Analysis of benzoyl-peroxide and formaldehyde as dental allergens by FT-SPR method
In parallel with the appearance of new dental materials the number of induced allergic diseases increases. Based on this fact more sensitive detection of allergens is major importance. The Fourier-Transform Surface Plasmon Resonance (FT-SPR) is a sensitive, broadly applicable real-time method for analysing thin layers of materials on gold surfaces. FT-SPR measurement is performed at a fixed ang...
متن کاملEffects of formaldehyde, acetaldehyde, benzoyl peroxide, and hydrogen peroxide on cultured normal human bronchial epithelial cells.
The effects of several aldehydes and peroxides on growth and differentiation of normal human bronchial epithelial cells were studied. Cells were exposed to formaldehyde, acetaldehyde, benzoyl peroxide (BPO), or hydrogen peroxide (HPO). The effect of each agent on the following parameters was measured: (a) clonal growth rate; (b) squamous differentiation; (c) DNA damage; (d) ornithine decarboxyl...
متن کاملTretinoin and Benzoyl Peroxide
A simple, sensitive, spectrophotometric method in UV region has been developed for the simultaneous estimation of benzoyl peroxide and tretinoin in bulk and semi solid dosage form (cream). Standard solution of benzoyl peroxide shows maximum absorbance at 234.8 nm and tretinoin shows maximum absorbance at 348.6 nm. Beer’s Lamberts law is obeyed in concentration range 1-9 μg/ml for tretinoin with...
متن کاملA new silver nanorod SPR probe for detection of trace benzoyl peroxide
The stable silver nanorod (AgNR) sol in red was prepared by the two-step procedure of NaBH₄-H₂O₂ and citrate heating reduction. The AgNR had a transverse and a longitudinal surface plasmon resonance (SPR) absorption peak at 338 nm and 480 nm. Meanwhile, two transverse and longitudinal SPR Rayleigh scattering (SPR-RS) peaks at 340 nm and 500 nm were observed firstly using common fluorescence spe...
متن کاملPILOT STUDY OF CONTACT SENSITIZATION TO RUBBER ALLERGENS AND BISPHENOL A AMONGST DENTAL STUDENTS MAYA GRIGORIEVNA LYAPINA1, ASSYA KRASTEVA2, MARIA DENCHEVA2, MARIANA TZEKOVA2, GEORGY NIKOLOV3, MARIELA YANEVA-DELIVERSKA4, and ANGELINA KISSELOVA-YANEVA2
Objectives: The aim of this study has been to evaluate the rate of contact sensitization to some rubber allergens and to bisphenol A (BPA) amongst students of dental medicine and dental patients. Material and Methods: A total of 50 participants were included in the study: 40 students of dental medicine exposed to the studied rubber allergens and BPA-based dental materials during the course of t...
