Non‐invasive and efficient diabetic retinal mitochondrial repair nanoplatform based on engineered endothelial mitochondrial‐derived vesicles with dynamic integrated stress response modulation

open access: yesInterdisciplinary Medicine, EarlyView.
Under hyperglycemic conditions, mitochondrial dysfunction in retinal endothelial cells triggers excessive reactive oxygen species/reactive nitrogen species production, barrier protein degradation, and endothelial barrier breakdown in diabetic retinopathy.

Efeito da posição do bisel da caneta de facoemulsificação no endotélio corneano [PDF]

open access: yes, 2010
Purpose: To compare the extent of corneal endothelial (CE) cell loss changes in two groups of eyes submitted to phacoemulsification, with the conventional bevel-up tip position in one eye and with the bevel-down tip position in the fellow eye.

Overview of Diagnostic Ultrasound Safety

open access: yesJournal of Ultrasound in Medicine, EarlyView.
Ultrasound is widely regarded as a safe imaging modality; however, emerging ultrasound‐based techniques—such as shear wave elastography and contrast‐enhanced ultrasound—operate with varying acoustic output parameters that may approach or exceed traditional diagnostic limits. As these technologies are increasingly integrated into human research studies,

Effects of Laser In Situ Keratomileusis on the Corneal Endothelium

open access: yesKaohsiung Journal of Medical Sciences, 2005
The purpose of this study was to assess the effects of laser in situ keratomileusis (LASIK) on the corneal endothelium. In a prospective study, the corneal endothelium of 87 eyes (45 patients) was examined before and 1 month after LASIK.

Efeito do epitélio na absorção corneana de raios ultravioleta-A e riboflavina [PDF]

open access: yes, 2011
PURPOSE: To determine if the corneal epithelium prevents the collagen cross-linking effect. Using immunofluorescence microscopy after CXL, we indirectly analyzed the role of the epithelium as ultraviolet-A (UVA) shield as well as a barrier to riboflavin ...

Alogliptin Reduces Oxidative Stress in Cardiomyocytes and Ameliorates Diabetic Cardiomyopathy via the AURKB/NLGN2 Signaling

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Diabetic cardiomyopathy (DCM) is a common complication of diabetes mellitus. This study investigated the effects of alogliptin on DCM and its underlying mechanisms. A DCM model was constructed and treated with alogliptin. Downstream targets of alogliptin were screened using bioinformatics analysis.

Overexpression of MMPs in Corneas Requiring Penetrating and Deep Anterior Lamellar Keratoplasty. [PDF]

open access: yes, 2019
PurposeMatrix metalloproteinases (MMPs) comprise a family of zinc-dependent endopeptidases involved in wound healing processes, including neovascularization and fibrosis. We assessed MMP protein expression levels in diseased corneas of patients requiring

Extracellular Vesicle‐Mediated Communication Between Anterior Cruciate Ligament and Bone Marrow Cells Modulates Hamstring Tenocyte Behavior and Apoptosis

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Following anterior cruciate ligament (ACL) reconstruction, enhancing hamstring tenocyte activity and minimizing apoptosis are critical for preventing graft failure and promoting ligamentization. This study investigated the therapeutic potential of extracellular vesicles (EVs) derived from a coculture of ACL remnant cells and bone marrow ...

Sleep deprivation induces corneal endothelial dysfunction by downregulating Bmal1

open access: yesBMC Ophthalmology
Background Sleep deprivation (SD) is a common public health problem that contributes to various physiological disorders and increases the risk of ocular diseases. However, whether sleep loss can damage corneal endothelial function remains unclear.
