| anatomical and electrophysiological evidence for gabaergic bipolar cells in tiger salamander retina. | our previous work showed that about 12% of bipolar cells in salamander retina synthesize and take up gamma-aminobutyric acid (gaba), are gaba transporter (gat)-immunoreactive, and respond with a gat current to extracellularly applied gaba, suggesting that these bipolar cells use gaba, in addition to glutamate, as a neurotransmitter. further support for this idea was obtained in this study by use of immunogold electron microscopy and whole-cell patch clamp electrophysiology. ultrastructural analy ... | 1999 | 10746135 |

| effects of genetic structure of lupinus arboreus and previous herbivory on platyprepia virginalis caterpillars. | two leaf-feeding caterpillars, western tussock moth (orgyia vetusta) and ranchman's tiger moth (platyprepia virginalis) are abundant on lupinus arboreus along the california coast. previous experiments and observations suggested that feeding caused by either of these two folivores could reduce the performance and possibly the abundance and distribution of the other species. previous common garden experiments also indicated that genetically determined characteristics of the host plants were impor ... | 1999 | 28308088 |
| do images involuntarily trigger search? a test of pillsbury's hypothesis. | pillsbury (1908) suggested that deciding to search for something in a scene consists of nothing more than forming a visual image of the target. if so, imaging should trigger search even when it would be more advantageous not to search. subjects were cued to form an image of a specified object (e.g., tiger) and to press a key when they had done so. this initiated the presentation of a sequence of pictures, with a single target digit interspersed; the subject's task was to report this digit. the s ... | 1999 | 12198782 |
| anaesthesia of a sumatran tiger on eight occasions with ketamine, medetomidine and isoflurane. | an 18-month-old male sumatran tiger was referred for endoscopy and dilatation of an oesophageal stricture. anaesthesia and bouginage was undertaken on eight occasions 2-3 weeks apart to dilate the oesophageal stricture. | 1999 | 16032083 |
| materials science: new tigers in the fuel cell tank. | after decades of incremental advances, a spurt of findings suggests that fuel cells that run on good old fossil fuels are almost ready for prime time. although conventional ceramic cells, known as solid oxide fuel cells, require expensive heat-resistant materials, a new generation of sofcs, including one featured on page 2031, converts hydrocarbons directly into electricity at lower temperatures. and a recent demonstration of a system of standard sofcs large enough to light up more than 200 home ... | 2000 | 17835104 |
| amacrine cells of the anuran retina: morphology, chemical neuroanatomy, and physiology. | amacrine cells are third-order retinal interneurons, projecting their processes into the inner plexiform layer. historically, they were not considered as neurons first. by the middle of the 20th century, their neuronal nature was confirmed, and their enormous diversity established. amacrine cells have been most successfully subdivided into morphological categories based on two parameters: diameter of the dendritic field and ramification pattern in the inner plexiform layer. works combining anato ... | 2000 | 10941173 |
| fractionation and characterization of mushroom dietary fiber (nonstarch polysaccharides) as potential nutraceuticals from sclerotia of pleurotus tuber-regium (fries) singer. | the nonstarch polysaccharides (nsps) in the total dietary fiber (tdf) from the sclerotia of pleurotus tuber-regium (tiger milk mushroom) were fractionated by the sequential use of chemical solvents. about half of the tdf was solubilized and two major alkali-soluble fractions (1 and 4 n sodium hydroxide) that contained 126 and 293 g/kg tdf were obtained. sugar analysis and infrared spectroscopy indicated that the nsps in these alkali-soluble fractions were mainly beta-glucans and chitin. these al ... | 2000 | 10956083 |
| denoising of electron beam monte carlo dose distributions using digital filtering techniques. | the monte carlo (mc) method has long been viewed as the ultimate dose distribution computational technique. the inherent stochastic dose fluctuations (i.e. noise), however, have several important disadvantages: noise will affect estimates of all the relevant dosimetric and radiobiological indices, and noise will degrade the resulting dose contour visualizations. we suggest the use of a post-processing denoising step to reduce statistical fluctuations and also improve dose contour visualization. ... | 2000 | 10943918 |
| anoxia tolerance of con-familial tiger beetle larvae is associated with differences in energy flow and anaerobiosis. | in this study, we compared survivorship, heat dissipation and biochemical features of anaerobiosis of two tiger beetle species (coleoptera: cicindelidae) exposed to anoxia. one species commonly experiences environmental immersion from rainfall and snowmelt (cicindela togata), and the habitat of the other (amblycheila cylindriformis) is not prone to flooding. the ancestral genus, a. cylindriformis, survives anoxia for only 2 days at 25 degrees c. in response to anoxia, these larvae immediately lo ... | 2000 | 10935521 |
| effect of 11-cis 13-demethylretinal on phototransduction in bleach-adapted rod and cone photoreceptors. | we used 11-cis 13-demethylretinal to examine the physiological consequences of retinal's noncovalent interaction with opsin in intact rod and cone photoreceptors during visual pigment regeneration. 11-cis 13-demethylretinal is an analog of 11-cis retinal in which the 13 position methyl group has been removed. biochemical experiments have shown that it is capable of binding in the chromophore pocket of opsin, forming a schiff-base linkage with the protein to produce a pigment, but at a much slowe ... | 2000 | 10919871 |
| foraging under the risk of cannibalism leads to divergence in body size among tiger salamander larvae. | populations of plants and animals are almost always made up of individuals of different sizes. in populations where cannibalism is common, this size variation can influence rates of mortality and growth and affect population regulation. size variation can be caused by a variety of mechanisms. one of these is due to size-specific responses to the threat of predation by potentially cannibalistic conspecifics. we investigated the role of anti-predator behavior in size structure development within s ... | 2000 | 28308182 |
| depolarization-induced calcium channel facilitation in rod photoreceptors is independent of g proteins and phosphorylation. | depolarization-induced facilitation of l-type ca channels in rod photoreceptors was investigated with nystatin-perforated and ruptured whole cell patch-clamp techniques in cells isolated from tiger salamander retina. induction of facilitation was voltage dependent with a half-maximal effect seen at prepulse potentials near +31 mv. reversal of facilitation was time dependent with fast (tau approximately 20 ms) and slow (tau approximately 1 s) components at -60 mv. incubation of cells with pertuss ... | 2000 | 10899191 |
| temperatures in the cothill habitat of panaxia (callimorpha) dominula l. (the scarlet tiger moth). | temperatures were monitored in precisely the places in cothill fen in which larvae of panaxia dominula pupate. at the critical time in june, the temperatures in the litter layer are diurnally often much higher than those used in previous constant temperature experiments. moreover, the daily mean temperature in the shaded litter layer is also higher than the shaded air temperature at 0.4 m, both temperatures being higher than the estimate of 12 degrees c used as baseline by others. the effects of ... | 2000 | 10849083 |

| caudal cervical disc protrusion in a bengal tiger (panthera tigris tigris). | a young adult male white bengal tiger (panthera tigris tigris) presented with hindlimb ataxia. cervical and lumbar myelography revealed a compressive lesion of the cord at c(6-7). corticosteroid therapy and confinement failed to provide lasting remission of signs. a modified, inverted cone ventral slot decompression was used to remove the fibrous material causing cord compression at c(6-7). temporary horner's syndrome and laryngeal paresis developed postsurgically because of excessive tissue ret ... | 2000 | 11237151 |
| [hallervorden-spatz disease: findings in the nigrostriatal system]. | hallervorden-spatz disease (hsd), a rare extrapyramidal motor illness, is usually only confirmed after death. in vivo diagnosis has relied hitherto on the combination of typical magnetic resonance imaging (mri) findings (the "eye of the tiger" sign) and heterogeneous clinical symptoms of movement disorder which have been regarded as almost pathognomonic. we report on the diagnostic contribution of 123j-beta-cit single photon emission computed tomography (spect) and 123j-ibzm spect in akinetic-ri ... | 2000 | 10996917 |

| candidate gene analysis of thyroid hormone receptors in metamorphosing vs. nonmetamorphosing salamanders. | we used two different experimental approaches to test the hypothesis that thyroid hormone receptor (tr) variation is associated with alternate life cycles modes in ambystomatid salamanders. in the first experiment, the inheritance of tralpha and trbeta genotypes was determined for metamorphic and non metamorphic offspring from backcrosses between ambystoma mexicanum (an obligate metamorphic-failure species) and metamorphic f1 hybrids (a. mexicanum x a. tigrinum tigrinum). the segregation of tr g ... | 2000 | 11012711 |
| intrafamilial phenotypic variability of hallervorden-spätz syndrome in a tunisian family. | we report clinical features, ct-scan and mri findings of three siblings with hallervorden-spätz disease, one of them followed for more than 20years. patient 1 presented at age 10 with progressive generalized dystonia. five years later she had violent dystonic spasms with opisthotonos and marked oro-mandibular involvement. later, dystonia stabilized and examination showed dysarthria, multiple deformities related to dystonic posturing, retinal degeneration and no cognitive impairment. cerebral ct- ... | 2000 | 10817958 |
| i4aa-sensitive chloride current contributes to the center light responses of bipolar cells in the tiger salamander retina. | light-evoked currents in depolarizing and hyperpolarizing bipolar cells (dbcs and hbcs) were recorded under voltage-clamp conditions in living retinal slices of the larval tiger salamander. responses to illumination at the center of the dbcs' and hbcs' receptive fields were mediated by two postsynaptic currents: deltai(c), a glutamate-gated cation current with a reversal potential near 0 mv, and deltai(cl), a chloride current with a reversal potential near -60 mv. in dbcs deltai(c) was suppresse ... | 2000 | 10848563 |
| the molecular basis of melanism and mimicry in a swallowtail butterfly. | melanism in lepidoptera, either industrial or in mimicry, is one of the most commonly cited examples of natural selection [1] [2]. despite extensive studies of the frequency and maintenance of melanic genes in insect populations [1] [2], there has been little work on the underlying molecular mechanisms. nowhere is butterfly melanism more striking than in the eastern tiger swallowtail (papilio glaucus) of north america [3] [4] [5]. in this species, females can be either yellow (wild type) or blac ... | 2000 | 10837223 |
| triggering of cryoprotectant synthesis in the woolly bear caterpillar (pyrrharctia isabella lepidoptera: arctiidae). | isabella tiger moths (pyrrharctia isabella) overwinter as caterpillars (i.e., woolly bears) that can survive freezing at moderate subzero temperatures. we observed an increase in hemolymph osmolality for field-collected woolly bears during october (325 +/- 47 to 445 +/- 27 mosmol/liter) and tested the influence of temperature and moisture levels on cryoprotectant production. laboratory acclimation was done at 5 degrees c in moist conditions and at 25 degrees c acclimation in both dry and moist c ... | 2000 | 10684559 |
| fraction of the dark current carried by ca(2+) through cgmp-gated ion channels of intact rod and cone photoreceptors. | the selectivity for ca(2+) over na(+), pca/pna, is higher in cgmp-gated (cng) ion channels of retinal cone photoreceptors than in those of rods. to ascertain the physiological significance of this fact, we determined the fraction of the cyclic nucleotide-gated current specifically carried by ca(2+) in intact rods and cones. we activated cng channels by suddenly (<5 ms) increasing free 8br-cgmp in the cytoplasm of rods or cones loaded with a caged ester of the cyclic nucleotide. simultaneous with ... | 2000 | 11099344 |
| competition between the gypsy moth, lymantria dispar, and the northern tiger swallowtail, papilio canadensis: interactions mediated by host plant chemistry, pathogens, and parasitoids. | the gypsy moth, lymantria dispar, and the northern tiger swallowtail, papilio canadensis, overlap geographically as well as in their host ranges. adult female swallowtails are incapable of distinguishing between damaged and undamaged leaves, and the opportunities for competition between these two species are numerous. we designed field and laboratory experiments to look for evidence of indirect competition between p. canadensis and l. dispar larvae. swallowtail caterpillars were reared in the la ... | 2000 | 24595833 |
| three levels of lateral inhibition: a space-time study of the retina of the tiger salamander. | the space-time patterns of activity generated across arrays of retinal neurons can provide a sensitive measurement of the effects of neural interactions underlying retinal activity. we measured the excitatory and inhibitory components associated with these patterns at each cellular level in the retina and further dissected inhibitory components pharmacologically. using perforated and loose patch recording, we measured the voltages, currents, or spiking at 91 lateral positions covering approximat ... | 2000 | 10684895 |
| developmental study of the shortened spinal cord in the adult tiger puffer fish, takifugu rubripes (teleostei). | abstract the spinal cords of vertebrates are generally divided into the cord proper and the minute filum terminale. while the spinal cord extends the entire length of the vertebral canal in the adult tiger puffer, takifugu rubripes, the cord proper is greatly reduced in length and almost all of the canal is occupied by the filum terminale, which is tape-like rather than thread-like. the dorsal and ventral roots of the spinal nerves extend, respectively, above and below the filum terminale; as a ... | 2000 | 10723077 |
| how slippage-derived sequences are incorporated into rrna variable-region secondary structure: implications for phylogeny reconstruction. | we analyzed the type and frequency of mutational changes in hypervariable rrna regions, using the highly length-variable region v4 of the small subunit rrna locus of tiger beetles (cicindelidae) as an example. phylogenetic analysis of indels in closely related species showed that (1) most indels are single nucleotides (usually a or t and sometimes g) or di-nucleotides of a and t. these occur at numerous foci, and they exhibit a strong bias for duplication of 5' single and di-nucleotide motifs bu ... | 2000 | 10712842 |
| effects of betaxolol on light responses and membrane conductance in retinal ganglion cells. | to examine the physiological effects of betaxolol, a beta1-adrenergic receptor blocker commonly used in the treatment of glaucoma, on retinal ganglion cells and to evaluate its potential to elicit responses consistent with a neuroprotective agent against ganglion cell degeneration. | 2000 | 10711687 |
| gaba(c) receptors control adaptive changes in a glycinergic inhibitory pathway in salamander retina. | we studied the role of gaba in adaptive changes in a lateral inhibitory system in the tiger salamander retina. in dark-adapted retinal slice preparations picrotoxin caused a slow enhancement of glycine-mediated ipscs in ganglion cells. the enhancement of glycinergic ipscs developed slowly over the course of 5-20 min, even though picrotoxin blocked both gaba(a) and gaba(c) receptors within a few seconds. the slow enhancement of glycinergic ipscs by picrotoxin was much weaker in light-adapted prep ... | 2000 | 10632610 |
| dosimetry characterization of 32p catheter-based vascular brachytherapy source wire. | dosimetry measurements and monte carlo simulations for a catheter-based 32p endovascular brachytherapy source wire are described. the measured dose rates were obtained using both radiochromic dye film and an automated plastic scintillator. the investigated source has dimensions of 27 mm in length and 0.24 mm in diameter, and is encapsulated in niti. for the radiochromic film measurements, calibrated radiochromic dye film was irradiated at distances between 1 and 5 mm from the source axis in a-15 ... | 2000 | 10984223 |
| misfolding of membrane proteins in health and disease: the lady or the tiger? | protein misfolding is increasingly recognized as a factor in many diseases, including cystic fibrosis, parkinson's, alzheimer's and atherosclerosis. many proteins involved in misfolding-based pathologies are membrane-associated, such that the bilayer may play roles in normal and aberrant folding. it can be argued that the in vivo partitioning of eukaryotic membrane proteins between folding and misfolding pathways is under kinetic control. moreover, the balance between these pathways can be surpr ... | 2000 | 10981632 |
| dihydropyridine-sensitive calcium currents in bipolar cells of salamander retina are inhibited by reductions in extracellular chloride. | dihydropyridine-sensitive calcium currents (i(ca)) in photoreceptors are unusual in that they can be inhibited by reductions in extracellular chloride. the present study examined whether i(ca) in retinal bipolar cells, which as in photoreceptors mediates sustained neurotransmission, is also inhibited by reductions in chloride. nystatin-perforated patch, whole cell recordings were obtained from bipolar cells in a retinal slice preparation of larval tiger salamander. in the presence of ba(2+), vol ... | 2000 | 10675784 |

| fate and the biochemical effects of 2,4,6-trinitrotoluene exposure to tiger salamanders (ambystoma tigrinum). | biotransformation, metabolic enzyme profiles, and the glutathione antioxidant system in tiger salamanders (ambystoma tigrinum) from a 14-day exposure to 2,4,6-trinitrotoluene (tnt) in situ were examined. concentrations of parent compound and metabolites were measured in skin, kidney, and liver tissue. in addition, cytochrome p450 (p450) and cytochrome b5 content and their dependent isozyme activities, ethoxyresorufin o-dealkylation, pentoxyresorufin o-dealkylation, and the glutathione antioxidan ... | 2000 | 10831332 |
| mechanics of lung ventilation in a post-metamorphic salamander, ambystoma tigrinum. | the mechanics of lung ventilation in frogs and aquatic salamanders has been well characterized, whereas lung ventilation in terrestrial-phase (post-metamorphic) salamanders has received little attention. we used electromyography (emg), x-ray videography, standard videography and buccal and body cavity pressure measurements to characterize the ventilation mechanics of adult (post-metamorphic) tiger salamanders (ambystoma tigrinum). three results emerged: (i) under terrestrial conditions or when f ... | 2000 | 10683167 |
| relationships between odor-elicited oscillations in the salamander olfactory epithelium and olfactory bulb. | oscillations in neuronal population activity, or the synchronous neuronal spiking that underlies them, are thought to play a functional role in sensory processing in the cns. in the olfactory system, stimulus-induced oscillations are observed both in central processing areas and in the peripheral receptor epithelium. to examine the relationship between these peripheral and central oscillations, we recorded local field potentials simultaneously from the olfactory epithelium and olfactory bulb in ... | 2000 | 10669491 |
| health and rapid economic change in the late twentieth century. | rapidly expanding economies, such as the post-war tiger economies, are associated with increasing health and rapidly contracting economies, such as central and eastern europe in the early 1990s, are associated with declining health. in central and eastern europe health decline in association with economic contraction has been mediated by changes in income distribution and, also, by health-determining aspects of civil society. the nations of central and eastern europe are an example of swift econ ... | 2000 | 10972426 |
| differential modulation of rod and cone calcium currents in tiger salamander retina by d2 dopamine receptors and camp. | synaptic transmission from vertebrate photoreceptors involves activation of l-type calcium currents (ica). dopamine is an important circadian neuromodulator in the retina and photoreceptors possess d2 dopamine receptors. we examined modulation of ica by dopamine and camp in retinal slices and isolated cells of larval tiger salamander. results show that dopamine and a d2 agonist, quinpirole, enhanced ica in rods and red-, blue- and uv-sensitive small single cones but inhibited ica in red-sensitiv ... | 2000 | 11029623 |
| polymicrobial tenosynovitis with pasteurella multocida and other gram negative bacilli after a siberian tiger bite. | mammalian bites present a considerable clinical problem because they are often associated with bacterial infections. pasteurella multocida is a microorganism that commonly infects both canine and small feline bites. zoonotic infections developing after large feline bites have been recognised, although their reports are limited. we describe a 35 year old man who was bitten by a siberian tiger and who developed infectious tenosynovitis secondary to p multocida, bergeyella (weeksella) zoohelcum, an ... | 2000 | 11127273 |
| spontaneous discrimination of natural stimuli by chimpanzees (pan troglodytes). | six chimpanzees (pan troglodytes) were presented with pairs of color photographic images of 5 different categories of animals (cat, chimp, gorilla, tiger, fish). the subjects responded to each pair using symbols for "same" and "different." both within- and between-category discriminations were tested, and all chimpanzees classified the image pairs in accordance with the 5 experimenter-defined categories under conditions of nondifferential reinforcement. although previous studies have demonstrate ... | 2000 | 11149543 |
| birth of siberian tiger (panthera tigris altaica) cubs after transvaginal artificial insemination. | a captive 9-yr-old female siberian tiger (panthera tigris altaica) at the lisbon zoo was treated with equine chorionic gonadotropin followed 80 hr later by human chorionic gonadotropin to stimulate follicular development and ovulation, respectively. forty-one hours after the second hormone administration, the tiger was subjected to transvaginal artificial insemination with diluted fresh semen containing 500 x 10(6) motile spermatozoa obtained from an 8-yr-old male siberian tiger via electroejacu ... | 2000 | 11428407 |
| microsatellite polymorphism and the population structure of the black tiger shrimp (penaeus monodon) in thailand. | genetic variation and differentiation of thai penaeus monodon from five geographic locations (chumphon, trad, phangnga, satun, and trang) were investigated using five microsatellite loci (cupmo18, di25, di27, cscupmo1, and cscupmo2). the number of alleles across the five loci ranged from 19 to 30, and heterozygosities ranged from 0.49 to 0.95. the mean number of alleles and effective number of alleles per locus were 21.0 to 26.6 and 13.1 to 20.4, respectively. the average heterozygosity across a ... | 2000 | 10960123 |

| immunomodulation by dietary beta-1, 3-glucan in the brooders of the black tiger shrimp penaeus monodon. | the present study evaluated the effectiveness of beta-1,3-glucan derived from schizophyllum commune in enhancing shrimp survival as well as haemocyte phagocytosis and superoxide anion production in brooder penaeus monodon. pond-reared p. monodon adults (135 +/- 25 g) stocked in outdoor or indoor tanks were fed either a test diet containing beta-1,3-glucan (2.0 g kg(-1) or a glucan-free control diet for 40 days. their survival was compared. the brooders reared in indoor tanks were analysed at day ... | 2000 | 11016585 |
| clinical toxicology: a tropical australian perspective. | tropical australia has an amazing diversity of venomous fauna, from "the world's most venomous creature," the multi-tentacled (chirodropid) box jellyfish chironex fleckeri, to aggressive spiders whose venom remains to be characterized. all genera of highly venomous australasian elapid snakes are present, except for tiger snakes. most notable is the taipan (oxyuranus scutellatus), with the most efficient "snap-release" biting mechanism of any snake and venom components causing the full constellat ... | 2000 | 10688264 |
| characterisation of different morphological features of black tiger shrimp (penaeus monodon) haemocytes using monoclonal antibodies. | monoclonal antibodies (mabs) specific for penaeus monodon haemocytes were produced by immunising mice with membrane lysates of shrimp haemocytes. four mabs (wsh 6, wsh 7, wsh 8 and wsh 16) were characterised using flow cytometry, light microscopy, laser scanning microscopy, electron microscopy and immunoprecipitation. wsh 6 recognised a carbohydrate determinant on an 85 kda molecule. wsh 7, wsh 8 and wsh 16 recognised 50, 35 and 115 kda molecules, respectively. for all mabs, differences in amoun ... | 2000 | 11016586 |
| degenerative spinal disease in large felids. | degenerative spinal disorders, including intervertebral disc disease and spondylosis, seldom occur in domestic cats. in contrast, a retrospective study of 13 lions (panthera leo), 16 tigers (panthera tigris), 4 leopards (panthera pardis), 1 snow leopard (panthera uncia), and 3 jaguars (panthera onca) from the knoxville zoo that died or were euthanatized from 1976 to 1996 indicated that degenerative spinal disease is an important problem in large nondomestic felids. the medical record, radiograph ... | 2000 | 10884118 |
| the envenomation syndrome caused by the australian red-bellied black snake pseudechis porphyriacus. | the australian elapids inject venom which is characteristic of each species; and which cause characteristic and specific envenomation syndromes in human victims of snakebite. because many of the medically significant australian elapids look similar, when glimpsed in the field by snakebite victims, defining human envenomation syndromes with secure species identification has been a slow process. correlations between securely identified species and the human envenomation syndromes which they produc ... | 2000 | 10858512 |
| the complete sequence of the mitochondrial genome of the crustacean penaeus monodon: are malacostracan crustaceans more closely related to insects than to branchiopods? | the complete sequence of the mitochondrial genome of the giant tiger prawn, penaeus monodon (arthropoda, crustacea, malacostraca), is presented. the gene content and gene order are identical to those observed in drosophila yakuba. the overall at composition is lower than that observed in the known insect mitochondrial genomes, but higher than that observed in the other two crustaceans for which complete mitochondrial sequence is available. analysis of the effect of nucleotide bias on codon compo ... | 2000 | 10833192 |
| recovery of penaeus monodon from functional anaemia after exposure to sublethal concentration of nitrite at different ph levels. | tiger shrimp penaeus monodon (14.79+/-0.19 g) which had been exposed individually to 0.72 mm nitrite at ph 6.8, 8.2 and 9.8 after 3, 6, 12, 24 and 48 h were examined for the water nitrite concentration, hemolymph nitrite, oxyhemocyanin, protein and osmolality levels. same parameters were examined for shrimp depurated in nitrite-free water after 3, 6, 12 and 24 h following 48 h exposure to nitrite. in the nitrite-exposed test, nitrite influx, hemolymph nitrite and osmotic differential (medium osm ... | 2000 | 10930651 |
| pharmacological adrenalectomy with mitotane. | the potential of mitotane (ortho, para'-ddd, commonly used to treat adrenal carcinomas in humans and dogs) was investigated as an alternative to surgical adrenalectomy in birds, salamanders, and lizards. house sparrows (passer domesticus) were injected twice daily with vehicle or one of two doses of mitotane (225 or 450 mg/kg), and basal and stress-induced levels of corticosterone (cort) were measured 3 and 5 days after injections. mitotane reduced basal cort levels to nondetectable and abolishe ... | 2000 | 11042008 |
| [origin of lepidoptera fauna of the southern transural region]. | the butterfly fauna of the southern transural region began mainly through the migration of insects from the urals and kazakhstan, since the end of the cretaceous period to the end of paleogen, the transural region was covered by an epiplatform sea. as this sea was retreating, the first regions of dry land appeared, which had boundaries with kazakhstan and the urals. they were the first to be populated by lepidoptera. during the pleocene and then after the pleistocene cooling events, insects sett ... | 2000 | 11042964 |
