The partition functions of c < 1 minimal unitary conformal theories are completely classified. It is proven that the list given by Cappelli, Itzykson and Zuber exhausts the set of physically acceptable solutions.

ObjectiveGrowing qualitative evidence reveals that many patients with chronic illnesses struggle to rebuild a positive self-image after diagnosis while attempting to find a balance between their current physical status and their ongoing social duties. One factor destabilizing patients’ identities is self-stigma, which seems to affect their behavioral goals through decreased self-efficacy. We hypothesized that self-stigma would be an independent factor, distinct from self-efficacy, for developing self-care behaviors in patients with type 2 diabetes.MethodsWe used a consecutive sample of 209 outpatients with type 2 diabetes treated by endocrinologists at two university hospitals, one general hospital and one clinic. We performed multiple linear regression analyses to test the relationship between the patients’ activation levels for self-care behaviors (dependent variable) and self-stigma, self-efficacy, and depression symptoms (independent variables), adjusting for covariates involving sociodemographic and clinical characteristics.ResultsIn a multiple linear regression model adjusted for prior covariates, there was significant association between self-stigma and activation levels for self-care behaviors in patients with type 2 diabetes (adjusted R2=0.26, F (12,196)=7.20, p<0.001). The standardized partial regression coefficient of self-stigma was −0.23 (p=0.001), whereas that of self-efficacy was 0.19 (p=0.007).ConclusionsSelf-stigma is a negative independent factor, separate from self-efficacy, affecting the self-care behaviors of patients with type 2 diabetes. Self-stigma also has, at least, a similar impact on self-care behaviors to that of self-efficacy. To optimize treatment outcomes, patients’ self-stigma should be minimized, whereas their self-efficacy should be enhanced.

We consider actions for N D-branes at points in a general Kähler manifold, which satisfy the axioms of D-geometry, and could be used as starting points for defining Matrix theory in curved space.We show that the axioms cannot be satisfied unless the metric is Ricci flat, and argue that such actions do exist when the metric is Ricci flat. This may provide an argument for Ricci flatness in Matrix theory.

BackgroundSelf-stigma has been highlighted and researched in relation to patients with chronic illnesses, as it may have a negative impact on their treatment adherence. However, self-stigma has not yet been investigated in patients with type 2 diabetes. In order to evaluate the extent to which patients with type 2 diabetes experience self-stigma, which may result in their poor self-care management, there is a need for a specific tool to measure self-stigma in patients with type 2 diabetes. This study assessed the psychometric properties of a Japanese version of the Self-Stigma Scale (SSS-J) in patients with type 2 diabetes.MethodsThe reliability and validity of the SSS-J were evaluated using a consecutive sample of 210 outpatients with type 2 diabetes from university hospitals and from hospitals or clinics specializing in diabetes treatment. Confirmatory factor analysis was conducted to assess the factors theorized by the original Self-Stigma Scale. Cronbach’s alpha for internal reliability and Pearson’s correlations for construct validity were used for evaluation of psychometric properties. Pearson’s correlations for test-retest reliability of the SSS-J were also performed.ResultsConfirmatory factor analysis verified the three-factor structure of the SSS-J, consisting of cognitive, affective, and behavioral subscales. The model fit indices were as follows: the goodness-of-fit index was 0.78, the adjusted goodness-of-fit index was 0.70, the comparative fit index was 0.88, and the root mean square error of approximation was 0.07. Cronbach’s alpha of the SSS-J was 0.96 (cognitive: alpha = 0.92; affective: alpha = 0.93; behavioral: alpha = 0.83). The SSS-J was associated with self-esteem (r = −0.43, p < 0.01), self-efficacy (r = −0.38, p < 0.01), and depressive symptoms (r = 0.39, p < 0.01). The 2-week test-retest reliability demonstrated satisfactory stability (r = 0.76, p < 0.01).ConclusionsThe SSS-J is reliable and valid for assessment of the extent of self-stigma in Japanese patients with type 2 diabetes.

Soy protein β-conglycinin has serum lipid-lowering and anti-obesity effects. We showed that single ingestion of β-conglycinin after fasting alters gene expression in mouse liver. A sharp increase in fibroblast growth factor 21 (FGF21) gene expression, which is depressed by normal feeding, resulted in increased postprandial circulating FGF21 levels along with a significant decrease in adipose tissue weights. Most increases in gene expressions, including FGF21, were targets for the activating transcription factor 4 (ATF4), but not for peroxisome proliferator-activated receptor α. Overexpression of a dominant-negative form of ATF4 significantly reduced β-conglycinin-induced increases in hepatic FGF21 gene expression. In FGF21-deficient mice, β-conglycinin effects were partially abolished. Methionine supplementation to the diet or primary hepatocyte culture medium demonstrated its importance for activating liver or hepatocyte ATF4-FGF21 signaling. Thus, dietary β-conglycinin intake can impact hepatic and systemic metabolism by increasing the postprandial circulating FGF21 levels.

ObjectivesSelf-stigma is associated with lower patient activation levels for self-care in persons with type 2 diabetes mellitus (T2DM). However, the causal pathway linking self-stigma with patient activation for self-care has not been shown. In order to determine how self-stigma affects patient activation for self-care, we tested a two-path hypothetical model both directly and as mediated by self-esteem and self-efficacy.DesignA cross-sectional study.SettingTwo university hospitals, one general hospital and one clinic in Japan.ParticipantsT2DM outpatients receiving treatment (n=209) completed a self-administered questionnaire comprising the Self-Stigma Scale, Patient Activation Measure, Rosenberg Self-Esteem Scale, General Self-Efficacy Scale, Patient Health Questionnaire, haemoglobin A1c test, age, sex and body mass index.Primary and secondary outcome measuresSelf-stigma levels were measured by using the Self-Stigma Scale. Patient activation levels were measured by the Patient Activation Measure.ResultsPath analysis showed a strong relationship between self-stigma and patient activation (χ2=27.55, p=0.120; goodness-of-fit index=0.97; adjusted goodness-of-fit index=0.94; comparative fit index=0.98; root mean square error of approximation=0.04). Self-stigma had a direct effect on patient activation (β=−0.20; p=0.002). Indirectly, self-stigma affected patient activation along two paths (β=0.31; p<0.001) by reducing self-esteem (β=−0.22; p<0.001) and self-efficacy (β=−0.36; p<0.001).ConclusionsDue to the cross-sectional design of the study, longitudinal changes between all the variables cannot be established. However, the findings indicate that self-stigma affected patient activation for self-care, both directly and as mediated by self-esteem and self-efficacy. Interventions that increase self-esteem and self-efficacy may decrease self-stigma in patients with T2DM, thus increasing patient activation for self-care.

ObjectivesThe aim of this study was to test the psychological and behavioural patterns of stigma (self-esteem and social participation) and their relationship to self-stigma, patient activation for engaging in self-care and glycaemic control among patients with type 2 diabetes mellitus (T2DM).DesignA cross-sectional study.Setting2 tertiary-level hospitals and 2 secondary-level hospitals in Japan.ParticipantsA consecutive sample of 209 outpatients with T2DM. Inclusion criteria were as follows: presence of T2DM, age 20–74 years, no diagnosis of dementia and/or psychosis, and no need for urgent medical procedures.Outcome measuresStudy measures included a self-administered questionnaire to assess the Rosenberg Self-Esteem Scale (SES), the 3 subscales of 36-question Short Form Health Survey (SF-36; Social Function, Role Physical, Role Emotional), Self-Stigma Scale and Patient Activation Measure (PAM-13). Glycated haemoglobin was obtained from same day blood work. In our previous qualitative study, we found that psychological and behavioural patterns of stigma varied according to patients' levels of illness-related self-esteem as well as attitudes towards social participation. For quantitative consistency, we used the SES scale to measure self-esteem and the SF-36 subscales to measure social participation. We then divided participants into 4 groups by exhibited psychological and behavioural patterns: group A (high SES/high SF-36), group B (high SES/low SF-36), group C (low SES/high SF-36) and group D (low SES/low SF-36).ResultsUsing analysis of covariance after controlling for age and sex, there was a significant difference in self-stigma levels between the four groups (F[3203]=15.70, p<0.001). We observed the highest mean self-stigma levels in group D. Group D also had significantly lower PAM-13 scores than those of groups A (p<0.001) and B (p=0.02).ConclusionsThe psychological and behavioural pattern of group D was found to be associated with higher levels of self-stigma and poorer patient activation for self-care.
