Manganese accumulation in red blood cells as a biomarker of manganese exposure and neurotoxicity
Neurotoxicology. 2024 Mar 10;102:1-11. doi: 10.1016/j.neuro.2024.03.003. Online ahead of print.ABSTRACTAlthough overexposure to manganese (Mn) is known to cause neurotoxic damage, effective exposure markers for assessing Mn loading in Mn-exposed workers are lacking. Here, we construct a Mn-exposed rat model to perform correlation analysis between Mn-induced neurological damage and Mn levels in various biological samples. We combine this analysis with epidemiological investigation to assess whether Mn concentrations in red blood cells (MnRBCs) and urine (MnU) can be used as valid exposure markers. The results show that Mn e...

Heavy Metals in Common Fishes Consumed in Dhaka, a Megacity of Asia: A Probabilistic Carcinogenic and Non-Carcinogenic Health Hazard
In this study, six commonly consumed fish species namely Hilsha (Tenualosa ilisha), Kachki (Corica soborna), Punti (Puntitus ticto), Taki (Channa punctatus), Meni (Nandus nandus), and Tengra (Mystus tengara) were analyzed for arsenic (As), cadmium (Cd), lead (Pb), zinc (Zn), copper (Cu), chromium (Cr), manganese (Mn), and nickel (Ni), by inductively coupled plasma mass spectrometry. The fish samples were collected from wholesale markets in Dhaka city, the main business hub of Bangladesh where the fishes converged from countrywide and are redistributed to the whole city. The metal concentration varied among the studied fish...

Cascade reaction triggered colorimetric array for identification of organophosphorus pesticides congeners
Biosens Bioelectron. 2024 Feb 24;253:116143. doi: 10.1016/j.bios.2024.116143. Online ahead of print.ABSTRACTA modern agriculture uses alternative pest control methods to boost productivity, leading to an accumulation of organophosphorus (OPPs) congeners. This necessitates an intuitive and quick way to identify OPPs congeners. A colorimetric sensor for detecting OPPs congeners using a double-enzyme cascade reaction has been successfully designed and constructed in this study. The OPPs regulate the color changes induced by manganese dioxide nanoflowers (MnO2 NFs) and specific alkaline phosphatases (ALP) during the etching of...
