Corneal Biomechanical Parameters With Corneoscleral Contact Lenses in Post-Laser In Situ Keratomileusis Eyes
2018
Objective: To evaluate corneal biomechanical parameters wearing corneoscleral contact lenses (CScL) in patients with irregular corneas after laser in situ keratomileusis (LASIK). Methods: Data from patients fitted with CScL because of corneal surface irregularities after complicated LASIK surgery were selected by two eye clinics. Previously and after 1 year of CScL fitting, corneal hysteresis (CH), corneal resistance factor (CRF), corneal-compensated intraocular pressure (IOPcc), and central corneal thickness were evaluated. In addition, visual acuity, subjective comfort, and wearing time CScL were reported. Results: The study comprised 27 eyes. Statistically significant differences were fo…
Thermal and hygrometric properties of traditional calcarenite stones in the area of Palermo
2017
Il contributo espone le misure di conducibilità termica svolte su tre conci di calcarenite conchiliare e la caratterizzazione igrometrica di uno di essi. I risultati sono confrontati con i dati termici e igrometrici riportati dalle norme tecniche esistenti (UNI 10351, UNI EN ISO 10456, UNI EN 1745). The energy improvement of historic buildings requires detailed knowledge of the thermal and hygrometric properties of traditional materials and components. These data should be collected for specific local contexts, where the features of historic constructions are comparable. For the purpose of developing this tool for the architectural heritage of Palermo, this research focuses on calcarenite s…
Transcriptomes of compatible and non-compatible gray mold/grapevine interactions compared in search of resistance factors
2012
National audience; Gray mold (Botrytis cinerea) causes significant annual yield and quality losses to viticulture. Comparison of transcriptomes of compatible and non-compatible interaction with Vitis vinifera cv Marselan – on harvesting stage berries or véraison stage berries, respectively – suggest the jasmonic acid pathway is activated in the former, while the salicylic acid pathway is more pronounced in the latter. In addition, in the non-compatible case, reactive oxygen species accumulation seems to be both early and strong, and some genes involved in cell-wall reinforcement are up-regulated.
