RESUMO
OBJECTIVE: Alcohol intake is a major risk factor for various diseases. Elucidating alcohol use disorder (AUD) is important in preventing diseases and promoting health. We aimed to investigate the effect of art therapy on emotional (Minnesota Multiphasic Personality Inventory-2 [MMPI-2]) and physical (natural killer [NK] cell count, expression of stress-associated proteins [SAP], and electroencephalography) changes in patients with AUD. METHODS: Participants were randomly divided into two groups (n = 35), with the experimental group undergoing art therapy involving weekly 60-min group therapy sessions for 10 weeks. Statistical analysis was performed using Ranked ANCOVA and Wilcoxon's signed rank test. Western blotting was performed to analyze serum SAP levels. RESULTS: We observed an association between psychological mechanisms and stress proteins. There was an increased number of NK cells in the experimental group after the program. Moreover, compared with the control group, the experimental group showed significant changes in SAP expression. Further, the experimental group showed a positive change in the MMPI-2 profile, as well as a decrease in depression, anxiety, impulsivity, and alcohol dependence. CONCLUSIONS: Continuous psychological support could be applied as a stress-control program for preventing stress recurrence and post-discharge relapse. Our findings strengthen the link between biomedical science and mental health in rehabilitation treatment for AUD.

BACKGROUND: The enhancement of energy expenditure has attracted attention as a therapeutic target for the management of body weight. Withaferin A (WFA), a major constituent of Withania somnifera extract, has been reported to possess anti-obesity properties, however the underlying mechanism remains unknown. PURPOSE: To investigate whether WFA exerts anti-obesity effects via increased energy expenditure, and if so, to characterize the underlying pathway. METHODS: C57BL/6 J mice were fed a high-fat diet (HFD) for 10 weeks, and WFA was orally administered for 7 days. The oxygen consumption rate of mice was measured at 9 weeks using an OxyletPro™ system. Hematoxylin and eosin (H&E), immunohistochemistry, immunoblotting, and real-time PCR methods were used. RESULTS: Treatment with WFA ameliorated HFD-induced obesity by increasing energy expenditure by improving of mitochondrial activity in brown adipose tissue (BAT) and promotion of subcutaneous white adipose tissue (scWAT) browning via increasing uncoupling protein 1 levels. WFA administration also significantly increased AMP-activated protein kinase (AMPK) phosphorylation in the BAT of obese mice. Additionally, WFA activated mitogen-activated protein kinase (MAPK) signaling, including p38/extracellular signal-regulated kinase MAPK, in both BAT and scWAT. CONCLUSION: WFA enhances energy expenditure and ameliorates obesity via the induction of AMPK and activating p38/extracellular signal-regulated kinase MAPK, which triggers mitochondrial biogenesis and browning-related gene expression.

Patrinia scabiosaefolia (PS) and Hippophae rhamnoides (HR) are traditionally used functional foods. Extracts from the root of PS are known for their anti-inflammatory effects, whereas those from the leaf of HR are effective at both preventing and treating obesity. This study investigated whether the extract combination of PS and HR (PHE) affected weight loss in obese mice. In vitro experiments demonstrated that PHE showed a synergistic effect on inhibiting adipocyte differentiation as compared with treatment with the single extracts. Additionally, PHE suppressed adipogenic-related genes in a concentration-dependent manner. In vivo PHE supplementation suppressed body weight gain, inhibited hepatic lipid accumulation, decreased adipose size, serum triglycerides, and improved insulin resistance in obese mice. These results suggest that a treatment strategy using a combination of plant-derived extracts might be effective at ameliorating obesity. PRACTICAL APPLICATIONS: Currently, common methods for reducing obesity are diet and exercise. These can stimulate oxidative phosphorylation and metabolic activation so have significantly effects. However, these are largely due to individual compliance; there is no significant effect of reducing the worldwide obesity rate. Recently, herbal extracts has been reported as alternative medicine about inflammatory and obesity because diet with the herbal extracts can improve obesity with minimal side effects. Of particular, a mixture of herbal products was investigated for the treatment of obesity. Our reports demonstrated the synergistic effects of natural products and emphasizes the need for studies investigating other combinations of herbal extracts in the treatment of obesity. The results of our studies highlight the synergistic effects of combination phytochemical extracts and their role in ameliorating obesity.

Withania somnifera (WS), commonly known as ashwagandha, possesses diverse biological functions. WS root has mainly been used as an herbal medicine to treat anxiety and was recently reported to have an anti-obesity effect, however, the mechanisms underlying its action remain to be explored. We hypothesized that WS exerts its anti-obesity effect by enhancing energy expenditure through improving the mitochondrial function of brown/beige adipocytes and skeletal muscle. Male C57BL/6J mice were fed a high-fat diet (HFD) containing 0.25% or 0.5% WS 70% ethanol extract (WSE) for 10 weeks. WSE (0.5%) supplementation significantly suppressed the increases in body weight and serum lipids, and lipid accumulation in the liver and adipose tissue induced by HFD. WSE supplementation increased oxygen consumption and enhanced mitochondrial activity in brown fat and skeletal muscle in the HFD-fed mice. In addition, it promoted browning of subcutaneous fat by increasing mitochondrial uncoupling protein 1 (UCP1) expression. Withaferin A (WFA), a major compound of WS, enhanced the differentiation of pre-adipocytes into beige adipocytes and oxygen consumption in C2C12 murine myoblasts. These results suggest that WSE ameliorates diet-induced obesity by enhancing energy expenditure via promoting mitochondrial function in adipose tissue and skeletal muscle, and WFA is a key regulator in this function.

BACKGROUND: The roots of Partrinia scabra have been used as a medicinal herb in Asia. We previously reported that the inhibitory effect of patriscabrin F on lipopolysaccharide (LPS)-induced nitric oxide (NO) production was the most potent than that of other isolated iridoids from the roots of P. scabra. PURPOSE: We investigated the anti-inflammatory activity of patriscabrin F as an active compound of P. scabra and related signaling cascade in LPS-activated macrophages. METHOD: The anti-inflammatory activities of patriscabrin F were determined according to its inhibitory effects on NO, prostaglandin E2 (PGE2), and pro-inflammatory cytokines. The molecular mechanisms were revealed by analyzing nuclear factor-κB (NF-κB), activator protein-1 (AP-1), interferon regulatory factor 3 (IRF3), and Janus kinase (JAK)/signal transducer and activator of transcription (STAT) pathway. RESULTS: Patriscabrin F inhibited the LPS-induced production of NO, PGE2, tumor necrosis factor-α (TNF-α), interleukin (IL)-1ß, and IL-6 in both bone-marrow derived macrophages (BMDMs) and RAW 264.7 macrophages. Patriscabrin F downregulated LPS-induced inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2), TNF-α, IL-1ß, and IL-6 at the transcriptional level. Patriscabrin F suppressed LPS-induced NF-κB activation by decreasing p65 nuclear translocation, inhibitory κBα (IκBα) phosphorylation, and IκB kinase (IKK)α/ß phosphorylation. Patriscabrin F attenuated LPS-induced AP-1 activity by inhibiting c-Fos phosphorylation. Patriscabrin F suppressed the LPS-induced phosphorylation of IRF3, JAK1/JAK2, and STAT1/STAT3. CONCLUSION: Taken together, our findings suggest patriscabrin F may exhibit anti-inflammatory properties via the inhibition of NF-κB, AP-1, IRF3, and JAK-STAT activation in LPS-induced macrophages.

Nonalcoholic fatty liver disease (NAFLD) is a common risk factor for metabolic syndrome that increases the risk of future cardiovascular disease, stroke, and diabetes. Recently, autophagy has been proposed as a means to prevent NAFLD. We investigated whether substances with autophagy-inducing activity alleviate NAFLD. The Valeriana fauriei (V. fauriei) was selected as a potential autophagy inducer among various natural materials using a Cyto-ID autophagy detection kit. V. fauriei 70 % ethanol extract (VFE) increased LC3II levels in the presence of the lysosomal inhibitor and reduced the GFP/mCherry puncta ratio, suggesting that VFE enhanced autophagy. VFE reduced oleic acid (OA)-induced lipid accumulation and increased the number of autophagosome in hepatocytes. Autophagy induction by VFE is due to inhibition of mTORC1 activity. VFE supplementation reduced fatty liver by downregulating lipogenesis-related genes and increased the autophagy, as revealed by TEM and IHC analysis in the fatty liver. We identified iridoids as main compounds of VFE; didrovaltrate (DI), valeriotriate B (VAL B), valeriotetrate C (VAL C), valtrate (VAL), and valechlorine (VC) were shown to enhance autophagy. These compounds also reduced OA-induced lipid accumulation in an Atg5-dependent manner. Taken together, VFE and its iridoids might be effective in alleviating fatty liver by acting as autophagy enhancers to break down LDs.

In type 2 diabetes (T2D), insufficient secretion of insulin from the pancreatic ß-cells contributes to high blood glucose levels, associated with metabolic dysregulation. Interest in natural products to complement or replace existing antidiabetic medications has increased. In this study, we examined the effect of Astragalus membranaceus extract (ASME) and its compounds 1-9 on glucose-stimulated insulin secretion (GSIS) from pancreatic ß-cells. ASME and compounds 1-9 isolated from A. membranaceus stimulated insulin secretion in INS-1 cells without inducing cytotoxicity. A further experiment showed that compounds 2, 3, and 5 enhanced the phosphorylation of total insulin receptor substrate-2 (IRS-2), phosphatidylinositol 3-kinase (PI3K), and Akt, and activated pancreatic and duodenal homeobox-1 (PDX-1) and peroxisome proliferator-activated receptor-γ (PPAR-γ), which are associated with ß-cell function and insulin secretion. The data suggest that two isoflavonoids (2 and 3) and a nucleoside (compound 5), isolated from the roots of A. membranaceus, have the potential to improve insulin secretion in ß-cells, representing the first step towards the development of potent antidiabetic drugs.

Inula japonica Thunb. (Asteraceae) is a flowering plant that grows mainly in Korea, Japan, and China and its flower extract has diverse biological effects such as anti-inflammatory and antioxidative activities. However, the effects on obesity and enhancement of endurance capacity have not been explored yet. This study aims to reveal the effects of I. japonica flower ethanol extract (IJE) on obesity and endurance capacity in high-fat diet (HFD) fed C57BL/6J mice and the mechanism. IJE inhibited lipid accumulation in 3T3-L1 adipocytes in vitro. Also, IJE-fed mice showed reduced body weight gain, hepatic lipid, and body fat mass, and increased muscle weight. IJE reduced lipid accumulation in the liver and adipose tissue by decreasing lipogenic and adipogenic gene expression. Additionally, consumption of low-dose IJE significantly enhanced endurance capacity via increasing AMP-activated protein kinase activity and mRNA levels of Myh7 and Myh2. Luteolin and 1ß-hydroxyalantolactone (1ß-HA), compounds of IJE, are involved in anti-adipogenesis in the 3T3-L cells and only luteolin increased the protein levels of MHC during C2C12 myoblast differentiation. Collectively, our results suggest that consumption of IJE not only helps to prevent obesity but also enhances endurance capacity reduced by HFD.

Although classification of an individual's Sasang constitution is a key step in the prescription of traditional Korean medicine, the classifying process is complex and not objective. Identification of metabolic-based biomarkers could allow the development of a reliable and sensitive classification technique and even therapeutic management. Our pilot study investigated whether metabolites in plasma are characteristic of Sasang constitutions. Ultra-high-performance liquid chromatography-quadrupole time-of-flight mass spectrometry-based metabolic analysis was conducted against 15 Soyangin (SY), 15 Taeeumin (TE), and 18 Soeumin (SE) individuals, as classified according to the Questionnaire for Sasang Constitution Classification II (QSCC II) and specialist diagnosis. Metabolomics data showed that the TE group was significantly separated from the SY and SE groups. Nine canonical pathways related to constitution; phenylalanine metabolism, aminoacyl-tRNA, tyrosine, and tryptophan biosynthesis were activated in the TE group as compared with the other groups. Similar to the results of the metabolomics analysis, the TE group was also significantly separated from the other two groups by lipidomic analysis. On the other hand, the intensity of lipid metabolites was higher in the SY group than in the other groups. Our findings suggest that the combined analysis of metabolomics and lipidomics can provide useful information for characteristics of Sasang constitutions.
RESUMO
Pectolinarin and pectolinarigenin have been reported to be major compounds in Cirsium setidens. In the present study, we demonstrated inhibitory effects of pectolinarin and pectolinarigenin from C. setidens on melanogenesis. Melanin synthesis was decreased in both pectolinarin- and pectolinarigenin-treated melan-a cells and in a reconstructed human skin model. However, pectolinarigenin treatment showed more potent inhibitory activity of melanin synthesis than did pectolinarin treatment. The concentrations of pectolinarin and pectolinarigenin in C. setidens water extracts were determined by HPLC. Unfortunately, the amount of pectolinarigenin of C. setidens water extract was lower than that of pectolinarin. To increase the pectolinarigenin content in C. setidens water extract, several component conversion methods were studied. Consequently, we identified that microwave irradiation under 1% acetic acid was an optimum sugar elimination method.

SCOPE: Yuja (Citrus junos Tanaka) possesses various health benefits, but its effects on bone health are unknown. In this study, the preventative effects of yuja peel ethanol extract (YPEE) on osteopenia were determined in ovariectomized (OVX) rats, and the mechanisms by which YPEE and its flavanones regulate osteoblastogenesis were examined in vitro. METHODS AND RESULTS: The effects of YPEE on osteoblastogenesis were investigated in MC3T3-E1 cells. YPEE promoted alkaline phosphatase (ALP) activity, mineralization, and the expression of osteoblast differentiation marker genes, such as ALP, runt-related transcription factor 2 (Runx2), and osteocalcin. YPEE and its flavanones promoted osteoblast differentiation via BMP-2-mediated p38 and the Smad1/5/8 signaling pathway. YPEE supplementation significantly decreased body weight and increased uterine weight and bone mineral density in OVX rats. Based on a micro-CT analysis of femurs, YPEE significantly attenuated osteopenia and increased trabecular volume fraction, trabecular separation, and trabecular number (p < 0.05). CONCLUSION: Dietary YPEE has a protective effect on OVX-induced osteopenia. YPEE and its flavanones promote osteoblastogenesis via the activation of the BMP/p38/Smad/Runx2 pathways. These results extend our knowledge of the beneficial effects of YPEE and provide a basis for the development of novel therapies for osteoporosis.
