DBP reduction in the last 6 h of the once-daily dosing interval and 24-h mean DBP control when a dose is missed are significantly superior with telmisartan than with valsartan. Thus, telmisartan due to its longer half -life offers more sustained BP control, especially at the end of the dosing period and provides sustained efficacy in poorly compliant patients. [less ▲]

In electric power system instabilities such as subsynchronous resonance or interarea oscillations, two complex modes can approach each other in frequency and then interact by changing damping so that one of the modes becomes unstable. Selecting changes in parameters to minimize this interaction is difficult by trial and error. By analyzing the interaction as a perturbation of a weak resonance, we calculate sensitivities that indicate the parameters to be changed to minimize the interaction and stabilize the system. The method is illustrated with a simple example of two coupled linear oscillators. The use of sensitivity methods to change the type of the interaction is also demonstrated. [less ▲]

Hypothesis / aims of study The aim of this study was to prospectively evaluate the efficacy of the TVT-O inside-out procedure for the treatment of female stress urinary incontinence (SUI). Study design, materials and methods From March 2003 through September 2003, 53 patients with clinical evidence of SUI participated in this prospective clinical trial. Preoperative evaluation included complete history, physical examination, multichannel urodynamics, urine analysis, and cystoscopy. None of the patients presented the following exclusion criteria: post-void residual volume (PVR) ≥ 100 cc, detrusor overactivity or acontractility, contraindication to anesthesia, pregnancy, neurological pathology, or active urinary or vaginal infection. All patients met the following inclusion criteria: age > 25 and < 85 years, clinically demonstrated SUI, positive Ulmsten test, and maximum cystometric capacity ≥ 300 mL. In all patients, a sub-urethral tape (Gynecare®) was inserted by one single surgeon via an inside-out transobturator approach (TVT-O), as previously described (1). Evaluation of SUI, urgency/urge incontinence, daytime urinary frequency/nocturia, and lower urinary tract symptoms (LUTS) suggestive of bladder outlet obstruction/retention was carried out using the Measurement of Urinary Handicap scale questionnaire (2). The importance of urinary incontinence was assessed with a visual analog scale graded from 0 to 10. Quality of life (QoL) assessment was performed using the validated Ditrovie self-administered questionnaire. Outpatient follow-up was perfomed at 1 and 6 months, and every 6 months thereafter. Follow-up evaluation included physical examination with a stress test, uroflowmetry, PVR, and symptom, visual analog, and QoL scales scoring. Cure was defined as no leakage based on both symptom scale scoring and physical examination. Improvement was defined as at least a 50% decrease in symptoms based on the questionnaire’s evaluation. Chart review was conducted by a physician not associated with the surgical procedure. The specific protocol used in this study was approved by the Medical Ethics committee of our Institution. All patients had given their written informed consent. Methods, defintions,and units conform to the standards recommended by the ICS. Results Mean age of the patients was 61.2 years (36 to 80). Of the 53 patients, 20 had undergone previous pelvic surgery. Forty-eight patients suffered from SUI. Five patients did not complain of SUI but had clinical evidence of SUI after reduction of pelvic organ prolapse (POP) during vaginal examination. The TVT-O procedure was associated with POP cure (performed before TVT-O) in 12 patients. Maximal urethral closure pressure was < 30 cm H20 in 6 patients. Follow-up time was ≥ 6 months in all women (max = 12.5; mean = 8). A total of 33 and 20 women received spinal and general anesthesia, respectively. Intraoperative blood loss was < 100 cc in all cases. No vaginal wall, urethral, or bladder perforation was encountered. No hematoma, neurological complication, fistula, vaginal or urethral erosion, or tape rejection was observed. Some patients reported pain symptoms, directly after the procedure, mainly located in the thigh regions (either uni- or bilaterally). Pain was always mild, never requiring opioid antalgics. No patient complained of persistent pain; indeed, pain had completely vanished within the first post-operative month in all cases. At the latest follow-up visit, PVR was < 100 cc and max flow rate was ≥ 10 mL/sec in 49 (92.4%) and 39 (73.6%) patients, respectively. One patient underwent an immediate tape release procedure for complete retention 2 days after TVT-O. Thereafter, the patient had no PVR and was completely dry. The tape was sectioned in 2 patients for chronic retention and/or urgency associated with bladder outlet obstruction, 4 and 7 months after the operation. Based on the SUI questionnaire evaluation and physical examination, 50 (94.3%) patients were cured. SUI symptoms had improved in 1 patient and had not changed in another. One patient with POP not complaining of SUI preoperatively (but with clinically demonstrated SUI following POP reduction) developed SUI after POP cure associated with TVT-O. Analysis of the urgency questionnaire’s results revealed that among the 53 patients, 32 did not complain of any urgency before the operation. Of these 32 patients, 3 patients developed de novo urgency, with one of them requiring tape sectioning because of obstruction-associated urge incontinence. Among the 21 patients with preoperative urge symptoms, 15 of them reported disappearance of urgency after the procedure. Urge symptoms were unchanged in the remaining 6 patients. Daytime frequency/nocturia symptoms scale scoring showed that 4 patients had a worsening of these symptoms while all other patients were either improved or unchanged. LUTS suggestive of bladder outlet obstruction/retention appeared or worsened in 3 patients, amongst which the 2 patients who required tape sectioning. These symptoms were unchanged or decreased (mainly in patients with associated POP cure) in all other patients. Analysis of the urinary incontinence visual analog and QoL scale scores demonstrated that the majority of patients reported disappearance of urinary leakage together with significant improvement of their QoL (Figures 1 and 2). Interpretation of results As already suggested by the results of a recent feasibility study (1), TVT-O appears to be associated with a minimal risk of peri-operative complications. Indeed, in our present prospective study, no injury to the bladder, vagina, or urethra was encountered and we have not observed any vascular, digestive or neurological complication. Our data suggest that TVT-O is associated with high objective and subjective SUI cure rates and a low incidence of post-operative complications. Longer follow-up times are required to determine the long-term efficacy of TVT-O. Concluding message The short term results of this prospective study suggest that TVT-O is a safe and efficient surgical procedure for the treatment of female SUI. References 1.

Within the frame of the NDSC, the total vertical column abundances of HCl and ClONO2, by far the two most important inorganic chlorine reservoirs at northern mid-latitudes, have been further monitored above the Jungfraujoch station (Swiss Alps, 46.5ºN, 8.0ºE, 3580m a.s.l.), by analyzing infrared solar absorption spectra recorded with very high-resolution Fourier spectrometers. The mean temporal evolution of the sum of their monthly mean abundance time series indicates that the total stratospheric inorganic chlorine loading (Cly) has decreased slowly (-0.7+/-0.3%/yr, 1-sigma) since it peaked in late 1996, at the limit of being statistically significant at the 2-sigma level. Comparison with model calculations and with the evolution of surface total organic chlorine will also be discussed. [less ▲]

Bovine pregnancy-associated glycoproteins (bPAGs) are secreted by binucleate cells of the placenta and can be assayed in maternal plasma as indicators of pregnancy and markers for the functional status of the trophoblast. The concentrations of PAGs vary differentially during the peri-implantation period. Large offspring syndrome (LOS) and abnormal placentation have been associated in cloned fetuses with abnormally increased pregnancy-specific protein 60 (PSP60). The aim of this study was to investigate the evolution of plasma levels of PAGs measured by the use of three different RIA systems in heifers after transfer of somatic cloned embryos and to compare that to plasma levels of control recipients during early pregnancy to distinguish which ones vary differentially. Cloned embryos were derived from nuclear transfer from fibroblasts of an adult cell line to in vitro-matured bovine oocytes according to Vignon et al. (1998 Theriogenology 49, 392). Control embryos were obtained in vitro after IVF and cultured in serum-free medium up to the blastocyst stage. By Day 7, cloned (n = 29) and control embryos (n = 10) were transferred to synchronous recipient heifers of the Normande breed (one embryo per recipient). Blood samples were taken every 2–3 days between Days 25 and 50 of pregnancy from recipients that had a positive progesterone test on Day 21, and the plasma was stored frozen until assay. Pregnancy status was monitored by repeated ultrasound scanning from Day 35 to Day 90. Concentrations of PAGs were determined by validated RIA assays for the different forms (PAGI67, PAG55+62, PAG55+59) using 3 antisera (AS 497, AS 706, AS 708, respectively) (Perenyi et al. 2002 Reprod. Domest. Anim. 37, 100–104). profiles of only the recipients that were confirmed pregnant by scanning over Day 50 (n = 18 clones, n = 4 controls) were analyzed and compared. Concentrations of PAGs measured by AS 497 and AS 706 were significantly higher in clones than in control recipients during the second month of pregnancy, indicating that the placenta of clones secreted these forms in a different manner compared to controls. Moreover, we found that concentrations of PAGs as determined with the two same antisera were higher for recipients with a cloned fetus that developed to term compared to those which had fetal loss before 3 months. For instance, using the AS 706, respective values of PAGs at Day 45 were 17.64 ± 7.59 and 10.96 ± 6.38 ng/mL for pregnancies with cloned and control fetuses, respectively, (P < 0.05) and 21.29 ± 4.77 and 12.88 ± 8.90 ng/mL in pregnancies with cloned fetuses that developed normally to term or died before 3 months of age, respectively, (P < 0.05). We conclude that our assays using two antisera could be a predictive test for fetal loss in clone pregnancies. Until now, recipients carrying cloned embryos that develop LOS during late pregnancy could not be detected by conventional assays in maternal serum or by scanning during the period of 35–50 days. This study provides a new diagnostic tool to detect them. Investigations are in progress to check the localization of these different forms of PAG in placentomes removed from recipients carrying somatic clones. [less ▲]

Studies of eukaryotic genome expression demonstrate the importance of steroid receptor coactivators in mediating efficient gene transcription. Little is know about the physiological role of these coactivators in vivo. We recently showed that the Steroid Receptor Coactivator SRC-1 is densely expressed in steroid-sensitive brain areas in birds and its expression is steroid-dependent and sexually differentiated. We tested the role of SRC-1 in the activation by testosterone of male sexual behavior in quail. Daily injections of LNA antisense oligonucleotides in the third ventricle (AS group) significantly reduced the expression of male copulatory behavior in response to exogenous testosterone compared to control animals (Ctrl group) receiving the vehicle alone or scrambled LNA. Sexual behavior was restored and even enhanced within 48 hours after interruption of LNA injection (ASSC group). Western blot analysis confirmed the decrease of SRC-1 expression in AS animals and suggested an over-expression of the coactivator in ASSC animals. The effect of SRC-1 knock down on behavior was correlated with a reduced volume of the medial preoptic nucleus (POM) defined by Nissl-staining and aromatase immunohistochemistry. In addition, the amount of aromatase-immunoreactive material in POM, defined as the relative optical density of the aromatase immunoreactivity multiplied by the percentage of surface covered within the nucleus and by the total POM volume of the POM, was decreased in the AS compared to the Ctrl group, suggesting a blockade of aromatase transcription. Together, these data indicate that SRC-1 functions as a critical regulatory molecule in the brain that modulates steroid-dependent gene transcription and behavior. [less ▲]

L’analyse en composantes principales a permis de mettre en évidence des groupes de variables et de visualiser les relations qui peuvent exister entre ces variables. La première composante principale est corrélée aux variables relatives à la qualité technologique et organoleptique de la viande. Elle met en opposition le pH45 d’une part et les paramètres L*, b* et Cond45 d’autre part. La deuxième composante principale peut être considérée comme un axe de qualité microbiologique.

Glucosinolates are a class of ca. 120 secondary plant metabolites generally found in Brassicaceae. These compounds have a similar structure characterised by a common part containing a beta thioglucose coupled with a sulfonated oxim group and by a variable organic side chain constituted with alkyl, alcenyl, hydroxy-alcenyl, aryl, indolyl, sulfinyl, sulfonyl or thio residues. Present in high or low level (00 varieties) in rapeseed/canola seeds and in rapeseed/canola meals, these molecules are easily broken down during animal digestion, leading to compounds with detrimental and antinutritional characteristics. They are known to interfere with the thyroid and to damage vital organs (Fenwick et al., 1983). [less ▲]

Major challenge for semi-solid processing includes broadening the range of alloys that can be successfully thixoformed and developing alloys specifically for thixoforming. One important parameter is appropriate solidus-liquidus interval. The wider the solidification interval, the wider the processing window. This study is related to the experimental determination of this critical parameter on eight different steel compositions. This parameter was obtained using Differential Scanning Calorimetry. This technique allows to obtain the solid fraction versus temperature. The paper also presents the results of thermophysical properties determination such as thermal diffusivity, heat capacity and thermal conductivity. These properties were measured from room temperature to semi-solid state in one particular steel. The thermal diffusivity was measured using the Laser Flash method and the heat capacity using a DSC calorimeter. The thermal conductivity was obtained by calculation knowing the thermal dilatation measured with a dilatometer. All these measurements were performed for temperatures up to the liquidus. These parameters are difficult to measure but they are important to determine for the conductive heating phase of a semi-solid forming (SSM) process. [less ▲]

For five years, a postgraduate program in Educational and Training Technology has been developed by both Universities of Liège and Namur (Belgium). This program addresses already graduated adults having a training background. Depending on his/her training experience and a personnal project, the participant has the opportunity of developing different competencies profiles like: educational designer, designer and manager of training systems integrating ICT, e-tutor or trainer in e-learning environments, designer and producer of information or learning multimedia products. The plan of action articulates face-to-face and distance activities. It is based on several principles like definition and follow-up of a personal learning project, clarification of the actors’ roles, systematical use of technologies, active pedagogical methods and quality process. The authors present a series of scenarios including several types of distance activities. On the one hand, they illustrate these activities, insisting on their target goals, their meaning and usefulness, their development and their evaluation criteria. On the other hand, they discuss the organization of face-toface, blended or distance activities taking into account different sides of a learning system in order to stimulate the thought of designers and animators of such learning environments.

Les chrysomèles sont des insectes phytophages brillamment colores qui, avec plus de 32000 espèces, représentent une des familles (Chrysomelidae) les plus importantes de 1'ordre des coléoptères. Etant aposématiques, ils sont facilement repérables par des prédateurs potentiels et ont, au cours de 1'evolution, développé des mécanismes de défense chimique élaborés. La découverte de glycosides triterpéniques basés sur le squelette oléanane (comme par exemple le ligatoside B) dans les secrétions défensives de plusieurs espèces de Doryphorina (Platyphora, Desmogramma et Leptinotarsa) a soulevé le problème de leur origine biogénétique. En effet, il est bien connu que les insectes ne possèdent pas la squalène synthase, une enzyme indispensable à la formation des stéroïdes et des triterpènes pentacycliques. Des lors, une biosynthèse de novo de ce type de dériveé par les chrysomèles est peu probable. Par ailleurs, l’analyse de la plante hôte des chrysomèles a montre que la séquestration des glycosides au départ de cette plante est également exclue. Une troisième possibilité serait que 1'insecte utilise un précurseur provenant de son alimentation pour fabriquer ses substances défensives. Un tel précurseur pourrait être la la b-amyrine identifiée chez différentes plantes hôtes des chrysomèles ou 1'acide oléanolique dont la structure de base se retrouve au niveau des triterpènes défensifs. Enfin l’analyse des plantes hôtes a montré que celles-ci contiennent a la fois de la b-amyrine et de l’a-amyrine dans un rapport 1,76/1. Cependant, aucun glycoside triterpénique basé sur le squelette ursane n'a été isolé jusqu'à présent chez les chrysomèles, ce qui suggère un mécanisme de transport sélectif en faveur de la b-amyrine . Dans le cadre de ce travail, nous présenterons les synthèses d'a-amyrine, de b-amyrine et d'acide oléanolique trideutériés, ainsi que les résultats d'incorporation des deux premiers précurseurs chez Platyphora kollari.
