Histopathological changes in liver and gill of Acipenser persicus fry in short term exposure to Nodularia spumigena

Caspian Journal of Environmental Sciences, 2014
Persian sturgeon, Acipenser persicus is a native, commercially important and highly steemed fish species in the Caspian Sea. In this study, effects of Nodularin (NODLN), a cyclic pentapeptide hepatotoxin, on liver and gill tissues of A.

Evaluation of Carbonized Corncobs for Removal of Microcystins and Nodularin-R from Water

Separations
Microcystins (MCs) and nodularins (NODs) are cyanotoxins that can be found in water bodies during cyanobacterial harmful algal blooms (cyanoHABs). Consumption of water contaminated with cyanotoxins leads to health risks for humans and animals.

Toxic Nodularia spumigena blooms in the coastal waters of the Gulf of Gdańsk: a ten-year survey

Oceanologia, 2006
In the Baltic Sea, summer blooms of the filamentous, nitrogen-fixingcyanobacterium Nodularia spumigena are favoured by high P concentrationsat low N:P ratios and a salinity range of 5-13 PSU. The bloomsare initiated by calm and sunny weather, an elevated

Synthesis of cyclic peptides modelled on the microcystin and nodularin rings

, 1996
Several precursor cyclic peptides modelled on the ring systems of microcystin-LR and nodularin were synthesized. Synthesis was best achieved using solid-phase cyclization with solution-phase methods being successful in only one instance.

Nodularin and cylindrospermopsin: a review of their effects on fish

, 2015
Nodularin (NOD) and cylindrospermopsin (CYN) are hepatotoxic cyanotoxins that are present in numerous ecosystems where bloom episodes occur. In this review, the different effects of both of these cyanotoxins on the different ontogenic stages of various fish species were summarised to clarify the state-of-the-art scientific knowledge on this topic.

Comparative effects of nodularin and microcystin-LR in zebrafish: 2. Uptake and molecular effects in eleuthero-embryos and adult liver with focus on endoplasmic reticulum stress

, 2016
Microcystin (MC) and nodularin are structurally similar cyanobacterial toxins that inhibit protein phosphatases. Additional modes of action are poorly known, in particular for nodularin.

Production of cyanobacterial toxins from two Nostoc species (Nostocales) and evaluation of their cytotoxicity in vitro [PDF]

Journal of BioScience and Biotechnology, 2012
Cyanobacteria are among the oldest autotrophic organisms with cosmopolitan distribution and known as producers of secondary metabolites with toxic properties named "cyanotoxins".

Rapid clean-up and effective sample preparation procedure for unambiguous determination of the cyclic peptides microcystin and nodularin

, 1999
A new sample preparation strategy has been established to improve the identification and determination of nodularin and microcystins. The sample preparation consisted of enrichment of the analytes by solid phase extraction with C18 cartridges followed by

Determination of six microcystins and nodularin in surface and drinking waters by on-line solid phase extraction–ultra high pressure liquid chromatography tandem mass spectrometry

, 2012
Microcystins and nodularin are cyclic peptides hepatotoxins produced by cyanobacterial genera (blue-green algae). Toxic cyanobacterial blooms are a worldwide problem, as reported in several countries, like China, Australia, or the United States ...
