Summary of ""Provoked" feto-maternal hemorrhage may represent insensible cell exchange in pregnancies from 6-22weeks gestational age."

To quantify spontaneous and provoked fetal to maternal cell exchange in the first half of pregnancy. Transfer of fetal red blood cells (FRBCs) into the maternal circulation during the first half of pregnancy is poorly characterized but of clinical relevance for miscarriage management and invasive procedures.

Uterine and fetal placental Doppler indices are associated with maternal cardiovascular function.

The mechanism underlying fetal-placental Doppler changes in pre-eclampsia and/or fetal growth restriction are unknown though both are associated with maternal cardiovascular dysfunction. We sought to ...

Increased placental T cell trafficking results in adverse neurobehavioral outcomes in offspring exposed to sub-chronic maternal inflammation.

Medical and Biotech [MESH] Definitions

Exchange of substances between the maternal blood and the fetal blood at the PLACENTA via PLACENTAL CIRCULATION. The placental barrier excludes microbial or viral transmission.

Excess blood loss from uterine bleeding associated with OBSTETRIC LABOR or CHILDBIRTH. It is defined as blood loss greater than 500 ml or of the amount that adversely affects the maternal physiology, such as BLOOD PRESSURE and HEMATOCRIT. Postpartum hemorrhage is divided into two categories, immediate (within first 24 hours after birth) or delayed (after 24 hours postpartum).

Transmission of genetic characters, qualities, and traits, solely from maternal extra-nuclear elements such as MITOCHONDRIAL DNA or MATERNAL MESSENGER RNA.

A syndrome characterized by multiple abnormalities, MENTAL RETARDATION, and movement disorders. Present usually are skull and other abnormalities, frequent infantile spasms (SPASMS, INFANTILE); easily provoked and prolonged paroxysms of laughter (hence "happy"); jerky puppetlike movements (hence "puppet"); continuous tongue protrusion; motor retardation; ATAXIA; MUSCLE HYPOTONIA; and a peculiar facies. It is associated with maternal deletions of chromosome 15q11-13 and other genetic abnormalities. (From Am J Med Genet 1998 Dec 4;80(4):385-90; Hum Mol Genet 1999 Jan;8(1):129-35)

High molecular weight, insoluble polymers which contain functional groups that are capable of undergoing exchange reactions (ION EXCHANGE) with either cations or anions.
