BACKGROUND To date there are no biomarkers with proven reliability as a measure of disease burden in amyotrophic lateral sclerosis (ALS). The aim of our study is to assess the neurofilament light chain (NFL) in cerebrospinal fluid (CSF) samples as a measure of disease activity and progression in ALS. METHODS Thirty-seven consecutive patients with ALS, 25(More)
BACKGROUND The identification of biomarkers able to improve the differential diagnosis between multiple sclerosis (MS) and neuromyelitis optica (NMO) is challenging because of a different prognosis and response to treatment. Growing evidence indicates that brain and CSF N-acetyl aspartate (NAA) concentration is a useful marker for characterising different(More)
A monolithic multi-terminal logic device that functions both optically and electrically as an "ORNAND" gate, is demonstrated for the first time. The device, based on the real-space transfer of hot electrons into a complementary collector layer, has been implemented in MBE-grown InGaAsflnAlAs heterostructure. Excellent performance is obtained at room(More)
BACKGROUND N -acetylaspartate (NAA) level is a biomarker of functional integrity and vitality in neurons. In vivo multisection proton ((1)H)-magnetic resonance spectroscopy studies indicate that NAA level decreases in specific cortical brain areas of patients with amyotrophic lateral sclerosis (ALS). OBJECTIVE To study NAA level in serum samples as a(More)
BACKGROUND AND PURPOSE To evaluate whether cerebrospinal fluid (CSF) neurofilament light chain (NFL) levels could predict the time to generalization (TTG) in amyotrophic lateral sclerosis (ALS). METHODS Cerebrospinal fluid NFL levels of 37 cases of sporadic ALS were measured and the time of symptom spreading from spinal or bulbar localization to both(More)
The aim of our project was to perform an exploratory analysis of the cerebrospinal fluid (CSF) proteomic profiles of Multiple Sclerosis (MS) patients, collected in different phases of their clinical course, in order to investigate the existence of peculiar profiles characterizing the different MS phenotypes. The study was carried out on 24 Clinically(More)
BACKGROUND Identifying markers of cognitive dysfunction in multiple sclerosis (MS) is extremely challenging since it means supplying potential biomarkers for neuroprotective therapeutic strategies. OBJECTIVE The aim of this study is to investigate the relationship between fMRI correlates of attention performance and cerebrospinal fluid (CSF) neurofilament(More)
OBJECTIVE To investigate the effect of two-years Natalizumab treatment on plasma Osteopontin levels, cognitive performances and fatigue in relapsing multiple sclerosis (RRMS) patients. METHODS Forty-nine RRMS patients scheduled for Natalizumab treatment as second-line therapy were enrolled. Plasma samples of twenty-four treatment-naïve RRMS and 22 healthy(More)
Previously we demonstrated a new class of VLSI-compatible multiemitter Si/SiGe/Si npn HBTs with enhanced logic functionality. These devices have two (or more) emitter contacts and no base contact. Given a potential difference between any two emitter contacts, one of the emitter-base junctions is forward biased and injects electrons into the base, while the(More)
