YJ YJ Kim: Influence Statistics

BACKGROUND: Systolic blood pressure of more than 185 mm Hg is a contraindication to thrombolytic treatment with intravenous alteplase in patients with acute ischaemic stroke, but the target systolic blood pressure for optimal outcome is uncertain. We assessed intensive blood pressure lowering compared with guideline-recommended blood pressure lowering in patients treated with alteplase for acute ischaemic stroke.

METHODS: We did an international, partial-factorial, open-label, ...

The combined effect of aqueous chlorine dioxide (ClO2) and fumaric acid as a chemical treatment to inactivate pre-existing microorganisms was evaluated using broccoli sprouts. Broccoli sprouts were treated with distilled water, 50ppm ClO2, 0.5% fumaric acid, and a combination of 0.5% fumaric acid and 50ppm ClO2. Treatment with 50ppm ClO2 and 0.5% fumaric acid reduced the initial populations of total aerobic bacteria, yeasts and molds, and coliforms in broccoli sprouts by 2.70, 2.46, and ...

OBJECTIVES: While socio-economic status (SES) is considered a key social-environment factor affecting health outcomes, sex differences in the association between SES and the risk of type 2 diabetes remain unclear. The aims of this study were: (1) to identify risk factors associated with type 2 diabetes in a representative sample of Korean adults with a focus on socio-economic determinants; and (2) to examine how the association between SES and type 2 diabetes is affected by sex.

BACKGROUND: Although there have been growing concerns about the adverse effects of air pollution on birth outcomes, little is known about which specific exposure times of specific pollutants contribute to low birth weight (LBW).

METHODS: We evaluated the relationships between LBW and air pollution exposure levels in Seoul, Korea. Using the air pollution data, we estimated the exposure during each trimester and also during each month of pregnancy on the basis of the gestational age and ...

AIMS: To isolate predominant ruminal bacteria that produce trans-10, cis-12 conjugated linoleic acid (CLA) from linoleic acid (LA).

METHODS AND RESULTS: Mixed bacteria from ruminal contents of a cow fed grain were enriched with DL-lactate and trypticase. They produced more trans-10, cis-12 CLA than those that were not enriched (7 vs 2 microg mg protein(-1), P < 0.05). Enrichments had an abundance of large cocci that produced trans-10, cis-12 CLA from LA. Strain YJ-4 produced the most ...

BACKGROUND/AIMS: Mucinous gastric carcinoma (MGC) is a histopathologic subtype of gastric carcinoma with a poor prognosis. The purpose of this study was to compare the disease course of MGC with non-mucinous gastric carcinoma (NMGC) and study the clinicopathologic features that influence the prognosis of MGC patients.

METHODS: We reviewed the records of 2,383 patients with a confirmed histologic diagnosis of gastric carcinoma. There were 157 patients with MGC compared to 2,226 with ...

Fine particle (aerodynamic diameter <2.5 microm) samples were collected during six intensive measurement periods from November 2001 to August 2003 at Gosan, Jeju Island, Korea, which is one of the representative background sites in East Asia. Chemical composition of these aerosol samples including major ion components, trace elements, organic and elemental carbon (OC and EC), and particulate polycyclic aromatic hydrocarbons (PAHs) were analyzed to study the impact of long-range transport ...

Fresh semimembranosus pork was marinated with garlic or onion juice to determine their effect on lipid oxidation and meat quality during cold storage. Five marinade treatments, which include control (C) and two levels (3 and 6%) of garlic juice (GJ) or onion juice (OJ), were prepared and stored for 7 days at 4C. pH, color, thiobarbituric acid reactive substances (TBARS) values, peroxide value (POV) and sensory evaluations of meat were determined at 1, 3 and 7 days of storage. The pH ...

A single orthodontic activation lasting one hour can initiate tooth movement. The purpose of this study is to examine tooth movement, osteoclasts, and root resorption in rats following several one-hour activations. Rats (n = 144) were randomly assigned to intermittent (multiple activations of 1 hr/day), continuous, and sham appliances. Twelve rats were killed at 3, 5, 7, and 14 days. Tooth movement, osteoclasts, osteoclast %, and root resorption % were quantified. Continuous force moved ...

Lipid oxidation and oxidative products as affected by pork meat cut, packaging method, and storage time were evaluated during refrigerated storage. Pork belly had higher pH and thiobarbituric acid reactive substance (TBARS) values than pork loin, and aerobic-packaged belly had higher TBARS than vacuum-packaged counterparts. Loin had higher free fatty acid (FFA) values than belly, and increased FFA values were observed with increased storage time. Peroxide values increased up to 7 d and ...

ABSTRACT: The application of conjugated linoleic acid (CLA) as a functional ingredient has been limited due to the high cost of purification and its water-insoluble nature. In this study, high-purity CLA was obtained from safflower oil and a hydrophilic form of CLA was produced by complexation with arginine (Arg). CLA was prepared by alkali-isomerization and purified up to 95% using urea-inclusion crystallization. Total purified CLA comprised 41% and 50% of cis-9, trans-11 and trans-10, ...

BACKGROUND: Although the exact mechanism of TENS pain relief is unknown, it is believed that TENS impulses interrupt nociceptive signals at the dorsal horn of the spinal cord.

AIMS: To evaluate the hypotheses that during pain caused by noxious stimuli, brain responses, temporal summation and brain functional connectivity are modulated by TENS, and that mechanisms of pain relief by TENS differ between men and women.

METHODS: During fMRI scanning, the same noxious stimuli were delivered to ...

Titanium matrix composites (TMCs) have several attractive characteristics including high temperature properties, wear resistance and oxidation resistance. In the case of metal matrix composites, it is generally desirable to select reinforcements that exhibit suitable interfaces with the matrix, high temperature stability, and similar coefficients of thermal expansion with respect to the matrix. Conventional candidates for reinforcements in TMCs include SiC, Si3N4, Al2O3, TiC, TiN, TiB, ...

The commissioning and the initial operation for the first plasma in the KSTAR device have been accomplished successfully without any severe failure preventing the device operation and plasma experiments. The commissioning is classified into four steps: vacuum commissioning, cryogenic cool-down commissioning, magnet system commissioning, and plasma discharge.Vacuum commissioning commenced after completion of the tokamak and basic ancillary systems construction. Base pressure of the vacuum ...
