BACKGROUND: The question of independent association between allogeneic blood transfusion (ABT) and postoperative complications in cancer surgeries has been controversial and remains so. In metastatic spine tumor surgery (MSTS), previous studies investigated the influence of ABT on survival, but not on postoperative complications. We aimed to evaluate the influence of perioperative ABT on postoperative complications and infections in patients undergoing MSTS. STUDY DESIGN AND METHODS: This retrospective study included 247 patients who underwent MSTS at a single tertiary institution between 2005 and 2014...

Chitosan-genipin films present a bluish-green color due to the conjugated double bonds formed when monomeric or dimeric genipin residues bridge chitosan. This phenomenon limits their use when colorless materials are required. In this work, a two-step oxidation strategy was developed aiming to remove color from chitosan-genipin films while preserving their functional properties. A combined system using the recombinant CotA laccase from Bacillus subtilis mediated by 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) followed by a H2O2 oxidation step was settled...

Wild-type p53 tumor suppressor activity in neuroblastoma tumors is hampered by increased MDM2 activity, making selective MDM2 antagonists an attractive therapeutic strategy for this childhood malignancy. Since monotherapy in cancer is generally not providing long-lasting clinical responses, we here aimed to identify small molecule drugs that synergize with idasanutlin (RG7388). To this purpose we evaluated 15 targeted drugs in combination with idasanutlin in three p53 wild type neuroblastoma cell lines and identified the BCL2 inhibitor venetoclax (ABT-199) as a promising interaction partner...

The ecotoxicology effects of chiral herbicides have long been recognized and have drawn increasing attention. The toxic mechanisms of herbicides in plants are involved in production of reactive oxygen species (ROS) and cause damage to target enzyme, but the relationship between these two factors in the enantioselectivity of chiral herbicides has rarely been investigated. Furthermore, even though cytochromes P450 enzymes (CYP450s) have been related to the phytotoxicity of herbicides, their roles in the enantioselectivity of chiral herbicides have yet to be explored...

Promising clinical efficacy has been observed with receptor tyrosine kinase inhibitors (TKIs) particularly in lung and gastric cancers with mutations or amplifications in the targeted receptor tyrosine kinases (RTKs). However, the efficacy and the duration of the response to these inhibitors are limited by the emergence of drug resistance. Here, we report treatment of RTK-dependent lung and gastric cancer cell lines with TKIs increased protein levels of Bcl-2 and Bcl-xL. The combination of the Bcl-2 and Bcl-xL inhibitor ABT-263 and TKIs was superior to TKIs alone in reducing cell viability and capacity of resistant colony formation...
