TL;DR: Results reveal unanticipated risks of 6PPD antioxidants to an aquatic species and imply toxicological relevance for dissipated tire rubber residues, and identify a highly toxic quinone transformation product of N-(1,3-dimethylbutyl)-N′-phenyl-p- Phenylenediamine (6PPD), a globally ubiquitous tire rubber antioxidant.

TL;DR: In this paper, a 24-week laboratory incubation study was conducted to investigate short-term soil microbial responses to biochar addition, and the results collectively suggest that biochar amendment increases the activity of specific microorganisms in soil, leading to increased CO2 fluxes and degradation of labile soil OM constituents.

TL;DR: It is shown by pulsed field gradient NMR spectroscopy that the monomeric form of the toxic, amyloidogenic human variant of IAPP (hIAPP) adopts a temperature dependent compact folded conformation that is absent in both the nontoxic and nonamyloidgenic rat variant ofIAPP and absent in hIAPP at low temperatures, suggesting this compact form of monomersic IAPP may be linked to its later aggregation and cytotoxicity.

TL;DR: An introduction to the properties of lipid bicelle phases with an emphasis on NMR experimental measurements is given and some of the most exciting recent applications of bicelles in the structural and dynamic studies of membrane proteins are discussed.

TL;DR: The structure of the cytb5-cytP450 complex allows us to propose an interprotein electron transfer pathway involving the highly conserved Arg-125 on cytB5 serving as a salt bridge between the heme propionates of cytP450 and cytb 5.
