Development of Potent and Selective CK1α Molecular Glue Degraders.

Molecular glue degraders (MGDs) are small molecules that facilitate proximity between a target protein and an E3 ubiquitin ligase, thereby inducing target protein degradation. Glutarimide-containing compounds are MGDs that bind cereblon (CRBN) and recruit neosubstrates. Through explorative synthesis of a glutarimide-based library, we discovered a series of molecules that induce casein kinase 1 alpha (CK1α) degradation.

Flumequine, a fluoroquinolone in disguise.

Fluoroquinolone resistance in E. coli isolates from livestock in Europe remains high despite EMA restrictions on fluoroquinolone use in animals. However, flumequine, a quinolone not classified as a fluoroquinolone by various regulatory bodies, is still used in livestock in the Netherlands, Belgium, Greece and France.

Accuracy of flow volume estimation in the dilated aorta using 4D flow MRI: a pulsatile phantom study.

Aortic dilatation is a severe pathology that increases the risk of rupture and its hemodynamics could be accurately assessed by using the 4D flow cardiovascular magnetic resonance (CMR) technique but flow assessment under complex flow patterns require validation. The aim of this work was to develop ansystem compatible with CMR to assess the accuracy of volume flow measurements in dilated aortas.Two latex models, one with ascending and the other with abdominal aortic aneurysms were manufactured to ensure a constant and controlled net flow volume along the aortic length.

Substrate adaptors are flexible tethering modules that enhance substrate methylation by the arginine methyltransferase PRMT5.

Protein arginine methyltransferase (PRMT) 5 is an essential arginine methyltransferase responsible for the majority of cellular symmetric dimethyl-arginine (SDMA) marks. PRMT5 uses substrate adaptors such as pICln, RIOK1, and COPR5, to recruit and methylate a wide range of substrates. Although the substrate adaptors play important roles in substrate recognition, how they direct PRMT5 activity towards specific substrates remains incompletely understood.

Efficacy of a vein visualisation device for facilitating peripheral venous line placement in adult patients with sickle cell disease: A randomised clinical trial.

Background: Intravenous (IV) access is often required for the treatment of vaso-occlusive crises in patients with sickle cell disease, but can be particularly challenging due to recurrent venous damage. The AccuVein® device, uses near-infrared light technology to visualise veins for easier venepuncture.

Methods: A randomised, controlled trial of the efficacy of the AccuVeinAV400® device in the replacement of peripheral venous lines during a vaso-occlusive crisis was conducted at two centres in France.
