A previous study in Belgium revealed that genetic material of Fasciola sp. was present in four local snail species: Galba truncatula, Radix peregra, Radix ovata and Lymnaea stagnalis. Laboratory cultures of these four species were experimentally infected with F. hepatica. The collected metacercariae were fed to rats and the infection in that vertebrate hosts was monitored through several techniques. The mortality rates in the breeding unit was less than 10 % in G. truncatula, R. peregra, and L. stagnalis colonies. Microscopy revealed the presence of larval stages in 78.3 % and 48 % of G. truncatula and R. peregra snails, respectively. These data were confirmed by a PCR that amplifies a parasite specific sequence. R. peregra shed fewer metacercariae and more irregularly than G. truncatula. In R. ovata and L. stagnalis the infection rates were low. Specific DNA was detected in both cases by PCR but no metacercariae were shed. The metacercariae shed by R. peregra were as infective to rats as those from G. truncatula. The PCR technique was more sensitive than microscopic examination. This study demonstrated that R. peregra may act as an accidental intermediate host for F. hepatica in Belgium. [less ▲]

A previous study conducted in Belgium revealed that genetic material of Fasciola sp. was present in snail species belonging to the genus Radix. Here, these snails were collected and identified by DNA-based techniques as Radix labiata and Radix balthica. These two species and Galba truncatula (the major intermediate host in Europe) were experimentally infected with Fasciola hepatica. The resulting metacercariae were fed to rats and the infection was monitored using several techniques. Microscopy revealed the presence of larval stages in 78.3, 45, and 6.25% of G. truncatula, R. labiata, and R. balthica snails, respectively. These results were confirmed by a PCR that amplifies a Fasciola sp. specific sequence. Furthermore, this PCR was found to be more sensitive than microscopic examination. R. labiata shed fewer metacercariae than G. truncatula but these were as infective to rats as those shed by G. truncatula. This study demonstrates that R. labiata may act as an incidental intermediate host for F hepatica in Belgium. (C) 2007 Elsevier B.V. All rights reserved. [less ▲]

La presente ricerca aveva lo scopo di studiare le influenze dello stile di attaccamento adulto sulla qualità del supporto emotivo fra il paziente oncologico e il suo caregiver di riferimento e sull’alleanza di lavoro con i medici di reparto, durante il ricovero in una struttura hospice, specializzata nella gestione della fase terminale della malattia. Poiché lo stile di attaccamento adulto sembra giocare un ruolo importante nella gestione dello stress psicologico percepito dall’individuo nelle circostanze stressanti e nella capacità di fare affidamento sugli altri (Florian & Mikulincer, 1998), abbiamo ipotizzato che anche nella condizione di disagio estremo della fase terminale di una malattia, l’attaccamento sicuro potesse aiutare il soggetto ad affrontare le difficoltà del momento e che, invece, un attaccamento insicuro tendesse ad aumentare la vulnerabilità e l’angoscia (Mikulincer & Orbach, 1995). Lo studio si è proposto di verificare l’ipotesi secondo cui lo stile di attaccamento tenda a influenzare due aspetti importanti della fase terminale della malattia: la qualità del supporto emotivo dato dalla relazione con il caregiver e la qualità dell’alleanza di lavoro con il medico curante. Ci aspettavamo che i malati con attaccamento sicuro tendessero a percepire più positivamente la qualità del supporto emotivo con il caregiver e, analogamente, a valutare più favorevolmente l’alleanza di lavoro con il medico, rispetto ai pazienti insicuri.

"FASST" stands for "fMRI Artefact rejection and Sleep Scoring Toolbox". This M/EEG toolbox is developed by researchers from the Cyclotron Research Centre, University of Li ege, Belgium, with the financial support of the Fonds de la Recherche Scienti que-FNRS, the Queen Elizabeth's funding, and the University of Li ege. On Dr. Pierre Maquet's impulse we started writing these tools to analyze our sleep EEG-fMRI data and tackle four crucial issues: * Continuous M/EEG. Long multi-channel recording of M/EEG data can be enormous. These data are cumbersome to handle as it usually involves displaying, exploring, comparing, chunking, appending data sets, etc. * EEG-fMRI. When recording EEG and fMRI data simultaneously, the EEG signal acquired contains, on top of the usual neural and ocular activity, artefacts induced by the gradient switching and high static eld of an MR scanner. The rejection of theses artefacts is not easy especially when dealing with brain spontaneous activity. * Scoring M/EEG. Reviewing and scoring continuous M/EEG recordings, such as is common with sleep recordings, is a tedious task as the scorer has to manually browse through the entire data set and give a \score" to each time-window displayed. * Waves detection. Continuous and triggerless recordings of M/EEG data show specifi c wave patterns, characteristic of the subject's state (e.g., sleep spindles or slow waves). Their automatic detection is thus important to assess those states. [less ▲]

We started writing the “fMRI artefact rejection and sleep scoring toolbox”, or “FASST”, to process our sleep EEG-fMRI data, that is, the simultaneous recording of electroencephalographic and functional magnetic resonance imaging data acquired while a subject is asleep. FAST tackles three crucial issues typical of this kind of data: (1) data manipulation (viewing, comparing, chunking, etc.) of long continuous M/EEG recordings, (2) rejection of the fMRI-induced artefact in the EEG signal, and (3)manual sleep-scoring of the M/EEG recording. Currently, the toolbox can efficiently deal with these issues via a GUI, SPM8 batching system or handwritten script. The tools developed are, of course, also useful for other EEG applications, for example, involving simultaneous EEG-fMRI acquisition, continuous EEG eye-balling, and manipulation. Even though the toolbox was originally devised for EEG data, it will also gracefully handle MEG data without any problem. “FAST” is developed in Matlab as an add-on toolbox for SPM8 and, therefore, internally uses its SPM8-meeg data format. “FAST” is available for free, under the GNU-GPL.

Despite the growing importance of longitudinal data in neuroimaging, the standard analysis methods make restrictive or unrealistic assumptions (e.g., assumption of Compound Symmetry--the state of all equal variances and equal correlations--or spatially homogeneous longitudinal correlations). While some new methods have been proposed to more accurately account for such data, these methods are based on iterative algorithms that are slow and failure-prone. In this article, we propose the use of the Sandwich Estimator method which first estimates the parameters of interest with a simple Ordinary Least Square model and second estimates variances/covariances with the "so-called" Sandwich Estimator (SwE) which accounts for the within-subject correlation existing in longitudinal data. Here, we introduce the SwE method in its classic form, and we review and propose several adjustments to improve its behaviour, specifically in small samples. We use intensive Monte Carlo simulations to compare all considered adjustments and isolate the best combination for neuroimaging data. We also compare the SwE method to other popular methods and demonstrate its strengths and weaknesses. Finally, we analyse a highly unbalanced longitudinal dataset from the Alzheimer's Disease Neuroimaging Initiative and demonstrate the flexibility of the SwE method to fit within- and between-subject effects in a single model. Software implementing this SwE method has been made freely available at http://warwick.ac.uk/tenichols/SwE. [less ▲]

A novel photochemical water-based approach for the preparation of nanoparticles of polymerized thiophene (Th), thiophene methanol (ThM), or their mixtures (Th-co/or-ThM) was developed. The influence of 3-[(2-acryloyloxy)methyl] thiophene (ATh) as cross-link agent on the stability of the nanoparticles and on their performances was investigated. The occurrence of a polymerization process was confirmed by Fourier transform infrared (FT-IR), UV and fluorescence emission spectroscopies. Nanoparticles with very narrow size distribution (0.0092–0.105 ATh cross-linked, 0.0635–0.272 uncross-linked) and ideal spherical shape (radius 35–47 nm ATh cross-linked, 49–109 nm uncross-linked) were obtained whatever the reaction composition. The size of the particles was found to depend strongly on the level of ATh-stabilization and to diminish upon increase of the ATh content. In contrast, in the same order, their thermal stability shifted toward higher temperatures. Thermal decomposition of the nanoparticles led to formation of carbon-nanoobjects, as observed by transmission electron microscopy, FT-IR, and RAMAN spectroscopies. The re-dispersibility of the dry Th-co/or-ThM nanoparticles in some conventional monomers and solvents has been estimated. [less ▲]

Face recognition is supposed to be fast. However, the actual speed at which faces can be recognized remains unknown. To address this issue, we report two experiments run with speed constraints. In both experiments, famous faces had to be recognized among unknown ones using a large set of stimuli to prevent pre-activation of features which would speed up recognition. In the first experiment (31 participants), recognition of famous faces was investigated using a rapid go/no-go task. In the second experiment, 101 participants performed a highly time constrained recognition task using the Speed and Accuracy Boost- ing procedure. Results indicate that the fastest speed at which a face can be recognized is around 360–390 ms. Such latencies are about 100 ms longer than the latencies recorded in similar tasks in which subjects have to detect faces among other stimuli. We discuss which model of activation of the visual ventral stream could account for such latencies. These latencies are not consistent with a purely feed-forward pass of activity throughout the visual ventral stream. An alternative is that face recognition relies on the core network underlying face processing identified in fMRI studies (OFA, FFA, and pSTS) and reentrant loops to refine face representation. However, the model of activation favored is that of an activation of the whole visual ventral stream up to anterior areas, such as the perirhinal cortex, combined with parallel and feed-back processes. Further studies are needed to assess which of these three models of activation can best account for face recognition. [less ▲]
