The alpha -> beta polytypic transformation in SiC was observed during ball milling at room temperature. Microstructural evolution was characterized on an atomic scale by high-resolution electron microscopy (HREM). HREM observations showed that partial dislocations play an important role in the transformation under the complicated conditions during ball milling. 相似文献

Previous evidence had revealed gender differences in perception of pain and its socialization. The present research studies gender differences by mapping the central structure core in social representation of pain. Eighty males and eighty females participated in a free evocation task for collecting cognitive elements of “pain.” By defining the elements as nodes and their co‐occurrences as lines, structural characteristics of social representation are analyzed by network analysis. Females have a central structure core in their network structure of social representation of pain. In contrast, males have no such core. These results suggest gender differences in socialization processes around the concept of pain and extend practical methods for studies of the central nucleus theory of social representation. 相似文献

This study examined life event stress, perceived stress and psychiatric co-morbidity among patients with Chronic Idiopathic Urticaria (CIU). It also investigated the relationship between coping, stress, the severity of CIU and psychiatric co-morbidity. Total of 100 CIU patients and 60 allergy patients participated in the study. They completed the General Health Questionnaire, the Social Readjustment Rating Scale, the Perceived Stress Scale, and the Ways of Coping Checklist. Compared with allergy patients, CIU patients had worse co-morbidity and higher levels of life event stress and perceived stress. Emotion-focussed coping was associated with the severity of CIU; perceived stress was associated with co-morbidity. 相似文献

强化治疗是最近几年反复提到的话题。很多临床试验研究各种强化治疗对心血管疾病预后的影响,但结果显示强化治疗并未能带来更多的益处,甚至有害。因此我们必须理性地看待这些所谓的强化治疗。更应该倾向于个体化治疗、综合治疗,包括控制各种危险因素,改善生活的方式。把治疗的眼光放到疾病发生的早期,早治疗,以求更多获益。 相似文献

Previous evidence showed that administration of d-galactose (d-gal) increased ROS production and resulted in impairment of cholinergic system. Troxerutin, a natural bioflavonoid, has been reported to have many benefits and medicinal properties. In this study, we evaluated the protective effect of troxerutin against d-gal-induced impairment of cholinergic system, and explored the potential mechanism of its action. Our results displayed that troxerutin administration significantly improved behavioral performance of d-gal-treated mice in step-through test and morris water maze task. One of the potential mechanisms of this action was decreased AGEs, ROS and protein carbonyl levels in the basal forebrain, hippocampus and front cortex of d-gal-treated mice. Furthermore, our results also showed that troxerutin significantly inhibited cholinesterase (AchE) activity, increased the expression of nicotinic acetylcholine receptor alpha 7 (nAchRα7) and enhanced interactions between nAchRα7 and either postsynaptic density protein 95 (PSD95) or N-methyl-d-aspartate receptors subunit 1 (NMDAR1) in the basal forebrain, hippocampus and front cortex of d-gal-treated mice, which could help restore impairment of brain function. 相似文献
