The Chemistry and Biology of the Tetrodotoxin Natural Product Family

open access: yesAngewandte Chemie International Edition, Accepted Article.
Tetrodotoxin is a neurotoxic marine alkaloid, first isolated in 1909 from pufferfish and named after the biological order tetraodontiformes. Since its structural elucidation in 1964, it has attracted the interest of synthetic organic chemists due to its exceptional polarity, complex architecture, and important biological activity.

Intestinal responses in pacu (Piaractus mesopotamicus) exposed to fasting and refeeding nutritional management

open access: yesThe Anatomical Record, EarlyView.
Abstract Fasting is a practice in the aquaculture industry that aims to reduce feed costs. This practice can affect the gastrointestinal system of fish. The intestine plays a pivotal role in the nutrition and overall health of fishes. The present study sought to evaluate the effects of fasting and refeeding on body weight, intestine somatic index (ISI),
