Factors affecting antenatal care attendance by mothers of Pacific infants living in New Zealand.

Aims: To describe antenatal care attendance by mothers of Pacific infants recently delivered at Middlemore Hospital, South Auckland and to examine the demographic and psychosocial factors associated with late initiation of care and inadequate attendance.

Methods: The data were gathered as part of the Pacific Islands Families: First Two Years of Life (PIF) Study in which 1365 birth mothers in the cohort (n=1376) were interviewed when their infants were six weeks old about their antenatal care attendance.

Results: Almost all (99.

Assembly and cell surface expression of homomeric and heteromeric 5-HT3 receptors: the role of oligomerization and chaperone proteins.

The ability of differing subunit combinations of 5-HT3 receptors to form functional cell surface receptors was analyzed by a variety of approaches. The results revealed that 5-HT3 receptor assembly occurred within the endoplasmic reticulum (ER) and involved the interaction with chaperone proteins. The 5-HT3A subunit could assemble into functional homomeric receptors that were expressed on the cell surface.
