abstract background: it has been demonstrated that noscapine, an antitussive opioid alkaloid, could antagonize bradykinin- induced responses such as bradykinin effects in guinea-pig ileum, cough induced by bradykinin receptor agonist and angiotensin converting enzyme inhibitors, and brain damage after brain edema both in neonatal rat model and in patients with stroke. in the present study, the ...

conclusion our study revealed that the hypoplastic umbilical artery group’s non-dominant cia had higher ri values than the contralateral dominant cia. results eleven of the 165 patients (6.7%) demonstrated a hypoplastic umbilical artery. second-trimester us showed median dominant and non-dominant cia pi values of 1.43 and 1.60 (p = 0.062), respectively, and median dominant and non-dominant cia ...

Background: Abnormal umbilical cord pH can be indicated a distress imposed of newborn and can also be useful in determining the prognosis of the newborn. There are different views about the effect of the neonatal delivery method on the blood gas analysis of the umbilical artery. This study aimed to determine the effect of the method of delivery on umbilical artery pH. Methods: In this Cross ...

PURPOSE To explore the effect of pulsatile flow in the decellularization process of small blood vessels. METHODS A total of 30 human umbilical cords were used in the current study. The umbilical cords were flushed with 0.25% trypsin/0.01% EDTA for 30 minutes, followed by treatment with 1% sodium dodecyl sulfate sodium dodecyl sulfate for 3 hours. The effectiveness of decellularization on the ...

Human umbilical arteries are unique vessels in that they close quickly and completely at birth. It has been suggested that cyclic uanosine 3',5'-monophosphate (cAMP) in relaxation. This hypothesis has been evaluated in term gestational human umbilical artery segments incubated at 37 degrees C and in room air. (a) The basal cGMP content (1 pmol/mg protein) of artery segments incubated in room ai...

background: fetal color doppler is important for evaluation of hypoxia in intrauterine growth restriction (iugr) fetus. objective: in this study we compare fetal and maternal color doppler with blood gas analysis to detect fetal acidosis. materials and methods: in this cross-sectional study we evaluated 100 hospitalized patients with iugr for comparison of color doppler results with arterial bl...

background: doppler indices of umbilical artery are used as indicator of fetal well being. objective: to compare doppler parameters of umbilical artery including pulsatility index (pi) and resistance index (ri) in patients with preeclampsia with those of normal pregnancies and to evaluate the diagnostic characteristics of these parameters in preeclampsia. materials and methods: in a case contro...

The aim of this study was to determine the first trimester human peripheral arterial and venous blood flow between 5 - 10 weeks of gestation. Two hundred twenty four women with singleton, uncomplicated pregnancies were prospectively studied with transvaginal ultrasound. Ductus venosus, umbilical artery waveforms and pulsatility indexes (PI) were assessed as well as the waveform of the umbilical...
