Placental antibody transfer: influence of maternal HIV infection and placental malaria.
AIM To determine the influence of placental malaria, maternal HIV infection, and maternal hypergammaglobulinaemia on transplacental IgG antibody transfer. METHODS One hundred and eighty materno-neonatal pairs from a Malawian population were assessed. Cord and maternal serum samples were tested for total serum IgG antibody titres using nephelometry, and for specific IgG antibody titres to Stre...
متن کاملCorrelation of gut microbiota composition with colon adenomatous polyps
Microbiota is a collection of microorganisms that live in the oral cavity, respiratory tract and intestine of multicellular organisms. Microbiota exerts numerous physiological and pathological effects on the organism in which it resides. Increasing attention has been directed to the host-microbiota interaction, which is highly relevant to the development of carcinogenesis. Changes in the compos...
متن کاملPlacental transfer of choles
A tracer dose of cholester01-4-~~C was given daily in the diet of six pregnant guinea pigs to establish an isotopic steady state. At the time of parturition, maternal and fetal blood and fetal tissues were collected and analyzed for cholesterol content and cholesterol specific activity. A comparison of these specific activities in neonatal and maternal serum indicated that about 22% of the feta...
متن کاملPlacental transfer of naloxone.
Maternal and umbilical venous serum naloxone concentrations were measured after the i.v. (30 mothers) or i.m. (seven mothers) injection of naloxone 400 micrograms. Following i.v. naloxone there was rapid transfer to the fetus and therapeutic plasma concentrations could be expected in 1 or 2 min. However, following i.m. administration, neonatal concentrations were variable. In five non-pregnant ...
متن کاملIgG2 subclass isotype antibody and intrauterine infections
The foetus is dependent on its mother for passive immunity involving receptor-mediated specific transport of antibodies. IgG antibody is present in highest concentration in serum and is the only antibody type that can cross the placenta efficiently, except for its IgG2 subclass. Most of the pathogenic manifestations affecting the foetus involve capsular antigens and polysaccharides of pathogens...
