Metabolic fingerprints of proliferative diabetic retinopathy: an 1H-NMR-based metabonomic approach using vitreous humor.

Ignasi Barba et al.

Investigative ophthalmology & visual science, 51(9), 4416-4421 (2010-04-09)

To explore the metabolic profile of vitreous fluid of patients with proliferative diabetic retinopathy (PDR) using 1H-NMR-based metabonomic analysis. 1H-NMR spectra were acquired from vitreous samples obtained during vitrectomy from 22 patients with type 1 diabetes with PDR and from

Polyol formation in cell lines of rat retinal capillary pericytes and endothelial cells (TR-rPCT and TR-iBRB).

Peter F Kador et al.

Journal of ocular pharmacology and therapeutics : the official journal of the Association for Ocular Pharmacology and Therapeutics, 25(4), 299-308 (2009-05-20)

The two most widely investigated animal models for diabetic retinopathy (DR) are the rat and dog. In dogs, aldose reductase (AR) is present only in retinal capillary pericytes and their destruction has been linked to polyol accumulation and resulting apoptosis.

Galactose and galactitol in the urine of children with compound heterozygosity for Duarte variant and classical galactosemia (GtD/gt) after an oral galactose load.

H P Schwarz et al.

Clinical chemistry, 31(3), 420-422 (1985-03-01)

An oral dose of galactose, 1 g/kg of body weight, was administered to 24 children with the Duarte variant/classical galactosemia genetic compound (GtD/gt) and to 16 controls ranging in age from 0.3 to 10.7 years. Urine was then collected for

Stable isotope dilution analysis of galactitol in amniotic fluid: an accurate approach to the prenatal diagnosis of galactosemia.

C Jakobs et al.

Pediatric research, 18(8), 714-718 (1984-08-01)

A stable isotope dilution assay for galactitol in amniotic fluid has been developed using selected ion monitoring chemical ionization gas chromatography-mass spectrometry of the hexaacetate derivative. [1,1-2H2]Galactitol was synthesized for use as the internal standard. Galactitol is a component of
