Arylsulphatases of human placenta
Clinica Chimica Acta, 1964Abstract It has been shown that human placenta contains arylsulphatases hydrolysing 2-hydroxy-5-nitrocatechol sulphate (NCS) as well as p -nitrophenyl sulphate (NPS). This indicates the presence of arylsulphatases A, B and C. Soluble arylsulphatases splitting NCS are found mostly in the extracts of acetone powders prepared from placenta, while the ...

AbstractGangliosides extracted from human placenta were composed of four major components (G1–G4), which were purified by silica beads column chromatography. The structures of these gangliosides were analyzed by exoglycosidase treatments, 400 MHz proton magnetic resonance spectroscopy and gas chromatography‐mass spectrometry and were concluded to be as

Transthyretin and the human placenta
Placenta, 2013Since its discovery, transthyretin (TTR) has been regarded as an important hepatically derived protein carrier of thyroid hormones and retinol in blood. However, in more recent years it has been shown that TTR has other important functions. TTR is abundant in cerebrospinal fluid, where it may be involved in transport of thyroid hormones into the brain.

SINCE their discovery1, lysosomes have been described in many tissues. Here I report the presence of lysosomes characterized by staining with acridine orange2,3 and assays of the concentration and latency of acid phosphatase in the “lysosomal” pellet, in human term placenta.

16-DEHYDROGENASE IN HUMAN PLACENTA
Acta Endocrinologica, 1975ABSTRACT Human placental subfractions were incubated with radioactive oestriol and 16-oxo-oestradiol*. 16-oxo-oestradiol was identified from the oestriol incubation. Oestriol and 16-epi-oestriol were characterized from the incubation with 16-oxo-oestradiol.

The formation of progesterone by the human placenta
American Journal of Obstetrics and Gynecology, 1966Abstract The net synthesis of progesterone by human placental homogenates and isolated mitochondria has been described for the first time. The availability of possible blood borne precursors has been screened for in maternal and fetal sera extracts. There appears to be enough pregnenolone in fetal blood to act as one potential source of progesterone ...

Human Papillomavirus in the Cervix and Placenta
Obstetrics & Gynecology, 2000To determine the prevalence and association of human papillomavirus (HPV) infection in the cervices and placentas of pregnant women.Cervical samples were taken from 179 of 226 women who had placental biopsies because of abnormal ultrasound findings or were older than 35 years, to detect HPV infections with hybrid capture II tests.

Polyclonal antibodies to human placenta lysyl oxidase (Kuivaniemi et al., 1984) were used to localize the enzyme at ultrastructural level in human placenta, skin and aorta, by using the indirect immunogold method. The antibodies were tested on thin sections of tissues fixed and embedded in various experimental conditions. With all methods employed, the

Estrogen sulfotransferase in human placenta
Journal of Steroid Biochemistry, 1985Human placental estrogen sulfotransferase (ESFT) was partially purified from the term placental cytosol by (NH4)2SO4 precipitation and agarose gel chromatography. Additional purifications caused a rapid loss of the enzyme activity. The activity was abolished by isoelectrofocusing but partially retained by chromatofocusing.

Urokinase Inhibitor in Human Placenta
Nature, 1968FIBRINOLYTIC activity in the blood markedly decreases in the later months of pregnancy and in labour, but rapidly returns to normal after delivery1–3. Brakman and Astrup4 observed a significant increase in the selective inhibition of fibrinolysis induced by urokinase in plasma and serum of pregnant women, and their findings suggested that an inhibitory
