Percutaneous Retinoid Absorption and Embryotoxicity

open access: yesJournal of Investigative Dermatology, 1990
A single application of 17 micrograms/kg or 8.7 mg/kg all-trans-[10,11-3H2]-retinoic acid dissolved in acetone to shaved dorsal hamster skin resulted in rapid absorption and dose-dependent rates of elimination. An equation describing a two-compartment open model with a very brief lag time and first-order uptake and elimination was used to describe the ...

Isolation, Structural Elucidation, and Anti‐Melanogenic Activity of a Novel Pectic Polysaccharide From Alhagi camelorum Fisch

open access: yesChemistry &Biodiversity, Volume 23, Issue 11, November 2026.
Polysaccharide extraction from Alhagi camelorum Fisch. was optimized, yielding ACP‐II‐1, a novel GalA‐rich, HG‐dominant pectin (26.145 kDa) containing branched RG‐I domains. ACP‐II‐1 reduced melanogenesis in forskolin‐stimulated B16F10 cells and a zebrafish model.

Reduction in paraquat embryotoxicity by ascorbic acid in Xenopus laevis

open access: yes, 2001
The toxicity of herbicide Paraquat (PQ, 1-1'-dimethyl-4,4'bipyridylium dichloride) in animal cells is related to its rapid reduction and instantaneous reoxidation to produce the reactive oxygen species.

A Waterfowl Reproduction Model to Predict Carryover Effects of Oil Spills

open access: yesEcology and Evolution, Volume 16, Issue 11, November 2026.
For wintering and migrating birds, contamination from oil and other substances may delay arrival on the breeding grounds and lead to lower body mass upon arrival. These delays and losses of body mass could lead to smaller clutch sizes and lower propensity to renest.

Animal models of anemia of inflammation: Methodological advances, limitations, and translational applications

open access: yesAnimal Models and Experimental Medicine, Volume 9, Issue 10, Page 1982-2000, October 2026.
Anemia of inflammation is a highly prevalent secondary anemia complicating chronic inflammatory diseases. Current animal models are categorized into sterile inflammation, disease‐specific, and genetically engineered models, with comparative analysis of their modeling principles, characteristic phenotypes, and translational advantages to elucidate core ...
