1Stage and size using magnetic resonance imaging and endosonography in neoadjuvantly-treated rectal cancer显示文摘AIM: To assess the stage and size of rectal tumours using 1.5 Tesla (1.5T) magnetic resonance imaging (MRI) and three-dimensional (3D) endosonography (ERUS). METHODS: In this study, patients were recruited in a phaseⅠ/Ⅱ trial of neoadjuvant chemotherapy for biopsy-proven rectal cancer planned for surgical resection with or without preoperative radiotherapy. The feasibility and accuracy of 1.5T MRI and 3D ERUS were compared with the histopathology of the fixed surgical specimen (pathology) to determine the stage and size of the rectal cancer before and after neoadjuvant chemotherapy. A Philips Intera 1.5T with a cardiac 5-channel synergy surface coil was used for the MRI, and a B-K Medical Falcon 2101 EXL 3D-Probe was used at 13 MHz for the ERUS. Our hypothesis was that the staging accuracy would be the same when using MRI, ERUS and a combination of MRI and ERUS. For the combination, MRI was chosen for the assessment of the lymph nodes, and ERUS was chosen for the assessment of perirectal tissue penetration. The stage was dichotomised into stageⅠ and stage Ⅱ or greater. The size was measured as the supero-inferior length and the maximal transaxial area of the tumour. RESULTS: The staging feasibility was 37 of 37 for the MRI and 29 of 36 for the ERUS, with stenosis as a limiting factor. Complete sets of investigations were available in 18 patients for size and 23 patients for stage. The stage accuracy by MRI, ERUS and the combination of MRI and ERUS was 0.65, 0.70 and 0.74, respectively, before chemotherapy and 0.65, 0.78 and 0.83, respectively, after chemotherapy. The improvement of the post-chemotherapy staging using the combination of MRI and ERUS compared with the staging using MRI alone was significant (P = 0.046). The post-chemotherapy understaging frequency by MRI, ERUS and the combination of MRI and ERUS was 0.18, 0.14 and 0.045, respectively, and these differences were non-significant. The measurements of the supero-inferior length by ERUS compared with MRI were within 1.96 standard deviations of the difference between the methods (18 mm) for tumours smaller than 50 mm. The agreement with pathology was within 1.96 standard deviations of the difference between imaging and pathology for all tumours with MRI (15 mm) and for tumours that did not exceed 50 mm with ERUS (22 mm). Tumours exceeding 50 mm in length could not be reliably measured by ERUS due to the limit in the length of each recording. CONCLUSION: MRI is preferable to use when assessing the size of large or stenotic rectal tumours. However, staging accuracy is improved by combining MRI with ERUS.Torbjrn Swartling Peter Klebo Kristoffer Derwinger Bengt Gustavsson Gran Kurlberg 2013World Journal of Gastroenterology2013,19,21:9
2High-throughput screening and machine learning for the efficient growth of high-quality single-wall carbon nanotubes显示文摘It has been a great challenge to optimize the growth conditions toward structure-controlled growth of single-wall carbon nanotubes(SWCNTs).Here,a high-throughput method combined with machine learning is reported that efficiently screens the growth conditions for the synthesis of high-quality SWCNTs.Patterned cobalt(Co)nanoparticles were deposited on a numerically marked silicon wafer as catalysts,and parameters of temperature,reduction time and carbon precursor were optimized.The crystallinity of the SWCNTs was characterized by Raman spectroscopy where the featured G/D peak intensity(IG/ID)was extracted automatically and mapped to the growth parameters to build a database.1,280 data were collected to train machine learning models.Random forest regression(RFR)showed high precision in predicting the growth conditions for high-quality SWCNTs,as validated by further chemical vapor deposition(CVD)growth.This method shows great potential in structure-controlled growth of SWCNTs.Zhong-Hai Ji Lili Zhang Dai-Ming Tang Chien-Ming Chen Torbjörn EMNordling Zheng-De Zhang Cui-Lan Ren Bo Da Xin Li Shu-Yu Guo Chang Liu Hui-Ming Cheng 2021Nano Research2021,14,12:3
3Chicory(Cichorium intybus L.) and cereals differently affect gut development in broiler chickens and young pigs显示文摘Dietary fiber,resistant to host-mediated digestion in the small intestine due to lack of endogenous enzymes,impacts many facets of animal health and is associated with gut development especially in young monogastrics.Furthermore,it can be used as in-feed antibiotic alternative.Chicory(Cichorium intybus L.) forage with high content of pectin(uronic acids as building blocks) is a novel class of dietary fiber that is chemically different from cereal grains(with high content of arabinoxylans).In the present study,we investigated effects of dietary inclusion of chicory forage on digestibility,gut morphology and microbiota in broilers and young pigs.In the chicken experiment,160 1-d old broiler chicks were fed 3 nutritionally balanced diets for 30 d including a cereal-based diet and 2 diets with part of the cereals substituted with 60 and 120 g/kg chicory forage(CF60 and CF120),whereas in the pig experiment,18 seven-wk old Yorkshire pigs were fed 3 diets for 18 d including a cereal-based diet and2 diets with 80 and 160 g/kg chicory forage inclusion(CF80 and CF160).Our results showed that young pigs were capable to utilize chicory forage well with higher total tract apparent digestibility(TTAD) of all fiber fractions,particularly uronic acid,compared with the control(P< 0.01).In contrast,a decreased TTAD of all fiber fractions was observed in chickens fed on diet CF120(P< 0.05).Moreover,diet induced changes in gut morphology were observed in the large intestine of chickens.The alteration of cecal mucosal thickness was further positively correlated with TTAD of non-starch polysaccharides(NSP) and its constituent sugars(P < 0.05).In addition,in pigs,terminal restriction fragment length polymorphism(T-RFLP) analysis of intestinal microbiota revealed substantial dietary effects(cereal control diet vs.chicory forage inclusion) on the relative abundance of 2 dominant bacterial phylotypes(Prevotella sp.vs.Roseburia sp.) respectively(P< 0.05).In conclusion,our data showed that chicory forage(Cichorium intybus L),a novel dietary fiber source in animal nutrition,have potential beneficial properties as fiber ingredient in diets for both pigs and chickens.Haoyu Liu Emma Ivarsson Torbjrn Lundh Jan Erik Lindberg 2014Journal of Animal Science and Biotechnology2014,5,2:2
