Removal of microcystin-LR from aqueous solutions using % burn-off activated carbon of waste wood material [PDF]
, 2014 The activated carbon (AC), prepared at different burn-off rates, showed a high uptake of methylene blue. At 93% burn-off, methylene blue uptake was 620 mg/g.

Proteasome as a Molecular Target of Microcystin-LR [PDF]
Toxins, 2015 Proteasome degrades proteins in eukaryotic cells. As such, the proteasome is crucial in cell cycle and function. This study proved that microcystin-LR (MC-LR), which is a toxic by-product of algal bloom, can target cellular proteasome and selectively inhibit proteasome trypsin-like (TL) activity. MC-LR at 1 nM can inhibit up to 54% of the purified 20S

Increasing Microcystis cell density enhances microcystin synthesis: a mesocosm study [PDF]
, 2012 An experimental protocol using mesocosms was established to study the effect of Microcystis sp. cell abundance on microcystin production. The mesocosms (55 L) were set up in a shallow eutrophic lake and received either no (control), low (to simulate a ...

Immunohistochemical Localization of Microcystin-LR in the Liver of Mice: A Study on the Pathogenesis of Microcystin-LR-Induced Hepatotoxicity [PDF]
Toxicologic Pathology, 1998 The relationship between the intralobular sites of hepatotoxic injury and the distribution of microcystin-LR (MCLR), an inhibitor of protein phosphatases 1 (PP1) and 2A (PP2A), was examined using an immunohistochemical method with a monoclonal antibody specific to MCLR on the livers of mice receiving a single ip injection of the MCLR.

An overview of the toxic effect of potential human carcinogen Microcystin-LR on testis
Toxicology Reports, 2015 The worldwide occurrence of cyanobacterial blooms due to water eutrophication evokes extreme concerns. These blooms produce cyanotoxins which are hazardous to living organisms.

Bioavailability of microcystin-LR in two different soil types to the legume Alfalfa Medicago sativa L. [PDF]
, 2021 The adverse effects of exposure to microcystins in terrestrial crops have been well documented. However, the retention and bioavailability of microcystin-LR, one of the most prevalent cyanotoxins, from soil to plants, is poorly understood. In the present

Transgenerational effects of microcystin-LR onDaphnia magna [PDF]
Journal of Experimental Biology, 2012 SUMMARYAnthropogenic and climate factors increase the frequency of problematic cyanobacterial blooms in freshwater. Among other toxins, some cyanobacteria produce microcystins (MCs), which inhibit phosphatases type 1 and type 2A and provokes oxidative stress.

Variations in the Microcystin Content of Different Fish Species Collected from a Eutrophic Lake
Toxins, 2013 Microcystins produced from cyanobacteria can accumulate in fish tissues. Liquid chromatography coupled with tandem quadrupole mass spectrometry (LC-MS/MS) is an attractive alternative to immunoassays for the determination of low concentrations of ...
