Activation of the kynurenine pathway identified in individuals with covert hepatic encephalopathy

Zeng G, Krishnamurthy S, Staats Pires A, Guller A, Chaganti J, Tun N, Lockart I, Montagnese S, Brew B, Guillemin GJ, Danta M, Heng B Hepatol Commun Background: HE is a neuropsychiatric complication of liver disease characterized by systemic elevation in ammonia and proinflammatory cytokines. These neurotoxins cross the blood-brain barrier and cause neuroinflammation, which can […]

Sleep timing in flies from “adolescence” to adulthood

Domenie ED, Cusumano P, Montagnese S, Costa R Fly (Austin) The aim of the present study was to assess sleep timing in Drosophila melanogaster at different ages, within the setting of an enforced schedule of varying light-dark stimuli, simulating light exposure variations between four typical office working days and one free day spent outside by a human, for a total of […]

Assessing evidence in translational chronobiology: The cases of Daylight Saving Time and road safety, and of school start times and sleep duration

Giusti G, Mangini C, Erminelli D, Domenie ED, Montagnese S Chronobiology International One of the main challenges in translating chronobiology research into clinical practice is represented by differences in how basic scientists and clinicians evaluate evidence. The workshop “Assessing Evidence in Translational Chronobiology,” which was held at the University of Surrey in June 2023, addressed […]

Electrophysiological and hemodynamic mechanisms underlying load modulations in visuospatial working memory: A functional near-infrared spectroscopy (fNIRS) and electroencephalogram (EEG) study

Zarantonello L, Brigadoi S, Schiff S, Bisiacchi PS, Cutini S, Montagnese S, Amodio P Behav Neurosci The n-back task has been widely used to study working memory. Previous studies investigating the electrophysiological (electroencephalogram [EEG]) and hemodynamic correlates (functional near-infrared spectroscopy [fNIRS]) of the n-back task have been generally based on verbal stimuli and only investigated […]

Long-term effects of daylight saving time on driving fatigue

Orsini F, Domenie ED, Zarantonello L, Costa R, Montagnese S, Rossi R Heliyon The study of the relationship between Daylight Saving Time (DST) and road safety has yielded contrasting results, most likely in relation to the inability of crash-database approaches to unravel positive (ambient lighting-related) and negative (circadian/sleep-related) effects, and to significant geographical differences in […]
