Disease relevance of Triturus

• Specimens of Triturus cristatus carnifex (Laurenti), raised in 3.2 g/l solution of sodium lactate, presented hypertrophy of "lactate sensitive cells" (LSC) clustered at the vascular pole of each renal corpuscle [1].

High impact information on Triturus

• This study describes analysis of this axon regeneration over time following deviation of the forearm flexor nerve in Triturus cristatus and the extensor cranialis nerve in the axolotl [2].
• Nuclear RNP from Triturus oocytes is organized as strings of beads which can be converted into 20-nm-diameter monoparticles with mild RNase treatment or into 5-nm-thick linear fibrils with low salt treatment [3].
• A protein equivalent of TFIIIA is not found in 5S RNA-containing RNP storage particles of Triturus oocytes [4].
• The stimulation of both alpha and beta adrenoreceptors reduced the numbers of S+ rosettes formed by Triturus and Cynops lymphocytes, whereas a beta agonist increased and an alpha agonist decreased S+ rosette formation by Rana and Xenopus splenic lymphocytes [5].
• In vitro nitric oxide effects on basal and gonadotropin-releasing hormone-induced gonadotropin secretion by pituitary gland of male crested newt (Triturus carnifex) during the annual reproductive cycle [6].

Biological context of Triturus

• DNA reassociation kinetics were studied, by means of the hydroxyapatite chromatography method, for four species of Amphibians with different nuclear DNA content: Xenopus laevis (3 pg DNA per haploid genome) and Bufo bufo (7 pg) of the Anura subclass and Triturus cristatus (23 pg) and Necturus maculosus (52 pg) of the Urodela subclass [7].
• Corticosterone during the annual reproductive cycle and in sexual behavior in the crested newt, Triturus carnifex [8].
• Effect of D-glucose on oxygen consumption of renal proximal tubules of the Triturus [9].
• The effect of 5 alpha-dihydrotestosterone and 5 beta-dihydrotestosterone on erythropoiesis of the newt, Triturus cristatus carnifex (Laur.) [10].
• The technique of stationary microperfusion of the early distal tubule used in experiments on male newts (Triturus vulgaris) revealed the intratubular effect of CoCl2 and furosemide on the ion transport [11].

Anatomical context of Triturus

• Immunohistochemical localization of corticotropin-releasing factor (CRF)-like immunoreactivity in the hypothalamus of the newt, Triturus cristatus [12].
• Annual changes in the number, testosterone content and ultrastructure of glandular tissue cells of the testis in the marbled newt Triturus marmoratus [13].
• The interactions between thyroid hormones and receptors for steroid hormones and prolactin in dorsal skin and caudal fin of Triturus cristatus carnifex were studied during the annual cycle [14].
• Vitamin A induced bilateral asymmetries in triturus forelimb regenerates [15].
• The newt Triturus carnifex as a model for monitoring the ecotoxic impact of the fungicide thiophanate methyl: adverse effects on the adrenal gland [16].

Associations of Triturus with chemical compounds

• Distribution of substance P-like immunoreactivity in the brain of the newt (Triturus cristatus) [17].
• These results suggest that 9-ketoreductase and PGF2 alpha enhance aromatase activity to trigger male Triturus carnifex courtship [18].
• Castration significantly lowers serum testosterone in sexually active male Triturus cristatus [19].
• These data suggest that in Triturus carnifex prostaglandin E2 increases testicular androgens synthesis via phospholipase C at reproduction beginning; on the contrary, this prostaglandin decreases androgens via adenylate cyclase at reproduction ending [20].
• Plasma testosterone and 17 beta-estradiol concentrations, and aromatase activity, during courtship in male Triturus carnifex [21].

Gene context of Triturus

• In the early distal tubule of the newt Triturus vulgaris L., 1 nM arginine-vasopressin (AVP) increased water reabsorption; the fractional reabsorption of Na+ was elevated from 46.2 +/- 6.9% to 67.8 +/- 3.9% (P < 0.001), of Cl- from 52.7 +/- 6.7% to 73.1 +/- 3.5% (P < 0.001), of Mg2+ from 48.0 +/- 7.7% to 71.7 +/- 6.3% (P < 0.001) [22].
• PCNA positivity in the telencephalic matrix areas in the adult of a newt, Triturus carnifex [23].
• Organization of tyrosine-hydroxylase immunopositive neurons in the brain of the crested newt, Triturus cristatus carnifex [24].
• Heterochromatic DNA in Triturus (Amphibia, Urodela) II. A centromeric satellite DNA [25].
• These results suggest that SP downregulates gonadotropin release in both Triturus carnifex sexes [26].

Analytical, diagnostic and therapeutic context of Triturus

• The distribution of neuronal and non-neuronal mRNAs for alpha7 and alpha4 nicotinic acetylcholine receptor subunits was investigated in Triturus carnifex tissues using the in situ hybridization approach [27].
• Autoradiographic studies on Triturus alpestris regenerates treated with vitamin A palmitate for 4, 7, 11 and 14 days after amputation, reveal a considerable diminution in the percentage of cells duplicating DNA, as judged by measurements of labelling indices [28].
