Abstract
BACKGROUND Pain drawings (PD) are frequently used in research to illustrate the pain response to pain provocation tests. However, there is a lack of data on the reliability in defining the extent and location of pain. We investigated the test-retest reliability in reporting an acute painful sensation induced by a pain provocation test using a novel approach for PD acquisition and analysis in healthy volunteers. METHODS Forty healthy volunteers participated. Each participant underwent 2 upper limb neurodynamic tests 1 (ULNT1), once to the point of pain onset (PO) and once until the point of submaximal pain (SP). After each ULNT1, participants completed 2 consecutive PD with an interval of 1 minute. Custom software was used to quantify the pain extent and analyze the pain overlap. The test-retest reliability of pain extent was examined using Intraclass Correlation Coefficient (ICC 2,1 ) and Bland-Altman plots. Pain location reliability was examined using the Jaccard similarity coefficient (JSC). RESULTS The ICC values for PO and SP were 0.98 (95% CI: 0.96-0.99) and 0.97 (95% CI: 0.95-0.98), respectively. The mean difference and 95% limits of agreement (± 1.96 SD) in the Bland-Altman plots were 14 pixels (-1080;1110) for PO, and 145 (-1610;1900) for SP. The median JSCs (Q1;Q3) were 0.73 (0.64;0.80) for PO and 0.76 (0.65;0.79) for SP. CONCLUSIONS Pain drawings is a reliable instrument to investigate pain extent and pain location in healthy individuals experiencing an acute painful sensation induced by a pain provocation test.

Abstract
BACKGROUND The Dutch Walking Stairs, Walking Ability and Rising and Sitting Questionnaires are three validated instruments to measure physical activity and limitations in daily living in patients with lower extremity disorders living at home of which no German equivalents are available. Our scope was to translate the Walking Stairs, Walking Ability and Rising and Sitting Questionnaires into German and to verify its concurrent validity in the two domains pain and activities in daily living by comparing them with the corresponding measures on the Visual Analogue Scale. METHODS We translated the Walking Stairs, Walking Ability and Rising and Sitting Questionnaires according to published guidelines. Demographic data and validity were assessed in 52 consecutive patients with Complex Regional Pain Syndrome 1 of the lower extremity. Information on age, duration of symptoms, type of Complex Regional Pain Syndrome 1 and type of initiating event were obtained. We assessed the concurrent validity in the two domains pain and activities in daily living by comparing them with the corresponding measures on the Visual Analogue Scale. RESULTS We found that variability in the German Walking Stairs, Walking Ability and Rising and Sitting Questionnaires was largely explained by measures of pain and activities in daily living on the Visual Analogue Scale. CONCLUSION Our study shows that the domains pain and activities in daily living are properly represented in the German versions of the Walking Stairs, Walking Ability and Raising and Sitting Questionnaires. We would like to propagate their use in clinical practice and research alike.

Abstract
BACKGROUND Patients suffering from Complex Regional Pain Syndrome commonly complain of substantial limitations in their activities of daily living. The Radboud Skills Questionnaire measures alterations in the level of disability of patients with Complex Regional Pain Syndrome, but this instrument is currently not available in German. The goals of our study were to translate the Dutch Radboud Skills Questionnaire into German and to assess its external criterion validity with the German version of the Disabilities of the Arm, Shoulder and Hand Questionnaire. METHODS We translated the Radboud Skills Questionnaire according to published guidelines. Demographic data and validity were assessed in 57 consecutive patients with Complex Regional Pain Syndrome 1 of the upper extremity. Information on age, duration of symptoms, type of Complex Regional Pain Syndrome 1 and type of initiating event was obtained. We assessed the external criterion validity by comparing the German Radboud Skills Questionnaire and the German Disabilities of the Arm, Shoulder and Hand Questionnaire and calculated the prediction intervals. RESULTS Score values ranged from 55.4 +/- 22.0 for the Disabilities of the Arm, Shoulder and Hand Questionnaire score and 140.1 +/- 39.2 for the Radboud Skills Questionnaire. We found a high correlation between the Radboud Skills Questionnaire and the Disabilities of the Arm, Shoulder and Hand Questionnaire (R2 = 0.83). CONCLUSION This validation of the Radboud Skills Questionnaire demonstrates that this German version is a simple and accurate instrument to assess and quantify disabilities of patients suffering from Complex Regional Pain Syndrome 1 of the upper extremity for clinical and research purposes.

Abstract
We have observed the condensation of a mixture of gamma-glycidoxypropylmethyldiethoxysilane and 3-aminopropyltriethoxysilane in dilute aqueous solutions. NMR and IR spectroscopy have allowed to follow the condensation process in the mixture, which is noticeably enhanced and proceeds faster than for each silane on its own. Cross-condensation between the two silanes was evidenced. When the hydrophilic aminosilane is in excess, the condensation, as evidenced by dynamic light scattering, proceeds toward gel formation because the oligomers formed are essentially hydrophilic. When the more hydrophobic epoxysilane is in excess, oligomer growth proceeds slowly and results in a destabilization of the solution: due to their hydrophobic character, the oligomers formed coalesce suddenly into 200-nm-diameter aggregates. Coatings deposited from such solutions with high epoxysilane content can be used to strengthen glass. We show that the progress of condensation in solution results in a wetting transition during deposition of the silane film on glass by dip coating. The production of increasingly hydrophobic oligomers as the reaction time increases results in adsorption of more hydrophobic aggregates at the surface, which eventually leads to dewetting of the film: in the absence of film, glass strengthening disappears.

Abstract
The use of plates for the treatment of fractures can affect craniofacial bone development. This study investigated the effect of bioabsorbable plates and titanium microscrews on the growth of the craniofacial skeleton of rabbits (Oryctolagus cuniculus), in the neonatal period. A LactoSorb plate and PROMM titanium microscrews were positioned across the coronal suture in animals in the study group. In the control group, only PROMM titanium microscrews were attached to the cranium. Anteroposterior linear measurements were obtained using 3 different gauging devices: digital precision caliper, EKG caliper and nylon string. Frontal-nasal (FN) distances were statistically different between the left and right side when the digital caliper (P<or=0.01), EKG caliper (P<or=0.01) and nylon string (P<or=0.05) were used. Mean right-side FN distances in the control and study groups were significantly different (P<or=0.05) when measured with the EKG caliper. Normal neonatal craniofacial growth of rabbits was affected by the use of bioabsorbable plates in this study. Further studies should be conducted to investigate whether these plates affect growth in human beings.

Abstract
INTRODUCTION The pharmacist plays an essential role in the management of the asthmatic patients on account of their frequent visits to the pharmacy to obtain their medication. METHODS In order to evaluate the practice and knowledge of asthma among the pharmacists of the department of Bas-Rhin, 120 pharmacists were selected at random to reply to a standardised questionnaire. RESULTS The 86 pharmacists who replied to the questionnaire had a good general understanding of asthma and its treatment. However, only 26.4% knew all the criteria of the severity of an attack of asthma. Among the 57 pharmacists who gave a demonstration of the use of inhaler devices, 16.3% showed all the steps in the use of a metered dose aerosol. These results are comparable to those of non-specialist doctors and nurses in whom poor techniques were found in 63-100% and 65-96% respectively. The mean scores of the pharmacists were 10.5/12 (+/- 1.2) steps for metered dose aerosols, 10.4/11 (+/- 1.0) for the Tubuhaler, 9.3/12 (+/- 1.7) for the Autohaler and 8.1/9 (+/- 0.9) for the Volumatic spacer. The asthmatic patient's main expectation of the pharmacist concerned the use of the prescribed systems (87.2%), underlining the lack of information received by the patient at the time of prescription. CONCLUSIONS An improvement in the knowledge of the signs of severity of asthma and the use of inhaled devices could usefully be one of the objectives in the training of a dispensing pharmacist.

Abstract
The orientation of DNA induced by electrophoretic transport in agarose gel has been studied by optical birefringence. From its field-free decay, it is clearly demonstrated that the degree of orientation results from two processes: alignment along the electric field (stretching of the end-to-end vector) and elongation of the primitive path in the gel (overstretching). Separation of the two contributions allows the experimental determination of the effective charge per base pair, the gel pore size seen by the reptating molecule, the reptation time, the degree of overstretching and the mean relaxation time of the overstretching. Their field and DNA length dependences compare well with theoretical predictions. Similarly, the time at which overstretching presents an overshoot in the rise of the orientation follows closely the predictions of a model based on the evolution of J-shaped conformations. The recovery of such conformations is studied by a sequence of two pulses with variable delay time. The use of directly measured or extrapolated characteristic times and fields in the design of efficient pulse schemes for pulsed-field gel electrophoresis is emphasized.

Abstract
The effects of the two enantiomers of berbine (5,6,13,13a-tetrahydro-8H-dibenzo[a,g]quinolizine) and of derivatives obtained by introducing various substitutions on aromatic rings were investigated on alpha 1- or alpha 2-adrenoceptor subtypes. Binding studies carried out on rat cerebral cortex membranes using [3H]prazosin or [3H]yohimbine showed that the affinities of the (+) and (-)enantiomers for alpha 1 and alpha 2 binding sites were different and were differently modified by substitutions added to the berbine nucleus, leading to alpha 1- and alpha 2-selective compounds. Experiments performed on the isolated rat aorta and in pithed rats in vivo demonstrated the alpha-blocking property of berbine derivatives and confirmed the stereoselectivity of the effects of the (+) and (-)enantiomers on alpha 1- and alpha 2-adrenoceptor subtypes.

Abstract
Experiments were designed to investigate further the alterations in calcium metabolism caused by inaktin, a thiobarbiturate that impairs parathyroid hormone action in rats (1981). Treatment with an anesthetic dose of inaktin induced a drop in serum calcium without any variation in immunoreactive parathyroid hormone serum level and slowed body calcium turnover as studied with 45Ca, but was without effect on blood pH or partial pressures of oxygen and carbon dioxide. In contrast, calcium metabolism in rats was unchanged after treatment with an anesthetic dose of pentothal, another thiobarbiturate anesthetic. The effect of inaktin on body calcium turnover was dose-dependent and significant even at non-anesthetic levels. A marked slowing of the fast phenomena accounting for the initial dilution of the tracer in the animal was observed, accompanied by a corresponding decrease in rapid 45Ca uptake into bone, but not other tissues. These results show that inaktin slows calcium turnover, especially the fast renewal of calcium in bone. These effects were not correlated with anesthesia or immobilization, and we suggest that inaktin-induced changes in calcium metabolism involve an impairment of hypocalcemia-induced parathyroid hormone secretion, in addition to the impairment of parathyroid hormone effects previously reported. Furthermore, the present findings suggest that inaktin might be a useful tool for investigation of the rapid mobilization of bone calcium, which is as yet not well understood.

Abstract
The activity of the alpha-adrenoceptor antagonist nicergoline, a molecule composed of two constituent parts, ergoline and bromonicotinic acid, was investigated in the rat isolated aorta. Nicergoline (10 nM-0.1 microM) displaced concentration-effect curves elicited by noradrenaline and phenylephrine to the right and inhibited maximal responses elicited by both alpha-adrenoceptor agonists without significantly affecting prostaglandin F2 alpha-induced contractions. Higher concentrations of nicergoline (1 microM-50 microM) displaced to the right the concentration-effect curves elicited by calcium in a depolarizing medium. This calcium antagonist activity was not shared by either of the constituent parts. Nicergoline 100 microM abolished the 45Ca influx induced into rat aorta by 100 mM K+-containing physiological solution. The selectivity of nicergoline for alpha 1-adrenoceptors seen in binding experiments also depends on the presence of the bromonicotinic moiety of the molecule. It is concluded that nicergoline, but not its substituent parts, displays both alpha 1-adrenoceptor and calcium antagonism. The latter property may account for some of the observed effects of this compound.

Abstract
The variations of plasma cyclic AMP concentration caused by propranolol and isoproterenol were studied in order to investigate endogenous stimulation and responsiveness of the beta-adrenoceptor-cyclic AMP system in vivo, in 7 and 18 week old unanaesthetized male SHR and WKY. In both age groups, the basal cyclic AMP level was higher in SHR than in controls but was significantly reduced to a comparable value in the two strains after intraperitoneal injection of 2.5 mg X kg-1 propranolol, a dose which markedly depressed or even abolished the effect of isoproterenol. Cumulative dose-response curves of plasma cyclic AMP concentration obtained in another group of rats after successive subcutaneous injections of isoproterenol showed that the ED50 value of this drug was higher in SHR than in WKY and increased in a parallel manner in the two strains between 7 and 18 weeks of age (respectively from 0.21 +/- 0.01 to 0.34 +/- 0.02 mumol X kg-1 in WKY and from 0.32 +/- 0.02 to 0.52 +/- 0.03 mumol X kg-1 in SHR). At the same time blood pressure increased much less markedly in WKY (from 115 +/- 4 to 119 +/- 2 mm Hg) than in SHR (from 134 +/- 3 to 179 +/- 3 mm Hg). Altogether these results show that endogenous beta-adrenergic stimulation of the cyclic AMP system was higher in SHR of both ages in spite of a diminished responsiveness of this system to exogenous isoproterenol.

Abstract
A large transitory efflux of 86Rb was induced by concentrations of phenylephrine (10(-6) and 10(-4)M) or clonidine (10(-4)M) which were able to produce phasic contraction. By contrast, a lower concentration of clonidine (10(-6) M), which could only induce a slower (tonic) contraction, only produced a weak but sustained 86Rb efflux. These results show qualitative and quantitative differences in the effects of the two alpha-agonists. They further support the view that phasic and tonic alpha-adrenergic responses may be related to different mechanisms.

Abstract
The mechanism by which inaktin, a thiobarbiturate, promotes a moderate drop in serum calcium has been investigated. The effect was cancelled in hypocalcemic parathyroidectomized rats. On the other hand inaktin antagonized the serum calcium raising effects of parathyroid extract in these animals. In rats wit intact parathyroid glands inaktin caused a two-fold increase in urinary calcium excretion and a marked decrease in body and bone calcium turnover (measured with 45 Ca). These results support the view that inaktin impairs the parathyroid hormone effects on calcium metabolism.
