Ecological Research, Volume 41, Issue 5, September 2026.Potentially toxic metal(loid)s (PTMs) bioaccumulated across a plant‐herbivore‐predator food chain. Irrespective of soil concentrations, female crickets actively selected PTM‐enriched leaves, while predatory mantids showed no developmental impairment. Trophic transfer of PTMs was rather influenced more by a function of intrinsic species traits than by ...

Identification of tetrodotoxin and fish species in an adulterated dried mullet roe implicated in food poisoning [PDF]
, 2010 [[abstract]]There was 1 victim of neurotoxic food poisoning from an adulterated dried mullet roe in Kaohsiung, Taiwan, in March 2001. The victim exhibited typical neurotoxic symptoms. The residue of dried mullet roe retained by the victim was assayed for

European Journal of Neuroscience, Volume 64, Issue 5, September 2026.A jugular/nodose ganglion–brainstem slice culture with intact ganglia attached to the brainstem, preserving functional vagal afferent pathways to the brainstem. In this preparation, cholecystokinin activates brainstem neurons, central vagal terminals and brainstem astrocytes, establishing this preparation as a powerful model for dissecting the neuro ...

Studies on Toxin-Producing Ability and Gene Map of Tetrodotoxin- Producing Bacteria
, 2010 [[abstract]]Tetrodotoxin (TTX) is one of the best known marine toxins, because of it’s an extremely potent, low-molecular weight, and non-protein neurotoxin. TTX exists with its several analogs.

Expression of tetrodotoxin-sensitive and resistant sodium channels by rat melanotrophs
, 2004 International audienceRat melanotrophs fire Na+ and Ca2(+)-dependent action potentials. Whereas the molecular identity of Ca2+ channels expressed by these cells is well documented, less is known about Na channels.

Journal of Neurochemistry, Volume 170, Issue 9, September 2026.In this article, Hannett and colleagues investigate extracellular vesicles (EVs) secreted by neurons, small membrane‐bound organelles that transmit information among cells. They found that EVs are mainly uptaken by target neurons via a mechanism dependent on the membrane scission protein Dynamin.

Journal of Neuroendocrinology, Volume 38, Issue 9, September 2026.Abstract Pulsatile gonadotropin‐releasing hormone (GnRH) and luteinizing hormone (LH) secretion are essential for reproductive function and are thought to be governed by arcuate nucleus kisspeptin Kiss1ARH neurons via neurokinin B (NKB) signaling through TacR3.

Electrostatic tuning of NaV channel activation by the domain II S3–S4 extracellular loop
The Journal of Physiology, Volume 604, Issue 17, Page 7210-7224, 1 September 2026.Abstract figure legend Voltage‐gated sodium (NaV) channels are critical for electrical signalling, yet the molecular determinants that tune isoform‐specific activation remain incompletely understood. Here, we show that charged amino acids in the extracellular DII S3–S4 loop of NaV1.7 play a key role in setting voltage‐dependent activation.
