Exploring Structural Features and Growth Mechanisms in GdBaCuO /LaFeO Bilayers on SrTiO Substrates.

This study investigated a novel approach to enhance the performance of superconductors by applying a LaFeO (LFO) buffer layer on a GdBaCuO (GdBCO) superconducting thin film. LFO is a rare-earth orthoferrite (REFO) materials. The objective was to assess how the thickness of the LFO layer influences the superconducting properties of the GdBCO material.

Enhancement in High-Field Properties and the Flux Pinning Mechanism of ZnO-Buffered MgB Films.

We investigated the flux pinning properties in terms of the critical current density ( ) and pinning force density ( ) of MgB films with ZnO buffer layers of various thicknesses. At higher thicknesses of the buffer layer, significantly larger values are observed in the high-field region, whereas values in the low- and intermediate-field regions remain largely unaffected. A secondary point-pinning mechanism other than primary grain boundary pinning is observed in the analysis, which depends on the thickness of the ZnO buffer layer.

Specific Location of Disc Hemorrhage is Linked to Nerve Fiber Layer Defects.

Purpose: To investigate the relationship between retinal nerve fiber layer (RNFL) defects and the quadrant and proximal location of disc hemorrhages (DHs) in a large population examined for health screening.

Methods: A total of 168,044 subjects older than 20 years underwent a single screening ophthalmic examination with color fundus photography as part of a comprehensive health screening program. The presence and location of DHs and RNFL defects were assessed.

Diurnal intraocular pressure changes in eyes affected with acute primary angle closure and fellow eyes after laser peripheral iridotomy.

Purpose: To evaluate diurnal curves of intraocular pressure (IOP) in eyes affected with unilateral acute primary angle closure (APAC) after laser peripheral iridotomy (LPI), and fellow eyes.

Methods: The medical records of 22 female patients (44 eyes) with unilateral APAC and LPI performed OU were reviewed along with those of 48 normal control subjects (48 eyes). None of the subjects used glaucoma medications after LPI.

In Vivo Assessment of Pharmacologic Vitreolysis in Rabbits With the Digital Fluoroscopy System.

Purpose: The purpose of this study was to demonstrate the efficacy of the digital fluoroscopy system (DFS) for the in vivo assessment of pharmacologically induced posterior vitreous detachment (PVD) and vitreous liquefaction in a rabbit model.

Methods: Twenty eyes from 10 New Zealand white rabbits were divided into 5 groups. In each group, one rabbit received an intravitreal injection of 2.

Disc hemorrhages and their risk factors in an urban South Korean population.

Purpose: The aim of this study was to estimate the prevalence of disc hemorrhage (DH) and evaluate its related risk factors in an urban South Korean population.

Methods: This retrospective cross-sectional study included subjects who underwent health screening at the Health Screening Center of Kangbuk Samsung Hospital from August 2012 to July 2013. All fundus photographs were first reviewed by two ophthalmologists and then by two glaucoma specialists and one retina specialist to determine the presence of DHs.

A patient with branch retinal vein occlusion accompanied by superior ophthalmic vein thrombosis due to severe superior ophthalmic vein enlargement in a patient with graves ophthalmopathy.

We report a patient with branch retinal vein occlusion (BRVO) accompanied by superior ophthalmic vein (SOV) thrombosis resulting from severe SOV enlargement in a patient with Graves ophthalmopathy (GO). A 78-year-old woman diagnosed with BRVO presented with reduced vision. She had a more than 20-year history of unilateral GO.

Single pretreatment of remifentanil may reduce pain after propofol and rocuronium injection in rapid sequence induction.

Background: We designed this double-blind, placebo-controlled study to compare the efficacy of remifentanil in reducing the pain of both propofol and rocuronium injection during rapid-sequence induction.

Methods: Ninety-five patients, scheduled for elective surgery under general anesthesia, were divided into 3 groups: saline (Group S, n = 31), remifentanil 1 µg/kg (Group R, n = 32), and lidocaine 1.5 mg/kg (Group L, n = 32) were administered after tourniquet application.
