Internal limiting membrane peeling versus no peeling during primary vitrectomy for rhegmatogenous retinal detachment: A systematic review and meta-an…

2018

Background Internal limiting membrane (ILM) peeling during primary vitrectomy for rhegmatogenous retinal detachment (RRD) prevents the formation of postoperative macular epiretinal membrane (ERM). However, studies that compared vitrectomy with and without ILM peeling for RRD, have reported controversial outcomes. Objective To assess the efficacy of ILM peeling versus non-ILM peeling during vitrectomy for RRD by a systematic review and meta-analysis of published studies. Methods PubMed, Medline, Web of Science, Embase databases, and the Cochrane Library were searched up to April 2018 to identify studies that compared primary vitrectomy with and without ILM peeling for RRD with at least six m…

Laboratory phase‐contrast nanotomography of unstained Bombus terrestris compound eyes

2021

Imaging the visual systems of bumblebees and other pollinating insects may increase understanding of their dependence on specific habitats and how they will be affected by climate change. Current high-resolution imaging methods are either limited to two dimensions (light- and electron microscopy) or have limited access (synchrotron radiation x-ray tomography). For x-ray imaging, heavy metal stains are often used to increase contrast. Here, we present micron-resolution imaging of compound eyes of buff-tailed bumblebees (Bombus terrestris) using a table-top x-ray nanotomography (nano-CT) system. By propagation-based phase-contrast imaging, the use of stains was avoided and the microanatomy co…

Influence of different approaches to the cerebellopontine angle on the function of the intermediate nerve

2007

Object Surgery in the cerebellopontine angle (CPA) is a standard procedure at many centers. Outcome is focused mainly on preservation of hearing and facial function postoperatively. The nonmotor part of the facial nerve, the intermediate nerve, is nearly neglected nowadays. Methods A retrospective study was designed, including a questionnaire that was sent to 178 patients who had undergone surgery between 2000 and 2004. Data were obtained in 156 cases. The questionnaire was divided into five parts assessing the presence of increased tearing, reduced tearing, salivation disturbances, increased nasal secretions, and abnormalities in taste. Finally, a self-assessment of patient symptoms was a…

Application of action camera video for fast and low-cost photogrammetric survey of cultural heritage

2022

Abstract. The research work focuses on the growing of fast and low-cost data surveying methods (both in the acquisition and processing phases), to be used mainly as a support for the management and enhancement of architectural heritage. Attention is paid on the diffusion of action cameras, characterized by wide-angle lenses and 4K video shooting, with more and more affordable prices and on the elaboration of the data with photogrammetry software. The high-resolution videos captured by these tools, in fact, allow the selection of frames characterized by sufficient overlap, necessary for point cloud generation through Structure for Motion (SfM) processes. The focus is on indoor environment ch…

Tonographic Effect of Ocular Response Analyzer in Comparison to Goldmann Applanation Tonometry.

2016

AIMS The tonographic effect is a phenomenon of intraocular pressure (IOP) reduction following repeated tonometry. This study examines whether the tonographic effect occurs following IOP measurement performed with Ocular Response Analyzer (ORA). METHODS Both eyes of 31 glaucoma patients and 35 healthy controls underwent nine IOP-measurements performed with GAT and ORA. The number of GAT and ORA measurements performed on each eye differed depending on the randomly allocated investigation scheme. Central corneal thickness (CCT), anterior chamber volume (ACV) and anterior chamber depth (ACD) were assessed with Pentacam before and after the repeated GAT/ORA measurements. RESULTS There was no sta…

Rebecca abused: a comparative analysis of censorship in the novel and its film adaptation

2019

En 1938, la escritora inglesa Daphne du Maurier (1907-1989) completaba la escritura de Rebecca. En 1940, se estrenaba la adaptación cinematográfica, dirigida por Alfred Hitchcock. La escasa estima que sentía Hitchcock por la novela original, así como los fundamentos del puritano Código Hays (1930), hicieron que el guion original tuviera que ser enmendado. Paralelamente, en 1938, se imponía en España la Ley de Prensa, que pondría al servicio del régimen franquista toda la producción literaria. Sin embargo, la censura franquista dio carta blanca a Rebeca (novela y adaptación cinematográfica). En este trabajo analizamos los comportamientos censores de ambos códigos, coetáneos y similares en cu…
