Angelica dahurica Polysaccharides Ameliorate Colitis by Reducing the Restriction of Gut Microbiota‐Derived Imidazole Propionate on PPAR‐γ Signaling Activation

Phytotherapy Research, EarlyView.
ABSTRACT Angelica dahurica radix (ADR), the root of the botanical family Apiaceae (genus Angelica, species Angelica dahurica (Hoffm.)), has been used to treat colitis in clinical practice. The immunomodulatory effects of ADR are attributed to its polysaccharides (RP). However, its mechanism of action has not been elucidated.

Pyrene‐diaminomaleonitrile‐based fluorescent probe for the turn‐on detection and bioimaging of hypochlorite

Responsive Materials, EarlyView.
We prepared a “turn‐on” fluorescent probe Py‐DA for high‐performance recognition of HClO/ClO− at room temperature, which exhibits fast response rates (<5 s), excellent selectivity, strong anti‐interference capabilities, superior sensitivity, and low detection limits (37.8 nM). Convenient rapid visual smartphone identification and fluorescent imaging in

An Amalgamation Nim with Restriction [PDF]

arXiv
In an amalgamation Nim, players are allowed to use a move from the traditional form of Nim or to amalgamate two piles when they are not empty. No formula that describes the set of P-positions of Amalgamation Nim is known. The author gives a condition on the amalgamation of two piles.

Chemically‐Linked Heterostructures of Palladium Nanosheets and 2H‐MoS2

Small, EarlyView.
The photoresponse of MoS2 devices is extended to the near‐infrared region (up to 1700 nm) through chemical connection to Pd nanosheets (PdNS). A maleimide is used for covalent connection to MoS2, and a phenyl bromide moiety for linkage to the PdNS. In the absence of the chemical linker, van der Waals heterostructures show poorer enhancement of the ...
