Caveolin‐1 Stabilizes SERCA2 to Counteract Acute Kidney Injury via Suppression of Ca2+‐Dependent Endoplasmic Reticulum Stress in Distal Tubules

Advanced Science, EarlyView.
In AKI, initial kidney injury upregulates the expression of Cav‐1, which subsequently binds to and stabilizes SERCA2 via its scaffolding domain and through deubiquitination, thereby regulating Ca2+ homeostasis and ER stress. Conversely, Cav‐1 deficiency accelerates SERCA2 degradation, triggering Ca2+ overload and ER stress, and ultimately exacerbating ...

Imaging of retinal and choroidal vascular tumours [PDF]

Eye, 2012
The most common intraocular vascular tumours are choroidal haemangiomas, vasoproliferative tumours, and retinal haemangioblastomas. Rarer conditions include cavernous retinal angioma and arteriovenous malformations. Options for ablating the tumour include photodynamic therapy, argon laser photocoagulation, trans-scleral diathermy, cryotherapy, anti ...

ApoE‐ and Cfh‐deficient mice exhibit structural and molecular features of human early–intermediate retinal degeneration

Animal Models and Experimental Medicine, EarlyView.
Age‐related macular degeneration (AMD) involves lipid dysregulation and complement overactivation. Here, we characterize a double‐knockout ApoE−/−/Cfh−/− mouse as a model of early–intermediate retinal degeneration. These mice exhibit retinal pigment epithelium thinning, Bruch's membrane thickening, lipid accumulation, enhanced C5b‐9 deposition ...

A New Paradigm: 46 Structural Cell Types Function as Environment‐Supporting Innate Immune Cells, With Endothelial and Vascular Smooth Muscle Cells as Key Prototypes

iNew Medicine, EarlyView.
ABSTRACT The scope, organization, and biological significance of innate immune functions across structural cell types remain poorly defined. To address these fundamental knowledge gaps, we analyzed experimental data of transcriptomes generated by our group and others.

Quantitative analysis of retinal and choroidal microvascular changes in patients with diabetes

Scientific Reports, 2018
The relationship between choroidal and retinal microvascular changes has not yet been well described, and there were limited data on diagnostic ability of optical coherence tomography (OCT)-derived vascular parameters for determining diabetic retinopathy

Impact of 1024‐Matrix Size on Perforating Artery Visualisation in Cerebral Computed Tomography Angiography Using a 64‐Slice CT Scanner

Journal of Medical Radiation Sciences, EarlyView.
This study investigated whether using a larger image matrix (1024 × 1024 pixels instead of 512 × 512) improves the visibility of tiny brain arteries on CT scans performed with standard 64‐slice scanners. While physical image quality measurements remained unchanged, the larger matrix provided finer digital sampling of blood vessel structures, resulting ...
