Ontologías Turísticas Geográficas : creación de una ontología sobre rutas turísticas (a Pie o en Bicicleta) por espacios naturales

El turismo es un área en constante crecimiento en la cual, la aparición de las nuevas tecnologías y, fundamentalmente, de Internet, ha tenido un gran impacto en los procedimientos internos de los agentes turísticos y en los métodos de contratación y de búsqueda de información por parte de los usuarios. Por otro lado, la cantidad ingente de información disponible en Internet y el gran desorden existente, provoca la aparición del concepto de Web semántica, una tecnología que dota a las máquinas de un nivel de compresión de la Web suficiente como para hacer de la búsqueda y el acceso a la información una tarea sencilla y natural. Este artículo trata, en primer lugar, de analizar el estado del arte de la Web semántica relacionada con el ámbito del turismo, presentando las ontologías turísticas disponibles en la actualidad para, a continuación, describir el desarrollo de una ontología específica dentro del dominio de las rutas turísticas. Con esta ontología, a través de un ejemplo, se trata de demostrar la utilidad de esta tecnología a la hora de catalogar información relacionada, disponible y dispersa por páginas Web en Internet.

Llengua al límit. Una llengua, dos camins. L'encontre necessari.

En el treball es realitza una transcripció de dos programes de televisió, amb la idea de saber quin és el tipus de llenguatge que usen aquests mitjans per adreçar-se al seu públic. Però seria absurd ignorar altres canals per als quals la llengua és imprescindible. Em refereixo al cinema, sobretot. I malgrat que no es considera un mitjà de comunicació, també és un element importantíssim pel que fa al tractament i transmissió lingüístics. I molts productes del cinema acaben sortint per televisió. La premsa escrita i, com a cas especial, Internet, també hi tenen força a dir.

Isolation and molecular identification of Leishmania chagasi from a bat (Carollia perspicillata) in northeastern Venezuela

This report describes the isolation of a Leishmania chagasi strain from a bat (Carollia perspicillata), and its identification using biological methods and molecular characterization. The parasites were isolated in an artificial culture medium from a blood sample extracted from a bat heart. The isolate was then inoculated into the footpads of Balb/c mice, which subsequently developed a typical nodular leishmanial lesion; the parasites were confirmed as Leishmania by smear and histopathology. Molecular characterization of the parasites was performed by polymerase chain reaction with species-specific primers, kDNA restriction pattern following Hae III endonuclease digestion and dot blot hybridization using a kDNA probe. This report demonstrates that bats can be hosts for L. chagasi species and suggests the need for studies to determine whether they may be involved in foci of visceral leishmaniasis.

In vitro anti-microbial activity of the Cuban medicinal plants Simarouba glauca DC, Melaleuca leucadendron L and Artemisia absinthium L

In the present study, an extensive in vitro antimicrobial profiling was performed for three medicinal plants grown in Cuba, namely Simarouba glauca, Melaleuca leucadendron and Artemisia absinthium. Ethanol extracts were tested for their antiprotozoal potential against Trypanosoma b. brucei, Trypanosoma cruzi, Leishmania infantum and Plasmodium falciparum. Antifungal activities were evaluated against Microsporum canis and Candida albicans whereas Escherichia coli and Staphylococcus aureus were used as test organisms for antibacterial activity. Cytotoxicity was assessed against human MRC-5 cells. Only M. leucadendron extract showed selective activity against microorganisms tested. Although S. glauca exhibited strong activity against all protozoa, it must be considered non-specific. The value of integrated evaluation of extracts with particular reference to selectivity is discussed.

Association of Patients' Geographic Origins with Viral Hepatitis Co-infection

To determine if hepatitis C virus seropositivity and active hepatitis B virus infection in HIV-positive patients vary with patients' geographic origins, we studied co-infections in HIV-seropositive adults. Active hepatitis B infection was more prevalent in persons from Africa, and hepatitis C seropositivity was more common in persons from eastern Europe.

A Genome-Wide Association Study of Upper Aerodigestive Tract Cancers Conducted within the INHANCE Consortium

Genome-wide association studies (GWAS) have been successful in identifying common genetic variation involved in susceptibility to etiologically complex disease. We conducted a GWAS to identify common genetic variation involved in susceptibility to upper aero-digestive tract (UADT) cancers. Genome-wide genotyping was carried out using the Illumina HumanHap300 beadchips in 2,091 UADT cancer cases and 3,513 controls from two large European multi-centre UADT cancer studies, as well as 4,821 generic controls. The 19 top-ranked variants were investigated further in an additional 6,514 UADT cancer cases and 7,892 controls of European descent from an additional 13 UADT cancer studies participating in the INHANCE consortium. Five common variants presented evidence for significant association in the combined analysis (p≤5×10−7). Two novel variants were identified, a 4q21 variant (rs1494961, p = 1×10−8) located near DNA repair related genes HEL308 and FAM175A (or Abraxas) and a 12q24 variant (rs4767364, p = 2×10−8) located in an extended linkage disequilibrium region that contains multiple genes including the aldehyde dehydrogenase 2 (ALDH2) gene. Three remaining variants are located in the ADH gene cluster and were identified previously in a candidate gene study involving some of these samples. The association between these three variants and UADT cancers was independently replicated in 5,092 UADT cancer cases and 6,794 controls non-overlapping samples presented here (rs1573496-ADH7, p = 5×10−8; rs1229984-ADH1B, p = 7×10−9; and rs698-ADH1C, p = 0.02). These results implicate two variants at 4q21 and 12q24 and further highlight three ADH variants in UADT cancer susceptibility.

Use of the internet as a source of health information by Spanish adolescents

The Internet is a fundamental part of the daily life of adolescents, they consider it as a safe and confidential source of information on health matters. The aims is to describe the experience of Spanish adolescents searching for health information on the Internet. Methods A cross-sectional study of 811 school-age adolescents in Granada was carried out. An adapted and piloted questionnaire was used which was controlled by trained personnel. Sociodemographic and health variables were included together with those concerning the conditions governing access to and use of information and communication technologies (ICT). Results 811 adolescents were surveyed (99.38% response rate), mean age was 17 years old. Of these, 88% used the Internet; 57.5% used it on a daily or weekly basis and 38.7% used it occasionally. Nearly half the sample group (55.7%) stated that they used the Internet to search for health-related information. The main problems reported in the search for e-health were the ignorance of good web pages (54.8%) and the lack of confidence or search skills (23.2%). Conclusions In conclusion, it seems plausible to claim that websites designed and managed by health services should have a predominant position among interventions specifically addressed to young people.

Metodologia per a la generació de consens social en el desplegament d'infraestructures de telefonia mòbil

Aquest document de treball es centra específicament en el desenvolupament de la infraestructura de telefonia mòbil a Catalunya com a exemple de tecnologia amb profundes implicacions socials. Esdevé un intent inicial de definir les principals línies de recerca en aquest tema. El projecte que el sosté és emmarcat en el programa de recerca Negrisc, centrat a examinar la negociació del risc en les tecnologies de la informació i de la comunicació. Parteix d'una aproximació que reconeix la natura multidisciplinària del risc i que, per tant, exigeix una aproximació interdisciplinària al seu estudi i a la gestió subsegüent. Aquesta perspectiva emfatitza la necessitat d'integrar els punts de vista dels diferents stakeholders, incloent-hi el públic, en la gestió d'una tecnologia socialment controvertida. Aquest és un pas necessari per a permetre la generació d'algun tipus de consens en el cas del desenvolupament de la infraestructura de telefonia mòbil a Catalunya.

Air pollution exposure during pregnancy and reduced birth size: a prospective birth cohort study in Valencia, Spain

Background Maternal exposure to air pollution has been related to fetal growth in a number of recent scientific studies. The objective of this study was to assess the association between exposure to air pollution during pregnancy and anthropometric measures at birth in a cohort in Valencia, Spain. Methods Seven hundred and eighty-five pregnant women and their singleton newborns participated in the study. Exposure to ambient nitrogen dioxide (NO2) was estimated by means of land use regression. NO2 spatial estimations were adjusted to correspond to relevant pregnancy periods (whole pregnancy and trimesters) for each woman. Outcome variables were birth weight, length, and head circumference (HC), along with being small for gestational age (SGA). The association between exposure to residential outdoor NO2 and outcomes was assessed controlling for potential confounders and examining the shape of the relationship using generalized additive models (GAM). Results For continuous anthropometric measures, GAM indicated a change in slope at NO2 concentrations of around 40 μg/m3. NO2 exposure >40 μg/m3 during the first trimester was associated with a change in birth length of -0.27 cm (95% CI: -0.51 to -0.03) and with a change in birth weight of -40.3 grams (-96.3 to 15.6); the same exposure throughout the whole pregnancy was associated with a change in birth HC of -0.17 cm (-0.34 to -0.003). The shape of the relation was seen to be roughly linear for the risk of being SGA. A 10 μg/m3 increase in NO2 during the second trimester was associated with being SGA-weight, odds ratio (OR): 1.37 (1.01-1.85). For SGA-length the estimate for the same comparison was OR: 1.42 (0.89-2.25). Conclusions Prenatal exposure to traffic-related air pollution may reduce fetal growth. Findings from this study provide further evidence of the need for developing strategies to reduce air pollution in order to prevent risks to fetal health and development.

Increased neurotransmitter release at the neuromuscular junction in a mouse model of polyglutamine disease.

In Huntington's disease (HD), the expansion of polyglutamine (polyQ) repeats at the N terminus of the ubiquitous protein huntingtin (htt) leads to neurodegeneration in specific brain areas. Neurons degenerating in HD develop synaptic dysfunctions. However, it is unknown whether mutant htt impacts synaptic function in general. To investigate that, we have focused on the nerve terminals of motor neurons that typically do not degenerate in HD. Here, we have studied synaptic transmission at the neuromuscular junction of transgenic mice expressing a mutant form of htt (R6/1 mice). We have found that the size and frequency of miniature endplate potentials are similar in R6/1 and control mice. In contrast, the amplitude of evoked endplate potentials in R6/1 mice is increased compared to controls. Consistent with a presynaptic increase of release probability, synaptic depression under high-frequency stimulation is higher in R6/1 mice. In addition, no changes were detected in the size and dynamics of the recycling synaptic vesicle pool. Moreover, we have found increased amounts of the synaptic vesicle proteins synaptobrevin 1,2/VAMP 1,2 and cysteine string protein-α, and the SNARE protein SNAP-25, concomitant with normal levels of other synaptic vesicle markers. Our results reveal that the transgenic expression of a mutant form of htt leads to an unexpected gain of synaptic function. That phenotype is likely not secondary to neurodegeneration and might be due to a primary deregulation in synaptic protein levels. Our findings could be relevant to understand synaptic toxic effects of proteins with abnormal polyQ repeats.

Disseny d'un cronòmetre i d'un freqüencímetre integrats en un NIOS controlats sobre μClinux

El projecte que es presenta permet analitzar els avantatges i inconvenients d’una programació orientada a hardware i d’una programació orientada a software a partir del desenvolupament de dos dissenys, un cronòmetre i un freqüencímetre en cadascun dels modes de programació. Donat que en les dues aplicacions es requereix alta precisió de temps (μs) i flexibilitat en el control, la solució final que es proposa és un disseny “mixt” amb dos mòduls hardware específics (cronòmetre i freqüencímetre) integrats en un NIOS/CPU sobre una FPGA. Els dos mòduls es controlen per software sobre un sistema Linux empotrat (μCLinux).
