BACKGROUND Surgical creation of permanent vascular access for haemodialysis leads to considerable haemodynamic changes. They could be implicated in the pathogenesis of access complications, which limit access survival, especially in diabetics. Physiologically, the relation between arterial diameter and blood velocity is maintained by wall shear stress (WSS), which is directly related to both bl...

OBJECTIVES We sought to test the hypothesis that vascular endothelial function is impaired in Behçet's syndrome and reflects increased levels of oxidative stress. BACKGROUND Behçet's syndrome is a multisystem inflammatory disorder commonly complicated by vascular thrombosis and arterial aneurysm formation. The precise mechanisms underlying vascular disease in Behçet's syndrome are not known. ...

OBJECTIVES To determine if menstrual status changed in amenorrheic college runners over a 2-year period and what effect this had on brachial artery flow-mediated dilation. PARTICIPANTS Eighteen athletes first studied in our laboratory 2 years prior were available for follow-up. Nine of the 10 original women with athletic amenorrhea (mean +/- SE, age 21.3 +/- 1.2 yrs), and 9 of the 11 eumenorr...

Aim: To compare brachial artery flow-mediated dilation (FMD) in subjects who use smokeless tobacco, smoke cigarettes, or do not use any tobacco product. Materials and methods: In the study, participants were 35 Maras powder users, 36 cigarette smokers and 30 nontobacco user subjects. Blood samples were collected and hematological parameters and lipid parameters were measured. Homocystein and hs...

The measurement of brachial artery vasodilation in response to a hyperaemic stimulus has been used extensively to assess changes in endothelial function. However, whether or not similar changes occur in response to an active hyperaemic stimulus is unknown. The purpose of the present study was to compare brachial artery vasodilation in response to an active compared with a reactive hyperaemic st...

AIMS To examine the acute effect of red wine and de-alcoholized red wine on endothelial function. METHODS AND RESULTS High frequency ultrasound was used to measure blood flow and percentage brachial artery dilatation after reactive hyperaemia induced by forearm cuff occlusion in 12 healthy subjects, less than 40 years of age, without known cardiovascular risk factors. The subjects drank 250 m...

brachial artery aneurysms are rare but potentially limb threatening condition. the presented case here is a 52-year old male referred to the emergency department complaining a sudden onset and progressive pain with coldness of his right upper extremity during brushing. the right upper extremity was pulseless and three-dimensional computed tomography showed an aneurysm of the proximal right brac...

BACKGROUND Understanding the heritable contribution of vascular measures, from parent to offspring, may aid in risk stratification and atherosclerosis prevention efforts. We hypothesized that measures of vascular structure and function would be heritable in this cohort of parents and their adolescent offspring. METHODS AND RESULTS High-resolution ultrasound scans of the brachial and carotid a...

BACKGROUND The relation between dietary fish intake and brachial artery measures, including brachial artery flow-mediated dilation (FMD), has not been well established across sex and racial-ethnic groups. OBJECTIVE We hypothesized that consumption of nonfried fish and plasma phospholipid measures of long-chain omega-3 (n-3) fatty acids would be positively associated with larger FMD in men and...

The normal aging process of the brachial artery (BA) wall is of specific interest since it is often selected as a model artery in studies of vascular function. With echo-tracking ultrasound, diameter, absolute diameter change, and intima-media thickness (IMT) were registered in 60 healthy subjects, 21-86 yr (30 men), at a proximal, upper third, and distal arterial site along the upper arm. Bloo...
