The acid-base balance in 307 Chinese patients in labour was studied in Tsan Yuk Hospital, Hong Kong over a 15-month period. Fifty-six of these were normal cases, 200 cases exhibited clinical signs of foetal distress and the other fifty-one were high risk cases. The results showed that cases of clinical foetal distress had a significantly lower foetal pH than that in the normal control group. Of...

SARS-CoV-2 causes placental changes that can lead to embryonic/foetal death. However, the pregnant woman who in other diseases is considered (e.g., H1N1) a risk group for development of severe forms disease, COVID-19 rarely evolves with severity, except when childbirth occurs, and loses bond placenta.

Foetal well-being during labour is of utmost importance. One of the ways to attempt to assess foetal wellbeing is by recording foetal heart rate (FHR). Loss of variability and deceleration patterns are known to be associated with foetal distress. Decelerations and foetal bradycardia have been described after any type of effective labour analgesia. This review addresses the questions if certain ...

The development of segmentation using foetal ultrasound images is explained. The current paper work explains the development of enhancement and segmentation algorithms as the ultrasound diagnosis highly depends on the quality of the data. Developed algorithms segment the foetus and helps in analyzing the anatomical structure. This makes an easy diagnostic tool for the obstetricians to analyze a...

Haploinsufficiency of SOX9, which encodes a homeodomain transcription factor, results in Campomelic dysplasia. Classical features of this disorder (e.g. skeletal dysplasia and 46,XY sex reversal) are in concordance with SOX9 expression profiles during human embryonic development. We report the robust expression of SOX9 throughout the pancreas during human embryogenesis, at levels of detection e...

Stereological studies were performed on 20 pairs of adrenal glands of human foetuses. The volume of particular adrenocortical zones, average cell volume and number of parenchymal cells were calculated. In 50 to 320 mm crown-rump length (C.-R.L.) foetuses (9-38 weeks of the intra-uterine life) an exponential increase in adrenal gland weight was found. If compared with the earlier period, the rat...

In farm animals (bovine, ovine, swine, rabbit and poultry), muscle fibre characteristics play a key role in meat quality. The present review summarises the knowledge on muscle fibre characteristics and ontogenesis in these species. Myofibre ontogenesis begins very early during embryonic life, with the appearance of two or three successive waves of myoblasts which constitute the origin of the di...

1. Glycolysis by the supernatant fraction of homogenates of liver from guinea pigs and rats at various stages of development (foetal, newborn and adult) has been examined in a suitably fortified medium by measurement of inorganic phosphate uptake and production of lactate and glycerol 1-phosphate. 2. Starting with glucose as substrate, two rate-determining steps in glycolysis occur at the stage...
