Peptide R23, consisting of residues 1091-1115 of bovine interphotoreceptor retinoid-binding protein (IRBP), had some unusual immunologic properties in Lewis rats. The peptide induced experimental autoimmune uveoretinitis and pinealitis in these rats, but only at high doses. The minimal immunopathogenic dose was found to be 100 nmol/rat. On the other hand, R23 was highly immunogenic in Lewis rat...

Aims. We verify whether the O/H abundances of galaxies can be derived from the equivalent width (EW) R23 instead of the extinctioncorrected flux R23, and eventually propose a method of improving the reliability of this empirical method, which is often used for the non-flux calibrated spectra of galaxies. Methods. We select 37,173 star-forming galaxies from the Second Data Release of the Sloan D...

In this study, energy analysis of a double-stage Organic Rankine Cycle (ORC) was performed using the Engineering Equation Solver program (EES). first and second stages, eight different organic working fluids (R134a, R410a, RC318, R407c, R22, R23, R116, R218) were used in pairs for certain temperature limits. Choosing suitable refrigerant or pair is crucial ORC’s high thermal efficiency net work...

The heterokaryotic and vegetative diploid phases of Colletotrichum lindemuthianum are described using nutritional and biochemical markers. Nitrate non-utilizing mutants (nit), derived from R2047, R89, R73, R65, and R23 isolates, were paired in all possible combinations to obtain heterokaryons. Although pairings R2047/R89, R2047/R73, R65/R73, and R73/R23 showed complete vegetative incompatibilit...

In this paper, a new combined system is proposed for recovering thermal energy at medium temperature using cascade organic Rankine cycle to feed refrigeration cycle. Energy and exergy analysis applied the determine its performance different working fluids under same operating conditions taking into account effect of some parameters selection on performance. The pair fluid

The present work deals with thermodynamic analysis of cascade refrigeration system using ozone friendly refrigerants pair R507A and R23. R507A is azeotropic mixture composed of HFC refrigerants R125/R143a (50%/50% wt.). R23 is a single component HFC refrigerant used as replacement to CFC refrigerant R13 in low temperature applications. These refrigerants have zero ozone depletion potential and ...

BACKGROUND AND OBJECTIVE The mechanism inducing either inflammation or tolerance to orally administered food allergens remains unclear. To investigate this we analyzed mouse models of food allergy (OVA23-3) and tolerance (DO11.10 [D10]), both of which express ovalbumin (OVA)-specific T-cell receptors. METHODS OVA23-3, recombination activating gene (RAG)-2-deficient OVA23-3 (R23-3), D10, and R...
