[Functional analysis on sucrose transporters in sweet potato].

Sweet potato is an important food crop that can also be used as an industrial raw material. Sucrose is the main form of long-distance carbohydrate transport in plants, and sucrose transporter (SUT) regulates the transmembrane transport and distribution of sucrose during plant growth and metabolism. Moreover, SUT plays a key role in phloem mediated source-to-sink sucrose transport and physiological activities, supplying sucrose for the sink tissues.

Regulatory and functional divergence among members of , a sweet potato vacuolar invertase gene controlling starch and glucose content.

Sweet potato [ (L.) Lam.] is an important food and industrial crop.

IbInvInh2, a novel invertase inhibitor in sweet potato, regulates starch content through post-translational regulation of vacuolar invertase IbβFRUCT2.

As a key enzyme in the starch and sugar metabolic pathways in sweet potato (Ipomoea batatas (L.) Lam.), the vacuolar invertase (EC 3.

Optical confinement in the nanocoax: coupling to the fundamental TEM-like mode.

The nanoscale coaxial cable (nanocoax) has demonstrated optical confinement in the visible and the near infrared. We report on a novel nanofabrication process which yields optically addressable, sub-µm diameter, and high aspect ratio metal-insulator-metal nanocoaxes made by atomic layer deposition of Pt and AlO. We observe sub-diffraction-limited optical transmission via the fundamental, TEM-like mode by excitation with a radially polarized optical vortex beam.

Comparison of land surface and air temperatures for quantifying summer and winter urban heat island in a snow climate city.

The urban heat island (UHI) effect is an increasingly consequential problem that confronts cities. The accurate characterization and quantification of UHI are crucial for sustainable urban development. Few UHI studies, however, compare data source, spatio-temporal variations, and indicators for the same city in parallel.

Characterizing the Hourly Variation of Urban Heat Islands in a Snowy Climate City during Summer.

Temporal variation of urban heat island (UHI) intensity is one of the most important themes in UHI studies. However, fine-scale temporal variability of UHI with explicit spatial information is sparse in the literature. Based on the hourly air temperature from 195 meteorological stations during August 2015 in Changchun, China, hourly spatiotemporal patterns of UHI were mapped to explore the temporal variability and the effects of land use on the thermal environment using time series analysis, air temperature profiling, and spatial analysis.

Wireless communication system via nanoscale plasmonic antennas.

Present on-chip optical communication technology uses near-infrared light, but visible wavelengths would allow system miniaturization and higher energy confinement. Towards this end, we report a nanoscale wireless communication system that operates at visible wavelengths via in-plane information transmission. Here, plasmonic antenna radiation mediates a three-step conversion process (surface plasmon → photon → surface plasmon) with in-plane efficiency (plasmon → plasmon) of 38% for antenna separation 4λ0 (with λ0 the free-space excitation wavelength).

[Monitoring on spatial and temporal changes of snow cover in the Heilongjiang Basin based on remote sensing].

This paper extracted and verified the snow cover extent in Heilongjiang Basin from 2003 to 2012 based on MODIS Aqua and Terra data, and the seasonal and interannual variations of snow cover extent were analyzed. The result showed that the double-star composite data reduced the effects of clouds and the overall accuracy was more than 91%, which could meet the research requirements. There existed significant seasonal variation of snow cover extent.

Objective: To develop a method for determining the concentration of dichlorvos in serum by gas chromatography and to provide a basis for clinical diagnosis and monitoring of dichlorvos poisoning.

Methods: The serum (0.5 ml)collected from patients with dichlorvos poisoning was mixed with ethyl acetate (2.

[The impact of L-carnitine administration on the serum level of myocardium injury markers in patients with acute carbon monoxide poisoning].

Objective: To examine the serum level of myocardial injury markers in patients with carbon monoxide (CO) poisoning, the correlation between these markers and the severity of the disease, and the therapeutic effects of L-carnitine administration.

Methods: 69 patients, chosen from 309 cases of acute carbon monoxide poisoning (ACOP) for abnormally high level of serum myocardial injury markers (myoglobin, Mb; MB isoenzyme of creatine kinase, CK-MB; cardiac troponin-I, cTnI) at the time of admission, were randomly divided into control group (n = 34) and observation group (n = 35). The patients in control group were given Xingnaojing (20 ml/d i.
