Purpose: To investigate the cerebral blood flow (CBF) alterations associated with poor sleep quality and memory performance in firefighters. Participants and methods: Thirty-seven firefighters (the FF group) and 37 non-firefighter controls (the control group) with sleep complaints were enrolled in this study. We performed brain arterial spin lab...
Article
Background Bright light exposure is a safe non-pharmacological intervention for sleep disturbances. However, the functional brain correlates underlying the effects of bright light exposure need to be further clarified. As alterations in the salience network were reported in individuals with sleep disturbances, we have investigated whether bright li...

The epigenetic regulation of microRNA (miRNA) expression related to the FK506-binding protein 5 (FKBP5) gene may contribute to the risk of stress-related disorders such as posttraumatic stress disorder (PTSD). Here, we identified candidate miRNAs derived from FKBP5 knockout mice as a potential diagnostic biomarker of PTSD. Using a translational app...
Article
Background Alterations in the levels of gamma-aminobutyric acid (GABA) and glutamate+glutamine (Glx), which are major inhibitory and excitatory neurotransmitters, respectively, are frequently associated with insomnia. Previous reports also suggested the involvement of the anterior cingulate cortex (ACC) and medial prefrontal cortex (mPFC) in insomn...
Article
Cognitive dysfunction has long been recognized as a frequently observed symptom in individuals with repetitive mild traumatic brain injury (rmTBI) such as professional boxers. The exact neurobiological mechanisms underlying this cognitive deficit have not yet been identified, but it is agreed upon that the prefrontal cortex (PFC) is one of the most...

Early intervention using dietary supplements may be effective in alleviating cognitive impairment among individuals with mild cognitive impairment (MCI). This study investigated the efficacy and safety of Lactobacillus plantarum C29-fermented soybean (DW2009) as a nutritional supplement for cognitive enhancement. One hundred individuals with MCI we...

Background Firefighters are routinely exposed to various traumatic events and often experience a range of trauma-related symptoms. Although these repeated traumatic exposures rarely progress to the development of post-traumatic stress disorder, firefighters are still considered to be a vulnerable population with regard to trauma. Aims To investiga...

The caudate nucleus has shown a high relevance with substance craving and addiction in the pathophysiology of alcohol dependence. In this study, caudate volumetric deficits in patients with alcohol dependence and their associations with carbohydrate-deficient transferrin (CDT), a biomarker of chronic alcohol consumption, were evaluated in 21 patien...
Article
Although most teachers realize the seriousness of bullying and try to intervene, some take a passive stance, while others take active action. The present study examined individual and environmental factors that make teachers either passive or active interveners. Self‐reported questionnaires were collected from 200 middle school teachers in South Ko...
Article
Insufficient sleep, insomnia, and sleep-related problems are important health issues, as their overall prevalence accounts for about 30% of the general population. The aim of this study was to systematically review previous studies investigating the effects of orally administered single plant-derived extracts on sleep-related outcomes in humans. Da...

The efficacy and safety of Tremella fuciformis (TF) as a nutritional supplement were assessed in individuals with subjective cognitive impairment (SCI). Seventy-five individuals with SCI were enrolled in an 8-week, randomized, double-blind, placebo-controlled trial of TF (600 mg/day, n = 30 or 1200 mg/day, n = 30) or placebo (n = 15). The primary o...

Repeated exposure to traumatic experiences may put professional firefighters at increased risk of developing posttraumatic stress disorder (PTSD). To date, however, the rate of PTSD symptoms, unmet need for mental health treatment, and barriers to treatment have only been investigated in subsamples rather than the total population of firefighters....

Aims/hypothesis: Overweight and obesity may significantly worsen glycaemic and metabolic control in type 2 diabetes. However, little is known about the effects of overweight and obesity on the brains of people with type 2 diabetes. Here, we investigate whether the presence of overweight or obesity influences the brain and cognitive functions durin...
Article
The purpose of this randomised crossover study is to validate the Korean version of the Affective Go/No-go (AGN) test. The Korean words for the AGN test were selected after careful evaluation of emotional valences, word length and frequency. Fifteen Korean advanced learners of English were administered both Korean and English versions, yielding 30...
Article
Problematic alcohol consumption is prevalent among first responders because alcohol is commonly used to cope with occupational stress and frequent exposure to traumatic incidents, making them an at-risk population for alcohol use disorders (AUD). This study investigated the psychometric properties of the Korean version of the Alcohol Use Disorders...

Background and Purpose Although subjective cognitive impairment (SCI) is often accompanied by Parkinson's disease (PD) and may predict the development of mild cognitive impairment or dementia, longitudinal brain perfusion changes in PD patients with SCI remain to be elucidated. The current prospective study examined cerebral perfusion changes in PD...
Conference Paper
The whole-school approach to reducing bullying is in the spotlight. Although studies have addressed contextual factors such as classroom norms and school climate, specific characteristic of teachers has not been investigated yet. Therefore, this study intends to explore individual and environmental factors that promote teachers’ interventions in bu...
