Kaempferol Protects Intestinal Health in Chinese Forest Musk Deer Possibly by Regulating Intestinal Microbiota and Inhibiting the NF‐κB/NLRP3 Signaling Pathway

Integrative Zoology, EarlyView.
Kaempferol modulates the tryptophan metabolism pathway by increasing the abundances of Christensenellaceae R7 group, Bacteroides, and Blautia and reducing that of Rikenellaceae RC9 gut group, thereby significantly increasing the levels of ILA and IAA. This process inhibits the activation of NF‐κB/NLRP3 signaling pathway, reduces pro‐inflammatory factor

The mediating role of the kynurenine pathway in longitudinal associations between dietary intake and quality of life in colorectal cancer survivors up to 12 months posttreatment

International Journal of Cancer, Volume 159, Issue 1, Page 122-143, 1 July 2026.
What's New? Many colorectal cancer survivors experience reduced health‐related quality of life (HRQoL), often lasting years after diagnosis. Healthy dietary patterns and even individual macro‐ and micronutrients, however, can potentially improve HRQoL.

Structure‐Guided Surface Engineering of an Artificial Metallolyase for Highly Enantioselective Michael Addition

ChemCatChem, Volume 18, Issue 11, 15 June 2026.
X‐ray visualization of copper‐binding modes revealed nonspecific surface metal sites that compromise stereoselectivity. Structure‐guided mutations suppressed background reactivity and enabled precise enantioselective control in the Michael addition, delivering up to 99% ee.

Chronic Low‐Dose Unsymmetrical Dimethylhydrazine Exposure in Rats: Multiorgan Mechanisms and Biomarker Identification

Journal of Applied Toxicology, Volume 46, Issue 6, Page 1987-2002, June 2026.
ABSTRACT Unsymmetrical dimethylhydrazine (UDMH), a highly toxic rocket propellant with known multiorgan effects, requires urgent characterization of its chronic low‐dose toxicity. Using an integrated approach including exploratory transcriptomics (n = 3/group) and metabolomic (n = 4/group) approaches in male Sprague–Dawley rats exposed to high‐dose ...

4-(Dimethylamino)pyridinium tetrachlorido(pyridine-2-carboxylato-&#954;2N,O)stannate(IV)

Acta Crystallographica Section E, 2012
The reaction of 4-(dimethylamino)pyridine, picolinic acid and stannic chloride yields the title salt, (C7H11N2)[SnCl4(C6H4NO2)], in which the SnIV atom is N,O-chelated by the picolinate ion in a cis-SnNOCl4 octahedral geometry.
