1. Describe the factors that modulate the transition of pulmonary circulation from in utero to after birth. 2. Delineate temporal changes in pulmonary vascular resistance during fetal life. 3. List the substances that play a role in vasoregulation of normal fetal pulmonary circulation. 4. Delineate the role of nitric oxide in increasing pulmonary blood flow at birth. 5. Describe the common phys...

Forty two years I've been in the ministry. Seen a lot of things. Do you know what I've noticed? Christianity is trendy. Especially in this country where everyone follows the winds of change to exploit change. Here is what I've noted. 1. Crusades and mass meetings: These were in the 50's and 60's. (Before me, mind you.) Billy Graham made them famous but this was the American means of educational...

The normal pregnant woman and the newborn infant both have raised hormonal iodine levels (Rose, Russell, and Starr, 1963; Pickering et al., 1958). The very early fetus has a low hormonal iodine which rises as gestation proceeds, but the level in premature babies is still lower than that of full-term infants (Andreoli and Robbins, 1962; Rose et al., 1963; Marks and Man, 1965). The serum protein-...

Previous studies have shown that bile salt concentrations in human blood taken from the placenta at birth of term infants are in the range found in adults. A 125I-radioimmunoassay procedure and capillary gas liquid chromatography-mass spectrometry have been used in this investigation to measure serum bile salt concentrations in premature and normal term infants. It was found that the serum bile...

Spontaneous intestinal perforation (SIP) of the newborn is a single commonly found in terminal ileum without distinct causes. These cases often associated with prematurity. The new COVID-19 pregnancy increased risk premature rupture membranes, preterm delivery, intrauterine fetal death (IUFD), and low birth weight (LBW). Here we report twin SIP that was born from Coronavirus-19 positive mother....

Objective. To investigate whether prophylactic surfactant administration is superior over selective treatment in preterm infants with respiratory distress syndrome (RDS). Methods. In our retrospective analysis, we compared premature infants (23 + 0 to 26 + 6 weeks) receiving 200 mg/kg surfactant (curosurf(®)) within five minutes after birth (prophylactic group, N = 31) with those infants who re...

Bradykinin is largely inactivated in one passage through the pulmonary vascular bed of adult animals. We studied pulmonary inactivation of bradykinin in newborn lambs, fetal lambs at term, fetal lambs preterm, and adult ewes by comparing the systemic pressure response to infusions proximal to the pulmonary vascular bed with the response to infusions distal to the pulmonary vascular bed. A high ...

This study was undertaken in Gaza, Palestine, in a cohort of babies born in 2011. Hair samples of newborns were analyzed for metal load by DRC-ICP-MS. We report specific level of contamination by teratogen/toxicants metals of newborn babies, environmentally unexposed, according to their phenotypes at birth: normal full term babies, birth defects or developmentally premature. The occurrence of b...

introduction: preterm birth is still a major health problem throughout the world, which results in 75% of neonatal mortality. preterm labor not only inflicts financial and emotional distress, it may also lead to permanent disability. the present study was conducted to determine the related risk factors and preventive measures of preterm labor. methods: this retrospective cross-sectional study a...
