System-wide targeted analysis of oxylipins and lipoproteins in chronic peripheral neuropathic pain-an explorative study. Open
These results present a previously unexplored network of integrated alterations of lipoproteins, octadecanoids, and cytokines in patients suffering from NeuP, indicative of deviant immuno-protective functioning across several biological sy…

Biological Control of Ca-Carbonate Crystal Microstructure and Texture: Adapting Crystal Morphology, Orientation, and Arrangement to Biomaterial Function Open
The mineralized cover of chiton (Polyplacophora) soft tissue consists of aragonite, developed as shell-plates, girdle-scales, and girdle-spicules. This study characterizes crystallographic aspects of the girdle-spicules of the species Isch…

The Diversity of Crystals, Microstructures and Texture That Form Ostreoidea Shells Open
The shells of bivalved molluscs comprise, in general, few microstructures and very few textures. In the case of ostreoid oysters, a high diversity has been observed. The shells consist of columnar-prismatic, foliated, granular calcite and …

The Textural Motif of Foliated Calcite in Ostreoidea (Mollusca) Open
The microstructure of bivalve foliated calcite is extraordinary. It consists of units formed of stacks of folia with individual folia consisting of arrowhead-ended crystal laths. We investigated the texture of the foliated microstructure, …

The Diversity of Crystals, Microstructures and Texture That Form Ostreoidea Shells Open
The shell of Ostreoidea is specific among that of bivalves, as it comprises many crystal microstructures and crystal textures. This stems from the fact that into the basic shell structure, consisting of columnar, foliated, granular calcite…

Oyster shells as archives of present and past environmental variability and life history traits: A multi‐disciplinary review of sclerochronology methods and applications Open
Oysters inhabit a variety of coastal and deep‐sea settings over a wide latitudinal range and have a role as ecosystem engineers. They also represent an important food source for humans since hunter‐gatherer times, which motivates interest …

Organic macromolecules transport a significant proportion of the calcium precursor for nacre formation Open
The mechanism of nacre formation in gastropods involves a vesicular system that transports organic and mineral precursors from the mantle epithelium to the mineralization chamber. Between them lies the surface membrane, a thick organic str…

Microstructures, crystallography and growth patterns of serpulid tubeworms (Class Polychaeta) Open
Serpulid polychaetes are marine worms that secrete calcium carbonate tubes in which they live. Despite extensive previous
\nresearch on their microstructures, there are no crystallographic data and their biomineralization process remains u…

The Biological Crystals in Chamid Bivalve Shells: Diversity in Morphology and Crystal Arrangement Pattern Open
Chamid bivalves are marine organisms that live in high-energy environments and are cemented to hard substrates. To avoid shell damage, the organisms form thick, densely ornamented shells. Shell material consists of aragonite, and the ornam…

Microstructures, crystallography and growth patterns of serpulid tubeworms (Class Polychaeta) Open
Serpulid polychaetes are global marine worms that secrete tubes of calcium carbonate, in which they live. Despite extensive previous research on their microstructures, there are no crystallographic data and their biomineralization process …

Crystal organisation and material properties of Chama and Glycymeris myostraca and shells Open
Movement of bivalve hard and soft tissue requires muscular action. Despite diverse bivalve lifestyles and living environments, the myostracum, a specific hard tissue formed where muscles attach to the shell, appears similar in structure fo…

Guinea fowl eggshell structural analysis at different scales reveals how organic matrix induces microstructural shifts that enhance its mechanical properties Open
Guinea fowl eggshells have an unusual structural arrangement that is different from that of most birds, consisting of two distinct layers with different microstructures. This bilayered organization, and distinct microstructural characteris…

Organization and Formation of the Crossed-Foliated Biomineral Microstructure of Limpet Shells Open
To construct their shells, molluscs are able to produce a large array of calcified materials including granular, prismatic, lamellar, fibrous, foliated, and plywood-like microstructures. The latter includes an aragonitic (the crossed-lamel…
