Lactate uptake by liver is markedly increased in late-pregnant and mid-lactating rats without concomitant changes in its availability. Glycerol contribution to the liver 3-C unit uptake is only significant at term gestation (50% of lactate uptake) but almost negligible at mid-lactation (10% of lactate uptake). Pyruvate is only taken up by the liver of 15-day lactating rats. As a general trend, ...

Nursing has reciprocal benefits for both mother and infant, helping to promote maternal behavior and bonding. To test the "rewarding" nature of nursing, functional magnetic resonance imaging was used to map brain activity in lactating dams exposed to their suckling pups versus cocaine. Suckling stimulation in lactating dams and cocaine exposure in virgin females activated the dopamine reward sy...

Ectopic breast tissue is defined as glands located outside of the breast. Ectopic breast tissue should be excised because it may develop benign (fibroadenoma) or malignant pathologic processes. Less than forty cases of fibroadenomas have been reported in the literature. Although lactation changes can occur, lactating adenoma in the vulva are extremely rare. Only four cases have been reported. W...

Background. Vulva lactating adenoma is rare and may be misdiagnosed as adenocarcinoma in frozen section and aspiration cytology if breast tissue is not anticipated. Objective. To raise the awareness of lactating vulva ectopic breast lesion among clinicians and pathologists. Case Report. We present a case of vulva fibroadenoma associated with lactating adenoma in a 26-year-old Nigerian female. C...

Abstract Data used in these studies were part of another project described by Parsons et al. (2021). These evaluated heifer post-weaning intake classification on performance measurements two-, five- and eight-year-old lactating or non-lactating Angus females. We analyzed production data 57 pregnant, (Study 1) 54 lactating, non-pregnant 2) Heifer was calculated over 80 test days following weanin...

Compared with other nutrients, starch was the most under evaluated research topic in dairy nutrition for many years. Consequently, starch requirements for dairy cows were never established by the NRC (2001). Recently, improvements in the use of starch by lactating dairy cows garnered much interest by dairy farmers and their nutritionists, particularly over the past decade with the two-fold rise...

the purpose of this study was to determine the effects of feeding iron-deficient diet during pregnancy and lactation on maternal rats. a total number of 64 rats were divided into 4 groups (pregnant), (non pregnant), (lactating) and (non lactating) with 16 animals in each group. parameters used to evaluate the effects of dietary iron deficiency on the maternal animals were: iron contents of live...

In the lactating mammary gland, weaning produces mitochondrial cytochrome c release and nuclear DNA fragmentation, as determined by gel electrophoresis. This is followed by a significant decrease in lactation. Weaning for 2 h produces an early induction of the tumour suppressor/transcription factor p53, whereas the oncoprotein c-Jun and c-Jun N-terminal kinase are elevated after 24 h of weaning...

In lactating rats, ANG II receptor binding in the arcuate nucleus (ARH) and median eminence is decreased. To further evaluate brain angiotensinergic activity during lactation, we assessed angiotensinogen (AON) mRNA by in situ hybridization in forebrains of day 10 or 11 postpartum lactating and diestrous rats. AON mRNA was abundantly expressed in the ARH, preoptic, suprachiasmatic, supraoptic, p...
