Molecular imprinting-based indirect fluorescence detection strategy implemented on paper chip for non-fluorescent microcystin

Nature Communications, 2023
Fluorescence analysis is a fast and sensitive method, and has great potential application in trace detection of environmental toxins. However, many important environmental toxins are non-fluorescent substances, and it is still a challenge to construct a ...

Lost in aggregation? On the importance of local food price data for food poverty estimates

American Journal of Agricultural Economics, EarlyView.
Abstract This paper explores within‐country variations in food price dynamics and food poverty estimates by employing local market price data and national consumer price index (CPI) data. Our results show that national CPI data may be useful for approximating national trends but they fail to detect and identify spatial variations in local trends, which

Development of an Ocean Acidification Simulation System and Its Preliminary Application to Trace-Metal Size Fractionation in Seawater

Journal of Marine Science and Engineering
A closed-loop CO2-aeration system, with integrated pH feedback, multiparameter sensing, water circulation, RS485 communication, stainless-steel gas-path valves, and fluorinated vessel interiors, was developed for controlled trace-metal size-fractionation

Diagnosing the system: Mental health, necropolitical uncare, and the abolition of migration detention

American Journal of Community Psychology, EarlyView.
Abstract This article examines the psychological effects of migration detention in the European Union's Closed Controlled Access Center (CCAC) on Samos through an ecological lens. It explores a double normalization of suffering: the brutalization of necropolitical migration governance and the simultaneous understanding of resulting distress as an ...

Chemical Cues Released by Predators’ Consumption of Heterospecific Prey Alter the Embryogenesis of Zebrafish

Fishes
Environmentally cued hatching is prevalent, diverse, and crucial to many animals’ survival. Fish embryos use a variety of chemical cues to initiate hatching to avoid potential predators, yet the function of chemical cues released from the predatory ...

Rate and Shape of Functional Decline in Amyotrophic Lateral Sclerosis Identify Clinically Distinct Amyotrophic Lateral Sclerosis Phenotypes

Annals of Neurology, EarlyView.
Objective The ALS Functional Rating Scale–Revised decline rate compresses trajectory shape into a single number, potentially missing distinct phenotypes. We tested whether shape identifies phenotypes that rate does not distinguish, and whether post‐hoc analysis recovers a hidden ultrarapid subgroup. Methods From the Piemonte and Valle d'Aosta register (

Low pH in simulated acid rain promotes the toxicity of copper on the physiological performance in Sargassum horneri

Photosynthetica, 2020
In order to investigate the interactive effects of simulated acid rain and copper (Cu) on macroalgae, Sargassum horneri was cultured under pH of 8.2, 5.6, 4.5 and Cu concentrations of 0, 25, 100 μg L-1.
