Cáncer en los primeros 18 meses de vida
2020
Resumen: Introducción: La enfermedad oncohematológica continúa siendo la primera causa de mortalidad no traumática en la infancia y una importante causa de morbilidad. El paciente menor de 18 meses presenta particularidades clínicas, diagnósticas y terapéuticas que es interesante conocer por todo pediatra, con el fin de lograr una mayor supervivencia y una menor comorbilidad a lo largo de su vida. Material y métodos: Estudio descriptivo retrospectivo de variables clínicas, diagnósticas y terapéuticas en pacientes menores de 18 meses diagnosticados de enfermedad oncohematológica que reciben quimioterapia en una unidad de oncología pediátrica entre enero 2007 y agosto 2019. Resultados: Setent…
Social Desirability Bias among Prejudice Instruments : An Integrated Threat
2019
A considerable amount of research has examined the extent to which members of dominant cultures perceive minority groups as threatening their way of life. While various instruments measure these perceptions of threat, few researchers have empirically analysed the statistical properties of these scales. Specifically, studies have not adequately explored social desirability of threat scales. The current study investigates the extent to which one set of threat scales is internally consistent or reliable (González et al., 2008), and explores social desirability within the González et al. (2008) integrated threat instruments by comparing self-reports to other reports (intimate other and friend r…
Up-to-date report on the distribution ofHelianthemum lippii(Cistaceae) in Italy
2015
An up-to-date report on the distribution of Helianthemum lippii in Italy is provided also on the basis of the findings by Lojacono-Pojero in 1889 who reported the existence of a relic population in Sicily (southern Italy), which is now thought to be extinct because of human disturbance. Field excursions permitted to confirm the locus classicus reported by Lojacono-Pojero as the other Sicilian localities that have been reported more recently. Based on a careful analysis of the literature the presence of H. lippii is currently excluded in Calabria and Apulia. The main causes that threaten the habitat of H. lippii in Sicily are pointed out according to IUCN Threats Classification Scheme.
Quantifying the Indicator Power of an Indicator Species
2009
Biodiversity indicator species are needed for classifying biotopes and sites for conservation, and a number of methods have been developed for determining indicator species for this purpose. Nevertheless, in addition to site classification, there is sometimes a need to define an indicator species that indicates the occurrence of another species. For example, when a species of interest (target species) is difficult to detect or identify, a reliable indicator species can function as a tool that saves time and money. We derived a method that provides a quantitative measure of the indicator power (IP) of an indicator species for the target species or any species assemblage. We calculated the me…
Identifying potential areas of expansion for the endangered brown bear (Ursus arctos) population in the cantabrian mountains (NW Spain)
2019
Many large carnivore populations are expanding into human-modified landscapes and the subsequent increase in coexistence between humans and large carnivores may intensify various types of conflicts. A proactive management approach is critical to successful mitigation of such conflicts. The Cantabrian Mountains in Northern Spain are home to the last remaining native brown bear (Ursus arctos) population of the Iberian Peninsula, which is also amongst the most severely threatened European populations, with an important core group residing in the province of Asturias. There are indications that this small population is demographically expanding its range. The identification of the potential are…
Izvairīšanās no lingvistiski-pragmatiskās kļūdas angļu valodā
2019
Šī bakalaura darba mērķis ir analizēt, vai lingvistiskais netiešums var izraisīt lingvistiski-pragmatisko kļūdu, un kādus lingvistiskos instrumentus var izmantot, lai izvairītos no konflikta. Lai analizētu politisko interviju plašsaziņas līdzekļos, tiek izmantota kvalitatīva pētījuma metode, kuras mērķis ir izpētīt, kā atrisināt lingvistisko netiešumu sarunā, kā atšķirt pateikto no tā, ko vēlas pateikt, kā arī to, kā izvairīties no lingvistiski–pragmatiskās kļūdas neskaidras valodas dēļ. Rezultāti liecina, ka kritērijs spējai pieņemt mijiedarbību ir atkarīgs no tā, cik lielā mērā tā var būt kaitīga sarunu partneriem, jo ikvienam sarunas partnerim pirmām kārtām rūp viņa personīgais tēls. Līd…
New insights into the gut microbiome in loggerhead sea turtles Caretta caretta stranded on the Mediterranean coast
2019
Caretta caretta is the most common sea turtle species in the Mediterranean Sea. The species is threatened by anthropomorphic activity that causes thousands of deaths and hundreds of strandings along the Mediterranean coast. Stranded turtles are often cared for in rehabilitation centres until they recover or die. The objective of this study was to characterize the gut microbiome of nine sea turtles stranded along the Sicilian coast of the Mediterranean Sea using high-throughput sequencing analysis targeting V3–V4 regions of the bacterial 16S rRNA gene. Stool samples were collected from eight specimens hosted in the recovery centre after a few days of hospitalization (under 7) and from one ho…
Assessing Effects of Temperature Change on Four Limonium Species from Threatened Mediterranean Salt-Affected Habitats
2018
[EN] Evaluation of tolerance to temperatures in the germination stage is an important tool to foresee the possible effect of global warming. Moreover, establishing germination protocols for endemic and threatened species is most interesting for restoration and management plans that focus on habitat conservation. Seed germination was analysed in four species of the genus Limonium (L. virgatum, L. narbonense, L. girardianum and L. santapolense) growing in two saline habitats on the eastern coast of the Iberian Peninsula. The study aim was to compare responses of seed germination to different temperature regimes. Seeds were collected in two protected areas, `L¿Albufera de Valencia¿ (province o…
Psychometric properties of the questionnaire on threat perception of chronic illnesses in pediatric patients*
2020
Objetivo: o objetivo do estudo foi avaliar as propriedades psicometricas do Questionario de Percepcao de Doencas Versao Breve em uma amostra de adolescentes com condicoes endocrinas ou pneumologicas cronicas. Analisar a dimensionalidade e reduzir a escala elaborando baremas por sexo e diagnostico medico. Metodo: avaliamos 510 pacientes com idades entre 9 e 16 anos usando o Questionario de Percepcao de Doencas Versao Breve e a Escala Hospitalar de Ansiedade e Depressao. Foram realizados testes de confiabilidade, validade do construto, validade de criterio e comparacao de medias segundo o diagnostico e as variaveis sociodemograficas. As analises de confiabilidade e validade mostraram propried…
Ten principles for conservation translocations of threatened wood-inhabiting fungi
2020
Abstract Unlike for many other organism groups, conservation translocations of fungi are still rare. Encouraged by recent successful translocations, there is a growing interest in applying this conservation tool to threatened wood-inhabiting fungi. When combined with other conservation or restoration measures, translocation can be an effective measure for preventing further population decline in the short term, and species extinctions in the long term. Translocations can be appropriate for rare and specialist fungal species that occur as small local populations in isolated patches across fragmented landscapes, where there is a low likelihood of successful dispersal between distant host tree…
