1Confocal laser endomicroscopy and immunoendoscopy for real-time assessment of vascularization in gastrointestinal malignancies显示文摘Gastrointestinal cancers represent a major cause of morbidity and mortality,with incomplete response to chemotherapy in the advanced stages and poor prognosis.Angiogenesis plays a crucial part in tumor growth and metastasis,with most gastrointestinal cancers depending strictly on the development of a new and devoted capillary network.Confocal laser endomicroscopy is a new technology which allows in vivo microscopic analysis of the gastrointestinal mucosa and its microvascularization during ongoing endoscopy by using topically or systemically administered contrast agents.Targeting markers of angiogenesis in association with confocal laser endomicroscopic examination(immunoendoscopy),as a future challenge,will add functional analysis to the morphological aspect of the neoplastic process.This review describes previous experience in endomicroscopic examination of the upper and lower digestive tract with emphasis on vascularization,resulting in a broad spectrum of potential clinical applications,and also preclinical research that could be translated to human studies.Dan Ionut Gheonea Tatiana Crtnǎ Tudorel Ciurea Carmen Popescu Anca Bǎdǎrǎu Adrian Sǎftoiu 2011World Journal of Gastroenterology2011,17,1:6

3Comparative carbon emission assessments of recycled and natural aggregate concrete: Environmental influence of cement content显示文摘This work examines the environmental and geochemical impact of recycled aggregate concrete production with properties representative for structural applications.The environmental influence of cement content,aggregate production,transportation,and waste landfilling is analysed by undertaking a life cycle assessment and considering a life cycle inventory largely specific for the region.To obtain a detailed insight into the optimum life cycle parameters,a sensitivity study is carried out in which supplementary cementitious materials,different values of natural-to-recycled aggregate content ratio and case-specific transportation distances were considered.The results show that carbon emissions were between 323 and 332 kgCO_(2)e per cubic metre of cement only natural aggregate concrete.These values can be reduced by up to 17%by replacing 25%of the cement with fly ash.By contrast,carbon emissions can increase when natural coarse aggregates are replaced by recycled aggregates in proportions of 50%and 100%,and transportation is not included in analysis.However,the concrete with 50%recycled aggregate presented lower increase,only 0.3%and 3.4%for normal and high strength concrete,respectively.In some cases,the relative contribution of transportation to the total carbon emissions increased when cement was replaced by fly ash in proportions of 25%,and case-specific transportation distances were considered.In absolute values,the concrete mixes with 100%recycled aggregates and 25%fly ash had lower carbon emissions than concrete with cement and natural aggregates only.Higher environmental benefits can be obtained when the transportation distances of fly ash are relatively short(15–25 km)and the cement replacement by fly ash is equal or higher than 25%,considering that the mechanical properties are adequate for practical application.The observations from this paper show that recycled aggregate concrete with strength characteristics representative for structural members can have lower carbon emissions than conventional concrete,recommending them as an alternative to achieving global sustainability standards in construction.Marian Sabǎu Dan V.Bompa Luis F.O.Silva 2021Geoscience Frontiers2021,12,6:2

19Integrated scanning spectrometer with a tunable micro-ring resonator and an arrayed waveguide grating显示文摘Integrated spectrometers with both wide optical bandwidths and high spectral resolutions are required in applications such as spectral domain optical coherence tomography(SD-OCT).Here we propose a compact integrated scanning spectrometer by using a tunable micro-ring resonator(MRR)integrated with a single arrayed waveguide grating for operation in the 1265-1335-nm range.The spectral resolution of the spectrometer is determined by the quality factor of the MRR,and the optical bandwidth is defined by the free spectral range of the arrayed waveguide grating.The spectrometer is integrated with on-chip germanium photodetectors,which enable direct electrical readout.A 70-nm optical bandwidth and a 0.2-nm channel spacing enabled by scanning the MRR across one free spectral range are demonstrated,which offer a total of350 wavelength channels with 31-kHz wavelength scanning speed.The integrated spectrometer is applied to measure different spectra and the interference signals from an SD-OCT system,which shows its great potential for future applications in sensing and imaging systems.ZUNYUE ZHANG YI WANG JIARUI WANG DAN YI DAVID WENG U CHAN WU YUAN HON KI TSANG 2022Photonics Research2022,10,5:1
