canary in a coal mine: does the plastic surgery market predict the american economy?economic tools have been used in the past to predict the trends in plastic surgery procedures. since 1992, u.s. cosmetic surgery volumes have increased overall, but the exact relationship between economic downturns and procedural volumes remains elusive. if an economic predicting role can be established from plastic surgery indicators, this could prove to be a very powerful tool.201020679849
identification and characterization of uncoupling protein in heart and muscle mitochondria of canary birds.an uncoupling protein (cucp) was identified in heart and skeletal muscle mitochondria of canary birds. cucp was immunodetected using polyclonal antibodies raised against murine ucp2. its molecular mass was similar to those of mammalian ucps (32 kda). the activity of cucp was stimulated by palmitic acid (pa) and inhibited by gtp mainly in state 3 respiration. additions of pa augmented state 4 respiration and lowered the adp/o ratio. thus, the activity of cucp diverted energy from oxidative phosph ...201020686918
ciguatera fish poisoning on the west africa coast: an emerging risk in the canary islands (spain).ciguatera fish poisoning (cfp) is endemic in certain tropical and subtropical regions of the world. cfp had not been described on the west africa coast until a 2004 outbreak in the canary islands. in 2008-2009, two additional outbreaks of ciguatera occurred. individuals afflicted had consumed lesser amberjack (seriola rivoliana) captured from nearby waters. caribbean ciguatoxin-1 (c-ctx-1) was confirmed in fish samples by lc-ms/ms. ciguatoxic fish in this region may pose a new health risk for th ...201020692274
non-nutrient causes of low-grade, systemic inflammation: support for a 'canary in the mineshaft' view of obesity in chronic disease.a form of low-grade, systemic inflammation ('metaflammation') is linked to many types of chronic disease. initially, this was thought to be causally related to weight gain and obesity and a possible explanation of the link between obesity and disease. however, several lifestyle-related inducers of such inflammation, some of which are associated with obesity, but some of which are not, have now been identified. the most common of these have been nutritive related, suggesting that there could stil ...201120701689
influence of the cultivar on the organic acid and sugar composition of potatoes.citric, malic, tartaric, oxalic, ascorbic, aconitic and fumaric acids, and sucrose, fructose and glucose, were determined in ten potato cultivars (azucena negra, bonita, bonita negra, borralla, colorada de baga, mora, negra, palmera lagarteada, peluca blanca and terrenta) from the canary islands in order to differentiate them. the influence of the production zone was also considered.201020718025

whole-genome characterization of a novel polyomavirus detected in fatally diseased canary birds.polyomaviruses of birds are aetiological agents of acute inflammatory diseases in non-immunocompromised hosts, which is in contrast to mammalian polyomaviruses. vp4, an additional structural protein encoded by the viral genomes of the known avian polyomaviruses, has been suggested to contribute to pathogenicity through loss of cells following induction of apoptosis. four distinct bird polyomaviruses have been identified so far, which infect crows, finches, geese and parrots. using broad-spectrum ...201020797969
evolutionary diversification of the genus theba (gastropoda: helicidae) in space and time: a land snail conquering islands and continents.among oceanic islands, the canary islands offer exceptional opportunities for studying speciation processes due to their habitat diversity and well documented geological history. based on a combined coi+its1 data set for more than 140 specimens, we studied the diversification of the land snail genus theba on the canary islands and adjacent african and european continental areas. phylogenetic analyses resulted in the recognition of 18 genetically distinct clades including at least three new speci ...201020800098
dietary intake of aluminum in a spanish population (canary islands).the aim of this study was to analyze the aluminum content in foods and beverages most commonly consumed by the canary island population to determine the dietary intake of this metal throughout the canary islands as a whole and in each of the seven islands (gran canaria, lanzarote, fuerteventura, tenerife, la palma, la gomera, and el hierro). four hundred and forty samples were analyzed by icp-oes. estimated total intake of aluminum for the canary population was 10.171 mg/day, slightly higher tha ...201020809646
hormonal acceleration of song development illuminates motor control mechanism in canaries.in songbirds, the ontogeny of singing behavior shows strong parallels with human speech learning. as in humans, development of learned vocal behavior requires exposure to an acoustic model of species-typical vocalizations, and, subsequently, a sensorimotor practice period after which the vocalization is produced in a stereotyped manner. this requires mastering motor instructions driving the vocal organ and the respiratory system. recently, it was shown that, in the case of canaries (serinus cana ...201020812319
genetics of flavonoid, carotenoid, and chlorophyll pigments in melon fruit rinds.external color has profound effects on acceptability of agricultural products by consumers. carotenoids and chlorophylls are known to be the major pigments of melon (cucumis melo l.) rinds. flavonoids (especially chalcones and anthocyanins) are also prominent in other fruits but have not been reported to occur in melons fruit. we analyzed the pigments accumulating in rinds of different melon genotypes during fruit development. we found that melon rind color is based on different combinations of ...201020815398

opposite poles: a comparison between two spanish regions in health-related quality of life, with implications for health policy.although health is one of the main determinants of the welfare of societies, few studies have evaluated health related quality of life in representative samples of the population of a region or a country. our aim is to describe the health-related quality of life of the inhabitants of two quite different spanish regions (canary islands and catalonia) and to compare the prevalence of health problems between age-sex groups.201020868523
healthy and unhealthy migrant effect on the mortality of immigrants from wealthy countries residing in spain.this study attempts to identify the possible existence of a healthy migrant effect and an unhealthy migrant effect on the mortality of immigrants from wealthy countries who move to spain. immigrants aged 35-64 years from france, germany, great britain and 16 other wealthy oecd countries who resided in spain were compared with respect to: (1) mortality from cancer, cardiovascular disease, and all other diseases and (2) employment status, duration of residence, and educational level, in two geogra ...201020878542
genetic differentiation of the house mouse around the mediterranean basin: matrilineal footprints of early and late colonization.the molecular signatures of the recent expansion of the western house mouse, mus musculus domesticus, around the mediterranean basin are investigated through the study of mitochondrial d-loop polymorphism on a 1313 individual dataset. when reducing the complexity of the matrilineal network to a series of haplogroups (hgs), our main results indicate that: (i) several hgs are recognized which seem to have almost simultaneously diverged from each other, confirming a recent expansion for the whole s ...201020880891
disentangling ancient interactions: a new extinct passerine provides insights on character displacement among extinct and extant island finches.evolutionary studies of insular biotas are based mainly on extant taxa, although such biotas represent artificial subsets of original faunas because of human-caused extinctions of indigenous species augmented by introduced exotic taxa. this makes it difficult to obtain a full understanding of the history of ecological interactions between extant sympatric species. morphological bill variation of fringilla coelebs and f. teydea (common and blue chaffinches) has been previously studied in the nort ...201020886036
the role of wild rodents in the transmission of trypanosoma evansi infection in an endemic area of the canary islands (spain).trypanosoma evansi was diagnosed for the first time in camels in the canary islands in 1997. several sanitary measures including treatment of infected animals were taken; however, nowadays a little area is still infected. in order to determine possible reservoirs 138 wild rodents were trapped, 64 of them in the infected farms and the remaining 74 in other areas. the captured species were rattus rattus (24), rattus norvegicus (69) and mus musculus domesticus (45). serological (catt/t. evansi), pa ...201020888126
the canary in the coalmine: the sensitivity of mesolimbic dopamine to environmental adversity during development.the hypothalamic-pituitary-adrenal axis has been the focus of extensive research with regard to the phenotypic plasticity this system shows in response to environmental influences on mammalian development. this review proposes that the mesolimbic dopamine system is similarly reactive to indicators of environmental adversity during development. physical, physiological, and toxicological stressors encountered during perinatal development have been routinely demonstrated to affect dopamine neurophy ...201020888857
mitochondrial dna introgression in the european abalone haliotis tuberculata tuberculata: evidence for experimental mtdna paternal inheritance and a natural hybrid sequence.two subspecies of the european abalone have been morphologically recognized: haliotis tuberculata tuberculata, present in the north atlantic, and haliotis tuberculata coccinea, present in the canary islands. among the different nuclear markers used to differentiate these two subspecies, the sperm lysin gene was the most reliable, leading to a 2.2% divergence. concerning the subunit i of the mitochondrial cytochrome oxydase gene (coi), we observed a difference of 3.3% between the two subspecies. ...201020938796
effect of forest clear-cutting on subtropical bryophyte communities in waterfalls, on dripping walls, and along streams.forested freshwater ecosystems worldwide are threatened by a number of anthropogenic disturbances, such as water pollution and canalization. transient or permanent deforestation can also be a serious threat to organisms in forested watersheds, but its effects on different types of freshwater systems has been little studied. we investigated lotic bryophyte communities on rock and soil in subtropical cloud laurel forests on la gomera island in the canary islands, spain, and asked whether the respo ...201020945765
favorable fragmentation: river reservoirs can impede downstream expansion of riparian weeds.river valleys represent biologically rich corridors characterized by natural disturbances that create moist and barren sites suitable for colonization by native riparian plants, and also by weeds. dams and reservoirs interrupt the longitudinal corridors and we hypothesized that this could restrict downstream weed expansion. to consider this "reservoir impediment" hypothesis we assessed the occurrences and abundances of weeds along a 315-km river valley corridor that commenced with an unimpounded ...201020945766
applicability of microwave-assisted extraction combined with lc-ms/ms in the evaluation of booster biocide levels in harbour sediments.a new sample treatment method for the determination of four common booster biocides (diuron, tcmtb, irgarol 1051 and dichlofluanid) in harbour sediment samples has been developed that uses liquid chromatography-tandem mass spectrometry (lc-ms/ms) after microwave-assisted extraction, followed by clean-up and a solid phase extraction preconcentration step (mae-spe). the effects of different variables on mae-spe were studied. the recoveries obtained were greater than 75%, and the relative standard ...201020947123
prevalence of neutralizing antibodies to west nile virus in eleonora's falcons in the canary islands.birds are the major amplifying host for west nile virus (wnv), a flavivirus that may affect humans and transmitted by bloodsucking vectors. eleonora's falcons (falco eleonorae) migrate to the canary islands annually from wnv-endemic regions. to investigate the possible role of eleonora's falcons in the circulation of wnv, we measured wnv-specific antibodies in 81 falcons captured in 2006. none of the nestlings but 14.8% of the adults had wnv-neutralizing antibodies. rt-pcr did not detect flavivi ...201020966288

[social perception of the spanish law for young offenders].the implementation of the law 5/2000 for the regulation of criminal responsibility for minors has led to a change in interventions in cases of juvenile offenders. this law promotes the educational and rehabilitative aims of the measures imposed. however, the focus of the media on the most serious cases has generated considerable alarm in society in general. the aim of this study is to determine the social perception of law 5/2000. for this purpose, a sample of 936 people from the autonomous regi ...201021044525
response to intervention (rti) model: a promising alternative for identifying students with learning disabilities?until recently, in the united states, the traditional way to identify students with specific learning disabilities (sld) was through the discrepancy model where student iqs were compared to their level of achievement. however, educators and researchers alike have questioned this model as a means to define and identify students with sld. the 2004 reauthorization of the individuals with disabilities education improvement act (ideia) includes the use of response to intervention (rti) as possible al ...201021044534
implementation of response to intervention (rti) model in spain: an example of a collaboration between canarian universities and the department of education of the canary islands.the purpose of this study was to examine the effectiveness of second tier intervention at-risk readers within the context of a response to intervention approach. the study was conducted in the canary islands (spain), directed by research team ¨dificultades de aprendizaje, psicolingüística y nuevas tecnologías¨ (dea&nt) from university of la laguna, and supported by the government of the canary islands. a sample of 1.123 spanish children from fourteen schools districts were given the spanish adap ...201021044535
closed-loop bird-computer interactions: a new method to study the role of bird calls.in the field of songbird research, many studies have shown the role of male songs in territorial defense and courtship. calling, another important acoustic communication signal, has received much less attention, however, because calls are assumed to contain less information about the emitter than songs do. birdcall repertoire is diverse, and the role of calls has been found to be significant in the area of social interaction, for example, in pair, family, and group cohesion. however, standard me ...201021052754
health related quality of life of canary island citizens.the aim of the study was to describe the health-related quality of life of canarian population using information from the canary island health survey and three observational studies developed in the canary islands.201021054832
optical seeing-mechanism of formation of thin turbulent laminae in the atmosphere.data from balloon soundings taken at sites in the canary islands, france, and chile are used to show that hydrodynamic instability, perhaps engendered by the propagation of buoyancy (gravity) or other waves, leads to the formation of thin, turbulent laminae, or "seeing layers." these seeing layers occur almost invariably in pairs and exhibit large values for the temperature-structure coefficient c(t)(2) because they form where the gradient of temperature is particularly steep. the refractive-ind ...199521060368
