PURPOSE To identify prognostic factors associated with survival beyond 4 years and overall response in patients with metastatic melanoma treated with high-dose bolus i.v. interleukin-2 (IL-2) given either alone or in combination with a variety of melanoma vaccines. STUDY DESIGN 684 consecutive patients with metastatic melanoma received high-dose bolus i.v. IL-2 either alone or in conjunction ...
This study examines polybrominated diphenyl ethers (PBDE) levels, trends in biosolids from a wastewater treatment plant, and evaluates potential factors governing PBDE concentrations and the fate in agricultural soils fertilized by biosolids. The mean concentration of the most abundant PBDE congeners in biosolids ( summation operatorBDE-47, BDE-99, and BDE-209) generated by one wastewater treat...
Gaseous and size-segregated particulate PBDEs (specifically BDE-47, -99, -183, -207, and -209) in the air were measured in urban Guangzhou at 100 and 150 m above the ground in daytime and at night in August and December 2010, to assess dry deposition of these contaminants accurately with regards to influences of meteorological factors but without confounding surface effects. Particulate PBDEs w...
Indoor dust has been widely used to monitor flame retardants (FRs) in indoor environment, but most studies only focused on floor dust. In the present study, FRs were examined in indoor dust from different locations. Dust from air conditioner (AC) filters, beddings, floor, and windows in bedrooms, and dust from AC filters, printer table surface, computer table surface, floor, and windows in offi...

The present research was applied in terms of objective, and it was implemented using different approaches to examine the social health of rural women and its determinants in Kermanshah Province, Iran. The research method was ...
Ultra-pure, carrier-free (209)Po solution standards have been prepared and standardized for their massic alpha-particle emission rate. The standards, which will be disseminated by the National Institute of Standards and Technology (NIST) as Standard Reference Material SRM 4326a, have a mean mass of (5.169 ± 0.003) g of a solution of polonium in nominal 2.0 mol▪L(-1) HCl (having a solution densi...
