AI Article Synopsis
- The iodine-131 solution's activity was precisely measured using two methods: the 4πβ-γ coincidence and the 4πγ counting technique.
- A calibrated solution was created to produce point sources, with a preliminary step of adding AgNO3 to minimize iodine loss.
- Gamma-ray spectrometry was employed to determine the emission intensities of 15 gamma-rays and two K X-rays from xenon, achieving a relative uncertainty of 0.8% for the main emissions.
Article Abstract
The activity per unit mass of an iodine-131 solution was absolutely standardized by both the 4πβ-γ coincidence method and the 4πγ counting technique. The calibrated solution was used to prepare point sources after a preliminary deposit of AgNO3 to prevent the loss of volatile iodine. Relative and absolute photon emission intensities of 15 sgamma-rays and those of the two K X-rays of xenon were determined by gamma-ray spectrometry, with relative uncertainties of 0.8% for the three main emissions.

Defining the Zone of Acute Peripheral Nerve Injury Using Fluorescence Lifetime Imaging in a Crush Injury Sheep Model.

Purpose: Current technologies to define the zone of acute peripheral nerve injury intraoperatively are limited by surgical experience, time, cumbersome electrodiagnostic equipment, and interpreter reliability. In this pilot study, we evaluated a real-time, label-free optical technique for intraoperative nerve injury imaging. We hypothesize that fluorescence lifetime imaging (FLIm) will detect a difference between the time-resolved fluorescence signatures for acute crush injuries versus uninjured segments of peripheral nerves in sheep.

Technetium-99m (Tc-99m) is the most employed radionuclide in nuclear imaging diagnostics worldwide for many diseases. The ideal physiochemical properties of Tc-99m (such as half-life and pure gamma energy) make it favorable for Single Photon Emission Computed Tomography (SPECT). In this study, we aim to expand the utilization of Tc-99m radiopharmaceutical toward prostate cancer diagnostics which is currently no FDA approved products and has been intensively examined for a potential candidate.

The Gulf States are home to industries emitting styrene, benzene, toluene, ethylbenzene, and xylenes (SBTEX). Presently, adverse health effects of ambient SBTEX exposure in highly polluted regions, such as the Gulf States, must be evaluated. Epidemiologists, however, are limited by inadequate estimates of ambient SBTEX.

Ln-MOFs, composed of lanthanide ions and functional organic ligands, are porous materials with tunable structures and unique luminescent properties. However, the interplay between ligand AIE properties and the framework's "antenna effect" on MOF morphology is understudied. Here, Tb-D-Cam-TPTB was synthesized via solvothermal method using TPTB (persulfurated arene) as the primary ligand, D-Cam as the auxiliary ligand, and Tb3+ as the metal ion.

Over the past 20 years, urbanization of Shandong Province has strongly supported the rapid growth and sustained transformation of economy, however, this region has suffered from serious atmospheric pollution due to intense human activity. Identifying and qualifying the spatio-temporal variation of air pollution and its driving forces of Shandong Province would help in the formulation of effective mitigation policies. A deep understanding of the coupling relationship between air quality and socioeconomic drivers was essential for evaluating the quality of urbanization and long term sustainability.
