Replicating retroviral vectors for oncolytic virotherapy of experimental hepatocellular carcinoma.

Gene therapy mediated by murine leukemia virus (MLV)-based replicating retrovirus vector (RRV) was previously proven to be highly effective in tumor cell killing, resulting in significant suppression of tumor growth in vivo. Recently, we developed a different form of RRV which is derived from another retrovirus, gibbon ape leukemia virus (GALV), as a cancer therapeutic agent. We compared the gene delivery efficiency and antitumor effects in the two types of RRV in experimental hepatocellular carcinoma (HCC).

Enhancement of mercury capture by the simultaneous addition of hydrogen bromide (HBr) and fly ashes in a slipstream facility.

Low halogen content in tested Powder River Basin (PRB) coals and low loss of ignition content (LOI) in PRB-derived fly ash were likely responsible for higher elemental mercury content (averaging about 75%) in the flue gas and also lower mercury capture efficiency by electrostatic precipitator (ESP) and wet-FGD. To develop a cost-effective approach to mercury capture in a full-scale coal-fired utility boiler burning PRB coal, experiments were conducted adding hydrogen bromide (HBr) or simultaneously adding HBr and selected fly ashes in a slipstream reactor (0.152 x 0.

A Wireless Physiological Signal Monitoring System with Integrated Bluetooth and WiFi Technologies.

This paper proposes a wireless patient monitoring system which integrates Bluetooth and WiFi wireless technologies. A wireless portable multi-parameter device was designated to acquire physiological signals and transmit them to a local server via Bluetooth wireless technology. Four kinds of monitor units were designed to communicate via the WiFi wireless technology, including a local monitor unit, a control center, mobile devices (personal digital assistant; PDA), and a web page.
