OBJECTIVES We studied associations of magnetic resonance imaging (MRI)-measured superficial femoral artery (SFA) occlusions with functional performance, leg symptoms, and collateral vessel number in peripheral artery disease (PAD). We studied associations of collateral vessel number with functional performance in PAD. BACKGROUND Associations of MRI-detected SFA occlusion and collateral vessel...

Our goals were to determine the nature of endothelium-dependent and -independent vascular responses in isolated soleus feed arteries (SFA) and to test the hypothesis that these responses would be altered by exercise training. Exercise-trained rats ran 30 m/min, up a 15% grade, 1 h/day, 5 days/wk for 10-12 wk, while sedentary control rats were confined to normal cage activity. SFA were isolated,...

T he superficial femoral artery (SFA) lies largely within the adductor canal, where it is surrounded by a double layer of fascia of the firm muscles of the thigh. After passing the adductor hiatus, the termination of the adductor canal, the SFA becomes known as the popliteal artery and enters the soft fatty tissue of the popliteal fossa. The SFA is hypothesized to undergo dramatic nonpulsatile ...

Recommendations limiting the intake of total fat, SFA, MUFA and PUFA have been established in several countries with the aim of reducing the risk of chronic diseases such as CVD. Studies have shown that intakes of total fat and SFA are above desired recommended intake levels across a wide range of age and sex groups. In addition, intakes of PUFA and MUFA are often reported to be less than the d...

We tested two hypotheses, first that exercise training reverses age-related decrements in endothelium-dependent dilation in soleus muscle feed arteries and second that this improved endothelium-dependent dilation is the result of increased nitric oxide (NO) bioavailability due to increased content and phosphorylation of endothelial NO synthase (eNOS) and/or increased antioxidant enzyme content....

1) In univariate analyses of population-based observational data, are there direct relations of dietary SFAs to CHD? 2) In multivariate analyses controlled for possible confounders, are there independent direct relations of dietary SFAs to CHD? 3) Is the SFA-CHD relation similar for ‘‘hard’’ fatal CHD and ‘‘soft’’ total CHD? 4) Do limitations in quality of dietary data in epidemiologic studies ...

Automatic action recognition in video has a broad array of applications, from surveillance to interactive video games. Classic algorithms usually use handcrafted descriptors such as SIFT (see [5]) or HOG (see [3]) to compute feature vectors of videos, and have achieved promising results in the past (see [7]). More recently, Quoc Le and Will Zou at the Stanford AI lab have proved that ISA featur...

Flow-induced dilation is thought to contribute to dilation of skeletal muscle arteries and arterioles during exercise hyperemia. We sought to determine whether rat soleus feed arteries (SFA) exhibit flow-induced dilation and to evaluate the potential contribution of flow-induced dilation of SFA to exercise hyperemia. Rat SFA were isolated and cannulated to allow pressure and intraluminal flow t...

OBJECTIVES The purpose of this prospective registry was to evaluate the safety and efficacy, at 1 year, of the use of drug-eluting balloons (DEB) for the treatment of superficial femoral artery (SFA) in-stent restenosis (ISR). BACKGROUND The use of the self-expanding nitinol stent has improved the patency rate of SFA after percutaneous transluminal angioplasty (PTA). As the population with SF...
