Human rhinoviruses (HRVs) are a major cause of the common cold and until now there is no registered clinically effective antiviral chemotherapeutic agent for treatment diseases caused by HRVs. Our previous report showed that gallic acid from Woodfordia fruticosa flowers possessed antioxidant activity. Many studies reported antioxidants possess activities against various viruses. Therefore, we examined activity HRVs mode its actions observing effect on HRV-induced cytopathic (CPE) infectivity...
Harmful algal blooms have negatively affected the aquaculture industry and aquatic ecosystems globally. Remote sensing using satellite sensor systems has been applied on large spatial scales with high temporal resolutions for effective monitoring of harmful in coastal waters. However, oceanic color satellites limitations, such as low resolution optical complexity In this study, bands 1 to 4, obtained from Landsat-8 Operational Land Imager images, were used evaluate performance empirical...
The early detection of faulty batteries is a critical work in the manufacturing processes secondary rechargeable battery. Conventional approaches use original performance degradation profiles remaining capacity after recharge order to detect batteries. However, with right-truncated test duration may not be effective detecting In this correspondence, we propose dual features functional support vector machine approach that uses both first and second derivatives for reduced error rate. modified...
Department of Herbal Resources, Professional Graduate School Oriental Medicine and Institute Basic Natural Sciences, Wonkwang University, Iksan 570-749, KoreaReceived August 20, 2003Key Words : Antioxidant activity, Acer ginnala Max., DPPH radical scavenging activityNatural antioxidants such as α-tocopherol L-ascorbicacid are widely used because they seen being safer andcausing fewer adverse reactions, but their antioxidant activitiesare, however, lower than those synthetic suchas butylated...
The traditional manufacturing method used to produce goods from Hizikia fusiforme, utilizes extraction steps with hot water. byproduct (of water extraction) is rich in polysaccharide and considered a waste. To evaluate the osteogenic effects of H. fusiforme (HFB), cells animal models were test it on osteogenesis. HFB-treated mouse myoblast C2C12 exhibited significant dose dependently elevated alkaline phosphatase (ALP) activity slightly increased bone morphogenetic protein-2 (BMP-2). HFB...
Background: While recovery from remifentanil is fast due to its rapid metabolism, it can induce hyperalgesia by activation of N-methyl-D-aspartic acid (NMDA) receptors.Therefore, administration NMDA receptor antagonists such as ketamine effective in relieving caused remifentanil.A previous study showed that nefopam before anesthesia combined with low-dose reduced pain and analgesic consumption during the immediate postoperative period.We hypothesized intraoperative infusion laparoscopic...
Abstract Inhibitors of melanin biosynthesis were screened by using three different methods. The extract Veratrum patulum contains hydroxystilbene compounds that are potent tyrosinase inhibitors. We evaluated the enzyme inhibitory property on mushroom including resveratrol, oxyresveratrol, and their analogs. Biotransformation cellulase whole brought about an increase in activity products tyrosinase. enhancement inhibition is supposed to concentration aglycon, which has superior its glycoside....
The sap of A. ginnala Max. has been used for treatment stomachic and diarrhea. 1The plant, Max.(family Aceraceae) grows as a perennial herb is widely distributed in Korea.Among the plants examined, Acer ginnala, lllicium Cornus macrophylla exerted most strong inhibitory activity on aldose reductase. 2Phytochemical studies this plant have so far yielded poligalitol, 3 acertannin, 4,5 polygagallin. 6A methanol solution DPPH free radical was found to be stable more than 60 min by...
Background: Fat grafting has been widely used for facial rejuvenation and soft tissue reconstruction. However, it is associated with a lower retention rate than expected complications such as fat necrosis or calcification. Several techniques that may increase the survival of grafts have proposed. The promote recipient sites vascularity to include administration growth factors, platelet- rich plasma, adipose derived-stem cells preconditioning graft site. Methods: In this study, authors...
Bioactivity-directed isolation work on the New Zealand liverwort Hepatostolonophora paucistipula afforded sesquiterpene lactones (-)- ent-costunolide (1) and ent-arbusculin B (2) as cytotoxic compounds. This is first report of 1, enantiomeric to known germacranolide (+)-costunolide (3).
Methyl-4-[[(2E)-3,7-dimethyl-2,6-octadienyl]oxy]-3-hydroxybenzoate (5) has been identified from the New Zealand liverwort Trichocolea hatcheri (T. hatcheri) on basis of spectroscopic evidence. This compound was tested for its growth inhibitory effects against tumor cell lines, using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay. It showed inhibition activity Staphylococcus epidermidis (MIC, 1,000 <TEX>${\mu}$</TEX>g/mL). These results suggest that 5 possesses...
The gastroprotective activity of phytos-phingosine hydrochloride (PS-HCl, CAS 554-62-1) was assessed in four different rat models experimentally induced gastric ulcer. Various doses (2.5-10 mg/kg) PS-HCl were orally administered to rats 30 min before the treatment with HCl/ethanol, indometacin, cysteamine, or ligated pylorus. Oral administration prevented acute ulcer formation 4 types a dose-dependent manner as follows: (1) HCl/ethanol-induced mucosal membrane lesions (20.1-47.8 %...
The antiviral activity of 13(E)-labd-13-ene-8alpha,15-diol (1), isolated from Brachyglottis monroi, was examined against human rhinovirus 2 (HRV2) and 3 (HRV3), the anticancer on cancer cells (A549 Hep2). Compound (1) showed strong anti-HRV2 HRV3 with a 50% inhibitory concentration (IC(50)) 2.68 0.87 microg/mL, respectively, cytotoxicity (CC(50)) 59.45 microg/mL. Ribavirin only anti-HRV3 an IC(50) 30.48 microg/mL CC(50) > 100 addition compound to HRV-infected HeLa directly reduced formation...
