Characteristics of the Drip-and-Ship Paradigm for Patients with Acute Ischemic Stroke in South Korea.

BACKGROUND: Data on the drip-and-ship paradigm in Korea are limited. The present study aimed to evaluate the use of the drip-and-ship paradigm and the time delays and outcomes associated with the paradigm in Korea. METHODS: We used data from the Clinical Research Center for Stroke-5 registry between January 2011 and March 2014. Among patients treated with tissue-type plasminogen activator (tPA), the use of the drip-and-ship paradigm was evaluated, and time delays and functional outcomes at 3 months were compared between patients treated with the paradigm and those treated directly at visits. RESULTS: Among 1843 patients who met the eligibility criteria, 244 patients (13.2%) were treated with the drip-and-ship paradigm. Subsequent endovascular recanalization therapy was used in 509 patients (27.6%). The median time from symptom onset to groin puncture was greater in patients treated with the paradigm than in those treated directly at visits (305 versus 200 minutes, P < .001). In multivariate analysis, the risks of unfavorable functional outcomes and symptomatic intracranial hemorrhage were higher inpatients treated with the paradigm than in those directly treated at visits (odds ratio [OR] 2.15; 95% confidence interval [CI], 1.50-3.08; P < .001 and OR 1.78; 95% CI, 1.02-3.12; P = .041, respectively). CONCLUSIONS: In Korea, the drip-and-ship paradigm was used in less than 15% of all patients treated with tPA. The use of the paradigm might cause an increase in the onset-to-groin puncture time. Additionally, clinical outcomes might be worse in patients treated with the paradigm than in those treated directly at visits.

Extraction of rutin from Tartary buckwheat milling fractions and evaluation of its thermal stability in an instant fried noodle system.

Extraction conditions of rutin from buckwheat milling fractions were established and a rutin-enriched material (REM, 31.8g/100g of rutin) was successfully obtained by the ultrasonic-assisted ethanol method (steaming, 16-150 mesh particle size, 70% ethanol, and ultrasonication at 40°C for 30min). When REM was applied to instant fried noodles (1% and 2% by weight of wheat flour) for rutin fortification, the levels of rutin in the noodles were determined to be about 250-500mg/100g which corresponded to the recommended daily dose of rutin. While frying temperatures (150-190°C) and times (1-3min) did not negatively affect the level of rutin in the instant fried noodles, the distinct loss of rutin was observed after cooking. Furthermore, REM did not significantly affect the oil uptake and mechanical property of instant fried noodles. The strong antioxidant activity of rutin in REM contributed to retarding the oxidative deterioration of the noodles during storage.

Associations between intakes of individual nutrients or whole food groups and non-alcoholic fatty liver disease among Korean adults.

BACKGROUND AND AIM: Dietary factors are closely associated with the risk of non-alcoholic fatty liver disease (NAFLD). Asian and Western diets differ in energy-nutrient composition, fatty-acid composition, and main nutritional sources; therefore, the implications would be limited if the Western-oriented study results were applied to Asian patients. We aimed to identify the nutrient and food group intakes of a typical Asian diet and assess their effects on NAFLD risk. METHODS: In total, 348 subjects were recruited from 5 participating hospitals. Information on sociodemographic characteristics and health-related behaviors were obtained through face-to-face interviews. NAFLD was diagnosed by ultrasound. Dietary intakes were assessed with a 24-h recall applying a multiple-pass approach and 4-day food records that included 1 or 2 weekend days. RESULTS: There were no significant differences in health-related behaviors between the cases and controls except for smoking behavior. The cases had elevated triacylglycerol, fasting glucose, and low-density lipoprotein cholesterol levels compared with the controls. In men, after adjusting for variables, low intakes of vitamin C (odds ratio [OR], 4.23), vitamin K (OR, 3.93), folate (OR, 3.37), omega-3 fatty acids (OR, 2.16), and nuts and seeds (OR, 3.66) were associated with a significantly higher risk for developing NAFLD. In women, vitamin K (OR, 2.54) and vegetable (OR, 4.11) intakes showed a significant beneficial effect for lowering NAFLD risk. CONCLUSIONS: Adequate intakes of vitamin C, vitamin K, folate, omega-3 fatty acids, nuts and seeds, and vegetables may help in preventing NAFLD in Korean adults.

Draft genome sequencing of Bacillus sp. strain M2-6, isolated from the roots of Korean ginseng, Panax ginseng C. A. Meyer, after high-hydrostatic-pressure processing.

A bacterium, designated M2-6, was isolated from Korean ginseng, Panax ginseng C. A. Meyer, roots after high-hydrostatic-pressure processing. On the basis of 16 rRNA gene phylogeny, the isolate was presumptively identified as a Bacillus sp. Here we report the draft genome sequence of Bacillus sp. strain M2-6 (= KACC 16563).

A comparison between high hydrostatic pressure extraction and heat extraction of ginsenosides from ginseng (Panax ginseng CA Meyer).

BACKGROUND: To determine biomaterial components, the components must first be transferred into solution; thus extraction is the first step in biomaterial analysis. High hydrostatic pressure technology was used for ginsenoside extraction from ginseng roots. In the extraction of fresh and red ginseng, high hydrostatic pressure extraction (HHPE) was found to be more effective than heat extraction (HE). RESULTS: In fresh ginseng extraction under HHPE, total ginsenosides (1602.2 µg mL⁻¹) and ginsenoside metabolite (132.6 µg mL⁻¹) levels were slightly higher than those under HE (1259.0 and 78.7 µg mL⁻¹), respectively. In red ginseng, similar results indicated total ginsenoside and ginsenoside metabolite amounts according to the extraction methods. Most volatile compounds by HHPE were higher than by HE treatment. HHPE of red ginseng was conducted under four pressures: 0.1 MPa (1 atm), 30, 50, and 80 MPa. Total sugar, uronic acid, and polyphenol amounts increased until 30 MPa of pressure and then showed decreasing tendencies. Total ginsenoside and ginsenoside metabolite contents linearly increased with increasing pressure, and a maximum was reached at 80 MPa for the metabolites. CONCLUSION: HHPE used for red ginseng processing contributes to enhanced extraction efficiencies of functional materials such as ginsenosides through cell structure modification.
