Anterograde Signalling by Nitric Oxide: Characterisation and In Vitro Reconstitution of an Identified Nitrergic Synapse [PDF]

, 1998
Nitric oxide (NO) is recognized as a signaling molecule in the CNS where it is a candidate retrograde neurotransmitter. Here we provide direct evidence that NO mediates slow excitatory anterograde transmission between the NO synthase (NOS)-expressing B2 ...

How do parasites and predators choose their victim? A trade‐off between quality and vulnerability across antagonistic interactions

Biological Reviews, Volume 100, Issue 5, Page 2099-2115, October 2025.
ABSTRACT From blood‐sucking lice and food‐stealing gulls to pandemic‐inducing viruses and egg‐eating snakes: parasites and predators are ubiquitous in shaping ecology and evolution. Fundamental to these interactions is the way in which parasites and predators choose their victim. Here, I argue that a trade‐off between host quality and vulnerability can

Diplostomum‐Induced Sac Formation in Lenses of Ameiurus Bullheads: A Host Defence Response?

Journal of Fish Diseases, Volume 48, Issue 10, October 2025.
ABSTRACT Trematodes of the genus Diplostomum (Diplostomidae) are widely distributed and significant fish pathogens known for causing a range of negative effects. Any mechanism that protects the host from the parasite thus represents an evolutionary advantage.

Critical time window for NO-cGMP-dependent long-term memory formation after one-trial appetitive conditioning [PDF]

, 2002
The nitric oxide (NO)-cGMP signaling pathway is implicated in an increasing number of experimental models of plasticity. Here, in a behavioral analysis using one-trial appetitive associative conditioning, we show that there is an obligatory requirement ...

The Early Worm Catches the Bird? Productivity and Patterns of Trichobilharzia szidati Cercarial Emission from Lymnaea stagnalis

PLoS ONE, 2016
Digenean trematodes are common and abundant in aquatic habitats and their free-living larvae, the cercariae, have recently been recognized as important components of ecosystems in terms of comprising a significant proportion of biomass and in having a ...

Tolerance of organisms composing an Arctic kelp community to ocean warming and marine heatwaves

Journal of Ecology, Volume 113, Issue 8, Page 1938-1954, August 2025.
These results suggest that Arctic kelp communities are fairly tolerant to warming and short‐term marine heatwaves, despite the few minor effects on photosynthesis by some of the kelp species. We note that the future response of kelp communities must account for the potential indirect effects of climate change, such as predation and competition, along ...

The Dynamics of Contents of the Total Protein, Haemocyanin and Activity of the Antioxidant Enzymes Under Condition of Acute Hyperthermia in Pulmonate Mollusk Lymnaea stagnalis [PDF]

Journal of Stress Physiology & Biochemistry, 2018
The dynamics of total protein’s and hemocyanin’s content in the hemolymph, as well as the activity of the antioxidant enzymes (peroxidase, catalase and glutathione S-transferase) in pulmonate mollusc Lymnaea stagnalis (Linnaeus, 1758) under the impact of

The Antidepressant Sertraline Reduces Synaptic Transmission Efficacy and Synaptogenesis Between Identified Lymnaea Neurons

Frontiers in Marine Science, 2020
The incidence of depression among humans is growing worldwide, and so is the use of selective serotonin reuptake inhibitors (SSRIs), such as sertraline hydrochloride.

Общая характеристика популяционного состава клеток гемолимфы моллюсков Lymnaea stagnalis (Gastropoda, Lymnaeidae)

Амурский зоологический журнал
Изучен клеточный состав гемолимфы лёгочных моллюсков Lymnaea stagnalis. На основании результатов световой, сканирующей электронной микроскопии и проточной цитометрии в гемолимфе выделены две функционально активные популяции клеток (гиалиноциты и ...
