Genotoxicity of Nicotiana tabacum leaves on Helix aspersa [PDF]

Genetics and Molecular Biology, 2013
Tobacco farmers are routinely exposed to complex mixtures of inorganic and organic chemicals present in tobacco leaves. In this study, we examined the genotoxicity of tobacco leaves in the snail Helix aspersa as a measure of the risk to human health. DNA

<i>Marchantia polymorpha</i> Defense Against Snail Herbivory. [PDF]

Plant Environ Interact
Ancestral liverwort species were already equipped with the jasmonate pathway to fend off herbivores. However, insect appearance on earth does not fit with the estimated age of bryophytes, as they probably evolved million years later. We found that the snail Helix aspersa readily feeds on Marchantia polymorpha and that a Mpcoi1 mutant, where the ...

Safety of HelixComplex snail mucus (HSM) as a novel food pursuant to Regulation (EU) 2015/2283. [PDF]

EFSA J
Abstract Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver an opinion on HelixComplex Snail Mucus (HSM) as a novel food (NF) pursuant to Regulation (EU) 2015/2283. The NF consists of snail mucus collected from Helix aspersa maxima and is proposed to be used by adults

Investigating the inhibitory effects of carotenoids‐fortified Helix aspersa slime on oxidative stress, collagenase and tyrosinase enzyme activities

Journal of Cosmetic Dermatology
Abstract Background The investigations of snail slime and its possible biological activities have been performed recently. Aim This study aimed to evaluate the properties of Helix aspersa snail slime (HAS), and carotenoids‐fortified slime (HASC). Methods Snails were fed with carrots for 10 days. Slime was collected and extracted using water.

Are rare plant species less resistant than common ones to herbivores? A multi‐plant species study using above‐ and below‐ground generalist herbivores

Ecology and Evolution, Volume 13, Issue 9, September 2023., 2023
In our multi‐herbivore and multi‐plant species experiment, we address the link between plant resistance to herbivores and their local and regional rarity by putting it into context with their life‐history traits, habitats and evolutionary history. We found that rare plant species are not less resistant to herbivores than common ones.

Neuropeptides and degenerin/epithelial Na+ channels: a relationship from mammals to cnidarians

The Journal of Physiology, Volume 601, Issue 9, Page 1583-1595, 1 May 2023., 2023
Abstract figure legend Several degenerin (DEG)/epithelial Na+ channel (ENaC) ion channels interact with neuropeptides. Some DEG/ENaCs from vertebrates, including humans, are modulated by neuropeptides, whereas others, from bilaterian invertebrates and cnidarians, are directly activated by them. For modulation, neuropeptides [here, RFamides (RFa)] bind,
