Lactating rats exhibit stable individual differences in pup licking/grooming (LG) over the first week postpartum. Such naturally occurring variations in maternal behavior are associated with differences in estrogen-inducible oxytocin receptors in the medial preoptic area (MPOA) of the hypothalamus. We compared levels of ER and ER mRNA in the MPOA of lactating High or Low LG mothers as well as i...

Treatment of lactating rats with the anti-progestin Mifepristone or Onapristone adversely affects growth of their litters. The present studies aimed to elucidate the underlying mechanism. The treatment did not interfere with the behavioural interactions between mothers and pups, which are required for normal litter growth. Treatment with the antagonists had a stimulatory action on ovarian oestr...

BACKGROUND There are many advantages of breast milk for infants. Many factors can affect the volume and composition of breast milk. One of them is the maternal diet. The objective of this study is to determine the effect of Ramadan fasting on maternal nutrition and breast milk composition. METHODS A total of 21 breast-feeding mothers aged between 17 and 38 years who fasted during Ramadan mont...

Iodine deficiency is an important nutritional deficiency, with more than 2 billion people worldwide estimated to be at risk. The developing fetus and young children are particularly at risk. During pregnancy and lactation, iodine requirements increase, whether in iodine-poor or iodine-sufficient countries, making the mother and the developing fetus vulnerable. The American Thyroid Association (...

Observational studies and randomized clinical trials demonstrating that antiretroviral prophylaxis of the breastfeeding infant or triple-drug antiretroviral prophylaxis of the lactating mother can significantly affect the risk of postnatal transmission of HIV via breast milk have recently become available. In resource-limited countries, breastfeeding is a cornerstone of infant survival. While s...

BACKGROUND Optimal nutrition for lactating mothers is importance for mother and infants' health and well-being. We determined the nutrient intake and dietary changes during the first 3-month of lactation, and its potential effect on health and disease risk. METHOD Personal interviews were conducted to collect a 24 h diet recall questionnaire from 199 healthy lactating women in the postpartum ...

Lactating animals consume greater amounts of food than non-reproductive animals, but energy intake appears to be limited in late lactation. The heat dissipation limit theory suggests that the food intake of lactating mice is limited by the capacity of the mother to dissipate heat. Lactating mice should therefore have high body temperatures (Tb), and changes in energy intake during lactation sho...

OBJECTIVE To present an updated review on common problems associated with breastfeeding and their management. SOURCE OF DATA A comprehensive bibliographic review on the issue was performed by searching publications from the MEDLINE database and from national and international organizations. Books and some key articles cited in other sources were also selected. SUMMARY OF THE FINDINGS Severa...
