purpose: to image leukocyte adherence to the vascular endothelium and extravasation into surrounding tissues in neovascularized corneas using acridine orange, a selective dna stain, in rats methods: corneal neovascularization was induced by placing two sutures in the cornea of one eye of 12 long-evans rats. one week later, acridine orange (4 mg/kg) was injected via the tail vein and the eyes we...

1,4-Naphthoquinone based chemosensors and detect only the presence of Cu(2+) ions among other transition metal ions by changing color from orange to dark blue. Chemosensors and function as tridentate ligands, which bind Cu(2+) ions through three functional groups: an amine nitrogen, a pyridine nitrogen and a quinone oxygen. On addition of Cu(2+), both and exhibit a 168 nm red shift in absorptio...

Foods that are high in citrate content generally are assumed to deliver alkali load when consumed irrespective of the accompanying cation. The object of this randomized, crossover study was to compare the effects of orange juice with those of lemonade on acid-base profile and urinary stone risks under controlled metabolic conditions. Thirteen volunteers (nine healthy subjects and four stone for...

The eruption of the orange glass magma to form the deposits sampled at the Apollo 17 site is considered to have been a gas-rich, fire-fountain eruption. The deposit consists entirely of small 1-2 mm spherical beads of the orange glass created during fragmentation of the magma. The data on the gas phase components in the pre-eruption A17 orange glass magma are constrained by C-O-S system phase e...

BACKGROUND 6',7'-Dihydroxybergamottin is a furanocoumarin that inhibits CYP3A4 and is found in grapefruit juice and Seville orange juice. Grapefruit juice increases the oral bioavailability of many CYP3A4 substrates, including cyclosporine (INN, ciclosporin), but intestinal P-glycoprotein may be a more important determinant of cyclosporine availability. OBJECTIVES To evaluate the contribution...

Sympatric orange-fronted (Cyanoramphus malherbi) and yellow-crowned parakeets (C. auriceps) were surveyed in a South Island beech (Nothofagus spp.) forest during the spring and summer of 1998/99. Habitat use, behaviour and diet were recorded for each parakeet identified. A single observer did all recording. Both species were seen most frequently in the upper-most 20% of the forest stratum. Oran...

The pericarp of Capsicum fruit is a rich dietary source of carotenoids. Accumulation of these compounds may be controlled, in part, by gene transcription of biosynthetic enzymes. The carotenoid composition in a number of orange-coloured C. annuum cultivars was determined using HPLC and compared with transcript abundances for four carotenogenic enzymes, Psy, LcyB, CrtZ-2, and Ccs determined by q...

Interferon regulatory factor 2 (IRF-2) is a multifunctional transcription factor which exhibits both transcriptional activating and repressing activities in the IRF family. In this study, we report an IRF-2 gene isolated from orange-spotted grouper (Epinephelus coioides). The 1854bp full-length cDNA sequence of EcIRF-2 has been cloned, encoding a putative peptide of 336 amino acids which is hig...

It has been said that the color of sputum from patients with Legionella pneumophila pneumonia is orange. However, why the color is orange has not been clarified. First, orange-colored sputum obtained from a patient with L. pneumophila pneumonia is presented. Then, the formation of an orange-colored pigment in a culture medium (without charcoal) after the growth of L. pneumophila is demonstrated.

this study was designed to investigate the effects of tangerine, orange, and grapefruit juice on the pharmacokinetic pattern of cyclosporine a in rats. forty male sprague-dawley rats were divided into four groups to receive water, orange, tangerine, or grapefruit juices respectively. water or juices (10 ml/kg) were given orally twice a day for 3 days. three hours after the 5 th dose, cyclospori...
