YBa2Cu3O7-delta coatings were deposited by electrophoretic deposition (EPD) onto Ni substrates. Particles of different sizes and shapes were used in order to study the influence of the powder microstructure on the film density. Texturation of the thick films was induced by application of a magnetic field during the electrophoretic deposition. X-ray diffraction analysis has clearly shown preferred c-axis alignment of the YBa2Cu3O7-delta films along the direction normal to the substrate surface. Scanning electron microscopy and optical polarised light microscopy were used to characterise the microstructure of the coatings, revealing a nonrandom platelets organisation. [less ▲]

It is clear that even low rate smoking is hazardous for health, the risk being independently increased by the daily number of cigarettes smoked and by the duration of smoking. The question raised is thus: will an adolescent experimenter be a non smoker, an experimenter for ever, a regular smoker, light or heavy? This short review shows that there are numerous factors from genetics, to familial environment not limited to tobacco issues, smoking situation at school as well as school performances of the student, and also individual psychological characteristics. The experimenter is a very good target for smoking cessation actions and should deserve particular attention from preventive medicine and, thus, from school medicine, before he becomes a regular smoker, who will be more resistant to smoking cessation programs.

The purpose of this study was to investigate the reproducibility of findings derived from a new iso-inertial dynamometer during bench press (BP) and squat (SQ) and to provide descriptive data for recreational athletes. A position transducer and accelerometer were combined to assess velocity and power during free weight lifting exercises. Simulated movement with a pulley system revealed the excellent technical consistency of the dynamometer. Sixteen male subjects participated in the study. Iso-inertial tests consisted of lifting as fast as possible four different relative loads (35, 50, 70, 90% 1RM in BP and 45, 60, 75, 90% 1RM in SQ). The test was repeated one week later. Analysis of variance revealed no significant variation between sessions or trials. Reproducibility was better in velocity than in power, although it remained fairly good in both exercises (coefficients of variation [CV] never exceeding 10%) except for the time to peak power parameter. Descriptive data confirmed the classical force-velocity and force-power relationships for BP and SQ. In conclusion, this study demonstrated reliable measurements in BP and SQ iso-inertial exercises. Monitoring force-velocity and force-power relationships offers an original functional approach in strength training supervision. [less ▲]

Background: Ineffective physicians' communication skills have detrimental consequences for patients and their relatives, such as insufficient detection of psychological disturbances, dissatisfaction with care, poor compliance, and increased risks of litigation for malpractice. These ineffective communication skills also contribute to everyday stress, lack of job satisfaction, and burnout among physicians. Literature shows that communication skills training programs may significantly improve physicians' key communication skills, contributing to improvements in patients' satisfaction with care and physicians' professional satisfaction. This paper describes a Belgian Interuniversity Curriculum (BIC) theoretical roots, principles, and techniques developed for junior physicians specializing in various disciplines dealing with cancer patients. Curriculum description: The 40-h training focuses on two domains: stress management skills and communication skills with cancer patients and their relatives. The teaching method is learner-centered and includes a cognitive, behavioral, and affective approach. The cognitive approach aims to improve physicians' knowledge and skills on the two domains cited. The behavioral approach offers learners the opportunity to practice these appropriate skills through practical exercises and role plays. The affective approach allows participants to express attitudes and feelings that communicating about difficult issues evoke. Such an intensive course seems to be necessary to facilitate the transfer of learned skills in clinical practice. Conclusions: The BIC is the first attempt to bring together a stress management training course and a communication training course that could lead not only to communication skills improvements but also to burnout prevention.

A new automate, ImmunoCap 250 has recently been released by Sweden Diagnostics for the determination of specific and total IgE. We have evaluated its analytical performances (intra- and inter-assay precision, linearity, recovery and sensibility) and compared the results obtained by Unicap 100 on 149 samples positive for 12 different allergens and 30 samples containing different concentrations of total IgE. Intra- and inter-assay precision are less than 10% excepted for the specific IgE of one allergen (i3, common wasp), but still in accordance with the NCCLS guidelines. The sensibility is 0.01 kU(A)/L for specific and 0.35 kU/L for total IgE. The method is linear up to 5000 kU/L for total and at least 80 kU(A)/L for specific IgE. The recovery test showed a recovery of the International standard WHO 75/502 between 85 and 115%, with a mean of 103%. The correlation coefficient between the ImmunoCap 250 and Unicap 100 is 0.9866 and 0.9984 for specific and total IgE respectively. ImmunoCap 250 is a good solution for laboratories that perform twenty to thirty thousand determinations. [less ▲]

This paper gives an overview of experimental and theoretical aspects of the ion mobility spectrometry technique coupled to mass spectrometry. These aspects are illustrated by a recent study on the conformation of a DNA sequence capable of forming intramolecular G-quadruplex folds. This sequence is found in the promoter of the gene coding for the c-Myc protein. The comparison between experimental collision cross sections determined by ion mobility spectrometry and theoretical cross sections calculated for several model structures allows demonstrating that ions of low charge states have conserved the G-quadruplex parallel fold that was present in solution. Mass spectrometry also revealed the presence of a dimer, which conformation was interpreted using ion mobility : this structure consists of two parallel monomers stacked with each other. [less ▲]

Digital image correlation (DIC) is an optical–numerical full-field displacement measuring technique, which is nowadays widely used in the domain of experimental mechanics. The technique is based on a comparison between pictures taken during loading of an object. For an optimal use of the method, the object of interest has to be covered with painted speckles. In the present paper, a comparison is made between three different speckle patterns originated by the same reference speckle pattern. A method is presented for the determination of the speckle size distribution of the speckle patterns, using image morphology. The images of the speckle patterns are numerically deformed based on a finite element simulation. Subsequently, the displacements are measured with DIC-software and compared to the imposed ones. It is shown that the size of the speckles combined with the size of the used pixel subset clearly influences the accuracy of the measured displacements. [less ▲]

Since the discovery of the P300 component, a large number of studies have been conducted with the aim to find abnormalities of this psychophysiological marker among the main psychiatric disorders. The first studies were very promising, but successive findings were rather controversial resulting in two main positions (the pros and the cons) as regard to the usefulness of P300 in clinical psychopathology. However, P300 studies provide interesting findings concerning information processing in psychopathology. Moreover, other Event-Related Potentials (ERPs), such as the Mismatch Negativity (MMN) and the Error-Related Negativity (ERN) are particularly interesting for the study of cognitive processes in psychopathology. In this review, the author will give an overview of the main findings of P300, MMN and ERN values in psychopathology from a clinical and a cognitive point of view. After a brief description of the rationale of ERPs, the findings in schizophrenia, depression, alcoholism, posttraumatic stress disorder, panic disorder, and obsessive-compulsive disorder will be sequentially reviewed. The diagnostic usefulness of P300 in psychopathology is limited, but could be increased if variables known to influence P300 amplitude or latency are controlled. Doubtless, grouping two or more different ERP components would greatly improve the usefulness of the clinical applications of brain potentials. On the other hand, a growing number of studies have provided evidence of the relevance of ERPs to investigate cognitive processes in psychopathology. [less ▲]

Several studies found strong relationships between main personality dimensions and emotions, and more particularly between neuroticism and negative emotions, as well as between extraversion and positive ones. In these studies, personality was mainly assessed with respect to the big five model, and emotions were evaluated with subjective rating scales. To extend the exploration of the associations between personality and emotion, the aim of the present study was to investigate the relationships between Cloninger's dimensions of personality and emotional reactivity assessed by skin conductance response (SCR). In 55 normal subjects, SCR was recorded while they were presented pictures selected as positive, negative and neutral from the International Affective Picture System. The results showed no influence of personality on response magnitude, but subjects with higher harm avoidance scores showed longer half-recovery times for negative relative to neutral pictures. This result is consistent with the dispositional bias of harm avoidance to respond intensely to signals of aversive stimuli. (c) 2006 Elsevier Ltd. All rights reserved. [less ▲]

Transient starch production is thought to strongly control plant growth and response to elevated CO2. We tested this hypothesis with an experimentally based mechanistic model in Arabidopsis thaliana. Experiments were conducted on wild-type (WT) A. thaliana, starch-excess (sex1) and starchless (pgm) mutants under ambient and elevated CO2 conditions to determine parameters and validate the model. The model correctly predicted that mutant growth is approx. 20% of that in WT, and the absolute response of both mutants to elevated CO2 is an order of magnitude lower than in WT. For sex1, direct starch unavailability explained the growth responses. For pgm, we demonstrated experimentally that maintenance respiration is proportional to leaf soluble sugar concentration, which gave the necessary feedback mechanism on modelled growth. Our study suggests that the effects of sugar-starch cycling on growth can be explained by simple allocation processes, and the maximum rate of leaf growth (sink capacity) exerts a strong control over the response to elevated CO2 of herbaceous plants such as A. thaliana.
