A targeted RNA interference screen for […]

Sleep, Circadian Rhythmicity and Response to Chronotherapy in University Students: Tips from Chronobiology Practicals

Montagnese S, Zarantonello L, Formentin C, Zancato C, Bonetto M B, Biscontin A, Cusumano P, Costa R (2021) Journal of Circadian Rhythms Chronobiology is not routinely taught to biology or medical students in most European countries. Here we present the results of the chronobiology practicals of a group of students of the University of Padova, with a […]

Gufi o allodole? Cosa sono e come funzionano gli orologi circadiani.

Costa R, Montagnese S L’orologio circadiano, che regola i ritmi sonno-veglia e altri aspetti della nostra fisiologia, si sincronizza con l’ambiente naturale che ci circonda, soprattutto per mezzo della luce del Sole. Tuttavia le nostre abitudini di vita, condizionate dall’orologio sociale, spesso confliggono con i ritmi dettati dall’orologio circadiano. Questo favorisce l’insorgenza di malattie, anche […]

The µMCTQ: An Ultra-Short Version of the Munich ChronoType Questionnaire.

Ghotbi N, Pilz LK, Winnebeck EC, Vetter C, Zerbini G, Lenssen D, Frighetto G, Salamanca M, Costa R, Montagnese S, Roenneberg T Journal of Biological Rhythms Individuals vary in how their circadian system synchronizes with the cyclic environment (zeitgeber). Assessing these differences in “phase of entrainment”-often referred to as chronotype-is an important procedure in laboratory […]

Predictive value of induced hyperammonaemia and neuropsychiatric profiling in relation to the occurrence of post-TIPS hepatic encephalopathy

Senzolo M, Zarantonello L, Formentin C, Orlando C, Beltrame F, Vuerich A, Angeli P, Burra P, Montagnese S Metabolic Brain Disease Hepatic encephalopathy (HE) occurs in 20–50% of patients after transjugular intrahepatic portosystemic shunt (TIPS) placement. Older age, HE history and severe liver failure have all been associated with post-TIPS HE but it remains difficult to […]

Knockdown of APOPT1/COA8 Causes Cytochrome c Oxidase Deficiency, Neuromuscular Impairment, and Reduced Resistance to Oxidative Stress in Drosophila melanogaster

Brischigliaro M, Corrà S, Tregnago C, Fernandez-Vizarra E, Zeviani M, Costa R, De Pittà C Frontiers in Physiology Cytochrome c oxidase (COX) deficiency is the biochemical hallmark of several mitochondrial disorders, including subjects affected by mutations in apoptogenic-1 (APOPT1), recently renamed as COA8 (HGNC:20492). Loss-of-function mutations are responsible for a specific infantile or childhood-onset mitochondrial leukoencephalopathy with a chronic clinical course. […]

Peptidergic signaling from clock neurons regulates reproductive dormancy in Drosophila melanogaster.

Nagy D, Cusumano P, Andreatta G, Anduaga AM, Hermann-Luibl C, Reinhard N, Gesto J, Wegener C, Mazzotta G, Rosato E, Kyriacou CP, Helfrich-Förster C, Costa R. PLoS Genetics With the approach of winter, many insects switch to an alternative protective developmental program called diapause. Drosophila melanogaster females overwinter as adults by inducing a reproductive arrest that is […]

The RNA helicase BELLE is involved in circadian rhythmicity and in transposons regulation in Drosophila melanogaster

Paola Cusumano, Milena Damulewicz, Elena Carbognin, Laura Caccin, Antonietta Puricella, Valeria Specchia, Maria Pia Bozzetti, Rodolfo Costa, Gabriella M. Mazzotta Frontiers in Physiology Circadian clocks control and synchronize biological rhythms of several behavioral and physiological phenomena in most, if not all, organisms. Rhythm generation relies on molecular auto-regulatory oscillations of interlocked transcriptional-translational feedback loops. Rhythmic clock-gene […]
