1.The association between PGC-1a and Alzheimer's disease.
Anatomy & Cell Biology 2016;49(1):1-6
Alzheimer's disease (AD) is a neurodegenerative disorder and its reported pathophysiological features in the brain include the deposition of amyloid beta peptide, chronic inflammation, and cognitive impairment. The incidence of AD is increasing worldwide and researchers have studied various aspects of AD pathophysiology in order to improve our understanding of the disease. Thus far, the onset mechanisms and means of preventing AD are completely unknown. Peroxisome proliferator-activated receptor-γ coactivator (PGC-1α) is a protein related to various cellular mechanisms that lead to the alteration of downstream gene regulation. It has been reported that PGC-1α could protect cells against oxidative stress and reduce mitochondrial dysfunction. Moreover, it has been demonstrated to have a regulatory role in inflammatory signaling and insulin sensitivity related to cognitive function. Here, we present further evidence of the involvement of PGC-1α in AD pathogenesis. Clarifying the relationship between PGC-1α and AD pathology might highlight PGC-1α as a possible target for therapeutic intervention in AD.

2.Drug-nutrient Interactions in Elderly Patients.
Journal of Clinical Nutrition 2014;6(1):11-18
Physiological changes associated with aging affect the absorption, distribution, metabolism, and excretion of drugs and thus therapeutic outcomes. These changes may be further amplified by interactions with nutrients. The purpose of this review was to summarize drug-nutrient interactions found in elderly patients. Mechanisms of the interactions can be categorized as ex vivo bio-inactivations, interactions in absorption and elimination phases, and physiological interactions. The goal of enteral nutrition (EN) is to maximize the therapeutic response of medication without adversely affecting EN tolerance. Therefore, to ensure safety, consistent monitoring is necessary for enteral feeding of patients receiving medication via an enteral tube. Elderly patients receiving parenteral nutrition (PN) are often treated concomitantly with medication via the parenteral route. The stability and compatibility of PN formulations infused with other additives, including medication, may be influenced. Limitation of the number of prescriptions to essential medications only during the minimum period along with periodic re-evaluations of the treatment are thus necessary to minimize undesirable drug-nutrient interactions in elderly patients.

3.Adiponectin as a new paradigm for approaching Alzheimer's disease.
Anatomy & Cell Biology 2013;46(4):229-234
Adiponectin is an adipocytokine released by the adipose tissue and has multiple roles in the immune system and in the metabolic syndromes such as cardiovascular disease, Type 2 diabetes, obesity and also in the neurodegenerative disorders including Alzheimer's disease. Adiponectin regulates the sensitivity of insulin, fatty acid catabolism, glucose homeostasis and anti-inflammatory system through various mechanisms. Previous studies demonstrated that adiponectin modulates memory and cognitive impairment and contributes to the deregulated glucose metabolism and mitochondrial dysfunction observed in Alzheimer's disease. Here, we aim to summarize recent studies that suggest the potential correlation between adiponectin and Alzheimer's disease.

PURPOSE: This study was conducted to investigate the related factors of insight, self-esteem, and coping skills and the relationships among them in patients with alcohol addiction. METHODS: The participants enrolled in this study were 106 patients from two alcohol treatment hospitals in Gyeonggi Province. Data were collected from May, 12 to 20, 2010 using self-report questionnaires. The instruments were the Hanil Alcohol Insight Scale, Rosenberg Self-esteem Scale, and the Ways of Coping Checklist. Data were analyzed using the SPSS-Win 12.0 program. RESULTS: Among the participants, 24.5% had poor insight, 45.3% fair insight, and 30.2% good insight. Insights of participants who had experienced withdrawal symptoms (t=-3.79, p<.001) and of those not living with family (t=-2.07, p=.041) were higher than those who had not experienced the symptoms and who were not living with family. Self-esteem of participants living with family (F=3.60, p<.001) and of those with better academic backgrounds (F=3.39, p=.021) were higher than those of the other groups. Also, self-esteem showed a positive relation with active coping (r=.34, p<.001). CONCLUSION: The results of the present study suggest that mental health practitioners need to focus on insight and self-esteem enhancement, coping skill development when treating patients with alcohol addiction.

5.Tic & Tourette Syndrome and Motor Disorders.
Hanyang Medical Reviews 2016;36(1):46-54
Motor disorders in childhood include tic disorder, developmental coordination disorder, and stereotypic movement disorder. A tic is a sudden, rapid, repetitive and nonrhythmic movement (motor tics) or phonic production (phonic or vocal tics) that can occur at any part of the body. Developmental coordination disorder (DCD) is characterized by marked impairment in the acquisition and performance of motor skills. Stereotypic movement disorder is a common childhood disorder which repetitive, hard to control, aimless motor activity interrupts everyday life or causes self-infliction of a child. Despite increased attention and the growing scientific knowledge about motor disorders, there are limitations in our understanding and knowledge about the pathogenesis and the management of the disorders. Motor disorders can itself be the primary diagnosis, or can be secondarily diagnosed caused by other disorders, and accompany many neuropsychiatric disorders such as autism and attention deficit hyperactivity disorder (ADHD), which in turn impairs proper learning and socializing of the children with motor disorders. Therefore comprehensive medical history taking, continuous observation of the changes in symptoms, and systematic assessment considering the child's developmental stage and current adaptive capacity are needed. Behavioral therapy and pharmacological therapy are the two most often mentioned treatments of motor disorders.

Alzheimer's disease (AD) is characterized by the accumulation of amyloid beta (Aβ) and the hyperphosphorylation of tau protein in the brain, leading to the increase in inflammation and neuronal loss. Recently, evidences to support the association between type 2 diabetes mellitus (T2DM) and AD have markedly increased by clinical researches and experimental studies. Reduced insulin action and impaired glucose metabolism in the brain leads to diabetes induced AD. Androgen, a male sex hormone, was known to regulate inflammatory response, Aβ deposition in AD, insulin signaling, and synaptic plasticity in brain. Clinical studies demonstrated that androgen deficiency results in the increased risk of AD and its severe progression in male subjects. We reviewed the significant evidences to support that low testosterone levels are linked to diabetes-induced AD based on previous studies. Thus, we highlight the therapeutic potential of androgen in diabetes induced AD.

7.The Effect of Health Promoting Behavior on Stress among Resort Workers
Korean Journal of Occupational Health Nursing 2018;27(2):99-108
PURPOSE:
This study aimed to identify the factors affecting stress among resort workers.
METHODS:
The subjects of the study were 199 resort workers in a province of Korea. Data were collected using self-administered questionnaires that were completed between November 16, 2017 and January 19, 2018. The questionnaire consisted of stress and health promoting behavior and its sub-areas such as health responsibilities, physical activity, nutrition, spiritual growth, interpersonal relations, and stress management. Using the SPSS 23.0 program, descriptive statistics, t-test, ANOVA, correlation analysis, and multiple regression analysis were conducted.
RESULTS:
The mean score of the stress levels of resort workers was 2.3±0.98 out of a maximum score of 5. A multiple regression analysis revealed that gender, spiritual growth, and stress management were statistically significant factors in the model (p < .001), with an explanatory power of 35%.
CONCLUSION
Stress levels were considerably high in resort workers. This study suggests that nursing interventions are needed to reduce stress levels and enhance health promoting behavior, especially spiritual growth and stress management, at both an individual and organizational level.
8.Intermittent Fasting: a Promising Approach for Preventing Vascular Dementia
Journal of Lipid and Atherosclerosis 2019;8(1):1-7
Vascular dementia is the most common neuropsychiatric syndrome and is characterized by synaptic dysfunction, neuroinflammation, and cognitive dysfunction. Vascular dementia is associated with various environmental, genetic, and lifestyle risk factors. Recent research has focused on the association between vascular dementia and dietary patterns, suggesting that dietary regulation leads to better control of energy metabolism, improvements in brain insulin resistance, and the suppression of neuroinflammation. Intermittent fasting is a calorie-restriction method known to be more effective in promoting fat loss and regulating the impairment of glucose metabolism as compared with other dietary restriction regimens. Herein, the authors review the effects of intermittent fasting with regard to vascular dementia based on recent evidence and propose that intermittent fasting could be a therapeutic approach for ameliorating vascular dementia pathology and preventing its onset.

9.Discovery and Functional Prediction of Long Non-Coding RNAs Common to Ischemic Stroke and Myocardial Infarction
Journal of Lipid and Atherosclerosis 2020;9(3):449-459
Objective:
Ischemic stroke and myocardial infarction are 2 of the leading causes of mortality. Both conditions are caused by arterial occlusion, resulting in ischemic necrosis of the cells in the cortex and heart. Long non-coding RNAs (lncRNAs) are a group of non-coding RNAs longer than 200 nucleotides without protein-coding potential. Thousands of lncRNAs have been identified but their involvement in ischemic stroke and myocardial infarction has not been studied extensively. Therefore, this study aimed to identify the role of lncRNAs, particularly those that are commonly altered in these two ischemic injuries.
Methods:
We combined diverse RNA sequencing data obtained from public databases and performed extensive bioinformatics analyses to determine reliable lncRNAs commonly identified from these datasets. Using sequence analysis, we also detected the lncRNAs that may act as microRNA (miRNA) regulators.
Results:
We found several altered lncRNAs that were common in ischemic stroke and myocardial infarction models. Some of these lncRNAs, including zinc finger NFX1-type containing 1 antisense RNA 1 and small nucleolar RNA host gene 1, were previously reported to be involved in the pathogenesis of each of these models. Interestingly, several lncRNAs had binding sites for miRNAs that were previously reported to be involved in the hypoxic response, suggesting the possible role of these lncRNAs as regulators in ischemic responses.
Conclusion
The lncRNAs identified in this study will be useful in determining the regulatory networks in ischemic stroke and myocardial infarction and in identifying potential specific markers for each of these ischemic diseases.
