circSIRT2/miR-542-3p/VASH1 axis regulates endothelial-to-mesenchymal transition (EndMT) in subretinal fibrosis in age-related macular degeneration models.

Neovascular age-related macular degeneration (nAMD), characterized by choroidal neovascularization (CNV), is one of the leading causes of severe visual impairment and irreversible vision loss around the world. Subretinal fibrosis (SRF) contributes to the incomplete response to anti-vascular endothelial growth factor (VEGF) treatment and is one of the main reasons for long-term poor visual outcomes in nAMD. Reducing SRF is urgently needed in the anti-VEGF era.

ABHD1 Facilitates Intermediate Filament-Mediated Endothelial Cell Chemotaxis by Regulating KRT1 and KRT2 in Diabetic Retinopathy.

Diabetic retinopathy (DR) is one of the most common complications of diabetes and induces severe visual impairment worldwide. Endothelial cell dysfunction plays an important role in the pathogenesis of DR. Here, we keep a watchful eye on /-hydrolase domain-containing 1 (ABHD1), a potential regulator in lipid metabolism and neovascularization.

Prediction model for ocular metastasis of breast cancer: machine learning model development and interpretation study.

Background: Breast cancer (BC) is caused by the uncontrolled proliferation of breast epithelial cells followed by malignant transformation, and it has the highest incidence among female malignant tumors. The metastasis of BC occurs through direct and lymphatic spread. Although ocular metastasis is relatively rare, it is a good indicator of a worse prognosis.

UPLC-MS/MS-based serum metabolomics analysis for comprehensive pathological myopia profiling.

Pathological myopia (PM) is associated with ocular morbidities that cause blindness. PM often occurs in eyes with high myopia (HM) while they are distinctly different. Identifying the differences in metabolites and metabolic pathways between patients with PM and HM may provide information about the pathogenesis of PM, which is currently unknown.

OCTA evaluates changes in retinal microvasculature in renal hypertension patients.

The objective of this study is to utilize optical coherence tomography angiography (OCTA) techniques for the purpose of identifying abnormalities in retinal and conjunctival vascular density among patients afflicted with renal hypertension. From October 2022 to October 2023, a cohort of sixteen patients diagnosed with renal hypertension (RH), comprising a total of 32 eyes, was selected from the Department of Nephrology at the First Affiliated Hospital of Nanchang University. Concurrently, a group of sixteen healthy individuals, carefully matched in characteristics, was recruited from volunteers at the Ophthalmology Research Center and designated as the healthy controls (HCs) group.

The adaptive immune system in the retina of diabetics.

As the prevalence of diabetes mellitus increases each year, its most common microvascular complication, diabetic retinopathy (DR), is also on the rise. DR is now regarded as an inflammatory disease in which innate immunity plays a crucial role, and a large number of innate immune cells with associated cytokines are involved in the pathologic process of DR. The role of adaptive immunity in DR is seldom mentioned, probably due to the general perception of the immune privileged environment of the retina; however, in recent years there has been a gradual increase in research on the role of adaptive immunity in DR, and with the discovery of the retinal lymphatic system, it seems that the role of adaptive immunity can no longer be ignored.

A highly sensitive electrochemical aptasensor for detecting broad-spectrum estrogen molecules in clinical samples.

The lack of sensitive and accurate monitoring methods for in vivo estrogen levels presents challenges for better prevention of estrogen-induced diseases. We have developed a label-free electrochemical aptasensor that demonstrates high sensitivity and selectivity for the broad-spectrum detection of estrogen molecules. This biosensor uses gold nanoparticles for electrochemical signal amplification and aptamers for broad-spectrum target recognition, enabling precise detection of trace amounts of estrogen in serum samples.

Aberrant Lipid Metabolism and Complement Activation in Age-Related Macular Degeneration.

Age-related macular degeneration (AMD) stands as a leading cause of severe visual impairment and blindness among the elderly globally. As a multifactorial disease, AMD's pathogenesis is influenced by genetic, environmental, and age-related factors, with lipid metabolism abnormalities and complement system dysregulation playing critical roles. This review delves into recent advancements in understanding the intricate interaction between these two crucial pathways, highlighting their contribution to the disease's progression through chronic inflammation, drusen formation, and retinal pigment epithelium dysfunction.

Therapeutic Effects of Metformin on Central Nervous System Diseases: A Focus on Protection of Neurovascular Unit.

Metformin is one of the most commonly used oral hypoglycemic drugs in clinical practice, with unique roles in neurodegeneration and vascular lesions. Neurodegeneration and vasculopathy coexist in many diseases and typically affect the neurovascular unit (NVU), a minimal structural and functional unit in the central nervous system. Its components interact with one another and are indispensable for maintaining tissue homeostasis.

[Emerging challenges in the application of artificial intelligence for the eye disease screening in Chinese primary healthcare institutions].

Breakthroughs have been achieved recently in the application of artificial intelligence (AI) for the eye disease screening in Chinese primary healthcare institutions, but challenges have also emerged.
