OBJECTIVE To date, the contribution of basal atrial natriuretic peptide (ANP) levels to resting vascular function in humans is unknown. In the present study we sought to investigate the role of ANP in regulating regional vascular volume and venous tone in healthy subjects. METHODS AND RESULTS We used radionuclide plethysmography to examine the effects of ANP and the ANP-receptor antagonist A7...

BACKGROUND Radial forearm free flap is the most reliable flap for intraoral soft tissue reconstruction after cancer ablation surgery. However, unesthetic scar of the donor site and the need for a second donor site for skin graft are major disadvantages of the forearm flap. The purpose of this study was to report the clinical results of double-layered collagen graft to the donor site of the fore...

BACKGROUND It has been proposed that under hypoxic conditions, nitrite may release nitric oxide, which causes potent vasodilation. We hypothesized that nitrite would have a greater dilator effect in capacitance than in resistance vessels because of lower oxygen tension and that resistance-vessel dilation should become more pronounced during hypoxemia. The effect of intra-arterial infusion of ni...

There is evidence that hyperinsulinemia may stimulate endothelin-1 (ET-1) generation or release, which may affect diabetic vascular complications. BQ-123, a specific ET(A) receptor antagonist, was used to investigate if insulin-induced vascular effects are influenced by an acute ET-1 release. Two randomized, placebo-controlled, double-blind, cross-over studies were performed. In protocol 1, 12 ...

introduction: height is an important biological human characteristic in anthropological studies and forensic medicine. in this way, forearm length (fal) can be a useful factor for the height prediction in different population. the goal of this study was to find the relation between fal and height in natives of kerman. methods: in a cross-sectional study, 150 cases including 75 males and 75 fema...

BACKGROUND Normalization of brachial artery flow-mediated dilation (FMD) to individual shear stress area under the curve (peak FMD:SSAUC ratio) has recently been proposed as an approach to control for the large inter-subject variability in reactive hyperemia-induced shear stress; however, the adoption of this approach among researchers has been slow. The present study was designed to further ex...

OBJECTIVE To compare the performance on the detection of the invisible veins between our modified prototype device and an existing device in elderly hospitalized patients. METHODS A prospective, cross-sectional, and observational study was performed in the invisible veins in elderly patients. The major variables, skin color near the invisible veins, and diameter and depth of the invisible vei...

AIMS The ultrasonographic (US) evaluation of the median nerve at the level of the carpal tunnel outlet (CTO) and mid forearm in pediatric patients with mucopolysaccharidosis type II (MPS II) and comparison with healthy subjects. MATERIAL AND METHOD Fifteen children with MPS II and 44 healthy children were included in the study and they were divided into three age groups. The cross-sectional a...
