We employed next-generation RNA sequencing (RNA-Seq) technology to determine the influence of obesity on global gene expression in skeletal muscle feed arteries. Transcriptional profiles of the gastrocnemius and soleus muscle feed arteries (GFA and SFA, respectively) and aortic endothelial cell-enriched samples from obese Otsuka Long-Evans Tokushima Fatty (OLETF) and lean Long-Evans Tokushima O...

BACKGROUND Whereas visceral fat accumulation (VFA) is related to insulin resistance and atherosclerosis in both haemodialysis (HD) patients and the general population, little is known about the role of subcutaneous fat accumulation (SFA). The purpose of the present study was to examine and confirm the relationship between abdominal fat accumulation (AFA) and various clinical parameters in HD pa...

OBJECTIVES Superficial femoral artery (SFA) involvement in Takayasu arteritis (TAK) has rarely been reported. The purpose of this study was to investigate the clinical characteristic and clinical outcomes of endovascular therapy in such patients. METHODS We analysed the data collected from 105 consecutive patients with TAK, who were diagnosed from January 2011 to December 2013. All patients u...

We tested the hypothesis that endothelium-dependent dilation in soleus muscle feed arteries (SFA) is impaired by aging due to attenuated nitric oxide (NO)-mediated vasodilation. SFA were isolated from young (4 mo) and old (24 mo) male Fischer 344 rats and cannulated with two glass micropipettes for examination of endothelium-dependent [flow or acetylcholine (ACh)] and endothelium-independent [s...

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...

BACKGROUND Endothelial dysfunction is a key factor in the development of atherosclerosis. Commonly, endothelial function is determined in the brachial artery, whereas patients with peripheral artery disease (PAD) present with lower limb atherosclerosis. We hypothesized that in PAD, a segmental or local association exists between endothelial dysfunction and atherosclerotic structural changes. ...

This paper takes issues with the appropriateness of applying the stochastic frontier analysis (SFA) technique to account for environmental effects and statistical noise in the popular three-stage data envelopment analysis (DEA). A correctly specified SFA model with a censored dependent variable and the associated maximum likelihood estimation (MLE) are proposed. The simulations show that the fi...
