“…Based on the genome annotation, potential biocontrol genes were predicted to encode secreted hydrolases or to be part of secondary metabolite clusters (e.g., NRPS-like, NRPS, T1PKS, terpene, and β-lactone clusters). Transcriptome and secretome analyses defined a subset of 79 A. pullulans genes (among the 10,925 annotated genes) that were transcriptionally upregulated or exclusively detected at the protein level during the competition with F. oxysporum. …”

“…The Kc, stability constant of the two phase system of AND with 2-HyP-β-CYD computed to be 38.60 x 10(−3)M. (1)H NMR spectrum of AND indicated the presence of triplet at 6.63-ppm which was up-fielded in AND-2-HyP-β-CYD complex at 6.60-ppm (doublet) confirmed the insertion of AND in cavity of 2-HyP-β-CYD through lactone ring. AND-2-HyP-β-CYD complex exhibited the IC(50) of 0.1-μg.mL(−1) (E gene) and 0.29-μg.mL(−1) (N gene) against SARS-CoV-2 infected Vero6 cells. …”

“…The “Neighbourhoods in Solidarity” (NS) are a series of community-based interventions that aim to increase social connectedness and reduce loneliness in older adults (55+) in the canton of Vaud, Switzerland. This longitudinal embedded mixed-methods study aimed to understand whether older adults (distinguishing between locals, newcomers, and expats) were aware of and participated in the NS, to assess whether participation was associated with changes in loneliness, and to identify relevant processes that could explain a reduction in loneliness. …”

“…The starting synthetic step utilized a privileged asymmetric Mukaiyama aldol addition using Ti(OiPr)(4)/(S)-BINOL or Ti(OiPr)(4)/(R)-BINOL catalysis to afford the corresponding (R)- and (S)-δ-hydroxy-β-ketoesters, respectively, with highly enantiomeric excess (>98%). Conventional lactone formation and successive EDCI-mediated C-acylation produced the desired products, (R)- and (S)-plymuthipyranones B and three (R)- and (S)- synthetic analogues, with an overall yield of 42–56% with a highly enantiomeric excess (95–99%). …”
