background: vascular access (va) is an important aspect for blood circulatory in hemodialysis (hd). arteriovenous fistula (avf) is a suitable procedure to gain va. maturation of the avf is a status of avf, which can be cannulated for hd. this study aimed to discover the parameters that effectively reduce the duration between va and start of hd, which symbolizes the maturation time (mt).   metho...

purpose : to determine the association between retinal vascular diameter and its branching angles with diabetic retinopathy (dr) stages in diabetic patients methods : a descriptive analytic cross-sectional study was conducted in 62 diabetic patients (120 eyes) referred to farabi eye hospital between june 2008 and december 2009. digital fundus photography pictures were imported into photoshop so...

Background: Vascular Access (VA) is an important aspect for blood circulatory in Hemodialysis (HD). Arteriovenous Fistula (AVF) is a suitable procedure to gain VA. Maturation of the AVF is a status of AVF, which can be cannulated for HD. This study aimed to discover the parameters that effectively reduce the duration between VA and start of HD, which symbolizes the maturation time (MT). &nbs...

uniaxial compressive strength (ucs) and elastic properties of rocks play a major and vital role for the design of any engineering structure. the specimen diameter size is one of the main factors that influencing on ucs, elasticity modulus and poisson’s ratio (e and υ). here, an attempt has been made to investigate the effect of specimen diameter size on ucs, e and υ. moreover, we studied the co...

OBJECTIVES This study sought to evaluate the incidence, impact, and predictors of vascular complications in transcatheter aortic valve implantation (TAVI). BACKGROUND Vascular complications increase morbidity and mortality in transfemoral TAVI; however, there remains a paucity of data describing these serious events. METHODS We performed a prospective cohort study of 130 consecutive transfe...

BACKGROUND Vascular complications after transfemoral transcatheter aortic valve replacement are common and associated with significant morbidity and mortality. Little is known about the effect of access approach on vascular complications. METHODS AND RESULTS Between 2007 and 2013, 331 patients underwent transfemoral transcatheter aortic valve replacement via open surgical (OS) or fully percut...

BACKGROUND AND PURPOSE Few and conflicting data exist on the case fatality rate in stroke patients with basilar artery dolichoectasia. We analyzed basilar artery characteristics (diameter, height of bifurcation, transverse position) and 5-year mortality (all-cause, nonstroke vascular, and stroke) in patients with brain infarction. METHODS The basilar artery diameter was measured with a 16-dio...

Urtica dioica L. is an Iranian native pharmacological plant for which little attention has been paid to the anatomical structure. Medical applications of this plant include diabetes therapy, digestive improvement, anemia and kidney disease therapy. Because climatic conditions can affect the anatomical structure which in turn affects pharmacological compositions, research on the anatomy of this ...
