No full textFig. 4. Distribution of the main alkaloids in diverse tissue parts in the plant of C. lansium. All the MSI were acquired in positive ion mode. The number of pixels in x and y axis was 243 × 248 for the fruit, and 100 × 70 for the stem and 65 × 37 for the leaf parts. The distributions are displayed as heat maps, with the color code between black (low) and red (high). Images were exported from the Shimadzu Imaging software.

A dielectric-barrier discharge enhanced plasma brush array at atmospheric pressure
No full textThis study developed a large volume cold atmospheric plasma brush array, which was enhanced by a dielectric barrier discharge by integrating a pair of DC glow discharge in parallel. A platinum sheet electrode was placed in the middle of the discharge chamber, which effectively reduced the breakdown voltage and working voltage. Emission spectroscopy diagnosis indicated that many excited argon atoms were distributed almost symmetrically in the lateral direction of the plasma. The concentration variations of reactive species relative to the gas flow rate and discharge current were also examined. (C) 2013 AIP Publishing LLC
Chitosan and chitooligosaccharide regulated reactive oxygen species homeostasis at wounds of pear fruit during healing
No full textBoth chitosan (CTS) and chitooligosaccharide (COS) can promote fruit healing. However, whether the two chemicals regulate reactive oxygen species (ROS) homeostasis during wound healing of pear fruit remains unknown. In this study, the wounded pear fruit (Pyrus bretschneideri cv. Dongguo) was treated with a 1 g L-1 CTS and COS. We found CTS and COS treatments increased NADPH oxidase and superoxide dismutase activities, and promoted O2.- and H2O2 production at wounds. CTS and COS also enhanced the activities of catalase, peroxidase, ascorbate peroxidase, monodehydroascorbate reductase, dehydroascorbate reductase, and glutathione reductase, and elevated the levels of ascorbic acid and glutathione. In addition, the two chemicals improved antioxidant capacity in vitro and maintained cell membrane integrity at fruit wounds during healing. Taken together, CTS and COS can regulate ROS homeostasis at wounds of pear fruit during healing by scavenging excessive H2O2 and improving antioxidant capacity. Overall, the COS demonstrated superior performance over the CTS
Slowing Down DNA Translocation Through Solid-State Nanopores by Pressure
No full textThe effect of applied pressure on event duration distributions in 3 kb dsDNA translocation is systematically investigated. The effects of pressure magnitude and nanopore size on the length discrimination between 615 bp and 1.14 kbp dsDNA is studied. The pressure-controlled DNA translocation in solid-state nanopores makes a significant contribution to improve the temporal resolution in DNA single-molecule detection.Copyright ? 2013 WILEY-VCH Verlag GmbH & Co.
