Introduction: Limited data exist regarding treatment patterns and symptom burden of patients with anemia of chronic kidney disease (CKD) in the Middle East, South Africa, and Türkiye.
Methods: This real-world study explored clinical characteristics, symptom burden, and treatment patterns of patients with anemia of CKD living in the Middle East, South Africa, and Türkiye. Physician and patient perceptions of treatment were captured via cross-sectional surveys; patients' clinical characteristics were recorded by retrospective review of medical records.
Molecular Mechanism of Unexpected Metal-Independent Hydroxyl Radical Production by Mercaptotriazole and HO.

It is well known that hydroxyl radical (OH) can be largely produced either through the classic iron-mediated inorganic-Fenton system or our recently discovered haloquinones/HO organic-Fenton-like system, but rarely produced via thiol compounds. Here, unexpectedly, we found that OH can be unequivocally generated by incubation of HO and mercaptotriazole (MTZ), a typical heterocyclic thiol which has been used as an environmentally friendly corrosion inhibitor for mild steel. By the complementary applications of HPLC-MS and oxygen-18 isotope-labeling method, MTZ-derived sulfenic (MTZ-SOH) and sulfinic acids were detected and identified as transient intermediates, and sulfonic acid as final products.

Recently, the activation of chlorine dioxide (ClO) by metal(oxide) for soil remediation has gained notable attention. However, the related activation mechanisms are still not clear. Herein, the variation of iron species and ClO, the generated reactive oxygen species, and the toxicity of the degradation intermediates were explored and evaluated with nanoscale zero-valent iron (nFe) being employed to activate ClO for soil polycyclic aromatic hydrocarbon (PAH) removal.

Advanced magnetic resonance imaging (MRI) techniques are transforming the study of movement disorders by providing valuable insights into disease mechanisms. This narrative review presents a comprehensive overview of their applications in this field, offering an updated perspective on their potential for early diagnosis, disease monitoring, and therapeutic evaluation. Emerging MRI modalities such as neuromelanin-sensitive imaging, diffusion-weighted imaging, magnetization transfer imaging, and relaxometry provide sensitive biomarkers that can detect early microstructural degeneration, iron deposition, and connectivity disruptions in key regions like the substantia nigra.
