“…Methods: A retrospective cross-sectional study involving eyes with MHs which underwent 23- or 25-gauge PPV with or without phacoemulsification and all undergoing a 20% SF6 gas tamponade, follow-up to 6 months postoperatively were included at the Department of Ophthalmology, Oslo University Hospital and University of Oslo, Oslo, Norway (12-month study period between 1 January and 31 December 2015) Pre- and post-operative Best-Corrected Visual Acuity (BCVA) assessment, comprehensive eye examination and intraocular pressure (IOP) measurement. as well as Optical Coherence Tomography to determine the diameter of the MH and its closure were all carried out. …”

“…The (13)C SSNMR, FTIR, and Raman data showed the presence of organic species derived from the 1-hexanol reactant remaining within the samples. The optical absorption, studied using UV–visible spectroscopy, indicated that the band gap (E(g)) shifted systematically to lower energy with decreasing NP sizes. …”

“…Therefore, searching for strategies to simultaneously unify the sizes of colloids and inhibit particle growth has become significantly important for LAL-synthesized nanomaterials to be extensively used for biological, catalytic, and optical applications, in which fields particle size plays an important role. …”

“…This would be important for manufacturing materials with properties (for instance, the optical property) independent of temperature. From the current study, the binary blends of the antisymmetric diblock copolymers are concluded to be versatile such that the precise controls of the morphologies and the temperature dependencies of the lamellar microdomains are plausible.…”

“…METHODS: An observational cross-sectional study was conducted of 104 eyes, which were divided into 4 groups: Healthy controls (n = 38), DM with no DR eyes (n = 22), panretinal photocoagulation-untreated non-proliferative DR eyes (PRP-untreated NPDR eyes) (n = 24), PRP-untreated proliferative DR eyes (PRP-untreated PDR eyes) (n = 20). Optical coherence tomography (OCT) was performed. …”

“…An ideal microscope for 3-D tissue imaging at these different scales would combine features from both confocal laser-scanning and light-sheet microscopes: a micrometric optical sectioning capacity and sub-micrometric spatial resolution, a large field of view and high frame rate, and a low degree of invasiveness, i.e., ideally, a better photon efficiency than that of a confocal microscope. …”
