Applications of a biocompatible alginate/pericardial fluid-based hydrogel for the production of a bioink in tissue engineering.

Enhancing the biocompatibility of biomaterials is a critical aspect of tissue engineering and regenerative medicine. Advances in 3D bioprinting technology, blending natural and synthetic materials for the production of bioink, offer new opportunities to develop highly biocompatible materials that can closely mimic the native tissue environment. In this study, we used pericardial fluid structure (PFS)-based material together with alginate to mimic the extracellular matrix (ECM) and produce a bioink material.

Evaluation and comparison of optical coherence tomography angiography (OCTA) parameters in normal and moderate myopic individuals.

Objective: The objective of this study was to evaluate and compare Optical Coherence Tomography Angiography (OCTA) parameters in patients with moderate myopia and healthy individuals retrospectively.

Methods: A total of 80 male individuals aged 18-20 years were included in the study with 40 moderate myopic and 40 healthy persons. All participants underwent detailed ocular examination including refraction, intraocular pressure (IOP), visual acuity, biomicroscopy, OCTA measurement and optic biometry measurement.

The relationship between Choroidal Vascular Index and non-invasive ultrasonographic atherosclerosis predictors.

Background: This study explores the intricate connections between choroidal vascular index (CVI) and non-invasive ultrasonographic atherosclerosis predictors, shedding light on the potential links between ocular vascular dynamics and systemic cardiovascular health.

Methods: We conducted a cross-sectional analysis of 81 participants, assessing CVI, intima-media thickness (IMT), extra-media thickness (EMT), and the PATIMA index. The presence of coronary artery disease (CAD) was also evaluated.

Preoperative Evaluation of White Cataracts with the Pentacam.

Purpose: To evaluate the use of the Pentacam to analyse the presence or absence of fluid pockets under the anterior capsule and their significance in terms of surgical management and prevention of complications.

Settings: Abant İzzet Baysal University Hospital, Bolu, Turkey DESIGN: Randomized, masked, prospective design METHODS: 60 patients with mature cataracts underwent standard phacoemulsification (Phaco) and intraocular lens (IOL) implantation. Patients were divided into 3 groups.

Comparison of the Short-Term Effect of Coffee, Energy Drink, and Water on the Eyes in Young Healthy Subjects.

Purpose: We aim to compare the short-term effects of energy drink (ED), coffee, and water on the eyes of young healthy male subjects.

Materials And Methods: The right eyes of 30 healthy male subjects were included in this study. We measured the intraocular pressure (IOP), mean arterial pressure (MAP), retinal thickness (RT), choroidal thickness (CT), and retinal nerve fiber layer (RNFL) thickness using spectral domain optical coherence tomography (SD OCT).
