Mining Web Pages Using Features of Rendering HTML Elements in the Web Browser

The Web is the largest repository of useful information available for human users, but it is usual that Web Pages do not provide an API to get access to its information automatically. In order to solve this problem, Information Extractors are developed. We present a new methodology to induce Information Extractors from the Web. It is based on rendering HTML elements in the Web browser. The methodology uses a KDD process to mining a dataset with features of the elements in the Web page. An experimentation over 10 web sites has been made and the results show the effectiveness of the methodology.Ministerio de Ciencia y Tecnología TIN2007-64119Junta de Andalucía P07-TIC-02602Junta de Andalucía P08-TIC-410

Cell Expansion-Dependent Inflammatory and Metabolic Profile of Human Bone Marrow Mesenchymal Stem Cells

Stem cell therapy has emerged as a promising new area in regenerative medicine allowing the recovery of viable tissues. Among the many sources of adult stem cells, bone marrow-derived are easy to expand in culture via plastic adherence and their multipotentiality for differentiation make them ideal for clinical applications. Interestingly, several studies have indicated that MSCs expansion in vitro may be limited mainly due to cell aging related to the number of cell divisions in culture. We have determined that MSCs exhibit a progressive decline across successive passages in the expression of stem cell markers, in plasticity and in the inflammatory response, presenting low immunogenicity. We have exposed human MSCs after several passages to TLRs ligands and analyzed their inflammatory response. These cells responded to pro-inflammatory stimuli (i.e., NOS-2 expression) and to anti-inflammatory cytokines (i.e., HO1 and Arg1) until two expansions, rapidly declining upon subculture. Moreover, in the first passages, MSCs were capable to release IL1β, IL6 and IL8, as well as to produce active MMPs allowing them to migrate. Interestingly enough, after two passages, anaerobic glycolysis was enhanced releasing high levels of lactate to the extracellular medium. All these results may have important implications for the safety and efficacy of MSCs-based cell therapies

On the leakage-power modeling for optimal server operation

Leakage power consumption is a com- ponent of the total power consumption in data cen- ters that is not traditionally considered in the set- point temperature of the room. However, the effect of this power component, increased with temperature, can determine the savings associated with the careful management of the cooling system, as well as the re- liability of the system. The work presented in this paper detects the need of addressing leakage power in order to achieve substantial savings in the energy consumption of servers. In particular, our work shows that, by a careful detection and management of two working regions (low and high impact of thermal- dependent leakage), energy consumption of the data- center can be optimized by a reduction of the cooling budget

Anatomía de hoja, tallo y raíz de Halophytum ameghinoi (Halophytaceae), especie endémica de Argentina

Fernandez, Romina D.; Omar Varela; Patricia L. Albornoz. 2016. “Anato- mía de hoja, tallo y raíz de Halophytum ameghinoi (Halophytaceae) , especie endémica de Argentina”. Lilloa 53 (1). Las plantas halófitas presentan diversos mecanismos de tolerancia a la salinidad, que pueden involucrar modificaciones morfoanatómicas. El presente estudio caracteriza la anatomía de hoja, tallo y raíz de Halophytum ameghinoi y discute los rasgos anatómicos con potencial valor adaptativo a los suelos salinos. El material de estudio procede de dos sitios de la provincia de La Rioja, Argentina (Los Colorados y Alpasinche). Se trabajó con material fresco y fijado en FAA al que se aplicó técnicas histológicas convencionales. Estructuralmente, la hoja es subcircular, equilateral y anfistomática; los estomas son de tipo paracíticos, anfibraquiparacíticos y con 3 a 5 células subsidiarias, además presenta un parénquima central acuífero cuyas células producen mucílago. El tallo muestra diferentes es- tadios de crecimiento. El crecimiento primario posee abundante parénquima cortical y medu- lar y los haces vasculares son colaterales; el crecimiento secundario típico presenta radios floemáticos ensanchados y esclerénquima perivascular, al igual que en raíces con crecimiento secundario. Tanto las hojas, como la raíz y el tallo contienen numerosos cristales de oxalato de calcio. El número de cristales en el parénquima cortical de tallo fue mayor en los indivi- duos de Los Colorados, en correspondencia con la mayor concentración de sales del suelo. El desarrollo del parénquima acuífero y la formación de cristales de oxalato de calcio serían los rasgos más evidentes que presenta H. ameghinoi en la hoja en respuesta de la salinidad del suelo. Mientras que, en tallo y raíz además de los cristales, la presencia de un cilindro de esclerénquima perivascular, formado por fibras con paredes lignificadas, también contribui- ría a la tolerancia de esta especie al ambiente salino

Influence of the nano-micro structure of the surface on bacterial adhesion

Biomaterials failures are frequently associated to the formation of bacterial biofilms on the surface. The aim of this work is to study the adhesion of non motile bacteria streptococci consortium and motile Pseudomonas fluorescens. Substrates with micro and nanopatterned topography were used. The influence of surface characteristics on bacterial adhesion was investigated using optical and epifluorescence microscopy, scanning electron microscopy (SEM) and atomic force microscopy (AFM). Results showed an important influence of the substratum nature. On microrough surfaces, initial bacterial adhesion was less significant than on smooth surfaces. In contrast, nanopatterned samples showed more bacterial attachment than the smooth control. It was also noted a remarkable difference in morphology, orientation and distribution of bacteria between the smooth and the nanostructured substrate. The results show the important effect of substratum nature and topography on bacterial adhesion which depended on the relation between roughness characteristics dimensions and bacterial size

Electron-beam irradiation at low doses preserves dietary fiber content in Boletus edulis Bull.: Fr. wild mushroom

Mushrooms are considered a good source of non-digestible carbohydrates, which represent a group of dietary fiber with various beneficial health effects to humans e.g., improve the function of the alimentary tract, helps lower postprandrial blood glucose, insuline and cholesterol, strengthens the immune system and antitumor activity [1]. Due to delicate nature, mushrooms suffer severe conservation problems and have to be processed to extend their short shelf-life. Drying is one of the most used processes for preserving mushrooms and, for decontamination, electron-beam irradiation also proved its technological feasibility to be safely used for reduce food losses [2]. In the present study, electron-beam irradiation (2, 6 and 10 kGy) was applied to dried samples of Boletus edulis Bull.: Fr. in order to evaluate the effects on fiber composition. The fruiting bodies were collected in Trás-os-Montes (Northeast of Portugal) in November 2012 and dried at 30 ºC in an oven. The irradiation was performed at the Institute of Nuclear Chemistry and Technology, in Warsaw, Poland. The determination of total available carbohydrate was carried out by the Anthrone method [3]. AOAC enzymatic-gravimetric methods, 993.19 and 991.42 were used for soluble and insoluble dietary fiber analysis [4]. B. edulis presented an important percentage of dietary fiber, soluble and insoluble in different ratios. The irradiated samples, especially for higher doses, gave some significant changes in total available carbohydrates and dietary fibers content; but, a lower dose (2 kGy) preserves carbohydrates, soluble and insoluble fiber content. Electron-beam irradiation at low doses is a feasible choice to extend mushrooms shelf-life and preserves the dietary fiber content.FCT and COMPETE/QREN/UE- strategic projects PEst-OE/AGR/UI0690/2011 (CIMO) and PEst-C/EQB/LA0006/2011 (REQUIMTE); grant SFRH/BD/76019/2011 to A.

Effects of gamma irradiation on macro and microelements of Boletus edulis Bull.: Fr. and Hydnum repandum L.: Fr.

Mushrooms are considered excellent sources of minerals, being necessary to know the levels of essential elements in the edible species [1]. Mineral elements are classified in macro (e.g., Ca, Mg, Na, K) and microelements (e.g., Fe, Cu, Mn, Zn) with functions that include maintaining acid-base balance, osmotic regulation, oxygen transport and enzymatic cofactors [2-3]. Mushrooms need special caution in their conservation. Accordingly, treatments such as gamma rays have been applied to improve their shelf life and reduce health hazards caused by pathogenic microorganisms [4]. In this work, gamma irradiation was applied to Boletus edulis Bull.: Fr. and Hydnum repandum L.: Fr. to assess the effects on the minerals composition. The fruiting bodies were collected in Trás-os-Montes (Northeast of Portugal) in November 2012. Fresh samples were irradiated in experimental equipment with four 60Co sources, at 1 and 2 kGy. The studied mushrooms presented high levels of macro and microelements. Up to the applied doses, some significant differences were observed. However, in most cases, changes did not follow a marked tendency, being more likely to be derived from the natural variability in mineral accumulation as a result of mushroom growth in different ecosystems. Hence, irradiation treatment, using gamma rays up to 2 kGy, is a suitable technique to disinfest and/or decontaminate wild mushrooms, independently of their species or physical state

Thermoremanence anomaly in Fe-Zr(B,Cu) Invar metallic glasses: Volume expansion induced ferromagnetism

We report the existence of a thermally induced sharp increase of thermoremanence around the Curie temperature of Invar-like Fe-Zr(B,Cu) soft magnetic glasses. Neutron-diffraction measurements indicate that a true enhancement of the average local magnetic moment, rather than only a change in the domain structure, occurs. Such enhancement has been tentatively attributed to the increasing volume expansion that takes place beyond the Curie temperature and reinforces ferromagnetism in some low-density clusters
