| 1 | Extraction, identification, and antioxidant property evaluation of limonin from pummelo seeds显示文摘Limonin, the main bioactive phytochemical constituent of limonoids with multi-functions, is enriched in citrus fruits and often found at a high concentration in citrus seeds. The present study was attempted to introduce a new and efficient extraction method to isolate limonoids from pummelo seeds, and to evaluate the antioxidant property of the main constituent limonin in Hep G2 cells. Three key single factors were identified for the extraction of limonoids from pummelo seeds using the Box-Behnken experiment design of response surface methodology(RSM), and the optimized extraction parameters were treatment with 89.68 m L of anhydrous acetone for 4.62 h at 78.94C, while the yield of limonoids was 11.52 mg/g. The structure of isolated main constituent of the limonoids was further identified as limonin by Fourier transform infrared(FT-IR) spectrometer and nuclear magnetic resonance(NMR)spectrum. Moreover, the molecular data in Hep G2 cells revealed that limonin exerted its anti-oxidant property mainly by the activation of nuclear factor(erythroid-2)-like 2(Nrf2)/kelch-like ECHassociated protein 1(Keap1)-antioxidant response element(ARE) pathway in the form of transcriptional regulation of Nrf2 m RNA and posttranscriptional regulation of Nrf2/Keap1 system. These results demonstrate that pummelo seeds are an ideal source of limonoids, and limonin is proved to exert its anti-oxidant property by the activation of Nrf2/Keap1 pathway. | Si Qin Chenghao Lv Qingshan Wang Zhibing Zheng Xi Sun Minyi Tang Fangming Deng | 2018 | Animal Nutrition2018，，3： | 10 |
| 2 | In-situ growth of Ni nanoparticle-encapsulated N-doped carbon nanotubes on carbon nanorods for efficient hydrogen evolution electrocatalysis显示文摘Searching for inexpensive,efficient and durable electrocatalysts with earth-abundant elements toward the hydrogen evolution reaction(HER)is of vital importance for the future sustainable hydrogen economy,yet still remains a formidable challenge.Herein,a facile template-engaged strategy is demonstrated for the direct in-situ growth of Ni nanoparticles and N-doped carbon nanotubes on carbon nanorod substrates,forming a hierarchically branched architecture(abbreviated as Ni@N-C NT/NRs hereafter).The elaborate construction of such unique hierarchical structure with tightly encapsulated Ni nanoparticles and open configuration endows the as-fabricated Ni@N-C NT/NRs with abundant well-dispersed active sites,enlarged surface area,reduced resistances of charge transfer and mass diffusion,and reinforced mechanical robustness.As a consequence,the optimal Ni@N-C NT/NR catalyst demonstrates superior electrocatalytic activity with relatively low overpotential of 134 mV to deliver a current density of 10 mA·cm^-2 and excellent stability for HER in 0.1 M KOH,holding a great promise for practical scalable H2 production.More importantly,this work offers a reliable methodology for feasible fabrication of robust high-performance carbon-based hierarchical architectures for a variety of electrochemical applications. | Xiaoxiao Yan Minyi Gu Yao Wang Lin Xu Yawen Tang Renbing Wu | 2020 | Nano Research2020，13，4： | 4 |

| 4 | OsPEX1,a leucine-rich repeat extensin protein,functions in the regulation of caryopsis development and quality in rice显示文摘Rice caryopses are enclosed by outer glumes.The size and dimension of the outer glume are the main determinants of caryopsis size.However,it is unclear whether caryopsis development is completely dependent on the size of the glume,or whether it can grow and expand autonomously despite the constraint of glume enclosure.We report the identification of a mutant line that produces normal-sized glumes with smaller mature caryopses that do not fill the entire glume cavity.The caryopsis phenotype in the pex1 mutant is caused by a reduction in cell size.Os PEX1,a leucine-rich repeat extensin gene,was highly expressed in the developing caryopsis.Overexpression of Os PEX1 driven by a constitutive promoter recapitulated the mutant phenotype,showing that the small-caryopsis phenotype is caused by overexpression of the Os PEX1 gene.Free amino acids,including several essential amino acids,and crude protein were increased in pex1 relative to the wild type,endowing pex1 with improved nutritional quality.Our results suggest that caryopsis development can be genetically uncoupled from maternally controlled glume development and that Os PEX1 might be a new resource for improving nutritional quality of rice cultivars. | Xin Luan Shanwen Ke Shuchun Liu Guojian Tang Dahui Huang Minyi Wei Yuexiong Zhang Gang Qin Xiang-Qian Zhang | 2022 | The Crop Journal2022，10，3： | 1 |
