Association Between the Dutch Mediterranean-Dietary Approaches to Stop Hypertension Intervention for Neurodegenerative Delay (MIND-NL) Diet Adherence and Systemic Tryptophan Metabolites in Older Adults at Risk of Cognitive Decline: An Exploratory Study. [PDF]

Mol Nutr Food Res
Following the MIND diet may support brain health in older adults at risk of cognitive decline by influencing tryptophan (TRP) metabolism. Plasma samples and dietary intake data from the HELI intervention trial were used. Bivariate latent change score modeling analysis showed that greater adherence to the MIND diet was linked to higher tryptophan levels,

Non-conventional trans-platinum complexes functionalized with RDG peptides: chemical and cytototoxicity studies [PDF]

, 2017
In order to target platinum complexes to cancer cells, trans-Pt(II) or trans-Pt(IV) complexes were bioconjugated to the cyclic peptide cRGDfK (cRGD), with affinity for αvβ3 integrin receptors, through their 4-picolinic acid spectator ligands.

Sensing a Bacillis anthracis biomarker with well-known OLED emitter EuTta3Phen [PDF]

, 2016
Dipicolinic acid (DPA) is a distinctive biomarker for bacterial spores. Here, we present the successful demonstration of dramatic Switch-OFF sensing of DPA using an easily synthesised Eu(III) phosphor applied primarily in light-emitting devices.

Synthesis of highly functionalized 2,2'-bipyridines by cyclocondensation of β-ketoenamides – scope and limitations [PDF]

, 2016
The scope of a flexible route to unsymmetrically functionalized bipyridines is described. Starting from 1,3-diketones 1a–e, the corresponding β-ketoenamines 2a–e were converted into different β-ketoenamides 3a–g by N-acylation with 2-pyridinecarboxylic ...
