Background: Monoclonal gammopathy (MG) has been reported in association with numerous neurological disorders but the spectrum of MG-associated myopathies remains poorly described.
Objective: To report a newly acquired myopathy associated with MG.
Methods: Three adult patients with the same phenotype from two French referral centers were prospectively analyzed.
Specialized or secondary metabolites are small molecules of biological origin, often showing potent biological activities with applications in agriculture, engineering and medicine. Usually, the biosynthesis of these natural products is governed by sets of co-regulated and physically clustered genes known as biosynthetic gene clusters (BGCs). To share information about BGCs in a standardized and machine-readable way, the Minimum Information about a Biosynthetic Gene cluster (MIBiG) data standard and repository was initiated in 2015.

- Streptomyces scabiei causes common scab in root and tuber crops and exhibits antimicrobial properties influenced by peptone levels.
- Comparative metabolomics revealed that increased peptone led to enhanced production of siderophores, which are molecules that help inhibit the growth of competing microorganisms by sequestering iron.
- The study also found that different nitrogen sources can trigger siderophore production, impacting competition for iron among soil-dwelling microbes and possibly affecting plant pathogens.
Article Synopsis
- A study compared the effectiveness and safety of infliximab and cyclophosphamide as induction therapies for severe Behçet's syndrome involving major vascular or CNS issues.
- Infliximab showed a higher complete response rate (81%) compared to cyclophosphamide (56%), indicating it may be more effective.
- Additionally, infliximab had fewer adverse events (29.6%) compared to cyclophosphamide (64%), suggesting it may also be safer for patients.
Matrix-assisted laser desorption/ionization (MALDI) mass spectrometry imaging (MSI) is a label-free technique, producing images where pixels contain mass spectra. The technique allows the visualization of the spatial distribution of (bio)molecules from metabolites to proteins, on surfaces such as tissues sections or bacteria culture media. One particularly exciting example of MALDI-MSI use rests on its potential to localize ionized compounds produced during microbial interactions and chemical communication, offering a molecular snapshot of metabolomes at a given time.
