Autoimmune Encephalitis and Paraneoplastic Neurologic Syndromes: A Nationwide Study on Epidemiology and Antibody Testing Performance.

Background And Objectives: Autoimmune encephalitis (AIE) and paraneoplastic neurologic syndromes (PNSs) encompass a heterogeneous group of antibody-associated disorders. Both the number of syndromes and commercially available antibody tests have increased considerably over the past decade. High-quality population-based data on epidemiology of these disorders and real-world performance of antibody tests are needed.

Subcortical plaques and inflammation reflect cortical and meningeal pathologies in progressive multiple sclerosis.

It remains elusive whether lesions and inflammation in the sub/juxtacortical white matter reflect cortical and/or meningeal pathologies. Elucidating this could have implications for MRI monitoring as sub/juxtacortical lesions are detectable by routine MRI, while cortical lesions and meningeal inflammation are not. By large-area microscopy, we quantified total and mixed active plaque loads along with densities and sizes of perivascular mononuclear infiltrates (infiltrates) in the sub/juxtacortical white matter ≤2 mm from the cortex, intra-cortically and in the meninges.

Metabolic Reprogramming of Phospholipid Fatty Acids as a Signature of Lung Cancer Type.

Lung cancer is one of the leading causes of cancer-related mortality. Non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC) differ in aggressiveness, proliferation speed, metastasis propensity, and prognosis. Since tumor cells notably change lipid metabolism, especially phospholipids and fatty acids (FA), this study aimed to identify FA alterations in lung cancer tissues.

Relationship between potentially toxic elements and macrophyte communities in the Sava river.

Freshwater ecosystems are at significant risk of contamination by potentially toxic elements (PTEs) due to their high inherent toxicity, their persistence in the environment and their tendency to bioaccumulate in sediments and living organisms. We investigated aquatic macrophyte communities and the concentrations of As, Cu, Cd, Cr, Pb, Zn, Ni and Fe in water and sediment samples to identify a pollution pattern along the Sava River and to investigate the potential impact of these PTEs on the diversity and structure of macrophyte communities. The study, which covered 945 km of the Sava River, showed a downstream increase in sediment concentrations of the analyzed elements.
