Background Biliary atresia(BA)is one of the main causes of neonatal end-stage liver *** timely diagnosis and treatment,most children with BA will develop irreversible liver fibrosis within the first two *** current theorized causes of BA include viral infection,immune disorders,and genetic defects,the comprehensive etiology is still largely ***,biliatresone attracted much interest for its ability to induce BA in both zebrafish and mice,so we summarized the latest progress of biliatresone research in BA and tried to answer the question of whether it could provide further clues to the etiology of human *** sources We conducted a PubMed search for any published articles related to the topic using search terms including“biliary atresia”,“biliatresone”,“GSH”,and“HSP90”.Relevant data were extracted from the original text or supplementary materials of the corresponding *** Biliatresone had shown its unique toxicity in multiple species such as zebrafish and mice,and pathogenic factors involved included glutathione(GSH),heat shock protein 90(HSP90)and the related *** combination with epidemiological evidence and recent studies on the intestinal flora in biliary atresia,a new pathogenic hypothesis that the occurrence of biliary atresia is partly due to biliatresone or its structure-like compounds depositing in human body via vegetables or/and the altered intestinal flora structure can be tentatively *** Based on the existing evidence,we emphasized that GSH and HSP90 are involved in the development of BA,and the maternal diet,especially higher vegetable intake of Asian women of childbearing age,accompanied by the altered intestinal flora structure,may contribute to the occurrence of biliary atresia and the higher incidence in the Asia ***,the evidence from large sample epidemiological research is necessary.

Input associativity underlies fear memory renewal

Synaptic associativity, a feature of Hebbian plasticity wherein coactivation of two inputs onto the same neuron produces synergistic actions on postsynaptic activity, is a primary cellular correlate of associative learning. However, whether and how synaptic associativity are implemented into context-dependent relapse of extinguished memory(i.e. fear renewal) is unknown. Here, using an auditory fear conditioning paradigm in mice, we show that fear renewal is determined by the associativity between convergent inputs from the auditory cortex(ACx) and ventral hippocampus(v HPC) onto the lateral amygdala(LA) that reactivate ensembles engaged during learning. Fear renewal enhances synaptic strengths of both ACx to LA and the previously unknown v HPC to LA monosynaptic inputs. While inactivating either of the afferents abolishes fear renewal, optogenetic activation of their input associativity in the LA recapitulates fear renewal. Thus, input associativity underlies fear memory renewal.

Cyano migration-mediated radical-polar crossover cyclopropanation

作者： Ziqiang Wang Yasu Chen jie Li Chen zhu Key Laboratory of Organic Synthesis of jiangsu Province College of Chemistry Chemical Engineering and Materials ScienceSoochow University Frontiers Science Center for Transformative Molecules Zhangjiang Institute for Advanced Study and Shanghai Key Laboratory for Molecular Engineering of Chiral Drugs Shanghai Jiao Tong University

We report a novel cyano migration-mediated radical-polar crossover process, whereby both the sulfonylcyanation of aliphatic alkenes and the formation of cyclopropanes are concurrently achieved. This transformation yields a diverse array of multisubstituted cyclopropanes under mild photocatalytic conditions. Mechanistic studies elucidate that the reaction proceeds via intramolecular nucleophilic substitution, leading to the formation of the cyclopropane derivatives.
