What's the difference between xanthic and xanthous?
Xanthic
Definition:
(a.) Tending toward a yellow color, or to one of those colors, green being excepted, in which yellow is a constituent, as scarlet, orange, etc.
(a.) Possessing, imparting, or producing a yellow color; as, xanthic acid.
(a.) Of or pertaining to xanthic acid, or its compounds; xanthogenic.
(a.) Of or pertaining to xanthin.
Example Sentences:
(1) The dermal cells in grey, xanthic, and white goldfish integuments were cytochemically characterized for the following enzymatic activities: tyrosinase, DOPA-oxidase, cytochrome oxidase, monoamine oxidase, peroxidase, non-specific esterase, cholinesterase, NAD-diaphorase, NADP-diaphorase, aryl sulfatase, nucleotide phosphodiesterase, beta-glucuronidase, acid phosphatase, alkaline phosphatase, adenosine triphosphatase, thiamine pyrophosphatase, glucose-6-phosphatase, aldolase, as well as succinate, malate, isocitrate, glutamate, glucose-6-phosphate, 6-phosphogluconate, alpha-glycerophosphate, alcohol, lactate, and beta-hydroxybutyrate dehydrogenases.
(2) Tyrosinase was not identified cytochemically; however, the enzyme was demonstrated biochemically in the pigment epithelia of both albino and xanthic goldfish.
(3) Integumental erythrophores on the scales of xanthic goldfishes were dissociated and cultured in a monolayer for about 30 days.
(4) Ultrastructural studies, and cytochemical and biochemical determinations of tyrosinase activity were conducted on the pigment epithelium of albino and xanthic goldfish eyes.
(5) Melanosomes in xanthic mollies appear to develop by one of two pathways: 1) from an endoplasmic reticulum-derived vesicle which develops an internal lamellar framework, and 2) by fusion of multiple Golgi-derived vesicles which lack an internal lamellar framework.
(6) This is consistent with the fact that xanthic mollies have been shown to be tyrosinase positive.
(7) Analysis of the pigments in the skin of the xanthic mollies identified four colorless pteridine pigments (xanthopterin, isoxanthopterin, neopterin, and pterin) and a carotenoid with an absorbance spectrum similar to beta-carotene.
(8) In eyes of xanthic goldfish, two types of melanosomes are present, spherical and elongated.
(9) The authors report on 136 cases of arterial occlusion (80 patients suffering from occlusion of the retinal vessels and 56 patients with vascular occlusion in the optic nerve) who were treated with the vasoactive xanthic substance Pentoxifylline (Trental).
(10) This result can explain after nightly theophylline injection (where renal functions are already very higher than in daily period) the so small nightly proteinuria increase with the xanthic diuretic ; it cannot be compared to the daily value, because the renal functions cannot increase beyond some limits.
(11) After confirmation of the intense and very fast myorelaxant effect of theophylline on isolated glomeruli, xanthic reagent myotoxic effects are shown during more or less long contacts with these glomerular suspensions.
(12) 56 xanthic lithiases have been published and since the work of Dent and Philpot, 28 xanthinurias have been reported.
(13) Tyrosinase inhibitors are present in the particulate fractions of both albino and xanthic goldfish eyes.
(14) Electron micrographs of skin from xanthic (gold) sailfin mollies revealed numerous xanthophores, as well as scattered melanophores.
(15) Internal vesicles are present in both melanosome types in the pigment epithelium of the xanthic goldfish but are absent in premelanosomes of the albino.
(16) Thereafter it begins to show a characteristic xanthic coloration.
Xanthous
Definition:
(a.) Yellow; specifically (Ethnol.), of or pertaining to those races of man which have yellowish, red, auburn, or brown hair.
Example Sentences:
(1) Based on 5 individual cases over a period of 8 years (1 fibroma, 1 angiofibroma, 2 adenofibromas, 1 xanthous neurofibroma) the characteristics of the rare intrapulmonary fibroma and the therapeutic consequences are discussed.
