Field experiments were conducted for two years to investigate the benefits of alternate furrow irrigation on fruit yield, quality and water use efficiency of grape （Vitis vinifera L. cv. Rizamat） in the arid region of Northwest China. Two irrigation treatments were included, i.e., conventional furrow irrigation （CFI, two root-zones were simultaneously irrigated during the consecutive irrigation） and alternate partial root-zone furrow irrigation （AFI, two root-zones were alternatively irrigated during the consecutive irrigation）. Results indicate that AFI maintained similar photosynthetic rate （Pn） but with a reduced transpiration rate when compared to CFI. As a consequence, AFI improved water use efficiency based on evapotranspiration （WUEEr, fruit yield over water consumed） and irrigation （WUE~, fruit yield over water irrigated） by 30.0 and 34.5%, respectively in 2005, and by 12.7 and 17.7%, respectively in 2006. AFI also increased the edible percentage of berry by 2.91-4.79% significantly in both years. Vitamin C （Vc） content content of berry was increased by 25.6-37.5%, and tritrated acidity （TA） was reduced by 9.5-18.1% in AFI. This resulted in an increased total soluble solid content （TSS） to TA ratio （TSS/TA） by 11.5-16.7% when compared to CFI in both years. Our results indicate that alternate furrow irrigation is a practical way to improve grape fruit quality and water use efficiency for irrigated crops in arid areas.

Cyclopeptidomimetics are class of cyclopeptides with unnatural linkage. They usually displayed unique constrained structure, enhanced proteolytic stability, and other drug-like character; and have been widely used in medicinal chemistry. Therefore, development of efficient strategies for the synthesis of cyclopeptidomimetics has received many attentions. On-resin cyclization strategy is one of the effective approaches developed to overcome the competing side reaction such as oligomerization and cyclooligomers occurred in solution cyclization. This approach took advantage of the ＂pseudo-dilution＂ effect to avoid these undesired by-products and greatly simplified the downstream product purification process. This review summarized the recent on-resin peptide cyclization strategies for the synthesis of cvclooeotidomimetics.

Magnesium hydride nanoparticles anchored on MXene sheets as high capacity anode for lithium-ion batteries

引用

Journal of Energy Chemistry 2021年第11期30卷 431-439,I0009页

作者： Shulin zhong Shunlong Ju Yifei shao Wei Chen Tengfei zhang Yuqin Huang Hongyu zhang Guanglin Xia Xuebin Yu Department of Materials Science Fudan UniversityShanghai 200433China Jiangsu Key Laboratory of Electrochemical Energy-Storage Technologies College of Materials Science and TechnologyNanjing University of Aeronautics and AstronauticsNanjing 210016JiangsuChina Institute for Superconducting and Electronic Materials University of WollongongWollongongNSW 2522Australia

Magnesium hydride, with high specific capacity, favorable voltage profile and low voltage hysteresis properties, is regarded as a promising anode for lithium storage. However, the rapid fading of capacity caused by huge volume change, low electron/ion conduction, and spontaneous agglomeration of active materials during cycling greatly limit its practical application in lithium-ion batteries. Herein, we report the synthesis of monodisperse MgH2 nanoparticles with an average particle size of <20 nm homogeneously anchored on Ti3C2 MXene sheets by bottom-up self-assembly strategy. The unique nanoarchitectures are able to efficiently enhance the lithium insertion/extraction kinetics, accelerate the electron/lithium ion transfer and buffer the strain of volume changes. More importantly, the formed F–Mg bounding between MgH2 and MXene could avoid the shedding of MgH2 nanoparticles to electrolyte during cycling, which significantly enhance the capacity, cyclability, and rate performance of magnesium hydride. Moreover, due to the high density of MXene and the synergistic effect between the MgH2 and MXene matrix, the MgH2/MXene composite with 60 wt% MgH2 delivers a superior volumetric capacity of 1092.9 mAh cm−3 at a current density of 2000 mA g^(−1) after 1000 cycles. These results highlight the great promising of MgH2/MXene composite for high performance lithium-ion batteries.

Phototheranostic with highly integrated functions is an attractive platform for cancer management. It remains challenging to develop a facile phototheranostic platform with complementary bimodal imaging and combinational therapy capacity. Herein, the small-molecule cyanine IR780 loaded liposomes have been harnessed as a nanoplatform to simultaneously realize photoacoustic(PA)/the second near-infrared window(NIR-Ⅱ) fluorescence imaging and image-guided surgery/adjuvant photothermal therapy(PTT).This nanoplatform exhibits attractive properties like uniform controllable size, stable dispersibility, NIR-Ⅱ fluorescence emission, photothermal conversion, and biocompatibility. Benefiting from the complementary PA/NIR-Ⅱ fluorescence bimodal imaging, this nanoplatform was successfully applied in precise vasculature delineation and tumor diagnosis. Interestingly, the tumor was clearly detected by NIR-Ⅱ fluorescence imaging with the highest tumor-to-normal-tissue ratio up to 12.69, while signal interference from the liver was significantly reduced, due to the difference in the elimination rate of the nanoplatform in the liver and tumor. Under the precise guidance of the image, the tumor was accurately resected, and the simulated residual lesion after surgery was completely ablated by adjuvant PTT. This combined therapy showed improved antitumor efcacy over the individual surgery or PTT. This work develops a facile phototheranostic nanoplatform with great significance in accurately diagnosing and effectively treating tumors using simple NIR light irradiation.

Investigation of plant morphological features, pollen, and habitat have been made for two shrub species from Barrow, Alaska, namely Dryas integrifoila M. Vahl and Salix rotundifolia Trautv., both of which are endemic to the Arctic floristic area. The former species has small lanceolate or plate leaves, whereas the latter has rounded leaves with distinct veins, rich in vitamin C. Both have dwarf and sprawling habits. Pollen studies showed that the pollen grains of the two species are spheroidal to sub-spheroidal or prolate. The type of aperture was tricolporate; pollen size 26.3-31.3 μm; ornamentation finely reticulate under a light microscope （LM） and strlate-reticulate under a scanning electron microscope （SEM） for D. integrafoila and finely reticulate under the LM and SEM for S. rotundifolia. Comparisons were made between the pollen from the same species from Arctic collections with those from China and Japan. Investigation of pollen morphology of tundra plants can provide significant data for comparative studies of fossil pollen and for the reconstruction of paleovegetation and paleoclimate in the Barrow area.

Case Report:Surgical intervention of severe post-ERCP-pancreatitis accompanied with duodenum perforation

引用

Journal of Zhejiang University-Science B(Biomedicine & Biotechnology) 2010年第1期11卷 17-21页

作者： Zuo-bing CHEN zhong-yan LIANG Yun zhang shao-yang zhang Shu-sen ZHENG Department of Emergency Surgery the First Affiliated Hospital School of Medicine Zhejiang University Hangzhou 310003 China Department of Hepatopancreatobiliary Surgery the First Affiliated Hospital School of Medicine Zhejiang University Hangzhou 310003 China

Endoscopic retrograde cholangiopancreatography (ERCP) is a procedure widely used to diagnose and treat conditions of biliary or pancreatic ductal system. The post-ERCP severe acute pancreatitis (SAP) accompanied with duodenum perforation is rare but serious, remaining a challenge in clinic. In this study we report two such cases. Two Chinese women were treated for clinical suspicion of bile duct obstruction and underwent ERCP after admission. Both developed duodenum perforation and SAP after ERCP, and were managed in the intensive care unit (ICU) and required an organ-failure support. The surgical intervention of the peri-pancreatic debridement with lumber-abdominal compound incisions and postoperative washing and drainage was performed, and the two patients recovered well. The therapeutic effect of the peri-pancreatic debridement with lumber-abdominal compound incisions combined with postoperative washing and drainage in the patients of severe post-ERCP-pancreatitis (PEP) and duodenum perforation is satisfactory.
