Prenatal and Early Childhood Exposure to Antibiotics or Gastric Acid Inhibitors and Increased Risk of Epilepsy: A Nationwide Population‐Based Study

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Over 10 million children in the world have epilepsy, with an unknown cause in half of the cases. The gut microbiome has been associated with various neurological disorders, and certain drugs greatly disturb the microbiome. Our aim was to study the association of prenatal and childhood exposure (before the age of two) to antibiotics, proton pump ...

An Iron‐Catalyzed Sustainable Functional Group Transfer Strategy for In‐Water Transformation of Organic Sulfides to Sulfoxides by a Hydroxylamine‐Derived Oxidant

open access: yesChemSusChem, EarlyView.
An iron‐catalyzed ecofriendly reaction protocol is demonstrated to chemoselectively convert readily available organic sulfides to valuable sulfoxides, under mild reaction conditions in water. The functional group tolerance, scalability, reaction compatibility, and potential application make the protocol highly attractive in terms of green and ...
