Background Associations between hyperuricemia, cardiovascular diseases and diabetes have been reported, but few of the studies have been conducted in the Korean population. The present study examined a Korean adult population with respect to the relationships between serum uric acid concentrations and hypertension, insulin resistance, and the risk factors of metabolic syndrome. Methods and Results A total of 53,477 subjects were divided into 4 groups according to serum uric acid quartiles. The incidence of hypertension in all subjects was higher in the first quartile than in the third plus fourth quartile (odds ratio (OR) 1.192, p<0.001). Homeostasis model assessment index was found to be associated with serum uric acid concentration in all subjects (OR 1.193, p<0.001), and the serum uric acid concentration was positively correlated with the risk factors of metabolic syndrome. In addition, the number of metabolic syndrome variables increased as serum uric acid concentration increased. Conclusions Serum uric acid concentration was found to be independently correlated with hypertension, insulin resistance and the risk factors of metabolic syndrome. In addition, even those with a serum uric acid concentration in the normal range showed an increased risk of metabolic syndrome as serum uric acid concentration increased.

[Purpose] This study aimed to investigate the effect of neuromuscular electrical stimulation (NMES) on lip strength and closure function of patients with dysphagia after stroke. [Subjects and Methods] Eight patients with dysphagia were recruited. NMES was applied to the orbicularis oris muscle. All the participants received NMES for 30 min/d, 5 d/wk, for 4 weeks. Lip strength was measured using the Iowa Oral Performance Instrument. To assess lip closure, the lip closure subitem of the videofluoroscopic dysphagia scale was used. [Results] Lip strength showed significant improvement and lip closure function showed a significant decrease. [Conclusion] This study demonstrates that NMES is useful for improving lip strength and closure function.

[Purpose] This study was conducted to investigate the effect of exercise training using transcranial direct current stimulation (tDCS) on breathing in patients with chronic stroke patients. [Subjects and Methods] Thirty chronic stroke patients who do not show abnormal response to electric stimulation were enrolled in this study and each 15 subjects were randomized either into the study group and the sham-controlled group. The subjects performed diaphragmatic breathing exercise for 20 minutes while tDCS device was attached to them (for study group, the device was on while for the sham-controlled group, the device was turned off 30 seconds later) [Results] The results of FVC, FEF1 and FEV1/FVC in the study group and those of FVC and FEV1 in the sham-controlled group were significantly increased after the breathing exercise. The independent comparison result between the groups showed that the breathing performance of study group significantly improved based on the results of FVC and FEV1. [Conclusion] In conclusion, the results of this study confirmed that breathing exercise effectively improved FVC and FEV1 in chronic stroke patients. Also, the breathing exercise using tDCS was more effective in improving FVC and FEV1.

Background:There has been debate regarding the added benefit of high-intensity statins compared with low-moderate-intensity statins, especially in patients with acute myocardial infarction (AMI).Methods and Results:The Korea Acute Myocardial Infarction Registry-National Institutes of Health consecutively enrolled 13,104 AMI patients. Of these, a total of 12,182 patients, who completed 1-year follow-up, were included in this study, and all patients were classified into 3 groups (no statin; low-moderate-intensity statin; and high-intensity statin). The primary outcome was major adverse cardiac event (MACE) including cardiac death, non-fatal MI, and repeat revascularization at 1 year. Both low-moderate-intensity and high-intensity statin significantly reduced low-density lipoprotein cholesterol (LDL-C; all P<0.001). Compared with the no statin group, both statin groups had significantly lower risk of MACE (low-moderate intensity: HR, 0.506; 95% CI: 0.413–0.619, P<0.001; high intensity: HR, 0.464; 95% CI: 0.352–0.611, P<0.001). The risk of MACE, however, was similar between the low-moderate- and high-intensity statin groups (HR, 0.917; 95% CI: 0.760–1.107, P=0.368). Multivariable adjustment, propensity score matching, and inverse probability weighted analysis also produced the same results.Conclusions:When adequate LDL-C level is achieved, patients on a low-moderate-intensity statin dose have similar cardiovascular outcomes to those on high-intensity statins.

To assess the growth and flowering of the Doritaenopsis orchid in alternative substrates, Doritaenopsis Queen Beer ‘Mantefon’ was grown for 15 months in four different substrates; a commercial 100% Chilean sphagnum moss (S), peat moss (P), medium-grade Douglas fir bark mixed with P with a 3:7 ratio (v/v) (BP), and S and P mixes (SP) with a 4:6 ratio (v/v). Physical (porosity and water holding capacity) and chemical (pH and EC) properties of the four substrates were investigated. SP substrate had significantly higher substrate volumetric water content (VWC) than the other three substrates only for the first 3 days after fertigation, and only the BP substrate maintained lower air space than the other substrates. Although there was no relevant growth responses to VWC and air space changes, a better growth in shoots and fastened flowering of Doritaenopsis ‘Mantefon’ occurred in plants grown in the P substrate, which could be attributed to providing better contact of terrestrial roots to the substrate enabling enough water and nutrient supply, along with a proper pH range of 6.15. At 15 months after transplanting, plants grown in the P and BP substrates had larger leaves and a greater shoot dry weight than the plants grown in the S and SP substrates. Plants grown in the P substrate produced 2.75 flower spikes, whereas the plants grown in the S, BP, and SP substrates produced 2.00 to 2.33 flower spikes. Plants grown in the P, BP, S, and SP substrates produced a third flower spike, being 67%, 33%, 17%, and 8%, respectively. There was no significant difference in the total number of flowers, while the total numbers of buds were 32.3, 23.4, 23.0, and 19.7 in plants grown in the P, S, BP, and SP substrates, respectively. Time to visible flower spike was shortened in plants grown in the P substrate compared to the plants grown in other substrates. With these results, using alternative substrates including peat moss for Doritaenopsis cultivation, growers may be able to promote leaf growth and flower spike induction with lower expenses on substrate costs, resulting in a high quality production of Doritaenopsis ‘Mantefon’ with more profit.

Fatalities among avian species due to multiple bee stings are rare. Sixteen pigeons on a farm in Bangladesh each suffered multiple bee stings. Ten of the pigeons died before treatment, 5 (4–11 stings) died within 12 hr after treatment, and 1 pigeon (only 3 stings) survived. Body temperature, heart rate, respiratory rate, hematocrit, hemoglobin, erythrocytes, thrombocytes, MCV, MCH and MCHC decreased significantly after the incident, but leucocytes, heterophils, basophils, eosinophils, monocytes, ALT, AST, LDH, CK, creatinine, BUN and UA increased markedly. Overall, the hematological and biochemical changes in the bee-stung pigeons were similar to those of mammals; however, avian species may be more sensitive to bee stings than mammals.

Gut bacteria might contribute in early stage of colorectal cancer through the development and advancement of colon adenoma, by which exploring either beneficial bacteria, which are decreased in formation or advancement of colon adenoma and harmful bacteria, which are increased in advancement of colon adenoma may result in implementation of dietary interventions or probiotic therapies to functional means for prevention. Korean fermented kimchi is one of representative probiotic food providing beneficiary microbiota and exerting significant inhibitory outcomes in both APC/Min+ polyposis model and colitis-associated cancer. Based on these backgrounds, we performed clinical trial to document the changes of fecal microbiota in 32 volunteers with normal colon, simple adenoma, and advanced colon adenoma with 10 weeks of fermented kimchi intake. Each amplicon is sequenced on MiSeq of Illumina and the sequence reads were clustered into Operational Taxonomic Units using VSEARCH and the Chao Indices, an estimator of richness of taxa per individual, were estimated to measure the diversity of each sample. Though significant difference in α or β diversity was not seen between three groups, kimchi intake significantly led to significant diversity of fecal microbiome. After genus analysis, Acinobacteria, Cyanobacteria, Clostridium sensu, Turicibacter, Gastronaeophillales, H. pittma were proven to be increased in patients with advanced colon adenoma, whereas Enterococcua Roseburia, Coryobacteriaceau, Bifidobacterium spp., and Akkermansia were proven to be significantly decreased in feces from patients with advanced colon adenoma after kimchi intake. Conclusively, fermented kimchi plentiful of beneficiary microbiota can afford significant inhibition of either formation or advancement of colon adenoma.

To better understanding Brucella abortus infection, serum metabolites of B. abortus -infected and -uninfected mice were analyzed and twenty-one metabolites were tentatively identified at 3 and 14 days post-infection (d.p.i.). Level of most lysophosphatidylcholines (LPCs) was found to increase in infected mice at 3 d.p.i., while it was decreased at 14 d.p.i. as compared to uninfected mice. In contrast, acylcarnitines were initially reduced at 3 d.p.i then elevated after two-weeks of infection, while hydroxysanthine was increased at 14 d.p.i. in infected mice. Our findings suggest that the significant changes in LPCs and other identified metabolites may serve as potential biomarkers in acute phase of B. abortus infection.

Human respiratory syncytial virus (hRSV) is the most common cause of bronchiolitis and pneumonia in infants. The lack of proper prophylactics and therapeutics for controlling hRSV infection has been of great concern worldwide. Xylitol is a well-known sugar substitute and its effect against bacteria in the oral cavity is well known. However, little is known of its effect on viral infections. In this study, the effect of dietary xylitol on hRSV infection was investigated in a mouse model for the first time. Mice received xylitol for 14 d prior to virus challenge and for a further 3 d post challenge. Significantly larger reductions in lung virus titers were observed in the mice receiving xylitol than in the controls receiving phosphate-buffered saline (PBS). In addition, fewer CD3+ and CD3+CD8+ lymphocytes, whose numbers reflect inflammatory status, were recruited in the mice receiving xylitol. These results indicate that dietary xylitol can ameliorate hRSV infections and reduce inflammation-associated immune responses to hRSV infection.

We present a microRNA (miRNA) detection method that achieves enhanced sensitivity by means of a power-free microfluidic chip without the requirement of an external power source. The miRNA detection is completed by sandwich hybridization between probe DNAs and target miRNA with small sample volume (0.5 μL) within 20 min. Fluorescence signals after hybridization were amplified by laminar flow-assisted dendritic amplification (LFDA) using fluorescein isothiocyanate (FITC)-labeled streptavidin (F-SA) and biotinylated anti-streptavidin (B-anti-SA) as amplification reagents. To enhance the sensitivity of on-chip miRNA detection, the hybridization buffer solution was newly optimized with three main components—sodium dodecyl sulfate (SDS), formamide and dextran sulfate—that are known to strongly influence hybridization. An on-chip miRNA detection test in the newly optimized hybridization buffer (0.2% SDS, 5% formamide and 1% dextran sulfate) revealed dramatic increases in both the LFDA signal in the sample channel and the signal-to-background ratio (S/B ratio). Moreover, the LFDA signals in a blank reference channel remained low due to the suppression of non-specific bindings and hybridizations. By changing the hybridization buffer, we obtained an improved limit of detection (LOD) that was 0.045 pM (miRNA-196a) and 0.45 pM (miRNA-331), which are around 30- and 10-fold better than that of when control hybridization buffer was used. The improved performance of our miRNA detection system with short running time and high sensitivity could contribute to future research, including point-of-care diagnostic systems.

Malanjkhand copper project, Madhya Pradesh, India, generates a lot of lean sulphidic ores containing chalcopyrite (∼0.3% of copper) with traces of oxidized, semi-oxidized and secondary sulfides. EPMA analysis shows that the granitic rock samples have plagioclase feldspar, orthoclase feldspar and quartz as major constituents within which the ore minerals are sparsely distributed. Due to the complex structure and low solubility of the sulphide-bearing granitic rock, the dissolution of copper from the hard matrix is difficult. The present study deals with change in crystallographic and chemical nature of the mineral system present in the host rock. In an attempt to increase copper recovery, the ore was subjected to heating at 600°C under normal atmospheric conditions. This heat treatment resulted in enhanced copper recovery, up to 98% within 60 days of progressive leaching.

[Purpose] The purpose of this study is to investigate the effects of virtual reality training using Nintendo Wii on balance and walking for stroke patients. [Subjects and Methods] Forty stroke patients with stroke were randomly divided into two exercise program groups: virtual reality training (n=20) and treadmill (n=20). The subjects underwent their 40-minute exercise program three times a week for eight weeks. Their balance and walking were measured before and after the complete program. We measured the left/right weight-bearing and the anterior/posterior weight-bearing for balance, as well as stance phase, swing phase, and cadence for walking. [Results] For balance, both groups showed significant differences in the left/right and anterior/posterior weight-bearing, with significant post-program differences between the groups. For walking, there were significant differences in the stance phase, swing phase, and cadence of the virtual reality training group. [Conclusion] The results of this study suggest that virtual reality training providing visual feedback may enable stroke patients to directly adjust their incorrect weight center and shift visually. Virtual reality training may be appropriate for patients who need improved balance and walking ability by inducing their interest for them to perform planned exercises on a consistent basis.

[Purpose] The objective of this study was to investigate the effects of spinal support device (SSD) on pain and hamstring extensibility in patients with non-specific low back pain (NSLBP). [Subjects and Methods] 20 patients with NSLBP were recruited and randomly assigned to either the SSD group or the control group. In the SSD group, SSD was applied; in the control group, bed rest in supine position was performed. Both groups underwent treatment 20 min/day, 3 times a week, for a duration of 4 weeks. To assess the hamstring extensibility, sit and reach test (SRT) was performed. To assess pain pressure threshold (PPT) of the sacroiliac joint, a pressure algometer was used. Visual analog scale (VAS) was used to quantify pain. [Results] The SSD group showed a significant improvement in sacroiliac joint pain with increased VAS, and the control group showed a significantly increased VAS after intervention. In the SSD group, VAS was significantly increased, but SRT was not changed compared with the control group. [Conclusion] These results demonstrated that an application of SSD effectively attenuates low back pain. Therefore, SSD may be a suitable intervention for pain control in patients with NSLBP.

To increase the photosynthesis of crop and improve plant quality, we evaluated the effect of elevated CO2 on vegetative growth and flowering in Phalaenopsis Fuller’s Pink Swallow. Plants were exposed to 450 (control), 800, 1600, and 2400 μmol·mol−1 CO2 for 31 weeks. The number of leaves, leaf length, and leaf width displayed greater increases in plants grown under 1600 and 2400 μmol·mol−1 CO2 than in plants grown under 450 and 800 μmol·mol−1 CO2. The times to leaf initiation were reduced to 90.7 and 85.8 days in plants grown under 1600 and 2400 μmol·mol−1 CO2, respectively, compared with that of the control, 177.1 days. The leaf elongation rate was significantly increased in plants grown under 1600 and 2400 μmol·mol−1 CO2 compared to plants grown under 450 and 800 μmol·mol−1 CO2. Plants grown under 1600 μmol·mol−1 CO2 had the highest total number of flower buds among all plants grown under the four tested CO2 concentrations. Leaf injuries were not observed in any plants regardless of CO2 concentration, but flower bud abortion and bud withering were observed in CO2-enriched plants, especially in plants grown under 1600 and 2400 μmol·mol−1 CO2. Plants subjected to long-term CO2 elevation of over 800 μmol·mol−1 displayed increased biomass production despite a concomitant reduction in the number of buds. These results showed that 1600 and 2400 μmol·mol−1 CO2 significantly enhanced the vegetative growth of Phalaenopsis. However, long-term exposure to high CO2 concentrations can adversely affect the flowering of Phalaenopsis, and result in reduced flower production and increased flower bud abortion.

In this study, the chemical composition and anti-inflammatory activities of hydrodistilled essential oil from Farfugium japonicum were investigated for the first time. The chemical constituents of the essential oil were further analyzed by GC-MS and included 1-undecene (22.43%), 1-nonene (19.83%), β-caryophyllene (12.26%), α-copaene (3.70%), γ-curcumene (2.86%), germacrene D (2.69%), and 1-decene (2.08%). The effects of the essential oil on nitric oxide (NO) and prostaglandin E2 (PGE2) production in lipopolysaccharide (LPS)-activated RAW 264.7 macrophages were also examined. The results indicate that the F. japonicum essential oil is an effective inhibitor of LPS-induced NO and PGE2 production in RAW 264.7 cells. These inhibitory effects of the F. japonicum essential oil were accompanied by dose-dependent decreases in the iNOS and COX-2 mRNA expression. In order to determine whether F. japonicum essential oil can safely be applied to human skin, the cytotoxic effects of F. japonicum essential oil were determined by colorimetric MTT assays in human dermal fibroblast and keratinocyte HaCaT cells. F. japonicum essential oil exhibited low cytotoxicity at 100 μg/mL. Based on these results, we suggest that F. japonicum essential oil may be considered a potential anti-inflammatory candidate for topical application.

The aims of this study were to examine the effects of different temperatures on seed germination and initial long-day (LD) or short-day (SD) duration on growth, floral initiation, and development of Hosta yingeri S.B.Jones. The germination percentage of H. yingeri seeds was > 90% at 5°C and between 15°C–30°C. The lowest time to the first germination (TFG) and the mean germination time (MGT) were observed at around 30°C. The optimum temperature for germination can be around 30°C considering the final germination percentage, TFG, and MGT together. Plant height, number of leaves, and leaf length increased as the initial SD duration decreased. The percentages of plant bearing buds were 50%, 50%, 20%, 10%, and 0% when the initial SD treatments were 0, 3, 6, 9, and 12 weeks with 29, 26, 23, 20, and 17 weeks of LDs, respectively. No plants flowered when they were exposed to the initial LD conditions. Flower spike length, number of visible buds, and number of open flowers increased as the duration of the initial SD decreased. Four-week-old H. yingeri required ≥ 26 weeks of LD duration to achieve >50% flowering.

The clinical outcome of patients with acute myocardial infarction (MI) with unprotected left main coronary artery (LMCA) stenosis is not fully understood. We sought to assess the outcomes of patients with acute MI who underwent percutaneous coronary intervention (PCI) for unprotected LMCA stenosis. A total of 587 patients enrolled in the Korea Acute Myocardial Infarction Registry with LMCA stenosis were analyzed. Patients with culprit LMCA had higher inhospital mortality than patients with non-culprit LMCA (16.0% versus 8.9%, P = 0.008), but had similar clinical outcomes during a 12-month follow-up. Compared to CABG, PCI using drug-eluting stents (DES) was more frequently performed with similar early and 12-month clinical outcomes. The efficacy of sirolimus-eluting stents, paclitaxel-eluting stents, and zotarolimus-eluting stents were comparable at 12-month clinical follow-up. Predictors of 12-month mortality included mechanical ventilation, cardiogenic shock, age > 65 years, and ejection fraction < 40%. Patients with acute MI and culprit LMCA have higher early mortality than patients with non-culprit LMCA. PCI with DES is frequently performed and the clinical outcome is similar between the 3 types of first-generation DES.
