New insights into epileptic spasm generation and treatment from the TTX animal model

Epilepsia Open, EarlyView.
Abstract Currently, we have an incomplete understanding of the mechanisms underlying infantile epileptic spasms syndrome (IESS). However, over the past decade, significant efforts have been made to develop IESS animal models to provide much‐needed mechanistic information for therapy development.

New Invasive Nemertean Species (Cephalothrix Simula) in England with High Levels of Tetrodotoxin and a Microbiome Linked to Toxin Metabolism

Marine Drugs, 2018
The marine nemertean Cephalothrix simula originates from the Pacific Ocean but in recent years has been discovered in northern Europe. The species has been associated with high levels of the marine neurotoxin Tetrodotoxin, traditionally associated with ...

Prenatal betamethasone–postnatal N‐methyl‐D‐aspartic acid model of spasms: Update on mechanisms and treatments

Epilepsia Open, EarlyView.
Abstract Infantile epilepsy spasms syndrome (IESS), formerly known as infantile spasms or West Syndrome, is a severe epilepsy syndrome affecting about 3 in 10,000 newborns in the United States. Characterized by clusters of epileptic spasms, interictal hypsarrhythmia, and developmental delays, IESS has diverse causes, including structural‐metabolic ...

Nervous System and Gastrointestinal Effects of the Insecticide Esfenvalerate on the Rat: An Ex Vivo Study [PDF]

, 2014
Esfenvalerate belongs to the pyrethroid group of insecticides which display significant selective toxicity against insects compared to mammalian species, nevertheless, they may pose health risks, especially in case of accidental exposure.

The multiple hit model of infantile and epileptic spasms: The 2025 update

Epilepsia Open, EarlyView.
Abstract Objective Infantile and epileptic spasms syndrome (IESS) is a developmental and epileptic encephalopathy manifesting with epileptic spasms and poor neurodevelopmental outcomes. There is an urgent need for the development of more effective and tolerated therapies.

NMR structure of μ-conotoxin GIIIC : leucine 18 induces local repacking of the N-terminus resulting in reduced NaV channel potency [PDF]

, 2018
mu-Conotoxins are potent and highly specific peptide blockers of voltage-gated sodium channels. In this study, the solution structure of mu-conotoxin GIIIC was determined using 2D NMR spectroscopy and simulated annealing calculations.

Ketogenic diet for infantile epileptic spasms

Epilepsia Open, EarlyView.
Abstract Approximately half of all cases of Infantile Epileptic Spasms Syndrome (IESS) do not respond to vigabatrin and hormonal therapies. There is no clear consensus as to the second‐line therapy for IESS. Ketogenic diet (KD) has emerged as an effective treatment for certain drug‐resistant epilepsies and in many cases of IESS.

A chemical genetic approach reveals distinct EphB signaling mechanisms during brain development. [PDF]

, 2012
EphB receptor tyrosine kinases control multiple steps in nervous system development. However, it remains unclear whether EphBs regulate these different developmental processes directly or indirectly.

Differential segment‐specific signalling pathways for guanylate cyclase C‐activated anion secretion in murine ileocolon

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Guanylate cyclase‐C (GC‐C) is the receptor for endogenous (uro)guanylin peptides, bacterial toxins and pharmacological analogues. Receptor activation leads to intestinal fluid loss, but also activates an antiproliferative pathway and is a promising target in colorectal cancer therapy.

Basic aspects of the pharmacodynamics of tolperisone, a widely applicable centrally acting muscle relaxant [PDF]

, 2014
Tolperisone (2-methyl-1-(4-methylphenyl)-3-piperidin-1-ylpropan-1-one hydro-chloride) was introduced in the clinical practice more than forty years ago and is still evaluated as a widely applicable compound in pathologically elevated skeletal muscle tone
