Generation of two isogenic human iPSC lines (ZIPi013-B-1, ZIPi013-B-2) carrying a CRISPR/Cas9-mediated deletion of TRPM4.

Two isogenic hiPSC lines, ZIPi013-B-1 and ZIPi013-B-2, were generated by CRISPR/Cas9-mediated indels in the TRPM4 gene of the previously published ZIPi013-B. TRPM4 belongs to the evolutionarily conserved family of transient receptor potential (TRP) channels. It is expressed ubiquitously and its activity is regulated by intracellular calcium binding, changes in membrane potential, phosphoinositide lipids in the plasma membrane and the local concentration of cytoplasmic ATP and ADP.

Performance and Interpretation of Lung Scintigraphy: An Evaluation of Current Practices in Australia, Canada, France, Germany, and United States.

Purpose: Although ventilation/perfusion (V/Q) scintigraphy is a widely used imaging test, different options are possible for the acquisition and interpretation of the scan. The aim of this study was to assess current practices regarding the use and interpretation of lung scintigraphy in various clinical indications.

Patients And Methods: An online survey comprising 25 questions was sent to nuclear medicine departments in Australia, Canada, France, Germany, and United States between 2022 and 2023.

Method for the generation of oscillating scattered light intensities for the determination of a particle property vector.

We present a method for particle characterization by analyzing the light scattering from a single particle using a shaped light beam, whereby the polarization of the light beam is modulated in time. As a result, light with oscillating polarization is scattered by the particle, which offers enhanced signal evaluation benefits. First, the frequency of the high-frequency component provides an improved differentiation of the signal within a continuous flow.

Myocardial Perfusion SPECT and ATTR imaging 2021 in Germany: Results of the 9th Survey.

Aim: This paper presents the results of the 9th survey of myocardial perfusion SPECT (MPS) from the reporting year 2021.

Methods: 218 questionnaires (131 practices (PR), 58 hospitals (HO), 29 university hospitals (UH)) were evaluated. Results of the last survey 2018 are set in squared brackets.

Modulation of biliverdin dynamics and spectral properties by Sandercyanin.

Biliverdin IX-alpha (BV), a tetrapyrrole, is found ubiquitously in most living organisms. It functions as a metabolite, pigment, and signaling compound. While BV is known to bind to diverse protein families such as heme-metabolizing enzymes and phytochromes, not many BV-bound lipocalins (ubiquitous, small lipid-binding proteins) have been studied.
