Intestinal alkaline phosphatases (IALPs) are widely expressed in the brush border of epithelial cells of the intestinal mucosa. Although their physiologic role is unclear, they are very significant when it comes to the release of bioactive parent from orally dosed phosphate prodrugs. Such prodrugs can be resistant to cleavage by IALP, or alternatively undergo rapid cleavage leading to the relea...

Searching for Exotic Mesons in E

Exclusive production of heavy mesons in e+e- annihilation.

Within the framework of a particular model for meson production, we have performed a perturbative QCD analysis for exclusive pair production of heavy mesons. Analytic calculations of angular distributions for pseudoscalar-pseudoscalar, vector-pseudoscalar and vector-vector mesons are presented. Numerical estimates of the cross section, angular distributions and forward-backward asymmetry for va...

Vector mesons in nuclear μ − − e − conversion

We study nuclear μ− − e− conversion in the general framework of an effective Lagrangian approach without referring to any specific realization of the physics beyond the standard model (SM) responsible for lepton flavor violation (Lf / ). We show that vector meson exchange between lepton and nucleon currents plays an important role in this process. A new issue of this mechanism is the presence o...

Pii: S1386-1425(02)00004-5

The fluorescence spectroscopy of 7-azaindole (In) incorporated in DNA oligonucleotides is investigated. Incorporation of In into DNA oligonucleotides is accomplished through standard solid-phase phosphoramidite chemistry. Fluorescence emission of the In chromophore shifts slightly to the red (from 386 nm to 388 nm) upon glycosylation at the N−1 position, but its relative fluorescence quantum yi...
