Background: The values of the skin prick test (SPT) and allergen-specific IgE (sIgE) measurement in predicting dog and cat allergies remain unclear. We aimed to evaluate the usefulness of SPT and sIgE measurement in predicting self-reported allergic symptoms during exposure to dogs and cats in Korean adults.

Methods: A total of 552 participants in a pet exhibition in Korea completed questionnaires regarding exposure to dog or cat and the development of allergic symptoms during exposure.

Mutations in the rpoB gene of Mycobacterium tuberculosis can result in resistance to rifampin. Among various mutations in the rpoB gene, some known as disputed rpoB mutations can cause low-level rifampin resistance. It has been suggested that a high-dose rifampin (20 mg/kg)-based regimen might be effective in treating tuberculosis (TB) caused by M.

The Brønsted acid catalyzed Meyer-Schuster reaction of hemiaminals was studied for the stereoselective synthesis of β-enaminones. Hemiaminals were formed from propargyl aldehydes (or the oxidation of propargyl alcohols) and amines in the presence of Brønsted acids. A critical step to control the stereochemistry of the products is the protonation of the corresponding allenol intermediate, which is dictated by the Brønsted acid used, the steric effect of the amine, and the electronic effect of the propargyl aldehyde.

A variety of vinylic alkoxyamines derived from propargyl alcohols and 2,2,6,6-tetramethylpiperidine N-oxyl (TEMPO) were synthesized in good yields under copper-catalyzed aerobic conditions. A reaction mechanism was proposed, involving the isomerization of propargyl radicals to allenic radicals, and related mechanistic studies were performed. The kinetic isotope effect on the propargyl C-H bond cleavage (α-deprotonation) reaction was observed (kH/kD = 3.
