Objective: Asthma is a chronic inflammatory disease of the respiratory airways distinguished by edema and infiltration of inflammatory immune cells. To test our hypothesis about the anti-inflammatory effect of saffron, we examined effects of Crocus sativus (C. sativus) extract as a prophylactic anti-inflammatory agent in sensitized rats. Materials and Methods: To induce experimental asthma, rat...

OBJECTIVE To compare the skin prick test (SPT) with in vitro techniques (single and multiplex fluorescence enzyme-immunoassay [FEIA]) for detecting sensitization to profilin and lipid transfer protein (LTP). METHODS We retrospectively studied 181 patients with pollen and/or plant food allergy and 61 controls. SPT was performed with date palm profilin (Pho d 2) and peach LTP (Pru p 3), and spe...

a sensitive fluorometric method for the determination of deferiprone (dfp) based on the formation of a luminescent complex with tb3+ ions in aqueous solutions is reported. the maximum excitation and emission wavelengths were 295 and 545 nm, respectively. the effects of various factors on the luminescence intensity of the system were investigated and optimized, then under the optimum conditions,...

objective: the effects of natural adjuvants were examined on total and differential wbc counts in lung lavage of sensitized guinea pigs. materials and methods: in three sensitized groups of guinea pigs including: untreated sensitized animals (s), sensitized animals treated with adjuvant g2 (s+g2) and g2f (s+g2f) as well as non-sensitized group (c) (n=6 for each group), total and differential wb...

Methods The FRET donor, CFP, and FRET acceptor, YFP, were fused to aminoand carboxy-terminal ends of sGC subunits. After generation of recombinant baculovirus strains fluorescent tagged sGC subunits were co-expressed in Sf9cells. Fluorescent variants of sGC were analyzed in vitro in cytosolic fractions by sensitized emission FRET. In addition, fluorescent tagged sGC subunits were analyzed in vi...

The Perrin-Forster theory of sensitized fluorescence is extended by replacing the Coulomb interaction wth its relativistic counterpart, the Breit interaction. The transition matrix element is evaluated in a multipole expansion. The matrix element i s found to be modulated by the retardation factor eikR and to contain terms whch fall off only as l/R. The relation of these terms to spontaneous ph...

Abstract Lead halide perovskite materials have outstanding optical properties such as color purity and efficient fluorescence in the visible spectrum. However, toxicity of lead makes synthesis, processing, use disposal hazardous for humans environment. Therefore, exploration different containing transition metal Mn(II) fluoride anions might to more appealing alternatives towards sustainable env...
