Transthyretin and the human placenta

Placenta, 2013
Since 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.

Arylsulphatases of human placenta

Clinica Chimica Acta, 1964
Abstract 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 ...

Human placenta gangliosides

Lipids, 1988
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

Lysosomes in Human Placenta

Nature, 1969
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.

Composition of the human placenta

American Journal of Obstetrics and Gynecology, 1946
Abstract The total lipid (phospholipid [cephalin, lecithin and sphingomyelin] free and combined cholesterol, cerebrosides and neutral fat) distribution in nine human placentas is reported. No great individual variations in the lipid pattern were noted. Of the total lipid, one-fourth was neutral fat.

The formation of progesterone by the human placenta

American Journal of Obstetrics and Gynecology, 1966
Abstract 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, 2000
To 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.

16-DEHYDROGENASE IN HUMAN PLACENTA

Acta Endocrinologica, 1975
ABSTRACT 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.

Antioxidant transport by the human placenta

Clinical Nutrition, 1998
We investigated the transfer of three antioxidants - melatonin, S-adenosyl methionine (SAM) and various forms of vitamin E - across the term, normal human placenta. The transport technique involved the single, isolated placental cotyledon system in vitro.
