1高光谱遥感在农作物长势监测中的应用显示文摘该研究是加拿大Saskatchewan Scott农作物轮作系统(ACS)研究的一部分。研究始于1994年,历时18a,评价9个可耕种农作物产量系统的可靠性。由3种处理水平(organic,reduced,high)和3种作物多样性水平(low,diversified annual grains,diversified annual perennials)结合而产生的9个农作物产量系统,被用于监测和评价加拿大牧场不同处理和不同作物种植轮作下可耕种农作物的产量。在2003年生长季共收集了3次叶面积指数和光谱反射率的数据:生长季前期(6月)、生长季旺盛期(7月)、生长季后期(8月)。叶面积指数是由LAI-2000植物冠层分析仪监测的,光谱测量是由覆盖了350-2500 nm波长范围共2215个波段的ADS便携式高光谱仪完成的。结果显示,光学测量可以用于监测农作物生长状况的差异。从生长季的早期到中期,光谱和叶面积指数在不同处理下有显著差异。7月中期是用遥感资料监测农作物长势的最佳季节;红光波段与近红外波段反射率的比值和基于这两个波段构造的归一化植被指数,是检测农作物长势的最佳植被指数。郑有飞 Guo X Olfert O Brandt S Thomas G Weiss R Sproule L 2007气象与环境科学2007,30,1:22
2Gastric emptying, postprandial blood pressure, glycaemia and splanchnic flow in Parkinson's disease显示文摘AIM: To determine gastric emptying, blood pressure, mesenteric artery blood flow, and blood glucose responses to oral glucose in Parkinson's disease. METHODS: Twenty-one subjects(13 M, 8 F; age 64.2 ± 1.6 years) with mild to moderate Parkinson's disease(Hoehn and Yahr score 1.4 ± 0.1, duration of known disease 6.3 ± 0.9 years) consumed a 75 g glucose drink, labelled with 20 MBq 99mTc-calcium phytate. Gastric emptying was quantified with scintigraphy, blood pressure and heart rate with an automated device, superior mesenteric artery blood flow by Doppler ultrasonography and blood glucose byglucometer for 180 min. Autonomic nerve function was evaluated with cardiovascular reflex tests and upper gastrointestinal symptoms by questionnaire. RESULTS: The mean gastric half-emptying time was 106 ± 9.1 min, gastric emptying was abnormally delayed in 3 subjects(14%). Systolic and diastolic blood pressure fell(P < 0.001) and mesenteric blood flow and blood glucose(P < 0.001 for both) increased, following the drink. Three subjects(14%) had definite autonomic neuropathy and 8(38%) had postprandial hypotension. There were no significant relationships between changes in blood pressure, heart rate or mesenteric artery blood flow with gastric emptying. Gastric emptying was related to the score for autonomic nerve function(R = 0.55, P < 0.01). There was an inverse relationship between the blood glucose at t = 30 min(R =-0.52, P < 0.05), while the blood glucose at t = 180 min was related directly(R = 0.49, P < 0.05), with gastric emptying. CONCLUSION: In mild to moderate Parkinson's disease, gastric emptying is related to autonomic dysfunction and a determinant of the glycaemic response to oral glucose.Laurence G Trahair Thomas E Kimber Katerina Flabouris Michael Horowitz Karen L Jones 2016World Journal of Gastroenterology2016,22,20:5

5Targeted therapy in advanced metastatic colorectal cancer: Current concepts and perspectives显示文摘The introduction of new cytotoxic substances as well as agents that target vascular endothelial growth factor(VEGF)and epidermal growth factor receptor(EGFR)signaling has improved clinical outcome of patients withmetastatic colorectal cancer(mCRC).In this review we summarize the most relevant clinical data on VEGF and EGFR targeting regimens in mCRC.The effects of available treatment strategies for mCRC are often temporary,with resistance and disease progression developing in most patients.Thus,new treatment strategies are urgently needed.Some GI peptides including gastrin and gastrin releasing peptide,certain growth factors such as insulin-like growth factor-ⅠandⅡand neuropeptides such as growth hormone releasing hormone(GHRH)are implicated in the growth of CRC.Experimental investigations in CRC with antagonistic analogs of bombesin/gastrin-releasing peptide,GHRH,and with cytotoxic peptides that can be targeted to peptide receptors on tumors,are summarized in the second part of the review.Florian Hohla Thomas Winder Richard Greil Ferenc G Rick Norman L Block rew V Schally 2014World Journal of Gastroenterology2014,20,20:3

7Diagnostic accuracy of tests for Helicobacter pylori in an Alaska Native population显示文摘AIM:To evaluate the accuracy of two non-invasivetests in a population of Alaska Native persons. Highrates of Helico bacter pylori(H. pylori) infection,H. pylori treatment failure,and gastric cancer in this population necessitate documentation of infection status atmultiple time points over a patient's life.METHODS:In 280 patients undergoing endoscopy,H. pylori was diagnosed by culture,histology,rapidurease test,13C urea breath test(UBT) ,and immuno-globulin G antibodies to H. pylori in serum. The performances of 13C-UBT and antibody test were compared to a gold standard defined by a positive H. pylori testby culture or,in case of a negative culture result,bypositive histology and a positive rapid urease test.RESULTS:The sensitivity and specificity of the 13C-UBT were 93% and 88%,respectively,relative to thegold standard. The antibody test had an equivalents ensitivity of 93% with a reduced specificity of 68%.The false positive results for the antibody test were as-sociated with previous treatment for an H. pylori infection [relative risk(RR) = 2.8]. High levels of antibodiesto H. pylori were associated with chronic gastritis and male gender,while high scores in the 13C-UBT testwere associated with older age and with the H. pyloribacteria load on histological examination(RR = 4.4) .CONCLUSION:The 13C-UBT out performed the anti-body test for H. pylori and could be used when a non-invasive test is clinically necessary to document treatment out come or when monitoring for reinfection.Dana L Bruden Michael G Bruce Karen M Miernyk Julie Morris Debby Hurlburt Thomas W Hennessy Helen Peters Frank Sacco Alan J Parkinson Brian J McMahon 2011World Journal of Gastroenterology2011,17,42:3
