Short-Term Changes in Light Distortion in Orthokeratology Subjects

2015

Purpose. Quantifying adaptation to light distortion of subjects undergoing orthokeratology (OK) for myopia during the first month of treatment. Methods. Twenty-nine healthy volunteers (age: 22.34 ± 8.08 years) with mean spherical equivalent refractive error −2.10 ± 0.93D were evaluated at baseline and days 1, 7, 15, and 30 of OK treatment. Light distortion was determined using an experimental prototype. Corneal aberrations were derived from corneal topography for different pupil sizes. Contrast sensitivity function (CSF) was analyzed for frequencies of 1.50, 2.12, 3.00, 4.24, 6.00, 8.49, 12.00, 16.97, and 24.00 cpd under photopic conditions. Results. Average monocular values of all light di…

Trifocal toric intraocular lenses in eyes with low amount of corneal astigmatism.

2020

Aim To evaluate the refractive and visual outcomes following cataract surgery and implantation of a trifocal toric intraocular lens (IOL) in eyes with low degrees of corneal astigmatism. Methods Twenty-six eyes of 22 patients who underwent implantation a trifocal toric IOL (FineVision PODFT, PhysIOL s.a., Liege, Belgium) were enrolled. Phacoemulsification with femtosecond laser, capsular tension ring insertion and intraoperative aberrometry were performed in all cases. All IOLs used showed a cylinder power of 1.00 D. Main outcome measures were refractive error and corrected-distance visual acuity (CDVA) and uncorrected-distance visual acuity (UDVA) values. Eyes were evaluated at 4mo post-su…

Keratoconus apex positions impact on visual acuity and contrast sensitivity

2020

The change of corneal shape in keratoconus subjects can impact the optical quality of the eye on the retina and it reduces the contrast sensitivity by light scattering. The aim of our study was to estimate the keratoconus subjects’ contrast sensitivity and visual acuity depending on keratoconus apex position. We included 45 keratoconus subjects (77 eyes), which have keratoconus in the first to the third stage, in our study. There were 33 eyes with keratoconus apex in the central part of the cornea and 46 eyes with keratoconus apex in the periphery of the cornea. Contrast sensitivity and visual acuity were measured at 3 m with and without the best possible spectacle correction using the FrAC…

IFN-gamma-induced protein 10 is a novel biomarker of rhinovirus-induced asthma exacerbations

2007

BACKGROUND: Rhinovirus-induced acute asthma is the most frequent trigger for asthma exacerbations. OBJECTIVE: We assessed which inflammatory mediators were released from bronchial epithelial cells (BECs) after infection with rhinovirus and then determined whether they were also present in subjects with acute virus-induced asthma, with the aim to identify a biomarker or biomarkers for acute virus-induced asthma. METHODS: BECs were obtained from bronchial brushings of steroid-naive asthmatic subjects and healthy nonatopic control subjects. Cells were infected with rhinovirus 16. Inflammatory mediators were measured by means of flow cytometry with a cytometric bead array. Subjects with acute a…

Root-induced decomposer growth and plant N uptake are not positively associated among a set of grassland plants

2007

Abstract It is known that plant species can induce development of different soil decomposer communities and that they differ in their influence on organic matter decomposition and N mineralization in soil. However, no study has so far assessed whether these two observations are related to each other. Based on the hypothesis that root-induced growth of soil decomposers leads to accelerated decomposition of SOM and increased plant N availability in soil, we predicted that (1) among a set of grassland plants the abundance of soil decomposers in the plant rhizosphere is positively associated with plant N uptake from soil organic matter. To test this, we established grassland microcosms consisti…

SISTEMI DI CORONAMENTO E SMALTIMENTO DELLE ACQUE METEORICHE : LA REGOLA DELL'ARTE DAI TRATTATI AI MANUALI

2018

Il saggio approfondisce gli aspetti storici e costruttivi dei cornicioni che, da elementi di protezione, possono divenire, a causa della propria forma, talvolta anche elementi di degrado e dissesto. La struttura del testo del presente volume si compone di tre parti principali, presentando alcuni aspetti tecnici e questioni di non comune attenzione. La prima parte analizza una disamina sui valori formali e materiali del cornicione; esso presenta, infatti, caratteri complessi e riassume, proprio per la doppia valenza di ornamento (coronamento dell’edificio) e componente funzionale (sistema di allontanamento delle acque meteoriche dalla facciata) le problematiche che derivano da esigenze forma…

Molecular markers indicate the phylogenetic identity of southern Brazilian sea asparagus: first record of Salicornia neei in Brazil

2019

Abstract Molecular phylogenetic analyses based on ETS, ITS and atpB - rbcL spacer sequences assessed the phylogenetic status of the southern Brazil sea asparagus species of the genus Salicornia (Salicornioideae, Amaranthaceae). Accessions of Patos Lagoon estuary (32° S) were obtained from wild plants and two pure line lineages, selected from contrasting prostrate (BTH1) and decumbent (BTH2) ecomorphotypes found locally. Patos Lagoon wild plants, BTH1 and BTH2 f4 progenies showed 100% identical sequences for the atpB - rbcL and ITS spacers, only two mutations for ETS. Comparison of the sequences of these three markers with GenBank records confirmed the identity of Brazilian accessions as Sal…

(±)-alternarlactones A and B, two antiparasitic alternariol-like dimers from the fungus alternaria alternata P1210 isolated from the halophyte salico…

2019

Two new dimeric compounds of the alternariol class, (±)-alternarlactones A (1) and B (2), were isolated along with 11 known compounds from the fungus Alternaria alternata P1210. Their structures were elucidated with the assistance of long-range HSQMBC to address inadequate cross-peaks in HMBC that result from the highly dense quaternary carbons, as well as theoretical calculations. All isolated altenuisol derivatives were screened for their antiparasitic activities, which provide a preliminary structure-activity relationship of this class of compounds against neglected tropical diseases.

Conjunctival Sac Fluid Contains Elevated Levels of Soluble TRAIL: Implications for the Anti-Tumoral Surveillance of the Anterior Surface of the Eye

2008

Little is known on the ability of different epithelia to release soluble TNF-related apoptosis-inducing ligand (TRAIL) and the relevance of TRAIL secretion by epithelial cells is still incompletely understood. On these bases, we have measured the concentration of soluble TRAIL by ELISA in the conjunctival sac fluid. It was the highest ever detected in a biological fluid (mean value of 26,800 pg/ml), being approximately 20-fold greater than that found in human saliva and >200-fold greater than that detected in human serum. On the other hand, osteoprotegerin, the soluble decoy receptor of TRAIL, was almost undetectable in the conjunctival sac fluid. Of note, the levels of soluble TRAIL measur…
