| 1 | The Impacts of Simulated Microgravity on Rat Brain Depended on Durations and Regions显示文摘Objective To explore the dynamic impacts of simulated microgravity(SM) on different vital brain regions of rats. Methods Microgravity was simulated for 7 and 21 days, respectively, using the tail-suspension rat model. Histomorphology, oxidative stress, inflammatory cytokines and the expression of some key proteins were determined in hippocampus, cerebral cortex and striatum. Results 21-day SM decreased brain derived neurotrophic factor and induced neuron atrophy in the cerebral cortex. Strong oxidative stress was triggered at day 7 and the oxidative status returned to physiological level at day 21. Inflammatory cytokines were gradually suppressed and in striatum, the suppression was regulated partially through c-Jun/c-Fos. Conclusion The results revealed that the significant impacts of SM on rat brain tissue depended on durations and regions, which might help to understand the health risk and to prevent brain damage for astronauts in space travel. | CHEN Bo ZHANG Yu Shi LI George CHO Jun-Lae DENG Yu Lin LI Yu Juan | 2019 | Biomedical and Environmental Sciences2019，32，7： | 4 |

| 4 | Evaluation of non-ampullary duodenal polyps: Comparison of non-neoplastic and neoplastic lesions显示文摘AIM: To evaluate duodenal polyps, divided into nonneoplastic and neoplastic lesions. In addition, the clinical characteristics of duodenal hyperplastic polyps are determined. METHODS: We analyzed medical records of 50 114 consecutive patients submitted to for first diagnostic esophago-gastroduodenoscopy between January 2004 and December 2009. We excluded lesions on the ampulla of Vater and submucosal tumors. We studied 510 cases that were diagnosed endoscopically with duodenal polyps and enrolled a total of 221 cases that had undergone tissue biopsy. We analyzed the differences between non-neoplastic and neoplastic lesions, and determined the clinical features of duodenal hyperplastic polyps. RESULTS: Non-neoplastic lesions were found in 196 patients and neoplastic lesions in 25 patients. On uni-variate analysis, there were significant differences in shape, location, and size. Polyps more than 10 mm in diameter or polyps in the second portion had independent risk factors for being neoplastic lesions, as identified by multivariate analysis. In 23 cases of hyperplastic polyps (79.3%), they were accompanied by gastroduodenal pathology, which was possibly associated with Helicobacter pylori . CONCLUSION: Polyps of more than 10 mm or polyps in the second portion of the duodenum should be evaluated by histological examination. | Sung Hoon Jung Woo Chul Chung Eun Jung Kim Seol Hye Kim Chang Nyol Paik Bo In Lee Young Seok Cho Kang-Moon Lee | 2010 | World Journal of Gastroenterology2010，16，43： | 2 |
| 5 | 微波辐射辅助柠檬酸络合法制备的Ho^(3+)/Tm^(3+)/Yb^(3+)共掺杂CaWO_4的白光性能(英文)显示文摘采用微波辐射辅助柠檬酸络合法制备Ho3+/Tm3+/Yb3+共掺杂CaWO4纳米晶升频转换荧光粉。将柠檬酸络合物前驱体在300~700°C热处理3 h。Ho3+/Tm3+/Yb3+共掺杂CaWO4C在400°C时开始结晶,在600°C时结晶完成。经600°C热处理的Ho3+/Tm3+/Yb3+共掺杂CaWO4主要呈球形,且形态均匀。在980 nm的激光激发下,Ho3+/Tm3+/Yb3+共掺杂CaWO4纳米晶出现肉眼可见的明亮的白色升频转换发射,这种现象来自Tm3+的475 nm蓝光发射以及Ho3+的543 nm绿光和651 nm红光发射。通过调整Tm3+和Ho3+的浓度可以控制Ho3+/Tm3+/Yb3+共掺杂CaWO4的CIE色度图从冷到暖白色之间变化。讨论了Tm3+和Ho3+浓度对升频转换光性能的影响以及与激光泵功率相关的影响机制。 | Hyun CHO Seok Min HWANG Jae Bin LEE Dong Hyun KA Tae Wan KIM Bo Seul LEE Ji Young LEE Jung-Il LEE Jeong Ho RYU | 2014 | Transactions of Nonferrous Metals Society of China2014，24，S1： | 2 |
