Influence on the Chemistry Quenching of Low Level Tritium in Natural Water by the Solid Polymer Electrolysis Enrichment Method

open access: yesYankuang ceshi, 2016
The Solid Polymer Electrolysis (SPE) enrichment method is a practical way to measure low level tritium (1 μS/cm) or acidification pH samples. For water samples the impurity ions taken by the polymer film, can be used to adjust the pH value with tiny ...

Imatinib decreases germ cell survival and germline stem cell proliferation in rodent testis ex vivo and in vitro

open access: yesAndrology, EarlyView.
Abstract Background Imatinib and dasatinib are tyrosine kinase inhibitors (TKIs) increasingly used to treat several diseases in both children and adults at fertile age. We have previously shown that imatinib has adverse effects on developing testis, and imatinib‐treated male patients have been reported to have reduced sperm counts.

Advancements in radiocarbon dating: An overview of its impact on Mexican archaeology

open access: yesArchaeometry, EarlyView.
Abstract In this article, we provide a concise historical summary tracing the evolution of radiocarbon dating techniques in Mexico and Central America. We explore the contributions of early pioneers who first employed radiocarbon dating methods, leading to the establishment of a Mexican accelerator mass spectrometry laboratory. The study highlights its

Neutron Energy Spectrum Measurements with a Compact Liquid Scintillation Detector on EAST [PDF]

open access: yesarXiv, 2013
A neutron detector based on EJ301 liquid scintillator has been employed at EAST to measure the neutron energy spectrum for D-D fusion plasma. The detector was carefully characterized in different quasi-monoenergetic neutron fields generated by a 4.5 MV Van de Graaff accelerator.

Ligand bias and inverse agonism on 5‐HT2A receptor‐mediated modulation of G protein activity in post‐mortem human brain

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Whereas biased agonism on the 5‐HT2A receptor has been ascribed to hallucinogenic properties of psychedelics, no information about biased inverse agonism on this receptor is available. In schizophrenia, increased 5‐HT2A receptor constitutive activity has been suggested, highlighting the therapeutic relevance of inverse ...

Radioassay by gas-liquid chromatography of lipids labeled with carbon-14

open access: yesJournal of Lipid Research, 1962
A method for radioassay of carbon-I4 labeled substances analyzed by gas-liquid chromatography is described. The column effluent is automatically fractionated by condensing the vapor in a series of cartridges filled with anthracene crystals coated with ...
