We have studied the one-meson radiative tau decays À ! À ðK À Þ, computing the structuredependent contributions within a Lagrangian approach based on the large-N C limit of QCD that ensures the proper low-energy limit dictated by chiral symmetry. Upon imposing the short-distance QCD constraints to the form factors, we are able to predict the structure-dependent radiation without any free parameter and, therefore, the relevant observables for the decay À ! À : the photon energy spectrum, the invariant mass spectrum of the meson-photon system, and the integrated decay rate. We also discuss the remaining uncertainties in these observables for the À ! K À decay. According to our results, the present facilities could detect these rare decays for the first time in the near future, allowing for a stringent test of our predictions.

“…The structure and function of most cysteine-containing proteins depend dramatically on the oxidation state of the SH groups. There is evidence that reagents which oxidize SH groups mobilize Ca 2+ thereby increasing [Ca2+]i on platelets, hepatocytes, oocytes and insulin-secreting cells [11,[27][28][29]. In mouse pancreatic acinar cells, thimerosal mobilised Ca 2+ from the InsP3-sensitive intracellular pool and caused repetitive Ca 2+ spikes [13].…”

Modulation of the agonist-specific cytosolic Ca 2+ o~cillatory pattern by thimerosal has been investigated in single pancreatic acinar cells using patch-clamp perforated whole-cell recording to measure the calcium-dependent chloride current (lcl(c~÷)). 1 gM thimerosal, which falls to evoke Ca 2+ oscillation alone, clearly changed the pattern of Ca 2+ oscillation from pulsatile spikes (evoked by low concentrations of activators) to sinusoidal or transient oscillations. The mimetic action of thimerosal was independent of extracellniar Ca 2+, was blocked by extracellular application of dithiothreitol or 10 mM caffeine, as well as by internal perfusion with heparin; but was unaffected by ruthenium red. We conclude that thimerosal modulates the agonist-specific cytosolic Ca 2+ oscillatory patterns mediated by sensitizing the InsP3-indnced Ca 2+ release.

We calculate the radiative corrections to the decays τ → Mν τ and π → lν l , where the meson M is M = π or K and the lepton l is l = e or µ. We perform a complete calculation, which includes internal bremsstrahlung and structure dependent radiation in the radiative decays and point meson, hadronic structure dependent and short distance contributions in the virtual corrections. Our result for the radiative correction to the ratio Γ(τ → πν τ (γ))/Γ(π → µν µ (γ)) is δR τ /π = 0.16 +0.09 −0.14 %. For the ratio Γ(τ → Kν τ (γ))/Γ(K → µν µ (γ)), we obtain δR τ /K = 0.90 +0.17 −0.26 %. For completeness we have also calculated the ratio of the electronic and muonic decay modes of the pion.
