Hypoaminoacidemia and Pyroglutamic Aciduria: Potential Biomarkers in Malnutrition‐Related Hyperammonemia

JIMD Reports, Volume 67, Issue 1, January 2026.
ABSTRACT Hyperammonemia is a medical emergency, and the cause must be identified quickly in order to treat appropriately. Malnutrition is a known risk factor for hyperammonemia; however, there are limited reliable lab indicators used to identify malnutrition.

Cholesteryl phenylacetate

Acta Crystallographica Section E Structure Reports Online, 2006
The mol­ecule of the title compound, C35H52O2, adopts an extended conformation, with the phenylacetate group twisted by 69.3 (1)° from the least-squares plane of the tetra­cyclic ring system. In the crystal structure, the mol­ecules are aligned in an anti­parallel fashion to form alternate layers.

Biochemical, Clinical, and Functional Characterization of a Rare c.‐106C>A Promoter Region Variant in Late‐Onset Ornithine Transcarbamylase Deficiency: A Multifamily Case Series

JIMD Reports, Volume 67, Issue 1, January 2026.
ABSTRACT Ornithine transcarbamylase (OTC) deficiency can present during the neonatal period, infancy, or adulthood. Late‐onset phenotypes are influenced by residual enzyme activity and OTC gene expression. The objective of this study was to assess the pathogenicity of a rare promoter region variant, c.‐106C>A.

Comparative Analysis of Metabolites in Kudingcha Rice Wine Fermented With Different Yeast Strains Using Nontargeted Metabolomics

Journal of Food Biochemistry, Volume 2026, Issue 1, 2026.
In this study, fermentation was performed with Kuding tea and glutinous rice as raw materials and different yeast strains (L254 (Saccharomyces cerevisiae), FBKL2.0235 (Trichomonascus ciferrii), and Angel yeast). The fermentation characteristics and the volatile and nonvolatile components of Kudingcha rice wine were analyzed by examining physical and ...

C‐Acylation of Guaiacol with Acetic Acid Over Solid Acid Catalysts Under Mild Reaction Conditions

ChemCatChem, Volume 17, Issue 23, December 8, 2025.
Direct acylation of guaiacol (G) with acetic acid (AA) over Aquivion® PW87 under mild conditions affords 4‐hydroxy‐3‐methoxyacetophenone (p‐HMAP) with a remarkable para/ortho molar ratio of 26:1. Combined DFT and experimental studies reveal an acid‐catalyzed intermolecular acyl transfer via 2‐methoxyphenyl acetate (MPA), enabling a highly selective and
