N-(2-Oxo-2H-chromen-3-yl)cyclohexanecarboxamide
Maria J. Matos,Lourdes Santana,Eugenio Uriarte
Acta Crystallographica Section E , 2012, DOI: 10.1107/s1600536812047903
Abstract: In the title compound, C16H17NO3, the coumarin moiety is essentially planar [maximum deviation from the mean plane formed by the C and O atoms of the coumarin = 0.0183 (12) ] and that the cyclohexane ring adopts the usual chair conformation. The dihedral angle between the mean plane of the coumarin residue and the plane of the amide residue (defined as the N, C and O atoms) is 18.9 (2)°. There are two intramolecular hydrogen bonds involving the amide group. In one, the N atom acts as donor to the ketonic O atom and in the other, the amide O atom acts as acceptor of a C—H group of the coumarin. In the crystal, molecules are linked into inversion dimers by pairs of N—H...O contacts and these dimers are linked into pairs by weak C—H...O hydrogen bonds. The combination of these interactions creates a chain of rings which runs parallel to [2-10]. C—H...π and π–π [centroid–centroid distance = 3.8654 (10) ] interactions are also observed.

Stochastic Estimation of Seroprevalence Against Ornithobacterium rhinotracheale and Avian Pneumovirus among Chickens in Argentina
J. Uriarte,K. Suzuki,J. Origlia,D. Gornatti
International Journal of Poultry Science , 2010,
Abstract: The objective of this study was to estimate the true prevalence of seropositive individual chicken against Ornithobacterium rhinotracheale and avian pneumovirus in Argentina, using the Rogan-Gladen estimator in combination with Bayesian inference. Chicken runs existed in 21 and 20 different towns in Buenos Aires and Entre Ríos Provinces in Argentina for Ornithobacterium rhinotracheale and avian pneumovirus seroprevalence, respectively, were studied. Individual-chicken sera were analyzed using a commercial enzyme-linked immunosorbent assay. The 719 (for testing Ornithobacterium rhinotracheale) and 933 (for testing avian pneumovirus) chickens were investigated. The overall true seroprevalence was 62.6% [95% Bayesian Credible Interval (BCI): 37.6-84.5%] and 8.0% (95% BCI: 1.4-18.5%) against Ornithobacterium rhinotracheale and avian pneumovirus, respectively.

Wireless Sensor Network for Environmental Monitoring: Application in a Coffee Factory
J. Valverde,V. Rosello,G. Mujica,J. Portilla,A. Uriarte,T. Riesgo
International Journal of Distributed Sensor Networks , 2012, DOI: 10.1155/2012/638067
Abstract: Wireless sensor networks have been a big promise during the last few years, but a lack of real applications makes difficult the establishment of this technology. In this paper a real monitoring application in an instant coffee factory is presented. This application belongs to the group of environmental solutions based on wireless sensor networks, and it is focused on the impact of the instant coffee production processes in one of the largest instant coffee factories in Europe. The paper includes the entire application scenario, from the hardware of the WSN nodes to the software that will evaluate the impact and will close the loop.
Oral Community Interactions of Filifactor alocis In Vitro

PLOS ONE , 2013, DOI: 10.1371/journal.pone.0076271
Abstract: Filifactor alocis is a gram positive anaerobe that is emerging as an important periodontal pathogen. In the oral cavity F. alocis colonizes polymicrobial biofilm communities; however, little is known regarding the nature of the interactions between F. alocis and other oral biofilm bacteria. Here we investigate the community interactions of two strains of F. alocis with Streptococcus gordonii, Fusobacterium nucleatum, Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans, organisms with differing pathogenic potential in the oral cavity. In an in vitro community development model, S. gordonii was antagonistic to the accumulation of F. alocis into a dual species community. In contrast, F. nucleatum and the type strain of F. alocis formed a synergistic partnership. Accumulation of a low passage isolate of F. alocis was also enhanced by F. nucleatum. In three species communities of S. gordonii, F. nucleatum and F. alocis, the antagonistic effects of S. gordonii superseded the synergistic effects of F. nucleatum toward F. alocis. The interaction between A. actinomycetemcomitans and F. alocis was strain specific and A. actinomycetemcomitans could either stimulate F. alocis accumulation or have no effect depending on the strain. P. gingivalis and F. alocis formed heterotypic communities with the amount of P. gingivalis greater than in the absence of F. alocis. However, while P. gingivalis benefited from the relationship, levels of F. alocis in the dual species community were lower compared to F. alocis alone. The inhibitory effect of P. gingivalis toward F. alocis was dependent, at least partially, on the presence of the Mfa1 fimbrial subunit. In addition, AI-2 production by P. gingivalis helped maintain levels of F. alocis. Collectively, these results show that the pattern of F. alocis colonization will be dictated by the spatial composition of microbial microenvironments, and that the organism may preferentially accumulate at sites rich in F. nucleatum.
Asymmetric Dispersal and Colonization Success of Amazonian Plant-Ants Queens

PLOS ONE , 2011, DOI: 10.1371/journal.pone.0022937
Abstract: Background The dispersal ability of queens is central to understanding ant life-history evolution, and plays a fundamental role in ant population and community dynamics, the maintenance of genetic diversity, and the spread of invasive ants. In tropical ecosystems, species from over 40 genera of ants establish colonies in the stems, hollow thorns, or leaf pouches of specialized plants. However, little is known about the relative dispersal ability of queens competing for access to the same host plants. Methodology/Principal Findings We used empirical data and inverse modeling—a technique developed by plant ecologists to model seed dispersal—to quantify and compare the dispersal kernels of queens from three Amazonian ant species that compete for access to host-plants. We found that the modal colonization distance of queens varied 8-fold, with the generalist ant species (Crematogaster laevis) having a greater modal distance than two specialists (Pheidole minutula, Azteca sp.) that use the same host-plants. However, our results also suggest that queens of Azteca sp. have maximal distances that are four-sixteen times greater than those of its competitors. Conclusions/Significance We found large differences between ant species in both the modal and maximal distance ant queens disperse to find vacant seedlings used to found new colonies. These differences could result from interspecific differences in queen body size, and hence wing musculature, or because queens differ in their ability to identify potential host plants while in flight. Our results provide support for one of the necessary conditions underlying several of the hypothesized mechanisms promoting coexistence in tropical plant-ants. They also suggest that for some ant species limited dispersal capability could pose a significant barrier to the rescue of populations in isolated forest fragments. Finally, we demonstrate that inverse models parameterized with field data are an excellent means of quantifying the dispersal of ant queens.
Itraconazol oral en el tratamiento de un caso de endoftalmitis por candida parapsilosis Oral itraconazole in a Candida parapsilosis endophthalmitis treatment
JD Torres Pérez,J Olea Cascón,P Crespo Ortiz,F Uriarte Estefanía
Archivos de la Sociedad Espa?ola de Oftalmología , 2004,
Abstract: Caso clínico: En un caso de endoftalmitis exógena producida por Candida parapsilosis, el tratamiento primero con fluconazol oral y posteriormente con anfotericina intravenosa no eliminaron la infección. Sin embargo, el tratamiento con fluconazol tópico e itraconazol oral aparentemente la controlaron. Discusión: Actualmente se acepta que el tratamiento de elección de la endoftalmitis fúngica es la anfotericina B IV, y como alternativa se empiezan a utilizar los azoles. En este caso se ha usado el itraconazol, cuya penetración intraocular y eficacia no han sido aún bien determinadas. Pero, a la vista de los resultados obtenidos, se podría concluir que la penetración intraocular del itraconazol administrado por vía oral puede ser suficiente para controlar la infección, siempre que el hongo causante sea sensible. Clinical case: A case of exogenous Candida parapsilosis endophthalmitis was treated first with oral fluconazol and later with intravenous Anfotericin without success. A subsequent therapy using topical fluconazole and oral itraconazole appeared to be effective in controlled the infection. Discussion: Current elective treatment for fungal endophthalmitis is Anfotericine B iv. An alternative therapy are the azoles. In the reported case itraconazole was used, although its intraocular penetration and effectiveness have not yet been satisfactorily demonstrated. The clinical response in this case leads to the possibility that intraocular oral itraconazole penetration can be sufficient to control infection in cases where the causal fungi is sensitive.
The Krzy? conjecture revisited
María J. Martín,Eric T. Sawyer,Ignacio Uriarte-Tuero,Dragan Vukoti?
Mathematics , 2013,
Abstract: The Krzy\.z conjecture concerns the largest values of the Taylor coefficients of a non-vanishing analytic function bounded by one in modulus in the unit disk. It has been open since 1968 even though information on the structure of extremal functions is available. The purpose of this paper is to collect various conditions that the coefficients of an extremal function (and various other quantities associated with it) should satisfy if the conjecture is true and to show that each one of these properties is equivalent to the conjecture itself. This may provide several possible starting points for future attempts at solving the problem.
