BACKGROUND Normal pregnancy is associated with enhanced vasodilatation because of the increased nitric oxide (NO) production. Because L-homoarginine can act as a substrate for NO production, concentrations of L-homoarginine in normal pregnancy were assessed in the present study to test whether L-homoarginine is associated with endothelial function.

The paper considers the intensity modulated radiation therapy (inverse) treatment planning. An approach to determine the trajectories of the leaves of the multileaf collimator (MLC) in order to produce the prescribed intensity distribution is developed. The paper concentrates on the multiple static delivery technique. A mathematical model for calculating(More)
BACKGROUND We evaluated the arrhythmogenic potential of hypoglycemia by studying electrocardiographic (ECG) changes in response to hyperinsulinemic hypoglycemia and associated sympathoadrenal counterregulatory responses in healthy subjects. METHODS The study population consisted of 18 subjects, aged 30-40 years. Five-minute ECG recordings and blood(More)
BACKGROUND The purpose of the present study was to investigate pregnancy-related changes in the maternal serum lipid profile and endothelial function. METHODS AND RESULTS As part of the population-based, prospective cohort Cardiovascular Risk in Young Finns study conducted in Finland, 57 pregnant Finnish women and 62 control women matched for age and(More)
We evaluated whether the use of cartilage thickness measurement would improve the ability of the arthroscopic indentation technique to estimate the intrinsic stiffness of articular cartilage. First, cartilage thickness and ultrasound reflection from the surface of bovine humeral head were registered in situ using a high-frequency ultrasound probe.(More)
BACKGROUND Our objective was to investigate whether serum concentrations of asymmetric dimethylarginine (ADMA) or l-arginine correlate to hyperlipidemia or endothelial function in normal pregnancy compared with the non-pregnant subjects. METHODS AND RESULTS As a part of population-based, prospective cohort Cardiovascular Risk in Young Finns study(More)
Structural alterations associated with early, mostly reversible, degeneration of articular cartilage induce tissue softening, generally preceding fibrillation and, thus, visible changes of the cartilage surface. We have already developed an indentation instrument for measuring arthroscopic stiffness of cartilage with typical thickness >2 mm. The aim of this(More)
BACKGROUND Traditional risk factors such as hyperlipidemia induce a state of inflammation that impairs vascular function. Despite marked maternal hyperlipidemia, endothelial function improves during pregnancy. In non-pregnant state increased circulating levels of pro-inflammatory cytokines and high sensitive C-reactive protein (hsCRP) lead to attenuated(More)
We investigated the effect of plant stanol esters (STAEST) on serum total and LDL cholesterol concentrations and endothelial function in subjects with type 1 diabetes (T1D). In addition, the changes in the relative serum markers of cholesterol metabolism were recorded. In a parallel, randomized, double-blind study the intervention group (n = 11) consumed(More)
We investigated the effects of stanol (STAEST) and sterol esters (STEEST) on endothelial function in hypercholesterolemic subjects. In addition, associations of variables of cholesterol metabolism with endothelial function were investigated. In a double-blind randomized cross-over study (n=39) with age-matched parallel control group (n=37) the subjects(More)
