The influence of environmental factors on sleep quality in hospitalized medical patients.

Turco M, Corrias M, Chiaromanni F, Bano M, Salamanca M, Caccin L, Merkel C, Amodio P, Romualdi C, De Pittà C, Costa R, Montagnese S. Chronobiology International The assessment of diurnal preference, or the preferred timing of sleep and activity, is generally based on comprehensive questionnaires such as the Horne-Östberg (HÖ). The aim of the […]

The influence of environmental factors on sleep quality in hospitalized medical patients

Bano M, Chiaromanni F, Corrias M, Turco M, De Rui , Amodio P, Merkel C, Gatta A, Mazzotta G, Costa R, Montagnese S. Frontiers in Neurology INTRODUCTION: Sleep-wake disturbances are common in hospitalized patients but few studies have assessed them systematically. The aim of the present study was to assess sleep quality in a group […]

Fly cryptochrome and the visual system.

Mazzotta G, Rossi A, Leonardi E, Mason M, Bertolucci C, Caccin L, Spolaore B, Martin AJ, Schlichting M, Grebler R, Helfrich-Förster C, Mammi S, Costa R, Tosatto SC. Proceeding of the National Academy of Sciences Abstract Cryptochromes are flavoproteins, structurally and evolutionarily related to photolyases, that are involved in the development, magnetoreception, and temporal organization […]

Drosophila clock neurons under natural conditions.

Menegazzi P, Vanin S, Yoshii T, Rieger D, Hermann C, Dusik V, Kyriacou CP, Helfrich-Förster C, Costa R. Journal of biological rhythms Abstract The circadian clock modulates the adaptive daily patterns of physiology and behavior and adjusts these rhythms to seasonal changes. Recent studies of seasonal locomotor activity patterns of wild-type and clock mutant fruit […]

Unexpected features of Drosophila circadian behavioural rhythms under natural conditions.

Vanin S, Bhutani S, Montelli S, Menegazzi P, Green EW, Pegoraro M, Sandrelli F, Costa R, Kyriacou CP. Nature Abstract Circadian clocks have evolved to synchronize physiology, metabolism and behaviour to the 24-h geophysical cycles of the Earth. Drosophila melanogaster’s rhythmic locomotor behaviour provides the main phenotype for the identification of higher eukaryotic clock genes. […]
