Burley tobacco is a genotype of chloroplast-deficient mutant with accumulates high levels of tobacco-specific nitrosamines (TSNAs) which would induce malignant tumors in animals. Nitrate is a principle precursor of tobacco-specific nitrosamines. Nitrate content in burley tobacco was significantly higher than that in flue-cured tobacco. The present study investigated differences between the two tobacco types to explore the mechanisms of nitrate accumulation in burley tobacco. transcripts (3079) related to the nitrogen and carbon metabolism were observed. Expression of genes involved in carbon fixation, glucose and starch biosynthesis, nitrate translocation and assimilation were significantly low in burley tobacco than flue-cured tobacco. Being relative to flue-cured tobacco, burley tobacco was significantly lower at total nitrogen and carbohydrate content, nitrate reductase and glutamine synthetase activities, chlorophyll content and photosynthetic rate (Pn), but higher nitrate content. Burley tobacco required six-fold more nitrogen fertilizers than flue-cured tobacco, but both tobaccos had a similar leaf biomass. Reduced chlorophyll content and photosynthetic rate (Pn) might result in low carbohydrate formation, and low capacity of nitrogen assimilation and translocation might lead to nitrate accumulation in burley tobacco.

ObjectivesCultivation of compassion is a useful way to treat mental problems, but some individuals show resistance. Fears of compassion can be an obstacle for clinicians when providing psychotherapy, and for clients when engaging in interpersonal relationships. Despite its importance, a Japanese version of fears of compassion scales (for others, from others, and for self) has not yet been developed. This study developed a Japanese version of the Fears of Compassion Scales and tested its reliability and validity.DesignThis study used a cross-sectional design, and a self-report procedure for collecting data.MethodsA total of 485 students (121 males and 364 females) answered self-report questionnaires, including the draft Fears of Compassion Scales—Japanese version.ResultsThere were distinctive factor structures for fear of compassion from others, and for self. The fear of compassion from others scale consisted of concern about compassion from others and avoidance of compassion from others. All scales had good internal consistency, test-retest reliability, face validity, and construct validity. Discrimination and difficulty were also calculated.ConclusionsThese results indicate that the Fears of Compassion Scales—Japanese version is a well-constructed and useful measure to assess fears of compassion and the existence of cultural differences in fears of compassion.

The last few years have seen increasing research on self-report measures of compassion. The Compassionate Engagement and Action Scale (CEAS) is rooted in an evolutionary approach to compassion, which focuses on the competencies of compassion those are engagement with distress or suffering, and taking action to alleviate and prevent it. This study sought to validate the CEAS in a Japanese population using a cross-sectional design. A total of 279 students (82 males, 191 females, 6 unknown) answered self-report questionnaires, including the Japanese version of CEAS. We found single-factor structures for compassion for others scales, compassion from others scales, and compassion for self scales. All scales were found to have acceptable internal consistency, test-retest reliability, content validity, and construct validity. Even though some limitations, these results indicate that the Japanese version of CEAS is an adequately constructed and useful measure to assess compassionate engagement and action toward others, from others, and for the self with Japanese population.
