Synergistic effect of ZIF‐8 nanomaterial on 2,4‐D efficacy by regulating auxin synthesis pathway in barnyard grass [Echinochloa crus‐galli (L.) P. Beauv.]

open access: yesNew Plant Protection, Volume 2, Issue 4, December 2025.
ZIF‐8 exhibited a synergistic effect on 2,4‐D efficacy against barnyard grass by regulation of auxin synthesis pathway, as well as the synergistic regulation of metabolic pathways involving 2,4‐D and ZIF‐8. Furthermore, the use of ZIF‐8 as a carrier could improve the safety of 2,4‐D for wheat.

The inhibitor of calcium activated neutral proteinase is an anti-meiotic agent. The spermicidal and anti-viral action [PDF]

open access: yes, 1995
In situ cytogenetic morphology and analysis showed that Epstein-Barr Virus (EBV)-infected Raji and EBV-producing P3HR-1 cells divide by meiosis and follow the life cycle of malignant cells in vitro. Meiosis was documented by the presence of condensed

μ-calpain binds to lipid bilayers via the exposed hydrophobic surface of its Ca2+-activated conformation [PDF]

open access: yes, 2006
μ- and m-calpain are cysteine proteases requiring micro- and millimolar Ca2+ concentrations for their activation in vitro. Among other mechanisms, interaction of calpains with membrane phospholipids has been proposed to facilitate their activation by ...

Regulation of Dopamine Uptake by Vasoactive Peptides in the Kidney

open access: yesScientifica, 2016
Considering the key role of renal dopamine in tubular sodium handling, we hypothesized that c-type natriuretic peptide (CNP) and Ang-(1-7) may regulate renal dopamine availability in tubular cells, contributing to Na+, K+-ATPase inhibition.
