BACKGROUND/AIMS We investigated the associations among body mass index (BMI), insulin resistance, and β-cell function in Korean patients newly presenting with type 2 diabetes. METHODS In total, 132 patients with new-onset type 2 diabetes mellitus were investigated. A standard 75-g oral glucose tolerance test was performed, and the indices of insulin secretion and insulin resistance were calcu...

INTRODUCTION Eugene Garfield laid one of the key empirical foundations for modern information science through the innovation of the citation indexing of science. He created the impact factor as part of the process of developing the Science Citation Index (SCI) produced by his company, the Institute for Scientific Information (ISI). In determining the coverage of this index, Garfield utilized tw...

PRINCIPLES Small dense LDLs have been found to be associated with type 2 diabetes (T2DM). This association has been observed in the context of decreased HDL cholesterol and increased triglycerides. METHODS In the present study the relationship between LDL particle size and insulin sensitivity was assessed in 46 patients with T2DM (mean age 60 (11) years, HbA1c 7.6 (0.8) %). 75 g oral glucose ...

We tested the hypothesis that regular endurance exercise prevents the age-related decline in insulin action typically observed in healthy, sedentary adults. An index of whole body insulin sensitivity (ISI), obtained from minimal model analysis of insulin and glucose concentrations during a frequently sampled intravenous glucose tolerance test, was determined in 126 healthy adults: 25 young [27 ...

Citation analysis is performed in order to evaluate authors and scientific collections, such as journals and conference proceedings. Currently, two major systems exist that perform citation analysis: Science Citation Index (SCI) by the Institute for Scientific Information (ISI) and CiteSeer by the NEC Research Institute. The SCI, mostly a manual system up until recently, is based on the notion ...

The world-wide and multidisciplinary Science Citation Index (SCI), available presently online as SCI Expanded via Web of Science from the Institute for Scientific Information (ISI) in Philadelphia, has been applied as a powerful and reliable tool for the comprehensive study of citation patterns (GARFIELD 1979). Introductory bibliometric analyses for sedimentological literature were already pres...

Cardiovascular disease is a prevalent and serious complication after solid organ transplantation. Treatment with glucocorticoids is associated with increased risk for diabetes mellitus, insulin resistance, weight gain, hypercholesterolemia, and hypertension, all shown to be independent risk factors for cardiovascular disease. We sought to test the hypothesis that tapering of prednisolone (TAP) ...

AIMS To examine the magnitude of thromboplastin and coagulometer interactions on the precision of International Normalised Ratio (INR) values when the manufacturers' recommended instrument specific International Sensitivity Index (ISI) values are adopted for the INR calculation. METHODS The variability of INR values obtained from four automated phototopical coagulometers frequently used in No...
