The experiment involved observations of 2,514 Holstein-Friesian cows to determine the effects of environmental factors (cow's age, calving season, weight and sex of calves, housing system) and genetic factors on gestation length in dairy cattle and the correlation between gestation length and other reproductive traits (calving ease, stillbirth rates and placental expulsion). Genetic parameters ...

OBJECTIVE To describe the outcome of labour, signs of life at birth, and duration of survival after delivery at 20-23 weeks gestation. DESIGN An observational study using data from the Confidential Enquiry into Stillbirths and Deaths in Infancy 1995-2000. SETTING All deliveries to mothers resident in Trent Health Region. PATIENTS 1306 babies delivered at 20-23 weeks gestation. RESULTS T...

This study evaluated the role of anterior lens capsule vascularity in assessing gestation in small for gestational age (SGA) neonates in a prospective manner. Neonates with birth weight less than 2000 g were recruited. Those with gross congenital malformations, including corneal opacity or cataract and evidence of TORCH infection were excluded from the study. A total of 139 subjects were enroll...

The effect of prepubertal feed level on growth and reproductive development of gilts was investigated. At 13 wk. of age, white crossbred gilts were penned individually and assigned to the following treatments: Ad lib, ad libitum intake from 13 to 25 wk. of age (n = 64); Control, ad libitum intake from 13 wk. of age until 100 kg BW and then 90% of ad libitum intake until 25 wk. of age (n = 65); ...

conclusions approximately one quarter of premature neonates had early mortality, which can be predicted by low gestational age, low birth weight, low apgar score, need to intensive supports, postpartum complications, multiple gestation and history of maternal illnesses. objectives we aimed to determine mortality rate and its main indicators among premature neonates in our region with the aim of...

Introduction Preterm birth is still a major health problem throughout the world. Preterm birth results in 75% of neonatal mortality. We sought to identify risk factors which cause preterm birth. Materials and Methods This cross-sectional study assessed all preterm neonates born in Asali Hospital in Khorram Abad (either by NVD or C/S) during the first 6 months of 2007. Sampling method was censu...

INTRODUCTION The duration of human pregnancy is arbitrarily taken as 280 days (40 weeks). Foetuses are considered to be at high risk once pregnancy goes beyond the expected date of confinement. This study was carried out with the aim of determining the mean gestation age of low-risk pregnancies that went into spontaneous labour and the incidence of adverse outcomes in relation to gestation. M...

BACKGROUND Tracheal occlusion (TO) stimulates lung growth in fetuses affected with congenital diaphragmatic hernia (CDH) although the processes involved in lung maturation still remain unknown. The objective of this study was to evaluate the metabolomic profile of amniotic fluid (AF) following TO in fetal lamb model in order to obtain an indirect view of mechanisms involved in pulmonary reversa...

TonEBP/NFAT5 (the tonicity-responsive enhancer binding protein/nuclear factor of activated T cells) modulates cellular response to osmotic changes by accumulating inositol and sorbitol inside the cells. Our objective was to assess placental osmolytes, TonEBP/NFAT5 RNA and protein expression, and signaling molecules across gestation between control and intrauterine growth restriction (IUGR) ovin...

Estimating gestational age in resource-limited settings is prone to considerable inaccuracy because crown-rump length measured by ultrasound before 14 weeks gestation, the recommended method for estimating gestational age, is often unavailable. Judgements regarding provision of appropriate obstetric and neonatal care are dependent on accurate estimation of gestational age. We determined the acc...
