exploring the mass gap:Black holes in green pea galaxies

Science China(Physics,Mechanics & Astronomy) 2024年第10期67卷 170-171页

作者： james e.Rhoads School of earth and Space exploration Arizona State UniversityTempeAZ 85287USA

We know about black holes primarily on two mass scales(e.g.,see Figure 22 of ref.[1]).Supermassive black holes inhabit the centers of galaxies,where they sometimes power active galactic nuclei(AGN).Their populations can be probed through AGN surveys,tidal disruption event surveys,and(in the closest galaxies)stellar and gas dynamics in the innermost regions where the black hole dominates the gravitational potential.

Toxicity of a seafood toxin， domoic acid， in the retina via modulation of the NRF2 and NF-κB pathways

引用

Food Science and Human Wellness 2024年

作者： Gabriel Mbuta Tchivelekete Yanqun Cao Mohammad Almarhoun Xinzhi Zhou Agostinho Francisco Cachapa Sebasti?o Tumitangua james Reilly Patricia e.Martin Xinhua Shu Department of Biological and Biomedical Sciences， Glasgow Caledonian University Department of Marine Biology， Faculty of Natural Science， University of Namibe Puai Medical School， Shaoyang University Department of Vision Science， Glasgow Caledonian University

Domoic acid (DA)， a biotoxin， is produced by several species of marine dinoflagellate and diatom during harmful algal bloom events. DA is a neurotoxin， in humans and non-human primates， oral exposure to DA results in gastrointestinal effects， while DA at higher doses leads to neurological symptoms， seizures and memory deficiency. exposure of humans to DA occurs mainly through consumption of contaminated seafoods containing an accumulation of the toxin. Previously， it was unclear if DA can have toxic effects on the retina. We assessed the toxicity of DA in human retinal cells (ARPe-19) and in zebrafish embryos. DA significantly lowered ARPe-19 cell viability dose-dependently， and decreased anti-oxidative capacity， increased inflammation， and promoted cell death， possibly through modulating the NRF2 and NF-κB signalling pathways. Zebrafish embryos exposed to DA for four days from one day post fertilization (dpf) had an increase in mortality and a decrease in both hatching and heartbeat rate and exhibited morphological abnormalities. DA treatment also significantly downregulated expression of antioxidant genes and upregulated expression of inflammation mediators， as well as causing photoreceptor death in zebrafish embryos. The results demonstrate that consuming seafood containing DA will have potential toxic effects in human retinas.
