Two techniques with the common objective to integrate multiple view holographic interferometry in one optical head are presented: multi recordings in a photorefractive BSO crystal and the use of a series of BSO crystals as the recording medium. After a description of the principles we will show their application to holographic interferometry. The results will be presented and a comparison of the two methods, based on the quality of the interferograms, will be performed, showing the respective advantages and limitations of each technique compared to the other and to classical experiment of holographic interferometry. Up to four holograms have been recorded in one crystal, or two holograms in two crystals, corresponding to the four positions of illumination of the object [less ▲]

AIMS: Off-line post-processing of colour tissue Doppler from digital loops may allow objective quantification of dobutamine stress echocardiography. We assessed the reproducibility of off-line measurements of regional myocardial velocities. METHODS AND RESULTS: Nine observers analysed 10 studies, each making 2400 observations. Coefficients of variation in basal segments from apical windows, at rest and maximal stress, were 9-14% and 11-18% for peak systolic velocity, 16-18% and 17-19% for time-to-peak systolic velocity, 9-17% and 18-24% for systolic velocity time integral, and 18-23% and 21-27% for systolic acceleration. Coefficients of variation for diastolic velocities in basal segments at rest were 11-40%. Coefficients of variation for peak systolic velocity were 10-24% at rest and 14-28% at peak in mid segments, and 19-53% and 29-69% in apical segments. From parasternal windows coefficients of variation for peak systolic velocity were 14-16% in basal posterior, and 19-29% in mid-anterior segments. High variability makes measurement unreliable in apical and basal anterior septal segments. The feasibility of obtaining traces was tested in 92 subjects, and >90% in all basal and mid segments apart from the anterior septum. CONCLUSION: Quantification of myocardial functional reserve by off-line analysis of colour tissue Doppler acquired during dobutamine stress is feasible and reproducible in 11 segments of the left ventricle. The most reliable measurements are systolic velocities of longitudinal motion in basal segments. [less ▲]

This paper describes the monitoring of Salmonella in a closed pig production system in Belgium over a 2-year period. A sampling scheme including animal feeds and carcasses was designed to cover the entire chain of production from farrow to finishing pigs. Salmonella was detected by a method based on the use of semisolid Rappaport-Vassiliadis as a selective medium. The serotypes of the isolated strains were determined, and the antibiotic resistance of these strains to six antibiotics was also investigated. Feeds were found to be more contaminated than expected (10.2%, 34 of 332 samples). The percentage of positive fecal samples for pregnant sows (8.1%, 11 of 135 samples) was significantly higher than that for young and lactating sows (2.9%, 11 of 378 samples) (P<0.05). The percentage of positive samples for colon contents collected at the slaughterhouse (47.3%, 88 of 186 samples) was significantly higher than that for feces collected during the fattening stage (5.6%, 18 of 320 samples) (P<0.001). For carcass swab samples, the observed prevalence was 11.2% (17 of 152 samples). On farms, Salmonella recovery levels were higher for overshoe samples than for fecal samples, except for pregnant sows. Salmonella Typhimurium was the most frequently isolated serotype (32.2%, 55 of 171 samples), while Salmonella Brandenburg was predominant in the colon contents collected at the abattoir (21.4%, 18 of 84 samples). Feeds harbored a wide diversity of serotypes of minor epidemiological significance. Of 55 isolated strains of Salmonella Typhimurium, 11 (20%) were resistant to tetracycline, ampicillin, choramphenicol, streptomycin, trimethoprim, and nalidixic acid (R Type TeAmCSNa), while 12 (21.8%) were resistant to all of these antibiotics except nalidixic acid (R Type TeAmCS). The majority of Salmonella Typhimurium strains that exhibited resistance to more than four antimicrobial agents were characterized as Salmonella Typhimurium DT104 or as being closely related to Salmonella Typhimurium DT104 (7 of 12 isolates). In conclusion, our system of surveillance is effective in identifying most points of contamination in the production chain and will be useful in ongoing efforts to develop a Salmonella-free production system.

The use of muscle relaxants, considered until recently as common practice in current neurosurgical anaesthesia protocols, becomes increasingly more questionable today. The reasons rely on the evolution of neurosurgery including the advent of new surgical techniques, the evolution of anaesthesia having the benefit of new drugs and devices, and the rationale for using muscle relaxants balanced against their potential side-effects and possible pharmacodynamic alterations in neurosurgical patients.

Invasive fungal infections are a rare but important cause of morbidity and mortality among patients with severely compromised host defenses. Despite considerable advances in antifungal therapies over the past years, invasive mycoses remain a stubborn and dramatic problem. Voriconazole is a new triazole antifungal agent which confers a relative survival benefit in fluconazole-resistant invasive candidiasis, and in invasive aspergillosis, fusariosis and Scedosporium infections as well.

Reasons for performing study: There is currently little published information about the effects of endothelin-1 (ET-1), a potent endogenous spasmogen of vascular and airway smooth muscle, on pulmonary vasculature and airways or which ET receptor subtypes mediate ET-1 induced vasoconstrictive and bronchoconstrictive action in the horse. Objectives: To investigate the effect of endothelin-1 (ET-1) on smooth muscle from isolated equine pulmonary artery and bronchus. In addition, the roles of ETA and ETB receptors in ET-1 mediated contraction in these tissues were assessed. Methods: The force generation of ring segments from pulmonary arteries or third-generation airways (obtained from horses subjected to euthanasia for orthopaedic reasons) were studied in an organ bath at 37°C in response to exogenous endothelin and selective endothelin A (BQ123) or B receptor (BQ788) antagonists. Results: ET-1 produced concentration-dependent contractions of the equine pulmonary artery and bronchus. The threshold for contraction was 10-10 and 10-9 mol/l ET-1 for pulmonary artery and bronchus, respectively. The maximal contraction induced by the highest ET-1 concentration (10-7 mol/l) was 173 and 194% of the contraction obtained with 100 mmol/l KCl in pulmonary artery and bronchus, respectively. ET-1 potency was 25 times greater in equine pulmonary artery than in equine bronchus (concentration of ET-1 producing 50% of maximal contraction [EC50] = 5.6 10-9 mol/l and 2.2 10-8 mol/l, respectively). In pulmonary artery, ET-1 induced contractions were significantly inhibited by the ETA receptor antagonist BQ123 (1 μmol/l; dose-response curve to ET-1 was shifted to the right by 5.4-fold), but not by the ETB antagonist BQ788. In bronchus, dose-responses curves to ET-1 were shifted to the right by BQ123 (1 μmol/l; 2.5-fold), but not by BQ788 (1 μmol/l). In the presence of both antagonists, the dose-response curve to ET-1 was shifted to the right by 4.5-fold. Conclusions: These functional studies demonstrate that ET-1 is a potent spasmogen of equine third generation pulmonary artery and bronchus, and that contractions are mediated via ETA receptors in the former and both ETA and ETB receptors in the latter. Potential clinical relevance: Endothelin receptor antagonists may have potential for treating equine pulmonary hypertension or bronchoconstriction. [less ▲]

There is a complex functional organization of the central auditory system from the brainstem to primary and associative auditory cortices. Functional neuroimaging has been used to visualize and confirm the spatial distribution of brain activation in temporal areas for the processing of simple acoustic stimuli. Brain activity is much more complex for words, and different networks can be recruited when phonological, lexical and semantic levels of processing are engaged. [less ▲]

An acute respiratory attack with bronchospasm is associated with excessive stimulation of the parasympathic nervous system. It may be reduced by administration of anticholinergic agents. Atropine and ipratropium bromide have been tested. This study is to evaluate the efficacy of the synthetic antimuscarinic compound glycopyrrolate as a bronchodilator in horses. Respiratory crisis was induced in seven allergic horses by exposure to natural allergens. Prior to the study, it was established that the attack could be stopped using intravenous atropine sulphate. Pulmonary function tests (ventilation and arterial blood gas analysis) were performed on the horses before and then after aerosol administration of 1500 µg of glycopyrrolate (Robinul®). The attack was characterised by an increase in total pulmonary resis¬tance and maximum pleural pressure variation and by decreased compliance. This study demonstrates that glycopyrrolate exhibits affects that are just as rapid and effective as intravenous atropine or aerosol administration of 1200 µg dry powder Ipratropium. In addi¬tion the treatment was well tolerated and no side-effects were observed in contrast to those seen with intravenous administration of atro¬pine. Therefore this drug has an important role to play among the therapeutics available to practitioners for acute respiratory attacks in horses [less ▲]
