Die Chemie und Biologie der Tetrodotoxin Naturstofffamilie

open access: yesAngewandte Chemie, Volume 137, Issue 35, August 25, 2025.
Tetrodotoxin ist vor allem als das Gift des Kugelfisches bekannt, einer Delikatesse in der japanischen Küche. Seine Toxizität beruht auf der selektiven Blockade von NaV Kanälen, wie am Beispiel der NaV1.7 Pore dargestellt, wobei das DEKA Motiv hervorgehoben ist, das für die Durchlässigkeit von Natriumionen verantwortlich ist.

Using Stable Isotopes to Assign Origin of White‐Chinned Petrels Killed by Longline Fisheries

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 7, July 2025.
ABSTRACT Incidental capture (bycatch) of seabirds in longline and trawl fisheries is one of the main threats to many albatrosses and large petrels. The White‐chinned Petrel (Procellaria aequinoctialis) has a circumpolar distribution and is the seabird species killed most frequently by fisheries in the Southern Ocean.

Coupling Genetic and Demographic Data to Reveal Dispersal Processes in Emperor Penguins

open access: yesEcology and Evolution, Volume 15, Issue 5, May 2025.
Dispersal is ubiquitous but dispersal rates, range, and behaviors remain difficult to measure. By developing new models combing demographic and genetic data, we propose to unravel species dispersal behaviors and apply our methodology to the emperor penguins, living in the most remote place on earth where measurements of dispersal are nonexistent.

Combination of Different Methods, Including Image Analysis, to Define the Fibrous Structure of High‐Moisture Extrusion‐Cooking Extrudates

open access: yesJournal of Texture Studies, Volume 56, Issue 2, April 2025.
Extrudate is fibrous with an anisotropy index of more than 1 and no break during the lamellarity test. Different types of fibration are then possible, from high to low lamellarity. The intermediate state was for extrudates with 25/75 or 50/50 wheat gluten/soy protein concentrate.
