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...

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...

MicroRNA (miRNA)-153 (miR-153) has been considered as a novel tumor-related miRNA and is found to be significantly deregulated in human cancers. In this study, we found that the expression levels of miR-153 were obviously lower in gastric cancer tissues than those in matched adjacent nontumor tissues. Otherwise, miR-153 was expressed at significantly lower levels in aggressive tumor tissues. Cl...

introduction: developing new radiosynovectomy agents is of great importance due to the aging of human populations around the world and increasing the incidence of inflammatory diseases. in this work, sm-153 chitosan agent was developed for the first time in our country and preparation and quality control of the compound is described. methods: sm-153 chloride was obtained by thermal neutron flu...
