision‐making: Report from the 2022 IWGT quantitative analysis expert working group meeting

Environmental and Molecular Mutagenesis, EarlyView.
Abstract Quantitative risk assessments of chemicals are routinely performed using in vivo data from rodents; however, there is growing recognition that non‐animal approaches can be human‐relevant alternatives. There is an urgent need to build confidence in non‐animal alternatives given the international support to reduce the use of animals in toxicity ...

Molybdenum cofactor (chlorate-resistant) mutants of Klebsiella pneumoniae M5al can use hypoxanthine as the sole nitrogen source. [PDF]

, 1992
Selection for chlorate resistance yields mol (formerly chl) mutants with defects in molybdenum cofactor synthesis. Complementation and genetic mapping analyses indicated that the Klebsiella pneumoniae mol genes are functionally homologous to those of ...

Severity of effect considerations regarding the use of mutation as a toxicological endpoint for risk assessment: A report from the 8th International Workshop on Genotoxicity Testing (IWGT)

Environmental and Molecular Mutagenesis, EarlyView.
Abstract Exposure levels without appreciable human health risk may be determined by dividing a point of departure on a dose–response curve (e.g., benchmark dose) by a composite adjustment factor (AF). An “effect severity” AF (ESAF) is employed in some regulatory contexts.

Glutaredoxin GRXS17 associates with the cytosolic iron-sulfur cluster assembly pathway [PDF]

, 2016
Cytosolic monothiol glutaredoxins (GRXs) are required in iron-sulfur (Fe-S) cluster delivery and iron sensing in yeast and mammals. In plants, it is unclear whether they have similar functions.

Inherited metabolic epilepsies–established diseases, new approaches

Epilepsia Open, EarlyView.
Abstract Inherited metabolic epilepsies (IMEs) represent the inherited metabolic disorders (IMDs) in which epilepsy is a prevailing component, often determining other neurodevelopmental outcomes associated with the disorder. The different metabolic pathways affected by individual IMEs are the basis of their rarity and heterogeneity.
