^1H{^(19)F} NOE NMR Structural Signatures of the Insulin R_6 Hexamer: Evidence of a Capped HisB10 Site in Aryl- and Arylacryloyl-carboxylate Complexes
New and improved insulin: ^1H{^(19)F} NOE NMR difference spectra for CF_3-substituted aromatic carboxylates bound at the HisB10 sites of the R_6 human insulin (HI) hexamer show strong NOEs between the CF_3 groups and the LeuB6, AsnB3, and PheB1 sidechains. The NOEs and structural modeling establish that these carboxylates form closed complexes with the HisB10 site capped by the PheB1 rings
Behavioral strategy in the wild
Purpose A decade after Powell et al.’s (2011) seminal article on behavioral strategy, which called for models to solve real-world problems, the authors revisit the field to ask whether behavioral strategy is coming of age. The purpose of this paper is to explain how behavioral strategy can and has been used in real-world settings. Design/methodology/approach This study presents a conceptual review with case study examples of the impact of behavioral strategy on real-world problems. Findings This study illustrates several examples where behavioral strategy debiasing has been effective. Although no causal claims can be made, with the stark contrast between the negative impact of biased strategies and the positive results emerging from debiasing techniques, this study argues that there is evidence of the benefits of a behavioral strategy mindset, and that this should be the mindset of a responsible strategic leader. Practical implications This study presents a demonstration of analytical, debate and organizational debiasing techniques and how they are being used in real-world settings, specifically military intelligence, Mergers and acquisitions deal-making, resource allocation and capital projects. Social implications Behavioral strategy has broad application in private and public sectors. It has proven practical value in various settings, for example, the application of reference class forecasting in large infrastructure projects.

Controlling the growth of palladium aerogels with high-performance toward bioelectrocatalytic oxidation of glucose
We report the controllable synthesis of Pd aerogels with high surface area and porosity by destabilizing colloidal solutions of Pd nanoparticles with variable concentrations of calcium ions. Enzyme electrodes based on Pd aerogels co-immobilized with glucose oxidase show high activity toward glucose oxidation and are promising materials for applications in bioelectronics
Direct Conjugation of Emerging Contaminants in <i>Arabidopsis</i>: Indication for an Overlooked Risk in Plants?
Agricultural use of treated wastewater,
biosolids, and animal wastes
introduces a multitude of contaminants of emerging concerns (CECs)
into the soil-plant system. The potential for food crops to accumulate
CECs depends largely on their metabolism in plants, which at present
is poorly understood. Here, we evaluated the metabolism of naproxen
and ibuprofen, two of the most-used human drugs from the Profen family,
in <i>Arabidopsis thaliana</i> cells and the <i>Arabidopsis</i> plant. The complementary use of high-resolution mass spectrometry
and <sup>14</sup>C labeling allowed the characterization of both free
and conjugated metabolites, as well as nonextractable residues. Naproxen
and ibuprofen, in their parent form, were conjugated quickly and directly
with glutamic acid and glutamine, and further with peptides, in <i>A. thaliana</i> cells. For example, after 120 h, the metabolites
of naproxen accounted for >90% of the extractable chemical mass,
while
the intact parent itself was negligible. The structures of glutamate
and glutamine conjugates were confirmed using synthesized standards
and further verified in whole plants. Amino acid conjugates may easily
deconjugate, releasing the parent molecule. This finding highlights
the possibility that the bioactivity of such CECs may be effectively
preserved through direct conjugation, a previously overlooked risk.
Many other CECs are also carboxylic acids, such as the profens. Therefore,
direct conjugation may be a common route for plant metabolism of these
CECs, making it imperative to consider conjugates when assessing their
risks
