| 1 | Increased Vitamin C Content Accompanied by an Enhanced Recycling Pathway Confers Oxidative Stress Tolerance in Arabidopsis显示文摘Vitamin C(L-ascorbic acid,AsA) has important antioxidant and metabolic functions in both plants and animals.Once used,ascorbic acid can be regenerated from its oxidized form in a reaction catalyzed by dehydroascorbate reductase(DHAR,EC 1.8.5.1).To analyze the physiological role of DHAR catalyzing the reduction of DHA to ascorbate in environmental stress adaptation,we examined whether increasing the level of AsA through enhanced AsA recycling would limit the deleterious effects of oxidative stress.A chimeric construct consisting of the double CaMV35S promoter fused to the Myc-dhar gene was introduced into Arabidopsis thaliana.Transgenic plants were biochemically characterized and tested for responses to oxidative stress.Western blot indicated that the dhar-transgene was successfully expressed.In homozygous T4 transgenic seedlings,DHAR overexpression was increased up to 1.5 to 5.4 fold,which enhanced foliar ascorbic acid levels 2-to 4.25-fold and ratio of AsA/DHA about 3-to 16-fold relative to wild type.In addition,the level of glutathione,the reductant used by DHAR,also increased as did its redox state.When whole plants were treated with high light and high temperature stress or in vitro leaf discs were subjected to 10 μM paraquat,transgenic plants showed a larger AsA pool size,lower membrane damage,and a higher level of chlorophyll compared with controls.These data suggested that increasing the plant vitamin C content through enhanced ascorbate recycling could limit the deleterious effects of environmental oxidative stress. | zinan wang Ying Xiao Wansheng Chen Kexuan Tang Lei Zhang | 2010 | Journal of Integrative Plant Biology2010,52,4: | 16 |

| 3 | DYNAMIC PRICING UNDER TEMPERATURE CONTROL FOR PERISHABLE FOODS显示文摘Consumers pay more and more attention to the quality of perishable foods,which is mainly affected by storage temperature.This paper presents a dynamic pricing model for perishable foods under temperature control.To maximize the total profit,the optimal price and storage temperature are obtained using Pontryagin's maximum principle.A static pricing model is provided to compare with the dynamic one.It is shown by a numerical example that the dynamic policy can make more revenue than the static one.Moreover,the managerial implications are analyzed and the effectiveness of the proposed method is demonstrated. | Wenwen Liu Wansheng Tang Lin Feng Jianxiong Zhang | 2014 | Journal of Systems Science and Systems Engineering2014,23,3: | 3 |
| 4 | The transcription factors TLR1 and TLR2 negatively regulate trichome density and artemisinin levels in Artemisia annua显示文摘The important antimalarial drug artemisinin is biosynthesized and stored in Artemisia annua glandular trichomes and the artemisinin content correlates with trichome density;however,the factors affecting trichome development are largely unknown.Here,we demonstrate that the A.annua R2R3 MYB transcription factor TrichomeLess Regulator 1(TLR1)negatively regulates trichome development.In A.annua,TLR1 overexpression lines had 44.7%–64.0%lower trichome density and 11.5%–49.4%lower artemisinin contents and TLR1-RNAi lines had 33%–93.3%higher trichome density and 32.2%–84.0%higher artemisinin contents compared with non-transgenic controls.TLR1 also negatively regulates the expression of anthocyanin biosynthetic pathway genes in A.annua.When heterologously expressed in Arabidopsis thaliana,TLR1 interacts with GLABROUS3a,positive regulator of trichome development,and represses trichome development.Yeast two-hybrid and pull-down assays indicated that TLR1 interacts with the WUSCHEL homeobox(WOX)protein AaWOX1,which interacts with the LEAFY-like transcription factor TLR2.TLR2 overexpression in Arabidopsis and A.annua showed that TLR2 reduces trichome development by reducing gibberellin levels.Furthermore,artemisinin contents were 19%–43%lower in TLR2-overexpressing A.annua plants compared to controls.These data indicate that TLR1 and TLR2 negatively regulate trichome density by lowering gibberellin levels and may enable approaches to enhance artemisinin yields. | Zongyou Lv JinXing Li Shi Qiu Fei Qi Hang Su Qitao Bu Rui Jiang Kexuan Tang Lei Zhang Wansheng Chen | 2022 | Journal of Integrative Plant Biology2022,64,6: | 2 |

| 15 | Percutaneous transhepatic intrahepatic portosystemic shunt for variceal bleeding: A series of six cases and literature review显示文摘Objectives:To present a case series of modified transjugular intrahepatic portosystemic shunts(TIPS) and percutaneous transhepatic intrahepatic portosystemic shunts(PTIPS) in cirrhotic patients with variceal bleeding(VB).In addition,the scientific literature pertaining to PTIPS was reviewed.Methods:This retrospective clinical case series included six cirrhotic patients with VB who were treated with PTIPS after the failure of endoscopic band ligation or endoscopic injection sclerotherapy combined with vasoactive drugs.The treatment was conducted between January 2017 and June 2019 at a single institution.Three patients suffered from severe atrophy of the right or left lobar of the liver as well as the main right or left branch of the portal vein.The remaining three patients showed severe atrophy of the whole liver and portal vein,resulting in widening of the liver fissure.A paired t-test was used to compare the changes in portal pressure gradient between before and after the PTIPS operation.The rebleeding rate,treatment efficacy,complications,and technical success rate were all assessed during follow-up.Results:All six PTIPS procedures were performed successfully,with no severe procedural-related complications observed.None of the patients experienced VB during a mean follow-up of 22.8(range,18.0-28.0) months.The mean portosystemic pressure gradient decreased from 28.3 ± 4.3 mmHg pre-procedure to 12.3 ± 2.6 mmHg immediately post-procedure(P <0.001).At follow-up,one patient was found to have developed grade 2 hepatic encephalopathy thrice during the first year,according to the West Haven criteria.However,this was resolved following medical treatment.Conclusions:When the patient’s portal venous anatomy is unconducive to the performance of TIPS using the transjugular approach,PTIPS can be considered as a safe,effective complementary surgical approach for patients with VB. | Hang Du Binyan Zhong Peng Zhang Wansheng Wang Jian Shen Shuai Zhang Wanci Li Haohuan Tang Linfeng Zhou Weihao Yang Xiaoli Zhu | 2021 | Journal of Interventional Medicine2021,4,1: | 1 |
