Abstract
Although accurate intracranial pressure (ICP) monitoring is essential for the diagnosis and treatment of severe brain diseases, current methods are performed invasively. Therefore, a safe and less invasive ICP measurement is required. The purpose of our study was to develop a simplified cranial cavity model for a better understanding of the relationship between the ICP and the pressure measurement within the dural venous sinus (DVS) to support the validity of using sinus pressure as the surrogate of the ICP. The in-house cranial cavity model had three components: the brain part, the DVS part, and the subarachnoid space (SAS) part. Pressure in other parts was measured when the pressure in the SAS part and, separately, brain part was increased from 0 (baseline) to 50 mmHg at intervals of 10 mmHg. When the pressure in the SAS part was increased from 10 to 50 mmHg at 10 mmHg interval, pressures of both the brain and DVS parts increased without significant difference (all P > 0.05). However, pressures in both the SAS and DVS parts differed while the pressure in the brain part was increased. The pressures in both parts showed about 70% of the increase in the brain part. Nevertheless, the pressures in the SAS and DVS parts were not significantly different (P > 0.05). A simplified in-house cranial cavity model was developed consisting of three compartments to represent the actual intracranial spaces. The pressure measurement within the DVS was feasible to use as a surrogate for the ICP measurement.

Abstract
Astragalus membranaceus and Cinnamomum cassia are used as spices and flavorful ingredients, or medicinal herbs with pharmacological effects. In this study, the hair-growth-promoting effects of the YH complex, a newly developed formula consisting of membranaceus and C. cassia, are investigated with the prediction of its molecular mechanism. The target gene of the YH complex was about 74.8% overlapped with the gene set of 'Hair growth' on the GO Biological Process database. The oral administration of the YH complex promoted hair regrowth and increased hair-shaft thickness in depilated hair loss mice. In addition, the anagen/telogen hair follicle ratio was significantly increased by the YH complex. The growth factors affecting the growth of hair follicles were dose-dependently increased by treatment with the YH complex. The Wnt/β-catenin signaling pathway expressions in skin tissues were apparently increased by the administration of the YH complex. In conclusion, the YH complex consisting of A. membranaceus and C. cassia induced hair follicle differentiation and preserved the growing-anagen phase by increasing growth factors and the Wnt/β-catenin signaling pathway, leading to the restoration of hair loss. The YH complex can be a remedy for hair loss diseases, such as alopecia areata, androgenetic alopecia, telogen effluvium, and chemotherapy-induced alopecia.

Abstract
It is known that animal-origin medicine could be one of effective treatment to remedy atopic dermatitis (AD) by controlling the cytokines. Cicadidae Periostracum (CP), the slough of Cryptotympana pustulata, has been frequently used for treating AD and skin affliction in traditional Korean Medicine. This study is aimed at investigating the ameliorating effects of CP on AD and its potential mechanism. The dinitrochlorobenzene sensitized mice were treated with CP for 2 weeks. The various biomarkers and the dermatitis scores presented that CP treatment can induce the visual and biological improvements of AD model. Pruritus, the most serious symptom of AD, which can cause repeated scratching behaviors and finally lead to lichenification, was reduced with CP treatment by regulating the inflammatory reactions. In addition, CP treatment diminished the number of mast cells that are known for causing inflammatory reactions. Moreover, it is proven that CP can decline secretion of interleukin-22, which means CP treatment has anti-inflammatory effects. CP treatment can correct the imbalance of helper T (Th)1 and Th2, downregulating thymic stromal lymphopoietin that leads to decrease of mRNA level of inflammatory cytokines. The crucial role of CP treatment is controlling of the Janus kinase 1/signal transducer and activator of transcription 3 pathway. In addition, CP treatment has the inhibitory effects on kallikrein related peptidase (KLK) 5 and KLK7. Taken together, CP treatment can ameliorate most symptoms and problems caused by AD disease, improving the AD patients' life quality.

Abstract
The inhibition of bone loss remains a challenge for postmenopausal women, considering the fact that only three anabolic treatments for osteoporosis have been approved by the FDA. This study aimed to investigate the osteogenic capacities of Osteo-F, a newly developed herbal formula, upon integrating network analysis and pre-clinical studies into clinical trials. The network pharmacology analysis showed that a potential mechanism of Osteo-F is closely related to osteoblast differentiation. Consistent with the predicted mechanism, Osteo-F treatment significantly enhanced bone matrix formation and mineralization with collagen expression in osteoblasts. Simultaneously, secreted bone-forming molecules were upregulated by Osteo-F. After the administration of Osteo-F to osteoporotic mice, the femoral BMD and osteocalcin in the serum and bone tissues were significantly improved. Subsequently, a randomized, double-blinded, placebo-controlled clinical trial showed that 253 mg of Osteo-F supplementation for 24 weeks resulted in significant improvements in the Z-score and serum osteocalcin levels of postmenopausal women compared to the placebo, thus indicating bone anabolic efficacy. In the current study, the bone anabolic effect of Osteo-F was determined by activating the differentiation and mineralization of osteoblasts through integrating experiments based on network analysis into clinical trials, with synchronized, reliable evidence, demonstrating that Osteo-F is a novel bone anabolic treatment in postmenopausal women.

Abstract
We have developed a new scintillator-based optical soft x-ray (OSXR) diagnostic system for KSTAR. By utilizing fiber optic faceplates, mm-size lens arrays, and fiber bundles, we have successfully constructed a novel optical system for scintillator-based soft x-ray detection to overcome the limited vacuum-port conditions in KSTAR. P47 (Y2SiO5), which has a fast rise (∼7 ns) and decay (∼100 ns) time sufficient for detecting plasma instabilities observed in the kHz-MHz spectral range, was selected as the scintillator material for the KSTAR OSXR system. Scintillation toward each detection channel is collected by the lens arrays coupled to optical fiber cores, which are connected to the photodetector system. Initial results obtained during the 2022 KSTAR experimental campaign support the validity of the OSXR data through the consistency of OSXR measurement results with other diagnostics. We also observe that the OSXR system can capture magnetohydrodynamic activities, such as sawtooth oscillations, and provide valuable information for disruption mitigation studies using shattered pellet injection.

Abstract
Abies holophylla is an evergreen coniferous species that has been widely used for treating pulmonary diseases and colds. Previous research has demonstrated the anti-inflammatory effect of Abies species and the anti-asthmatic activities of Abies holophylla leaf essential oil (AEO). As asthma and allergic rhinitis (AR) share pathophysiology and pharmacotherapeutic interventions, AEO inhalation can also ameliorate upper respiratory allergic diseases. This study explored the protective effects of AEO on AR with network pharmacological pathway prediction. The potential target pathways of AEO were analyzed by a network pharmacological approach. The BALB/c mice were sensitized by ovalbumin (OVA) and 10 μm particular matter (PM10) to induce allergic rhinitis. Aerosolized AEO 0.0003% and 0.03% were delivered by nebulizer for 5 min a day, 3 times a week for 7 weeks. Nasal symptoms (sneezing and rubbing), histopathological changes in nasal tissues, serum IgE, and zonula occludens-1 (ZO-1) expressions on nasal tissues were analyzed. After AR induction with OVA+PM10 and inhalation of AEO 0.0003% and 0.03% treatment, AEO significantly decreased allergic symptoms (sneezing and rubbing), hyperplasia of nasal epithelial thickness, goblet cell counts, and serum IgE level. The network analysis demonstrated that the possible molecular mechanism of AEO is highly associated with the IL-17 signaling pathway and tight junction. The target pathway of AEO was investigated in RPMI 2650 nasal epithelial cells. Treatment of AEO on PM10-treated nasal epithelial cells significantly reduced the production of inflammatory mediators related to the IL-17 signaling pathway, NF-κB, and the MAPK signaling pathway and prevented the reduction in TJ-related factors. When taken together, AEO inhalation may be considered as a potential treatment for AR by alleviating nasal inflammation and recovering the tight junction.

Abstract
Obesity is caused by the accumulation of excess lipids caused by an energy imbalance. Differentiation of pre-adipocytes induces abnormal lipid accumulation, and reactive oxygen species (ROS) generated in this process promote the differentiation of pre-adipocytes through mitogen-activated protein kinase (MAPK) signaling. Peroxiredoxin (Prx) is a potent antioxidant enzyme, and peroxiredoxin 5 (Prx5), which is mainly expressed in cytosol and mitochondria, inhibits adipogenesis by regulating ROS levels. Based on previous findings, the present study was performed to investigate whether cytosolic Prx5 (CytPrx5) or mitochondrial Prx5 (MtPrx5) has a greater effect on the inhibition of adipogenesis. In this study, MtPrx5 decreased insulin-mediated ROS levels to reduce adipogenic gene expression and lipid accumulation more effectively than CytPrx5. In addition, we found that p38 MAPK mainly participates in adipogenesis. Furthermore, we verified that MtPrx5 overexpression suppressed the phosphorylation of p38 during adipogenesis. Thus, we suggest that MtPrx5 inhibits insulin-induced adipogenesis more effectively than CytPrx5.

Abstract
Background Recently, for various reasons, the need for non-invasive treatment for localized fat has emerged. This study confirmed whether Magnolia officinalis (MO) pharmacopuncture reduces localized fat by promoting lipolysis and inhibiting adipogenesis. Methods The network was built using genes related to the active compound of MO and the mode of action of MO was predicted by the functional enrichment analysis. Based on the result from network analysis, 100 µL of 2 mg/mL MO pharmacopuncture was injected into the inguinal fat pad for 6 weeks in obese C57BL/6J mice. Normal saline was injected into the right-side inguinal fat pad as a self-control. Results It was expected that the 'AMP-activated protein kinase (AMPK) signaling pathway' would be affected by the MO Network. MO pharmacopuncture reduced the weight and size of inguinal fat in HFD-induced obese mice. The phosphorylation of AMPK along with the increases of lipases was significantly increased by MO injection. Also, the expression levels of fatty acid synthesize-related mediators were suppressed by MO injection. Conclusion Our results demonstrated that MO pharmacopuncture promoted the expression of AMPK, which has beneficial effects on activation of lipolysis and inhibition of lipogenesis. Pharmacopuncture of MO can be a non-surgical alternative therapy in the treatment of local fat tissue.

Abstract
Allergic rhinitis is one of the most common diseases, which is caused by IgE-mediated reactions to inhaled allergens. Essential oils from the Mentha piperita leaf (EOM) are known to be effective for various diseases, such as respiratory diseases. However, the effect of inhalation of EOM on tight junctions and inflammation related to allergic rhinitis is not yet known. The purpose of this research was to explain the effects of the inhalation of EOM on tight junctions and inflammation of allergic rhinitis through network pharmacology and an experimental study. For that purpose, a pharmacology network analysis was conducted comprising major components of EOM. Based on the network pharmacology prediction results, we evaluated the effect of EOM on histological changes in mice with ovalbumin and PM10-induced allergic rhinitis. Allergic symptoms, infiltration of inflammatory cells, and regulation of ZO-1 were investigated in mice with allergic rhinitis. Other allergic parameters were also analyzed by reverse transcription polymerase chain reaction and western blot in nasal epithelial cells. In the network analysis, the effects of EOM were closely related to tight junctions and inflammation in allergic rhinitis. Consistent with the results from the network analysis, EOM significantly decreased epithelial thickness, mast cell degranulation, goblet cell secretion, and the infiltration of inflammatory cells in nasal tissue. EOM also regulated the MAPK-NF-κB signaling pathway, which was related to tight junctions in nasal epithelial cells. This research confirmed that inhalation of EOM effectively restores tight junctions and suppresses inflammation in the allergic rhinitis model. These results reveal that EOM has a therapeutic mechanism to treat allergic rhinitis.

Abstract
Aim
Women who inevitably underwent surgical hysterectomy before natural menopause may have an earlier increase in hematocrit and storage iron than women who continue menstruation, thereby increasing the risk of cardiovascular disease (CVD) early. We aimed to evaluate the association of women with hysterectomy vs. without hysterectomy before their 50s with the risk of incident CVD.
Methods
This was a retrospective-cohort study, 135,575 women aged 40 to 50 years in 2011–2014 were extracted from the Korean Health Insurance Review and Assessment Service data and after propensity score matching, 55,539 pairs were included in hysterectomy and non-hysterectomy group respectively. The primary endpoint was major adverse cardiac and cerebrovascular events (MACCE), a composite of cardiovascular death, myocardial infarction (MI), stroke, and coronary artery revascularization.
Results
After adjustment for confounding factors, hysterectomy group had an increased risk of MACCE compared with non-hysterectomy group (hazard ratio [HR], 1.25; 95% confidence interval [CI], 1.09–1.44). Regarding individual outcomes, cardiovascular death, MI, and coronary revascularization were comparable between the groups, whereas, the risk of stroke was significantly higher in hysterectomy group than non-hysterectomy group (HR, 1.31; 95% CI, 1.12–1.53). Even after excluding women who underwent oophorectomy, hysterectomy group had a higher risk of MACCE than non-hysterectomy group (HR, 1.24; 95% CI 1.06–1.44).
Conclusions
Early surgical menopause due to hysterectomy, not hormonal menopause, was associated with an increased risk for a composite of CVD, especially stroke. This suggest that the role of “uterus” as well as sex hormones may be important for the sharp increase in the risk of CVD in women after menopause.

Abstract
Background
Although active rhythm control by atrial fibrillation (AF) catheter ablation (AFCA) reduces left atrial (LA) dimension, blunted atrial reverse remodeling can be observed in patients with significant atrial myopathy. We explored the characteristics and long-term outcomes of AF patients who showed blunted atrial reverse remodeling despite no AF recurrence within a year after AFCA.
Methods
Among a total of 2,756 patients with AFCA, we included 1,685 patients (74.8% male, 60.2±10.1 years old, 54.5% paroxysmal AF) who underwent both baseline and 1-year follow-up echocardiogram, baseline LA>40mm, and did not recur within a year. We divided them into tertile groups (T1–T3) based on one-year percent change of LA dimension after propensity matching for age, sex, AF type, and baseline LA dimension. We also investigated the patients' genetic characteristics with blunted LA reverse remodeling (T1) using a genome-wide association study (GWAS).
Results
Patients with blunted LA reverse remodeling (T1, n=424) were independently associated with body mass index (OR 1.082 [1.010–1.160], p=0.025), LA peak pressure (OR 1.010 [1.002–1.019], p=0.019), LA wall thickness (OR 0.448 [0.252–0.789], p=0.006), LA voltage (OR 0.651 [0.463–0.907], p=0.012), and pericardial fat volume (OR 1.004 [1.001–1.008], p=0.014). Throughout 65.9±37.4 months of follow-up, the incidence of AF recurrence a year after the procedure was significantly higher in the T1 group than in T2 or T3 groups (Log-rank p<0.001). Among 894 patients with GWAS, ATXN1, XPO7, KRR1_PHLDA1, ZFHX3, and their polygenic risk score were associated with blunted LA reverse remodeling.
Conclusions
Patients with blunted LA reverse remodeling after AFCA were independently associated with low LA voltage, thin wall thickness, high LA pressure, and fat volume, and have a genetic background. Long-term clinical recurrence a year after AFCA was higher in this patient group with suspicious atrial myopathy.

Abstract
BACKGROUND Asthma is one of the most common chronic inflammatory diseases of the airways. Essential oil from Abies holophylla leaf (EOA) has been reported to have anti-inflammatory property. This study aimed to predict the inhibitory effect of EOA against asthma by network analysis and to confirm the underlying mechanism of EOA on airway inflammation. PURPOSE AND STUDY DESIGN The effects and underlying mechanisms of EOA on asthma were investigated by in silico network pharmacology and an experimental in vivo study. METHODS To define the effectiveness of EOA on asthma, the network pharmacology was constructed using major components of EOA. EOA (0.0003 and, 0.03 v/v%) was aerosolized by nebulizer 3 times a week for 5 min for 7 weeks. After 3 weeks of treating the mice with EOA, asthma was induced by sensitizing them with ovalbumin (OVA) and PM10. The effects of EOA on the IL-17 related signaling pathway was confirmed using an asthmatic model. RESULTS The network analysis showed that EOA is highly associated with the IL-17-related signaling pathway. EOA inhibited respiratory epithelium hyperplasia, collagen deposition and goblet cell activation in the lung and trachea tissues. In addition, EOA reduced the number of eosinophils, lymphocytes and macrophages in BALF. Furthermore, in the asthmatic model of mice, we showed that EOA inhibited IL-17-related cytokines, increased Treg-related cytokines and decreased the TRAF6 and MAPK and, suppressed the nuclear transcriptional activities of NF-kB. CONCLUSIONS The network pharmacology and in vivo study indicated that EOA may have an inhibitory effect on airway inflammation in asthma exposure through the IL-17-related signaling pathway.

Abstract
Banhasasim-tang (BST), a herbal medicine, has been used for nausea and fever from cold damage. This study aimed to investigate the protective effects of BST in cold restraint stress-induced gastric ulcers. Male Sprague Dawley rats were orally treated with various doses of BST including 0.25, 0.5, 1, 3, 6, 9, 12 and 18g/kg based on the human daily intake dose. After treatment once per day for 3 days, rats were restrained into the cold stress chamber for 12h at 4°C to induce gastric ulcers. Gastric hemorrhagic ulcer area was evaluated and serum adrenocorticotropic hormone (ACTH), corticosterone, epinephrine and dopamine levels were determined. Compared to cold stress-induced gastric ulcer rats, hemorrhage ulcer areas were reduced in BST-treated stomach tissues at all concentrations. Increased serum ACTH, corticosterone and epinephrine levels were significantly decreased by BST treatment in cold stress-induced gastric ulcer rats. Moreover, there were increments of serum dopamine levels in 3 and 6g/kg of BST-treated groups. Taken together, BST positively ameliorated cold restraint stress-induced gastric hemorrhage with decrease in serum stress-related biomarkers such as ACTH, corticosterone, epinephrine and dopamine. The 3-6-fold of human daily intake dose of BST exhibited protective effects as a herbal medicine for gastric ulcers.

Abstract
Phlomis umbrosa has been traditionally used for bone diseases in traditional Korean Medicine. Sweroside (SOS), marker compounds of P. umbrosa, has been known to promote osteoblast differentiation. In this study, ameliorative effects of SOS on osteoporosis and potential target pathway were investigated. Ovariectomized mice were administered three doses of SOS three times a week for 4 weeks after inducing osteoporosis. Bone mineral content (BMC) and bone mineral density (BMD) were analyzed by dual energy X-ray absorptiometry. A human osteosarcoma cell line (SaOS-2) was differentiated to clarify the promoting effects of SOS on osteoblast differentiation and bone formation. Osteoblastic bone-forming markers were evaluated in lumbar vertebrae (LV) and mineralized SaOS-2 cells. SOS markedly elevated BMC and BMD levels and attenuated the bone marrow adipocytes in the femoral shaft. SOS increased the formation of bone matrix in SaOS-2 cells. Bone morphogenetic protein-2 (BMP2) and runt-related transcription factor 2 (CBFA1) in LV and SaOS-2 cells were up-regulated by SOS. SOS increased alkaline phosphatase (ALPL), osteopontin (SPP1), and bone sialoprotein-1 (BSPH1). In conclusion, SOS induced the formation of mineralized bone matrix by regulating BMP2/CBFA1-mediated molecules. Therefore, SOS could be a therapeutic compound of treatment for osteoporosis by producing the new bone matrix.

Abstract
Strategies for cancer treatment have traditionally focused on suppressing cancer cell behavior, but many recent studies have demonstrated that regulating the tumor microenvironment (TME) can also inhibit disease progression. Macrophages are major TME components, and the direction of phenotype polarization is known to regulate tumor behavior, with M2-like polarization promoting progression. It is also known that reactive oxygen species (ROS) in macrophages drive M2 polarization, and M2 polarization promote lung cancer progression. Lung cancer patients with lower expression of the antioxidant enzyme peroxiredoxin 5 (Prx5) demonstrate poorer survival. This study revealed that Prx5 deficiency in macrophages induced M2 macrophage polarization by lung cancer. We report that injection of lung cancer cells produced larger tumors in Prx5-deficit mice than wild-type mice independent of cancer cell Prx5 expression. Through co-culture with lung cancer cell lines, Prx5-deficient macrophages exhibited M2 polarization, and reduced expression levels of the M1-associated inflammatory factors iNOS, TNFα, and Il-1β. Moreover, these Prx5-deficient macrophages promoted the proliferation and migration of co-cultured lung cancer cells. Conversely, suppression of ROS generation by N-acetyl cysteine (NAC) inhibited the M2-like polarization of Prx5-deficient macrophages, increased expression levels of inflammatory factors, inhibited the proliferation and migration of co-cultured lung cancer cells, and suppressed tumor growth in mice. These findings suggest that blocking the M2 polarization of macrophages may promote lung cancer regression.

Abstract
Localized adiposity is a serious aesthetic problem and a well-known health risk factor. There is a growing interest in minimally invasive treatment options for excessive fat accumulation, such as pharmacopuncture. LIPOSA is a newly developed pharmacopuncture formula from three natural herbs: The tuber of Pinellia ternata (Thunb.) Breitenb., the whole plant of Taraxacum platycarpum Dahlst. and the root of Astragalus membranaceus Bunge. The present study investigated the effects of pharmacopuncture treatment with LIPOSA on localized adiposity. Male C57BL/6J mice were fed high fat diet for 8 weeks to induce obesity. Then, 100 µl LIPOSA was injected into the left-side inguinal fat pad at various concentrations, including 13.35, 26.7 and 53.4 mg/ml. Normal saline was injected into the right-side inguinal fat pad of each mouse as a control. The treatment was performed three times per week for 2 weeks. The weight and histological changes were analyzed in the inguinal fat pad of the obese mice. The expression levels of adipose triglyceride lipase (ATGL), hormone-sensitive lipase (HSL), autophagy-related gene (ATG)5, ATG7 and LC3-II, as lipophagy-related factors, were evaluated to confirm the lipid-catabolic effects of LIPOSA. LIPOSA pharmacopuncture markedly decreased the weight of the fat tissue and the size of the adipocytes in the inguinal region of the mouse models of obesity in a dose-dependent manner. The expression levels of ATGL, HSL, ATG5, ATG7 and LC3-II were significantly increased by the LIPOSA treatments. In addition, LIPOSA pharmacopuncture was found to decrease the expression levels of ACC, PPAR-γ and PEPCK. The results indicated that subcutaneous injection of LIPOSA can degrade local fat and induce lipophagic and lipase activation effects. In addition, lipid metabolism related to fat accumulation was regulated by the LIPOSA treatment. The present study suggests that LIPOSA pharmacopuncture can be a non-surgical alternative in the treatment of localized adiposity.

Abstract
Localized fat deposits are associated with health and aesthetic problems that mainly affect a large proportion of individuals. Recently, bioactive constituents of TP have been reported to affect lipid metabolism. In this study, we performed a network pharmacological analysis to assume potential lipolytic effects of TP and investigated the actual lipolytic effects of TP extract injection on local body fat and its underlying mechanism. Using the genes related to active compounds of TP, the network was constructed. Through the Functional Enrichment Analysis, Lipid Metabolism and Fatty Acid Metabolism were expected to be affiliated with the network, which implied possible lipolytic effects of TP. On the comparison between TP network and Obesity-related Gene Sets, about three-fourths of elements were in common with the gene sets, which indicated a high relevance between TP and obesity. Based on the genes in lipolysis-related pathways, Perilipin, CGI-58, ATGL, HSL and MGL were selected to identify the actual lipolytic effects of TP. TP injection reduced the inguinal fat weight. Also, the diameter of the adipocytes was decreased by the TP treatment in HFD-induced obese mice. In addition, TP suppressed lipid accumulation in differentiated 3T3-L1 adipocytes. Moreover, because the expression of Perilipin was increased, CGI-58, ATGL, HSL and MGL were markedly decreased. Furthermore, glycerol release was down-regulated by the TP treatment. TP exerted its lipolytic effects by regulating the lipolysis machinery through stimulation of lipases. Based on the present findings, TP is expected to be a potent component of injection lipolysis for removing localized body fat.

Abstract
BACKGROUND Pine nut oil (PNO), a standardized and well-defined extract of Pinus koraiensis (Korean pine), has beneficial effects on wound healing, inflammatory diseases, and cancer. However, the explanation for the mechanism by which PNO reduces body fat remains uncertain. We performed a protein-protein interaction network (PPIN) analysis to explore the genes associated with pinolenic acid using the MEDILINE database from PubChem and PubMed. It was concluded through the PPIN analysis that PNO was involved in a neutral lipid biosynthetic process. PURPOSE This study evaluated the effects of PNO predicted by the network analysis of fat accumulation in chronic obesity mouse models established by feeding a high fat diet (HFD) to C57BL/6J mice and explored potential mechanisms. METHODS HFD mice were fed only HFD or HFD with PNO at 822 and 1644 mg/kg. After an oral administration of 7 weeks, several body weight and body fat-related parameters were examined, including the following: adipose weight, adipocyte size, serum lipid profiles, adipocyte expression of PPAR-γ, sterol regulatory element binding protein (SREBP)-1c, lipoprotein lipase (LPL) and leptin. RESULTS We showed that oral administration of PNO to HFD mice reduces body fat weight, fat in tissue, white adipose tissue weight, and adipocyte size. The serum cholesterol was improved in the HFD mice treated with PNO. Additionally, PNO has significantly attenuated the HFD-induced changes in the adipose tissue expression of PPAR-γ, SREBP-1c, LPL, and leptin. CONCLUSIONS The findings from this study based on the PPIN analysis suggest that PNO has potential as drug to reduce body fat through fat regulatory mechanisms by PPAR-γ and SREBP-1c.

Abstract
Osteoporosis is a common skeletal disease in post-menopausal women. Palmul-tang, an herbal medicine, has been treated for gynecological disease such as anemia, anorexia, anti-fatigue, unspecified menstruation and female infertility in East Asia. In this study, ameliorative effects of Palmul-tang soft extracts (PMT), a Korean Medicine, on osteoporosis were investigated. Ovariectomized (OVX) osteoporotic ICR mice were intragastrically administrated PMT for 4 weeks. The level of bone mineral density (BMD) was analyzed in bone tissues by dual X-ray absorptiometry. The bone medullary cavity and deposition of collagen were investigated by histological analysis. In addition, the BMP-2 signaling-related molecules, osteoblastic differentiation and formation markers, were determined in femoral tissues. The levels of BMD and bone mineral content were significantly increased in tibia, femurs and LV by treatment of PMT. PMT replenished bone marrow cavity and increased collagen deposition in bone marrow cells of femur. In addition, administration of PMT recovered serum ALP, bALP, osteocalcin and calcium levels in osteoporotic mice. Moreover, PMT treatment up-regulated the expressions of BMP-2, RUNX2 and OSX with its downstream factors, ALP, OPN and BSP-1, in the femoral tissues. Taken together, PMT restored the bone minerals and improvement of bone integrity by bone-forming BMP-2 signaling pathway. These results demonstrate that PMT could be an ameliorative agent for osteoporosis.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The fruit of Schizandra chinensis and Lycium chinense, and the root of Eucommia ulmoides, components of Osteo-F, has traditionally been used for treating bone diseases in Korean Medicine. AIM OF THE STUDY The exact role and underlying mechanism of Osteo-F herbal formula on bone formation in osteoporosis was investigated in the present study. MATERIALS AND METHODS OVX mice were treated with 0.9, 9 and 90 mg/kg of Osteo-F for 4 weeks. Bone tissues including fourth to sixth lumbar vertebrae (LV) and femur were collected to analyze the bone mineral density (BMD). In addition, serum biomarkers were estimated by enzyme-linked immunosorbent assay. The expressions of collagen, BMP-2 and osteopontin were determined in tibia to clarify the bone anabolic effects of Osteo-F in osteoporosis. RESULTS The levels of BMD in both of fourth to sixth LV and femur were significantly increased by Osteo-F treatment in OVX mice. Bone mineral content (BMC) was also elevated in Osteo-F-treated LV and femoral bone tissues. In addition, serum osteocalcin was markedly increased by Osteo-F in osteoporotic mice. Serum ALP and bALP levels were neutralized in Osteo-F 90 mg/kg-administered mice. Furthermore, Osteo-F treatment dramatically increased the mRNA expressions of collagen type I, BMP-2 and OPN in tibial bone specimens. CONCLUSIONS Osteo-F ameliorated bone loss by increasing bone forming molecules including BMP-2 and OPN in osteoporosis. Osteo-F, a newly developed herbal formula, may be an alternative material for the management of osteoporosis with bone anabolic effects.

Abstract
Objectives: Although glutamate is an essential factor in the neuronal system, excess glutamate can produce excitotoxicity. We previously reported that Peroxiredoxin 5 (Prx5) protects neuronal cells from glutamate toxicity via its antioxidant effects. However, it is unclear whether cytosolic or mitochondrial Prx5 provides greater neuroprotection. Here, we investigated differences in the neuroprotective effects of cytosolic and mitochondrial Prx5. Methods: We analyzed patterns of cytosolic and mitochondrial H2O2 generation in glutamate toxicity using HyPer protein. And then, we confirmed the change of intracellular ROS level and apoptosis with respective methods. The mitochondrial dynamics was assessed with confocal microscope imaging and western blotting. Results: We found that the level of mitochondrial H2O2 greatly increased compared to cytosolic H2O2 and it affected cytosolic H2O2 generation after glutamate treatment. In addition, we confirmed that mitochondrial Prx5 provides more effective neuroprotection than cytosolic Prx5. Discussion: Overall, our study reveals the mechanisms of cytosolic and mitochondrial ROS in glutamate toxicity. Our findings suggest that mitochondrial ROS and Prx5 are attractive therapeutic targets and that controlling these factors be useful for the prevention of neurodegenerative diseases.

Abstract
Atopic dermatitis (AD) is a chronic cutaneous disorder that is characterized by severe eczematous inflammation, swelling, and lichenification. Activation of T helper (Th)-22 cells by allergens leads to epidermal hyperplasia with hyperkeratosis at the chronic phase of AD. Derma-Hc is composed of five natural herbs with anti-AD effects, such as Astragalus membranaceus BUNGE, Schizonepeta tenuifolia Briq., Cryptotympana pustulata Fabr., Angelica sinensis Diels, Arctium lappa L. In this study, the ameliorative effect of Derma-Hc on cutaneous lichenification in 2,4-dinitrochlorobenzne (DNCB)-induced AD was investigated. The dorsal skin of mice was sensitized with DNCB to induce AD-like skin lesions. The dermatitis score and frequency of scratching were evaluated. Thickness of epidermis and dermis was measured by staining with H&E. In addition, infiltration of the mast cell was observed by staining with toluidine blue. Then, desmosomal cadherin, DSC1 was examined by immunofluorescence. Pathological mechanisms involved in lichenification were analyzed in AD-like skin lesions and TNF-α + IFN-γ-treated with human keratinocytes including keratinocyte differentiation genes and JAK1-STAT3 signaling pathway with IL-22 by RT-PCR and western blotting. Topical treatment of Derma-Hc improved AD-like symptoms such as dryness, edema and lichenefication and decreased the number of scratches. Histopathological analysis demonstrated that Derma-Hc significantly inhibited epidermal hyperplasia, hyperkeratosis, and mast cells infiltration. In addition, the level of DSC1 was highly expressed in the epidermis by Derma-Hc. Moreover, mRNA expression level of FLG, an epidermal differentiation complex gene, was recovered by Derma-Hc treatment. KLK5 and KLK7 were markedly reduced to normalize keratinocyte differentiation in dorsal skin tissues and human keratinocytes. On the other hand, Derma-Hc restored expression level of SPINK5. In addition, Derma-Hc inhibited IL-22 via the blockade of JAK1-STAT3 signal pathway. Taken together, Derma-Hc, a natural herbal formula, regulated keratinocyte differentiation and inhibited epidermal hyperplasia with hyperkeratosis. Therefore, Derma-Hc could be a promising candidate for treating chronic AD through modulating signaling of IL-22-associated skin lichenification.

Abstract
In an emulsion-counter hybrid experiment performed at J-PARC, a Ξ^{-} absorption event was observed which decayed into twin single-Λ hypernuclei. Kinematic calculations enabled a unique identification of the reaction process as Ξ^{-}+^{14}N→_{Λ}^{10}Be+_{Λ}^{5}He. For the binding energy of the Ξ^{-} hyperon in the Ξ^{-}-^{14}N system a value of 1.27±0.21 MeV was deduced. The energy level of Ξ^{-} is likely a nuclear 1p state which indicates a weak ΞN-ΛΛ coupling.

Abstract
BACKGROUND The fruit of Zanthoxylum piperitum (ZP) is an herbal medicine as well as a spice agent in Asia to treat carminative, stomachic, anthelmintic and degenerative diseases. Z. piperitum was reported to have anti-oxidant, anti-inflammatory, anti-osteoarthritic and osteosarcoma proliferation-control effects. PURPOSE AND STUDY DESIGN This study was conducted to determine the anti-osteoporotic effects and mechanisms of action of ZP. METHODS Female ICR mice underwent ovariectomies (OVX) and were orally administered ZP at 1, 10 and 100 mg/kg for 6 weeks. The femoral and tibial bones were assessed by dual-energy X-ray absorptiometry and histology to analyze the bone mineral density (BMD) and the number of osteoclasts. Raw 264.7 cells were stimulated by 100 ng/ml receptor activator of nuclear factor-κB ligand (RANKL) for 7 days in the presence of ZP. RANKL-induced signaling molecules were analyzed in osteoclasts. RESULTS The levels of femoral and tibial BMD were significantly increased by ZP administration. Serum biomarkers such as osteocalcin, calcium, alkaline phosphatase and bone-specific alkaline phosphatase concentrations were markedly recovered to normal levels in ZP-treated osteoporotic mice. In addition, the number of osteoclasts in the head, trochanter and body of the femur was obviously decreased in the ZP treatment groups. Moreover, ZP treated-cells showed a reduction in the number of TRAP-positive multinuclear cells in RANKL-stimulated Raw 264.7 cells. ZP decreased the RANKL-activated NFATc1 and c-fos, transcription factors of osteoclast formation. The nuclear translocation of NF-κB and phosphorylation of ERK42/44 were inhibited by the ZP treatment in RANKL-induced osteoclasts. CONCLUSION Collectively, ZP exerts its inhibitory effect against bone resorption by regulating RANKL-mediated c-fos/NFATc1/NF-κB in osteoclast. ZP may prove to be a therapeutic agent for osteoporosis.

Abstract
Fine particulate matter (PM) exposure exhibits a crucial risk factor to exacerbate airway epithelial remodeling, fibrosis, and pulmonary destruction in asthma. Based on the use of essential oils from aromatic plants on pain relief and anti-inflammatory properties, we investigated the inhibitory effects of essential oil derived from the Mentha species (MEO) against asthma exposed to PM10. The MEO (0.1 v/v %) was aerosolized by a nebulizer to ovalbumin and PM10-induced asthmatic mice. Histological changes were confirmed in the lung tissues. To define the mode of action of the MEO on asthma, a protein–protein interaction network was constructed using menthol and menthone as the major components of the MEO. Cytokine expression and the JAK2/STAT3 signaling pathway were analyzed in lung epithelial A549 cells co-treated with MEO and PM10. Inhalation of MEO by nebulization inhibited respiratory epithelium hyperplasia, collagen deposition, and goblet cell activation in asthmatic mice. Through a network pharmacological analysis, cytokine–cytokine receptor interaction and JAK/STAT was expected to be underlying mechanisms of MEO on asthma. Treatment with MEO significantly reduced the IL-6 levels with a decrease in pro-inflammatory and T helper 2-specific cytokines. PM10-induced phosphorylation of JAK2 and STAT3 was significantly decreased by MEO. Collectively, MEO may have an inhibitory effect on asthma under the condition of PM10 exposure through the IL-6/JAK2/STAT3 signaling pathway.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Kyung-Bang Gumiganghwal-tang tablet (GMGHT) is a standardized Korean Medicine that could treat a cold, headache, arthralgia and fever. Although GMGHT has been used for arthritis-related diseases including a sprain, arthralgia, unspecified arthritis and knee arthritis, there is no pre-clinical evidence to treat osteoarthritis (OA). This study determined the drug dosage and the mechanisms of GMGHT for OA. METHODS OA was induced by intra-articular monoiodoacetic acid (MIA) injection in Sprague-Dawley rats. As calculated from the human equivalent dose formula, GMGHT was orally administered at the doses of 9.86, 98.6 and 986 mg/kg for 4 weeks. The arthritis score was performed by a blind test, and histological changes in articular cartilage were indicated by hematoxylin and eosin, Safranin O and toluidine blue staining. SW1353 chondrocytes were stimulated by interleukin (IL)-1β recombinant to analyze the expressions of Type II collagen, matrix metalloproteinases (MMPs) and nuclear factor (NF)-κB. RESULTS Rough and punctate surfaces of the femoral condyle induced by MIA, were recovered by the GMGHT treatment. The arthritis score was significantly improved in the 968 mg/kg of GMGHT-treated cartilage. Loss of chondrocytes and proteoglycan were ameliorated at the deep zone of the subchondral bone plate by the GMGHT administration in OA rats. The expression of Type II collagen was increased, while MMP-1, -3 and -13 levels were decreased in the GMGHT-treated SW1353 chondrocytes. In addition, the GMGHT treatment regulated NF-κB activation along with IL-6, transforming growth factor-β and IL-12 production. CONCLUSIONS GMGHT promoted the recovery of articular cartilage damage by inhibiting MMPs, accompanied with its anti-inflammatory effects in OA. GMGHT might be an alternative therapeutic treatment for OA.

Abstract
PURPOSE Periodontitis is characterised by inflammation of periodontium and alveolar bone loss. Gardenia jasminoides is reported to have anti-inflammatory effects. In this study, we investigated the effects of aqueous extract of G. jasminoides (GJ) on periodontitis. MATERIALS AND METHODS Male Sprague-Dawley rats aged 7 weeks were randomly placed in three groups (n = 7); non-ligatured and non-treated (NL group), ligatured and distilled water-treated (L group) and ligatured and 100 mg/kg GJ-treated (GJ group). After oral administration of GJ for 14 days, the mandibles were removed for histology. In addition, RAW 264.7 cells were treated with 100 ng/ml receptor activator of nuclear factor-κΒ ligand (RANKL) and 1, 10 and 100 μg/ml GJ for 7 days to analyse the expression of periodontitis-related factors. RESULTS In GJ-treated mice, the score of alveolar bone loss was statistically significantly attenuated compared with the L group. GJ treatment showed inhibition effect in the progress of cementum demineralisation. The expressions of proinflammatory cytokines in gingival tissue were statistically significantly regulated by GJ treatment. Additionally, GJ treatment showed the dose-dependent inhibition of RANKL-induced osteoclast formation. Furthermore, GJ treatment downregulated the RANKL-induced cytokine production in RAW 264.7 cells. CONCLUSION In summary, GJ ameliorated periodontitis-induced alveolar bone loss via inhibiting transcription factors including nuclear factor-κB, c-fos and extracellular signal-regulated kinase signalling. Therefore, GJ might be a therapeutic option for treating periodontitis.

Abstract
BACKGROUND Samsoeum (SSE), a Korean medicine, has been used to treat upper respiratory infection including residual coughs after catching a cold, and colds in patients with gastrointestinal disorder. In this study, we investigated the inhibitory effect of SSE against lipopolysaccharide (LPS)-induced bronchitis and characterized its optimal dosing range based on the improvement of SSE concentrations. MATERIALS AND METHODS Male Sprague Dawley rats were intra-nasally administered LPS on day 0, 3 and 6. 2 g kg-1 dose of SSE for rat was determined by the human equivalent dose formula and orally administered once a day from day 3 to day 6. To clarify the optimal administration dose of SSE, various doses including 0.5 (1/4 fold), 1 (1/2 fold), 6 (3 fold), 12 (6 fold), 24 (12 fold) and 36 g kg-1 (18 fold) were also orally administered. In addition, the molecular mechanism of SSE in mucin hyperproduction was investigated in LPS-sensitized A549 cells. RESULTS Oral administration of SSE ameliorated alveolar wall thickening and inflammatory cell infiltration of lung tissues in LPS-induced bronchitis at doses of 1/4 fold, 1/2 fold and 1 fold. The total cell and neutrophil numbers in bronchoalveolar lavage fluid (BALF) were reduced in the SSE-treated groups compared with the LPS group. In addition, 0.5, 1 and 2 g kg-1 of SSE suppressed LPS-induced mucin glycoprotein 5AC (MUC5AC) production in BALF. Furthermore, SSE treatment significantly inhibited the pro-inflammatory cytokines, resulting in the decrease of MUC5AC production by the JAK1/STAT6 signaling pathway. CONCLUSIONS 1, 2 and 6 g kg-1 of SSE ameliorated chronic bronchitis by inhibiting LPS-induced neutrophil infiltration and MUC5AC release in BALF. These findings suggested that SSE with 0.5-3-fold of general daily intake dose would be a therapeutic agent for chronic bronchitis.

Abstract
Background The human placenta (HP) is a complex organ used to alleviate tiredness and promote wound healing. Previous research showed the hair growth-promoting effect of HP. However, no reports have addressed the effects of HP on hair regrowth in chemotherapy-induced alopecia. In this study, we investigated the effects of HP on the apoptosis and proliferation of hair follicles in chemotherapy-induced alopecia. Methods Male C57BL/6 mice in telogen were depilated to enter anagen. After 9 days, dystrophic catagen was induced by the intraperitoneal injection of 150 mg/kg cyclophosphamide. During 9 to 16 days, 0.1 and 1 mg/mL HP were topically applied to depilated dorsal skin. Results Dystrophic hair follicles by cyclophosphamide were recovered by HP treatment. New hair shafts containing hair fibers appeared to be straight after HP treatment. Immunohistological staining revealed a significant increase of Ki67-positive cells in hair follicles treated with 1 mg/mL HP. Topical HP treatment increased the ratio of Bcl-2/Bax, while it attenuated the expression of pro-apoptotic Bax, p53, and cytochrome c with caspase-9 and -3. In addition, the expression of KGF and the phosphorylation of AKT were upregulated by HP treatment. Conclusion These results suggest that HP treatment induced hair growth by inhibiting apoptosis and promoting the proliferation of hair follicles. HP may be useful for treating chemotherapy-induced alopecia.

Abstract
Reactive oxygen species (ROS) act as signaling molecules to regulate various cell functions. Numerous studies have demonstrated ROS to be essential for the differentiation of adipocytes. Peroxiredoxins (Prxs) are a ubiquitous family of antioxidant enzymes in mammalian cells. Prx2 is present in the cytoplasm and cell membranes and demonstrates ROS scavenging activity. We focused on Prx2 involvement in regulating adipogenesis and lipid accumulation and demonstrated that Prx2 expression was upregulated during adipocyte differentiation. In addition, the silencing of Prx2 (shPrx2) inhibited adipogenesis by modulating adipogenic gene expression, and cell death was enhanced via increased ROS production in shPrx2-3T3-L1 cells. These results demonstrate that shPrx2 triggers adipocyte cell death and weakens adipocyte function via ROS production. Taken together, our data suggest the participation of Prx2 in adipocyte function and differentiation. Our results also imply that the downregulation of Prx2 activity could help prevent obesity. Overall, findings support the development of ROS-based therapeutic solutions for the treatment of obesity and obesity-related metabolic disorders.

Abstract
Allergic contact dermatitis (ACD) is characterized by itching, skin inflammation, and allergic responses caused by release of immunoglobulin E and T helper 2-specific cytokines. The aim of this study is to investigate the ameliorative and synergic effects of herbal formula, Derma-H, containing Astragalus membranaceus Fisch. ex Bunge (AM) and Nepeta tenuifolia Benth (NT) which have been used as traditional medicinal herbs for the cure of dryness, edema, and pruritus. 2,4-Dinitrochlorobenzene (DNCB) was applied for ACD induction. AM, NT, and a mixture of AM and NT was topically applied to skin lesions for 11 days. Dermatitis score and number of scratches were significantly diminished in AM, NT, and AM + NT (Derma-H)-treated groups. Especially, Derma-H was more effective than single treatment of AM and NT on skin hyperplasia and mast cell infiltration. Also, NGF expression decreased by NT and a mixture of AM and NT. Additionally, series of TrkA, Raf-1, MEK, and ERK were significantly inhibited by topical AM and NT application. Those findings suggested AM and NT treatment has a synergic effect on DNCB-induced ACD in mice.

Abstract
Transverse single-spin asymmetries of very forward neutral pions generated in polarized p+p collisions allow us to understand the production mechanism in terms of perturbative and nonperturbative strong interactions. During 2017, the RHICf Collaboration installed an electromagnetic calorimeter in the zero-degree region of the STAR detector at the Relativistic Heavy Ion Collider (RHIC) and measured neutral pions produced at pseudorapidity larger than 6 in polarized p+p collisions at sqrt[s]=510 GeV. The large nonzero asymmetries increasing both in longitudinal momentum fraction x_{F} and transverse momentum p_{T} have been observed at low transverse momentum p_{T}<1 GeV/c for the first time, at this collision energy. The asymmetries show an approximate x_{F} scaling in the p_{T} region where nonperturbative processes are expected to dominate. A non-negligible contribution from soft processes may be necessary to explain the nonzero neutral pion asymmetries.

Abstract
Soshiho-tang (SSHT) has traditionally been used to treat gastrointestinal disorders. In this experiment, we investigated the protective effect of SSHT on inflammatory liver injury in lipopolysaccharide (LPS)-sensitized mice. Male C57BL/6J mice aged 6 weeks were randomly placed in 6 groups (n = 5): normal mice (CTR), LPS-sensitized mice (LPS), LPS-sensitized mice treated with dexamethasone (DEX) and LPS-sensitized mice treated with 0.05, 0.55, and 5.55 g/kg of SSHT (SSHT 0.05, SSHT 0.55, and SSHT 5.55). Various doses of SSHT was given once a day for 7 days. After 2 h of LPS injection, the liver tissue was collected. SSHT pretreatment recovered hemorrhage of liver tissues in LPS-induced acute liver injury. The expressions of MAP Kinase, NF-κB, IκBα, p-IκBα, COX-2, and iNOS protein levels were markedly decreased by SSHT-treated liver tissues. Additionally, SSHT pretreatment significantly regulated the expressions of MCP-1, TNF-α, and IL-6 cytokines. These results suggest the potential of SSHT on the protection of acute liver injury.

Abstract
Exposure to particulate matter (PM) has been known to be one of the risk factors to cause allergic asthma, leading to development of respiratory disease. Banhahubak-tang tablet (BHT), a standardized Korean Medicine, is prescribed for neurasthenia, laryngopharyngitis and asthma. In this study, we investigated therapeutic effects of BHT on airway inflammation in ovalbumin (OVA) and PM smaller than 10 μm (PM10)-induced allergic asthma mice. To establish allergic asthma with airway hyper-responsiveness by PM10, BALB/c mice were sensitized and challenged with OVA and PM10, and orally administered BHT. Histological staining was performed to assess airway remodeling. Serum and bronchoalveolar lavage fluid (BALF) was collected for measuring immunoglobulin levels and counting inflammatory cells, respectively. Expression levels of Janus kinase 1 (JAK1)/signal transducer and activator of transcription 6 (STAT6), pro-inflammatory cytokines and type 2 T-helper (Th2)-related cytokines were analyzed in vivo and in vitro models. Histopathological analysis demonstrated that BHT suppressed inflammatory cell infiltration, mucus hypersecretion and collagen deposition in the airway. BHT administration effectively decreased number of inflammatory cells in BALF. BHT reduced total serum Immunoglobulin E (IgE) and Immunoglobulin G (IgG) levels. In addition, BHT significantly inhibited the phosphorylation of JAK1 and STAT6 expressions. Release of pro-inflammatory cytokines and Th2-related cytokines were down-regulated by BHT. In conclusion, BHT mitigated airway inflammation by down-regulating pro-inflammatory and Th2-related cytokines via JAK1/STAT6 signaling. BHT might be a promising herbal medicine for preventing airway inflammation. Moreover, an intervention study among humans is needed to further evaluate the possible beneficial effects of BHT in allergic asthma.

Abstract
High concentrations of glutamate induce neurotoxicity by eliciting reactive oxygen species (ROS) generation and intracellular Ca2+ influx. The disruption of Ca2+ homeostasis in the endoplasmic reticulum (ER) evokes ER stress, ultimately resulting in neuronal dysfunction. Additionally, glutamate participates in the development of neurodegenerative diseases, such as Alzheimer's and Parkinson's diseases. Peroxiredoxins (Prxs) are members of a family of antioxidant enzymes that protect cells from neurotoxic factor-induced apoptosis by scavenging hydrogen peroxide (H2O2). Prx4 is located in the ER and controls the redox condition within the ER. The present study investigated the protective effects of Prx4 against glutamate-induced neurotoxicity linked to ER stress. HT22 cells in which Prx4 was either overexpressed or silenced were used to elucidate the protective role of Prx4 against glutamate toxicity. The expression of Prx4 in HT22 cells was significantly increased in response to glutamate treatment, while ROS scavengers and ER chemical chaperones reduced Prx4 levels. Moreover, Prx4 overexpression reduces glutamate-induced apoptosis of HT22 cells by inhibiting ROS formation, Ca2+ influx, and ER stress. Therefore, we conclude that Prx4 has protective effects against glutamate-induced HT22 cell damage. Collectively, these results suggest that Prx4 could contribute to the treatment of neuronal disorders.

Abstract
AIM Preoperative factors predictive of permanent stoma creation were investigated in a long-term follow-up of patients with mid or low rectal cancer. METHOD We included patients who underwent radical resection for mid or low rectal cancer with available data for preoperative anal function measured by manometry and Faecal Incontinence Severity Index questionnaire between January 2005 and December 2015 in three tertiary referral hospitals. A permanent stoma was defined as a stoma present until the patient's last follow-up visit or death. Preoperative factors that predicted permanent stoma creation were analysed. RESULTS Over a median follow-up of 57.4 months (range 12-143 months), a permanent stoma was created in 144/577 (25.0%) patients, including 89 (15.4%) who underwent abdominoperineal resection, one (0.2%) who underwent Hartmann's operation without reversal, 15 (2.6%) with a diverting ileostomy at the time of initial sphincter-preserving surgery without undergoing stoma reversal, and 39 (6.8%) who underwent permanent ileostomy formation after sphincter-preserving surgery. Patients with permanent stoma creation had a shorter tumour distance from the anal verge (P < 0.001), larger tumour size (P = 0.020) and higher preoperative Faecal Incontinence Severity Index score (P = 0.020). On multivariable analysis, tumour distance from the anal verge predicted permanent stoma formation (relative risk 0.53 per centimetre increase; 95% confidence interval 0.46-0.60; P < 0.001) but preoperative anal function did not. CONCLUSION Tumour distance from the anal verge was the only preoperative determinant of permanent stoma creation in rectal cancer patients. These data may help mid and low rectal cancer patients understand the need for permanent stoma.

Abstract
Obesity was originally considered a disease endemic to developed countries but has since emerged as a global health problem. Obesity is characterized by abnormal or excessive lipid accumulation (World Health Organization, WHO) resulting from pre-adipocyte differentiation (adipogenesis). The endoplasmic reticulum (ER) produces proteins and cholesterol and shuttles these compounds to their target sites. Many studies have implicated ER stress, indicative of ER dysfunction, in adipogenesis. Reactive oxygen species (ROS) are also known to be involved in pre-adipocyte differentiation. Prx4 specific to the ER lumen exhibits ROS scavenging activity, and we thereby focused on ER-specific Prx4 in tracking changes in adipocyte differentiation and lipid accumulation. Overexpression of Prx4 reduced ER stress and suppressed lipid accumulation by regulating adipogenic gene expression during adipogenesis. Our results demonstrate that Prx4 inhibits ER stress, lowers ROS levels, and attenuates pre-adipocyte differentiation. These findings suggested enhancing the activity of Prx4 may be helpful in the treatment of obesity; the data also support the development of new therapeutic approaches to obesity and obesity-related metabolic disorders.

Abstract
Abstract
Background
Various bleeding risk scores have been proposed to assess the risk of bleeding in atrial fibrillation (AF) patients undergoing anticoagulation. PRECISE DAPT score has been developed to assess the out-of hospital bleeding risk in patients receiving dual antiplatelet therapy (DAPT). Our objective was to compare the predictive performance between the HAS-BLED (Hypertension, Abnormal Renal/Liver Function, Stroke, Bleeding History or Predisposition, Labile International Normalized Ratio, Elderly, Drugs/Alcohol), ATRIA (Anticoagulation and Risk Factors in Atrial Fibrillation), and PRECISE-DAPT (Predicting Bleeding Complication in Patients Undergoing Stent Implantation and Subsequent Dual Antiplatelet therapy) score in AF patients using antiplatelet agents or anticoagulants
Methods
We recruited 1,114 consecutive AF patients (51% male; median age, 71 years) receiving antiplatelet agents or oral anticoagulants from January 2014 through December 2018. Major bleeding was defined as according to the Bleeding Academic Research Consortium (BARC) criteria (type 3 or 5: hemodynamic instability, need for transfusion, drop in hemoglobin ≥3 g, and intracranial, intraocular or fatal bleeding). The performance of risk scores were assessed by C-statistic.
Results
Bleeding events occurred in 135 patients (12.1%) during 30 days, and 72 patients (6.5%) from 30 days till 1-year follow-up. Based on the C-statistic, PRECISE-DAPT score (AUC: 0.72, 95% CI: 0.69–0.75) had a good performance, significantly better than HAS-BLED (AUC: 0.64, 95% CI: 0.61–0.67) (p=0.008) or ATRIA scores (AUC: 0.57, 95% CI: 0.54–0.60) (p<0.001) for 30-days bleeding prediction. Also, PRECISE-DAPT score had a good C-statistic (AUC: 0.72, 95% CI: 0.69–0.75) for 1-year bleeding events compared with HAS-BLED (AUC: 0.64, 95% CI: 0.60–0.67) (p=0.02) or ATRIA (AUC: 0.61, 95% CI: 0.58–0.65) (p=0.01).
ROC curve for bleeding
Conclusions
The PRECISE-DAPT score has been used for assessing bleeding events during DAPT. Also, the PRECISE-DAPT score predicted bleedings better than HAS-BLED or ATRIA scores in AF patients. So, the PRECISE-DAPT score may be considered as bleeding risk score during DAPT or oral anticoagulation in clinical practice.

Abstract
Abstract
Background
Although older age is one of the most important risk factor for stroke in atrial fibrillation (AF), it is unclear whether oral anticoagulants are beneficial for AF patients with intermediate CHA2DS2-VASc score (1 for male or 2 for female) according to age threshold. We sought to investigate the effect of age-dependent antithrombotic therapy for ischemic stroke in Korean intermediate risk AF patients.
Methods
We enrolled 29,592 patients (males with CHA2DS2-VASc score of 1 and females with CHA2DS2-VASc score of 2) using the Korean National Health Insurance Service database. The clinical endpoint was the occurrence of ischemic stroke. The propensity score matching method was used to balance covariates across treated and untreated patients.
Results
Treated male AF patients were 6,570 (67.1%) with age <55 years, 7,115 (70.9%) with 55–64 years and 6,470 (68.3%) with 65–74 years in each age risk criterion. Also, treated female AF patients were 3,156 (71.3%) with age <55 years, 2,838 (71.0%) with 55–64 years and 3,440 (72.6%) with 65–74 years in each age risk criterion. Among male and female patients (age <55 years and 55–64 years) with 1 risk factor, an annual ischemic stroke rate was not significantly different between treated and untreated patients at full follow-up. However, treated AF patients who are in age 65–74 year without other risk factor had a much lower annual risk of ischemic stroke [(1.05%/year (male) and 1.04%/year (female)] compared with untreated patients [(1.77%/year (male) (p<0.026) and 1.86%/year (female) (p<0.041).
Conclusions
Age is an important predictor in determining the risk of ischemic stroke in AF patients with intermediate CHA2DS2-VASc scores (1 for male or 2 for female). We suggest that the benefit of anti-thrombotic therapy for intermediate risk AF patients depends on age threshold.

Abstract
Abstract
Background
Sex category (Sc, ie, female sex) confers 1 point on CHA2DS2-VASc score. So, no woman with atrial fibrillation (AF) can have a CHA2DS2-VASc score of 0. This study aimed to compare CHA2DS2-VA (excluding female sex) and CHA2DS2-VASc score in Korean AF patients.
Methods
Using the Korean National Health Insurance Service database, we analyzed the risk of ischemic stroke in non-valvular AF patients between 2013 and 2017. The predictive value of the CHA2DS2-VA and CHA2DS2-VASc scores for ischemic stroke was evaluated by c-statistic difference and net reclassification improvement (NRI). The propensity score matching method was used to balance covariates across male and female AF patients.
Results
A total of 182,133 patients with AF (49.2% women) were included to this study. The adjusted incidence rate (IR) of ischemic stroke was not significantly different between males and females (0.89%/y and 0.90%/y, respectively, p=0.411) in low-risk patients without risk factor. Also, no sex difference was found in high-risk patients with above 2 risk factors for ischemic stroke (4.46%/y for male and 4.49%/y for male, p=0.498). In c-statistic analysis for ischemic stroke, there was no significant difference between the CHA2DS2-VA and CHA2DS2-VASc scores (AUC 0.662 vs. 0.664, z=1.572, p=0.116). When compared with CHA2DS2-VASc score, CHA2DS2-VA score was not significantly inferior in net reclassification improvement (NRI 0.031, 95% CI 0.002–0.037, p=0.118) for ischemic stroke.
C-statistics
Conclusions
In Korean AF patients, the CHA2DS2-VA score excluding female sex is a useful risk scoring system for ischemic stroke.

Abstract
AIM This study aimed to investigate the association between Twitter exposure and the number of citations for coloproctology articles. METHOD Original articles from journals using Twitter between June 2015 and May 2016 were evaluated for the following characteristics: publishing journal; article subject; study design; nationality, speciality and affiliation of the author(s); and reference on Twitter. Citation data for these articles were retrieved from Google Scholar (https://scholar.google.com) in January 2018. We performed a univariate analysis using these data followed by a multivariate, logistic regression analysis to search for factors associated with a high citation level, which was defined as accrual of more than five citations. RESULTS Out of six coloproctology journals listed on the InCites JCR database, three (Diseases of the Colon & Rectum, Colorectal Disease and Techniques in Coloproctology) used Twitter, where 200 (49.5%) out of a total of 404 articles had been featured. Citation rates of articles that featured on Twitter were significantly higher than those that did not (11.4 ± 9.2 vs 4.1 ± 3.1, P < 0.001). In multivariate analysis, Twitter exposure (OR 8.6, P = 0.001), European Union nationality (OR 2.4, P = 0.004), Colorectal Disease journal (OR 3.3, P = 0.005) and systematic review articles (OR 3.4, P = 0.009) were associated with higher citation levels. CONCLUSION Article exposure on Twitter was strongly associated with a high citation level. Medical communities should encourage journals as well as physicians to actively utilize social media to expedite the spread of new ideas and ultimately benefit medical society as a whole.

Abstract
Setting Nineteen health facilities in rural, southeastern Malawi. Objective To describe the implementation and results of a 6-week intervention to accelerate human immunodeficiency virus (HIV) case finding. Design Six HIV testing strategies were simultaneously implemented. Routinely collected data from Ministry of Health registers were used to determine the number of HIV tests performed and of new cases identified. The weekly averages of the total number of tests and new cases before and during the intervention were compared. Testing by age group and sex was described. The percentage yield of new cases was compared by testing strategy. Results Of 29 703 HIV tests conducted, 1106 (3.7%) were positive. Of the total number of persons tested, 69.5% were women and 75.5% were aged >15 years. The yield of positive test results was 3.5% among women, 4.3% among men, 4.4% among those aged >15 years and 1.5% among those aged ⩽15 years. The average weekly number of tests increased 106.7% from 3337 to 6896 (P = 0.002). The average weekly number of positive cases identified increased 51.9% from 158 to 240 (P = 0.017). The testing strategy with the highest yield resulted in a 6.0% yield; the lowest was 1.3%. The yield for all strategies, except one, was highest in adult men. Conclusion A multi-strategy approach to HIV testing and counseling can be an effective means of accelerating HIV case finding.

Abstract
Both direct- and evanescent-field interactions with carbon nanotubes (CNTs) are applied to achieve stable Q-switched operation of Yb:KYW planar waveguide lasers. The performance characteristics were investigated in a same cavity configuration and analyzed in detail in the following three cases, CNTs deposited onto end mirror (M-coating), output coupler (OC-coating) and top surface of the planar waveguide (WG-coating). Maximum output powers, repetition rates, and minimum pulse durations are 61 mW, 1103 kHz and 215 ns for OC-coating, 39 mW, 1052 kHz and 275 ns for WG-coating, and 26 mW, 1119 kHz and 217 ns for M-coating, respectively. From the calculation of the configuration-dependent stability range, the beam size and the electric field distribution in the Yb:KYW planar waveguide, it is confirmed that the evanescent-field interaction scheme makes stable Q-switching possible with much lower intensities at saturable absorber compared to the direct-field interaction scheme in the presented waveguide laser operation.

Abstract
Asymmetric nuclear collisions of p+Al, p+Au, d+Au, and ^{3}He+Au at sqrt[s_{NN}]=200 GeV provide an excellent laboratory for understanding particle production, as well as exploring interactions among these particles after their initial creation in the collision. We present measurements of charged hadron production dN_{ch}/dη in all such collision systems over a broad pseudorapidity range and as a function of collision multiplicity. A simple wounded quark model is remarkably successful at describing the full data set. We also measure the elliptic flow v_{2} over a similarly broad pseudorapidity range. These measurements provide key constraints on models of particle emission and their translation into flow.

Abstract
Phlomis umbrosa Turcz (labiatae) has been suggested to promote bone growth. However, the anti-osteoporotic effects of P. umbrosa have not yet been elucidated. In the present study, the osteogenic effects of P. umbrosa were investigated in an osteoporosis model. ICR female mice were ovariectomized (OVX) to induce osteoporosis for 7 weeks. Treatment with 1, 10 and 100 mg/kg P. umbrosa was administrated orally to the OVX mice for 6 weeks. At the end of experiment, the microstructure of the capital femoral epiphysis was investigated. The levels of bone mineral density (BMD), bone mineral content (BMC) and serum osteocalcin concentration were evaluated. In addition, mineralized Saos-2 osteoblast cells were treated with 0.01, 0.1 and 1 µg/ml P. umbrosa to analyze the expression of osteoblast differentiation-associated factors. Hyperplasia of the growth plate in the femur was recovered by P. umbrosa treatment. BMD and BMC were significantly increased in P. umbrosa-treated femurs. Serum calcium concentration was increased following P. umbrosa treatment. In addition, the ratio of mineralization was markedly increased in P. umbrosa-treated differentiated osteoblasts along with increases in Runx2 levels. P. umbrosa conferred its osteogenic effects by upregulating Runx2 in osteoporosis. P. umbrosa may be a potential therapeutic material for the treatment of osteoporosis.

Abstract
Background Schisandra chinenesis (SC) has been reported to have ameliorative effect on osteoporosis. However, the mechanisms underlying the anti-osteoporosis activity of SC have not been clearly elucidated. In the present study, we determined the effects of SC on The receptor activator of NF-kB ligand (RANKL)-induced osteoclastogenesis and its potential mechanism. Methods Raw 264.7 cells were treated with 0.6, 6 and 60 μg/mL SC in the presence of 100 ng/mL RANKL for 7 days. RANKL-induced osteoclast formation was analyzed by tartrate resistant acid phosphatase (TRAP) staining. The osteoclast differentiation-related factors were confirmed along with TNF-α. Results SC inhibits the RANKL-induced osteoclast differentiation in dose-dependent manner within non-toxic concentrations. The supernatant concentrations of TNF-α were significantly decreased by SC treatment. In addition, osteoclastogenesis-related factors, TRAP6 and NF-κB, were markedly decreased by SC in RANKL-induced osteoclasts. Mechanistically, SC reduced the RANKL-triggered NFATc1 and c-fos expressions. Conclusions Taken together, our data suggest that SC can modulate bone metabolism by suppressing RANKL-induced osteoclast differentiation.

Abstract
Anemarrhena asphodeloides Bunge has been traditionally used in Korean medicine for its antipyretic, diuretic, sedative, and antitussive effects. In the present study, the effects of an ethanol extract of A. asphodeloides Bunge (AAB) on osteoporosis and its underlying mechanisms on bone remodeling were investigated. Osteoporosis was induced in ICR strain mice by ovariectomy. The mice were divided into four groups: sham, ovariectomized, 17β‑estradiol and 100 mg/kg AAB. The treatment was continued for 4 weeks. Bone mineral density (BMD) and bone mineral content (BMC) were measured using dual‑energy X‑ray absorptiometry. In addition, Raw 264.7 cells were treated in the presence of 0.1, 1 and 10 µg/ml AAB with 100 ng/ml receptor activator of nuclear factor κΒ ligand (RANKL) to induce osteoclast formation and stained with tartrate resistant acid phosphatase. In addition, levels of osteoclast‑related factors were analyzed to investigate the signaling cascades in osteoclasts. The results demonstrated that AAB treatment reversed the decreases of both BMD and BMC in osteoporotic femurs. Additionally, the formation of osteoclasts was significantly suppressed by the AAB treatment in RANKL‑stimulated Raw 264.7 cells. Compared with cells treated with RANKL alone, the AAB‑treated osteoclasts had significantly decreased tumor necrosis factor‑α and interleukin‑6. The protein levels of c‑fos were also decreased in the AAB‑treated osteoclasts. Furthermore, the RANKL‑induced nuclear translocation of nuclear factor‑κB was attenuated in osteoclasts by the AAB treatment compared with cells treated with RANKL alone. Finally, AAB treatment downregulated the phosphorylation of mitogen‑activated protein kinases. The present results demonstrated that AAB exhibited ameliorative effects on osteoporosis by inhibiting osteoclastogenesis, and suggested that AAB may be a potential candidate for the treatment of osteoporosis.
