We investigated the potential effects of Costaria costata (CC) on atopic dermatitis (AD) development in chloro-2,4-dinitrobenzene (DNCB)-treated NC/Nga mice. CC is a brown alga distributed across the seas of Korea, China, and Japan. A total of 40 mice were randomly assigned to 5 groups with 8 mice per group: untreated Balb/c mice, AD control (0.1% w/v DNCB-treated NC/Nga mice), positive control (i.e., DNCB-treated NC/Nga mice fed a dietary supplement of 66.6 mg/kg of body weight [b.w.] of CJLP133), DNCB-treated NC/Nga mice fed a dietary supplement of 100 mg/kg b.w. of CCE10 (CCE10 100), and DNCB-treated mice fed a dietary supplement of 300 mg/kg b.w. of CCE10 (CCE10 300) groups. The CCE10 100 and CCE10 300 treatment groups suppressed AD development including clinical and histopathological changes and a reduction in skin hydration induced by DNCB. In addition, Th2 cytokine production in primary splenocytes, serum IgE and histamine production, and mast cell infiltration into the skin were suppressed in the CCE10 300 mice compared to the CCE10 100 mice. Our finding demonstrated an inhibitory effect of CCE10 in AD development by means of improving the Th1/Th2 cytokine balance and anti-inflammatory effect in an in vivo model.

Ophthalmic formulations have classically been administered to eyes through eye drops, which have poor delivery efficiency and require frequent instillation. As a means of overcoming these drawbacks, ocular-drug delivery via therapeutic contact lenses has caused great interest. A simple way to prepare therapeutic contact lenses is to immerse lenses in concentrated drug solution. However, not all ocular drugs can be efficiently loaded into contact lenses by a simple soaking. In particular, our previous study showed that two antibacterial ocular drugs, ofloxacin (OFX) and neomycin (NEO), were poorly loaded to poly(2-hydroxyethyl methacrylate) (pHEMA)-based contact lenses. Herein, we investigated whether alteration of lens composition using several negatively charged comonomers can enhance loading of ocular drugs with poor loadability (OFX and NEO). As comonomers, methacrylic acid (MAA), acrylic acid (AA), and 4-methyl-4-pentenoic acid (MPA) were used, generating p(HEMA-co-MAA), p(HEMA-co-AA), and p(HEMA-co-MPA) hydrogel-based contact lenses, respectively. Contact lenses containing comonomers exhibited an increase in loading of OFX and NEO. In particular, compared with pHEMA contact lenses, contact lenses containing 2.5 mol% AA exhibited enhanced loading of OFX and NEO, 18 and 53 times, respectively. Charge interactions between comonomers and the drug were considered primary factors in the substantial increase in drug loading.

In this study, functional particles such as piezoelectric (PZT) ceramic and shape memory alloy (SMA) particles have been incorporated in composite laminates to accelerate the loss of vibration energy. PZT ceramic particles and SMA particles are mixed with epoxy resin and rolled into a film shape before they are interleaved between prepreg plies for better distribution of the particles. Loss factor (tan δ) was measured with various particle loadings to verify the effectiveness of interleaving in the vibration damping of laminate specimens. It was observed that there existed an optimal content for maximizing the damping ability avoiding an aggregation of the particles. In addition, when PZT and SMA particles are applied simultaneously, PZT could enhance the vibration damping capability of SMA because PZT particles could generate thermal energy, and it would accelerate the phase change of the SMA particles. In this research, the effective way for enhancing the particle dispersion was suggested, and the particle loading could be controlled by finding an optimal content. Flexural moduli of the specimens were also measured, and they exhibited no change as the content of the particles increases. Therefore, dispersed particles used in this study increased the vibration damping capacity without reducing the mechanical properties.

The macromolecular composition of phytoplankton communities and the proximate composition of zooplankton communities were measured monthly in the southwestern East/Japan Sea from April to November 2014 in order to identify seasonal changes in, and relationships among, the biochemical compositions in both phytoplankton and zooplankton. The carbohydrate content of phytoplankton was highest in June, whereas the protein content was highest in August and lipids were highest in April. Overall, carbohydrates were dominant (53.2 ± 12.5%) in the macromolecular composition of phytoplankton during the study period. This composition is believed to result from the dominance of diatoms and/or nutrient-depleted conditions. In comparison, the protein level of zooplankton was highest in November, whereas lipids were slightly higher in May than other months. Overall, proteins were the dominant organic compounds (47.9±8.6% DW) in zooplankton communities, whereas lipids were minor components (5.5±0.6% DW). The high protein content of zooplankton might be related to the abundance of copepods, whereas the low lipid content might be due to a relatively high primary production that could provide a sufficient food supply for zooplankton so that they do not require high lipid storage. A significant positive correlation (r=0.971, n=7, p

The minke whale ( Balaenoptera acutorostrata ) is the most common baleen whale among several marine mammal species observed in Korea. Since a high concentrated condition of prey to whales can be obtained by physical structures, the foraging whale distribution can be an indicator of biological hotspot. Our main objective is verifying the coastal upwelling-southwestern East Sea as a productive biological hotspot based on the geographical distribution of minke whales. Among the cetacean research surveys of the National Institute of Fisheries Science since 1999, 9 years data for the minke whales available in the East Sea were used for this study. The regional primary productivity derived from Moderate-Resolution Imaging Spectroradiometer (MODIS) was used for a proxy of biological productivity. Minke whales observed during the sighting surveys were mostly concentrated in May and found mostly (approximately 70%) in the southwestern coastal areas ( −2 y −1 ) estimated in the southwestern coastal region of the East Sea belongs to the highly productive coastal upwelling regions in the world. A change in the main spatial distribution of minke whales was found in recent years, which indicate that the major habitats of mink whales have been shifted into the north of the common coastal upwelling regions. This is consistent with the recently reported unprecedented coastal upwelling in the mid-eastern coast of Korea. Based on high phytoplankton productivity and high distribution of minke whales, the southwestern coastal regions can be considered as one of biological hotspots in the East Sea. These regions are important for ecosystem dynamics and the population biology of top marine predators, especially migratory whales and needed to be carefully managed from a resource management perspective.

This study investigates the role of agility in the relationship between use of management control systems (MCS) and organizational performance by proffering the association of agility, use of MCS, and organizational performance. Using survey data collected from 185 large Korean and Japanese manufacturing companies, we analyze proposing relationships with partial least squares (PLS) structural equation approach. The result shows that diagnostic use of MCS shows no significant relationship with agility, while interactive use of MCS is positively associated with agility. Agility positively affects organizational performance, which implies that characteristics of agility are necessary to overwhelm rivals under rapidly changing environment. This study is one of the first studies that empirically examine the role of agility as an organizational capability in the relationship between MCS and organizational performance with data collected from two different countries.

Adolescence is a unique period in which higher cognition develops to adult-level, while plasticity of neuron and behavior is at one of its peak. Yet, cognitive training studies for adolescents has been sparse and neural correlates of the training effects yet to be established. This study investigated the effects of multicomponent training of cognitive control (MTCC) in order to examine whether the training enhanced adolescents' cognitive control ability and if the effects were generalizable to other cognitive domains. Cognitive control refers to the ability to adjust a series of thoughts and behaviors in correspondence to an internal goal, and involves inhibition, working memory, shifting, and dual tasking as subcomponents. The participants were middle school students (aged 11–14) and randomly assigned to either a training group or an active control group. The training group performed 30 minutes of MTCC per day for six weeks. To identify the training effects, we examined the cognitive performance, regional gray matter, and their relationship. The training group showed modest improvement in a visuospatial fluid intelligence test (Block Design) after MTCC, which was not significant after correcting for multiple comparisons. In addition, the training effect on the gray matter volume (time × group interaction) was observed in the right inferior cortex (rIFC). While the control group showed a typical reduction in the rIFC volume, the training group showed a relative increase in the homologous region. The relative change in rIFC volume was associated with the change in Stroop performance. These results imply that MTCC may affect brain structure relevant to inhibitory control process.

Background The non-saponin fraction of Korean Red Ginseng has been reported to have many biological activities. However, the effect of this fraction on anti-diabetic activity has not been elucidated in detail. In this study, we investigated the effects of KGC05P0, a non-saponin fraction of Korean Red Ginseng, on anti-diabetic activity in vitro and in vivo. Methods We measured the inhibition of commercially obtained α-glucosidase and α-amylase activities in vitro and measured the glucose uptake and transport rate in Caco-2 cells. C57BL/6J mice and C57BLKS/Jdb/db (diabetic) mice were fed diets with or without KGC05P0 for eight weeks. To perform the experiments, the groups were divided as follows: normal control (C57BL/6J mice), db/db control (C57BLKS/Jdb/db mice), positive control (inulin 400 mg/kg b.w.), low (KGC05P0 100 mg/kg b.w.), medium (KGC05P0 200 mg/kg b.w.), and high (KGC05P0 400 mg/kg b.w.). Results KGC05P0 inhibited α-glucosidase and α-amylase activities in vitro, and decreased glucose uptake and transport rate in Caco-2 cells. In addition, KGC05P0 regulated fasting glucose level, glucose tolerance, insulin, HbA1c, carbonyl contents, and proinflammatory cytokines in blood from diabetic mice and significantly reduced urinary glucose excretion levels. Moreover, we found that KGC05P0 regulated glucose production by down-regulation of the PI3K/AKT pathway, which inhibited gluconeogenesis. Conclusion Our study thereby demonstrated that KGC05P0 exerted anti-diabetic effects through inhibition of glucose absorption and the PI3K/AKT pathway in in vitro and in vivo models of diabetes. Our results suggest that KGC05P0 could be developed as a complementary food to help prevent T2DM and its complications.

Supplemental Digital Content is available in the text, The brain has multiple functions, and its structures are very closely related to one another. Thus, the brain areas associated with stress, emotion, and intelligence are closely connected. The purpose of this study was to investigate the multiple associations between stress and emotional intelligence (EI), between EI and intelligence quotient (IQ), between cytokines and stress, and between cytokines and IQ. We measured the stress, EI, cognitive intelligence using IQ, and cytokine levels of 70 healthy subjects. We also analyzed the association of cytokines with IQ according to hemispheric dominance using the brain preference indicator (BPI). We found significant negative correlations between stress and the components of EI, such as emotional awareness and expression, emotional thinking, and emotional regulation. High levels of anger, which is a component of stress, were significantly related to poor emotional regulation. Additionally, emotional application was positively correlated with full-scale IQ scores and scores on the vocabulary, picture arrangement, and block design subtests of the IQ test. High IL-10 levels were significantly associated with low stress levels only in the right-brain-dominant group. High IL-10 and IFN-gamma levels have been associated with high scores of arithmetic intelligence. TNF-alpha and IL-6 were negatively associated with vocabulary scores and full-scale IQ, but IL-10 and IFN-gamma were positively associated with scores on the arithmetic subtest in left-brain-dominant subjects. On the other hand, IL-10 showed positive correlations with scores for vocabulary and for vocabulary and arithmetic in right-brain-dominant subjects. Furthermore, we found significant linear regression models which can show integrative associations and contribution on emotional and cognitive intelligence. Thus, we demonstrated that cytokines, stress, and emotional and cognitive intelligence are closely connected one another related to brain structure and functions. Also, the pro-inflammatory cytokines TNF-alpha and IL-6 had negative effects, whereas the anti-inflammatory cytokines (e.g., IL-10 and IFN-gamma) showed beneficial effects, on stress levels, and multiple dimensions of emotional and cognitive intelligence. Additionally, these relationships among cytokines, stress, and emotional and cognitive intelligence differed depending on right and left hemispheric dominance.

Complex regional pain syndrome (CRPS) and fibromyalgia (FM) share many features. Both can cause severe pain and are considered to have a mechanism of action, including dysfunction of the sympathetic nervous system. However, they have clinical differences in pain range and degree. The present study aimed to find neurophysiologic differences between CRPS and FM using quantitative electroencephalography (QEEG). Thirty-eight patients with CRPS and 33 patients with FM were included in the analysis. Resting-state QEEG data were grouped into frontal, central, and posterior regions to analyze for regional differences. General linear models were utilized to test for group differences in absolute and relative powers. As a result, the CRPS group relative to FM group showed lower total absolute powers in the beta band (F = 5.159, P

Objectives Reducing human errors caused by daytime sleepiness among train drivers is important to prevent train accidents. Our purpose of the study was to investigate the association among sleep, workplace sleeping environments, and human errors. Methods We recruited 144 South Korean train drivers belongs to the Korean Railroad Corporation. This cross‐sectional data was analyzed to investigate the association of insomnia (insomnia severity index), sleep quality (Pittsburgh sleep quality index), obstructive sleep apnea (Berlin questionnaire), and daytime sleepiness (Epworth scale) with human error and near‐miss experiences. We examined whether human error and near‐miss events were associated with various sleeping environments at work and at home after adjusting for the sleep indices. Results The experience of human errors was associated with insomnia and daytime sleepiness, and near‐miss events were associated with insomnia among South Korean drivers. Sleeping environments including cold temperature and odor were related to both human errors and near‐miss events among South Korean train drivers, after adjusted for age, working years, shiftwork, obesity, smoking, binge drinking, regular exercise, caffeine consumption, sleep quality, severity of insomnia, obstructive sleep apnea, and daytime sleepiness. Conclusions The train drivers’ workplace sleeping environment is significantly associated with human error events and near‐miss events after adjusting for sleep quality, insomnia, obstructive sleep apnea, and daytime sleepiness. To prevent train accidents caused by human errors, more attention is necessary for improving workplace sleeping environments.

Purpose Fibromyalgia (FM) and complex regional pain syndrome (CRPS) share many pathological mechanisms related to chronic pain and neuroinflammation, which may contribute to the multifactorial pathological mechanisms in both FM and CRPS. The aim of this study was to assess neuroinflammation in FM patients compared with that in patients with CRPS and healthy controls. Methods Neuroinflammation was measured as the distribution volume ratio (DVR) of [11C]-(R)-PK11195 positron emission tomography (PET) in 12 FM patients, 11 patients with CRPS and 15 healthy controls. Results Neuroinflammation in FM patients was significantly higher in the left pre (primary motor cortex) and post (primary somatosensory cortex) central gyri (p < 0.001), right postcentral gyrus (p < 0.005), left superior parietal and superior frontal gyri (p < 0.005), left precuneus (p < 0.01), and left medial frontal gyrus (p = 0.036) compared with healthy controls. Furthermore, the DVR of [11C]-(R)-PK11195 in FM patients demonstrated decreased neuroinflammation in the medulla (p < 0.005), left superior temporal gyrus (p < 0.005), and left amygdala (p = 0.020) compared with healthy controls. Conclusions To the authors’ knowledge, this report is the first to describe abnormal neuroinflammation levels in the brains of FM patients compared with that in patients with CRPS using [11C]-(R)-PK11195 PET. The results suggested that abnormal neuroinflammation can be an important pathological factor in FM. In addition, the identification of common and different critical regions related to abnormal neuroinflammation in FM, compared with patients with CRPS and healthy controls, may contribute to improved diagnosis and the development of effective medical treatment for patients with FM.

Seventeen years (2001–2017) of surface observations and spatial synoptic classification (SSC) data are used to analyze the characteristics of surface ozone concentration according to synoptic weather patterns. While weather conditions are known to play an important role in regional air quality, the extent to which synoptic weather patterns affect the production of high ground-level ozone concentrations has not yet been fully quantified. Using thermal characteristics and geographic origins, the SSC method classifies air masses into six types: dry polar (DP), dry moderate (DM), dry tropical (DT), moist polar (MP), moist moderate (MM), and moist tropical (MT). We link daily maximum 8-h ozone concentrations (MDA8 O3) from 306 monitoring sites to the closest SSC classifications at 17 airport sites and then analyze their association. We find that DM, DT, and MT are commonly associated with high ozone, whereas DT produces ozone with the greatest efficiency, especially high levels of concentration. This finding implies a potentially strong connection between surface ozone and climate change because the occurrence of DT weather has increased by more than three times over the past 50 years in South Korea. Sensitivity tests reveal that mean MDA8 ozone may increase by 3.5% (7.5%) as the DT frequency increases by 200% (300%). The impacts are larger for higher levels of concentration, with 31.7% (63.3%) or more prevalence of the >80 ppb range with the same increased DT frequency. We conclude that synoptic weather and its long-term trends play important roles in the increased surface ozone recently seen in South Korea.

This study aimed to investigate distinct neurometabolites in the anterior cingulate cortex (ACC), right and left thalamus, and insula of patients with fibromyalgia (FM) compared with healthy controls using proton magnetic resonance spectroscopy (MRS). Levels of N-acetylaspartate (NAA), N-acetylaspartylglutamate (NAAG), total NAA (tNAA = NAA + NAAG), myo-inositol (ml), glutamine (Gln), glutamate (Glu), Glx (Glu + Gln), glycerophosphocholine (GPC), total choline (tCho = GPC + phosphocholine) and glutathione (GSH) levels relative to total creatine (tCr) levels including creatine (Cr) and phosphocreatine (PCr) and relative to Cr levels were determined in the ACC, right and left thalamus, and insula in 12 patients with FM and 13 healthy controls using MRS. In the ACC, NAA/tCr (P = 0.028) and tCho/tCr (P = 0.047) were higher in patients with FM. In the right and left insula, tNAA/tCr (P = 0.019, P = 0.007, respectively) was lower in patients with FM. Patients with FM showed lower levels of ml/Cr (P = 0.037) in the right insula than healthy controls. These findings are paramount to understand decisive pathophysiological mechanisms related to abnormal features in the brain and parasympathetic nervous systems in FM. We suggest that the results presented herein may be essential to understand hidden pathological mechanisms and also life system potential as protective and recovering metabolic strategies in patients with FM.

Surface-level PM10 distribution was estimated from the satellite aerosol optical depth (AOD) products, taking the account of vertical profiles and hygroscopicity of aerosols over Jeju, Korea during March 2008 and October 2009. In this study, MODIS AOD data from the Terra and Aqua satellites were corrected with aerosol extinction profiles and relative humidity data. PBLH (Planetary Boundary Layer Height) was determined from MPLNET lidar-derived aerosol extinction coefficient profiles. Through statistical analysis, better agreement in correlation (R = 0.82) between the hourly PM10 concentration and hourly average Sunphotometer AOD was the obtained when vertical fraction method (VFM) considering Haze Layer Height (HLH) and hygroscopic growth factor f(RH) was used. The validity of the derived relationship between satellite AOD and surface PM10 concentration clearly demonstrates that satellite AOD data can be utilized for remote sensing of spatial distribution of regional PM10 concentration.

Conducting metal oxides such as indium tin oxide (ITO) and Al-doped ZnO have been used for application in transparent conducting electrodes (TCEs), but they are not suitable for flexible transparent electrodes due to their brittleness. Silver nanowires (AgNWs) are one of the most promising alternatives to conducting metal oxides because of their high electrical conductivity and superior ductility, which are essential criteria for flexible optoelectronics. In order to develop high-temperature resistant flexible electrodes, we combined colorless polyimide (CPI) as a backbone matrix substrate with the AgNW network. In this work, we firstly demonstrate the hybrid transparent electrodes of AgNWs-embedded CPI encapsulated by a ZnO layer (ZnO/AgNWs-embedded CPI) via KOH treatment based chemical modification of the CPI film. The ZnO/AgNWs-embedded CPI substrate exhibited a low sheet resistance of 24 Ω sq−1 while maintaining a high optical transparency of 81%. More importantly, the hybrid transparent electrodes exhibited superior thermal stability (heat treatment for 24 hours at 230 °C) with negligible conductivity decay and outstanding bending stability (stable for 10 000 bending cycles). ZnO/AgNWs-embedded CPI showed relatively low roughness (RMS, 9.6 nm) compared with non-embedded AgNWs on CPI (RMS, 82 nm). Embedding of AgNWs on top of the CPI film offers a good potential for application in flexible TCEs with thermal stability.

The recent trend in the air quality degradation of urban South Korea prompted the authors to examine the long-term changes in the near-surface wind speed and its link with the lower atmospheric circulation, using modern reanalysis datasets. Analyses based on JRA-55 data show a negative correlation between near-surface wind speed and static stability over the Yellow Sea and the western part of South Korea. Near-surface wind speed shows a clear declining trend accompanied by increased static stability, while its negative correlation strengthened recently. Further investigations using CMIP5 single-forcing experiments suggest that global warming because of anthropogenic greenhouse gases probably increased static stability in the lower troposphere, implying further atmospheric stagnant conditions in the future.

Mind-body training (MBT) programs are effective interventions for relieving stress and improving psychological capabilities. To expand our previous study which demonstrated the short-term effects of an 8-week online MBT program, the present study investigated whether those short-term effects persist up to a month after the end of the intervention.Among previous participants, 56 (64%) participated in this follow-up study, 25 in the MBT group and 31 in the control group. Outcome measures included the stress response, emotional intelligence, resilience, coping strategies, positive and negative affect, and anger expression of both groups at baseline, at 8 weeks (right after the training or waiting period), and at 12 weeks (a month after the training or waiting period).The MBT group showed a greater decrease in stress response at 8 weeks, and this reduction remained a month after the end of the intervention. The effect of MBT on resilience and effective coping strategies was also significant at 8 weeks and remained constant a month later. However, the improvement to emotional intelligence and negative affect did not persist a month after training.These findings suggest that the beneficial short-term effects of MBT may last beyond the training period even without continuous practice, but the retention of these benefits seems to depend on the outcome variables. Through a convenient, affordable, and easily accessible online format, MBT may provide cost-effective solutions for employees at worksites.

This study reviews the development of shared (community) solar and community choice aggregation in the U.S. states of California and New York. Both states are leaders in energy-transition policy in the U.S., but they have different trajectories for the two forms of energy decentralization. Shared solar is more advanced in New York, but community choice is more advanced in California. Using a field theory framework, the comparative review of the trajectories of energy decentralization shows how differences in restructuring and regulatory rules affect outcomes. Differences in the rules for retail competition and authority for utilities to own distributed generation assets, plus the role of civil society and the attention from elected officials, shape the intensity of conflict and outcomes. They also contribute to the development of different types of community choice in the two states. In addition to showing how institutional conditions associated with different types of restructured markets shape the opportunities for decentralized energy, the study also examines how the efforts of actors to gain support for and to legitimate their policy preferences involve reference to broad social values.

Online mind–body training (MBT) programs can improve the psychological capabilities of practitioners. Although there has been a lot of effort to understand the neural mechanisms underlying the therapeutic effects of meditation, little is known about changes in electroencephalographic (EEG) functional connectivity that accompany mind-body training. The present study aimed to investigate how an online MBT program alters EEG functional connectivity in the default mode network (DMN). We assessed a group of healthcare providers, including 14 females who participated in the 4-week MBT program and 15 females who underwent a 4-week of waiting period. EEG data and information about psychological states were obtained at baseline and 4 weeks. The result was that the intervention group showed significant reductions in anxiety and trait anger that were accompanied by increased global DMN network strengths in the theta and alpha (but not beta and delta) frequency bands; these changes were not observed in the control group. Other variables including state anger, positive and negative affect, and self-esteem have not been changed over time in both groups. These findings suggest that practicing the mind-body training could have a relevance to the functional differences in network related to stress and anxiety reaction.

Catecholamines, including epinephrine (E), norepinephrine (NE), and dopamine (DA), are associated with the response to stressful conditions. However, the relationships of catecholamines with intelligence and their interactions with stress remain unclear. This study assessed stress, intelligence quotient (IQ), and catecholamine levels in 70 healthy subjects to elucidate associations between catecholamines and stress, and between catecholamines and IQ. Additionally, the associations of catecholamines with stress and IQ were analyzed according to hemispheric dominance using the Brain Preference Indicator (BPI). There were positive correlations between the NE/E ratio and the somatization of stress but negative correlations between the E/NE ratio and the somatization of stress among the total number of subjects. In the right-brain-dominant group, a high E/DA ratio was correlated with low levels of stress, somatization and depression, and high NE/E and DA/E ratios were associated with high levels of somatization. In the left-brain-dominant group, high E levels were correlated with low levels of depression. In the total subjects, there were positive correlations between the NE/E and DA/E ratios and the sum of the vocabulary, arithmetic, picture arrangement, and block design IQ subtests. Thus, these catecholamines were associated with stress and IQ, which suggests that the autonomic functional regulation of catecholamine levels in relation to stress may also affect cognitive functions related to intelligence in the brain. Furthermore, the relationships between catecholamines and stress or IQ differed depending on hemispheric dominance, which suggests that the present results could be used to inform the development of personalized therapies based on hemispheric asymmetry.

The immune response is stimulated to protect the body from external antigens and is controlled by several types of immune cells. In the present study, the immunomodulatory effects of Curcuma longa L., purple sweet potato, and mixtures of the two (CPM) were investigated in C57BL/6 mice infected with LP-BM5 murine leukemia virus (MuLV). Mice were divided into seven groups as follows: normal control, infected control (LP-BM5 MuLV infection), positive control (LP-BM5 MuLV infection+dietary supplement of red ginseng 300 mg/kg body weight), the original powder of C. longa L. (C; LP-BM5 MuLV infection+dietary supplement of C 189 mg/kg body weight), the original powder of purple sweet potato (P; LP-BM5 MuLV infection+dietary supplement of P 1811 mg/kg body weight), CPM Low (CPL; LP-BM5 MuLV infection+CPM 2 g/kg body weight), and CPM High (CPH; LP-BM5 MuLV infection+CPM 5 g/kg body weight). Dietary supplementation lasted for 12 weeks. Dietary supplementation of CPM inhibited LP-BM5 MuLV-induced lymphadenopathy and splenomegaly and inhibited reduction of messenger RNA (mRNA) expression of major histocompatibility complex (MHC) I and II. Moreover, CPM reduced the decrease in T- and B cell proliferation, reduced the population of CD4(+)/CD8(+) T cells, and remedied the unbalanced production of T helper-1 (Th1)/T helper-2 (Th2) cytokines in LP-BM5 MuLV-infected mice. In addition, CPM inhibited reduction of phagocytosis in peritoneal macrophages and decreased serum levels of immunoglobulin A (IgA), immunoglobulin E (IgE), and immunoglobulin G (IgG). These results suggest that CPM had a positive effect on immunomodulation in C57BL/6 mice induced by LP-BM5 leukemia retrovirus infection.

In the city, the urban park contributes to the quality of citizen life in many ways, and the importance of the urban park as an urban planning facility is growing each day. In this study, evaluation of park service supply adequacy in Suwon-si, the difference in analysis methods, and the type of land use at urban park catchment area analysis were analyzed. As a result, there were remarkable differences between the two analysis methods. In Suwon-si, the catchment area by network analysis was only about 41% of catchment area by buffer analysis. However, when basic local authorities establish planning of parks and green areas, they use buffer analysis to calculate the park service area. It means that such calculations of urban park service areas may be wider than actually used. Also, because there were differences between urban park catchment areas by land use types, guidelines of planning parks and green areas will be adjusted. Although quantitative expansion of the park area is also important for the realization of green welfare, it is necessary to consider city characteristics such as the population size, population density, land use types, and so on.

- Abstract
Objective: To determine internal medicine (IM) residents' knowledge of, attitudes towards, and barriers to prescribing buprenorphine for opioid use disorder (OUD). Methods: We conducted a cross-sectional study of IM residents across all 35 Accreditation Council for Graduate Medical Education (ACGME) accredited Florida IM residency programs. We used an online survey to collect information about resident demographics, substance use curriculums, career interests, content knowledge about diagnosing and managing OUD, and attitudes about and barriers to prescribing buprenorphine for OUD. We used Chi-square test to explore differences in interest in prescribing buprenorphine. We created a composite knowledge score and investigated distribution of knowledge among characteristics via Mann-Whitney U test. Results: There were 161 participants (response rate 16.0%, n=1008) across 35 programs Seventy-seven percent of residents provided care for patients with OUD more than once per month. Seventy-four percent report no buprenorphine prescribing training. Higher knowledge scores, interest in primary care, being an intern, and caring for patients with OUD more than monthly were associated with interest in obtaining a buprenorphine waiver (P<0.05). Limited knowledge about OUD was the most important barrier to prescribing buprenorphine. Eighty-nine percent support legislation to deregulate buprenorphine. Conclusions: Knowledge about managing OUD was poor and represented the most commonly cited barrier to prescribing buprenorphine. Residents want to expand their role in treating OUD. Our findings warrant incorporating addiction medicine into residency curriculum standards. Legislation removing the buprenorphine waiver requirement may increase the number of resident buprenorphine prescribers and improve treatment options for patients with opioid addiction.

Objective This study investigated peripheral and central metabolites affecting depression, anxiety, suicidal ideation, and anger in complex regional pain syndrome (CRPS) patients. Methods Metabolite levels were determined in the right and left thalamus and insula, in 12 CRPS patients using magnetic resonance spectroscopy (MRS). Results There were positive correlations between valine (Val)/tNAA (N-acetylaspartate+N-acetylaspartylglutamate) and the anxiety, and a negative correlation between glutamine (Gln)/NAA and the depression. There were positive correlations between alanine (Ala)/Gln and the depression and suicidal ideation, between glutamate (Glu)/Gln and the depression and suicidal ideation, between N-acetylaspartylglutamate (NAAG)/Gln and the depression. There was a positive correlation between Ala/NAAG and the trait anger and a negative correlation between creatine (Cr)/N-acetylaspartate (NAA) and the trait anger. There was a negative correlation between Cr/Glx (Glu+Gln) and the trait anger. High hemoglobin and alkaline phosphatase were associated with low pain levels, but CO2 and chloride showed positive correlations with pain levels in CRPS patients. Peripheral glucose, CO2 and chloride were associated with depression, anxiety, anger and suicidal ideation. Conclusion The specific central and peripheral metabolites were associated with psychological disorders including depression, anxiety, suicidal ideation and anger in CRPS patients, showing pathological interactions between a painful body and mind.

We investigated the potential effects of Costaria costata (CC) on atopic dermatitis (AD) development in chloro-2,4-dinitrobenzene (DNCB)-treated NC/Nga mice. CC is a brown alga distributed across the seas of Korea, China, and Japan. A total of 40 mice were randomly assigned to 5 groups with 8 mice per group: untreated Balb/c mice, AD control (0.1% w/v DNCB-treated NC/Nga mice), positive control (i.e., DNCB-treated NC/Nga mice fed a dietary supplement of 66.6 mg/kg of body weight [b.w.] of CJLP133), DNCB-treated NC/Nga mice fed a dietary supplement of 100 mg/kg b.w. of CCE10 (CCE10 100), and DNCB-treated mice fed a dietary supplement of 300 mg/kg b.w. of CCE10 (CCE10 300) groups. The CCE10 100 and CCE10 300 treatment groups suppressed AD development including clinical and histopathological changes and a reduction in skin hydration induced by DNCB. In addition, Th2 cytokine production in primary splenocytes, serum IgE and histamine production, and mast cell infiltration into the skin were suppressed in the CCE10 300 mice compared to the CCE10 100 mice. Our finding demonstrated an inhibitory effect of CCE10 in AD development by means of improving the Th1/Th2 cytokine balance and anti-inflammatory effect in an in vivo model.

Background The therapeutic landscape for acute myeloid leukemia (AML) has become complex with recent drug approvals. CPX-351 has become standard-of-care for patients (pts) with therapy-related AML and AML with myelodysplasia-related changes. Moreover, earlier phase studies combining hypomethylating agents (HMA) and Venetoclax (HMA+Ven) in the frontline setting for elderly patients have demonstrated high response rates and improved survival. Given the overlapping indications, yet lack of comparative outcome data between these therapeutic regimens, treatment decisions have become challenging in the frontline setting. Therefore, we compared the outcomes of newly diagnosed AML pts receiving HMA+Ven vs. CPX-351. Methods We retrospectively annotated 119 pts that received frontline treatment with HMA+Ven and CPX-351 at Moffitt Cancer Center and Memorial Healthcare System between 2013 and 2019. Pts were divided in two cohorts: HMA+Ven (Cohort A) or CPX-351(Cohort B). Via comprehensive chart review of each patient that received HMA+Ven, we further classified a subgroup of pts meeting criteria to receive CPX-351 as CPX-351eligible. Clinical and molecular data were abstracted for each patient in accordance with IRB requirements. Overall response rate (ORR) was the combined total of complete remission (CR), complete remission with incomplete count recovery (CRi), and morphologic leukemia free state (MLFS). Fisher's Exact method was used to determine significance. Kaplan-Meier analysis was performed to estimate median overall survival (mOS) with log-rank test to determine significance. All p-values are two-sided. Results Out of 119 total pts, 41 pts received HMA+Ven (Cohort A) and 78 pts received CPX-351 (Cohort B) with baseline characteristics outlined in Table 1. Among 111 response evaluable pts, ORR was 64.1% in Cohort A, including 28.2% with CR and 28.2% with CRi (Table 2). ORR was 50.0% in Cohort B, comprised of CR in 29.2% and CRi in 18.1%. There was no difference in ORR between Cohort A and Cohort B (64.1% vs. 50%, p 0.17). A significantly greater fraction of pts in Cohort B underwent allogeneic stem cell transplant (allo-SCT) (24.4% vs. 2.4%, p=0.004). ORR was higher in pts with European LeukemiaNet (ELN)-defined favorable/intermediate (fav/int) risk compared to adverse risk group in Cohort A (100% vs. 58.3%, p=0.03), however there was no difference in Cohort B (52.6% vs. 49.1%, p=1.0). ORR was similar among adverse risk groups in both cohorts (58.3% in Cohort A vs. 49.1% in Cohort B, p=0.47). Among responders, median time to best response was significantly longer in Cohort A (61.0 days vs. 40.5 days, p Median follow-up was 6.5 months (mo) in Cohort A and 13.0mo in Cohort B. Median OS was similar in both cohorts (A vs. B, 13.8mo vs. 11.1mo, p=0.82) (Figure 1). Among responders, mOS was NR in Cohort A and 18.2mo in Cohort B (p=0.88) (Figure 2). Compared to Cohort B, mOS was superior for pts with fav/int risk disease in Cohort A (14.2mo (B) vs. NR (A), p=0.045) and not different for adverse risk group (11.1mo (B) vs. 7.3mo (A), p=0.2). Prior HMA exposure was 26.8% in Cohort A and 29.5% in Cohort B for an antecedent hematologic malignancy, however it did not impact mOS (p=0.86) or ORR (p=0.7). Early mortality rates for Cohort A and B were similar at day 30 (2.4% vs. 0%) and day 60 (4.9% vs. 3.8%). Rate of relapse was similar between cohorts A and B (16.0% vs. 30.6%, p=0.24). We then compared the outcomes of pts in Cohort B to CPX-351eligible arm from Cohort A (n=14). ORR and mOS were similar in Cohort B and CPX-351 eligible arm (ORR: 50% vs. 50%, p=1.0; mOS 11.1mo vs. 13.8mo, p=0.43). Only 1 patient (7.1%) of the CPX-351eligible arm underwent allo-SCT. Conclusion Our study demonstrates that HMA+Ven results in comparable response rates and survival outcomes to patients receiving CPX-351 when used as an initial remission therapy for patients with newly diagnosed AML, however the median follow up for patients receiving HMA+Ven was short. Survival did not appear to be impacted by a significantly greater proportion of patients proceeding to allo-SCT in the CPX-351 arm. Overall, HMA+Ven may represent a reasonable frontline remission therapeutic choice in patients with AML and a randomized trial would seem justified.

Background: Older patients with acute myeloid leukemia (AML) have inferior outcomes when compared to younger patients. Hypomethylating agents (HMA) were established as the standard of care for patients who are unfit for intensive induction chemotherapy until HMA and venetoclax (HMA+ven) combination approval by the FDA in December 2018. Approval of HMA+ven was based on an early phase study which produced high response rates; however, the combination was not compared head-to-head with HMA alone. A randomized phase 3 study is currently underway. There is no data available comparing HMA+ven to HMA monotherapy in older patients (age ≥70 years), thus we aimed to characterize responses in older patients when treated with these two regimens. Methods: We retrospectively reviewed clinical and molecular data on 225 patients at Moffitt Cancer Center and Memorial Health System with newly diagnosed AML who were ≥ 70 years old and were treated with HMA monotherapy or HMA+ven combination. Clinical data was abstracted in accordance with institutional review board approved protocol. Patients were then divided in two subgroups: Cohort A) HMA monotherapy and B) HMA+ven combination. We calculated overall response rates (ORR) defined as patients achieving complete remission (CR), CR with incomplete hematologic recovery (CRi) or morphologic leukemia free state (MLFS). Fisher's Exact method was utilized to determine significance for categorical variables. All reported p-values are two sided. Next generation sequencing (NGS) results were analyzed using the TruSight Myeloid-54 gene panel with a sensitivity of 5%, and were characterized in patients treated in cohort B. Results: Among the 225 patients, 87% (n=196) were in cohort A and 13% (n=29) in cohort B. In cohort A, 36.7% were females compared to 27.6% in cohort B. Median age in both cohorts was 76 years (range: 70-90 years in cohort A) (range: 72-86 years in cohort B). Overall, 26% of the patients had adverse risk disease as defined by European Leukemia Net (ELN) classification in cohort A and 51.7% in cohort B. Baseline characteristics are described in Table 1. Overall response rate (ORR) of the entire cohort was 43.6% (n=92) (Table 2). ORR in cohort A was 25.5% (n=47) compared to 66.7% (n=18) in cohort B (p With a median follow up of 11.7 months, the median overall survival (mOS) of the entire cohort was 15.03 months. The median follow-up time in cohort A is 46 months and in cohort B is 5.4 months, making assessment of relapse free survival or overall survival in cohort B premature. Early mortality rate was not different between the two cohorts (1.5% vs 3.4%, p=0.42). Conclusion: Our data provides convincing support that HMA+ven combination yields significantly higher response rates when compared to HMA monotherapy in newly diagnosed AML patients ≥70 years of age; an observation that is further strengthened by the short duration of follow-up in the HMA+Ven cohort. Responses are particularly striking in favorable and intermediate risk patients when treated with HMA+Ven. Overall our data supports the use of HMA+ven in the upfront setting for older patients with newly diagnosed AML. Additional follow-up in HMA+ven arm is needed to evaluate survival outcomes.

Background: Patients with acute myeloid leukemia (AML) with myelodysplasia related changes (MRC) or therapy related myeloid neoplasm have poorer outcomes compared to patients with de novo AML. CPX-351 was approved by the Food and Drug Administration (FDA) in 2017 as an induction chemotherapy regimen for patients with AML-MRC or t-AML as defined by 2016 World Health Organization (WHO) classification. A large randomized phase 3 study that led to approval of CPX-351 included only the patients between age 60 and 75. However, the FDA approval extends to patients of age ≥18 years with limited data regarding its efficacy in a younger patient population. Methods: We performed a retrospective study of clinical and molecular data of 89 patients treated at Moffitt Cancer Center with CPX-351 as frontline induction chemotherapy regimen in patients with AML. Clinical data was abstracted in accordance with institutional review board approved protocol. Patients were then divided in two subgroups: Cohort A) Age Results: Out of a total 89 patients included in the analysis, 17% (n=15) of patients were in cohort A and 83% (n=74) of patients were in cohort B. In cohort A, 40% of patients were female compared to 39% of patients in cohort B. Median age in cohort A was 56 years old (range: 42-59) and 70 years old in cohort B (range: 60-84). Overall, 71% of the patients had adverse risk disease as defined by European Leukemia Net (ELN) classification, which includes 80% of patients in cohort A and 69% of patients in cohort B. Baseline characteristics are described in Table 1. Among 83 patients evaluable for response, overall response rate (ORR) of the entire cohort was 51% (Table 2). ORR in cohort A was 40% compared to 53% in cohort B (p=0.41). ORR in ELN defined adverse risk group was 47% in the entire cohort and was not significantly different between cohort A and B (33% vs. 51%, p=0.34). Overall 30-day mortality rate of the entire cohort was 2.2%, 6.7% in cohort A and 0.1% in cohort B. Overall 60-day mortality rate of the entire cohort was 6.7%, 13.3% in cohort A and 5.4% in cohort B. Overall, 27% of patients proceeded to allogeneic stem cell transplant (allo-SCT), including 20% of patients in cohort A and 28% of patients in cohort B (p=0.75). We then evaluated ORR according to somatic mutations prior to initiation of therapy. The most common gene mutation was ASXL1 in 28% of patients followed by TET2 (25%) and RUNX1 (19%). Patients with IDH1/2 mutations had superior response rates compared to patients without IDH1/2 mutations (13/16 (81%) vs. 67/142 (47%), p=0.02). Among patients with TP53 mutated disease (n=12), which include 20% of patients in cohort A and 13% of patients in cohort B, ORR was 25% with 17% achieving CR and was not significantly different between cohort A and B (p=1.0). At median follow up of 13.0 months, mOS of the entire cohort was 11.1 months. Patients in cohort A did not have significantly different mOS to patients in cohort B (5.8 vs. 11.1 months, p=0.54) (Figure 1). Since there was a higher percentage of patients in cohort A with TP53 mutation than patients in cohort B (20% vs. 13%), we estimated mOS in patients without TP53 mutation and mOS was not different between cohorts A and B (13.4 vs. 11 months, p=0.59). Among responding patients, mOS was not reached in cohort A compared to 17.7 months in cohort B (p=0.59). Conclusion: We demonstrate that CPX-351 results in similar survival outcomes in both younger and older adults with AML with MRC or therapy-related AML. Our data suggests that CPX-351 is a viable treatment option for any age group where inherent disease biology dictates outcome rather than age. Disclosures Padron: Incyte: Research Funding.

Background: Patients with acute myeloid leukemia (AML) have dismal overall outcomes and survival is exceptionally poor in patients who experience relapse or are refractory (R/R) to frontline therapy. Since December 2018, combination therapy with hypomethylating agents (HMA) and venetoclax (HMA+Ven) has become standard frontline therapy for older patients or younger unfit patients. Moreover, it has been routinely utilized in patients experiencing relapsed or refractory AML yet response and outcome data is limited in patients with R/R disease. Thus, we investigated outcomes after HMA+Ven in patients with relapsed or refractory AML. Methods: We retrospectively annotated 72 patients who received treatment with HMA+Ven at Moffitt Cancer Center and Memorial Healthcare System between 2017 and 2019. Patients were divided into two subgroups: 1) initial remission therapy and 2) salvage therapy. Clinical and molecular data were abstracted in accordance with the Institutional Review Board approved protocol. Overall response rate (ORR) included patients achieving complete remission (CR), CR with incomplete count recovery (CRi), and morphologic leukemia free state (MLFS). Patients achieving CR, CRi, or MLFS were termed as responders (RES) and patients without CR, CRi, or MLFS were nonresponders (NRES). Fisher's Exact method was used to determine significance for categorical variables. Kaplan-Meier analysis was performed to determine median overall survival (mOS) and log-rank test was utilized to determine significance. All p-values are two-sided. Results: Out of 72 patients, 41 received HMA+Ven as initial therapy and 31 received it in the R/R setting. Baseline characteristics are outlined in Table 1. Median age was 63 years for patients with R/R AML with 58% female. In the R/R cohort, ORR was 34.5% with 0 (0%) patients achieving CR, 8 (27.6%) patients achieving CRi, and 2 (6.9%) achieving MLFS (Table 2). When compared to patients receiving HMA+Ven as initial therapy, ORR was significantly lower in the R/R cohort (64.1% vs. 34.5%, p=0.03). Among 31 patients in the R/R cohort, 6.5% (n=2) proceeded to allogeneic stem cell transplant (allo-SCT) after achieving CRi. European LeukemiaNet (ELN) risk stratification was known in 22 patients in the R/R cohort and ORR were similar in patients in the favorable/intermediate risk group (n=8) compared to adverse risk group (n=14) (37.5% vs. 28.6%, p=1.0). When compared to HMA+Ven used as initial therapy, ORR among the R/R cohort were not different among adverse risk groups (58.3% vs. 28.6%, p=0.10); however, ORR were significantly lower among patients with favorable/intermediate risk (100% vs. 37.5%, p=0.009). At a median follow-up of 7.6 months (mo), mOS was 4.9mo in the R/R cohort with mOS among RES superior to NRES (not reached vs. 2.4mo, p=0.0009) (Figure 1). Moreover, mOS was inferior in R/R patients compared to initial therapy (4.9mo vs. 13.8mo, p=0.0013) (Figure 2). A total of 15 (48.4%) patients had HMA exposure prior to receiving HMA+Ven without apparent impact on mOS (3.7mo (prior HMA) vs. 4.9mo (no prior HMA), p=0.97). The median duration of CR/CRi was 5.2mo and the median time to CR/CRi was 2.4mo. Based on ELN risk groups, mOS was not statistically different among patients with favorable/intermediate risk disease compared to adverse risk disease (8.6mo (fav/int) vs. 2.8mo (adverse), p=0.07). Responses were also analyzed based upon somatic mutations (Figure 2). In patients with isocitrate dehydrogenase 1 and 2 mutations (IDH1/IDH2) compared to patients without IDH1/2, ORR were 60% vs. 25%, respectively (p=0.28) with no significant difference in mOS (7.2mo (IDHmut) vs. 3.1mo (IDHwt), p=0.38). Comparing patients with TP53 mutation to those without TP53 mutations, no significant difference in ORR (25% vs. 33%, p=1.0) or mOS (4.4mo vs. 6.9mo, p=0.0.84) was noted. Conclusion: Although combination therapy with HMA+Ven has yielded impressive responses as frontline therapy, response rates with this combination in the salvage setting are less encouraging with the possible exception of those patients with IDH1/IDH2 mutations. Nevertheless, responders to salvage HMA+Ven had a significant survival benefit compared to nonresponders, suggesting that this combination is a reasonable salvage option in patients with relapsed or refractory AML.

Objective: Long-acting injectable (LAI) antipsychotics, such as paliperidone palmitate (PP), are known to improve treatment adherence in patients with schizophrenia, which can lead to reductions in relapse and hospitalization rates. However, relatively few studies have demonstrated the economic impact of LAIs, especially in Asian populations. Methods: We conducted a claim-based mirror-image study to explore changes in healthcare utilization and associated costs, among 1,272 South Korean patients with schizophrenia (ICD-10-CM code F20), between the 1-year periods before and after the initiation of PP treatment. Results: Patients accessed outpatient services more frequently after versus before starting PP treatment, with the number of prescription days increasing by 133.45 (p < 0.0001) and the associated costs increasing by USD 1,497.15 (p < 0.0001). The number of admission days was reduced by 11.33 after starting PP treatment (p < 0.0001) and the associated costs were reduced by USD 1,220.75 (p < 0.0001). However, admission cost savings were different according to patients' oral drug compliance. The daily dosages for benztropine, procyclidine, and propranolol decreased, showing that there were fewer side-effects after PP-treatment (p < 0.0001). Conclusion: Although the high acquisition cost of PP has been regarded as an obstacle to its clinical use, our results imply that the high prescription costs for PP may be counterbalanced by the reduced admission costs associated with its use. Economic outcomes for patients treated with LAIs should be investigated further to help healthcare decision-makers and providers to determine the value of LAIs relative to other treatment medications.
