Is skeletal muscle enriched in hematopoietic stem cells and not inflammatory cells in cachectic mice?
The elevated levels of cytokines which characterize cachexia may represent a trigger for inflammatory cell activation. However, we find that in cachexia, inflammatory cells in muscle are not increased while muscle tissue nuclei decline. Our data suggest that the inflammatory cell-mediated stress is not an etiologic component of muscle wasting in cachexia. The relative increase in HSCs in cachectic skeletal muscle suggests an attempt to maintain muscle homeostasis by recruitment and/or activation of stem cells.
EEG analysis, based on continues wavelet transform, provides quantifiable information on static as well as dynamic features of the EEG in patients with HE. EEG abnormalities were correlated to psychometric test performance and may provide valuable clinical biomarkers for surveillance, prognostication and treatment of this entity.
