Spatial distributions and environmentally-mediated factors of dimethylsulfoxide off the northern Antarctic Peninsula in summer.

Spatial distributions of dissolved and particulate dimethylsulfoxide (DMSOd and DMSOp) were investigated off the northern Antarctic Peninsula during the austral summer of 2018, an ecologically and climatically important region of the world. In the upper waters, DMSOd was concentrated in the ice-melt zone because DMSO functions physiologically as an intracellular osmolyte and cryoprotectant. DMSOd concentrations had a weak positive correlation with temperature but a negative correlation with nutrients.

Bevacizumab attenuates osteosarcoma angiogenesis by suppressing MIAT encapsulated by serum-derived extracellular vesicles and facilitating miR-613-mediated GPR158 inhibition.

Targeting angiogenesis has been considered a promising treatment for a large number of malignancies, including osteosarcoma. Bevacizumab (Bev) is an anti-vascular endothelial growth factor being used for this purpose. We herein investigate the therapeutic potential of Bev in angiogenesis during osteosarcoma and the related mechanisms.

Occurrence, distribution, and sea-air fluxes of volatile halocarbons in the upper ocean off the northern Antarctic Peninsula in summer.

We studied the spatial variations of six volatile halocarbons (VHCs), namely, iodomethane (CHI), chloroform (CHCl), tetrachloroethylene (CCl), bromodichloromethane (CHBrCl), dibromomethane (CHBr), and carbon tetrachloride (CCl), and the environmental influencing factors involved in the cycling of VHCs in the upper ocean (0-500 m) off the Northern Antarctic Peninsula (NAP) during the summer of 2018. About 5%-10% of the total biogenic VHCs in the upper ocean were accumulated in the assemblage layer (AL) with high chlorophyll a. However, higher VHCs levels were observed in the dicothermal layer (DL) compared with the AL because of the preservation from winter and production from dinoflagellates and chlorophytes.

Visible-Light Photocatalytic Activity of Fe and/or Ni Doped Ilmenite Derived-Titanium Dioxide Nanoparticles.

Pure TiO₂ nanoparticles and ones doped with Fe and/or Ni were successfully prepared by a co-precipitation method from ilmenite. The samples were structurally characterized by XRD, XPS, FT-IR, UV-vis, SEM, EDX, AAS and BET measurement. The XRD results showed that all samples were anatase TiO₂, and no characteristic peaks of dopants were observed.

[Distribution pattern and influencing factors of vegetation carbon storage of Tamarix chinense in the coastal wetland of Laizhou Bay, China].

The tamarisk shrub wetland located at the south of Laizhou Bay is the largest tamarisk area existing in the northern China, which is also the important part of the wetland ecological rehabilitation project 'Southern Mangrove Northern Tamarisk' in China. Based on the field data from Changyi National Marine Ecological Special Reserve surveyed in August 2014, we investigated the spatial patterns of vegetation, biomass, carbon content, and the associated environmental parameters in this area. The results showed that the average vegetation biomass and carbon storage were 949.

[Effect of health education intervention on schistosomiasis control in Mianyang City].

Objective: To evaluate the effect of health education on schistosomiasis control in Mianyang City.

Methods: The population aged 6-65 years in 12 moderately and heavy schistosomiasis endemic villages of 6 endemic counties in Mianyang City were selected as the investigation objects, among which, the health education on schistosomiasis control were implemented. The questionnaire surveys were carried out to understand the knowledge, attitude and behavior on schistosomiasis control of the target population, and the scores before and after the intervention were compared to evaluate the effect.

Infection of prions and treatment of PrP106-126 alter the endogenous status of protein 14-3-3 and trigger the mitochondrial apoptosis possibly via activating Bax pathway.

The 14-3-3 proteins are a family of highly homologous and ubiquitously expressed isoforms that are involved in a wide variety of physiological processes. 14-3-3 have showed actively molecular interaction with PrP and positive 14-3-3 is frequently observed in the cerebrospinal fluid (CSF) samples of the patients with sporadic Creutzfeldt-Jakob disease (CJD). However, the alterations of 14-3-3 in the brain tissues of patients with prion diseases remain little addressed.

[The 2A protease of enterovirus 71 cleaves nup62 to inhibit nuclear transport].

To study the impact of the enterovirus 71(EV71) on the nuclear transport mechanism,The pGFP-NLS vector with nuclear location signal(NLS) was constructed, RD cells transfected by the pGFP-NLS vector were inoculated with the EV71 or cotransfected by EV71-2A vector. The results showed that GFP protein with NLS was expressed in the cytoplasm due to the inhibition of nuclear transport. In order to further study the mechanism of the EV71 to prevent nuclear transport,Nup62 was detected by Western blotting after RD cells were infected with EV71 or transfected by EV71-2A vector.

[Research on determination of total volatile organic sulfur compounds in the atmosphere].

A detection technology was established comprising trap, desorption, oxidation and UV fluorescence determination process, and used for the test of total concentration of trace volatile sulfur compounds (VSCs) in the atmosphere. A cryogenic trap-thermal desorption device was developed, integrating the advantages of solid retention method and cryogenic condensation method, which was applied to capture and enrich trace volatile organic sulfur compounds. Under high temperature and combustion-supporting gas, the VSCs were completely oxidized into sulfur dioxide.
