[Molecular mechanism of geniposide in regulating GLUT2 glycosylation in pancreatic β cells].

Type 2 diabetes mellitus( T2 DM) is a common chronic metabolic disease characterized by persistent hyperglycemia and insulin resistance. In pancreatic β-cells,glucose-stimulated insulin secretion( GSIS) plays a pivotal role in maintaining the balance of blood glucose level. Previous studies have shown that geniposide,one of the active components of Gardenia jasminoides,could quickly regulate the absorption and metabolism of glucose,and affect glucose-stimulated insulin secretion in pancreatic β cells,but the specific mechanism needs to be further explored.

[Haze Spectral Analysis and Detection Algorithm Using Satellite Remote Sensing Data].

Frequent occurring of haze pollution events and high fine particulate matter (PM(2.5)) concentration in China have attracted more and more attention in the world. Satellite remote sensing can be used to characterize the air pollution.

[Estimating Biomass Burned Areas from Multispectral Dataset Detected by Multiple-Satellite].

Biomass burning makes up an important part of both trace gases and particulate matter emissions, which can efficiently degrade air quality and reduce visibility, destabilize the global climate system at regional to global scales. Burned area is one of the primary parameters necessary to estimate emissions, and considered to be the largest source of error in the emission inventory. Satellite-based fire observations can offer a reliable source of fire occurrence data on regional and global scales, a variety of sensors have been used to detect and map fires in two general approaches: burn scar mapping and active fire detection.

[A quickly atmospheric correction method for HJ-1 CCD with deep blue algorithm].

In the present, for the characteristic of HJ-1 CCD camera, after receiving aerosol optical depth (AOD) from deep blue algorithm which was developed by Hsu et al. assisted by MODerate-resolution imaging spectroradiometer (MODIS) surface reflectance database, bidirectional reflectance distribution function (BRDF) correction with Kernel-Driven Model, and the calculation of viewing geometry with auxiliary data, a new atmospheric correction method of HJ-1 CCD was developed which can be used over vegetation, soil and so on. And, when the CCD data is processed to correct atmospheric influence, with look up table (LUT) and bilinear interpolation, atmospheric correction of HJ-1 CCD is completed quickly by grid calculation of atmospheric parameters and matrix operations of interface define language (IDL).

[The monitoring of haze from HJ-1].

With the urbanizing in China, haze days occur frequently, which have largely impacted air quality. In the present paper, based on haze physical properties, haze optical properties were calculated by Mie theory and apparent reflectance of haze in Environment Satellite 1 (HJ-1) channels was simulated by Radiative Transfer (RT) 3. Simulated results show that it is reasonable to extract the haze from apparent reflectance in the first and second channels.

[The retrieval of fine and coarse aerosol from MODIS].

Generally, aerosols over land are composed of fine and coarse aerosols, which have different optical properties. How to derive the fine mode and coarse mode aerosols from satellite observations is an important issue in the aerosol retrieving. In the present paper, information of aerosol models (including refractive index and size distribution function) was retrieved from the ground-based measurement of the AERONET/PHOTONS site in Beijing.

[Retrieval and validation of the surface reflectance using HJ-1-CCD data].

The potentiality of the retrieval of surface reflectance using CCD camera aboard HJ-1A/B satellite was studied. It is very difficult to use dark targets in atmospheric correction due to the lack of near infrared band. The alternative normalized difference vegetation index (NDVI) and the red/blue reflectance ratio are detected from the spectral experiment in Beijing and the Pearl River Delta.

[Level and characteristics of indoor air pollutants in a furniture mall in Beijing].

Concentrations of BTX (benzene, toluene and xylene), total volatile organic compounds (TVOC), formaldehyde and other carbonyl compounds were measured in different sections of a furniture mall in Beijing. The overall indoor concentrations (mean +/- standard deviation) of formaldehyde, benzene, toluene, xylene, and TVOC were (0.37 +/- 0.

[Usability of the laboratory report and knowledge of lipid-lowering in out-patients from dyslipidemia-related departments].

Objective: To investigate the usability of laboratory test report from the angle of patients and understand to what degree the patients master the knowledge of lipid-lowering.

Methods: A total of 508 outpatients, selected from a Grade III-A general hospital, were queried by a questionnaire, their medical records and test reports were reviewed and their heights and weights were measured. In the study, 431 of them fulfilled the inclusion criteria and their information about lipid lowering treatment and treatment compliance were collected.

[Study for differential cross section of ring effect].

The Ring effect is a significant limitation to the accuracy of the retrieval of trace gas constituents in atmosphere, while using satellite data with differential optical absorption spectroscopy technique. The Ring effect refers to the filling in of Fraunhofer lines, known as solar absorption lines, caused almost entirely by rotational Raman scattering. The inelastic component of the molecular scattering results in a net increase in radiance in the line because more radiation is shifted to the wavelength of an absorption line than shifted from this wavelength to other wavelengths.
