Route of metabolization and detoxication of paralytic shellfish toxins in humans
Toxicon, 2010 Paralytic shellfish toxins (PST) are a collection of over 26 structurally related imidazoline guanidinium derivatives produced by marine dinoflagellates and freshwater cyanobacteria. Glucuronidation of drugs by UDP-glucuronosyltransferase (UGT) is the major phase II conjugation reaction in mammalian liver.

Chemistry – A European Journal, EarlyView.Levamisole is a common adulterant found in street‐distributed cocaine. Molecular baskets have been shown to form stable inclusion complexes with both substances. While levamisole inserts its benzene into the basket's cavity, cocaine utilizes its bicyclic ring for encapsulation.

Liquid Chromatographic-Fluorometric Analysis of Paralytic Shellfish Toxins
Agricultural and Biological Chemistry, 1984 Alkaline oxidation of paralytic shellfish toxins with ten-butyl hydroperoxide yielded highly fluorescent derivatives. Even gonyautoxins I and IV and neosaxitoxin, which were nonfluorescing by previously proposed hydrogen peroxide oxidations, were successfully converted to fluorescent compounds.

Developmental Dynamics, EarlyView.Abstract The sea anemone, Nematostella vectensis, has been used as a model organism in developmental biology studies for many years. This estuarine species has the notable capacity to regenerate its full body plan from small pieces throughout life. Nematostella have been described as having a great degree of cellular plasticity.

Decolorization of Ponceau Red 4R with TiO2/ZnO: Effect of calcination temperature and Fe addition
Environmental Progress &Sustainable Energy, EarlyView.Abstract The photocatalytic degradation of azo dyes using semiconductor oxides has emerged as a promising strategy for wastewater remediation. In this study, pure, mixed, and Fe‐doped oxide catalysts based on Zinc Oxide and Titanium Dioxide were synthesized and evaluated for the degradation of Ponceau 4R under ultraviolet irradiation.

Paralytic Toxins in the Dinoflagellate Gonyaulax excavata and in Shellfish
, 1978 Paralytic toxins were examined quantitatively in a culture of Gonyaulax excavata and in shellfish by the standard mouse bioassay and by an alkaline peroxide oxidation–fluorometric assay for saxitoxin (STX).
