Purpose: To evaluate serum and aqueous humor levels of fetuin-A in patients with pseudoexfoliation syndrome (PEXS) in comparison with those of age- and sex-matched healthy subjects.

Materials And Methods: This prospective study included 25 patients with PEXS and 25 control subjects who were undergoing cataract surgery without any systemic or ocular disease. Aqueous humor and serum fetuin-A levels were measured with enzyme-linked immunosorbent assay method.

Results: The mean age of the PEXS group (14 males, 11 females, n = 25) was 57.7 ± 6.9 years, and the control group (13 males, 12 females, n = 25) was 58.1 ± 5.7 years. There was no difference between the groups in terms of age (p = 0.77) and sex (p = 0.83). The mean serum fetuin-A level of the PEXS group did not differ from that of the control group (p = 0.53). The mean aqueous humor level of the PEXS group was significantly higher than that of the control group (p = 0.032). There were no significant correlations between aqueous humor and serum fetuin-A levels among patients with PEXS and control group (p > 0.05).

Conclusions: Increased levels of fetuin-A in aqueous humor of patients with PEXS may show the local effect of fetuin-A on the anterior segment. With considering the wide range of possible biological functions of fetuin-A in the pathogenesis of PEXS, further studies are needed to clarify the clinical relevance of these findings.

Intraocular pressure (IOP) plays a crucial role in glaucoma development, involving the dynamics of aqueous humor (AH). AH flows in from the ciliary body and exits through the trabecular meshwork (TM). IOP follows a circadian rhythm synchronized with the suprachiasmatic nucleus (SCN), the circadian pacemaker.

Dexamethasone (Dex) is a primary medication for treating dry eye syndrome, and tobramycin-dexamethasone eye drops are commercially available. However, the eye's complex physiological environment reduces its bioavailability, and repeated use can lead to significant systemic toxicity and side effects. This study introduces a novel conjugate of chitosan (CS) and N-acetylcysteine (NAC), a bioadhesive material, which was grafted onto the surface of a Dex-supported nanostructured lipid carrier (NLC) to develop an innovative nanoparticle lipid ocular drug delivery system (CS-NAC@Dex-NLC).

Lanthanide Metal-Organic Framework Flowers for Proteome Profiling and Biomarker Identification in Ultratrace Biofluid Samples.

Identifying effective biomarkers has long been a persistent need for early diagnosis and targeted therapy of disease. While mass spectrometry-based label-free proteomics with trace cell has been demonstrated, deep proteomics with ultratrace human biofluid remains challenging due to low protein concentration, extremely limited patient sample volume, and substantial protein contact losses during preprocessing. Herein, we proposed and validated lanthanide metal-organic framework flowers (MOF-flowers), as effective materials, to trap and enrich protein in biofluid jointly through cation-π interaction and O-Ln coordination.

Introduction: Uveitis, a severe inflammatory disease affecting the uvea, is associated with visual impairment and irreversible blindness. Asperulosidic Acid (ASPA), derived from , is known for its notable anti-inflammatory and antioxidant characteristics.

Methods: The present study explored the potential anti-inflammatory effects and the fundamental processes of ASPA by injecting it or a placebo into the vitreous of rats with endotoxin-induced uveitis (EIU).
