Benzodiazepine use in pregnancy and major malformations or oral cleft: meta-analysis of cohort and case-control studies

Objective: To determine if exposure to benzodiazepines during the first trimester of pregnancy increases risk of major malformations or cleft lip or palate.

A pregnancy-specific glycoprotein is expressed in the brain and serves as a receptor for mouse hepatitis virus.

Mouse hepatitis virus (MHV), a murine coronavirus known to cause encephalitis and demyelination, uses murine homologues of carcinoembryonic antigens as receptors. However, the expression of these receptors is extremely low in the brain. By low-stringency screening of a mouse brain cDNA library, we have identified a member of the pregnancy-specific glycoprotein (PSG) subgroup of the carcinoembryonic antigen gene family. Unlike other PSG that are expressed in the placenta, it is expressed predominantly in the brain. Transfection of the cDNA into COS-7 cells, which lack a functional MHV receptor, conferred susceptibility to infection by some MHV strains, including A59, MHV-2, and MHV-3, but not JHM. Thus, this is a virus strain-specific receptor. The detection of multiple receptors for MHV suggests the flexibility of this virus in receptor utilization. The identification of this virus in receptor utilization. The identification of a PSG predominantly expressed in the brain also expands the potential functions of these molecules.

The Psychology of Adolescent Out-of Wedlock Pregnancy and Childbearing

Illegitimate adolescent pregnancy creates a variety of problems, beginning with the difficult decision about whether or not to terminate the pregnancy. If the pregnancy is carried to term, choices follow regarding marriage or single parenthood and keeping or relinquishing the child. All of these choices involve consequences for the adolescent, many of them negative ones. This paper examines the problem of out-of-wedlock teen pregnancy and its possible psychological sources. It also introduces a method for analyzing the psychology of unwed teen pregnancy and childbearing and reviews the literature on the subject by this method.
