| murine typhus with renal involvement in canary islands, spain. | murine typhus and "murine-typhus-like" disease are reemerging infectious diseases. in canary islands (spain), a rather distinct clinical pattern characterized by higher incidence of complications, especially renal damage (including acute failure and urinalysis abnormalities), is apparent and highly suggestive. it could be related to different strains of rickettsia typhi or other cross-reactive species. | 2004 | 15200874 |
| polypharmacy in psychiatric practice in the canary islands. | polypharmacy with psychoactive drugs is an increasingly common and debatable contemporary practice in clinical psychiatry based more upon experience than evidence. the objective of this study was to evaluate the prevalence and conditioners of polypharmacy in psychiatric patients. | 2004 | 15236661 |
| inhibition of plasma butyrylcholinesterase activity in the lizard gallotia galloti palmae by pesticides: a field study. | a field study was performed to evaluate the effect of exposure to organophosphorus (op) and carbamate (cb) pesticides on the lizard gallotia galloti palmae. butyrylcholinesterase (bche) activity was measured in the plasma of 420 lizards collected from agricultural and reference areas on the island of la palma (canary islands, spain) in two sampling periods. exposure to cholinesterase-inhibiting pesticides was evaluated by a statistical criterion based on a threshold value (two standard deviation ... | 2004 | 15325464 |
| allozyme variation and structure of the canarian endemic palm tree phoenix canariensis (arecaceae): implications for conservation. | electrophoretic analysis of 18 allozyme loci was used to estimate the levels and structuring of genetic variation within and among natural populations of the protected endemic palm species from the canary islands (phoenix canariensis) to evaluate its genetic relationship with the widespread congener p. dactylifera, and to assess comparatively the genetic variation in the populations where the two species coexist with morphologically intermediate plants (mixed populations). our survey revealed th ... | 2004 | 15241448 |
| european starling chicks benefit from high yolk testosterone levels during a drought year. | avian egg yolk contains androgenic hormones, such as testosterone, of maternal origin. experimental elevation of yolk testosterone levels enhances growth of canary chicks. success in sibling competition, due to increased begging, is presumed to underlie this growth enhancement, because canary hatchlings from testosterone-treated eggs beg longer in response to vibrational stimuli than controls. furthermore, experimental elevation of both yolk androstenedione and testosterone increased chick growt ... | 2004 | 15256308 |
| catecholaminergic inputs to aromatase cells in the canary auditory forebrain. | the caudomedial nidopallium in songbirds is a specialized forebrain auditory region involved in the processing of species-typical vocalizations. it receives a prominent catecholaminergic projection with many fibers forming basket-like structures around non-immunoreactive cells. we investigated in male canaries the anatomical relationship between tyrosine hydroxylase and cells immunoreactive for the steroid metabolizing enzyme, aromatase, in the caudomedial nidopallium using double-label immunocy ... | 2004 | 15257136 |
| strong phylogeographic relationships among three goat breeds from the canary islands. | we partially sequenced the mitochondrial d-loop region in 47 individuals from eleven spanish and foreign goat breeds. phylogenetic analysis of these sequences allowed us to identify a particular d-loop haplotype shared by individuals from the palmera, majorera and tinerfeña canarian breeds. genotyping of 281 goats from 17 different breeds by pcr-hpall rflp evidenced that the geographical distribution of this haplotype is restricted to the canary islands. this ancestral mitochondrial haplotype mi ... | 2004 | 15354570 |
| modulation by steroid hormones of a "sexy" acoustic signal in an oscine species, the common canary serinus canaria. | the respective influence of testosterone and estradiol on the structure of the common canary serinus canaria song was studied by experimentally controlling blood levels of steroid hormones in males and analyzing the consequent effects on acoustic parameters. a detailed acoustic analysis of the songs produced before and after hormonal manipulation revealed that testosterone and estradiol seem to control distinct song parameters independently. the presence of receptors for testosterone and estradi ... | 2004 | 15258651 |
| bioacoustics of human whistled languages: an alternative approach to the cognitive processes of language. | whistled languages are a valuable heritage of human culture. this paper gives a first survey about a new multidisciplinary approach to these languages. previous studies on whistled equivalents of languages have already documented that they can provide significant information about the role of rhythm and melody in language. to substantiate this, most whistles are represented by modulations of frequency, centered around 2000 hz (+/- 1000 hz) and often reach a loudness of about 130 db (measured at ... | 2004 | 15258658 |
| finite-frequency tomography reveals a variety of plumes in the mantle. | we present tomographic evidence for the existence of deep-mantle thermal convection plumes. p-wave velocity images show at least six well-resolved plumes that extend into the lowermost mantle: ascension, azores, canary, easter, samoa, and tahiti. other less well-resolved plumes, including hawaii, may also reach the lowermost mantle. we also see several plumes that are mostly confined to the upper mantle, suggesting that convection may be partially separated into two depth regimes. all of the obs ... | 2004 | 14657505 |
| ancient mtdna analysis and the origin of the guanches. | the prehistoric colonisation of the canary islands by the guanches (native canarians) woke up great expectation about their origin, since the europeans conquest of the archipelago. here, we report mitochondrial dna analysis (hvri sequences and rflps) of aborigine remains around 1000 years old. the sequences retrieved show that the guanches possessed u6b1 lineages that are in the present day canarian population, but not in africans. in turn, u6b, the phylogenetically closest ancestor found in afr ... | 2004 | 14508507 |
| content of aliphatic hydrocarbons in limpets as a new way for classification of species using artificial neural networks. | it is demonstrated that biological species like limpets can be classified according to their level of n-alkanes when artificial neural networks are applied. marine intertidal and subtidal limpets of the canary islands (spain), patella piperata, patella candei crenata and patella ulyssiponensis aspera were selected as bioindicator organisms. samples were collected at four stations on the coasts of fuerteventura. concentration of n-alkanes in the soft tissues of the limpets has been determined by ... | 2004 | 14664834 |
| multiple disturbances accelerate invasion of reed canary grass (phalaris arundinaceal.) in a mesocosm study. | disturbances that intensify with agriculture and/or urban development are thought to promote the spread of invasive plants, such as the clonal perennial reed canary grass (phalaris arundinaceal). to test this relationship and interactions among disturbances, we subjected wet prairie assemblages within 1.1 m(2) mesocosms to invasion by phalaris and addition of nutrients, sediments, and flooding. species richness decreased with the application of sediments and/or flooding of 4 consecutive weeks or ... | 2004 | 14669006 |
| phytophotolysis of hexahydro-1,3,5-trinitro-1,3,5-triazine (rdx) in leaves of reed canary grass. | hexahydro-1,3,5-trinitro-1,3,5-triazine (rdx) was degraded in reed canary grass leaves exposed to simulated sunlight to primary products nitrous oxide and 4-nitro-2,4-diazabutanal. this is the first time that 4-nitro-2,4-diazabutanal, a potentially toxic degradate, has been measured in plant tissues following phytotransformation of rdx. these compounds, along with nitrite and formaldehyde, were also detected in aqueous rdx systems exposed to the same simulated sunlight. results showed that the i ... | 2004 | 14740749 |
| trypanosoma avium: experimental transmission from black flies to canaries. | trypanosomes identified as trypanosoma avium were found in the ornithophilic black flies ( eusimulium latipes) attacking buzzard nestlings ( buteo buteo). parasites formed plugs and rosettes in the hindgut of the vector and were attached on the cuticular lining of the black fly anterior intestine (ileum) by hemidesmosome-like plaques. hindgut stages from infected black flies were experimentally transmitted into canaries ( serinus canaria) by ingestion of vectors and by contamination of host conj ... | 2004 | 14652745 |

| influence of seed size and seed nature on recruitment in the polymorphic harvester ant messor barbarus. | in the polymorphic harvester ant messor barbarus, the colony modulates response during foraging according to seed characteristics. the easiness of picking up small seeds (oat fragments or canary seeds) shortens the time lapse between food discovery and the return of scouts to the nest, favouring the onset of recruitment and higher mobilisation rates than bigger seeds (whole oat). however, size is not the only criterion, as canary seeds are preferred among small ones. a modulation of the trail la ... | 2005 | 16140470 |
| changes on bone mineral density after adjuvant treatment in women with non-metastatic breast cancer. | . adjuvant therapies have prolonged survival of non-metastatic breast cancer (nmbc) patients, but they also decrease bone mineral density (bmd). we have analyzed the effects of chemotherapy, hormone therapy with tamoxifen or both, on bmd of women with nmbc. | 2005 | 16184462 |
| parasites affect song complexity and neural development in a songbird. | there is now considerable evidence that female choice drives the evolution of song complexity in many songbird species. however, the underlying basis for such choice remains controversial. the developmental stress hypothesis suggests that early developmental conditions can mediate adult song complexity by perturbing investment in the underlying brain nuclei during their initial growth. here, we show that adult male canaries (serinus canaria), infected with malaria (plasmodium relictum) as juveni ... | 2005 | 16191614 |
