α/β Hydrolases: Toward Unraveling Entangled Classification

open access: yesProteins: Structure, Function, and Bioinformatics, Volume 93, Issue 4, Page 855-870, April 2025.
ABSTRACT α/β Hydrolase‐like enzymes form a large and functionally diverse superfamily of proteins. Despite retaining a conserved structural core consisting of an eight‐stranded, central β‐sheet flanked with six α‐helices, they display a modular architecture allowing them to perform a variety of functions, like esterases, lipases, peptidases, epoxidases,

Does Variation of the Inter-Domain Linker Sequence Modulate the Metal Binding Behaviour of Helix pomatia Cd-Metallothionein? [PDF]

open access: yes, 2016
Snail metallothioneins (MTs) constitute an ideal model to study structure/function relationships in these metal-binding polypeptides. Helix pomatia harbours three MT isoforms: the highly specific CdMT and CuMT, and an unspecific Cd/CuMT, which represent ...

Sedimentology and palaeoenvironmental analysis of a karstic shallow carbonate lake (Early‐Middle Miocene, Sinj Basin, Croatia)

open access: yesThe Depositional Record, Volume 11, Issue 1, Page 121-146, February 2025.
Miocene karstic Lake Sinj. A prograding carbonate bench on a gently inclined lake margin showing shallowing upwards tendency, and closing of the lake. Abstract In the Early to Middle Miocene, the post‐orogenic intramontane lacustrine Sinj Basin that belonged to the Dinarides Lake System evolved in the area of the External Dinarides.

Distribution of heavy metal concentrations in the different soft and hard tissues of tropical mud-flat snail telescopium telescopium (Family: Potamididae) collected from Sepang Besar River [PDF]

open access: yes, 2012
The concentrations of Cd, Cu, Pb, Fe, Ni and Zn were determined in the different parts of the soft tissues (foot, cephalic tentacle, mantle, muscle, gill, digestive caecum and remaining soft tissues) and three parts of hard tissues or shells (anterior ...

Morphology of the unique egg cases of hornsharks (Heterodontiformes: Heterodontidae)

open access: yesJournal of Fish Biology, Volume 106, Issue 2, Page 389-402, February 2025.
Abstract Many of the egg cases of oviparous chondrichthyans remain unknown and undescribed in the literature. Egg cases can be a useful taxonomic character for species distinction and can be a valuable indicator of a species distribution in the field.

Genetic diversity in fishery-exploited populations of the banded murex ("Hexaplex trunculus") from the southern Iberian Peninsula [PDF]

open access: yes, 2008
[Abstract] This study presents an analysis of the genetic diversity in Hexaplex trunculus from three localities of the southern Iberian Peninsula (Ria Formosa and Ria de Alvor in Portugal, and Río Piedras in Spain) using three mitochondrial (12S rRNA ...

Eocene gastropods of the New Forest, UK

open access: yesGeology Today, Volume 41, Issue 1, Page 26-37, January/February 2025.
Gastropods expanded into niches vacated by both terrestrial and marine organisms following the end‐Cretaceous mass extinction, to become one of the dominant mollusc groups of the Cenozoic. The Selsey Formation of Eocene age was deposited within a shallow marine embayment across the Hampshire Basin (southern England) and contains a particularly diverse ...

Radiocarbon Ecology of the Land Snail Helix Melanostoma in Northeastern Libya [PDF]

open access: yes, 2017
Terrestrial gastropods are problematical for radiocarbon (14C) measurement because they tend to incorporate carbon from ancient sources as a result of their dietary behavior.

Neuronal background of positioning of the posterior tentacles in the snail Helix pomatia [PDF]

open access: yes, 2013
The location of cerebral neurons innervating the three recently described flexor muscles involved in the orientation of the posterior tentacles as well as their innervation patterns were investigated, applying parallel retrograde Co- and Ni-lysine as ...
