Experimental autoimmune uveitis (EAU), an animal model of human uveitis, is characterized by infiltration of autoimmune T cells in the uvea as well as in the retina of susceptible animals. EAU is induced by the immunization of uveitogenic antigens, including either retinal soluble-antigen or interphotoreceptor retinoid-binding proteins, in Lewis rats. The pathogenesis of EAU in rats involves the proliferation of autoimmune T cells in peripheral lymphoid tissues and breakdown of the blood-retinal barrier, primarily in the uvea and retina, finally inducing visual dysfunction. In this review, we describe recent EAU studies to facilitate the design of a therapeutic strategy through the interruption of uveitogenic factors during the course of EAU, which will be helpful for controlling human uveitis.

In this review, we provide information about the etiology, risk factors, and clinical presentations of maltreatment to help clinicians better understand child abuse and neglect. Child maltreatment is a major global health challenge that can result in severe consequences. Abused and neglected children are likely to develop psychiatric disorders, such as major depressive disorder, anxiety disorder, and posttraumatic stress disorder. Understanding child maltreatment is expected to prevent and reduce victimization in children, adolescents, and their families.

Experimental autoimmune uveitis (EAU) is an animal model of human autoimmune uveitis that is characterized by the infiltration of autoimmune T cells with concurrent increases in pro-inflammatory cytokines and reactive oxygen species. This study aimed to assess whether betaine regulates the progression of EAU in Lewis rats. EAU was induced via immunization with the interphotoreceptor retinoid-binding protein (IRBP) and oral administration of either a vehicle or betaine (100 mg/kg) for 9 consecutive days. Spleens, blood, and retinas were sampled from the experimental rats at the time of sacrifice and used for the T cell proliferation assay, serological analysis, real-time polymerase chain reaction, and immunohistochemistry. The T cell proliferation assay revealed that betaine had little effect on the proliferation of splenic T cells against the IRBP antigen in an in vitro assay on day 9 post-immunization. The serological analysis showed that the level of serum superoxide dismutase increased in the betainetreated group compared with that in the vehicle-treated group. The anti-inflammatory effect of betaine was confirmed by the downregulation of pro-inflammation-related molecules, including vascular cell adhesion molecule 1 and interleukin-1β in the retinas of rats with EAU. The histopathological findings agreed with those of ionized calcium-binding adaptor molecule 1 immunohistochemistry, further verifying that inflammation in the retina and ciliary bodies was significantly suppressed in the betaine-treated group compared with the vehicle-treated group. Results of the present study suggest that betaine is involved in mitigating EAU through anti-oxidation and anti-inflammatory activities.

Objectives: This study was conducted to investigate the reliability and validity of the Korean version of the DSM-5 Level 2 Cross-Cutting Symptom Measure–inattention [Swanson, Nolan and Pelham, version IV (SNAP-IV)] and anger [Patient-Reported Outcome Measurement Information System (PROMIS) Anger] for parents and guardians of children aged 6–17 years. Methods: We included 104 children and adolescents diagnosed with attention-deficit/hyperactivity disorder (ADHD), ADHD with anxiety and depression, depressive disorder, anxiety disorder, and tic disorder with somatic symptoms (ADHD=41, depression=9, anxiety=14, ADHD+anxious depression=11, tic+somatic symptoms=29). Their ages ranged from 8 years to 15 years. The participants’ mothers completed the SNAP-IV, PROMIS Anger scale, Korean version of the IOWA Conners Rating Scale (K-IOWA), and Korean ADHD Rating Scale (K-ARS) so that the reliability and validity of the SNAP-IV and PROMIS Anger scales, which are DSM-5 scales for assessing inattention and anger of children and adolescents, could be examined. Results: The reliability coefficient of SNAP-IV (Cronbach’s α) was 0.94. The correlation coefficients between SNAP-IV, K-IOWA inattention, and K-ARS inattention scores ranged from 0.73 to 0.86. The mean SNAP-IV scores of the ADHD and the ADHD+anxious depression groups were significantly higher than those of the anxiety and the tic+somatic symptoms groups. The reliability coefficient of the PROMIS Anger was 0.91. The correlation coefficient between PROMIS Anger and K-IOWA oppositional/defiant scores was 0.75.The PROMIS Anger mean score of the ADHD+anxious depression group tended to be higher than that of the other groups. Conclusion These results suggest that the Korean version of the DSM-5 Level 2 Cross-Cutting Symptom Measure–inattention and anger for parent and guardian of child age 6–17 might be a reliable and valid test and may be useful for screening children and adolescents with ADHD.

BACKGROUND: Colorectal cancer (CRC) is one of the most common malignancies worldwide. Approximately 10%–15% of the CRC cases have defective DNA mismatch repair (MMR) genes. Although the high level of microsatellite instability status is a predictor of favorable outcome in primary CRC, little is known about its frequency and importance in secondary CRC. Immunohistochemical staining (IHC) for MMR proteins (e.g., MLH1, MSH2, MSH6, and PMS2) has emerged as a useful technique to complement polymerase chain reaction (PCR) analyses. METHODS: In this study, comparison between the MMR system of primary CRCs and paired liver and lung metastatic lesions was done using IHC and the correlation with clinical outcomes was also examined. RESULTS: Based on IHC, 7/61 primary tumors (11.4%) showed deficient MMR systems, while 13/61 secondary tumors (21.3%) showed deficiencies. In total, 44 cases showed proficient expression in both the primary and metastatic lesions. Three cases showed deficiencies in both the primary and paired metastatic lesions. In 10 cases, proficient expression was found only in the primary lesions, and not in the corresponding metastatic lesions. In four cases, proficient expression was detected in the secondary tumor, but not in the primary tumor. CONCLUSIONS: Although each IHC result and the likely defective genes were not exactly matched between the primary and the metastatic tumors, identical results for primary and metastatic lesions were obtained in 77% of the cases (47/61). These data are in agreement with the previous microsatellite detection studies that used PCR and IHC.

PURPOSE: The purpose of this study was to determine the influence of sustainability management in institutional foodservice on store image and behavioral intention (revisit intention, word of mouth, willingness to pay a premium). METHODS: Based on a total of 371 samples obtained from the empirical research, this study reviewed the reliability and fitness of the model. RESULTS: According to results of exploratory factor analysis, sustainability management derived three factors, economic value, socially responsible, and environmentally sound. The structural equation modeling showed that social responsibility in sustainability management had a significant positive effect on store image and behavioral intention. In addition, customer's perceived store image in foodservice had a significant positive effect on behavioral intention. The relationship between sustainability management and behavioral intention was found to be a partially significant effect. CONCLUSION: The results of this study revealed the importance of sustainability management of foodservice to improve store image and behavioral intention.

Food is an essential component of good health and a high quality of life. This is especially true for the elderly, where health and quality of life can vary due to eating issues. This study attempts to measure the satisfaction with food-related life in the elderly of South Korea, while examining differences in social support, depression, isolation, and life satisfaction based on the level of satisfaction with food-related life. Data collection was conducted using one-on-one surveys from December 2011 to January 2012. A total of 390 elderly (aged 65 and over) who live in Korea participated in this study. The results showed that the satisfaction with food-related life was high (3.52 out of 5). The elderly who had company during a meal or a meal preparer showed a higher satisfaction with their food-related life. Social support was high (5.32 out of 7) and the feelings of isolation were low (3.85 out of 5). The average satisfaction with life was 4.42 out of 7, indicating a fair satisfaction with life, while the average depression score was relatively low (8.77 out of 26). In general, the elderly with a higher satisfaction with food-related life had a higher social support and overall satisfaction with their life. On the other hand, the elderly with a lower satisfaction with food-related life generally reported higher levels of depression and isolation. A positive correlation was observed between satisfaction with food-related life, social support, and satisfaction of life, while a negative correlation was found between satisfaction with food-related life, isolation, and depression. The results of this study indicate that managing the satisfaction with food-related life is an important component of mental health in the elderly.
