Late post‐natal neurometabolic development in healthy male rats using 1 H and 31 P Magnetic Resonance Spectroscopy

Rolf Gruetter, Cristina Ramona Cudalbu, Dunja Simicic, Veronika Rackayová, Guillaume Donati

Brain metabolism evolves rapidly during early post‐natal development in the rat. While changes in amino acids, energy metabolites, antioxidants or metabolites involved in phospholipid metabolism have been reported in the early stages, neurometabolic change ...

C-reactive protein and white matter microstructural changes in COVID-19 patients with encephalopathy

Alessandra Griffa

Encephalopathy is a neurological complication of COVID-19. The objective of this exploratory study is to investigate the link between systemic inflammation and brain microstructural changes (measured by diffusion-weighted imaging) in patients with COVID-19 ...

Type 2 diabetes (T2D) is associated with deterioration of brain structure and function. Here, we tested the hypothesis that T2D induces a reorganization of the brain metabolic networks that support brain function. For that, alterations of neuronal and glia ...

Longitudinal neurometabolic changes in the hippocampus of a rat model of chronic hepatic encephalopathy

Cristina Ramona Cudalbu, Jocelin Grosse, Katarzyna Pierzchala, Veronika Rackayová

Background & Aims: The sequence of events in hepatic encephalopathy (HE) remains unclear. Using the advantages of in vivo 1H-MRS (9.4T) we aimed to analyse the time-course of disease in an established model of type C HE by analysing the longitudinal change ...
