Contact Dermatitis, EarlyView.A case series of eight patients with allergic otitis externa from contact allergy to hearing aid ear moulds is presented. All were patch test positive to tetrahydrofurfuryl methacrylate and three to isobornyl acrylate. It is postulated that these are likely relevant allergens present in such devices. ABSTRACT Background Allergic contact dermatitis from

, 2021 We previously found that the immune response to haptens is positively correlated with molecular hydrophobicity. The antibodies used in immunoassays for capsaicinoids (CPCs) in waste oil suffer from low affinity and loose recognition to structural ...

Contact Dermatitis, EarlyView.We evaluated the reproducibility of positive patch test reactions to identical haptens tested simultaneously in different series and analysed doubtful reactions using paired co‐reactivity patterns. Reproducibility was highly hapten‐dependent. Hydroxyethyl methacrylate and mercaptobenzothiazole showed substantial to almost perfect agreement, but ...

Changing Functionality of Surfaces by Directed Self-Assembly Using Oligonucleotides—The Oligo-Tag
BioTechniques, 1999 A method is presented to modify surfaces for biotechnological applications. Oligonucleotides have been coupled covalently to a pre-activated surface. Complementary oligonucleotides hybridize to the surface, which are conjugated with functionalities.

Contact Dermatitis, EarlyView.In retrospective studies the prevalence of tin sensitization and its clinical relevance was evaluated in two groups: consecutive patients and patients suspected of metal allergies. The prevalence was higher than previously reported and relevance could be established for ~30%.

Alergologia PolskaExperts agree that patch test is nowadays the only validated method for the detection of contact allergy to haptens. Facing more than 5200 known haptens, starting with sensitizers most frequent in a given population seems most reasonable. Baseline series

Autoimmunity and Periodontitis
Journal of Periodontal Research, EarlyView.In a microbe‐driven inflammatory environment, peptidyl‐arginine deiminase (PAD) enzymes from neutrophils and Porphyromonas gingivalis citrullinate both microbial and self‐antigens. B cell presentation of citrullinated or self‐mimicking epitopes activates T cells that assist B cells in antibody isotype switching, affinity maturation, epitope spreading ...

NLRP3 Inflammasome and Allergic Contact Dermatitis: A Connection to Demystify
Pharmaceutics, 2020 Allergic contact dermatitis is a common occupational disease that manifests as a cell-mediated hypersensitivity reaction following skin exposure to small reactive chemicals termed haptens.

, 2000 Two 2-aminophosphonate haptens derived from methyl α-d-glucopyranoside were synthesized to mimic the transition-state of a transesterification reaction between methyl α-d-glucopyranoside and 4-nitrophenylester of tert-BOC-β-alanine.
