Magnetic Cross-Linked Enzyme Aggregates (mCLEAs) of Candida antarctica Lipase: An Efficient and Stable Biocatalyst for Biodiesel Synthesis
(Public Library Science, 2014-12-31)
Enzyme-catalyzed production of biodiesel is the object of extensive research due to the global shortage of fossil fuels and increased environmental concerns. Herein we report the preparation and main characteristics of a ...
Three-dimensional growth as multicellular spheroid activates the proangiogenic phenotype of colorectal carcinoma cells via LFA-1-dependent VEGF: implications on hepatic micrometastasis
Valcarcel, María; Arteta Ruiz, Beatriz 
; Jaureguibeitia, Arrate; Lopategi Martínez, Aritz; Martínez, Iñigo; Mendoza, Lorea; Muruzabal, Francisco J.; Salado, Clarisa; Vidal Vanaclocha, Fernando (BioMed Central, 2008-10)
; Jaureguibeitia, Arrate; Lopategi Martínez, Aritz; Martínez, Iñigo; Mendoza, Lorea; Muruzabal, Francisco J.; Salado, Clarisa; Vidal Vanaclocha, Fernando (BioMed Central, 2008-10)
Background: The recruitment of vascular stromal and endothelial cells is an early event occurring during cancer cell growth at premetastatic niches, but how the microenvironment created by the initial three-dimensional ...
Detection of Atomic Scale Changes in the Free Volume Void Size of Three-Dimensional Colorectal Cancer Cell Culture Using Positron Annihilation Lifetime Spectroscopy
Axpe Iza, Eneko; López Euba, Tamara; Castellanos Rubio, Ainara; Mérida Sanz, David; ; Plaza-Izurieta, Leticia; Fernández-Jiménez, Nora; Plazaola Muguruza, Fernando ; Bilbao Catalá, José Ramón (Public Library of Science, 2014-01-02)
; Bilbao Catalá, José Ramón (Public Library of Science, 2014-01-02)
Positron annihilation lifetime spectroscopy (PALS) provides a direct measurement of the free volume void sizes in polymers and biological systems. This free volume is critical in explaining and understanding physical and ...
Early Functional Deficit and Microglial Disturbances in a Mouse Model of Amyotrophic Lateral Sclerosis
(Public Library of Science, 2012-04-25)
Background: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterized by selective motoneurons degeneration. There is today no clear-cut pathogenesis sequence nor any treatment. However growing ...
Learning and Recognition of a Non-conscious Sequence of Events in Human Primary Visual Cortex
Rosenthal, Clive R.; Andrews, Samantha K.; Antoniades, Chrystalina A.; Kennard, Christopher; Soto, David (Current Biology, 2016)
(Current Biology, 2016)
Human primary visual cortex (V1) has long been
associated with learning simple low-level visual discriminations
[1] and is classically considered outside
of neural systems that support high-level cognitive
behavior in ...
A Featureless Approach to 3D Polyhedral Building Modeling from Aerial Images
(MDPI, 2011)
This paper presents a model-based approach for reconstructing 3D polyhedral building models from aerial images. The proposed approach exploits some geometric and photometric properties resulting from the perspective ...
Resveratrol prevents inflammation-dependent hepatic melanoma metastasis by inhibiting the secretion and effects of interleukin-18
(BioMed Central, 2011-05)
Background: Implantation and growth of metastatic cancer cells at distant organs is promoted by inflammation-dependent mechanisms. A hepatic melanoma metastasis model where a majority of metastases are generated via ...
A Self-Referencing Intensity Based Polymer Optical Fiber Sensor for Liquid Detection
Sánchez Montero, David; Vázquez, Carmen; Möllers, Ingo; Arrue Aramburu, Juan Antonio ; Jäger, Dieter (MDPI, 2009-08)
; Jäger, Dieter (MDPI, 2009-08)
A novel self-referencing fiber optic intensity sensor based on bending losses of a partially polished polymer optical fiber (POF) coupler is presented. The coupling ratio (K) depends on the external liquid in which the ...
Biotic vs. Abiotic Control of Decomposition: A Comparison of the Effects of Simulated Extinctions and Changes in Temperature
Boyero González, María Luz ; Cardinale, Bradley J.; Bastian, Mikis; Pearson, Richard G. (Public Library of Science, 2014-01)
; Cardinale, Bradley J.; Bastian, Mikis; Pearson, Richard G. (Public Library of Science, 2014-01)
The loss of species is known to have significant effects on ecosystem functioning, but only recently has it been recognized that species loss might rival the effects of other forms of environmental change on ecosystem ...
Autophagic Marker MAP1LC3B Expression Levels Are Associated with Carotid Atherosclerosis Symptomatology
(Public Library Science, 2014-12-12)
Objectives: The mechanism by which atheroma plaque becomes unstable is not completely understood to date but analysis of differentially expressed genes in stable versus unstable plaques may provide clues. This will be ...
