AI Article Synopsis
Article Abstract
RLIP76 (also known as RalBP1) is an effector for Ral small G proteins. RLIP76 is a multifunctional, multi-domain protein that includes a GTPase activating domain for the Rho family (RhoGAP domain) and a GTPase binding domain (GBD) for the Ral small G proteins. The juxtaposition of these two domains (GAP and GBD) may be a strategy employed to co-ordinate regulation of Rho family and Ral-controlled signalling pathways at a crossover node. Here we present the (1)H, (15)N and (13)C NMR backbone and sidechain resonance assignments of the GAP and GBD di-domain (31 kDa).

Staging of pediatric Hodgkin lymphoma is currently based on the Ann Arbor classification, incorporating the Cotswold modifications and the Lugano classification. The Cotswold modifications provide guidelines for the use of CT and MRI. The Lugano classification emphasizes the importance of CT and PET/CT in evaluating both Hodgkin lymphoma and non-Hodgkin lymphoma but focuses on adult patients.

An emulsion of silicone oil droplets in aqueous buffer produces a distinctive series of peaks or resonances in the side scatter histogram in a flow cytometer. As many as 12 peaks are observed in the violet-side scatter channel at 405 nm, with half that number observed in the blue side scatter channel at 488 nm. Using the index of refraction of the oil and buffer, the wavelength of light, and the collection angle and gain of the instrument, we assign the peaks to specific diameters at which Mie resonances occur.

Background: Magnetic resonance imaging (MRI) is a crucial non-invasive diagnostic tool for pediatric diseases, requiring patients to remain still, often with the use of sedatives. Midazolam and dexmedetomidine are commonly used for sedation in children, but their combined effect needs further study. This study aims to evaluate the safety and effectiveness of combining intranasal dexmedetomidine (ID) with oral midazolam (OM) in children undergoing MRI, and assess its clinical feasibility.

Background: In the DISCOMS (DISCOntinuation of disease-modifying therapies (DMTs) in multiple sclerosis (MS)) randomized clinical trial, we could not demonstrate that discontinuing MS DMTs in older, stable adults was not inferior to continuing DMTs. Relapses were rare in both groups, and most new disease activity was one to two new brain magnetic resonance imaging (MRI) lesions unassociated with clinical changes.
Objective/aims: Describe results of the DISCOMS extension study.
EmrE is a bacterial membrane-embedded multidrug transporter that functions as an asymmetric homodimer. EmrE is implicated in antibiotic resistance, but is now known to confer either resistance or susceptibility depending on the identity of the small molecule substrate. Here, we report both solution- and solid-state NMR assignments of S64V-EmrE at pH 5.
