OBJECTIVES To assess potential infant exposure to bupropion and its active metabolites in breast milk such as would occur during treatment to prevent post-partum relapse to tobacco use, and to compare the concentrations of bupropion in urine and saliva with plasma and breast milk. DESIGN AND SETTING Cohort study, outpatient clinical research centre. SUBJECTS Ten healthy post-partum voluntee...

BACKGROUND There is seemingly consistent and compelling evidence that there is no association between breastfeeding and breast cancer. An assumption follows that milk borne viruses cannot be associated with human breast cancer. We challenge this evidence because past breastfeeding studies did not determine "exposure" of newborn infants to colostrum and breast milk. METHODS We conducted a pros...

From the fusion of the murine myeloma P3- X63-Ag8-U1 with spleen cells from a mouse immunized with the human breast cancer cell line MCF-7, 88 hybridomas producing antibodies reacting with the immunizing cells were obtained. After a first screening on human leukocytes, red blood cells, and platelets and on human and fetal calf serum, three monoclonal antibodies, MBr1, MBr2, and MBr3, with speci...

Breast milk is the recommended nutrition for infants. For preterm infants, when mother's milk is not available, pasteurized donor milk is recommended (1). Non-Hispanic black mothers are at increased risk for having a preterm birth and for not breastfeeding (2,3); however, it is not known whether demographic disparities exist in the use of breast milk in neonatal intensive care units (NICUs). Da...

A murine model has been developed to study maternal transmission of the temperature-sensitive Moloney murine leukemia virus (ts-1). The goal of this study was to confirm early and late mother-to-offspring transmission of the virus and demonstrate transmission via breast milk. A series of six experiments was performed using six groups of BALB/c mice. Group 1 consisted of pups born to ts-1-infect...

The unfavorable effects of neonatal immunodeficiency are limited by some naturally occurring compensatory mechanisms, such as the introduction of protective and immunological components of human milk in the infant. Breast-feeding maintains the maternal-fetal immunological link after birth, may favor the transmission of immunocompetence from the mother to her infant, and is considered an importa...

OBJECTIVE To determine vitamin A (retinol) and fat concentrations in breast milk during early lactation. METHODS Healthy lactating women (n 88) aged between 18 and 35 years were randomly selected for the study from urban, semi-urban, rural and estate (plantation) sectors of Galle District. Their anthropometry was recorded; breast milk samples were collected from the right breast one hour afte...

Background Peanut allergy is known to be one of the most severe food allergies. The aim of our breast milk study was to investigate the transfer of the most potent peanut allergen Ara h 2 into human breast milk in a German cohort. Therefore, the time courses of appearance after ingestion, the potential risk of sensitization to peanuts via breast milk in Germany and, if possible, the way Ara h 2...

The iron content of breast milk is often characterized as low. In fact, the amount of iron provided by breast milk appears to be adequate to prevent iron deficiency anemia for at least the first 6 months of life. However, if the same amount of iron is given in any food other than breast milk, this amount is inadequate and iron deficiency anemia does occur. Thus, iron in breast milk seems to be ...
