α2,3-Sialyltransferase ST3Gal III Modulates Pancreatic Cancer Cell Motility and Adhesion In Vitro and Enhances Its Metastatic Potential In Vivo
(Public Library of Science, 2010-09-01)
Background: Cell surface sialylation is emerging as an important feature of cancer cell metastasis. Sialyltransferase expression has been reported to be altered in tumours and may account for the formation of sialylated ...
Methods for cleaning the BOLD fMRI signal
(NeuroImage, 2017)
Blood oxygen-level-dependent functional magnetic resonance imaging (BOLD fMRI) has rapidly become a popular technique for the investigation of brain function in healthy individuals, patients as well as in animal studies. ...
High-resolution magnetic resonance imaging reveals nuclei of the human amygdala: manual segmentation to automatic atlas
(NeuroImage, 2017)
The amygdala is composed of multiple nuclei with unique functions and connections in the limbic system and to the rest of the brain. However, standard in vivo neuroimaging tools to automatically delineate the amygdala into ...
Local Productive Arrangements and local development in non-metropolitan municipalities of Sao Paulo, Brazil
(Instituto de Economía Aplicada a la Empresa (Universidad del País Vasco UPV/EHU), 2017-11)
[EN] The objective of this paper consists in analysing whether Local Productive Arrangements (APLs) - the Brazilian version of a cluster- can improve the local development of their host municipalities. Most studies concern ...
Improved memory for information learnt before alcohol use in social drinkers tested in a naturalistic setting
(Scientific Reports, 2017)
Alcohol is known to facilitate memory if given after learning information in the laboratory; we aimed to investigate whether this effect can be found when alcohol is consumed in a naturalistic setting. Eighty-eight social ...
Time-Resolved Resting-State Functional Magnetic Resonance Imaging Analysis: Current Status, Challenges, and New Directions
(Brain Connectivity, 2017)
Time-resolved analysis of resting-state functional magnetic resonance imaging (rs-fMRI) data allows researchers to extract more information about brain function than traditional functional connectivity analysis, yet a ...
Tobacco control in 30 European countries from 2005 to 2007 with an update in 2010
(Instituto Vasco de Criminología, 2010)
[EN] In this article the results of the surveys about the tobacco control activity in European countries
made in 2005 and 2007–using the Tobacco Control Scale (TCS)– are described. The most effective tobacco control ...
Optimal Resting-Growth Strategies of Microbial Populations in Fluctuating Environments
(Public Library of Science, 2011-04-15)
Bacteria spend most of their lifetime in non-growing states which allow them to survive extended periods of stress and starvation. When environments improve, they must quickly resume growth to maximize their share of limited ...
Fixed Point and Best Proximity Theorems under Two Classes of Integral-Type Contractive Conditions in Uniform Metric Spaces
(Hindawi Publishing Corporation, 2010)
This paper investigates the existence of fixed points and best proximity points of p-cyclic self-maps on a set of subsets of a certain uniform space under integral-type contractive conditions. The parallel properties of ...
Global Stability of Polytopic Linear Time-Varying Dynamic Systems under Time-Varying Point Delays and Impulsive Controls
(Hindawi Publishing Corporation, 2010)
This paper investigates the stability properties of a class of dynamic linear systems possessing several linear time-invariant parameterizations (or configurations) which conform a linear time-varying polytopic dynamic ...
