Invariant features of temporally varying signals are useful for analysis and classification. Slow feature analysis (SFA) is a new method for learning invariant or slowly varying features from a vectorial input signal. It is based on a nonlinear expansion of the input signal and application of principal component analysis to this expanded signal and its time derivative. It is guaranteed to find ...

Spike frequency adaptation (SFA) exists in many types of neurons, which has been demonstrated to improve their abilities to process incoming information by synapses. The major carrier used by a neuron to convey synaptic signals is the sequences of action potentials (APs), which have to consume substantial metabolic energies to initiate and propagate. Here we use conductance-based models to inve...

BACKGROUND Most of the folic acid sources are rich also in potassium. Patients with chronic kidney disease (CKD) usually receive a low potassium diet. We investigated the possibility of an association between low potassium diet and folic acid deficiency. METHODS In total, 128 CKD patients participated in this cross-sectional study. Sixty-four patients with CKD grades 1 and 2 were on an unrest...

Objective: The present study sought to investigate the associations of total n-3 fatty acid and SFA intakes with insulin resistance in a Canadian First Nation sample at risk for type 2 diabetes. Design: Fasting values for glucose and insulin were used to estimate insulin resistance by homeostasis model assessment (HOMA-IR). Intakes of n-3 fatty acids and SFA were computed from dietary food and ...

The objectives of the present study are to describe the dietary sources of total fat and of saturated fatty acids (SFA) and to formulate food-based dietary guidelines for SFA in Belgian adolescents. A random sample of 13-18-year-old adolescents was drawn from secondary schools in the region of Ghent. A 7 d estimated food record method was used to quantify nutrient and food intake. The average d...

Background—The clinical significance of magnetic resonance–imaged plaque characteristics in the superficial femoral artery (SFA) is not well established. We studied associations of the ankle-brachial index (ABI) and leg symptoms with MRI-measured plaque area and percent lumen area in the SFA in participants with and without lower-extremity peripheral arterial disease (PAD). Methods and Results—...

BACKGROUND Visceral fat plays a central role in the development of metabolic syndrome and atherosclerotic cardiovascular diseases. The association of visceral fat accumulation with cardio-metabolic diseases has been reported, but the impact of visceral fat on the gene expression profile in peripheral blood cells remains to be determined. The aim of this study was to determine the effects of vis...

OBJECTIVES The aim of this prospective registry was to evaluate the safety and efficacy at 2-year follow-up of the use of drug-eluting balloons (DEBs) for the treatment of superficial femoral artery (SFA) in-stent restenosis (ISR). BACKGROUND The use of DEBs for the treatment of SFA ISR is associated with a satisfactory primary patency rate at 1 year, but no data are available for longer foll...

Since the 1960s, clinical and animal studies have shown that reduction of dietary saturated fatty acid (SFA) consumption is associated with reduced risk of cardiovascular disease (CVD). Thus, reduction of SFA intake is now one of the central strategies of dietary recommendations to reduce CVD worldwide. For example, the World Health Organization and the US Dietary Guidelines recommend dietary c...

Milk products are an important component of human diets, with beneficial effects for health, but also one the major sources nutritionally undesirable saturated fatty acids (SFA). Recent discoveries showing importance rumen microbiome on dairy cattle metabolism and performance highlight that milk composition, potentially SFA content, may be associated microorganisms, their genes activities.
