OBJECTIVE
Riboflavin-ultraviolet A (UVA) treatment induces cross-linking and stiffens the corneal stroma. A parallel reduction in stromal swelling and increased resistance to microbial and enzymatic degradation has been suggested. The purpose of this study was to evaluate the potential of
Oxidized irwN has been proposed as a mediator of the free radical-induced damage that occurs during cerebral ischemia. Dihydroriboflavin, a compound produced from riboflavin (B2) by NADPH-dependent flavin reductase, rapidly reduces oxidized iron. Since treatment with riboflavin offers protection
Previous studies have shown that administration of riboflavin, vitamin B2, significantly reduced edema formation following experimental stroke. The present study evaluated the ability of B2 to improve behavioral function, reduce edema formation, and limit glial fibrillary acidic protein (GFAP)
BACKGROUND
The effects induced by thiamine and riboflavin, isolated or in association with corticosteroids, in models of chronic inflammation are not known. Thus, we evaluated the effect induced by these B vitamins, isolated or in association with dexamethasone, on the mechanical allodynia, paw
OBJECTIVE
To present a case of acute idiopathic endotheliitis occurred early after corneal collagen cross-linking (CXL) for progressive keratoconus, and to discuss possible risk factors, causes, and other similar complications in the literature.
METHODS
A 24-year-old woman with bilateral keratoconus
Riboflavin, similar to other vitamins of the B complex, presents anti-inflammatory activity but its full characterization has not yet been carried out. Therefore, we aimed to investigate the effect of this vitamin in different models of nociception, edema, fever and formation of fibrovascular
An attempt was made to explore the scope of the bio-antioxidants in the management of symptoms of epidemic dropsy caused by argemone alkaloids, sanguinarine and dihydrosanguinarine. The study was performed on 24 randomly selected epidemic dropsy cases who consumed argemone contaminated mustard oil.
A strain of rapidly growing meat-type chickens was fed a diet deficient in riboflavin from 1-40 days of age. Diminished growth rate, progressive gait abnormality and reluctance to move were noted beginning on day 8. Neurologic abnormalities were related to peripheral neuropathy characterized by
OBJECTIVE
This study was undertaken to investigate the wound healing process of the first 6 weeks after photodynamic cross-linking treatment in the rabbit cornea, using the photosensitizer riboflavin and UVA.
METHODS
After removal of the central epithelium, the right corneas of 8 Chinchilla rabbits
Objective: To study the effects of ultraviolet light combined with riboflavin treatment (corneal collagen-crosslinking, CXL) on infectious control and stromal reconstruction of bacterial keratitis. Methods: Experimental Study. A Staphylococcus aureus rabbit keratitis model was
This study quantitatively investigated the immediate effects of a photooxidative collagen cross-linking treatment with photosensitizer riboflavin (RF) and 370 nm UVA light in in vitro human corneoscleral collagen fibrils using histology, thickness, scanning electron microscopy, and atomic force
OBJECTIVE
To assess ultrastructural modifications in keratocytes and inflammatory cell response in rabbit corneas after riboflavin and ultraviolet A exposure using immunofluorescence microscopy.
METHODS
Twenty adult New Zealand albino rabbits weighing 2.0–3.0 kg were used in this study. Two rabbits
OBJECTIVE
To describe a case of keratitis caused by the Gram-negative Escherichia coli, treated with UVA-riboflavin cross linking.
METHODS
Case report.
RESULTS
A 78-year-old woman with diabetes presented with a 1-week history of pain, photophobia, foreign body sensation, and lacrimation in the right
OBJECTIVE
To evaluate the safety and efficacy of staged ultraviolet A (UVA) cross-linking following intrastromal 0.1% riboflavin administration in eyes with advanced corneal edema.
METHODS
Ten eye bank corneas divided in two groups (n = 5) were placed on a pressurized artificial anterior chamber
