1Effects 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

4Tribological behaviors of Ni-modified citric acid carbon quantum dot particles as a green additive in polyethylene glycol显示文摘A novel green lubricating oil additive(carbon quantum dot(CQD)particle‐doped nickel(Ni‐CQD))was synthesized from citric acid and nickel acetate.The effects of CQD and Ni‐CQD nanoparticles on the tribological behaviors of polyethylene glycol(PEG200)were investigated under different loads and reciprocation speeds.The results indicate that CQD and Ni‐CQD particles can both enhance the lubrication properties of PEG200.However,the Ni‐CQD nanoparticles enhanced the lubrication properties more than the plain CQD particles did.The average friction coefficient and wear rate of PEG200 containing 2 wt%Ni‐CQDs were reduced by 35.5%and 36.4%,respectively,compared to PEG200 containing pure CQDs under a load of 8 N and reciprocation speed of 25 mm/s over 60 min.The friction and wear mechanisms are attributed to the fact that friction induces the Ni‐CQDs to participate in the formation of a tribofilm,resulting in a low friction coefficient and wear rate.Zhiqiang TU Enzhu HU Bangbang WANG Karl D DAVID Philipp SEEGER Martin MONEKE Ralph STENGLER Kunhong HU Xianguo HU 2020Friction2020,8,1:5

6Management of digestive bleeding related to portal hypertension in cirrhotic patients:A French multicenter cross-sectional practice survey显示文摘AIM: To investigate the conformity of management practices of gastrointestinal hemorrhage in cirrhotic patients with relevant guidelines. METHODS: A questionnaire on the management of digestive bleeding was completed for all consecutive cirrhotic patients admitted to 31 French hospitals. RESULTS: One hundred and twenty-six bleeding events were recorded. It was the first bleeding episode in 79 patients (63%), of whom 40 (51%) had a prior diagnosis of cirrhosis and 25 (32%) had previously undergone an endoscopy. The bleeding episode was a recurrence in 46 patients (37%). The median time between onset and admission was 4 h, but exceeded 12 h in 42% of cases. There was an agreement between centers forearly vasoactive drug administration (87% of cases), association with ligation (42%) more often than sclerosis (21%) at initial endoscopy, and antibiotic prophylaxis (64%). By contrast, prescription of beta-blockade alone or in combination (0 to 100%, P = 0.003) for secondary prophylaxis and lactulose (26% to 86%, P = 0.04), differed among centers. CONCLUSION: In French hospitals, management of bleeding related to portal hypertension in cirrhotic patients is generally in keeping with the consensus. Broad variability still remains concerning beta-blockade use for secondary prophylaxis. Screening for esophageal varices, the use of antibiotic prophylaxis and patients information need to be improved.Pierre Ingrand Jérme Gournay Pierre Bernard Frédéric Oberti Brigitte Bernard-Chabert Arnault Pauwels Philippe Renard Eric Bartoli Jean-Franois Cadranel Jean-Claude Barbare Isabelle Ingrand Michel Beauchant 2006World Journal of Gastroenterology2006,12,48:4

11Dual-color deep-tissue three-photon microscopy with a multiband infrared laser显示文摘Multiphoton microscopy combined with genetically encoded fluorescent indicators is a central tool in biology.Threephoton(3P)microscopy with excitation in the short-wavelength infrared(SWIR)water transparency bands at 1.3 and 1.7μm opens up new opportunities for deep-tissue imaging.However,novel strategies are needed to enable in-depth multicolor fluorescence imaging and fully develop such an imaging approach.Here,we report on a novel multiband SWIR source that simultaneously emits ultrashort pulses at 1.3 and 1.7μm that has characteristics optimized for 3P microscopy:sub-70 fs duration,1.25 MHz repetition rate,and μJ-range pulse energy.In turn,we achieve simultaneous 3P excitation of green fluorescent protein(GFP)and red fluorescent proteins(mRFP,mCherry,tdTomato)along with third-harmonic generation.We demonstrate in-depth dual-color 3P imaging in a fixed mouse brain,chick embryo spinal cord,and live adult zebrafish brain,with an improved signal-to-background ratio compared to multicolor twophoton imaging.This development opens the way towards multiparametric imaging deep within scattering tissues.Khmaies Guesmi Lamiae Abdeladim Samuel Tozer Pierre Mahou Takuma Kumamoto Karolis Jurkus Philippe Rigaud Karine Loulier Nicolas Dray Patrick Georges Marc Hanna Jean Livet Willy Supatto Emmanuel Beaurepaire Frédéric Druon 2018Light(Science & Applications)2018,7,1:3

14Stable femtosecond X-rays with tunable polarization from a laser-driven accelerator显示文摘Technology based on high-peak-power lasers has the potential to provide compact and intense radiation sources for a wide range of innovative applications.In particular,electrons that are accelerated in the wakefield of an intense laser pulse oscillate around the propagation axis and emit X-rays.This betatron source,which essentially reproduces the principle of a synchrotron at the millimeter scale,provides bright radiation with femtosecond duration and high spatial coherence.However,despite its unique features,the usability of the betatron source has been constrained by its poor control and stability.In this article,we demonstrate the reliable production of X-ray beams with tunable polarization.Using ionization-induced injection in a gas mixture,the orbits of the relativistic electrons emitting the radiation are reproducible and controlled.We observe that both the signal and beam profile fluctuations are significantly reduced and that the beam pointing varies by less than a tenth of the beam divergence.The polarization ratio reaches 80%,and the polarization axis can easily be rotated.We anticipate a broad impact of the source,as its unprecedented performance opens the way for new applications.Andreas Döpp Benoit Mahieu Agustin Lifschitz Cedric Thaury Antoine Doche Emilien Guillaume Gabriele Grittani Olle Lundh Martin Hansson Julien Gautier Michaela Kozlova Jean Philippe Goddet Pascal Rousseau Amar Tafzi Victor Malka Antoine Rousse Sebastien Corde Kim Ta Phuoc 2017Light(Science & Applications)2017,6,1:2

20Role of endoscopic ultrasound in the screening and follow-up of high-risk individuals for familial pancreatic cancer显示文摘Managing familial pancreatic cancer(FPC)is challenging for gastroenterologists,surgeons and oncologists.High-risk individuals(HRI)for pancreatic cancer(PC)(FPC or with germline mutations)are a heterogeneous group of subjects with a theoretical lifetime cumulative risk of PC over 5%.Screening is mainly based on annual magnetic resonance imaging(MRI)and endoscopic ultrasound(EUS).The goal of screening is to identify early-stage operable cancers or high-risk precancerous lesions(pancreatic intraepithelial neoplasia or intraductal papillary mucinous neoplasms with high-grade dysplasia).In the literature,target lesions are identified in 2%-5%of HRI who undergo screening.EUS appears to provide better identification of small solid lesions(0%-46%of HRI)and chronicpancreatitis-like parenchymal changes(14%-77%of HRI),while MRI is probably the best modality to identify small cystic lesions(13%-49%of HRI).There are no specific studies in HRI on the use of contrast-enhanced harmonic EUS.EUS can also be used to obtain tissue samples.Nevertheless,there is still limited evidence on the accuracy of imaging procedures used for screening or agreement on which patients to treat.The cost-effectiveness of screening is also unclear.Certain new EUS-related techniques,such as searching for DNA abnormalities or protein markers in pancreatic fluid,appear to be promising.Diane Lorenzo Vinciane Rebours Frédérique Maire Maxime Palazzo Jean-Michel Gonzalez Marie-Pierre Vullierme Alain Aubert Pascal Hammel Philippe Lévy Louis de Mestier 2019World Journal of Gastroenterology2019,25,34:2
