3Silicon and silicon nitride photonic circuits for spectroscopic sensing on-a-chip [Invited]显示文摘There is a rapidly growing demand to use silicon and silicon nitride(Si3N4) integrated photonics for sensing applications, ranging from refractive index to spectroscopic sensing. By making use of advanced CMOS technology,complex miniaturized circuits can be easily realized on a large scale and at a low cost covering visible to mid-IR wavelengths. In this paper we present our recent work on the development of silicon and Si3N4-based photonic integrated circuits for various spectroscopic sensing applications. We report our findings on waveguide-based absorption, and Raman and surface enhanced Raman spectroscopy. Finally we report on-chip spectrometers and on-chip broadband light sources covering very near-IR to mid-IR wavelengths to realize fully integrated spectroscopic systems on a chip.Ananth Z.Subramanian Eva Ryckeboer Ashim Dhakal Frédéric Peyskens Aditya Malik Bart Kuyken Haolan Zhao Shibnath Pathak Alfonso Ruocco Andreas De Groote Pieter Wuytens Daan Martens Francois Leo Weiqiang Xie Utsav Deepak Dave Muhammad Muneeb Pol Van Dorpe Joris Van Campenhout Wim Bogaerts Peter Bienstman Nicolas Le Thomas Dries Van Thourhout Zeger Hens Gunther Roelkens Roel Baets 2015Photonics Research2015,3,5:7
4Effects of glutamine supplementation on gut barrier,glutathione content and acute phase response in malnourished rats during inflammatory shock显示文摘AIM: To evaluate the effect of glutamine on intestinal mucosa integrity,glutathione stores and acute phase response in protein-depleted rats during an inflammatory shock. METHODS: Plasma acute phase proteins (APP),jejunal APP mRNA levels,liver and jejunal glutathione concentrations were measured before and one,three and seven days after turpentine injection in 4 groups of control,protein-restricted,protein-restricted rats supplemented with glutamine or protein powder. Bacterial translocation in mesenteric lymph nodes and intestinal morphology were also assessed. RESULTS: Protein deprivation and turpentine injection significantly reduced jejunal villus height,and crypt depths. Mucosal glutathione concentration significantly decreased in protein-restricted rats. Before turpentine oil,glutamine supplementation restored villus heights and glutathione concentration (3.24 ± 1.05 vs 1.72 ± 0.46 μmol/g tissue,P < 0.05) in the jejunum,whereas in the liver glutathione remained low. Glutamine markedly increased jejunal α1-acid glycoprotein mRNA level after turpentine oil but did not affect its plasma concentration. Bacterial translocation in protein-restricted rats was not prevented by glutamine or protein powder supplementation. CONCLUSION: Glutamine restored gut glutathione stores and villus heights in malnourished rats but had no preventive effect on bacterial translocation in our model.Liliana Belmonte Mose Co■ffier Florence Le Pessot Olga Miralles-Barrachina Martine Hiron Antony Leplingard Jean-Franois Lemeland Bernadette Hecketsweiler Maryvonne Daveau Philippe Ducrotté Pierre Déchelotte 2007World Journal of Gastroenterology2007,13,20:6
5Evaluation of Doppler-ultrasonography in the diagnosis of transjugular intrahepatic portosystemic shunt dysfunction: A prospective study显示文摘AIM To prospectively evaluate the performance of Dopplerultrasonography(US) for the detection of transjugular intrahepatic portosystemic shunt(TIPS) dysfunction within a multicenter cohort of cirrhotic patients.METHODS This study was conducted in 10 french teaching hospitals. After TIPS insertion, angiography and liver Doppler-US were carried out every six months to detect dysfunction(defined by a portosystemic gradient ≥ 12 mm Hg and/or a stent stenosis ≥ 50%). The association between ultrasonographic signs and dysfunction was studied by logistic random-effects models, and the diagnostic performance of each Doppler criterion was estimated by the bootstrap method. This study was approved by the ethics committee of Tours.RESULTS Two hundred and eighteen pairs of examinations performed on 87 cirrhotic patients were analyzed. Variables significantly associated with dysfunction were: The speed of flow in the portal vein(P = 0.008), the reversal of flow in the right(P = 0.038) and left(P = 0.049) portal branch, the loss of modulation of portal flow by the right atrium(P = 0.0005), ascites(P = 0.001) and the overall impression of the operator(P = 0.0001). The diagnostic performances of these variables were low; sensitivity was < 58% and negative predictive value was < 73%. Therefore, dysfunction cannot be ruled out from Doppler-US. CONCLUSION The performance of Doppler-US for the detection of TIPS dysfunction is poor compared to angiography. New tools are needed to improve diagnosis of TIPS dysfunction.Charlotte Nicolas Amelie Le Gouge Louis d’Alteroche Jean Ayoub Monica Georgescu Vincent Vidal Denis Castaing Jean-Pierre Cercueil Patrick Chevallier Jerome Roumy Herve Trillaud Louis Boyer Vincent Le Pennec Christophe Perret Bruno Giraudeau Jean-Marc Perarnau STIC-TIPS group 2017World Journal of Hepatology2017,9,27:6

9Relationship between skin fold thickness and insulin resistance in the essential hypertensive patients in Vietnam显示文摘Previous studies reported a close relationship between obesity and insulin resistance in the essential hypertensive patients. Objective In this study, we examined the relationship between the skin fold thickness and insulin resistance then developed a formula to estimate the insulin resistance index according to the skin fold thickness in the essential hypertensive patients. Subjects and Methods Medical records of 80 patients (37 males, 43 females) were reviewed and the data were tabulated. Anthropometric indexes (including height, weight, waist circumference, hip circumference, and skins fold thickness at 5 fatty difference points on the Erdheim diagram), fasting plasma glucose and insulin concentration were recorded. The mean age was 57.0±9.2 years. The insulin resistance index was calculated following the Homeostasis Model Assessment (HOMA) formula. Results Compared with the group with BMI<23kg/m2, the group with BMI≥23 kg/m2 had higher fasting insulin concentration (8.85 ± 4.97 pmol/L vs 15.60 ± 8.70 pmol/L, P<0.001 ) and higher insulin resistance index in (2.15±1,24 vs 3.76±2.22, P<0.001). No significant difference in fasting plasma insulin concentration,insulin resistance index between male and female was observed (P>0.05). There was a positive correlation between skin fold thickness and the fasting insulin concentration and insulin resistance index. The skin fold thickness at point A8 had the best coefficient correlated with fasting plasma insulin(r=0.79, P<0.001) and insulin resistance index (r= 0.79, P < 0.001). A formula to estimate the insulin resistance index by skin fold thickness at point A8 as: Insulin resistance index = 0.12 × [skin fold thickness at A8 point (mm)] - 1.Conclusion: In the essential hypertensive patients, the formula to estimate insulin resistance index as 0.12 × [skin fold thickness at A8 point (mm)]-1 may predict accurately the level of insulin resistance.Toan C Nguyen Khoa TA Pham Quyen TL Do Cuong T Nguyen Diep D Nguyen Vinh G Le Cong D Nguyen 2005Journal of Geriatric Cardiology2005,2,4:4
10Transient micro-elastography:A novel non-invasive approach to measure liver stiffness in mice显示文摘AIM:To develop and validate a transient micro-elastography device to measure liver stiffness(LS) in mice.METHODS:A novel transient micro-elastography(TME) device,dedicated to LS measurements in mice with a range of measurement from 1-170 kPa,was developed using an optimized vibration frequency of 300 Hz and a 2 mm piston.The novel probe was validated in a classical fibrosis model(CCl4) and in a transgenic murine model of systemic amyloidosis.RESULTS:TME could be successfully performed in control mice below the xiphoid cartilage,with a mean LS of 4.4 ± 1.3 kPa,a mean success rate of 88%,and an excellent intra-observer agreement(0.98).Treatment with CCl4 over seven weeks drastically increased LS as compared to controls(18.2 ± 3.7 kPa vs 3.6 ± 1.2 kPa).Moreover,fibrosis stage was highly correlated with LS(Spearman coefficient = 0.88,P < 0.01).In the amyloidosis model,much higher LS values were obtained,reaching maximum values of > 150 kPa.LS significantly correlated with the amyloidosis index(0.93,P < 0.0001) and the plasma concentration of mutant hapoA-□(0.62,P < 0.005).CONCLUSION:Here,we have established the first non-invasive approach to measure LS in mice,and have successfully validated it in two murine models of high LS.Cécile Bastard Matteo R Bosisio Michèle Chabert Athina D Kalopissis Meriem Mahrouf-Yorgov Hélène Gilgenkrantz Sebastian Mueller Laurent Sandrin 2011World Journal of Gastroenterology2011,17,8:4

19胚胎巨噬细胞和小胶质细胞消融调控小鼠胚胎背根神经节感觉神经元的发育显示文摘众所周知,小胶质细胞可以调节中枢神经系统发育的一些方面。在第11.5天的小鼠胚胎中的小胶质细胞定殖脊髓时,它们与背根神经节感觉神经元(SN)的生长中心轴突相互作用,这表明它们可能在SN发育中发挥一定功能。为了解决这个问题,我们使用缺乏胚胎巨噬细胞(PU.1敲除小鼠)和免疫细胞消融的小鼠胚胎分析胚胎巨噬细胞消融对SNs早期发育的影响。我们发现,除小胶质细胞外,胚胎巨噬细胞还与来自第11.5天的小鼠胚胎的原肌球蛋白受体激酶(Trk)C+感觉神经元,TrkB+感觉神经元和TrkA+感觉神经元外周神经突产生交联。免疫细胞剥夺会导致第11.5天的小鼠胚胎的TrkC+感觉神经元和TrkB+感觉神经元初始数量的减少,这与其发育细胞死亡(DCD)的改变有关联的可能性较小,因为其后在第12.5天的胚胎中的数量有短暂增加。在分析的发育期(第11.5~15.5天),它也导致TrkA+感觉神经元数量减少,尽管我们没有观察到他们的DCD有任何变化。与神经元祖细胞可能存在一致性的脑脂肪酸结合蛋白(BFABP-)阴性细胞的增殖在第11.5天的胚胎中增加,而它们的增殖在第12.5天的胚胎减少,这可部分解释从11.5 d观察到的SN亚型产生的改变。此外,我们观察到在缺乏胚胎巨噬细胞的情况下神经胶质细胞祖细胞(BFABP+细胞)增殖的改变。我们的数据表明,胚胎巨噬细胞和小胶质细胞消融调控SN的发育。Angelim MKSC Maia LMSS Mouffle C Ginhoux F Low D Amancio-Dos-Santos A Makhoul J Le Corronc H Mangin JM Legendre P 聂昊(编译) 2018神经损伤与功能重建2018,13,9:2
2025 Gbps low-voltage hetero-structured silicongermanium waveguide pin photodetectors for monolithic on-chip nanophotonic architectures显示文摘Near-infrared germanium(Ge) photodetectors monolithically integrated on top of silicon-on-insulator substrates are universally regarded as key enablers towards chip-scale nanophotonics, with applications ranging from sensing and health monitoring to object recognition and optical communications. In this work, we report on the highdata-rate performance pin waveguide photodetectors made of a lateral hetero-structured silicon-Ge-silicon(Si-Ge-Si) junction operating under low reverse bias at 1.55 μm. The pin photodetector integration scheme considerably eases device manufacturing and is fully compatible with complementary metal-oxide-semiconductor technology. In particular, the hetero-structured Si-Ge-Si photodetectors show efficiency-bandwidth products of^9 GHz at-1 V and ~30 GHz at-3 V, with a leakage dark current as low as ~150 nA, allowing superior signal detection of high-speed data traffic. A bit-error rate of 10-9 is achieved for conventional 10 Gbps, 20 Gbps, and25 Gbps data rates, yielding optical power sensitivities of-13.85 dBm,-12.70 dBm, and-11.25 dBm, respectively. This demonstration opens up new horizons towards cost-effective Ge pin waveguide photodetectors that combine fast device operation at low voltages with standard semiconductor fabrication processes, as desired for reliable on-chip architectures in next-generation nanophotonics integrated circuits.DANIEL BENEDIKOVIC LéOPOLD VIROT GUY AUBIN FARAH AMAR BERTRAND SZELAG BAYRAM KARAKUS JEAN-MICHEL HARTMANN CARLOS ALONSO-RAMOS XAVIER LE ROUX PAUL CROZAT ERIC CASSAN DELPHINE MARRIS-MORINI CHARLES BAUDOT FRéDéRIC BOEUF JEAN-MARC FéDéLI CHRISTOPHE KOPP LAURENT VIVIEN 2019Photonics Research2019,7,4:2
