| 1 | 药用植物内生菌对作物生长及氧化应激的作用(英文)显示文摘目的:探讨药用植物内生菌的多样性及其在种子生长和氧化应激中的作用。方法:从三种药用植物(Caralluma acutangula、Rhazya stricta和Moringa peregrina)中提取内生菌;基于18S r DNA测序和系统发育分析鉴定分离得到的内生菌株;以正常和矮化突变体水稻品系为对照,比较不同浓度的内生菌培养滤液(CF)对水稻种子的发芽和生长的影响;通过气相色谱-质谱分析CF中的有效活性成分。结论:从药用植物中共获得10种内生菌,包括茎点霉属6株、链格孢属2株、双极霉属1株和枝孢霉属1株。CF表现出剂量依赖性的生长刺激和抑制作用。与对照和其他内生菌相比,100%的茎点霉菌CF显著促进了水稻种子的发芽和生长;双极霉中的吲哚乙酸含量最高,并表现出比其更高的自由基清除和抗脂质过氧化活性;双极霉菌和茎点霉菌的类黄酮和酚类成分较高。综上所述,药用植物中存在内生菌株,其可以用于改善作物生长和减轻氧化应激。 | Abdul Latif KHAN Syed Abdullah GILANI Muhammad WAQAS Khadija AL-HOSNI Salima AL-KHIZIRI Yoon-Ha KIM Liaqat ALI Sang-Mo KANG Sajjad ASAF Raheem SHAHZAD Javid HUSSAIN In-Jung LEE Ahmed AL-HARRASI | 2017 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2017，18，2： | 6 |
| 2 | Regime specific spillover across cryptocurrencies and the role of COVID‑19显示文摘The aim of this study is to examine the daily return spillover among 18 cryptocurrencies under low and high volatility regimes,while considering three pricing factors and the effect of the COVID-19 outbreak.To do so,we apply a Markov regime-switching(MS)vector autoregressive with exogenous variables(VARX)model to a daily dataset from 25-July-2016 to 1-April-2020.The results indicate various patterns of spillover in high and low volatility regimes,especially during the COVID-19 outbreak.The total spillover index varies with time and abruptly intensifies following the outbreak of COVID-19,especially in the high volatility regime.Notably,the network analysis reveals further evidence of much higher spillovers in the high volatility regime during the COVID-19 outbreak,which is consistent with the notion of contagion during stress periods. | Syed Jawad Hussain Shahzad Elie Bouri Sang Hoon Kang Tareq Saeed | 2021 | Financial Innovation2021，7，1： | 3 |
| 3 | Optical coherence tomography characteristics of responses to intravitreal bevacizumab in idiopathic choroidal neovascularization显示文摘AIM: To investigate factors associated with responses to intravitreal bevacizumab(IVB) in naive idiopathic choroidal neovascularization(i CNV) by high domain optical coherence tomography(OCT).·METHODS: We retrospectively reviewed clinical data of40 eyes of i CNV patients who received a single or multiple IVB on an as-needed basis(1.25 mg/0.05 m L).One month after the first injection, subretinal fluid(SRF)volume was evaluated and the eyes were divided into 3groups based on responses to IVB. Good, moderate, and poor responses were defined as 61%-99%, 30%-60%,and <30% resolution of SRF on OCT after IVB in i CNV,respectively. OCT findings were analyzed to find factors associated with difference in response levels.Comparisons were made using Wilcoxon's matched-pairs signed-rank test, the Mann-Whitney U test for means with continuous data and Fisher's exact test for categorical data.·RESULTS: The mean number of IVB was 1.28±1.50 and mean follow up time was 3.60 ±1.20 mo. At postoperative1 mo, there were 8(20%) eyes in good response, 20(50%)in moderate response and 12(30%) eyes in poor response group and at last visit there were 28 good responders(70%), 8(20%) moderate responders and 4(10%) poor responders. Statistically significant difference was detected between good responders and non good responders in choroidal neovessels thickness(P =0.029),SRF height(P =0.049) and SRF volume(P =0.031) at post treatment 1mo.· CONCLUSION: OCT is a valuable diagnostic tool.Decrease in choroidal neovessels thickness, SRF height and volume predicts favorable response of i CNV to IVB therapy. | Syed Nasir Ali Shah Qian-Yan Kang Xiao-Juan Fan Yue-Ming Sun | 2016 | International Journal of Ophthalmology(English edition)2016，9，2： | 2 |
| 4 | Impact and risk factors of post-stroke bone fracture显示文摘Bone fracture occurs in stroke patients at different times during the recovery phase, prolonging recovery time and increasing medical costs. In this review, we discuss the potential risk factors for post-stroke bone fracture and preventive methods. Most post-stroke bone fractures occur in the lower extremities, indicating fragile bones are a risk factor. Motor changes, including posture, mobility, and balance post-stroke contribute to bone loss and thus increase risk of bone fracture. Bone mineral density is a useful indicator for bone resorption, useful to identify patients at risk of post-stroke bone fracture. Calcium supplementation was previously regarded as a useful treatment during physical rehabilitation. However, recent data suggests calcium supplementation has a negative impact on atherosclerotic conditions. Vitamin D intake may prevent osteoporosis and fractures in patients with stroke. Although drugs such as teriparatide show some benefits in preventing osteoporosis, additional clinical trials are needed to determine the most effective conditions for post-stroke applications. | Kang Huo Syed I Hashim Kimberley LY Yong Hua Su Qiu-Min Qu | 2016 | World Journal of Experimental Medicine2016，6，1： | 2 |
