Human exposure to pollutants from e-waste is an important scientific issue for their health effects. In this study, organohalogen pollutants in human serum sample from an e-waste dismantling site (n=35) and a control site (n=21), both located in Tianjin, Northern China, were analyzed using GC-ECNI-MS. Geometric mean concentrations of tetra- through hexa-BDEs, hepta- through nona-BDEs, PCBs, PBB...

Background: Oxidants and inflammation agents are predisposing factors for the development of prostate cancer. As a chemical warfare, sulfur mustard (SM) can cause cancer through various pathways mainly increased production of oxidants and inflammation. Due to high incidence of cancer in SM victims, concentration of prostate specific antigen (PSA) in SM victims was evaluated and compared with th...

UNLABELLED All lanthanides have similar chemical properties regarding labeling. Therefore, radiolanthanides that have been used for therapy, such as (153)Sm and (177)Lu, might easily be replaced with other radiolanthanides. The aim of this work was to investigate the suitability of electron- and positron-emitting radiolanthanides for radionuclide therapy with reference to dosimetry and producti...

The effects of two 8 week programmes of reconditioning in chronic obstructive pulmonary disease (COPD) patients were studied. Forty one subjects (mean+/-SD) 644.5) yrs; forced expiratory volume in one second (FEV1) 1.09+/-0.16 L; 40.6+/-6.2% predicted were randomly assigned either to supervised training on a treadmill, 4 days x week(-1) (group S; n=21) or walking 3 or 4 km in 1 h 4 days x week(...

The protocol independent multicast-sparse mode (PIM-SM) protocol establishes core-base tree to forward multicast datagrams in a network. In PIM-SM, the core or rendezvous point (RP) of a group is determined at each multicast router by hashing a group address, i.e. a class-D IP address, to one of the candidate RPs. The hash function is characterized by its ability to evenly and uniquely choose t...

sulfur mustard (sm) is a chemical warfare agent which was widely used in the world war i and more recently during gulf war in the early 1980s'. sm is a strong alkylating agent with known mutagenic and carcinogenic effects but only few studies have been published on its teratogenicity. since sm has been widely used as a chemical weapon by the iraqi regime against the iranian soldiers as well as ...

Results Age at the time of anaphylactic reaction ranges from 1 month to 15 years (median age 37 months), with 71 patients younger than 3 years (46.4%). There is a male predominance representing 58.5% of the cases. The most commonly involved allergens are: peanut (31/153, 20.3%), tree nuts (31/153, 20.2%), cow’s milk (26/153, 17%), eggs (24/153, 15.7%), fish (9/153, 5.8%) and shellfish (8/153, 5...
