Determinants of Generative AI System Adoption and Usage Behavior in Korean Companies: Applying the UTAUT Model.

This study addresses the academic gap in the adoption of generative AI systems by investigating the factors influencing technology acceptance and usage behavior in Korean firms. Although recent advancements in AI are accelerating digital transformation and innovation, empirical research on the adoption of these systems remains scarce. To fill this gap, this study applies the Unified Theory of Acceptance and Use of Technology (UTAUT) model, surveying 300 employees from both large and small enterprises in South Korea.

Visual performance and impact of residual refractive errors with trifocal intraocular lenses of different aspheric design.

Background: To assess the visual quality and the tolerance to low refractive errors of two trifocal intraocular lenses (IOL) with different amounts of spherical aberration (SA).

Methods: The study included patients having bilateral implantation of the AcrySof® IQ PanOptix (aberration-correcting) or the RayOne (aberration-free) Trifocal IOL. Three months after the surgery patients underwent: monocular/binocular and uncorrected/corrected distance visual acuity (VA) and binocular defocus curves.

Effect of residual astigmatism and defocus in eyes with trifocal intraocular lenses.

Purpose: To assess the effect on visual function of different residual astigmatic situations combined with 0.50 diopters (D) negative defocus at different distances in patients with trifocal intraocular lenses (IOLs).

Setting: Clínica Rementería, Madrid, Spain.

Impact of Trifocal and Trifocal Toric Intraocular Lenses on Spectral-domain OCT Retinal Measurements.

Precis: Monofocal, trifocal, and trifocal toric intraocular lenses (IOLs) induce similar changes on overall retinal optical coherence tomography (OCT) measurements.

Purpose: The purpose of this study was to assess whether trifocal and trifocal toric IOLs affect the measurement of retinal parameters using spectral-domain OCT.

Methods: This cross-over study included patients undergoing implantation of a trifocal IOL: AcrySof IQ PanOptix, a trifocal toric IOL: AcrySof IQ PanOptix Toric, and a monofocal IOL: AcrySof IQ.

Anesthesia Protocols used to Create Ischemia Reperfusion Myocardial Infarcts in Swine.

The porcine ischemia-reperfusion model is one of the most commonly used for cardiology research and for testing interventions for myocardial regeneration. In creating ischemic reperfusion injury, the anesthetic protocol is important for assuring hemodynamic stability of the animal during the induction of the experimental lesion and may affect its postoperative survival. This paper reviews the many drugs and anesthetic protocols used in recent studies involving porcine models of ischemiareperfusion injury.

Efficacy and safety of a soft contact lens to control myopia progression.

Clinical Relevance: The control of myopia progression is currently considered an evidence-based therapeutic need.

Background: To determine the efficacy and safety of the Esencia lens, a new soft contact lens (SCL) designed to slow down myopia progression in paediatric patients.

Methods: This study was a randomised, parallel, double-masked clinical trial.

Automated refraction after trifocal and trifocal toric intraocular lens implantation.

Background: To analyze the correlation between automated refraction and manifest refraction after implantation of a trifocal intraocular lens or its toric version.

Methods: This cross-sectional study involved 105 eyes of 105 patients. Subjects were divided in two groups: 62 with trifocal (AcrySof PanOptix) and 43 with trifocal toric (AcrySof PanOptix Toric) intraocular lenses.

Visual quality and patient satisfaction with a trifocal intraocular lens and its new toric version.

Purpose: To assess and compare the visual quality and subjective outcomes of a trifocal spherical intraocular lens (IOL) and its new toric version.

Setting: Clínica Rementería, Madrid, Spain.

Design: Prospective case series.

Factors related to limitation of life support within 48h of intensive care unit admission: A multicenter study.

Objective: To determine factors related to limitations on life support within 48h of intensive care unit (ICU) admission.

Study Design: Prospective multicenter study.

Setting: Eleven ICUs.

Clinical outcomes after Ex-PRESS glaucoma shunt versus non-penetrating deep sclerectomy: two-year follow-up.

Purpose: To compare the two-year outcomes of non-penetrating deep sclerectomy (NPDS) and Ex-PRESS glaucoma shunt.

Methods: A retrospective chart review of patients who had undergone NPDS or Ex-PRESS since 2012 was conducted. Patients were excluded if they had undergone eye surgery other than cataract extraction, were diagnosed with ocular pathology other than glaucoma or had less than two-year follow-up.

Short term visual outcomes of a new trifocal intraocular lens.

Background: Today, patients often expect to achieve spectacle independance after cataract surgery. New trifocal intraocular lenses have been developed to try and fullfill this demand. The purpose of this study is to report the short-term visual outcomes of a new trifocal intraocular lens (AcrySof PanOptix™).

Association of lifestyle, inflammatory factors, and dietary patterns with the risk of suffering a stroke: A case-control study.

Background: Lifestyle, including dietary patterns, could involve specific factors participating in inflammation that confer a higher risk of suffering a stroke. However, little attention has been apparently given to habitual food consumption in patients suffering a cerebrovascular event.

Objective: To assess the influence of dietary habits as well as other lifestyle-related variables on the risk of suffering a stroke.

Epigenetic Changes in the Methylation Patterns of KCNQ1 and WT1 after a Weight Loss Intervention Program in Obese Stroke Patients.

Ischemic stroke patients often show high concentrations of circulating inflammatory markers that are associated with increased risk of recurrence. Epigenetic mechanisms could be involved in obesity, inflammation and stroke. The objective of this research was to investigate, in obese patients suffering a previous stroke, the effects of a nutritional program on anthropometric and biochemical variables, and on the methylation patterns of two stroke-related genes (KCNQ1: potassium channel, voltage gated KQT-like subfamily Q, member 1; and WT1: Wilms tumor 1).

Obesity and ischemic stroke modulate the methylation levels of KCNQ1 in white blood cells.

Obesity and stroke are multifactorial diseases in which genetic, epigenetic and lifestyle factors are involved. The research aims were, first, the description of genes with differential epigenetic regulation obtained by an 'omics' approach in patients with ischemic stroke and, second, to determine the importance of some regions of these selected genes in biological processes depending on the body mass index. A case-control study using two populations was designed.

The CD26 antigen is coupled to protein tyrosine phosphorylation and implicated in CD16-mediated lysis in natural killer cells.

The levels of CD26 expression, their capacity to induce protein tyrosine phosphorylation and their functional implication in natural killer (NK) cytolysis have been studied. It was found that only a small fraction (12-15%) of peripheral NK cells expresses CD26 compared with the high expression (99%) found in NK clones. The protein tyrosine phosphorylation mediated by means of CD26 activation was studied in NK cells treated with the anti-CD26 MoAb 134-2C2, and two new proteins of 50 and 21 kDa appeared phosphorylated in tyrosine residues.
