    Nuclear transfer stem cells (NTSC) holds considerable promise in the field of regenerative medicine and cellbased drug discovery. In this study, a total of 29 oocytes were obtained from three young (20–24 y) reproductive egg donors who had been successful in previous cycles. These oocytes, deemed by intended parents to be in excess of their reproductive needs, were donated for research without financial compensation by both the egg donor and intended parents after receiving informed consent. All intended parents successfully achieved ongoing pregnancies with the oocytes retained for reproductive purposes. Mature oocytes, obtained within 2 h following transvaginal aspiration, were enucleated using one of two methods, extrusion or aspiration, after 45 min incubation in Cytochalasin B. Rates of oocyte lysis or degeneration did not differ between the two methods. Somatic cell nuclear transfer (SCNT) embryos were constructed using two established adult male fibroblast lines of normal karyotype. High rates of pronuclear formation (66%), early cleavage (47%) and blastocyst (23%) development were observed following incubation in standard IVF culture media. One cloned blastocyst was confirmed by DNA and mtDNA fingerprinting analyses and DNA fingerprinting of two other cloned blastocysts indicated they were also generated by SCNT. Blastocysts were also obtained from a limited number of parthenogenetically activated oocytes. This study demonstrates, for the first time, that SCNT can produce human blastocyst stage embryos using nuclei from a differentiated adult somatic cell, and provides new information on methods that may be needed for a higher level of efficiency for human therapeutic cloning.

    Objective

    Obesity is an increasingly prevalent public health problem worldwide, and is associated with a higher risk of developing various noncommunicable diseases. To further examine the association between personality and overweight, obesity, or underweight, we conducted a cross-sectional analysis in Japan. We hypothesized that extraversion and psychoticism would have a positive association with overweight, and that neuroticism and lie would have an inverse association with overweight, whereas the association between personality and underweight would be the reverse image of overweight.

    Methods

    In 1990, 30,722 subjects (40–64 years of age) completed a self-administered questionnaire including body weight and height and the Japanese version of the Eysenck Personality Questionnaire-Revised Short Form. Multivariate logistic regression analysis was used to calculate odds ratios for overweight [body mass index (BMI)≥25.0 kg/m2] or underweight (BMI<18.5) relative to each category on the personality subscale. Results

    In men and women, extraversion and psychoticism had positive associations with overweight, whereas neuroticism had an inverse association. Lie had an inverse association with overweight in men. In men and women, only extraversion had an inverse association with underweight and neuroticism had a positive association with underweight.

    Conclusion

    Our findings indicate that personality is associated with both overweight and underweight. These results may provide clues to devising more effective measures for preventing overweight, obesity, or underweight or for weight control intervention.
