Applications and advancements in animal models for antiviral research on mosquito‐borne arboviruses

Animal Models and Experimental Medicine, Volume 7, Issue 5, Page 673-684, October 2024.
Animal models are crucial in antiviral research on mosquito‐borne arboviruses, playing a role in understanding disease mechanisms, vaccine development, and toxicity testing. The use of animal models confronts hurdles related to ethical considerations and the successful translation of findings from animals to humans.

Nutrient conditions influence allelopathic capabilities of Ludwigia adscendens and other tropical macrophytes against Microcystis aeruginosa

Freshwater Biology, Volume 69, Issue 4, Page 538-555, April 2024.
Abstract Macrophytes may release allelochemicals that suppress competing phytoplankton, although it is unclear how their effectiveness could be influenced by environmental nutrient conditions. To approach this, we conducted a series of bioassays against the bloom‐forming cyanobacterium Microcystis aeruginosa using extracts and exudates from potentially

High intraspecific variability and previous experience affect polyphenol metabolism in polyphagous Lymantria mathura caterpillars

Ecology and Evolution, Volume 14, Issue 2, February 2024.
We studied polyphenol metabolism in polyphagous caterpillars of Lymantria mathura (Erebidae, Lepidoptera) to explore mechanisms that may contribute to its ability to feed on various host‐plants. We detected pronounced intraspecific variation in polyphenol metabolism, an ability to excrete ingested metabolites and potential dietary habituation.

Elaeocarpusin, a proto-type of geraniin from Geranium thunbergii.

Chemical and Pharmaceutical Bulletin, 1986
The co-occurrence of geraniin (2) and a novel ellagitannin, elaeocarpusin (1) in Geranium thunbergii has been demonstrated. In addition, enzymatic transformation of 1 into 2 has been achieved, leading to the evidence that dehydroascorbic acid (4) participates as a co-enzyme in the oxidative metabolism of the hexahydroxydiphenoyl group to the ...
