Background: Multiple sclerosis (MS) is a chronic autoimmune disease damaging the central nervous system. Diminished inflammatory disease activity (DA) as people with MS (pwMS) age motivated randomized clinical trials assessing disease-modifying therapy (DMT) discontinuation in older pwMS given the concern for risks outweighing benefits. This study aims to examine whether peripheral production of Myelin Basic Protein (MBP)-driven cytokine responses mediate the aging-associated decline in MS inflammatory DA.

Background: Relaxation time provides invaluable insights into the molecular structure, interactions, and dynamics in nuclear magnetic resonance spectroscopy. However, conventional relaxation-time measurement techniques produce inaccurate relaxation times when the spectral peaks overlap because of the narrow chemical-shift range and J-coupled splitting. While the combination of pure-shift methods can solve this issue, they are not widely used due to their inherent drawbacks such as low sensitivity and long acquisition time.

Advances in X-ray crystallography and cryogenic electron microscopy (cryo-EM) offer the promise of elucidating functionally relevant conformational changes that are not easily studied by other biophysical methods. Here we show that 3D variability analysis (3DVA) of the cryo-EM map for wild-type (WT) human asparagine synthetase (ASNS) identifies a functional role for the Arg-142 side chain and test this hypothesis experimentally by characterizing the R142I variant in which Arg-142 is replaced by isoleucine. Support for Arg-142 playing a role in the intramolecular translocation of ammonia between the active site of the enzyme is provided by the glutamine-dependent synthetase activity of the R142 variant relative to WT ASNS, and MD simulations provide a possible molecular mechanism for these findings.

Article Synopsis
  • The study assessed the effectiveness of combining repetitive transcranial magnetic stimulation (rTMS) with repetitive peripheral magnetic stimulation (rPMS) to improve upper limb motor function in stroke patients.
  • After reviewing 9 randomized controlled trials with 483 participants, results indicated significant improvements in motor function, daily living abilities, and reduced spasticity for patients receiving the combined treatment compared to using rTMS or conventional therapy alone.
  • The findings suggest that this combined approach may enhance recovery in stroke patients, but the evidence is considered low-quality. More high-quality research is needed to confirm these results.

In this work, a synthetical glycan fingerprinting strategy using a multiple heart-cut two-dimensional liquid chromatography system linked to mass spectrometry (MHC 2D LC-MS) was developed to analyze enoxaparin, a widely used low molecular weight heparin (LMWH). Glycans from an enoxaparin standard were prepared offline based on size, and the derived tetra-, hexa-, octa- and decasaccharides were profiled using a qualitative analytical platform. Strong anion exchange chromatography (SAX) was employed as the first-dimensional chromatography (D) to separate glycans of the same size but with different charges or sequences, while size exclusion chromatography (SEC) was used in the second dimension (D) for desalting before MS analysis.

Article Synopsis
  • Recent research suggests that the coagulation system in mammals helps defend against bacterial infections by trapping bacteria in clots and producing antimicrobial peptides.
  • A study identified a new bacterial exotoxin called F6W77, which contains five Kunitz-type domains that have similarities to animal but not plant proteins.
  • Evaluation of these Kunitz-domain peptides revealed that KABP1 and KABP5 effectively inhibit specific coagulation factors, indicating a new mechanism by which bacteria may evade the host's defense system.
