Ayahuasca: farmacología, efectos agudos, potencial terapéutico y rituales
La ayahuasca es una preparación botánica alucinógena compuesta de Banisteriopsis caapi y Psychotria viridis que, tradicionalmente, ha sido consumida por grupos indígenas de la Amazonia. Este brebaje contiene el agonista serotoninérgico N,N-dimetiltriptamina (DMT) y alcaloides inhibidores de la monoaminooxidasa (IMAO) (harmina, harmalina y tetrahidroharmina). La literatura científica hasta el momento sugiere que la administración o ingesta aguda de la ayahuasca no es mal tolerada, incluso en aquellos casos en los que se ha registrado un uso crónico de la misma, no habiéndose informado sobre toxicidad en ningún estudio en humanos. No obstante, teniendo en cuenta la limitación del uso de una m…
Characterization of a medium size Xe/TMA TPC instrumented with microbulk Micromegas, using low-energy gamma-rays
NEXT-MM is a general-purpose high pressure (10 bar, $\sim25$ l active volume) Xenon-based TPC, read out in charge mode with an 8 cm $\times$8 cm-segmented 700 cm$^2$ plane (1152 ch) of the latest microbulk-Micromegas technology. It has been recently commissioned at University of Zaragoza as part of the R&D of the NEXT $0\nu\beta\beta$ experiment, although the experiment's first stage is currently being built based on a SiPM/PMT-readout concept relying on electroluminescence. Around 2 million events were collected during the last months, stemming from the low energy $\gamma$-rays emitted by a $^{241}$Am source when interacting with the Xenon gas ($\epsilon$ = 26, 30, 59.5 keV). The localized…
Study of the leptonic decays of the Z0 boson
Measurements are presented of the cross section ratios Rℓ = σℓ(e+e-→ℓ+ℓ -)/σhh(e+e-→hadrons) for ℓ = e, μ and τ using data taken from a scan around the Z0. The results are Re = (5.09±0.32±0.18)%, Rμ = (4.96±0.35±0.17)% and Rτ,=(4.72±0.38± 0.29)% where, for the ratio Re, the t-channel contribution has been subtracted. These results are consistent with the hypothesis of lepton universality and test this hypothesis at the energy scale s ∼ 8300 GeV2. The absolute cross sections σℓ(e+e-→ℓ +ℓ-) have also been measured. From the cross sections the leptonic partial widths Γe = (83.2±3.0±2.4) MeV, (ΓeΓμ) 1/2=(84.6±3.0±2.4) MeV and (ΓeΓτ) 1/2=(82.6±3.3±3.2) MeV have been extracted. Assuming lepton un…
Quantum chemical structure-activity relationships on β-carbolines as natural monoamine oxidase inhibitors
The electron density and the molecular electrostatic potential of the β-carbolines are studied using ab initioSTO-3G wave functions. The analysis was done from the point of view of a previous model built with monoamine oxidase substrates and irreversible inhibitors. The results confirm the usefulness of the model and make it possible to propose new precision to the molecular electrostatic potential patterns needed to have monoamine oxidase inhibitory activity.
