Allergic Sensitization to Inhalant Allergens in the Upper Respiratory Tract—the B Cell Side
Allergy, EarlyView.ABSTRACT Allergic diseases are on the rise worldwide, driven by respiratory epithelial barrier dysfunction that promotes sensitization to inhalant allergens such as pollen, dust mites, pet dander, and fungal spores. These antigens trigger IgE‐mediated immune responses that lead to diseases such as allergic rhinitis (AR) and asthma.

The plasticisation model of dye diffusion: Part 5
Coloration Technology, EarlyView.Abstract The findings presented in the previous part of the paper (Part 4) of the re‐evaluation of previously published data reported for the temperature‐dependent diffusion of an organic acid within nylon 6 film, desorption of three acid dyes from dyed nylon 66 fabric, diffusion of an acid dye within nylon 6 monofilaments and adsorption of a sulphur ...

The plasticisation model of dye diffusion: Part 7
Coloration Technology, EarlyView.Abstract Re‐evaluation using the Williams‐Landel‐Ferry equation, of exhaustion/fixation/adsorption data previously reported for four classes of anionic dye onto three different types of wool substrate, revealed that thermally activated dyeing/desorption behaviour is governed by the thermally regulated structural relaxation times of the respective water‐

2,3,5,6-Tetrafluoro-[N-(3-aminopropyl)-ε-caprolactam]-4-pyridine
MolbankThe title compound was synthesized at a near-quantitative yield using the nucleophilic aromatic substitution of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) with perfluoropyridine (PFP). The purity and structure were determined by NMR (1H, 13C, 19F), GC-EIMS,
