Thermodynamic parameters and stoichiometries for the binding of anilinonaphthalenesulfonates to beta-cyclodextrin are obtained from steady-state fluorescence intensity and anisotropy measurements. Specifically, formation constant, enthalpy, and entropy values are obtained for complexes of beta-cyclodextrin with eight different substrate molecules at five(More)
Congenital cytomegalovirus (CMV) is frequently associated with active retinitis. In contrast, in the immunocompetent neonate with postnatally acquired CMV infection retinitis is rarely present and usually does not progress. We describe the case of an infant with postnatal CMV infection and active retinitis diagnosed at 20 days of life. Owing to the rapid(More)
PURPOSE To describe the morphofunctional findings in a 6-year-old child with a unilateral lesion of the temporal macula called "torpedo maculopathy" throughout a 1-year follow-up. METHODS Evaluation of retinal morphology and function was assessed by means of spectral-domain OCT scans, best-corrected visual acuity, full-field flash electroretinogram (ERG),(More)
The results of four diagnostic tests have been critically evaluated (xylosemia, serum Ig A level, steatorrhea, X-Ray of the digestic tract) in 80 cases of atrophy of the small intestinal mucosa discovered by biopsy, and in 20 cases in which the biopsy has proved normal. In the celiac subjects the best correlation with the biopsy was found with xylosemia(More)
Fluorescence lifetimes are reported for a series of anilinonaphthalene sulfonate (ANS) probe molecules complexed with β-cyclodextrin (β-CD). The fluorescence decay kinetics are recovered by multifrequency phase and modulation measurements in concert with a global analysis scheme. In all cases studied, a continuous Lorentzian distribution of lifetimes is(More)
