Transporter-mediated processes in the lactating mammary gland may explain the significant accumulation of certain drugs in breast milk. The purpose of this study was to identify potential candidate drug transport proteins involved in drug accumulation in milk. Quantitative reverse transcription-polymerase chain reaction methods were developed to determine the relative RNA levels of 30 different...
The effects of dehydration on mechanisms of water balance and milk synthesis were investigated in ten lactating Gambian women who were fasting during Ramadan. Ten non-pregnant, non-lactating women acted as controls. Fasting consisted of total water abstention from 05.00 hours to 19.30 hours and was accompanied by high insensible water losses. Lactating women lost 7.6% of their total body water ...
We measured daily energy expenditure (DEE) and water turnover rates in lactating and non-lactating short beaked echidnas (Tachyglossus aculeatus) using the doubly labelled water technique during the lactation period in spring. Reproductively inactive echidnas were on average significantly heavier (median: 3354 g; range: 2929-3780 g; N=4) than lactating females (median: 2695 g; range: 2690-2715 ...
Some metabolic alterations were evaluated in Wistar rats which received control or low-protein (17%; 6%) diets, from the pregnancy until the end of lactation: control non-lactating (CNL), lactating (CL), low-protein non-lactating (LPNL) and lactating (LPL) groups. Despite the increased food intake by LPL dams, both LP groups reduced protein intake and final body mass was lower in LPL. Higher se...
Apixaban, a potent and highly selective factor Xa inhibitor, is currently under development for treatment of arterial and venous thrombotic diseases. The distribution, metabolism, and elimination of [(14)C]apixaban were investigated in male, female, pregnant, and lactating rats after single oral doses. Tissue distribution of radioactivity in rats was measured using quantitative whole-body autor...
BACKGROUND RFamide-related peptide-3 (RFRP-3) inhibits gonadotropin releasing hormone (GnRH) and luteinizing hormone (LH) secretion in rats. This study evaluates the effects of litter size and suckling intensity on RFRP mRNA expression in the dorsomedial hypothalamic nucleus (DMH) of rats. MATERIALS AND METHODS A total of 32 pregnant and 4 non-lactating ovariectomized (control group) Sprague-...
Female ruminants are susceptible to spontaneous ketosis arising at times of high productive demand. The dairy cow is most susceptible during the first 7 weeks of lactation, whereas the ewe is susceptible, particularly when multifoetate, during the last month of pregnancy. The disorder is characterized by signs of carbohydrate insufficiency and adipose-tissue mobilization. Those of carbohydrate ...
INTRODUCTION Lactating adenoma is a benign condition, representing the most prevalent breast lesion in pregnant women and during puerperium; in this paper, a case of a woman with lactating adenoma occurring during the first trimester of pregnancy is reported. There have been no reports in the literature, according to our search, focusing on magnetic resonance imaging findings in cases of lactat...
Acetyl-CoA carboxylase, the major flux determining enzyme for lipogenesis is controlled both acutely through reversible phosphorylation [ I ] and chronically through changes in gene transcription [2] Regulation of the acetyl-CoA carboxylase gene is complex due to the use of a dual promoter system and alternative exon splicing resulting in transcripts with the same open reading frame but with he...
