In this paper we consider transformations of sequences of orthogonal polynomials associated with a Hermitian linear functional L using spectral transformations of the corresponding C-function FL. We show that a rational spectral transformation of FL with polynomial coefficients is a finite composition of four canonical spectral transformations.

We investigated the electronic properties of N(5)-ethyl flavinium perchlorate (Et-Fl(+)) and compared them to those of its parent compound, 3-methyllumiflavin (Fl). Absorption and fluorescence spectra of Fl and Et-Fl(+) exhibit similar spectral features, but the absorption energy of Et-Fl(+) is substantially lower than that of Fl. We calculated the absorption signatures of Fl and Et-Fl(+) using...

A patient with a normal blood hemoglobin was found to be heterozygous for a new level, but with evidence of brisk hemolfl-chain mutation and fl-thalassemia. All ysis, was found to have an unstable of the hemoglobin in his red cells was of hemoglobin with a left-shifted oxygen the abnormal type, designated hemodissociation curve. Two sisters of the paglobin Duarte, and was shown to contain tient...

glutathione, considered to be the master antioxidant (ao), is the most-important redox regulator that controls in therapeutic considerations for the adjunctive use of glutathione in management of periodontitis, in limiting the tissue damage associated with oxidative stress, and enhancing wound healing cannot beunderestimated, but need to be evaluated further through multi-centered randomized co...
