Combining the photo-Fenton catalytic reaction with membrane separation technology can effectively treat oils and dyes in water. However, single iron-based catalysts suffer from limited photogenerated carrier utilization and slow Fe/Fe redox reactions, leading to membrane contamination. In this study, iron oxyhydroxide and Prussian blue were grown on a PVDF membrane, optimizing electron transfer to improve the catalytic efficiency (the methylene blue degradation efficiency was nearly 50% in 10 min and the reaction rate constant was 0.

Choroidal neovascularization (CNV) is a leading cause of vision loss in ocular diseases, including age-related macular degeneration (AMD). Despite extensive research, the underlying mechanisms of CNV remain incompletely understood, with a predominant focus on endothelial dysfunction. CNV, however, is a multi-cellular, multi-stage process involving complex interactions between endothelial cells, monocytes/macrophages, and other immune cells.

Background: It has been shown that multiple metals exposure is associated with hyperuricemia. However, previous studies on the association and interaction between multiple metals exposure and hyperuricemia have been controversial, and there has been little evaluation of the potential mediating role of estimating glomerular filtration rate (eGFR).

Methods: In this study, levels of 12 metals in the urine of 3756 study participants were measured using Inductively Coupled Plasma Mass Spectrometry (ICP-MS).

Aims: To investigate the fundus characteristics and macular optical coherence tomography angiography (OCTA) metrics in patients with myelinated retinal nerve fibers (MRNF) and to identify the associations among myopic parameters, fundus metrics, and OCTA metrics.

Methods: The single-center case-control study included 15 patients with monocular MRNF and 15 patients without MRNF, matched for age, affected eyes' spherical equivalent error (SER), and axial length (AL) between May 2021 and December 2021. Fundus features, including the entire MRNF area (Area1), the denser MRNF area (Area2), and the shortest distance from the fovea to the MRNF border (D), along with ocular parameters, including SER, AL, best corrected visual acuity (BCVA), and OCTA metrics at the fovea, including choroidal (ChT) and retinal (ReT) thicknesses at the fovea, the foveal avascular zone area (FAZ), foveal avascular zone perimeter (FAZP), FAZ-circularity index (FAZ-CI), and foveal vessel density in a 300-µm wide region (FD-300), were assessed.

Riboflavin-5-phosphate (riboflavin) is the most commonly used photosensitizer in corneal crosslinking (CXL); while its efficient delivery into the stroma through the corneal epithelial barrier is challenging. In this paper, we presented novel responsive porous microneedles with ocular microinjection capability to deliver riboflavin controllably inside the cornea to facilitate CXL. The microneedle patch was composed of Poly (N-isopropyl acrylamide) (PNIPAM), graphene oxide (GO), and riboflavin-loaded gelatin.

Post-laser-assisted keratomileusis (LASIK) corneal ectasia is a severe complication of corneal refractive surgery, and cryopreserved lenticules from hyperopic small incision lenticule extraction (SMILE) may offer a promising treatment though their long-term safety and efficacy are still under investigation. In this prospective case series, six eyes from six patients with post-LASIK ectasia received lenticules (mean cryopreserved time: 63 days). The procedure involved lifting the corneal flap, implanting the lenticule, and repositioning the flap.

Background: Early identification of children at high risk of developing myopia is essential to prevent myopia progression by introducing timely interventions. However, missing data and measurement error (ME) are common challenges in risk prediction modelling that can introduce bias in myopia prediction.

Methods: We explore four imputation methods to address missing data and ME: single imputation (SI), multiple imputation under missing at random (MI-MAR), multiple imputation with calibration procedure (MI-ME), and multiple imputation under missing not at random (MI-MNAR).

To evaluate correlations of tumor PLK3 with clinical features and prognosis of resectable endometrial cancer (EC) patients. Tumor tissues from 200 EC patients receiving surgical resections and adjacent tissues from 50 of them were collected for PLK3 determination using immunohistochemistry. Tumor PLK3 negatively linked with myometrial invasion ≥50%, lymphovascular invasion, stromal cervical invasion, and International Federation of Gynecology and Obstetrics stage (all p < 0.

Microplastic (MP) pollution can exert significant pressure on soil ecosystems, however, the interactive effects of MPs on soil bacterial, fungal and protist communities remains poorly understood. Soil macrofauna, such as earthworms, can be directly affected by MPs, potentially leading to a range of feedbacks on the soil microbial community. To address this, we conducted a microcosm experiment to examine the effects of conventional (i.

Purpose: To evaluate changes of hydroxyproline concentration and its influencing factors of small incision lenticule extraction (SMILE)-derived corneal stromal lenticules with different preservation methods.

Methods: A total of 390 corneal stromal lenticules of 195 patients were derived from SMILE surgeries. Thirty of the lenticules were classified as the fresh (control) group, and the rest were randomly and evenly divided and stored in anhydrous glycerol, silicone oil, Optisol, and cryopreservation for 1 day, 1 week, or 1 month.

Chinese universities have placed increasing emphasis, on incorporating English as a medium of instruction (EMI) courses to enhance their competitiveness both nationally and internationally. However, the successful implementation of these courses requires learners to acquire content knowledge. To promote EMI courses, specific initiatives and policies have been put in place by universities reflecting a trend in the globalization of higher education and the growing demand for English proficiency in academic settings.

Background: Retinal detachment (RD) is a vision-threatening disorder of significant severity. Individuals with high myopia (HM) face a 2 to 6 times higher risk of developing RD compared to non-myopes. The timely identification of high myopia-related retinal detachment (HMRD) is crucial for effective treatment and prevention of additional vision impairment.

Purpose: To investigate topographical maps of the three-dimensional choroidal vascularity index (3D-CVI) in children with different levels of myopia.

Methods: We enrolled 274 eyes from 143 children with various severity of myopia, including emmetropia (EM), low myopia (LM), and moderate-high myopia (MHM). The choroidal vessel volume (CVV), choroidal stroma volume (CSV), and 3D-CVI in different eccentricities (fovea, parafovea, and perifovea) and quadrants (nasal, temporal, superior, and inferior) were obtained from swept-source optical coherence tomography angiography (SS-OCTA) volume scans.

Article Synopsis
  • Anemia significantly impacts the health of older adults, and its link to environmental metal exposure is not well understood, particularly regarding mixtures of metals rather than individual ones.
  • A study involving 3,781 participants analyzed 11 urinary metal concentrations and hemoglobin levels, using various statistical methods to assess the relationship between these metals and anemia.
  • Results indicated that several metals were associated with anemia, with tellurium being the most significant; however, this association varied based on factors like sex, obesity, and lifestyle choices.

Introduction: Dry eye (DE) is a multifactorial ocular surface disease causing considerable medical, social and financial implications. Currently, there is no recognised long-term, effective treatment to alleviate DE. Clinical evidence shows that electroacupuncture (EA) can improve DE symptoms, tear secretion and tear film stability, but it remains controversial whether it is just a placebo effect.
