Chaperonology: The Third Eye on Brain Gliomas
2018
The European Organization for Research and Treatment of Cancer/National Cancer Institute of Canada Phase III trial has validated as a current regimen for high-grade gliomas (HGG) a maximal safe surgical resection followed by radiotherapy with concurrent temozolamide. However, it is essential to balance maximal tumor resection with preservation of the patient&rsquo
Topical glaucoma medications – Clinical implications for the ocular surface
2022
Glaucoma is a leading cause of irreversible blindness. The use of topical eye drops to reduce intraocular pressure remains the mainstay treatment. These eye drops frequently contain preservatives designed to ensure sterility of the compound. A growing number of clinical and experimental studies report the detrimental effects of not only these preservatives but also the active pharmaceutical compounds on the ocular surface, with resultant tear film instability and dry eye disease. Herein, we critically appraise the published literature exploring the effects of preservatives and pharmaceutical compounds on the ocular surface. publishedVersion
Hippocampal theta activity, learning and behavioral tendencies
2014
Trace eyeblink conditioning is a method that models a declarative, awareness-dependent form of learning. Hippocampal theta activity, an approximately 3.5 - 8.5 Hz oscillatory pattern in rabbits, has been associated with learning-related phenomena: arousal, attentional processes and association forming. In some studies theta-contingent training, given during a brain state rich in hippocampal theta oscillation, has improved the initial learning in trace eyeblink conditioning. However, other laboratories have failed to replicate this effect. This study explored the effects of theta-contingent conditioning and extinction on learning, and the connection between the magnitude of spontaneous hippo…

"queste opere eminentemente sinfoniche e spettacolose": Giacomo Meyerbeer’s influence on Italian Opera orchestras
2008
Si prende in esame l'influsso del compositore Giacomo Meyerbeer sull'opera italiana e, in conseguenza, sulle orchestre dei teatri d'opera italiani. La prima parte guarda in generale alla recezione della sua musica in Italia e descrive il suo impatto sul sistema produttivo; la seconda parte discute attraverso specifici esempi l'influenza della sua musica sulla trasformazione delle orchestre dei teatri d'opera durante l'Ottocento. This study analyses Giacomo Meyerbeer's influence on Italian Opera and, consequently, on Italian orchestras. The first part looks at Meyerbeer's reception in Italy and describes his impact on the system of opera production there; the second part discusses the subseq…
Effect of even and odd-order aberrations on the accommodation response
2017
Aim To investigate the potential effect that odd and even-order monochromatic aberrations may have on the accommodation response of the human eye. Methods Eight healthy subjects with astigmatism below 1 D, best corrected visual acuity 20/20 or better and normal findings in an ophthalmic examination were enrolled. An adaptive optics system was used in order to measure the accommodation response of the subjects' eyes under different conditions: with the natural aberrations being present, and with the odd and even-order aberrations being corrected. Three measurements of accommodation response were monocularly acquired at accommodation demands ranging from 0 to 4 D (0.5 D step). Results The acc…

Hot towels
2023
Background Meibomian gland dysfunction (MGD) reduces quality-of-life and hinders work productivity of millions of patients, with high direct and indirect societal costs. Thickened meibum obstructs the glands and disrupts ocular surface health. Heating the eyelids to soften and express meibum from the glands can be beneficial. The most accessible method for eyelid warming uses heated, wet towels. However, the efficacy of this treatment is reliant on the methodology, and evidence-based best-practice recommendations are needed. Purpose To evaluate the literature on hot towels in MGD treatment and recommend a best-practice protocol for future research and patient treatment. Methods Studies were…
