Evaluate the association between functional recovery and a panel of specific neuronal biomarkers, in a cohort of stroke patients. Serum levels of neuronal specific enolase (NSE), neurofilament light chain (NfL), brain derived neurotrophic factor (BDNF), amyloid-β Linear regression was performed to predict changes in clinical scales during follow up, according to baseline biomarkers levels. NSE at T0 was a significant predictor of improvement in FAC and RMI, where the higher the NSE concentration, the smaller the improvement. Therefore, baseline NSE explained 39% of the variation in FAC and 31% in RMI over time. No significant differences were observed with respect to other scales or other biomarkers. This exploratory study suggested that serum NSE may be a predictor of functional mobility recovery in post-acute stroke patients and represents a useful tool for patients' stratification. Show less

Methylation of CpG islands plays a crucial role in the regulation of gene expression. The study of DNA methylation profiles offers deep insights into key oncogenic processes and facilitates the differentiation of tumor entities at the epigenetic level. Methylation profiling was performed on 8 CNS tumors (6 children, 1 adolescent, 1 young adult) with inconclusive diagnoses, available frozen tissue, and surgeries dating back over 5 years. Our goal was to correlate the resulting methylation classes with the clinical-radiological data and to evaluate the diagnostic and prognostic power of this analysis. The resulting molecularly defined diagnoses were: pilocytic astrocytoma (3 cases), pilocytic astrocytoma subclass Show less
