Using programmable infusion pump in avian species – a validation methodology in geese

Wildlife Biology, EarlyView.
Wildlife face anthropogenic and natural stressors that affect their physiology and behaviour. The activity of the hypothalamic–pituitary–adrenal axis and glucocorticoid (GC) production is intrinsically linked with energy regulation and environmental stressors.

Application of Digital Anti-Coincidence Counting Method for Primary Activity Determination of 59Fe

Atom Indonesia, 2019
As a radiopharmaceutical, the use of 59Fe is classified as a high pharmaceutical risk product. Therefore, a standard reference for activity measurement of 59Fe is necessary to ensure its metrological aspect. This paper describes an alternative method for

Time-Resolved Liquid Scintillation Counting [PDF]

Radiocarbon, 1990
Historically, scientists who perform low-level measurements of 14C for age dating, and 3H2O for environmental contamination, have purchased or constructed highly specialized instruments to quantitate low-level radionuclides using a general-purpose liquid-scintillation analyzer (LSA).

Phase and absorbance retrieval in X‐ray holographic microscopy under weak illumination using physics‐driven neural networks

Journal of Synchrotron Radiation, EarlyView.
A physics‐driven deep learning model enables single‐shot retrieval of 3D phase and absorbance from shot‐noise‐limited hard X‐ray holograms. Validated on both synthetic and experimental data, it provides robust reconstruction under weak illumination.X‐ray holographic microscopy is a three‐dimensional (3D) imaging technique for nanoscale‐resolution ...

Advances in Kinetic Isotope Effect Measurement Techniques for Enzyme Mechanism Study

Molecules, 2013
Kinetic isotope effects (KIEs) are a very powerful tool for investigating enzyme mechanisms. Precision of measurement is the most important factor for KIE determinations, especially for small heavy atom KIEs.

Hydrochlorides, hydrates, hydronitrate, and an unanticipated hydrolysis product of famotidine

Acta Crystallographica Section C, EarlyView.
The structures of a new polymorph of famotidine hydrochloride, a famotidine hydrochloride hydrate, a new hydronitrate salt of famotidine, and an unexpected hydrolyzed complex of famotidine are reported. The famotidine hydrochloride hydrate and the hydrolyzed famotidine hydrochloride have Z′ values of 2 and 4, respectively.This article contributes to ...
