GSTU43 gene involved in ALA-regulated redox homeostasis, to maintain coordinated chlorophyll synthesis of tomato at low temperature

open access: yesBMC Plant Biology, 2019
Background Exogenous 5-aminolevulinic acid (ALA) positively regulates plants chlorophyll synthesis and protects them against environmental stresses, although the protection mechanism is not fully clear. Here, we explored the effects of ALA on chlorophyll

Maternal nutrition as a key determinant of placental and developing blood–brain barrier xenobiotic protective functions

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Suboptimal maternal nutrition alters placental and developing blood–brain barrier (BBB) protective function and is associated with increased fetal brain vulnerability. In the placenta, nutritional adversity may reduce the exchange surface area and promote meta‐inflammation, compromising barrier efficiency in a model‐ and context ...

Transcriptome analysis reveals a positive effect of brassinosteroids on the photosynthetic capacity of wucai under low temperature

open access: yesBMC Genomics, 2019
Background Brassinosteroids (BRs) have a positive effect on many processes during plant growth and development, and in response to various abiotic stressors.

Sunlight‐Induced Lipid Oxidation and Degradation of Edible Oil Mediated by Hemoglobin: Implications for Food System Sustainability

open access: yesFood Science &Nutrition, Volume 14, Issue 10, October 2026.
Sunlight‐activated hemoglobin (Hb) functions as a robust natural biocatalyst that promotes the degradation of edible oils through a dual, synergistic pathway. Photo‐excitation of Hb triggers simultaneous energy transfer, generating singlet oxygen (1O2) and electron transfer, forming highly reactive ferryl (HbFe(IV)═O) species.

Determination of selected protoporphyrins in Parma ham with use of 5,10,15,20-tetra(4-hydroxyphenyl)porphyrin as a surrogate standard in the recovery study

open access: yesActa Chimica Slovenica, 2014
A high-performance liquid chromatographic analysis for the determination of hemin, protoporphyrin IX (PPIX), and zinc(II)protoporphyrin IX (Zn(II)PPIX) in Parmaham was developed.

Microbiome‐Derived Tryptophan Metabolites Regulate AhR Signaling to Restore Epithelial Barrier Integrity in Inflammatory Bowel Disease

open access: yesMicrobiologyOpen, Volume 15, Issue 5, October 2026.
The graphical abstract illustrates how microbiome‐derived indoles activate the aryl hydrocarbon receptor to restore the intestinal barrier. The picture contrasts the “leaky gut” state with the restored homeostasis achieved through AMPK, Nrf2, and IL‐22 signaling.

Unraveling the potential of zinc protoporphyrin-forming lactic acid bacteria for replacing nitrite and their role in quality characteristics of Harbin dry sausage

open access: yesFood Chemistry: X
This study evaluated the effects of zinc protoporphyrin-producing lactic acid bacteria specifically Weissella viridescens JX11, Weissella viridescens MDJ8, and Lactobacillus pentosus Q on nitrite substitution and the quality characteristics of Harbin dry

Persistence of PPO mutations and dynamics of Amaranthus palmeri resistance to PPO‐inhibitor herbicides in a decade

open access: yesPest Management Science, Volume 82, Issue 10, Page 10185-10191, October 2026.
Over a decade, Arkansas Amaranthus palmeri populations maintained resistance to PPO‐inhibiting herbicides. PPO2 mutations relate to shifts in herbicide resistance patterns over time. Abstract BACKGROUND Amaranthus is a highly troublesome weed genera globally.

Oxygen and Conformation Dependent Protein Oxidation and Aggregation by Porphyrins in Hepatocytes and Light-Exposed CellsSummary

open access: yesCellular and Molecular Gastroenterology and Hepatology, 2019
Background & Aims: Porphyrias are caused by porphyrin accumulation resulting from defects in the heme biosynthetic pathway that typically lead to photosensitivity and possible end-stage liver disease with an increased risk of hepatocellular carcinoma ...

Automated HPLC method for determining zinc protoporphyrin ix and protoporphyrin ix in erythrocytes of workers exposed to lead.

open access: yesSangyo Igaku, 1988
We developed an automated HPLC method for determining erythrocyte protoporphyrin. After a single extraction with N,N-dimethylformamide (DMF), zinc protoporphyrin IX (ZP) and protoporphyrin IX (PP) were separated by the column packed with a new type of reversed phase silica (capcell type) within 5 min. The column life was markedly extended to facilitate
