Statistical tables including 50 and 95 percentile ranges are presented of the combined kidney weights compared with body weight, crown-rump length, and gestation age of foetuses and newborn children, and also a table of kidney weights related to post-natal age. The importance of relating kidney weight to more than one general body criterion in the perinatal period is illustrated.

OBJECTIVE It was the aim of this study to examine the potential value of cervical length at 11-13 weeks' gestation in the prediction of spontaneous preterm delivery. METHODS This was a screening study for spontaneous preterm delivery in singleton pregnancies from cervical length measured by transvaginal ultrasound at 11-13 weeks' gestation. The performance of screening for preterm delivery by...

The experiment measured lamb responses to supplementation of the pregnant ewe diet with vitamin E above requirement. Crossbred ewes were mated with either Suffolk or Texel rams. Twin-bearing ewes were randomly allocated (approximately 21 months of age at allocation) to one of four treatment groups (20 ewes per group, 10 mated with Suffolk and 10 with Texel rams). Treatments imposed were 50, 100...

OBJECTIVE To determine the feasibility of correctly identifying fetal gender from 11 to 14 weeks' gestation. METHODS A prospective cross-sectional study in a university Department of Obstetrics and Gynaecology, London. A total of 524 women from an unselected population underwent a detailed assessment of fetal anatomy at 11-14 weeks of gestation (confirmed by crown-rump length) by means of tra...

FETAL: designates a period intra-uterine development that begins when the product of conception reaches a crown-rump length of 30 mm, usually by 55 or 56 days after fertilization, and ends at the moment of birth. The product of conception during this period is called a fetus. The period before fetal is embryonic, and the product of conception during that earlier period is termed an embryo. Form...

In this research study, to investigate teratogenic effect of intravitreal injection of bevacizumab in pregnant rat model, twenty seven female Wistar rats were inseminated. Pregnant rats were divided into 6 groups (three groups as case and three as control groups). Each case and control groups were divided according to the day of intravitreal injections (day 2, 10 and 18). Rats in the case group...
