Using comparative extinction risk analysis to prioritize the IUCN Red List reassessments of amphibians. [PDF]

open access: yesConserv Biol
Abstract Assessing the extinction risk of species based on the International Union for Conservation of Nature (IUCN) Red List (RL) is key to guiding conservation policies and reducing biodiversity loss. This process is resource demanding, however, and requires continuous updating, which becomes increasingly difficult as new species are added to the RL.

Binding of Hg(I) and Hg(II) Ions to Amyloid-Beta (Aβ) Peptide Variants Affect their Structure and Aggregation. [PDF]

open access: yesChembiochem
Mercury (Hg) is a possible risk factor for Alzheimer's disease, where neuronal death is related to amyloid brain plaques containing aggregated amyloid‐β (Aβ) peptides. We show that equimolar Hg(I) or Hg(II) ions inhibit normal Aβ aggregation. Hg(II) binds Aβ(1–40) with an apparent binding affinity 28 ± 8 μM.

A Mg-Chelatase Subunit I Missense Mutant in Barley Exhibits a Cold-Sensitive Phenotype Under Field Conditions. [PDF]

open access: yesPhysiol Plant
ABSTRACT The pale‐green barley mutant xan‐h.chli‐1 has a HvCHLI subunit of Mg‐chelatase with an Arg‐to‐Lys substitution at position 298 and exhibits a unique cold‐sensitive phenotype. Under winter field conditions, xan‐h.chli‐1 plants fail to survive, whereas they thrive under spring or greenhouse conditions. Controlled experiments show a specific cold‐

Purple‐Light Promoted Thiol‐ene Reaction of Alkenes

open access: yesAdvanced Synthesis &Catalysis, Volume 365, Issue 24, Page 4623-4633, December 19, 2023., 2023
Abstract Here we present a catalyst‐free protocol for the purple light‐mediated anti‐Markovnikov functionalization of alkenes with thiols. Crucial to the generation of the thiyl radical was the formation of a key photo‐active complex. More than 30 thioether products were obtained, demonstrating tolerance towards different functional groups and ...
