We compare the location of the polar cap boundary (PCB) determined using two different techniques, and use them as proxies for the open-closed field line boundary (OCB). Electron temperatures from observations of the EISCAT radar facility are used to estimate the latitude of the PCB along the meridian of the EISCAT VHF beam. The second method utilizes global images of proton aurora obtained by the IMAGE satellite FUV SI12 instrument. These methods are applied to three different intervals. In two events, the agreement between the methods is good and the mean of the difference is within the resolution of the observations. In a third event, the PCB estimated from EISCAT data is located several degrees poleward of that obtained from the IMAGE FUV SI12 instrument. Comparison of the reconnection electric field estimated from the two methods shows that high-resolution measurements both in time and space are needed to capture the variations in reconnection electric field during substorm expansion. In addition to the two techniques introduced above to determine the PCB location, we also use a search for the location of the reversal of the east-west component of the equivalent current known as the magnetic convection reversal boundary (MCRB). The MCRB from the MIRACLE magnetometer chain mainly follows the motion of the polar cap boundary during different substorm phases, but differences arise near the Harang discontinuity. [less ▲]

The performance of a Fleisch No. 5 pneumotachometer (F), and two commercial ultrasonic pneumotachometers, the BRDL (B) and the Spiroson (S) systems were compared in respect to their use for determination of ventilatory parameters at rest and during lobeline-induced hyperpnoea. Five clinically healthy Thoroughbred horses were tested with the three pneumotachometers in random order. Respiratory airflow, respired gas concentrations, oesophageal pressures, pressures within the mask systems and arterial blood gases were determined before and during lobeline-induced hyperpnoea. Because measured peak expiratory airflow rates exceeded the stated linear range of the Fleisch pneumotachometer ( approximately +/- 25 l s(-1)) differential pressure-flow curves were determined in vitro over the range of flows recorded in vivo. Expired flows greater than the linear range were corrected according to the derived regression equation. No differences in any of the measured variables among the three systems were present at rest. At peak ventilation of lobeline-induced hyperpnoea mask pressures [Delta P(mask)(mean (SEM)): F: 9.6 (2.8) cm H(2)O, B: 0.8 (0.4) cm H(2)O, S: 1.4 (0.8) cm H(2)O] and end tidal carbon dioxide [ ET CO(2)(mean (SEM)): F: 2. 6 (0.1)%, B: 2.1 (0.2)%, S: 2.1 (0.1)%] were significantly higher in system F. Despite a tendency for respiratory frequency and peak inspired and expired flows, to be lower with system F, no significant differences in the measurements of ventilatory mechanics were detected. In conclusion, the ultrasonic flowmeters pose significantly lower resistive loads onto the respiratory system during ventilation above resting levels than Fleisch No 5 pneumotachometers. However, at the flowrates achieved during lobeline-induced hyperpnoea an in vitro calibration of the differential pressure-flow relationship allows correction for expiratory alinearity in system F. In addition, the performance of the Spiroson flowmeter is accurate in determining ventilatory mechanics at rest and during lobeline-induced hyperpnoea. [less ▲]

The concept of the ‘active school’ emerged a decade ago as the role with increasing recognition of the role of schools in the promotion of physical activity. The purpose of this paper is to present the findings of a study which, drawing on Cale’s ‘Active School’ model, aimed to compare the nature and extent of physical activity promotion in secondary schools in three European regions. In so doing, it aimed to establish whether there were cultural differences in the strategies and approaches adopted by schools. [less ▲]

Introduction Platelet growth factors are known for their ability to speed up tissue healing (bone, skin, tendons, muscle). Various techniques make it possible to collect this platelet-rich plasma or PRP. Methods This study compares the platelet concentrations obtained from five patients using GPS™ III, which has recently come onto the market, with those obtained using GPS™ II. Results and conclusion We obtain a platelet concentration that is six to nine times greater with GPS ™ II and GPS™ III, but there is no significant difference between the concentrations of PRP obtained with the two systems.

To assess the number of anti-osteoporosis treatments that would be reimbursed by the Belgian social security if either FRAX or the current criteria were used to determine access to reimbursement. This is a retrospective study based on data from 1,000 women randomly selected from an outpatient hospital specialized in bone metabolism in Belgium. Proportions of potentially refunded treatments between FRAX and current criteria were compared. Out of the 1,000 women files, 890 have sufficient information to assess FRAX . In Belgium, current criteria include a bone mineral density (BMD) T score below -2.5 at the lumbar spine, the femoral neck or the total hip and/or at least a prevalent vertebral fracture. Using these criteria, 167 women (18.8 %) would have access to reimbursement. Using the criteria based on the validated Belgian FRAX tool, only 116 women (13.0 %) would have access to reimbursement, meaning that access to reimbursement based on FRAX criteria would reduce by 30 % the anti-osteoporosis drug expenses covered by the national social security. Interestingly, only 65 women out of the 116 (56.0 %) selected with the FRAX criteria were also selected with the current criteria of the national social security. A substantial proportion of individuals that would potentially receive a reimbursement for their treatment using the FRAX criteria do not have access to any refund for their treatment with the current criteria. Since patients identified with the FRAX tool are those with the highest risk profile for future fractures, reappraisals of treatment reimbursement guidelines are expected in Belgium. [less ▲]

The objective of this study was to compare the repeatability of echocardiographic measurements obtained from different echocardiographic modes and views in healthy adult equids of various sizes, breeds and thorax shapes. Ten, free of cardiac disease, equids (body weight: 120 to 662 kg; age: 1 to 26 years) from various breeds were used in this study. Each animal was submitted to a standardized echocardiographic and Doppler protocol 3 times at 1 day interval. This protocol included the measurements of left and right ventricular, aortic, pulmonary, and left atrial parameters obtained from different views using the bidimensional (2D) or the motion (M) modes, and the measurement of several parameters of blood flow obtained from the pulsed wave Doppler mode. Repeatability of each measurement was estimated on the basis of the residual variance using a linear model and the coefficient of variation of repeated measurements. A two by two comparison of the repeatability of measurements performed in different views was performed using the residual variances in a variance ratio F test. Results showed that repeatability of echocardiographic or Doppler measurements in equids of various sizes, breeds and thorax shapes are comparable to previously reported results in thoroughbred and standardbred horses. Left ventricular morphologic parameters showed a good repeatability in the classic M-mode right parasternal short axis (Sax) view at the level of the chordae tendinae, but the 2D-mode right parasternal long axis (LAx) four- chambers view appeared to offer an interesting alternative to measure them. This latter view also allowed obtaining the mostre repeatable measurement of right ventricular internal diameter. The left atrial diameter was maximal and most repeatable in the 2D-mode left parasternal long axisLAx four- chambers angled view, and the repeatability of the aortic diameter was best in the 2D-mode right parasternal long axisLAx five-chambers view. Finally, aortic systolic time intervals were more repeatable when measured from the Doppler mode as compared to the M-mode. ThusIn conclusion, best repeatability of echocardiographic measurements in horses could be optimized following an echocardiographicthe following protocol in equids: 1-M-mode right parasternal short axis view at the level of chordae tendinae, to measure left ventricular morphologic parameters, and 2D-mode right parasternal long axis four-chamber as an alternative view. 2-2D-mode right parasternal long axis five-chambersre, to measure the aortic diameter. 3-2D-mode left parasternal long axis four-chambersre angled view, to measure the left atrial diameter.

The objective of this study was to compare the sedative and peripheral hemodynamic effects of acepromazine (ACP) and promethazine (PTZ) in the standing healthy horse. Nine healthy Warmblood horses randomly received either intravenous ACP at 0.1 mg/kg or PTZ at 0.1, 0.2, and 0.3 mg/kg. A sedation score based on clinical examination was recorded, and systolic arterial blood pressure was noninvasively evaluated using a Doppler flow detector at the tail, just before and every 15 minutes until 60 minutes after drug injection. Hemodynamics of the median artery of the left forelimb was studied using Doppler ultrasonography just before and 45 minutes after injection of the drug, which allowed calculation of surface (SURF), diameter (DIAM), and circumference (CIRC) of the vessel and peak systolic velocity (PSV), end diastolic velocity (EDV), mean velocity (MV), volumetric flow (VF), and resistivity index (RI) of the blood flow. Regardless of the dose used, PTZ had lesser sedative and hypotensive effects than ACP at 0.1 mg/kg and did not induce significant variations in SURF, DIAM, CIRC, PSV, EDV, MV, VF, and RI of the studied standing horses. Conversely, the vasodilatory properties of ACP were illustrated by a significant increase in SURF, DIAM, CIRC, PSV, EDV, MV, and VF and a significant reduction of the RI. Unlike ACP, PTZ did not induce alterations on the morphology of the Doppler waveform. PTZ appears to have less sedative and peripheral vasodilator effects than ACP, thus it could be safer than ACP in patients suffering from hypotension. [less ▲]

Background: The recent introduction of Sensititre YeastOne, a colorimetric microdilution method that includes new antifungal agents has opened the field to MIC’s determination by an easy-to-perform method. The aim of this study was to compare this test with the NCCLS M27-A protocol and with Fungitest, a current routine method for yeasts susceptibility testing. Methods: Sensititre YeastOne method (Trek diagnostic), and the NCCLS M27-A2 were performed on 300 yeasts clinical isolates distributed as follow: 125 C. albicans, 273 non-albicans species. Four antifungal agents were tested by the reference method: amphotericine B (AmB), fluconazole (FZ), itraconazole (ITZ), and voriconazole (VOR). The reading of the Sensititre and NCCLS results was visually performed after 24 and 48 h respectively. The Fungitest (Biorad) method was applied on 121 among the 300 isolates and the reading was made after 24 to 48 h incubation time according to the positive control growth. Results: By the NCCLS method, the MICs50/MICs90 (µg/ml) were as follows: 1/2 (AmB); 16/64 (FZ); 0.25/4 (ITZ) and 0.125/2 (VOR). Sensititre vs. NCCLS: The overall agreement within 2 dilutions for AmB, FZ, ITZ and VOR was respectively 54, 82, 80 and 78%. The MICs50/MICs90 were in absolute concordance for VOR by both techniques. Very major errors (%) were recorded as follows: 0.01/0 (AmB with a MIC ≥ 4/8µg/ml for resistant strains respectively), 1.6 (FZ), 3.6 (ITZ) and 2.3 (VOR with a MIC ≥ 8µg/ml for resistant strains). Fungitest vs. NCCLS: The agreement between both methods including minor discrepancies was 98% (AmB), 88% (FZ) and 98% (ITZ). Following the breakpoints given by the manufacturer, very major errors were 6.3% for FZ, 0.03% for ITZ and none for AmB. Conclusions: Sensititre is a convenient alternative to the NCCLS method for yeast susceptibility testing. Fungitest in spite of good correlations must change the breakpoints and include new antifungal agents to be competitive. [less ▲]
