Enzymatic Basis for the Oxidative Branch of Aromatic Amino Acid Fermentation Leading to p‐cresol Formation

Advanced Science, Volume 13, Issue 34, 19 June 2026.
In anaerobic bacteria, tyrosine serves as an electron donor in the oxidative Stickland fermentation branch, generating p‐hydroxyphenylacetate, ATP and reduced ferredoxin for decarboxylation into p‐cresol. ABSTRACT The phenolic metabolite p‐cresol is a byproduct of tyrosine fermentation by certain strictly anaerobic bacteria, including the human gut ...

Vitamins as potent cancer treatments through regulating the activity and expression of MMP‐2 and MMP‐9

Bulletin of the Korean Chemical Society, Volume 47, Issue 6, Page 745-755, June 2026.
Vitamins could regulate both MMP‐2 and MMP‐9 expression and activity through transcriptional and MAPK signaling pathway modulation. This study highlights the potential of vitamins as low‐toxicity therapeutic or adjunct agents for targeting MMP‐mediated cancer progression. Abstract Matrix metalloproteinases (MMP‐2 and MMP‐9) are key regulators of cancer

Pediatric Wilson Disease in Sudan: A Rare Case, Sudan Conflict and Diagnostic Challenges

Clinical Case Reports, Volume 14, Issue 6, June 2026.
ABSTRACT Wilson disease is rarely reported among African children. Wilson disease is due to a mutation in ATP7B on an autosomal recessive pattern, which causes defective copper excretion and copper accumulation in tissues such as liver and brain.

Bioenhancer‐Driven Modulation of Membrane Dynamics Improves B‐Vitamin Uptake in Caco‐2 Cells

ChemFoodChem, Volume 2, Issue 2, June 2026.
Natural bioenhancers such as extracts from ginger, turmeric, black pepper, and spearmint increase the uptake of vitamins B1, B5, B6, and B7 in Caco‐2 cells. Micellized formulations further increase efficacy. These findings indicate that altered membrane fluidity contributes to enhanced cellular absorption, providing a new route to improve vitamin B ...
