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...

BACKGROUND Previous epidemiological investigations of associations between dietary glycemic intake and insulin resistance have used average daily measures of glycemic index (GI) and glycemic load (GL). We explored multiple and novel measures of dietary glycemic intake to determine which was most predictive of an association with insulin resistance. METHODS Usual dietary intakes were assessed ...

In this article we state a relation between the Kirchhoff and Wiener indices of a simple connected graph G and the Kirchhoff and Wiener indices of those subgraphs of G which are induced by its blocks. Then as an application, we define a composition of a rooted tree T and a graph G and calculate its Kirchhoff index in terms of parameters of T and G. Finally, we present an algorithm for computing...

UNLABELLED Summay: BACKGROUND Insulin resistance is an important pathogenic factor in type 2 diabetes patents. An easy and efficiency measurement predicting insulin resistance; which can be done easily by type 2 patients is desired. OBJECTIVE To examine whether waist circumference is a better predictor of insulin resistance in type 2 diabetes than body mass index (BMI). METHODS From a pop...

Hemodynamic responses to 100% oxygen inhalation were examined in seven anemic children (hemoglobin 1.9 to 3.8 g/100 ml blood; hematocrit 9 to 14%). During air breathing mean values for cardiac index were 7.71 L/min/m2, for heart rate 129/min, for stroke index 61.7 ml/m2, and for systemic vascular resistance 11.5 R.U. Oxygen administration significantly decreased mean values of cardiac index to ...

BACKGROUND/AIMS Hypertensive nephroangiosclerosis is associated with progressive increase of intrarenal vascular resistance. In addition to blood pressure, other factors can contribute to hypertensive renal damage including a prothrombotic state. We investigated the relationship between hemostatic markers and intrarenal vascular resistance in hypertension. METHODS In 115 untreated, nondiabeti...

Passive range of motion exercise is a very common physical therapy treatment for patients admitted to an intensive care unit. However is the knowledge scarce regarding its impact on blood circulation in the extremities. The objective of this study was therefore to investigate the effect of passive range of motion on arterial peripheral leg blood flow velocity (BFV) and vascular resistance. A cr...

The metabolic syndrome shows a variable prevalence in obstructive sleep apnoea (OSA), and its association with insulin resistance or excessive daytime sleepiness in OSA is unclear. This study assessed the following in consecutive patients with newly diagnosed OSA: 1) the prevalence of metabolic syndrome; and 2) its association with insulin resistance and daytime sleepiness. Metabolic syndrome (...

OBJECTIVES This study evaluates the clinical impact of adjusting the loading dose of clopidogrel according to vasodilator-stimulated phosphoprotein (VASP) index in patients with clopidogrel resistance undergoing percutaneous coronary intervention (PCI). BACKGROUND Clopidogrel resistance plays a key role in ischemic recurrence after PCI. In vitro tests of clopidogrel resistance can accurately ...
