Human plasma platelet-activating factor acetylhydrolase (PAF-AH) is a phospholipase A(2) that is primarily associated with low density lipoprotein (LDL). PAF-AH activity has also been found in high density lipoprotein (HDL), although it has recently been indicated that there is no PAF-AH protein in HDL. Plasma paraoxonase 1 (PON1) is an HDL-associated(More)
Background:The significance of BRAF mutations, microsatelite instability (MSI) status and cyclin D1 expression in patients with metastatic colorectal cancer (mCRC) was evaluated.Methods:Primary tumours from 144 patients treated for mCRC were assessed for BRAF (V600E) mutation, MSI status and cyclin D1. The data were correlated with progression-free survival(More)
Patients with renal failure have an increased incidence of atherosclerotic disease. Numerous studies have shown that these patients show increased serum lipoprotein(a) [Lp(a)] concentrations compared with the control population. However, variable alleles at the apolipoprotein(a) [apo(a)] gene locus determine to a large extent the Lp(a) concentration in the(More)
The dysfunction of the immune system has been implicated in the cause of essential hypertension (EH). On the other hand, interleukin- 1beta (IL-1beta) has strongly been involved in the pathogenesis of atheromatosis, whereas our preliminary experiments in serum samples from hypertensive patients before any drug therapy have shown the presence of high(More)
BACKGROUND Stroke is a leading cause of mortality and subsequent serious long-term physical and mental disability among survivors. In the elderly, ischemic stroke accounts for more than 80% of all strokes. OBJECTIVES To identify major risk factors for a first-ever acute ischemic/non-embolic stroke in individuals older than 70 years. METHODS A(More)
OBJECTIVE The significance of dyslipidemia in subclinical hypothyroidism (SH) and the effect of thyroid substitution on lipids remain controversial. The present study aimed to assess the association of SH with lipid abnormalities and to quantify the effect of L-thyroxine therapy on serum lipid profiles. DESIGN Serum lipid parameters of 66 patients with SH(More)
OBJECTIVE Sex hormone-binding globulin (SHBG) is the main transport protein of sex steroids. Recently, it has been found to be produced by granulosa lutein cells, suggesting a local role of SHBG in the ovary. The aim of this study was to investigate whether serum and follicular fluid SHBG levels and SHBG (TAAAA)(n) polymorphism are related to follicle size(More)
Kearns-Sayre syndrome (KSS) is a multisystem mitochondrial disorder characterized by the invariant triad: onset before 20, progressive external ophthalmoplegia and pigmentary retinal degeneration, plus at least one of the following: complete heart block, cerebellar dysfunction and CSF protein >100 mg/dl. Autopsies from patients with KSS revealed widespread(More)
BACKGROUND Epidemiologic studies have shown that serum uric acid is a risk factor of coronary artery disease. In addition to fenofibrate, there is some evidence that atorvastatin may have a hypouricemic action, but the underlying mechanisms remain speculative. METHODS This randomized trial was conducted to investigate the effects of atorvastatin and(More)
Hormonal therapy plays a central role in the overall treatment of breast cancer. Aromatase inhibitors can inhibit the aromatase enzyme system resulting in a reduction of oestrogens. Letrozole is a non-steroidal aromatase inhibitor that effectively blocks aromatase activity without interfering with adrenal steroid biosynthesis. The drug can significantly(More)
