Microcystin-LR Combined with Cadmium Exposures and the Risk of Chronic Kidney Disease: A Case–Control Study in Central China

, 2022
Increasing evidence indicates that exposure to microcystin-LR (MC-LR) can cause kidney damage. However, the association between MC-LR exposure and chronic kidney disease (CKD) risk in humans has not been studied.

High Levels of Structural Diversity Observed in Microcystins from Microcystis CAWBG11 and Characterization of Six New Microcystin Congeners

Marine Drugs, 2014
Microcystins (MCs) are cyclic peptides produced by cyanobacteria, which can be harmful to humans and animals when ingested. Differences in the coding of the non‑ribosomal peptide synthetase/polyketide synthase enzyme complex responsible for microcystin ...

Toxicity Differences Between Microplastics and Nanoplastics in Organs: From Molecular Mechanisms to Potential Therapeutic Strategies

Med Research, EarlyView.
This review systematically compares the size‐dependent toxicity of microplastics and nanoplastics in the intestine, liver, kidney, lung, and brain. Particle size determines bioavailability, barrier penetration, and injury mechanisms. Because of their small size and high surface reactivity, NPs readily cross the intestinal epithelium and blood–brain ...

Investigation of Microcystin Processing, Production and Export by Microcystis sp. [PDF]

, 2014
During this study, the effect of different processing methods on the microcystin quota (microcystins per cell) was investigated. Microcystins from two Microcystis strains and one Planktothrix strain were quantified using liquid chromatography-mass ...

Evidence of the cost of the production of microcystins by Microcystis aeruginosa under differing light and nitrate environmental conditions. [PDF]

PLoS ONE, 2012
The cyanobacterium Microcystis aeruginosa is known to proliferate in freshwater ecosystems and to produce microcystins. It is now well established that much of the variability of bloom toxicity is due to differences in the relative proportions of ...

Synergistic and Antagonistic Effects of Chemical Pollutants and Parasitic Fungi on Cyanobacterial Metabolism

Environmental Toxicology, EarlyView.
ABSTRACT Freshwater ecosystems are increasingly impacted by anthropogenic pollutants, including the widely used herbicide metolachlor (MET) and cigarette butt (CB) litter. Parasites represent an additional biotic stressor that can modulate pollutant effects on their hosts.

Microcystin-LR removal from Microcystis aeruginosa using in natura sugarcane bagasse and activated carbono

, 2016
Microcystin-LR is a type of toxin released by the Microcystis aeruginosa cyanobacteria found in water sources used for human consumption. It can cause illness and even death if not completely removed in conventional water treatment. The retention of this

Increased Prorenin Expression in the Kidneys May Be Involved in the Abnormal Renal Function Caused by Prolonged Environmental Exposure to Microcystin-LR

Toxics
Toxic algae in eutrophic lakes produce cyanotoxic microcystins. Prior research on the effect of microcystin-LR in the kidney utilized intraperitoneal injections, which did not reflect natural exposure.

Effects of Dietary Astaxanthin Supplementation on Energy Budget and Bioaccumulation in Procambarus clarkii (Girard, 1852) Crayfish under Microcystin-LR Stress

Toxins, 2018
This research aimed to study the effects of astaxanthin on energy budget and bioaccumulation of microcystin-leucine-arginine (microcystin-LR) in the crayfish Procambarus clarkii (Girard, 1852).

Strategies for enhancing sensitivity in lateral flow assays

VIEW, EarlyView.
Lateral flow assays (LFAs) are essential for cost‐effective, rapid point‐of‐care diagnostics. However, conventional colourimetric LFAs often lack the sensitivity required for low‐abundance biomarkers. This review evaluates six enhancement strategies: flow modulation, sample preconcentration, advanced reporters, chemical signal amplification, structural
