Research on the fetus and newborn is of the greatest importance in contributing to the health and welfare of the entire population. Such research, motivated by humane concern, should be continued and fostered, subject to adequate and clearly defined safeguards.#{176} The American Academy of Pediatrics recogmzes that through research involving previable fetuses, new knowledge may be gained which...

BACKGROUND Fetus in fetu is a rare congenital anomaly and is defined as a monozygotic twin incorporated into the abdomen of its sibling during development. Fetus in fetu is often overlooked in the differential diagnosis of an abdominal mass. Unlike teratomas, fetus in fetu is a benign disorder. CASE PRESENTATION We describe the clinical characteristics of two patients, a thirty-months old boy...

The consequences of viral infection during pregnancy include impact on fetal and maternal immune responses and on fetal development. Transplacental infection in cattle with noncytopathic bovine viral diarrhea virus (ncpBVDV) during early gestation results in persistently infected (PI) fetuses with life-long viremia and susceptibility to infections. Infection of the fetus during the third trimes...

The hypothesis that anencephalus stems from fetus-fetus interactions in dizygotic twin pairs is examined by comparing the epidemiological predictions of the hypothesis with available observations. The hypothesis itself was based upon the disease-discordance and sex-concordance characteristics of twin pairs affected with anencephalus, and upon the sex ratio of the disease itself. The testable pr...

phenobarbital is a phenobarbiturate used as a sedative, anticonvulsant, or hypnotic with the doses prescribed and can cause teratogenic effects. the goal of this study was to examine an alternative method for the recognition of the mechanism or the bimolecular potential changes in mice fetus caused by phenobarbital using ftir micro spectroscopy. the mice were injected with phenobarbital (120mg/...
