Electroenzymatic Cascades for Nitrogen Upgrading: Beyond Ammonia Towards Value‐Added Nitrogen Chemicals

open access: yesChemCatChem, Volume 18, Issue 7, 14 April 2026.
This review maps how electroenzymatic cascades that couple nitrogen‐cycle enzymes with C─N bond forming auxilary enzymes, powered by direct electron transfer (DET) or mediated electron transfer (MET), can upgrade N2 and waste nitrogen streams into value‐added amines, amides, amino acids, and other nitrogen‐based chemicals.

Reprogramming SREBP1‐dependent lipogenesis and inflammation in high‐risk breast with licochalcone A: A novel path to cancer prevention

open access: yesInternational Journal of Cancer, Volume 158, Issue 7, Page 1927-1940, 1 April 2026.
What's new? Endocrine drugs repurposed from treatment protocols are the primary medications available for breast cancer (BC) prevention in at‐risk women. Adverse effects, however, significantly minimize uptake and prevention impact. Here, the authors investigated licochalcone A (LicA), a non‐endocrine anti‐inflammatory agent with reported hematologic ...

Two stable gut microbiome guilds predict liver tumor class and treatment responses

open access: yesiMeta, Volume 5, Issue 2, April 2026.
Gut microbiome alterations are linked to hepatocellular carcinoma (HCC), yet taxon‐based biomarkers often lack reproducibility. Using shotgun metagenomics from 120 resectable HCC (MT) and 76 benign hepatic tumor controls (BT), we reconstructed a stable interaction‐based Two Competing Guilds model (HCC‐TCG) comprising 142 genomes organized into two ...

Folic acid and the methylation of homocysteine by Bacillus subtilis [PDF]

open access: yes, 1972
1. Cell-free extracts of Bacillus subtilis synthesize methionine from serine and homocysteine without added folate. The endogenous folate may be replaced by tetrahydropteroyltriglutamate or an extract of heated Escherichia coli for the overall C1 ...

Role of biopterin transporter (BT1) gene on growth and infectivity of Leishmania [PDF]

open access: yes, 2007
Leishmania are known to be auxotrophic for pteridines that are known to play a critical role in the parasites survival. In the present work the role of biopterin transporter in the growth of the parasite and infectivity in to macrophages has been worked ...
