By subjecting A strain eggs at the time of fertilization and polar body extrusion to 5 micrograms/ml cytochalasin B, digynic triploidy was produced in 80% fertilized eggs. Triplonucleate eggs were transplanted to recipients and examined between 9-11th day of pregnancy. Development of triploid mouse embryos up to day 7 is normal and most embryos form early egg cylinder. At day 8 the embryonic pa...

caused no anxiety, but the nurse noticing a sudden change in the patient's appearance, sent for the Resident, Dr Kerr, who, recognising the serious condition, summoned me by telephone. When I saw the patient at 5 p.m. she was collapsed, ashy grey in appearance, and covered with cold, clammy sweat; pulse 128. P.V. cervix barely admitted two fingers, membranes unruptured, slight uterine haemorrha...

OBJECTIVE A history of foetal death is a risk factor for complications and foetal death in subsequent pregnancies as most previous risk factors remain present and an underlying cause of death may recur. The purpose of this study was to evaluate subsequent pregnancy outcome after foetal death and to compare cases of recurrent foetal death. STUDY DESIGN A retrospective cohort study in a tertiar...

For many years intermittent recording of the foetal heart rate with a stethoscope and the detection of meconium in the liquor have been the only signs used for diagnosing intrapartum foetal asphyxia. Although the system has the virtue of simplicity, the unexpected disappearance of foetal heart sound when the foetal heart rate was being recorded as normal, or the frequent delivery of a vigorous ...

• The vessels of the unexpanded foetal lung react more strongly to certain stimuli than those of the expanded foetal or newborn lung; they probably react more strongly than the vessels of adult lungs. Thus acetylcholine and histamine caused profound vasodilatation in unexpanded foetal lungs and comparatively weak dilatation in expanded foetal lungs. Noradrenaline caused a high degree of vasocon...

premature rupture of membranes (prom) is one of the most common complications of pregnancy that has a major impact on neonatal outcomes. with respect to racial, nutritional and cultural differences between developed and developing countries, this study was conducted to detect the prevalence of neonatal complications following prom and the role of the duration of rupture of membranes in producin...

Foetal movements commence at seven weeks of gestation, with the foetal movement repertoire including twitches, whole body movements, stretches, isolated limb movements, breathing movements, head and neck movements, jaw movements (including yawning, sucking and swallowing) and hiccups by ten weeks of gestational age. There are two key biomechanical aspects to gross foetal movements; the first be...

the gas separation performance of commercial ceramic titania and hybrid silica (hybsi®) membranes was assessed using the gas permeation and permporometry methods. results indicated that the hybsi® membranes have a hybrid surface containing regions covered by a polymeric matrix and others with inorganic pores. these membranes have high h2 selectivity, which increases significantly with temperatu...

Cell therapy for nucleus pulposus (NP) regeneration is an attractive treatment for early disc degeneration as shown by studies using autologous NP cells or stem cells. Another potential source of cells is foetal cells. We investigated the feasibility of isolating foetal cells from human foetal spine tissues and assessed their chondrogenic potential in alginate bead cultures. Histology and immun...
