Parahydrogen Polarization in Reverse Micelles and Application to Sensing of Protein-Ligand Binding.

J Am Chem Soc

December 2024

Chemistry Department, Texas A&M University, 3255 TAMU, College Station, Texas 77843, United States.

A medium containing reverse micelles supports non-hydrogenative parahydrogen induced polarization (nhPHIP) in the organic phase while solubilizing a protein in the aqueous phase. Strongly enhanced NMR signals from iridium hydride complexes report on a ligand, 4-amino-2-benzylaminopyrimidine, which crosses the phase boundary and interacts with the thiaminase protein TenA. The calculation of binding equilibria reveals a of 39.

Background: B-cell acute lymphoblastic leukemia (B-cell ALL) is the most common childhood cancer. Despite a high overall cure rate, relapsed B-cell ALL remains a leading cause of cancer-related death among children. The addition of the bispecific T-cell engager molecule blinatumomab (an anti-CD19 and anti-CD3 single-chain molecule) to therapy for newly diagnosed standard-risk (as defined by the National Cancer Institute) B-cell ALL in children may improve outcomes.

Precisely assessing nectin-4 expression in tumors is important in identifying patients who may benefit from nectin-4-targeted therapies. In our previous work, we developed a bicyclic peptide-based nectin-4-targeting radiotracer Ga-N188 and validated its nectin-4 detection efficacy. However, the relatively short half-life and low positron emission rate of Ga limit its further application.

Stylometry for real-world expert coders: a zero-shot approach.

PeerJ Comput Sci

November 2024

LTCI, Télécom Paris, Institut Polytechnique de Paris, Paris, France.

Code stylometry is the application of stylometry techniques to determine the authorship of software source code snippets. It is used in the industry to address use cases like plagiarism detection, code audits, and code review assignments. Most works in the code stylometry literature use machine learning techniques and (1) rely on datasets coming from coding competition for training, and (2) only attempt to recognize authors present in the training dataset (in-distribution authors).

Background: White matter hyperintensities (WMHs) are established structural imaging markers of cerebral small vessel disease. The pathophysiologic condition of brain tissue varies over the core, the vicinity, and the subtypes of WMH and cannot be interpreted from conventional magnetic resonance imaging. We aim to improve our pathophysiologic understanding of WMHs and the adjacently injured normal-appearing white matter in terms of microstructural and microvascular alterations using quantitative magnetic resonance imaging in patients with sporadic and genetic cerebral small vessel disease.

Impaired spinal GABAergic inhibitory neuronal system is one popular target for developing new drugs or procedures for treatment of neuropathic pain, but effective and transferable methods are still lacking. We designed an assembled, temperature sensitive and sustained releasing hydrogel to repair the impaired GABAergic neural system by reversing imbalance of glutamic acid (Glu) and γ-aminobutyric acid (GABA) and healing impaired Cl extrusion capacity of neurons. Hydrogel solution is a mixture of pluronic F-127, recombinant glutamate decarboxylase 67 (rGAD67) protein and CLP257, a K-Cl cotransporter isoform 2 (KCC2) enhancer.

Background: To combat the high prevalence of physical inactivity among children, there is an urgent need to develop and implement real-world interventions and policies that promote physical activity (PA) and reduce sedentary behaviour (SB). To inform policy makers, the current body of evidence for children's PA/SB interventions needs to be translated.

Objectives: The current systematic review and meta-analysis aimed to identify modifiable determinants of device-measured PA and SB targeted in available intervention studies with randomized controlled trial (RCT) and controlled trial (CT) designs in children and early adolescents (5-12 years) and to quantify the effects of the interventions within their respective settings on the determinants of PA/SB and the outcomes PA and SB.

Genome Engineering, Discovery Sciences, BioPharmaceuticals R&D Unit, AstraZeneca, Gothenburg, Sweden. Electronic address:

Gene editing strategies to safely and robustly modify the Alzheimer's disease-associated APOE4 isoform are still lacking. Prime editing (PE) enables the precise introduction of genetic variants with minimal unintended editing and without donor templates. However, it requires optimization for each target site and has not yet been applied to APOE4 gene editing.

The steatotic liver disease burden paradox: unravelling the key role of alcohol.

Nat Rev Gastroenterol Hepatol

December 2024

Centre for Liver Research, Department of Gastroenterology and Hepatology, Odense University Hospital, Odense, Denmark.

The classification of steatotic liver disease (SLD) has evolved, incorporating all conditions characterized by hepatic lipid accumulation. SLD represents a continuum of disorders that are shaped by the dynamic factors of alcohol intake and cardiometabolic risk factors. This updated classification has profound implications for both the management and research of SLD, especially with the new distinct category of patients with both metabolic and alcohol-related liver disease.

Department of Diagnostic and Interventional Neuroradiology (G.B., M.M., M.B., H.K., L.W., C.H., J.F., L.M.), University Medical Center Hamburg-Eppendorf, Hamburg, Germany.

Background: A potential benefit of mechanical thrombectomy for patients with distal medium vessel occlusions is currently being investigated in randomized trials. Computed tomography perfusion imaging has not yet been tested as a method to guide mechanical thrombectomy for distal medium vessel occlusions. The purpose of this study was to assess penumbral imaging as an imaging-based method for triaging patients with ischemic stroke and acute M2-middle cerebral artery occlusion.

Synthetic receptors that mediate antigen-dependent cell responses are transforming therapeutics, drug discovery and basic research. However, established technologies such as chimeric antigen receptors can only detect immobilized antigens, have limited output scope and lack built-in drug control. Here we engineer synthetic G-protein-coupled receptors (GPCRs) that are capable of driving a wide range of native or non-native cellular processes in response to a user-defined antigen.
