Cast‐Molded Channelized Hydrogel Scaffolds With Stereolithography‐Printed Templates

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Creating internal vascular networks within hydrogel scaffolds is crucial for providing the encapsulated cells with the necessary nutrients, oxygen, and metabolic exchange. Current methods for hydrogel scaffold fabrication face significant hurdles, including the challenge of forming sufficient internal channels, achieving precise scaffold ...

Phytochemical Investigation and Biological Evaluation of Disynaphia filifolia: A Novel Source of Tremetone in Asteraceae

Chemistry &Biodiversity, EarlyView.
ABSTRACT Chemical investigation of Disynaphia filifolia (Hassl.) R.M. King & H. Rob. (Asteraceae) led to the isolation of eight compounds, with tremetone being the major metabolite recovered. Tremetone has been suggested as the toxic compound in Ageratina altissima and Isocoma pluriflora, two species of the Asteraceae family. Although D.

New Terpenoids from Viguiera dentata: In Silico Pesticide‐Likeness Properties, Acetylcholinesterase Inhibition, Molecular Docking, and Evaluation against Spodoptera frugiperda

Chemistry &Biodiversity, EarlyView.
The chemical analysis of aerial parts of the melliferous Viguiera dentata led to the isolation of 20 substances, including the new cycloartanes 24‐epi‐argentatin C, 7β‐hydroxy‐24‐epi‐argentatin C, 7β‐hydroxy‐argentatin B. In‐combo results indicated that specific argentatins and ent‐kaurenoic acids have the potential to control Spodoptera frugiperda ...

Antinociceptive and Anti‐inflammatory Effect of Nicandrin B Isolated From Datura ferox in Zebrafish

Chemistry &Biodiversity, EarlyView.
ABSTRACT Nicandrin B (Nic B), a withanolide isolated from Datura ferox leaves, was investigated for its antinociceptive and anti‐inflammatory effects in adult zebrafish (Danio rerio). Animals treated with Nic B (4, 20, and 40 mg/kg) showed no toxicity and maintained normal locomotor activity.

Synthesis and Characterization of Dummy Template‐Based Molecularly Imprinted Polymers for Extraction of Aflatoxins in Food Samples

Chemistry &Biodiversity, EarlyView.
Five dummy templates and two functional monomers were systematically evaluated for the preparation of selective MIPs for aflatoxins. 5,7‐Dimethoxycoumarin and methacrylic acid were found to produce highly selective MIPs, and the adsorbent was characterized by FTIR, TGA, and SEM.
