Foetal heart rate (FHR) monitoring is a proven means of assessing foetal health during the antenatal period. Currently, the only widely available instrumentation for producing these data is based on Doppler ultrasound, a technology that is unsuitable for long-term use. For nearly a century, it has been known that the foetal electrocardiogram (FECG) can be(More)
Doppler ultrasound, ultrasound M-mode analysis, fetal electrocardiography, and fetal magnetocardiography are methods by which the fetal heart can be monitored non-invasively. In this paper, they are evaluated and compared. Customarily, it is solely the fetal heart rate, which is monitored using the Doppler ultrasound technique since it is both simple to use(More)
Low mobility group nuclear proteins extracted from the 0.35 M NaCl non histone proteins of calf thymus chromatin were fractionated by preparative high performance liquid chromatography. The different fractions were characterized by polyacrylamide gel electrophoresis and amino acid analysis.
Ferritin has been shown as being the principal iron storage in the majority of living organisms. In marine species, ferritin is also involved in high-level accumulation of (210)Po. As part of our work on the investigation of these radionuclides' concentration in natural environment, ferritin was searched at the gene and protein level. Ferritin was purified(More)
Vitamin E (alpha-tocopherol) concentrations of plasma, platelets and erythrocytes were determined by HPLC in insulin-dependent (type I) and age-matched non-insulin-dependent (type II) diabetic patients and in two control groups. Plasma alpha-tocopherol levels were significantly increased in diabetic patients compared to control groups. Platelet and(More)
Calf thymus LMG proteins are known to be susceptible to a wide variety of chromatin-associated proteases. We have investigated the use of different inhibitors to protect LMG chromosomal proteins from proteolytic degradation. In this work we have developed a preparative method for the extraction of LMG proteins from purified chromatin which provides an LMG(More)
Recent studies on the bio-accumulation of transuranic elements in marine invertebrates have demonstrated an intracellular concentration of radionuclides in the digestive gland. The present investigation aims to establish the distribution of [241Am] within the different structures of the cell nucleus. Lobsters were experimentally contaminated through feeding(More)
Le phenomene general de la biosynthese de I'ADN au cours de la division cellulaire et au cours de la meiose a fait l'objet de nombreux travaux. Au moyen de techniques diverses, cytophotom6triques et radioautographiques, un grand nombre de rsultats a te obtenu concernant la teneur en ADN des noyaux cellulaires des tissus des metazoaires. En ce qui concerne(More)
