Peripheral artery cannulation is a common procedure but can sometimes be difficult. Our goal was to determine if a median nerve block would increase the diameter and flow of the radial artery. Radial artery diameter and peak velocity was measured using a SonoSite Ultrasound System. Using ultrasound guidance, a median nerve block was performed with lidocaine. Subsequent measurements of the radia...
INTRODUCTION To evaluate the effect of two different post space diameters and related resin cement film thicknesses on the bond strength of a polyfiber post. MATERIALS AND METHODS A total of 48 premolars were randomly divided into two according to the post space diameter: 1.1 mm and 1.5 mm. Then each group was divided into three sub-groups according to luting cement used: RelyX U100, Panavia ...
for several years, researchers in familiarity of efl teachers with post-method and its role in second and foreign language learners’ productions have pointed out that the opportunity to plan for a task generally develops language learners’ development (ellis, 2005). it is important to mention that the critical varies in language teaching was shown is the disappearances of the concept of method ...
Using three-dimensional finite element analysis (3D-FEA), stress distributions in the remaining radicular tooth structure were investigated under the condition of varying diameters of fiber post for fiber post-reinforced composite resin cores (fiber post and core) in maxillary central incisors. Four 3D-FEA models were constructed: (1) fiber post (ø1.2, ø1.4, and ø1.6 mm) and composite resin cor...
OBJECTIVE To evaluate the effects of laparoscopic cystectomy on serum anti-Müllerian hormone (AMH) level as a marker of ovarian reserve in patients with endometrioma. METHODS A prospective observational study enrolled patients aged younger than 40 years who were referred to a tertiary center in Tehran, Iran, between January 1, 2013 and December 31, 2014 to undergo laparoscopic cystectomy for ...
According to the class of hypovolaemic shock, a blood loss less than 750 ml is not associated with the physiological changes. As a result it may cause a delay in fluid resuscitation. We postulate inferior vena cava (IVC) diameter reduction in inspiration and expiration may resemble the significant volume of blood loss in a healthy adult. We conducted a study to examine the changes of the IVC di...
