Bacteria localization and chorion thinning among preterm premature rupture of membranes.

open access: yesPLoS ONE, 2014
ObjectiveBacterial colonization of the fetal membranes and its role in pathogenesis of membrane rupture is poorly understood. Prior retrospective work revealed chorion layer thinning in preterm premature rupture of membranes (PPROM) subjects.

Ultrastructural studies of the morphological variations of the egg surface and envelopes of the African catfish Clarias gariepinus (Burchell, 1822) before and after fertilisation with a discussion of fertilisation mechanism

open access: yesScientia Marina, 2006
Much of the existing knowledge of the mechanisms involved in teleost fertilisation is based on a few small model species that have no commercial value. Research is therefore urgently required to address mechanisms involved in fertilisation in species of ...

Placental markers of miscarriage

open access: yesPatologìâ, 2021
Successful implantation involves a high degree of development of spiral arteries, combined with high proliferative activity, which ensures the formation of a healthy placenta, full uterine-placental circulation, and the birth of a healthy child.

SLC20a1/PiT-1 is required for chorioallantoic placental morphogenesis

open access: yesVascular Biology, 2023
The placenta mediates the transport of nutrients, such as inorganic phosphate (Pi), between the maternal and fetal circulatory systems. The placenta itself also requires high levels of nutrient uptake as it develops to provide critical support for fetal ...

Fetal Membrane Epigenetics

open access: yesFrontiers in Physiology, 2020
The characteristics of fetal membrane cells and their phenotypic adaptations to support pregnancy or promote parturition are defined by global patterns of gene expression controlled by chromatin structure.

Standardized reporting of amnion and amnion/chorion allograft data for wound care

open access: yesHealth Science Reports, 2022
Background The favorable biological and mechanical properties of the most common components of the placenta, the amnion and chorion, have been explored for regenerative medical indications. The use of the combination of amnion and chorion has also become

Yellow-y Functions in Egg Melanization and Chorion Morphology of the Asian Tiger Mosquito, Aedes albopictus

open access: yesFrontiers in Cell and Developmental Biology, 2021
The Asian tiger mosquito, Aedes albopictus, is one of the most serious public health pests, which can transmit various vector-borne diseases. Eggs from this mosquito species become dark black shortly after oviposition and exhibit high desiccation ...

Chorion Villus Biopsy [PDF]

open access: yesClinics in Obstetrics and Gynaecology, 1985
Chorion villus biopsy answers the pressing need for early prenatal diagnosis. The technique is carried out at about 10 weeks gestation and in most instances this tissue is amenable to direct analysis without culture. This technique is particularly suitable for gene probe diagnosis.

The cellular localization of chorionic somatomammotrophin in ovine chorion [PDF]

open access: yesReproduction, 1982
Sections of Days 12 to 55 sheep chorion, embedded at low temperature in glycol methacrylate, were exposed to rabbit anti-ovine chorionic somatomammotrophin (oCS) to ascertain the distribution of oCS. This hormone was first detectable on Day 14, when the cytoplasm of each chorionic cell displayed a low level of fluorescence surrounding droplets which ...
