  • This study investigated the effects of alginate oligosaccharide on lipid metabolism in mice fed a high-cholesterol diet for 6 weeks. Male apoE mice were assigned to four groups: normal diet group (N), high-cholesterol diet group (HC), HC with 5% alginate oligosaccharide group (HC-AOL), and 10% alginate oligosaccharide group (HC-AOH). Epididymal adipose tissue and kidney adipose tissue weights were significantly reduced in the HC-AOH group by 131.4% and 148.4%, respectively, as compared to the HC group. Serum total cholesterol (TC), triglyceride (TG), and LDL-cholesterol levels were also significantly reduced in the HC-AOH group by 57.5%, 51.4%, and 82.9%, respectively, as compared to the HC group. Hepatic TC and TG levels in the HC-AOH group were significantly reduced by 72.3% and 33.5%, respectively, as compared to the HC group. These results indicate that alginate oligosaccharide might improve lipid metabolism and reduce fat accumulation.

  • The imogolite synthesis wore performed by using tetraethoxysilane (TEOS) and aluminium-sec-butoxide (ASB) at < $100^{\circ}C$. A mixure of TEOS and ASB in a molar ratio of 1:2 was prepared under vigorous stirring and the experiments were performed under the hydrothemal refluxing condition. When the concentration of TEOS and ASB in solution was 0.5 M, a well-crystallized imogolite was synthesized, and the reflections wore shown at d = 22.4, $9.5\;\AA$ etc., after XRD analysis. DTA analysis shows 2 exothemal peaks at 68 and $249^{\circ}C$, suggesting the dehydration and the dehyroxylation reaction, respectively. The result of TG indicates 41% weight loss. And the weak and unsymmetrical peaks by the Si-O-Al stretching vibrations at 953 and $993cm^{-1}$ and by O-Si-O bending vibration at $562cm^{-1}$ were observed after IR analysis. The synthetic imogolite was fibrous and shows a spiders web like network structure.

  • Methane, as a greenhouse gas, is some 21~25 times more detrimental to the environmental than carbon dioxide. Landfills generally constitute the most important anthropogenic source, and methane emission from landfill was estimated as 35~73 Tg per year. Biological approaches using biocover (open system) and biofilter (closed system) can be a promising solution for older and/or smaller landfills where the methane production is too low for energy recovery or flaring and installation of a gas extraction system is inefficient. Methanotrophic bacteria, utilizing methane as a sole carbon and energy source, are responsible for the aerobic degradation (oxidation) of methane in the biological systems. Many bench-scale studies have demonstrated a high oxidation capacity in diverse filter bed materials such as soil, compost, earthworm cast and etc. Compost had been most often employed in the biological systems, and the methane oxidation rates in compost biocovers/boifilters ranged from 50 to $700\;g-CH_4\;m^{-2}\;d^{-1}$. Some preliminary field trials have showed the suitability of biocovers/biofilters for practical application and their satisfactory performance in mitigation methane emissions. Since the reduction of landfill methane emissions has been linked to carbon credits and trading schemes, the verified quantification of mitigated emissions through biocovers/biofilters is very important. Therefore, the assessment of in situ biocovers/biofilters performance should be standardized, and the reliable quantification methods of methane reduction is necessary.

  • This research was designed to investigate the effects of Estromon including FGF271 (Female Growth Factor 271) which was developed as a phytoestrogen for post- and pre-menopausal syndrome (PMS). The oral administration of two capsules of Estromon twice a day for 3 months significantly improved PMS (Post-/Premenopausal Syndrome) about 5 times more than placebo group (OR=5.04, 95% C.1. 1.40-18.14). In the group of 24 patients having taken Estromon, the concentration of alkaline phosphatase asn the bone marker decreased by -9.3${\pm}$9.5 IU/L after 3 months with a statistic significance. Since the concentration of osteocalcin as the other bone marker also decreased in more patients in Estromon group than in placebo group, the bone density might be expected to be improved in long-term treatment. Serum human growth hormone level increased in 17 out of 24 patients. Triglycerides decreased by -8.0${\pm}$40 (mg%) after 1 month and by -4.4${\pm}$36 (mg%) after 3 months in Estomon group while triglycerides increased in both cases in placebo group (p.0.01). Therefore, PMS patients might benefit from Estromon as a phytoestrogen supplement without any serious side effects.

  • This study examined the effects of the dietary inclusion of various concentrations of red ginseng byproduct (RB) and a mixture containing red ginseng byproduct, garlic extract, yeast and filler (CR) on the growth, body composition, serum chemistry, and lysozyme activity of juvenile olive flounder (Paralichthys olivaceus). Juvenile fish (n= 630) weighing 5.0 g were randomly distributed into 21 180 L flow-through tanks (30 fish/tank). Seven experimental diets were prepared in triplicate: a control diet without additive, and diets containing 0.5, 1 and 2% concentrations of RB (RB-0.5, RB-1, RB-2) and CR (CR-0.5, CR-1, CR-2) at the expense of wheat flour. After an 8-week feeding trial, serum chemistry and lysozyme activity of fish were measured. Mean weight gain was significantly higher in fish fed the control diet than in fish fed the RB and CR diets. The dietary inclusion of RB and CR reduced feed utilization. Mean serum glucose and triglyceride (TG) levels were higher in fish fed the control diet than in fish fed the other diets. Mean glutamate pyruvate transaminase (GPT) levels of fish fed the control and RB-2 diets were higher than those of fish fed the RB-0.5, RB-1, CR-1, and CR-2 diets. Mean lysozyme activity levels of fish fed the RB-0.5 and RB-1 diets were higher than those of fish fed the control and CR diets. The results of this study indicate that red ginseng byproduct may be utilized as an immunostimulant rather than as a growth promoter for juvenile olive flounder. Dietary inclusion of 0.5% red ginseng byproduct effectively improved serum glucose, GPT, TG, and lysozyme activity of the fish in this study.

  • Li-Mn spinel ($LiMn_2O_4$) is prepared by a hydrothermal process with K-Birnessite ($KMnO_4{\cdot}yH_2O$) as a precursor. The K-Birnessite obtained via a hydrothermal process with potassium permanganate [$KMnO_4$] and urea [$CO(NH_2)_2$] as starting materials are converted to Li-Mn spinel nanoparticles reacting with LiOH. The molar ratio of LiOH/K-Birnessite is adjusted in order to find the effect of the ratio on the structural, morphological and electrochemical performances of the Li-Mn spinel. X-ray diffraction (XRD) and field emission scanning electron microscopy (FE-SEM), energy-dispersive X-ray spectroscopy (EDS), and thermogravimetry (TG) are used to investigate the crystal structure and morphology of the samples. Galvanostatic charge and discharge are carried out to measure the capacity and rate capability of the Li-Mn spinel. The capacity shows a maximum value of $117\;mAhg^{-1}$ when the molar ratio of LiOH/K-Birnessite is 0.8 and decreases with the increase of the ratio. However the rate capability is improved with the increase of the ratio due to the reduction of the particle size.

  • Objectives : The present study investigated effects of Artemisia Capillaris Thunberg ethanol extract(EtOH ext). on lowering lipid, anti-oxidation and concentration of plasma inflammatory mediators using rat fed on high oxidized fat. Methods : We divided fat sprague-dawley rats fed on high oxidized into 4 groups. They were normal group, feed with 100 mg/kg Artemisia Capillaris Thunberg group, feed with 200 mg/kg Artemisia Capillaris Thunberg group and feed with 300 mg/kg Artemisia capilaris Thunberg group. They were administered for 4 weeks. We measured concentration of plasma free fatty acid(FFA), plasma triglyceride, plasma total cholesterol, and plasma low density lipoprotein-cholesterol(LDL-cholesterol), plasma high density lipoprotein-cholesterol(HDL-cholesterol), concentration of liver total cholesterol and liver triglyceride (TG), concentration of plasma thiobarbituric acid reactive substance(TBARS) and liver thiobarbituric acid reactive substance(TBARS), glutathione peroxidase (GSH-Px) activity, superoxide dismutase(SOD) activity and catalase(CAT) activity, plasma nitric oxide(NO), ceruloplasmin and ${\alpha}-glycoprotein$. Results : 1. The Artemisia Capillaris Thunberg EtOH ext. groups showed low concentration of plasma FFA, plasma triglyceride, plasma total cholesterol and plasma LDL-cholesterol compared to control group. However, concentration of plasma HDL-cholesterol was increased in the Artemisia Capillaris Thunberg EtOH ext. groups. 2. Concentration of liver total cholesterol and liver TG showed a significantly decrement in all Artemisia Capillaris Thunberg EtOH ext. groups than that of control group. 3. The Artemisia Capillaris Thunberg EtOH ext. groups showed lower values in concentration of plasma TBARS and liver TBARS than that of control group. The values of GSH-Px activity, SOD activity and CAT activity were increased in the Artemisia Capillaris Thunberg EtOH ext. groups. 4. The values of plasma NO, ceruloplasmin and ${\alpha}-glycoprotein$ were decreased in Artemisia Capillaris Thunberg EtOH ext. groups. Conclusions : Based on the results in this study, the Artemisia Capillaris Thunberg EtOH ext. showed a positive effect in lowering lipid, anti-oxidation and decrement of plasma inflammatory mediators.

  • Objectives: The aim of this study is to investigate the effect of a Dachaihu decoction for hyperlipidemic acute pancreatitis (HLAP) by systematic review and meta-analysis of Chinese clinical studies. Methods: China National Knowledge Infrastructure (CNKI) was utilized as the major search engine. The date of the literature search was March 7, 2020. Randomized controlled trials (RCTs) about using a Dachaihu decoction for HLAP were included in this study. Meta-analysis was performed by synthesizing outcome data, including total effective rate, abdomen pain relief time, first bowel movement time, blood amylase recovery time, and triglyceride (TG) levels (mmol/L). The selected literature was assessed using Cochrane's risk of bias (RoB). Results: Twelve of 44 RCTs met the inclusion criteria. Most studies were evaluated with RoB as having unclear risk. The total effective rate of herbal medicine treatment based on the Dachaihu decoction was significantly higher than that of symptomatic supportive treatment in 10 articles (risk ratio=1.15, 95% CI: 1.08 to 1.21, p<0.00001, I2=0%). Herbal medicine treatment based on a Dachaihu decoction was significantly more effective than symptomatic supportive treatment in terms of reducing abdomen pain relief time (in all articles; mean difference=-1.70, 95% CI: -1.91 to -1.41, p<0.00001, I2=45%), first bowel movement time (in 7 articles; mean difference=-1.46, 95% CI: -1.86 to -1.05, p<0.00001, I2=73%), blood amylase recovery time (in 8 articles; mean difference=-1.48, 95% CI: -2.04 to -0.92, p<0.00001, I2=90%), and TG levels (in 8 articles; mean difference=-1.59, 95% CI: -2.28to -0.91, p<0.00001, I2=90%). Only one article reported side effects of treatment among the intervention group and control group, citing pancreatic ulcer and pancreatic pseudocyst formation. Conclusions: This study suggests that herbal medicine treatment based on a Dachaihu decoction could yield higher efficacy for HLAP than symptomatic supportive treatment alone. However, the results might be somewhat biased because of the poor quality and small sample size of the included RCTs. Well-qualified clinical studies are needed to prove the effectiveness of Dachaihu decoction therapy for HLAP.

  • Carry over contamination has been reduced in some systems by flushing the internal and external surfaces of the sample probe with copious amount of diluent. It between specimens should be kept as small as possible. A built-in, continuous-flow wash reservoir, which allows the simultaneous washing of the interior and exterior of the syringe needles, addresses this issue. In addition, residual contamination can further be prevented through the use of efficient needle rinsing procedures. In discrete systems with disposable reaction vessels and measuring cuvets, any carry over is entirely caused by the pipetting system. In analyzers with reuseable cuvets or flow cells, carry over may arise at every point through which high samples pass sequentially. Therefore, disposable sample probe tips can eliminate both the contamination of one sample by another inside the probe and the carry over of in specimen into the specimen in the cup. The results of the applicative carry over experiment studied on 21 items for total protein (TP), albumin (ALB), total bilirubin (TB), alkaline phosphatase (ALP), aspratate aminotranferase (AST), alanine aminotranferase (ALT), gamma glutamyl transferase (GGT), creatinine kinase (CK), lactic dehydrogenase (LD), creatnine (CRE), blood urea nitrogen (BUN), uric acid (UA), total cholesterol (TC), triglyceride (TG), glucose (GLU), amylase (AMY), calcium (CA), inorganic phosphorus (IP), sodium (Na), potassium (K), chloride (CL) tests in chematology were as follows. Evaluation of process performance less than 1% in all tests was very good, but a percentage of ALB, TP, TB, ALP, CRE, UA, TC, GLU, AMY, IP, K, Na, and CL was 0%, implying no carry over. Other tests were ALT(-0.08%), GGT(-0.09%), CK(0.08%), LD(0.06%), BUN(0.12%), TG (-0.06%), and CA(0.89%).
