The

effects of composition of spinning casting solution and process parameters see more of dry-wet spinning on the structure of hollow fiber matrix membrane were investigated. Through the reaction between matrix membrane and thiourea, the highly qualified polysulfonebenzylthiourea reactive hollow fiber ultrafiltration membranes were able to afford. The adsorption isotherms of the polysulfonebenzylthiourea hollow fiber membrane for Cd(2+) and Zn(2+) were determined and the effects of mobile phase conditions and the operating parameters on removal performance of the polysulfonebenzylthiourea hollow fiber membrane for Cd(2+) and Zn(2+) were also investigated. The experimental results showed that adsorption isotherms of Cd(2+) and Zn(2+) could be described by the Langmuir isotherm, the polysulfonebenzylthiourea hollow fiber membrane could be operated at high feed flow rate, and a large-scale removal of Cd(2+) and Zn(2+) could be realized. According to required recovery of Cd(2+) and Zn(2+) and the saturation degree of polysulfonebenzylthiourea hollow fiber membrane, the optimum loading amount of Cd(2+) and Zn(2+) should be selected in the actual removal of Cd(2+) and Zn(2+).

“Pure amorphous carbon (a-C) film

and that with a learn more small amount of Ti were deposited on high speed steel (W18Cr4V) substrates by means of dc closed field unbalanced magnetron sputtering. The chemical composition and microstructure of the a-C films were performed using x-ray photoelectron spectroscopy, x-ray diffraction, Raman spectra, and transmission electron microscopy. The mechanical and tribological properties were evaluated using a nanoindentor, Rockwell and scratch tests, and a conventional ball-on-disk CYT387 tribometer, respectively. The pure a-C film showed the high hardness (53 GPa), elastic modulus (289 GPa), but the poor adhesive strength. When adding a small amount of Ti to the a-C film, both the adhesive strength and the tribological properties

were improved. The Ti contained a-C film had the low wear rate (1.9×10(-17) m(3) N(-1) m(-1)) and friction coefficient in humid air.”
“Background: Lung cancer is the most common cause of cancer-related death in the United States, yet traditional chemotherapy fails to provide long-term benefit for many patients. New approaches are needed to improve overall survival beyond the current standard of care.

Methods: This review discusses recent clinical trials using immunotherapy techniques to treat both non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC) and highlights ongoing immunotherapy research efforts at our center.

Results: For NSCLC, phase II clinical trials have examined allogeneic vaccines that target either mucin 1 (MUC1), epidermal growth factor or melanoma-associated antigen 3. These vaccines are now undergoing larger phase III trials.
