1文化融入与中国留学生的适应显示文摘本研究的目的是探讨两个维度 (主族和客族文化认同 )、四种方式 (整合、分离、同化和边缘 )及其与中国留学生适应的关系。采用一套问卷测验 (包括文化融入指数、社会文化适应问题及主观幸福感等测验量表 )调查了在澳大利亚的 1 57名中国留学生。结果表明在调查的中国留学生中 ,整合者占40 1 % ,分离者占 42 7% ,同化者占 8 3% ,而边缘者占 8 9% ,中国留学生的主族和客族文化认同指标均与心理适应指标有显著的正相关 ;在心理适应方面 ,整合者最好 ,其次为同化者和分离者 ,最差为边缘者。对于留学生出国前的选拔和培训 ,出国后的教育与学习 ,有关部门和学校应重视其文化认同和文化融入方式等因素 ,以便更好地帮助留学生适应新的环境 ,提高留学生教育质量。郑雪 David Sang 2003应用心理学2003,9,1:62
2Endoscopy and polyps-diagnostic and therapeutic advances in management显示文摘Despite multiple efforts aimed at early detection through screening, colon cancer remains the third leading cause of cancer-related deaths in the United States, with an estimated 51000 deaths during 2013 alone. The goal remains to identify and remove benign neoplastic polyps prior to becoming invasive cancers. Polypoid lesions of the colon vary widely from hyperplastic, hamartomatous and inflammatory to neoplastic adenomatous growths. Although these lesions are all benign, they are common, with up to one-quarter of patients over 60 years old will develop pre-malignant adenomatous polyps. Colonoscopy is the most effective screening tool to detect polyps and colon cancer, although several studies have demonstrated missed polyp rates from 6%-29%, largely due to variations in polyp size. This number can be as high as 40%, even with advanced (> 1 cm) adenomas. Other factors including sub-optimal bowel preparation, experience of the endoscopist, and patient anatomical variations all affect the detection rate. Additional challenges in decision-making exist when dealing with more advanced, and typically larger, polyps that have traditionally required formal resection. In this brief review, we will explore the recent advances in polyp detection and therapeutic options.Scott R Steele Eric K Johnson Bradley Champagne Brad Davis Sang Lee David Rivadeneira Howard Ross Dana A Hayden Justin A Maykel 2013World Journal of Gastroenterology2013,19,27:16
3Black phosphorus-based field effect transistor devices for Ag ions detection显示文摘Black phosphorus(BP), an attractive two-dimensional(2 D) semiconductor, is widely used in the fields of optoelectronic devices, biomedicine, and chemical sensing. Silver ion(Ag^+), a commonly used additive in food industry, can sterilize and keep food fresh. But excessive intake of Ag^+will harm human health. Therefore, high sensitive, fast and simple Ag+detection method is significant. Here, a high-performance BP field effect transistor(FET) sensor is fabricated for Ag^+detection with high sensitivity, rapid detection speed, and wide detection concentration range. The detection limit for Ag^+is 10^(-10) mol/L. Testing time for each sample by this method is 60 s. Besides, the mechanism of BP-FET sensor for Ag^+detection is investigated systematically. The simple BP-FET sensor may inspire some relevant research and potential applications, such as providing an effective method for the actual detection of Ag^+, especially in witnessed inspections field of food.王慧德 David K Sang 郭志男 曹睿 赵劲来 Muhammad Najeeb Ullah Shah 范涛健 范滇元 张晗 2018Chinese Physics B2018,27,8:4

7Modeling the impacts of temperature and precipitation changes on soil CO_2 fluxes from a Switchgrass stand recently converted from cropland显示文摘Switchgrass(Panicum virgatum L.) is a perennial C_4 grass native to North America and successfully adapted to diverse environmental conditions. It offers the potential to reduce soil surface carbon dioxide(CO_2) fluxes and mitigate climate change. However, information on how these CO_2 fluxes respond to changing climate is still lacking. In this study, CO_2 fluxes were monitored continuously from 2011 through 2014 using high frequency measurements from Switchgrass land seeded in 2008 on an experimental site that has been previously used for soybean(Glycine max L.) in South Dakota, USA. DAYCENT, a process-based model, was used to simulate CO_2 fluxes. An improved methodology CPTE[Combining Parameter estimation(PEST) with 'Trial and Error' method] was used to calibrate DAYCENT. The calibrated DAYCENT model was used for simulating future CO_2 emissions based on different climate change scenarios. This study showed that:(i) the measured soil CO_2 fluxes from Switchgrass land were higher for 2012 which was a drought year, and these fluxes when simulated using DAYCENT for long-term(2015–2070) provided a pattern of polynomial curve;(ii) the simulated CO_2 fluxes provided different patterns with temperature and precipitation changes in a long-term,(iii) the future CO_2 fluxes from Switchgrass land under different changing climate scenarios were not significantly different, therefore, it can be concluded that Switchgrass grown for longer durations could reduce changes in CO_2 fluxes from soil as a result of temperature and precipitation changes to some extent.Liming Lai Sandeep Kumar Rajesh Chintala Vance N.

20Redox sensor QSOX1 regulates plant immunity by targeting GSNOR to modulate ROS generation显示文摘Reactive oxygen signaling regulates numerous biological processes,including stress responses in plants.Redox sensors transduce reactive oxygen signals into cellular responses.Here,we present biochemical evidence that a plant quiescin sulfhydryl oxidase homolog(QSOX1)is a redox sensor that negatively regulates plant immunity against a bacterial pathogen.The expression level of QSOX1 is inversely correlated with pathogen-induced reactive oxygen species(ROS)accumulation.Interestingly,QSOX1 both senses and regulates ROS levels by interactingn with and mediating redox regulation of S-nitrosoglutathione reductase,which,consistent with previous findings,influences reactive nitrogen-mediated regulation of ROS generation.Collectively,our data indicate that QSOX1 is a redox sensorthat negatively regulates plant immunity by linking reactive oxygen and reactive nitrogen signaling to limit ROS production.Ho Byoung Chae Min Gab Kim Chang Ho Kang Joung Hun Park Eun Seon Lee Sang-Uk Lee Yong Hun Chi Seol Ki Paeng Su Bin Bae Seong Dong Wi Byung-Wook Yun Woe-Yeon Kim Dae-Jin Yun David Mackey Sang Yeol Lee 2021Molecular Plant2021,14,8:1
