Seafloor expression of oceanic detachment faulting reflects gradients in mid-ocean ridge magma supply
2019
International audience; Oceanic detachment faulting is a major mode of seafloor accretion at slow and ultraslow spreading mid-ocean ridges, and is associated with dramatic changes in seafloor morphology. Detachments form expansive dome structures with corrugated surfaces known as oceanic core complexes (OCCs), and often transition to multiple regularly-spaced normal faults that form abyssal hills parallel to the spreading axis. Previous studies have attributed these changes to along-axis gradients in lithospheric strength or magma supply. However, despite the recognition that magma supply can influence fault style and seafloor morphology, the mechanics controlling the transition from oceani…
Detection of Torque Teno Virus (TTV) and TTV-Like Minivirus in patients with presumed infectious endophthalmitis in India
2020
Human anelloviruses (Torque Teno Virus (TTV) and TTV Like Mini Virus (TLMV)) are now being reported at a high prevalence across the world, with a controversial disease-inducing potential. The aim of this study was to investigate the role of these anellovirus in vitreous of patients with presumed infectious endophthalmitis. After informed consent, vitreous fluid from patients with endophthalmitis (n = 103) and non-infectious pathologies (n = 102) were analyzed for the presence of TTV and TLMV DNA by qPCR with the limit of quantification defined as 100 copies per reaction. Among the patients clinically diagnosed with endophthalmitis, 29 of the 40 culture proven samples (72.5%) and 42 out of 6…
Vital dyes in macular hole surgery
2021
Currently, surgical techniques, such as internal limiting membrane peeling, are used widely for macular holes, macular puckers, epiretinal membranes, diabetic macular edema, retinal detachment, retinal vein occlusions, vitreomacular traction, optic pit maculopathy, and Terson syndrome. This study aimed to highlight any differences regarding visual acuity and ocular tomography coherence changes after staining the internal limiting membrane with dilutions of Brilliant Blue G vs. lutein/zeaxanthin-based dyes. This study involved 30 eyes of 30 patients who had undergone posterior pole vitrectomy for idiopathic stage 4 macular hole. The study lot was divided in two subgroups, 15 eyes colored wit…
Modified Vitrectomy Technique for Phakic Rhegmatogenous Retinal Detachment with Intermediate Break
2018
Purpose. To evaluate the effects of a modification of the traditional 25-gauge pars plana vitrectomy technique in the treatment of uncomplicated macula-on rhegmatogenous retinal detachment (RRD) with intermediate retinal break(s) and marked vitreous traction in the phakic eye. Methods. Prospective, noncomparative, and interventional case series. All consecutive phakic eyes with primary uncomplicated macula-on RRD with intermediate retinal break(s) and marked vitreous traction, with at least 1 year of postoperative follow-up, were enrolled. In all eyes, “localized 25-gauge vitrectomy” under air infusion with localized removal of the vitreous surrounding the retinal break(s), in association w…
The Role of Work-Nonwork Boundary Management in Work Stress Recovery
2016
The aim of the present study conducted among 1,106 Finnish employees was to identify boundary management profiles based on cross-role interruption behaviors from work to nonwork and from nonwork to work. Adopting a person-oriented approach through latent profile analysis, 5 profiles were identified: Work Guardians (21% of the employees), Nonwork Guardians (14%), Integrators (25%), Separators (18%), and an Intermediate Group (22%). We then examined differences between these profiles with respect to recovery experiences ( psychological detachment from work, relaxation, mastery experiences, and control during off-job time) and recovery outcomes (vigor and exhaustion). Work Guardians had the po…
Moral Cognition and Multiple Sclerosis: A Neuropsychological Study
2017
Objectives Recent literature proved that social cognition impairments may characterize the neuropsychological profile of Multiple Sclerosis (MS) patients. However, little is still known about moral cognition in MS. In this study, we evaluated non-social, social, and moral cognitive performances in 45 relapsing-remitting MS patients. Methods Patients underwent the Brief International Cognitive Assessment for Multiple Sclerosis battery, the Cognitive Estimation and Stroop tasks, the Ekman-60 Faces test, the Reading the Mind in the Eye and Story-based Empathy task. Additionally, a task of moral dilemmas including both "instrumental" and "incidental" conditions was administered to patients. For…
CORRELATION OF OPTICAL COHERENCE TOMOGRAPHY PATTERN AND VISUAL RECOVERY AFTER VITRECTOMY WITH SILICONE OIL FOR RETINAL DETACHMENT
2006
PURPOSE: To assess prospectively the features of the macular surface in silicone oil-filled eyes after surgery by analyzing whether silicone oil affects optical coherence tomography (OCT) measurements and their reproducibility and whether a statistical correlation exists between postoperative best-corrected visual acuity (BCVA) and foveal thickness measured by OCT. METHODS: Twenty eyes of 20 patients underwent vitrectomy with silicone oil tamponade for retinal detachment. After vitrectomy, complete ophthalmic examination including determination of BCVA and OCT was performed to quantify the visual recovery and the foveal thickness. RESULTS: Ophthalmoscopy revealed that the retina appeared to…
Incidence of posterior vitreous detachment after cataract surgery
2009
Purpose To report the incidence of posterior vitreous detachment (PVD) after uneventful state-of-the-art small-incision phacoemulsification with implantation of a posterior chamber intraocular lens (PC IOL). Setting Department of Ophthalmology, Ludwigshafen Hospital, Ludwigshafen, Germany. Methods This prospective study evaluated the vitreous status of eyes by biomicroscopic examination, indirect binocular ophthalmoscopy, and B-scan ultrasonography before planned cataract surgery. Patients with the posterior vitreous attached were included for follow-up and examined 1 week, 1 month, and 1 year after uneventful phacoemulsification with PC IOL implantation. The preoperative prevalence and pos…
Being mindful at work and at home
2020
Although previous research on mindfulness predominantly focused on benefits of mindfulness, this study investigates quantitative and emotional demands as contextual antecedents of mindful awareness and acceptance both in the work and home domains. In addition, we examine goal attainment and satisfaction in the work and home domains as consequences of mindful awareness and acceptance. Results of a diary study across 5 workdays with 2 daily measurement occasions among 233 employees revealed that both in the work and home domains, quantitative demands were positively associated with awareness, but not with acceptance, whereas emotional demands were positively associated with acceptance, but no…
Long-term results of surgical treatment of high myopia with Worst-Fechner intraocular lenses
1995
Abstract This retrospective study evaluated the results in 90 eyes that had a minus-power anterior chamber intraocular lens implanted to correct high myopia. Preoperative myopia ranged from −7.00 to −24.00 D. Postoperative spherical equivalent was −0.50 D; 80.5% of eyes were within 1.00 D of emmetropia. Two years postoperatively, no cataract formation, retinal detachment, glaucoma, or significant endothelial damage had occurred. We conclude that minus-power lenses can rapidly, safely, and predictably correct high myopia in phakic patients.
