Background. The local effect of coronary angioplasty is evaluated on the basis of postangioplasty angiograms. Smooth-walled dilation is considered to represent minimal or no injury, whereas intraluminal haziness corresponds with wall laceration. This study correlates the preangioplasty and postangioplasty angiograms with the histopathology of the target sites. Methods and Results. The study inc...

A method has been developed for routine high yield separation of canalicular (cLPM) from basolateral (bILPM) liver plasma membrane vesicles of rat liver . Using a combination of rate zonal floatation (TZ-28 zonal rotor, Sorvall) and high speed centrifugation through discontinuous sucrose gradients, 9-16 mg of cLPM and 15-28 mg of bILPM protein can be isolated in 1 d . cLPM are free of the basol...

Background Childbirth and puerperium are of the most important periods in women's lives and can affect different aspects of their lives. Objective To determine the effect of perineal massage in the second stage of labor on perineal lacerations, episiotomy, and perineal pain in nulliparous women. Methods This randomization clinical trial was conducted at Be'sat Hospital in Sanandaj, Iran, fr...

A 39-year-old otherwise healthy woman presented to thehospitalwith acute cholecystitis andunderwent a laparoscopic cholecystectomy. The procedure was technically difficult due to a severely inflamed gallbladder with adherent omentum. There was poor visualization of the cystic duct and bile duct junction, and a subtotal cholecystectomy was carried out. A surgical drain was left at the previous g...

SUMMARY Conventional imaging protocols are unable to visualize the intraforaminal/canalicular segments of the lower cranial nerves (IX-XII). On the basis of previous successful demonstration of individual cranial nerves within the cavernous sinus by constructive interference in steady-state MR imaging, we describe the use of contrast-enhanced 3D fast imaging employing steady-state acquisition M...
