1Diagnostic techniques for photonic materials based on Raman and Brillouin spectroscopies显示文摘The elastic and vibrational properties of a material,bulk or planar waveguide,are studied by Brillouin and Raman spectroscopy to follow the process of nanocrystals growth in glass-ceramics. The nanoparticles cause the appearance,in the low fre-quency Raman spectrum,of characteristic peaks,whose position depends on the size of the crystals. At the same time,sharp crystal peaks,due to optical phonons,appear in the Raman spectra,allowing the determination of the nucleated phase,and a frequency shift of the Brillouin peaks is observed.M.

2食管静脉曲张治疗:内镜下硬化和EUS引导下硬化治疗食管侧支静脉的随机对照研究显示文摘Background: Endoscopic sclerotherapy (ES) and band ligation are standard treatments for esophageal varices. Unfortunately, recurrence is common and seems to be related to esophageal collateral vessels, easily identified by EUS. Eradication of these vessels might lead to a more durable therapeutic effect. Objective: To compare ES with EUS-guided sclerotherapy of collateral vessels (EUS-ES). Design: Randomized controlled trial. Setting: Endoscopy Unit, Division of Gastroenterology. Universidade Federal de S o Paulo, S o Paulo, Brazil. Patients and Interventions: Fifty cirrhotic patientswith esophageal varices were randomized into 2 groups: ES (n = 25) and EUS-ES (n = 25). EUS-ES was targeted at collateral veins. Patients were followed-up for at least 6 months after eradication. Main Outcome Measurements: Efficacy in eradication, complications, and recurrence of varices. Results: Varices were eradicated in 48 patients who adhered to the study protocol. The mean (SD) number of sessions until eradication was 4.3 (1.5) for the ES group and 4.1 (1.2) for the EUS-ES group. In ES group, 4 patients had mild bleeding. In EUS-ES group, 4 patients had pain. The mean (SD) length of the follow-up period was 22.6 (6.9) months for the ES group and 24.9 (8.1) months for the EUS-ES group. Recurrence was seen in 4 patients after ES and in 2 after EUS-ES (P = .32). The presence of collateral vessels was associated with recurrence (P = .003). Conclusion: EUS-ES is as safe and effective as ES in variceal eradication. Recurrence tends to be less frequent and occurs later. Persistence of esophageal collateral vessels after sclerotherapy is a risk factor for recurrence.Andrade De Paulo G. Ardengh J. C. Nakao F. S.

3不同观察者间在多巴酚丁胺负荷磁共振成像时识别诱发性左心室室壁运动异常的变异性显示文摘Aims: To determine the interobserver variability for identifying inducible left ventricular(LV)wall motion abnormalities during high-dose dobutamine/atropine stress cardiovascular magnetic resonance(DSMR). Methods and results: Four readers from various institutions were supplied with the image data from 150 consecutive DSMR examinations and asked to grade wall motion and image quality throughout graded doses of dobutamine infusion administered to achieve 85%of the maximum age-predicted heart rate. Inducible ischaemia was identified if more than one segment demonstrated a new or worsening LV wall motion abnormality, and significant stenosis was defined as ≥50%luminal diameter reduction by quantitative contrast coronary angiography. Seventy-seven patients(51%) had luminal narrowings ≥50%. Diagnostic performance(sensitivity, specificity, diagnostic accuracy) of all readers was 78.2, 87.0 and 82.5%. Disagreement between two readers occurred in every seventh examination. Agreement on the presence or absence of inducible wall motion abnormalities was moderate(mean kappa value 0.59, range 0.52-0.76). Diagnostic performance and disagreement were independent of the presence of luminal narrowings ≥50%or the number of diseased coronary vessels. Image quality was regarded excellent in 89.3%of standard views. Conclusion: In the setting of multiple observers from different institutions performing a diagnostic reading of DSMR examinations carried out at a single centre, the interobserver variability was low for identifying inducible LV wall motion abnormalities indicative of coronary arterial luminal narrowings ≥50%.Paetsch I.

8Er^(3+)-activated silica inverse opals synthesized by the solgel method显示文摘We present the details of the sol-gel processing used to realize inverse silica opal,where the silica was activated with 0.3 mol% of Er3+ ions. The template(direct opal) was obtained assembling polystyrene spheres of the dimensions of 260 nm by means of a vertical deposition technique. The Er3+-activated silica inverse opal was obtained infiltrating,into the void of the template,the silica sol doped with Er3+ ions and subsequently removing the polystyrene spheres by means of calcinations. Scanning electron microscope showed that the inverse opals possess a fcc structure with a air hollows of about 210 nm and a photonic band gap,in the visible range,was observed from reflectance measurements. Spectroscopic properties of Er3+-activated silica inverse opal were investigated by luminescence spectroscopy,where,upon excitation at 514.5 nm,an emission of 4I13/2 → 4I15/2 of Er3+ ions transition with a 21 nm bandwidth was observed. Moreover the 4I13/2 level decay curve presents a single-exponential profile,with a measured lifetime of 18 ms,corresponding a high quantum efficiency of the system.A. Chiappini C.Armellini A.
