The aim of the present study was to evaluate the recently defined simple insulin sensitivity check index QUICKI (Katz et al. 2000) for insulin resistance diagnostics in common clinical and epidemiological practice. Both the QUICKI (1/log insulin + log glycemia in mg/dL) and HOMA (insulin * glycemia in micromol/L/22.5) indexes were calculated from fasting(More)
I N RECENT YEARS, there has been much progress in the study of body water and its sub-divisions, and yet, little attention has been given to fluid within the lumen of the gut and its possible significance in body water measurements. The very facts that, a) flow of water across the gut-wall is bi-directional (I), b) that labeled water placed within the gut(More)

Obesity is a serious risk factor for insulin resistance leading to diabetes and other disorders. As it is also occurring at ever younger age groups the aim of this study was to compare average levels of the homeostatic indices HOMA and QUICKI in obese compared to healthy children in an effort to find convenient markers for insulin sensitivity in clinical(More)
BACKGROUND Adipocyte-fatty acid binding protein (A-FABP) is a circulating protein expressed in adipocytes and macrophages. Several recent studies demonstrated that A-FABP might be involved in the pathogenesis of metabolic syndrome, particularly in dyslipidaemia, insulin resistance and atherosclerosis. The aim of this study was to investigate the influence(More)
BACKGROUND Excess body weight was shown to be associated with risk of several types of cancer. In the Czech Republic, malignant tumors are the second leading cause of death. The aim of this study was to assess the association between the most frequent types of cancer and obesity. METHODS A case-control study was accomplished, using data from the National(More)
