Lung fluid is reabsorbed rapidly at birth to permit alveolar respiration. We reported previously that expression of aquaporins (AQP) 1, 4, and 5 in rat lung increased just after birth. The hypothesis was tested that the increased AQP expression is associated with increased osmotic water permeability (Pf) between the airspace and capillary compartments. Pf was measured in isolated perfused fetal...
BACKGROUND While both ionizing and nonionizing radiation are known to impair human reproductive capacity, the role of low-level domestic radiation continues to be an unsettled issue. OBJECTIVES We examined the geostatistical distribution (residential longitude and latitude) of orofacial cleft birth cases adjusted for the underlying population distribution. Furthermore, we examined the cleft b...
BACKGROUND Evidence for a relationship between trihalomethane (THM) or haloacetic acid (HAA) exposure and adverse fetal growth is inconsistent. Disinfection by-products exist as complex mixtures in water supplies, but THMs and HAAs have typically been examined separately. OBJECTIVES We investigated joint exposure at the individual level to THMs and HAAs in relation to birth weight in the mult...
Birth traits of 68 Angus and 49 Charolais x Angus calves sired by four Angus and seven Charolais bulls, respectively, were studied. Timed intervals during the calving process were compared between breed of sire groups. The Charolais sired calves required an average of 3.7 rain longer from the first appearance of the water bag until the feet were first visible; 8.1 rain longer (P<.01) from the t...
Background and objective: Although promoting methods to reducing labor pain by health professional is essential, few researches have been addressed to the study of knowledge among these workers. This study aimed to determine knowledge of health professionals of Kashan city regarding water birth and its benefits and barriers in 2015. Methods: This study was cross-sectional design (descriptive-an...
during natural gas processing, water in natural gas may cause to hydrates formation in pipelines which may lead to serious damages to process equipments. given the problems raised by present of water in natural gas, glycol solvent uses to remove water.in contact of glycol with gas always an amount of btex and voc absorb along with water, which on glycol recovery process, these substances separa...
determination of uranium in natural water and complex solutions using ion exchange chromatography: a combined procedure using ion exchange chromatography and uv-vis spectrophotometry techniques has been developed to measure uranum in natural water and complex solutions. after conditicing , one hundred milli liters of sample solutions have been passed through an ion exchange column,pachked with ...
to have an, idea about the relation between the length of birth interval and lactation, and birth control program this study have been done. the material for such analysis was nomad women's fertility history that was in their reproductive period (15-44). the material itself was gathered through a health survey. the main sample was composed of 2,165 qualified women, of whom 49 due to previous or...
We studied a group of women of reproductive age (15-49 years) who were chronically exposed to arsenic through drinking water to identify the pregnancy outcomes in terms of live birth, stillbirth, spontaneous abortion, and preterm birth. We compared pregnancy outcomes of exposed respondents with pregnancy outcomes of women of reproductive age (15-49 years) who were not exposed to arsenic-contami...
