Three-dimensional growth as multicellular spheroid activates the proangiogenic phenotype of colorectal carcinoma cells via LFA-1-dependent VEGF: implications on hepatic micrometastasis
(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 ...
A Self-Referencing Intensity Based Polymer Optical Fiber Sensor for Liquid Detection
(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 ...
Influence of Two Vaccination Campaigns on Genetic Diversity of Invasive Neisseria meningitidis Isolates in Northern Spain (1997–2008)
(Public Library of Science, 2009-12-30)
Background: Neisseria meningitidis diversifies rapidly, due to its high recombination rates. The aim of this study was to analyze the possible impact of two vaccination campaigns (a once-off A/C polysaccharide vaccination ...
Design of a Sensor Based on Plastic Optical Fibre (POF) to Measure Fluid Flow and Turbidity
(MDPI, 2009-05)
Although many optical fibre applications are based on their capacity to transmit optical signals with low losses, it can also be desirable for the optical fibre to be strongly affected by a certain physical parameter in ...
Differential Micro RNA Expression in PBMC from Multiple Sclerosis Patients
(Public Library of Science, 2009-07-20)
Differences in gene expression patterns have been documented not only in Multiple Sclerosis patients versus healthy controls but also in the relapse of the disease. Recently a new gene expression modulator has been identified: ...
Molecular Components and Functions of the Endocannabinoid System in Mouse Prefrontal Cortex
(Public Library of Science, 2007-08-08)
Background. Cannabinoids have deleterious effects on prefrontal cortex (PFC)-mediated functions and multiple evidences link the endogenous cannabinoid (endocannabinoid) system, cannabis use and schizophrenia, a disease in ...
A Model of Ischemia-Induced Neuroblast Activation in the Adult Subventricular Zone
(Public Library of Science, 2009-04-23)
We have developed a rat brain organotypic culture model, in which tissue slices contain cortex-subventricular zone-striatum regions, to model neuroblast activity in response to in vitro ischemia. Neuroblast activation has ...
Global Self-Organization of the Cellular Metabolic Structure
(Public Library Science, 2008-08)
Background: Over many years, it has been assumed that enzymes work either in an isolated way, or organized in small catalytic groups. Several studies performed using "metabolic networks models'' are helping to understand ...
The Number of Catalytic Elements Is Crucial for the Emergence of Metabolic Cores
(Public Library of Science, 2009-10-19)
Background: Different studies show evidence that several unicellular organisms display a cellular metabolic structure characterized by a set of enzymes which are always in an active state (metabolic core), while the rest ...
Gene Expression Profiling in Limb-Girdle Muscular Dystrophy 2A
(Public Library of Science, 2008-11-18)
Limb-girdle muscular dystrophy type 2A (LGMD2A) is a recessive genetic disorder caused by mutations in calpain 3 (CAPN3). Calpain 3 plays different roles in muscular cells, but little is known about its functions or in ...
