The DNA Recognition Motif of GapR Has an Intrinsic DNA Binding Preference towards AT-rich DNA

Molecules, 2021
The nucleoid-associated protein GapR found in Caulobacter crescentus is crucial for DNA replication, transcription, and cell division. Associated with overtwisted DNA in front of replication forks and the 3′ end of highly-expressed genes, GapR can ...

Comparison of Image Quality and Radiation Dose Between Single-Energy and Dual-Energy Images for the Brain With Stereotactic Frames on Dual-Energy Cerebral CT

Frontiers in Radiology, 2022
BackgroundPreoperative stereotactic planning of deep brain stimulation (DBS) using computed tomography (CT) imaging in patients with Parkinson's disease (PD) is of clinical interest. However, frame-induced metal artifacts are common in clinical practice,

Distinct activation mechanisms of β-arrestin-1 revealed by 19F NMR spectroscopy

Nature Communications, 2023
β-Arrestins (βarrs) are functionally versatile proteins that play critical roles in the G-protein-coupled receptor (GPCR) signaling pathways. While it is well established that the phosphorylated receptor tail plays a central role in βarr activation ...

Design, Characterization and Molecular Modeling of New Fluorinated Paramagnetic Contrast Agents for Dual ¹H/¹⁹F MRI

Magnetochemistry, 2020
One major goal in medical imaging is the elaboration of more efficient contrast agents (CAs). Those agents need to be optimized for the detection of affected tissues such as cancers or tumors while decreasing the injected quantity of agents.
