A carbamoylase-based bioassay for the detection of paralytic shellfish poisoning toxins - Raposo M, Botelho MJ, Costa ST, Gomes MTSR, Rudnitskaya A.

Out of control proliferation of toxic phytoplankton, called harmful algal blooms (HABs), have a significant economic impact on bivalve aquaculture and harvesting in coastal waters. Some phytotoxins, such as paralytic shellfish toxins (PSTs), are of concern...

SalesAbstractHistamine (HIS) is a major public health problem due to its toxic properties. High levels can cause a chronic toxicity as poisoning and can be used as a signal of food hygiene. Thus, a new electrochemical sensor for HIS detection in fish is presented herein, prepared by tailoring a molecularly imprinted polymer (MIP) sensing material on a gold screen-printed electrode (Au-SPEs), in which the polymeric film was generated in-situ. This...

PetterssonAbstractTwo different SCR catalysts, V2O5-WO3/TiO2 and Cu-SSZ-13, were exposed to biodiesel exhausts generated by a diesel burner. The effect of phosphorus and sulfur on the SCR performance of these catalysts was investigated by doping the fuel with P-, S-, or P + S-containing compounds. Elemental analyses showed that both catalysts captured phosphorus while only Cu-SSZ-13 captured sulfur....

ConclusionPresence of a proximal bystander during an overdose event is associated with dispatch codes indicative of an overdose and shorter times to naloxone administration compared with those with distal bystanders. These findings offer opportunities for public education and engagement of overdose harm reduction strategies. PMID: 32073921 [PubMed - as supplied by publisher]

These nitrile-containing compounds do not present toxic effects in intact form while they produce toxic cyanide following enzymatic digestion. Therefore, over-consuming of these compounds can lead to cyanide poisoning. On the other hand, s...

This study demonstrates that the LUCS test method could be relevant for assessing human acute oral toxicity with a simplified protocol adapted to commercially available fluorescence readers. We suggest that this new alternative method can be used for acute systemic toxicity testing in combination with other tests under European REACH and other regulations, wherever pertinent alternative methods are still lacking.Graphical abstract

Abstract In 2011, Florida established a Prescription Drug Monitoring Program and adopted new regulations for independent pain-management clinics. This paper examines the association of those reforms with drug overdose deaths and other injury fatalities. Florida's post-reform monthly mortality rates - for drug-involved deaths, motor vehicle crashes, and suicides by means other than poisoning - were compared to a counterfactual estimate of what those rates would have been absent reform. The counterfactual was estimated using a Bayesian structural time-series model based on mortality trends in similar states. By Dece...

(US Department of Agriculture - Agricultural Research Service) A simple, portable test that can detect the deadliest of the mushroom poisons in minutes has been developed by Agricultural Research Service (ARS) scientists. Eating toxic mushrooms causes more than 100 deaths a year, globally, and leaves thousands of people in need of urgent medical assistance. Amanitin is the class of mushroom toxins that cause the most serious issues.
