Rat brown adipocytes at day 22 of foetal development showed greater size, higher mitochondria content and larger amounts of lipids, as determined by flow cytometry, than 20-day foetal cells. Simultaneously, an inhibition on the percentage of brown adipocytes into S+G2/M phases of the cell cycle was observed between days 20 and 22 of foetal development. The expression of several adipogenesis-rel...

It is very difficult to diagnose foetal distress in time. various investigations have been suggested from time to time for determination of intrauterine foetal status. In recent ;years amnioscopic examination to see the physical character of liquor amnii is extensively practised. Saling's (1965) micro-sampling of foetal scalp blood and study of acid-base balance of the 'Same have also raised th...

Treatment with dexamethasone enhanced 3H2O incorporation into liver and blood lipid, and also increased plasma glucose, insulin, non-esterified fatty acid and triacylglycerol concentrations during late gestation in the mother rat. An inverse relationship between glycogen and lipid synthesis in foetal liver and lung was observed in control rats. This relationship was also observed in foetal live...

Previous pyrophosphate-gel studies have reported the existence of embryonic neonatal myosin isoenzymes in human developing muscle. The present investigation was undertaken to characterize their subunit composition more precisely. Two immature muscle myosins are contrasted with adult myosin: neonatal myosin and foetal myosin. The neonatal form of myosin is weakly cross-reactive with rabbit slow ...

Thymosins beta 4 (Tβ4) is a member of the beta-thymosins family, a family of peptides playing essential roles in many cellular functions. Our recent studies suggested Tβ4 plays a key role in the development of human salivary glands and the gastrointestinal tract. The aim of this study was to analyse the presence of Tβ4 in the human adult and foetal genitourinary tract. Immunoloca...

Both an increased rate of embryonic, foetal and perinatal losses, and the occurrence of deviations in foetal and placental development are associated with bovine pregnancies obtained from in vitro produced embryos. This thus requires for a more accurate and frequent monitoring of foetal and maternal functions during pregnancies. Such approaches will enable to establish the period during which t...

Biomedical research in human beings is largely restricted to in vitro studies that lack complexity of a living organism. To overcome this limitation, humanized mouse models are developed based on immunodeficient characteristics of severe combined immunodeficiency (SCID) or recombination activating gene (Rag)(null) mice, which can accept xenografts. Peripheral constitution of human immunity in S...

Numerical simulations of specific absorption rate (SAR) and temperature changes in a 26-week pregnant woman model within typical birdcage body coils as used in 1.5 T and 3 T MRI scanners are described. Spatial distributions of SAR and the resulting spatial and temporal changes in temperature are determined using a finite difference time domain method and a finite difference bio-heat transfer so...
