  • Fur apparel is a representative luxury item that displays wealth and social status; however, it is also recognized as an unethical product criticized for its animal maltreatment in the production process. Understanding consumer responses to an ambivalent object, such as fur apparel, is an important research topic both academically and practically. This study investigates the hierarchical effects of perceived benefits and risks of fur apparel on consumers' emotions and purchase intention by applying the ABC model of attitudes to identify the mediating effects of consumer emotions. An online survey was conducted on 390 female consumers that verified hypotheses through structural equation modeling and bootstrapping analysis using phantom variables. The initial results of the survey showed that the relationship between perceived conspicuous benefits and purchase intention towards fur apparel was partially mediated by positive emotion. Second, the relationship between perceived epistemic benefits and purchase intention was completely mediated by positive emotion. Third, the relationship between perceived ethical risk and purchase intention was completely mediated by positive and negative emotions. Fourth, perceived social risk did not affect the purchase intention of fur apparel significantly. The results support that cognitive beliefs about the subject have a significant positive effect on behavioral intentions through emotions as suggested in the ABC model of the attitude. This study provides an in-depth understanding of consumer responses to ambivalent objects by revealing the individual mediating effects of consumers' positive and negative emotions.

  • Background: To investigate the effects of ASMase mediated endothelial cell apoptosis in multiple hypofractionated irradiations in CT26 tumor bearing mice. Materials and Methods: Thirty-five CT26 tumor bearing mice were subjected to single ionizing radiation (IR) of 0, 3, 6, 9, 12, 15, 18 Gy. Eight hours after IR, the mice were sacrificed and tumor tissues were used for CD31 immunohistochemistry staining, TUNEL and CD31 double staining, ASMase activity assay. Then 6 and 12 Gy were chosen for multiple hypofractionated IR experiments according to the above results. Each time after IR, 5 mice were sacrificed and assayed as above. Results: The ASMase activities were increased significantly after a single IR of 12 Gy or higher which was accompanied with remarkable increased endothelial cell apoptosis and decreased MVD. For 6 Gy which was not high enough to trigger ASMase activation, after 2 or more times of IR, the ASMase activities were significantly increased accompanied with remarkable increased endothelial cell apoptosis and decreased MVD. While for 12 Gy, after 2 or more times of IR, the ASMase activities and endothelial cell apoptosis rates were maintained without remarkable increase; however, the MVD was significantly decreased. What's more, the cancer cell apoptosis rates were significantly increased after multiple IR for both 6 Gy and 12 Gy. Conclusions: ASMase mediated endothelial cell apoptosis may play an important role in the process of multiple hypofractionated IR for CT26 colorectal carcinoma.

  • This study explored mediating effects of the maternal emotional expressiveness between maternal behavioral inhibition/behavioral activation system and children's emotional intelligence. subjects were 138 4- to 5-year-old preschoolers (92 boys, 46 girls) and their mothers. The maternal behavioral inhibition/behavioral activation system was measured by BIS/BAS(Behavioral Inhibition System/Behavioral Activation System, Carver & White, 1994), maternal emotional expressiveness was measured by the Self-Expressiveness in the Family Questionnaire (Halberstadt, 1995), and children's emotional intelligence was measured by the Emotional Intelligence Questionnaire (Lee, 1998). Data were analyzed by descriptive statistics and multiple regression analysis. Results were that maternal positive expressiveness mediated the effects of maternal BIS on children's self-understanding and maternal negative expressiveness mediated the effects of maternal BAS on children's self-regulation.

  • IL-18 has been found to have multiple effects upon various cells involved in tumor immunology. Here, we discuss opposite effects of IL-18 in tumor immunology. IL-18 has been shown that it has significant anti-tumor effects, which are mediated by T cells and NK cells, in a manner similar to IL-12. First, we investigated the evaluation of the effects of the systemic administration of IL-18 in combination with B7-1 (CD80) against murine B16 melanoma in vivo. (omitted)
