Glabralysins, potential New β-pore-forming toxin family members from the schistosomiasis vector snail biomphalaria glabrata [PDF]

, 2020
Biomphalaria glabrata is a freshwater Planorbidae snail. In its environment, this mollusk faces numerous microorganisms or pathogens, and has developed sophisticated innate immune mechanisms to survive.

Evaluation of bigano snail (Stramonita haemastoma) as a seafood resource

Journal of the World Aquaculture Society, Volume 56, Issue 3, June 2025.
Abstract Bigano snail, Stramonita haemastoma, commonly known as oyster drill or red‐mouthed rock whelks, has gained growing interest as a potential seafood product. However, to date, there is a notable lack of preliminary evaluation regarding its commercial viability.

Chemotactic Responses of Oscheius myriophilus to Mollusk Mucus

Agronomy
Terrestrial slugs and snails can significantly harm agriculture. Due to environmental concerns associated with chemical molluscicides, biological control methods are increasingly being explored.

Mechanical properties and cuticle organisation in mandibles are related to the task specialisation in leafcutter ants (Atta laevigata, Attini, Formicidae)

Physiological Entomology, Volume 50, Issue 2, Page 152-165, June 2025.
Task‐specialization and mandible properties: Leafcutter ants show caste‐based task division, reflected in mandible morphology and mechanical properties. Structural and mechanical analysis: The cuticle was composed of exo‐, meso‐, and endocuticle.

Circadian Rhythms of Crawling and Swimming in the Nudibranch Mollusc Melibe leonina [PDF]

, 2014
Daily rhythms of activity driven by circadian clocks are expressed by many organisms, including molluscs. We initiated this study, with the nudibranch Melibe leonina, with four goals in mind: (1) determine which behaviors are expressed with a daily ...

Bivalve Shell Utilization by Juvenile Octopus vulgaris in Sandy Substrates

Ecology and Evolution, Volume 15, Issue 5, May 2025.
This study investigates how juvenile Octopus vulgaris adapt to sandy environments with limited shelter and high predation risk by using empty bivalve shells for protection. Through four SCUBA expeditions in NW Spain, nine juveniles were observed using shells that fit their body size, strategically positioning themselves for surveillance and employing ...

Assessing brain neuroplasticity: Surface morphometric analysis of cortical changes induced by Quadrato motor training

Journal of Anatomy, Volume 246, Issue 5, Page 757-769, May 2025.
Morphological markers for brain plasticity are still lacking, and their findings are challenged by cortical brain surface variability. To overcome the “correspondence problem,” we used a landmark‐free method (generalized Procrustes surface analysis, GPSA) to investigate cortical surface shape variation in healthy volunteers practicing Quadrato motor ...

Species‐specific diatom dynamics shape their vertical distribution and export during bloom decline

Limnology and Oceanography, Volume 70, Issue 4, Page 959-976, April 2025.
Abstract The Southern Ocean is a critical region for global biogeochemical cycles, particularly for carbon dioxide uptake and organic carbon export, partly driven by extensive phytoplankton blooms. In naturally iron‐fertilized regions of this otherwise iron‐limited ocean, these blooms are primarily driven by diatoms. Variability in bloom occurrences on

FISH, a new tool for in situ preservation of RNA in tissues of deep‐sea mobile fauna

Limnology and Oceanography: Methods, Volume 23, Issue 4, Page 273-292, April 2025.
ABSTRACT Accessing the metabolic functioning of deep‐sea animals in situ remains a technological challenge as the recovery time of samples is incompatible with the short lifespan of such molecules as mRNAs. Tools able to preserve RNA in situ exist, but they are incompatible with the study of mobile fauna.

Genotoxikus hatásra bekövetkező funkcionális és strukturális DNS változások = Functional and structural changes in DNA upon genotoxic effects [PDF]

, 2008
Morfológiai és biokémiai vizsgálataink arra utalnak, hogy a a genotoxikus hatások kategorizálhatók az okozott kromatin változások alapján. A kemotoxikus változások potenciális diagnosztikus jelentősége miatt vizsgáltuk a nehézfémek (elsősosrban kadmium) (
