Metal cations recognition by bowl-shaped -pyrrolic polycyclic aromatic hydrocarbons.
Chem Commun (Camb)
September 2024
Bowl-shaped, nitrogen-doped polycyclic aromatic hydrocarbons were examined for the first time as molecular receptors for the recognition of metal cations. Potentiometric and spectrofluorimetric assays, supported with density functional theory computations, revealed that the title compounds recognise metal cations with a special focus on caesium (Cs) cations.

- Some babies have a higher risk of getting peanut allergies if they have severe eczema, another food allergy, or a family member with peanut allergies.
- Researchers tested 321 babies who were between 4 to 11 months old to see if they might be allergic to peanuts before they had any.
- They found that babies with bad eczema had a good chance of having a peanut allergy, while those without eczema and just a family history were much less likely to have one.
Background: Screening of high-risk infants for peanut allergy (PA) before introduction is now recommended in the United States, but the optimal approach is not clear.
Objective: We sought to compare the diagnostic test characteristics of peanut skin prick test (SPT), peanut-specific IgE (sIgE), and sIgE to peanut components in a screening population of infants before known peanut exposure.
Methods: Infants aged 4 to 11 months with (1) no history of peanut ingestion, testing, or reaction and (2) (a) moderate-severe eczema, (b) history of food allergy, and/or (c) first-degree relative with a history of PA received peanut SPT, peanut-sIgE and component-IgE testing, and, depending on SPT wheal size, oral food challenge or observed feeding.
