Relaxivity of Gadobutrol and Gadoteric Acid in Cerebrospinal Fluid at 3T

Magnetic Resonance in Medicine, Volume 95, Issue 6, Page 3409-3415, June 2026.
ABSTRACT Purpose The aim was to estimate T1 relaxivity of gadobutrol and gadoteric acid in cerebrospinal fluid (CSF) at 3T, to support research on CSF‐flow and the glymphatic system in humans utilizing T1 mapping after intrathecal injection. Methods Using a phantom, relaxivity was estimated for gadobutrol and gadoteric acid in lumbar CSF and an ...

CFD‐Based and Control‐Oriented Modeling of a Counterflow Heat Exchanger With Utilization of Parameter Identification

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT Counterflow heat exchangers (CHXs) thermally couple consumers and producers to a district heating network (DHN). Fluctuating loads and control actions naturally lead to unsteady operation conditions of the network and its components, posing a challenge for DHN models and CHX parameterizations based on Nusselt correlations that assume steady ...

Stabilizing Plasmodium falciparum proteins for small molecule drug discovery

Protein Science, Volume 35, Issue 6, June 2026.
Abstract Early‐stage drug discovery relies on the availability of stable protein for reliable biophysical characterization of ligand binding. However, many Plasmodium falciparum proteins are challenging to produce in heterologous systems, which limits their experimental utility.

Impact of software tools and kinetic model selection on myocardial blood flow and flow reserve quantitation in 13N‐ammonia PET

Journal of Applied Clinical Medical Physics, Volume 27, Issue 5, May 2026.
Abstract Background Quantitative assessment of myocardial perfusion using 13N‐ammonia PET with compartmental modeling enables evaluation of myocardial flow reserve (MFR) and prediction of patient prognosis. However, the reliability of these assessments can depend on the analytical methods used for quantitation.
