Mitotic Chromosome Preparations of Freshwater Stingrays

, 2015
The technique for obtaining mitotic chromosomes proposed by Foresti et al. (1981) when applied in freshwater stingrays didn’t result in good quality chromosome preparations. Only a few studies have used this technique to obtain good quality chromosomes in this fi sh group (Valentim et al. 2006; Cruz et al. 2011).

Stingray venom activates IL-33 producing cardiomyocytes, but not mast cell, to promote acute neutrophil-mediated injury

Scientific Reports, 2017
One of the hallmarks of acute inflammation is neutrophil infiltration of tissues. We investigated molecular mechanisms implicated in acute neutrophilic inflammation induced by the venom of a freshwater stingray (Potamotrygon cf. henlei) in mice.

Monitoring Biogenic Amines: Comparative Assessment of Detection Methods for Key Market Marine and Freshwater Species

Journal of Food Science, Volume 91, Issue 5, May 2026.
ABSTRACT Biogenic amines, primarily histamine, cadaverine, and putrescine, are important indicators of microbial spoilage and potential health risks. This review summarizes established and novel analytical methods for quantitatively determining biogenic amines in fish and fish products, along with their limits of detection in these complex matrices ...

Brain Morphology and Quantitative Assessment of Sensory Brain Areas in Southern Bluefin Tuna, Thunnus maccoyii (Scombridae, Teleostei)

Journal of Comparative Neurology, Volume 534, Issue 4, April 2026.
The absolute and relative volume of major sensory and integrative brain regions of the southern bluefin tuna Thunnus maccoyii are examined using magnetic resonance imaging (MRI). A dominant cerebellum projects into the midbrain ventricular space, while the optic tectum represents a smaller proportion of total brain volume than previously estimated ...
